Comparison of the sugar intake of 1,158 men believed to be free of ischaemic heart disease failed to establish any real difference in intake when compared with 170 men with confirmed or possible ischaemic heart disease. In neither group was mere any significant correlation between sugar intake and serum cholesterol, white blood cell count, haemoglobin, E.S.R., β-lipoprotein, or uric add; nor was there any correlation between total sugar intake and weight gain after the age of 25 years.These results suggest that considerably more confirmation is required before acceptance of Yudkm''s hypothesis that high sugar intake is the chief dietary factor causing ischaemic heart disease. 相似文献

Background
Ischemic heart disease (IHD) mortality has been on the decline in the United States for decades. However, declines in IHD mortality have been slower in certain groups, including young women and black individuals.Hypothesis
Trends in IHD vary by age, sex, and race in New York City (NYC). Young female minorities are a vulnerable group that may warrant renewed efforts to reduce IHD.Methods
IHD mortality trends were assessed in NYC 1980–2008. NYC Vital Statistics data were obtained for analysis. Age-specific IHD mortality rates and confidence bounds were estimated. Trends in IHD mortality were compared by age and race/ethnicity using linear regression of log-transformed mortality rates. Rates and trends in IHD mortality rates were compared between subgroups defined by age, sex and race/ethnicity.Results
The decline in IHD mortality rates slowed in 1999 among individuals aged 35–54 years but not ≥55. IHD mortality rates were higher among young men than women age 35–54, but annual declines in IHD mortality were slower for women. Black women age 35–54 had higher IHD mortality rates and slower declines in IHD mortality than women of other race/ethnicity groups. IHD mortality trends were similar in black and white men age 35–54.Conclusions
The decline in IHD mortality rates has slowed in recent years among younger, but not older, individuals in NYC. There was an association between sex and race/ethnicity on IHD mortality rates and trends. Young black women may benefit from targeted medical and public health interventions to reduce IHD mortality. 相似文献8.

Of 160 patients who survived ventricular fibrillation complicating acute ischaemic heart disease, 80 had had a clinically mild coronary attack. Most of the long-term survivors had ventricular fibrillation within 24 hours of the onset of symptoms. The longterm prognosis of the survivors was similar to that of patients whose myocardial infarction was not complicated by ventricular fibrillation. Those patients who survived ventricular fibrillation which occurred within four hours of the onset of symptoms were younger, usually had had a mild coronary attack, and had the most favourable longterm prognosis. The number of episodes of ventricular fibrillation did not affect adversely the long-term prognosis. Of those who at the time of review were eligible to work, 86% were fit to work and 68% were actually at work. 相似文献

Data are presented on the incidence of ischaemic (coronary) heart disease and duodenal ulcer among the several thousand male medical practitioners aged 35–64 holding immediate sickness benefit policies with the Medical Sickness Annuity and Life Assurance Society Limited. Three periods are considered: 1947–50, 1957–60, and 1961–5.The incidence of first clinical episodes of ischaemic heart disease in the doctors altered little between 1947–50 and 1957–60 but increased in 1961–5. Comparison of the late 1940s with the early 1960s shows a 60% rise of incidence at ages 45–54 but little change at other ages. Cases first presenting as “sudden” death increased between 1947–50 and 1961–5 by 111% at 45–54, and again changed little at 55–64. In two other occupational groups that have been studied—bus conductors and insurance salesmen—the increase of incidence was greater than for the doctors at 45–54 and it occurred also over 55 years of age. The increase from 1947–50 to 1961–5 in mortality during all episodes of ischaemic heart disease was the same in the doctors as in the male population of England and Wales at 45–54, but at 55–64 it was less.The results in the doctors are not due to alterations over the period in length of sickness absence, or underwriting policy, or of the nomenclature used on the certificates.Well-documented changes in the smoking habits of doctors may be partly responsible for what appears to have been a relatively favourable experience of ischaemic heart disease from 1947–50 to 1961–5, especially at ages 55–64.Incidence of duodenal ulcer at ages 35–64 declined steadily in this population of doctors from 1947–50 to 1961–5. The decline is very likely to be real. 相似文献

A trial is reported of the effects of giving clofibrate to prevent progression of pre-existing ischaemic heart disease. There were two groups randomly distributed between clofibrate (350 patients) and placebo (367 patients) regimens. The trial lasted about six years and was conducted in 19 hospitals in Scotland. The criteria of acceptance into the trial were precise and were monitored by one observer. The standards of diagnosis of events were defined and all protocols and electrocardiograms were read blind by one observer.Three categories of patients were admissible to the trial: (1) patients with one myocardial infarction (W.H.O. E.C.G. criteria) between 8 and 16 weeks before the start of the trial; (2) patients with angina of a duration of 3 to 24 months, provided their E.C.G. showed signs of myocardial ischaemia at rest or after exercise; and (3) patients with one recent myocardial infarction and pre-existing angina as defined above.There were fewer deaths in patients with angina (categories 2 and 3 above) treated with clofibrate than in those on placebo. The mortality in the former group was reduced by 62%, and this is a statistically significant difference. Clofibrate did not have any statistically significant effect in reducing the rate of non-fatal infarction in patients with angina or in those with myocardial infarction and pre-existing angina, though a beneficial trend was evident when both subgroups were combined (a 44% reduction compared with the placebo group). There was a significant reduction in all events (fatal and non-fatal) in patients with angina (“all anginas”) in the clofibrate-treated group; the rate was reduced by 53%.Clofibrate did not alter the overall mortality or morbidity rates in patients admitted to the trial with recent myocardial infarction without preceding angina of more than three months'' duration. In one subgroup there was a statistically significant adverse effect in the clofibrate-treated group. The lack of any overall effect in patients with myocardial infarction might be related to the unexpectedly low mortality rate (2·97%) in the placebo group; it is usually in the region of 4-9% per annum after first myocardial infarction.In patients categorized as “all anginas” there was significant reduction in events whether the initial serum cholesterol level was high (greater than 260 mg/100 ml) or normal. Clofibrate seemed to have a small but not significant beneficial effect in patients with myocardial infarction with initially high serum cholesterol levels, but was of no value in those with initially normal serum cholesterol levels. There was no significant relationship between the response or lack of response of serum cholesterol to clofibrate and the incidence of events either in patients with angina or in those with infarction.The main conclusion of this trial is that clofibrate had a beneficial effect in reducing mortality and, to a lesser extent, morbidity in patients who presented with angina (“all anginas”). This effect was independent of initial serum cholesterol levels or the extent to which serum cholesterol was lowered. The drug had no significant overall effect on prognosis in patients with myocardial infarction alone. 相似文献

The frequency and nature of abnormalities of serum lipoproteins have been studied, using quantitative techniques, in 143 patients with ischaemic heart disease (I.H.D.). Rigorous selection criteria were used. The findings were related to the distribution of lipoprotein concentrations in a carefully screened control population. Hyperlipoproteinaemia occurred in 55% of patients and in 11 out of 15 patients aged less than 40 years. Raised triglyceride and cholesterol concentrations in very low density lipoprotein were the most frequent abnormalities followed by raised cholesterol content of low density lipoprotein. In young patients high density lipoprotein levels were subnormal. Hyperlipoproteinaemia of W.H.O. types IIa, IIb, III, IV, and V all seemed to be over-represented in I.H.D. I.H.D. patients with type IIa, IIb, and IV abnormalities were all significantly younger than I.H.D. patients with normal lipoprotein levels. 相似文献

Background
With economic development and population aging, ischaemic heart disease (IHD) is becoming a leading cause of mortality with widening inequalities in China. To forewarn the trends in China we projected IHD trends in the most economically developed part of China, i.e., Hong Kong.Methods
Based on sex-specific IHD mortality rates from 1976 to 2005, we projected mortality rates by neighborhood-level socio-economic position (i.e., low- or high-income groups) to 2020 in Hong Kong using Poisson age-period-cohort models with autoregressive priors.Results
In the low-income group, age-standardized IHD mortality rates among women declined from 33.3 deaths in 1976–1980 to 19.7 per 100,000 in 2016–2020 (from 55.5 deaths to 34.2 per 100,000 among men). The rates in the high-income group were initially higher in both sexes, particularly among men, but this had reversed by the end of the study periods. The rates declined faster for the high-income group than for the low-income group in both sexes. The rates were projected to decline faster in the high-income group, such that by the end of the projection period the high-income group would have lower IHD mortality rates, particularly for women. Birth cohort effects varied with sex, with a marked upturn in IHD mortality around 1945, i.e., for the first generation of men to grow up in a more economically developed environment. There was no such upturn in women. Birth cohort effects were the main drivers of change in IHD mortality rates.Conclusion
IHD mortality rates are declining in Hong Kong and are projected to continue to do so, even taking into account greater vulnerability for the first generation of men born into a more developed environment. At the same time social disparities in IHD have reversed and are widening, partly as a result of a cohort effect, with corresponding implications for prevention. 相似文献19.

ObjectivePatients with inflammatory bowel disease (IBD) demonstrate an inflammatory response which bears some similarities to that seen in ischaemic heart disease (IHD). The nature of the association of IBD with IHD is uncertain. We aimed to define the extent and direction of that association.DesignThis retrospective cohort study examined records from patients aged ≥ 15 years with IBD from 1987–2009 (n = 19163) who were age and gender matched with patients without IBD (n = 75735) using the General Practice Research Database. The primary outcome was the hazard ratio for IHD.ResultsA higher proportion of IBD patients had a recorded diagnosis of IHD ever, 2220 (11.6%) compared with 6504 (8.6%) of controls. However, the majority (4494, 51.5%) developed IHD prior to IBD diagnosis (1404 (63.2%) of IBD cases and 3090 (47.5%) of controls). There was increased IHD incidence in the first year after IBD diagnosis. Mean age at IHD diagnosis was statistically similar across all IBD groups apart from for those with Ulcerative Colitis (UC) who were slightly younger at diagnosis of angina compared to controls (64.5y vs. 67.0y, p = 0.008) and coronary heart disease (65.7y vs.67.9y, p = 0.015). Of those developing IHD following IBD diagnosis, UC patients were at higher risk of IHD (unadjusted HR 1.3 (95% CI 1.1–1.5), p<0.001) or MI (unadjusted HR 1.4 (95% CI 1.1–1.6), p = 0.004).ConclusionAlthough IHD prevalence was higher in IBD patients, most IHD diagnoses predated the diagnosis of IBD. This implies a more complex relationship than previously proposed between the inflammatory responses associated with IHD and IBD, and alternative models should be considered. 相似文献
