Background

Blood Pressure related disease affected 118 million people in India in the year 2000; this figure will double by 2025. Around one in four adults in rural India have hypertension, and of those, only a minority are accessing appropriate care. Health systems in India face substantial challenges to meet these gaps in care, and innovative solutions are needed.

Methods

We hypothesise that a multifaceted intervention involving capacity strengthening of primary healthcare doctors and non-physician healthcare workers through use of a mobile device-based clinical decision support system will result in improved blood pressure control for individuals at high risk of a cardiovascular disease event when compared with usual healthcare. This intervention will be implemented as a stepped wedge, cluster randomised controlled trial in 18 primary health centres and 54 villages in rural Andhra Pradesh involving adults aged ≥40 years at high cardiovascular disease event risk (approximately 15,000 people). Cardiovascular disease event risk will be calculated based on World Health Organisation/International Society of Hypertension’s region-specific risk charts. Cluster randomisation will occur at the level of the primary health centres. Outcome analyses will be conducted blinded to intervention allocation.

Expected outcomes

The primary study outcome is the difference in the proportion of people meeting guideline-recommended blood pressure targets in the intervention period vs. the control period. Secondary outcomes include mean reduction in blood pressure levels; change in other cardiovascular disease risk factors, including body mass index, current smoking, reported healthy eating habits, and reported physical activity levels; self-reported use of blood pressure and other cardiovascular medicines; quality of life (using the EQ-5D); and cardiovascular disease events (using hospitalisation data). Trial outcomes will be accompanied by detailed process and economic evaluations.

Significance

The findings are likely to inform policy on a scalable strategy to overcome entrenched inequities in access to effective healthcare for under-served populations in low and middle income country settings.

Nonadherence with prescribed drug regimens is a pervasive medical problem. Multiple variables affecting physicians and patients contribute to nonadherence, which negatively affects treatment outcomes. In patients with hypertension, medication nonadherence is a significant, often unrecognized, risk factor that contributes to poor blood pressure control, thereby contributing to the development of further vascular disorders such as heart failure, coronary heart disease, renal insufficiency, and stroke. Analysis of various patient populations shows that choice of drug, use of concomitant medications, tolerability of drug, and duration of drug treatment influence the prevalence of nonadherence. Intervention is required among patients and healthcare prescribers to increase awareness of the need for improved medication adherence. Within this process, it is important to identify indicators of nonadherence within patient populations. This review examines the prevalence of nonadherence as a risk factor in the management of chronic diseases, with a specific focus on antihypertensive medications. Factors leading to increased incidence of nonadherence and the strategies needed to improve adherence are discussed. Medication nonadherence, defined as a patient's passive failure to follow a prescribed drug regimen, remains a significant concern for healthcare professionals and patients. On average, one third to one half of patients do not comply with prescribed treatment regimens.[1-3] Nonadherence rates are relatively high across disease states, treatment regimens, and age groups, with the first several months of therapy characterized by the highest rate of discontinuation.[3] In fact, it has recently been reported that low adherence to beta-blockers or statins in patients who have survived a myocardial infarction results in an increased risk of death.[4] In addition to inadequate disease control, medication nonadherence results in a significant burden to healthcare utilization - the estimated yearly cost is $396 to $792 million.[1] Additionally, between one third and two thirds of all medication-related hospital admissions are attributed to nonadherence.[5,6]Cardiovascular disease, which accounts for approximately 1 million deaths in the United States each year, remains a significant health concern.[7] Risk factors for the development of cardiovascular disease are associated with defined risk-taking behaviors (eg, smoking), inherited traits (eg, family history), or laboratory abnormalities (eg, abnormal lipid panels).[7] A significant but often unrecognized cardiovascular risk factor universal to all patient populations is medication nonadherence; if a patient does not regularly take the medication prescribed to attenuate cardiovascular disease, no potential therapeutic gain can be achieved. Barriers to medication adherence are multifactorial and include complex medication regimens, convenience factors (eg, dosing frequency), behavioral factors, and treatment of asymptomatic conditions.[2] This review highlights the significance of nonadherence in the treatment of hypertension, a silent but life-threatening disorder that affects approximately 72 million adults in the United States.[7] Hypertension often develops in a cluster with insulin resistance, obesity, and hypercholesterolemia, which contributes to the risk imposed by nonadherence with antihypertensive medications. Numerous strategies to improve medication adherence are available, from enhancing patient education to providing medication adherence information to the healthcare team and will be discussed in this article.  相似文献

Eliminating four behavioral risk factors (tobacco use, physical inactivity, unhealthy diet and harmful use of alcohol) could contribute to a decrease of up to 80% in burden of non-communicable diseases, including cardiovascular diseases. Primary healthcare providers have a unique position within the healthcare system, which allows them to actively contribute to the prevention of cardiovascular behavioral risk factors (CVBRFs) by providing individual counseling. The aim of this article is to show the change in frequency and the effects of counseling on CVBRFs by healthcare providers between two periods: up until 2003 and between 2003 and 2008. Results, obtained within the CroHort study, show a low frequency and undesired effects of counseling within the healthcare system in both studied periods. This points to a lack of consistency with which the healthcare system tackles prevention of behavioral risk factors for cardiovascular diseases.  相似文献

OBJECTIVE: To assess the effectiveness of multiple risk factor intervention in reducing cardiovascular risk factors, total mortality, and mortality from coronary heart disease among adults. DESIGN: Systematic review and meta-analysis of randomised controlled trials in workforces and in primary care in which subjects were randomly allocated to more than one of six interventions (stopping smoking, exercise, dietary advice, weight control, antihypertensive drugs, and cholesterol lowering drugs) and followed up for at least six months. SUBJECTS: Adults aged 17-73 years, 903000 person years of observation were included in nine trials with clinical event outcomes and 303000 person years in five trials with risk factor outcomes alone. MAIN OUTCOME MEASURES: Changes in systolic and diastolic blood pressure, smoking rates, blood cholesterol concentrations, total mortality, and mortality from coronary heart disease. RESULTS: Net decreases in systolic and diastolic blood pressure, smoking prevalence, and blood cholesterol were 4.2 mm Hg (SE 0.19 mm Hg), 2.7 mm Hg (0.09 mm Hg), 4.2% (0.3%), and 0.14 mmol/l (0.01 mmol/l) respectively. In the nine trials with clinical event end points the pooled odds ratios for total and coronary heart disease mortality were 0.97 (95% confidence interval 0.92 to 1.02) and 0.96 (0.88 to 1.04) respectively. Statistical heterogeneity between the studies with respect to changes in mortality and risk factors was due to trials focusing on hypertensive participants and those using considerable amounts of drug treatment, with only these trials showing significant reductions in mortality. CONCLUSIONS: The pooled effects of multiple risk factor intervention on mortality were insignificant and a small, but potentially important, benefit of treatment (about a 10% reduction in mortality) may have been missed. Changes in risk factors were modest, were related to the amount of pharmacological treatment used, and in some cases may have been overestimated because of regression to the mean, lack of intention to treat analyses, habituation to blood pressure measurement, and use of self reports of smoking. Interventions using personal or family counselling and education with or without pharmacological treatments seem to be more effective at reducing risk factors and therefore mortality in high risk hypertensive populations. The evidence suggests that such interventions implemented through standard health education methods have limited use in the general population. Health protection through fiscal and legislative measure may be more effective.  相似文献

The state of health communication for a given population is a function of several tiers of structure and process: government policy, healthcare directives, healthcare structure and process, and the ethnosocial realities of a multicultural society. Common yet specific to these tiers of health communication is the interpersonal and intergroup use of language in all its forms. Language is the most common behavior exhibited by humankind. Its use at all tiers determines quality of healthcare and quality of life for healthcare consumers: patients and their families. Of note, at the consumer end, mounting evidence demonstrates that barriers to health communication contribute to poorer access to care, quality of care, and health outcomes. The lack of comprehensible and usable written and spoken language is a major barrier to health communication targeting primary and secondary disease prevention and is a major contributor to the misuse of healthcare, patient noncompliance, rising healthcare costs. In this paper, we cursorily examine the relationship among government policy, institutional directives, and healthcare structure and process and its influence on the public health, especially vulnerable populations. We conclude that limited health communication in the context of changing healthcare environments and diverse populations is an important underpinning of rising healthcare costs and sustained health disparities. More research is needed to improve communication about health at all tiers and to develop health communication interventions that are usable by all population groups.  相似文献

PURPOSE OF REVIEW: Imaging of the arterial wall yields validated surrogate markers that can provide an early indication with regards to efficacy of novel cardiovascular drugs. This paper attempts to address the use of atherosclerosis imaging as a benchmarking tool for a well informed decision whether to proceed to large morbidity and mortality studies in the assessment of a novel therapeutic strategy. RECENT FINDINGS: Imaging of the artery wall can be used to evaluate individual cardiovascular risk and has additive value over conventional risk scores as it directly addresses the disease process. In controlled clinical trials, vascular imaging has shown that the efficacy of lipid-modifying pharmacotherapy can be evaluated in both high and low-risk populations and that the findings parallel outcomes of clinical studies with similar interventions. SUMMARY: Arterial imaging may provide the first glimpse of the efficacy or failure of a novel strategy to combat atherosclerosis. These findings suggest that vascular imaging could be employed to probe whether or not a large morbidity and mortality endpoint study should be the next step in a clinical development program.  相似文献

Healthy nutrition is accepted as a cornerstone of public health strategies for reducing the risk of noncommunicable conditions such as obesity, cardiovascular disease, and related morbidities. However, many research studies continue to focus on single or at most a few factors that may elicit a metabolic effect. These reductionist approaches resulted in: (1) exaggerated claims for nutrition as a cure or prevention of disease; (2) the wide use of empirically based dietary regimens, as if one fits all; and (3) frequent disappointment of consumers, patients, and healthcare providers about the real impact nutrition can make on medicine and health. Multiple factors including environment, host and microbiome genetics, social context, the chemical form of the nutrient, its (bio)availability, and chemical and metabolic interactions among nutrients all interact to result in nutrient requirement and in health outcomes. Advances in laboratory methodologies, especially in analytical and separation techniques, are making the chemical dissection of foods and their availability in physiological tissues possible in an unprecedented manner. These omics technologies have opened opportunities for extending knowledge of micronutrients and of their metabolic and endocrine roles. While these technologies are crucial, more holistic approaches to the analysis of physiology and environment, novel experimental designs, and more sophisticated computational methods are needed to advance our understanding of how nutrition influences health of individuals.  相似文献

The use of electronic health records has skyrocketed following the 2009 HITECH Act, which provides financial incentives to health care providers for the “meaningful use” of electronic medical record systems. An important component of the “Meaningful Use” legislation is the integration of Clinical Decision Support Systems (CDSS) into the computerized record, providing up-to-date medical knowledge and evidence-based guidance to the physician at the point of care. As reimbursement is increasingly tied to process and clinical outcomes, CDSS will be integral to future medical practice. Studies of CDSS indicate improvement in preventive services, appropriate care, and clinical and cost outcomes with strong evidence for CDSS effectiveness in process measures. Increasing provider adherence to CDSS recommendations is essential in improving CDSS effectiveness, and factors that influence adherence are currently under study.  相似文献

ABSTRACT: BACKGROUND: World-wide healthcare systems are faced with an epidemic of type 2 diabetes. In the United Kingdom, clinical care is primarily provided by general practitioners (GPs) rather than hospital specialists. Intermediate care clinics for diabetes (ICCD) potentially provide a model for supporting GPs in their care of people with poorly controlled type 2 diabetes and in their management of cardiovascular risk factors. This study aims to (1) compare patients with type 2 diabetes registered with practices that have access to an ICCD service with those that have access only to usual hospital care; (2) assess the cost-effectiveness of the intervention; and (3) explore the views and experiences of patients, health professionals and other stakeholders. METHODS: This two-arm cluster randomized controlled trial (with integral economic evaluation and qualitative study) is set in general practices in three UK Primary Care Trusts. Practices are randomized to one of two groups with patients referred to either an ICCD (intervention) or to hospital care (control).Intervention group: GP practices in the intervention arm have the opportunity to refer patients to an ICCD - a multidisciplinary team led by a specialist nurse and a diabetologist. Patients are reviewed and managed in the ICCD for a short period with a goal of improving diabetes and cardiovascular risk factor control and are then referred back to practice.orControl group: Standard GP care, with referral to secondary care as required, but no access to ICCD.Participants are adults aged 18 years or older who have type 2 diabetes that is difficult for their GPs to control. The primary outcome is the proportion of participants reaching three risk factor targets: HbA1c (<=7.0%); blood pressure (<140/80); and cholesterol (<4 mmol/l), at the end of the 18-month intervention period. The main secondary outcomes are the proportion of participants reaching individual risk factor targets and the overall 10-year risks for coronary heart disease(CHD) and stroke assessed by the United Kingdom Prospective Diabetes Study (UKPDS) risk engine. Other secondary outcomes include body mass index and waist circumference, use of medication, reported smoking, emotional adjustment, patient satisfaction and views on continuity, costs and health related quality of life. We aimed to randomize 50 practices and recruit 2,555 patients. DISCUSSION: Forty-nine practices have been randomized, 1,997 patients have been recruited to the trial, and 20 patients have been recruited to the qualitative study. Results will be available late 2012.Trial registration[ClinicalTrials.gov: Identifier NCT00945204].  相似文献

Psychotropic drugs (hypno-sedatives, antidepressants and antipsychotics) are commonly used in the older population. On the long term, psychotropic drug use in older persons is associated with several negative functional outcomes such as an increased risk of falls. Gradual withdrawal of psychotropic drugs in older persons is feasible and leads to a significant reduction of falls. Both withdrawal of psychotropic drugs as well as the initiation of appropriate treatment with psychotropic drugs requires knowledge, consultation and cooperation between disciplines and a mentality change among healthcare professionals. In order to inform and support healthcare professionals, the Centre of Expertise for Fall and Fracture Prevention Flanders developed three clinical practice algorithms for the appropriate use of psychotropic drugs in older persons with high risk of falls and a fact sheet with background information.  相似文献

ABSTRACT: BACKGROUND: Despite the availability of evidence-based psychotherapies for depression and anxiety, they are underused in non-mental health specialty settings such as primary care. Hybrid effectiveness-implementation designs have the potential to evaluate clinical and implementation outcomes of evidence-based psychotherapies to improve their translation into routine clinical care practices. METHODS: This protocol article discusses the study methodology and implementation strategies employed in an ongoing, hybrid, type 2 randomized controlled trial with two primary aims: (1) to determine whether a brief, manualized cognitive behavioral therapy administered by Veterans Affairs Primary Care Mental Health Integration program clinicians is effective in treating depression and anxiety in a sample of medically ill (chronic cardiopulmonary diseases) primary care patients and (2) to examine the acceptability, feasibility, and preliminary outcomes of a focused implementation strategy on improving adoption and fidelity of brief cognitive behavioral therapy at two Primary Care-Mental Health Integration clinics. The study uses a hybrid type 2 effectiveness/implementation design to simultaneously test clinical effectiveness and to collect pilot data on a multifaceted implementation strategy that includes an online training program, audit and feedback of session content, and internal and external facilitation. Additionally, the study engages the participation of an advisory council consisting of stakeholders from Primary Care-Mental Health Integration, as well as regional and national mental health leaders within the Veterans Administration. It targets recruitment of 320 participants randomized to brief cognitive behavioral therapy (n = 200) or usual care (n = 120). Both effectiveness and implementation outcomes are being assessed using mixed methods, including quantitative evaluation (e.g., intent-to-treat analyses across multiple time points) and qualitative methods (e.g., focus interviews and surveys from patients and providers). Patient-effectiveness outcomes include measures of depression, anxiety, and physical health functioning using blinded independent evaluators. Implementation outcomes include patient engagement and adherence and clinician brief cognitive behavioral therapy adoption and fidelity. CONCLUSIONS: Hybrid designs are needed to advance clinical effectiveness and implementation knowledge to improve healthcare practices. The current article describes the rationale and challenges associated with the use of a hybrid design for the study of brief cognitive behavioral therapy in primary care. Although trade-offs exist between scientific control and external validity, hybrid designs are part of an emerging approach that has the potential to rapidly advance both science and practice.

The population living in Central Appalachia is disproportionately impacted by lung disease. This is driven, in part, by occupational hazards and environmental exposures. However, it is more than coal dust that is driving the ongoing disparity of lung disease in the region. This review describes how the decline of the coal mine industry and subsequent rise of unemployment, poverty, and educational disparities have increased risk for worse pulmonary health outcomes in the region. Additional challenges related to healthcare access, substance use, cultural characteristics, and social capital are highlighted in their relation to pulmonary health within Central Appalachia. Lastly, the review describes strategies that hold promise to reduce regional health disparities. Several healthcare and community-centered initiatives are highlighted as successful examples of collaborative efforts working towards improving pulmonary health outcomes in the region. However, significant challenges related to social, economic, and environmental factors remain. Addressing these social determinants of health must be a paramount concern for healthcare, community and political leaders seeking to impact change and improve the health and well-being of this vulnerable population.  相似文献

PURPOSE OF REVIEW: The risk of cardiovascular disease is markedly increased in people with type 2 diabetes. There is abundant epidemiological and clinical trial evidence that lipid abnormalities play a major role in the pathogenesis of atherosclerotic vascular disease in diabetes. Although the benefits of lipid-lowering therapy are well established in people without diabetes, the evidence in people with diabetes is not as well established. RECENT FINDINGS: Recent population studies of lipid-lowering therapy and cardiovascular disease outcomes that included people with diabetes and performed a separate subgroup analysis were reviewed. Lipid lowering with statins and fibrates is effective in improving cardiovascular disease outcomes in diabetes, and their effectiveness is similar to that in the non-diabetic population. This effect is well established in secondary prevention and is accumulating for primary prevention. SUMMARY: Individuals with diabetes require aggressive management of dyslipidaemia as part of an overall management strategy to reduce the risk of cardiovascular disease. Individuals with a previous cardiovascular disease event should be on lipid-lowering therapy, whereas in those who have not had a previous cardiovascular disease event, the decision to use lipid-lowering therapy should be based on lipid levels and the overall risk of a future event. The results of large studies that are currently in progress specifically in people with diabetes should resolve outstanding questions in relation to lipid-lowering therapy in diabetes.  相似文献

A tremendous amount of scientific evidence regarding the physiology and physiopathology of high blood pressure combined with a sophisticated therapeutic arsenal is at the disposal of the medical community to counteract the overall public health burden of hypertension. Ample evidence has also been gathered from a multitude of large-scale randomized trials indicating the beneficial effects of current treatment strategies in terms of reduced hypertension-related morbidity and mortality.In spite of these impressive advances and, deeply disappointingly from a public health perspective, the real picture of hypertension management is overshadowed by widespread diagnostic inaccuracies (underdiagnosis, overdiagnosis) as well as by treatment failures generated by undertreatment, overtreatment, and misuse of medications.The scientific, medical and patient communities as well as decision-makers worldwide are striving for greatest possible health gains from available resources.A seemingly well-crystallised reasoning is that comprehensive strategic approaches must not only target hypertension as a pathological entity, but rather, take into account the wider environment in which hypertension is a major risk factor for cardiovascular disease carrying a great deal of our inheritance, and its interplay in the constellation of other, well-known, modifiable risk factors, i.e., attention is to be switched from one's "blood pressure level" to one's absolute cardiovascular risk and its determinants. Likewise, a risk/benefit assessment in each individual case is required in order to achieve best possible results.Nevertheless, it is of paramount importance to insure generalizability of ABPM use in clinical practice with the aim of improving the accuracy of a first diagnosis for both individual treatment and clinical research purposes. Widespread adoption of the method requires quick adjustment of current guidelines, development of appropriate technology infrastructure and training of staff (i.e., education, decision support, and information systems for practitioners and patients). Progress can be achieved in a few years, or in the next 25 years.  相似文献

Background

The objective of this study was to evaluate the performance of risk scores (Framingham, Assign and QRISK2) in predicting high cardiovascular disease (CVD) risk in individuals rather than populations.

Methods and findings

This study included 1.8 million persons without CVD and prior statin prescribing using the Clinical Practice Research Datalink. This contains electronic medical records of the general population registered with a UK general practice. Individual CVD risks were estimated using competing risk regression models. Individual differences in the 10-year CVD risks as predicted by risk scores and competing risk models were estimated; the population was divided into 20 subgroups based on predicted risk. CVD outcomes occurred in 69,870 persons. In the subgroup with lowest risks, risk predictions by QRISK2 were similar to individual risks predicted using our competing risk model (99.9% of people had differences of less than 2%); in the subgroup with highest risks, risk predictions varied greatly (only 13.3% of people had differences of less than 2%). Larger deviations between QRISK2 and our individual predicted risks occurred with calendar year, different ethnicities, diabetes mellitus and number of records for medical events in the electronic health records in the year before the index date. A QRISK2 estimate of low 10-year CVD risk (<15%) was confirmed by Framingham, ASSIGN and our individual predicted risks in 89.8% while an estimate of high 10-year CVD risk (≥20%) was confirmed in only 48.6% of people. The majority of cases occurred in people who had predicted 10-year CVD risk of less than 20%.

Conclusions

Application of existing CVD risk scores may result in considerable misclassification of high risk status. Current practice to use a constant threshold level for intervention for all patients, together with the use of different scoring methods, may inadvertently create an arbitrary classification of high CVD risk.  相似文献

Simple and cost-effective tools that identify patients at increased risk for adverse cardiovascular events are actively sought. High resting sinus heart rate and first degree AV block are easily recognized and commonly encountered findings in a cardiology practice. A growing body of epidemiological and clinical evidence has been shown them to be independent predictors of all-cause and cardiovascular mortality, both in the general population and in patients with structural heart disease. This paper reviews the important role of heart rate and first degree AV block in predicting cardiovascular outcomes, examines the pathophysiological mechanisms underlying this increased risk, and discusses the effectiveness of available therapies to favorably modify these risk factors.  相似文献

ABSTRACT: BACKGROUND: Decreasing salt consumption can prevent cardiovascular diseases (CVD). Practically, it is difficult to promote people's awareness of daily salt intake and to change their eating habits in terms of reducing salt intake for better cardiovascular health. Health education programs visualizing daily dietary salt content and intake may promote lifestyle changes in patients at high risk of cardiovascular disease. METHODS: This is a cluster randomized trial. A total of 800 high-CVD-risk patients attending diabetes and hypertension clinics at health centers in Muang District, Chiang Rai province, Thailand, will be studied with informed consent. A health center recruiting 100 participants is a cluster, the unit of randomization. Eight clusters will be randomized into intervention and control arms and followed up for 1 year. Within the intervention clusters the following will be undertaken: (1) salt content in the daily diet will be measured and shown to study participants; (2) 24-hour salt intake will be estimated in overnight-collected urine and the results shown to the participants; (3) a dietician will assist small group health education classes in cooking meals with less salt. The primary outcome is blood pressure change at the 1-year follow-up. Secondary outcomes at the 1-year follow-up are estimated 24-hoursalt intake, incidence of CVD events and CVD death. The intention-to-treat analysis will be followed.Blood pressure and estimated 24-hour salt intake will be compared between intervention and control groups at the cluster and individual level at the 1-year follow-up. Clinical CVD events and deaths will be analyzed by time-event analysis. Retinal blood vessel calibers of CVD-risk patients will be assessed cross-sectionally. Behavioral change to reduce salt intake and the influencing factors will be determined by structured equation model (SEM). Multilevel regression analyses will be applied. Finally, the cost effectiveness of the intervention will be analyzed. DISCUSSION: This study is unique as it will recruit the individuals most vulnerable to CVD morbidity and mortality by applying the general Framingham CVD risk scoring system. Dietary salt reduction will be applied as a prioritized, community level intervention for the prevention of CVD in a developing country.Trial registrationISRCTN39416277.  相似文献

PURPOSE OF REVIEW: Diabetic dyslipidaemia, among the main factors contributing to vascular risk in type 2 diabetes, is characterized by hypertriglyceridaemia, low HDL-cholesterol and increased prevalence of small dense LDL particles. Because fibrates have positive effects on triglycerides, HDL-cholesterol and LDL particle size, they may be an appropriate treatment for diabetic dyslipidaemia. Statins have been shown to diminish significantly the risk for coronary disease in patients with type 2 diabetes, and so what are the real effects of fibrates on cardiovascular risk in type 2 diabetes? RECENT FINDINGS: Although statins reduce the incidence of coronary disease in type 2 diabetes, data from clinical trials demonstrate 'residual' cardiovascular risk in these patients treated with statins. Clinical trials with fibrates show that they are particularly effective in reducing cardiovascular risk in patients with type 2 diabetes/metabolic syndrome and in those exhibiting the lipid abnormalities typical of diabetic dyslipidaemia (elevated triglycerides, low HDL-cholesterol). SUMMARY: Data on the effects of fibrates on cardiovascular risk in diabetes were obtained from subgroup analyses. Thus far, the only study performed specifically in patients with type 2 diabetes is the angiographic Diabetes Atherosclerosis Intervention Study which demonstrated a significant reduction in progression of atherosclerosis in patients receiving fenofibrate, but it was not powered to analyse the effects of fibrates on clinical outcomes. This is why the Fenofibrate Intervention and Event Lowering in Diabetes study is needed; it will provide robust data on the ability of fibrates to reduce cardiovascular risk in patients with type 2 diabetes.  相似文献
