HEART与GRACE危险评分对急性冠脉综合征患者危险分层的对比研究

目的:探讨HEART与GRACE危险评分对急性冠脉综合症(ACS)患者主要心血管不良事件(MACE)发生的预测应用价值。方法:回顾性分析自2015年6月至2018年6月就诊于我院急诊入院的ACS患者591例,分别使用HEART与GRACE危险评分对研究对象进行危险分层(低危组,中危组,高危组),随访患者发病后90天MACE发生情况,分析不同危险分层ACS患者发病后90天MACE发生情况与评分之间的关系,并比较两种评分对ACS患者90天发生MACE事件的预测能力。结果:本研究纳入371例患者,其中男性324例(87.3%),女性47例(12.7%),年龄(58±11.70)岁;167患者(45.1%)在3个月内发生MACE。随着HEART和GRACE危险评分越高,发病90天发生MACE事件的发生率显著增加(P<0.05),HEART评分中高危组预测MACE准确性较GRACE评分高,GRACE评分低危险组预测MACE准确性较HEART评分高。HEART和GRACE评分对ACS患者预测MACE敏感性分别为76.51%,64.73%,特异性分别为96.71%,96.25%。HEART评分具有良好的预测价值,其ROC曲线下面积为0.908(95%CI 0.846~0.974),与GRACE评分ROC曲线下面积的0.801相比,差异有统计学意义(P<0.05)。结论:HEART和GRACE评分都可以应用于ACS患者的危险分层,预后评估和预测MACE发生,但HEART危险评分更可靠。     

Addition of heart score to high-sensitivity troponin T versus conventional troponin T in risk stratification of patients with chest pain at the coronary emergency rooms

Patients with chest pain have a large impact on available resources in coronary emergency rooms (CER). Clinical judgement, ECG, risk scores and biomarkers guide in risk stratification. We investigated if high-sensitivity troponin T (HsT) and the HEART Score could contribute to risk stratification at the CER. All patients with chest pain, without elevated conventional troponin levels at presentation, were included. HsT levels were determined at admission (T1), at 4–6 h (T2) and 8–10 h after symptom onset (T3). The HEART Score was calculated as risk score for the occurrence of a major adverse cardiac event (MACE). Thirty days after discharge, occurrence of MACE was registered. Eighty-nine patients were included (overall mean age 61 years (range 20–90)). At presentation, 68 patients (76 %) had a HsT below cut-off value of 14 ng/l (mean HEART Score 3.7, range 1–9). Thirty-one of these 68 patients had a HEART Score between 1–3, no MACE occurred in this group. For 3 patients (4 %) HsT levels increased above 14 ng/l. These 3 patients had a HEART Score between 4–6. The majority of patients with chest pain can be safely discharged within 4–6 h after onset of symptoms using HsT and the HEART Score. In contrast, patients with initially normal HsT but a high HEART Score need longer follow-up and repeat HsT determination.     

Indications for an early invasive strategy in NSTE-ACS patients

An early invasive strategy in patients who have acute coronary syndrome without ST-elevation (NSTE-ACS) can improve clinical outcome in high-risk subgroups. According to the current guidelines of the European Society of Cardiology (ESC), the majority of NSTE-ACS patients are classified as “high-risk”. We propose to prioritise patients with a global registry of acute coronary events (GRACE) risk score >140 over patients with isolated troponin rise or electrocardiographic changes and a GRACE risk score <140. We also acknowledge that same-day transfer for all patients at a high risk is not necessary in the Netherlands since the majority of Dutch cardiology departments are equipped with a catheterisation laboratory where diagnostic coronary angiography is routinely performed in NSTE-ACS patients. Therefore, same-day transfer should be restricted to true high-risk patients (in addition to those NSTE-ACS patients with very high-risk (VHR) criteria) in centres without coronary angiography capabilities.

     

改良HEART评分法对急诊胸痛患者分层治疗的指导价值研究

目的:研究改良HEART评分法对急诊胸痛患者分层治疗的指导价值。方法:选择我院急诊科收治的急性胸痛患者197例,根据疾病分为心源性胸痛组(n=132)和非心源性胸痛组(n=65),所有患者均行改良HEART评分和传统HEART评分,并根据评分进行危险分层,比较患者去向,建立受试者工作特征(ROC)曲线,评价HEART评分对危险分层和预后预测的价值。结果:心源性胸痛组改良HEART评分和常规HEART评分均高于非心源性胸痛组,两组改良HEART评分和常规HEART评分比较差异有统计学意义(P0.05)。改良HEART评分低危者100%未住院,中危62.71%住院,高危住院、入ICU的构成比例为73.17%、36.59%;HEART评分低危11.11%住院,中危住院、入ICU的构成比例为57.38%、6.56%,高危住院、入ICU的构成比例为68.57%、31.43%,差异有统计学意义(P0.05)。改良HEART评分用于对心源性胸痛患者分层的AUC值为0.916,敏感度为0.883,明显高于HEART评分的0.831和0.765。结论:改良HEART评分法可提高急诊胸痛患者分层的准确性,对指导患者去向和治疗价值较高。     

Chest pain in the emergency room: value of the HEART score

Background. Chest pain is one of the most common causes of presentation to the emergency room. The diagnosis of non-ST-elevation acute coronary syndrome typically causes uncertainty. Classical considerations for risk stratification are History, ECG, Age, Risk factors and Troponin (HEART). Each can be scored with zero, one or two points, depending on the extent of the abnormality. The HEART score is the sum of these five considerations. Methods. Clinical data from 122 patients referred to the emergency room for chest pain were analysed. The predictive value of the HEART score for reaching an endpoint was evaluated in 120/122 patients. Results. Twenty-nine patients reached one or more endpoints: an acute myocardial infarction was diagnosed in 16 patients, 20 underwent revascularisation and two died. The HEART score in the patients with and without an endpoint was 6.51±1.84 and 3.71±1.83 (p<0.0001) respectively. A HEART score of 0-3 points holds a risk of 2.5% for an endpoint and supports an immediate discharge. With a risk of 20.3%, a HEART score of 4-6 points implies admission for clinical observation. A HEART score ≥7points, with a risk of 72.7%, supports early invasive strategies. Conclusion. The HEART score facilitates accurate diagnostic and therapeutic choices. The HEART score is an easy, quick and reliable predictor of outcome in chest pain patients. (Neth Heart J 2008;16:191-6.)     

Consumption of diagnostic procedures and other cardiology care in chest pain patients after presentation at the emergency department

Objective

The HEART score serves risk stratification of chest pain patients at the emergency department (ED). Quicker and more solid decisions may be taken in these patients with application of this score. An analysis of medical consumption of 122 acute chest pain patients admitted before the introduction of this score may be indicative of possible savings.

Methods

Numbers of cardiology investigations and clinical admission days were counted. Charged cost of medicine was divided into three categories: ED, in-hospital, and outpatient clinic.

Results

The total cost of care was € 469,631, with an average of € 3849 per patient. Seventy-five percent of this cost was due to hospitalisation under the initial working diagnosis of acute coronary syndrome (ACS). This diagnosis was confirmed in only 29/122 (24 %) of the patients. The low-risk group (41 patients with HEART scores 0–3) included one patient with a previously scheduled CABG. In the remaining 40 patients, hospitalisation occurred in 12/40 (30 %) patients and 30/40 (75 %) patients visited the outpatient clinic. The total cost of medical care after presentation of these 40 patients was € 37,641; there were no cases where a new diagnosis of coronary artery disease was made. When medical care in this subgroup is declared redundant, major savings on national medical care budgets could be made.

Conclusion

If the HEART score were to be routinely applied, diagnostic pathways could be shortened and costs reduced, in particular in low-risk patients.     

Performance of a simplified HEART score and HEART-GP score for evaluating chest pain in urgent primary care

BackgroundChest pain is a common symptom in urgent primary care. The distinction between urgent and non-urgent causes can be challenging. A modified version of the HEART score, in which troponin is omitted (‘simplified HEART’) or replaced by the so-called ‘sense of alarm’ (HEART-GP), may aid in risk stratification.MethodThis study involved a retrospective, observational cohort of consecutive patients evaluated for chest pain at a large-scale, out-of-hours, regional primary care facility in the Netherlands, with 6‑week follow-up for major adverse cardiac events (MACEs). The outcome of interest is diagnostic accuracy, including positive predictive value (PPV) and negative predictive value (NPV).ResultsWe included 664 patients; MACEs occurred in 4.8% (n = 32). For  simplified HEART and HEART-GP, we found C‑statistics of 0.86 (95% confidence interval (CI) 0.80–0.91) and 0.90 (95% CI 0.85–0.95), respectively. Optimal diagnostic accuracy was found for a simplified HEART score ≥2 (PPV 9%, NPV 99.7%), HEART-GP score ≥3 (PPV 11%, NPV 99.7%) and HEART-GP score ≥4 (PPV 16%, NPV 99.4%). Physicians referred 157 patients (23.6%) and missed 6 MACEs. A simplified HEART score ≥2 would have picked up 5 cases, at the expense of 332 referrals (50.0%, p < 0.001). A HEART-GP score of ≥3 and ≥4 would have detected 5 and 3 MACEs and led to 293 (44.1%, p < 0.001) and 186 (28.0%, p = 0.18) referrals, respectively.ConclusionHEART-score modifications including the physicians’ ‘sense of alarm’ may be used as a risk stratification tool for chest pain in primary care in the absence of routine access to troponin assays. Further validation is warranted.Supplementary InformationThe online version of this article (10.1007/s12471-020-01529-4) contains supplementary material, which is available to authorized users.     

Patients who do not complete cardiac rehabilitation have an increased risk of cardiovascular events during long-term follow-up

Background

Cardiac rehabilitation (CR) has favourable effects on cardiovascular mortality and morbidity. Therefore, it might reasonable to expect that incomplete CR participation will result in suboptimal patient outcomes.

Methods

We studied the 914 post-acute coronary syndrome patients who participated in the OPTImal CArdiac REhabilitation (OPTICARE) trial. They all started a ‘standard’ CR programme, with physical exercises (group sessions) twice a week for 12 weeks. Incomplete CR was defined as participation in <75% of the scheduled exercise sessions. Patients were followed-up for 2.7 years, and the incidence of cardiac events was recorded. Major adverse cardiac events (MACE) included all-cause mortality, non-fatal myocardial infarction and coronary revascularisation.

Results

A total of 142 (16%) patients had incomplete CR. They had a higher incidence of MACE than their counterparts who completed CR (11.3% versus 3.8%, adjusted hazard ratio [aHR] 2.86 and 95% confidence interval [CI] 1.47–5.26). Furthermore, the incidence of any cardiac event, including MACE and coronary revascularisation, was higher (20.4% versus 11.0%, aHR 1.54; 95% CI 0.98–2.44). Patients with incomplete CR were more often persistent smokers than those who completed CR (31.7% versus 11.5%), but clinical characteristics were similar otherwise.

Conclusion

Post-ACS patients who did not complete a ‘standard’ 12-week CR programme had a higher incidence of adverse cardiac events during long-term follow-up than those who completed the programme. Since CR is proven beneficial, further research is needed to understand the reasons why patients terminate prematurely.

     

Coronary CT angiography for suspected acute coronary syndrome: sex-associated differences

AimThe optimal diagnostic test in the work-up of suspected acute coronary syndrome (ACS) may differ between men and women. The aim of this study was to compare sex-associated differences between using a diagnostic strategy including early coronary computed tomography angiography (CCTA) and standard of care (SOC).MethodsIn total, 500 patients who presented with symptoms suggestive of ACS at the emergency department were randomised between a diagnostic strategy supplemented with early CCTA and SOC.ResultsWomen were generally older than men (mean ± standard deviation 56 ± 10 vs 53 ± 10 years, p < 0.01) and were less often admitted to hospital (33% vs 44%, p = 0.02). Obstructive coronary artery disease on CCTA (> 50% luminal narrowing) was less frequently seen in women (14% vs 26%, p = 0.02), and ACS was diagnosed less often in women (5% vs 10%, p = 0.03). Women underwent less outpatient testing when early CCTA was used in the emergency department evaluation of suspected ACS (p = 0.008).ConclusionWomen had a lower incidence of obstructive CAD on CCTA and were less often admitted to hospital than men. They were subjected to less outpatient testing when early CCTA was used in the emergency department evaluation of suspected ACS.Supplementary InformationThe online version of this article (10.1007/s12471-021-01607-1) contains supplementary material, which is available to authorized users.     

Serum tryptase detected during acute coronary syndrome is significantly related to the development of major adverse cardiovascular events after 2?years

Background

One of the greatest challenges in cardiovascular medicine is to define the best tools for performing an accurate risk stratification for the recurrence of ischemic events in acute coronary syndrome (ACS) patients.

Methods

We followed 65 ACS patients enrolled in a previous pilot study for 2 years after being discharged, focusing on the occurrence of major adverse cardiovascular events (MACE).The relationship between serum tryptase levels on admission, SYNergy between percutaneous coronary intervention with the TAXUS drug-eluting stent and the cardiac surgery score (SX-score), cardiovascular complexity and MACE at 2 years follow-up were analyzed.

Results

The ACS population was divided in two groups: patients with MACE (n = 23) and patients without MACE (n = 42).The tryptase measurement at admission (T0) and at discharge (T3) and SX-score were higher in patients who experienced MACE than in those without (p = 0.0001, p < 0.0001 and p = 0.006, respectively). Conversely, we found no significant association between MACE and C-reactive protein (CRP), and between MACE and maximum level of high-sensitivity troponin (hs-Tn) values.Among all patients with MACE, 96% belonged to the group that presented with cardiovascular complexity at the beginning of ACS index admission (p < 0.0001).The predictive accuracy of serum tryptase for MACE at follow up set at the cut-off point of 4.95 ng/ml at T0 and of 5.2 ng/ml at T3. Interestingly, patients with both the above cut-off tryptase values at T0 and at T3 presented a 1320% increase in the odds of developing MACE (p < 0.0001).

Conclusion

In ACS patients, serum tryptase measured during index admission is significantly correlated to the development of MACE up to 2 years, demonstrating a possible long-term prognostic role of this biomarker.

PREVENTION-ACHD: PRospEctiVE study on implaNTable cardioverter-defibrillator therapy and suddeN cardiac death in Adults with Congenital Heart Disease; Rationale and Design

Background

Many adult congenital heart disease (ACHD) patients are at risk of sudden cardiac death (SCD). An implantable cardioverter-defibrillator (ICD) may prevent SCD, but the evidence for primary prevention indications is still unsatisfactory.

Study Design

PREVENTION-ACHD is a prospective study with which we aim to prospectively validate a new risk score model for primary prevention of SCD in ACHD patients, as well as the currently existing guideline recommendations. Patients are screened using a novel risk score to predict SCD as well as current ICD indications according to an international Consensus Statement. Patients are followed up for two years. The primary endpoint is the occurrence of SCD and sustained ventricular arrhythmias. The Study was registered at ClinicalTrials.gov (NCT03957824).

Conclusion

PREVENTION-ACHD is the first prospective study on SCD in ACHD patients. In the light of a growing and aging population of patients with more severe congenital heart defects, more robust clinical evidence on primary prevention of SCD is urgently needed.

     

Long-term follow-up after bypass surgery or coronary stenting in elderly with multivessel disease

Background

We sought to compare long-term follow-up of coronary artery bypass grafting (CABG) with percutaneous coronary intervention (PCI) in elderly patients with left main or multivessel disease, hypothesising that completeness of revascularisation and severity of coronary artery disease are predictors of adverse outcomes.

Methods

Patients aged ≥75 years with multivessel disease or left main disease who underwent PCI or CABG between 2012–2016 were included in this retrospective cohort study. Baseline characteristics from the index procedure were collected. Severity of coronary artery disease and completeness of revascularisation were assessed. Primary outcome was all-cause mortality, in addition we captured major adverse cardiac and cerebral events, bleedings, recurrent angina and new onset atrial fibrillation.

Results

A total of 597 patients were included. Median follow-up was 4 years (interquartile range 2.8–5.3 years). At baseline, patients in the PCI group more often had a previous medical history of CABG and more frequently underwent an urgent procedure compared with patients in the CABG group. Mortality at 5‑year follow-up was significantly higher in patients who underwent PCI compared with CABG (39.9% vs 25.4%, p < 0.001). Furthermore, acute coronary syndrome (ACS), repeat revascularisation and recurrent angina occurred more frequently after PCI, while occurrence of bleedings and new onset atrial fibrillation were more frequent after CABG. Neither completeness of revascularisation nor severity of coronary artery disease was a predictor for any of the outcomes.

Conclusion

Long-term mortality was higher in elderly patients with multivessel disease undergoing PCI compared with CABG. In addition, patients undergoing PCI had a higher risk of ACS, repeat revascularisation and recurrent angina.

     

The 1‑year safety and efficacy outcomes of Absorb bioresorbable vascular scaffolds for coronary artery disease treatment in diabetes mellitus patients: the ABSORB DM Benelux study

Background

Diabetes mellitus (DM) patients show higher rates of repeat revascularisation even in the era of modern drug-eluting stents (DES). The concept of bioresorbable scaffolds is becoming captivating, as it might allow for repeat interventions, prolonging the time span during which patients can be treated by percutaneous coronary intervention (PCI).

Aims

We intend to evaluate the short- and long-term safety and efficacy of Absorb bioresorbable vascular scaffolds (Absorb BVS) in the treatment of coronary artery disease (CAD) in DM patients for any indication.

Methods

The ABSORB DM Benelux is an international prospective study in DM patients who have undergone PCI with ≥1 Absorb BVS. Major adverse cardiac events (MACE) at 1 year was the primary endpoint, defined as a composite of all-cause death, any myocardial infarction (MI) and ischaemia-driven target vessel revascularisation (TVR). Secondary endpoints were target lesion failure (TLF) and definite or probable scaffold thrombosis (ScT).

Results

Between April 2015 and March 2017, 150 DM patients and 188 non-complex lesions were treated. Device implantation was successful in 100%. MACE occurred in 14 (9.5%) patients, with all-cause death occurring in 4 (2.7%), any MI in 6 (4.1%) and ischaemia-driven TVR in 7 (4.8%) respectively. TLF was reported in 11 (7.5%). Definite and probable ScT was observed in 2 (1.4%).

Conclusion

Absorb BVS for treatment of anatomically low-risk patients with DM show acceptable safety and efficacy outcomes at 1 year. If these promising results are confirmed after a longer follow-up period, new-generation bioresorbable scaffolds combined with refinement of implantation techniques might open new horizons for CAD treatment in DM patients.

     

Superiority of total white blood cell count over other leukocyte differentials for predicting long-term outcomes in patients with non-ST elevation acute coronary syndrome

Abstract

Context: Leukocytes have been found to be the predictor of outcome following acute coronary syndrome (ACS).

Objective: We sought to determine the relationship between leukocyte differentials and developing major adverse cardiac events (MACE) in patients with non-ST elevation ACS (NSTE-ACS).

Materials and methods: A total of 490 consecutive patients were enrolled, and MACE incidence was evaluated at long-term follow-up period.

Results: Total white blood cell (WBC) was higher in subjects occurring MACE. Moreover, elevated total WBC, ≥7.5?×?10³/µL, independently predicted MACE.

Discussion and conclusion: Elevated admission total WBC can predict long-term MACE in NSTE-ACS patients better than other differentials.

Aldehyde dehydrogenase 2 Glu504Lys variant predicts a worse prognosis of acute coronary syndrome patients

Aldehyde dehydrogenase 2 (ALDH2) Glu504Lys variant was an independent risk factor for acute coronary syndrome (ACS). However, there are lacking researches about the relationship between the variant and prognosis of ACS. In the prospective study, 377 ACS patients were grouped into the wild‐type (*1/*1) and the mutation (*2/*2 + *1/*2) groups according to genotype detection. Compared with the wild‐type group, incidences of major adverse cardiac events (MACE) and cardiac death were both higher in the mutation group (9.2% vs 21.0%, P = .002; 5.2% vs 12.2%, P = .026); the MACE‐free and the cardiac‐death‐free cumulative survival rates were obviously lower in the mutation group. Moreover, the mutant genotypes were associated with significantly increased risk of MACE and cardiac death (HR 2.443, 95%CI: 1.390‐4.296, P = .002; HR 2.727, 95%CI: 1.303‐5.708, P = .008). These results suggested that ALDH2 Glu504Lys variant could predict a worse prognosis of ACS patients.     

Development and first results of a dedicated chronic total occlusion programme

Objective

To describe the development and first results of a dedicated chronic total occlusion (CTO) programme in a tertiary medical centre.

Background

Because of the complexity and the increased risk of complications during percutaneous coronary intervention (PCI) for CTO, it is essential that less experienced and evolving CTO centres perform regular quality analyses.

Methods

We therefore performed analyses to describe the results during the first 3 years of a dedicated CTO programme at a high-volume PCI centre. In addition, we discuss the strategies employed to develop such a programme.

Results

A total of 179 consecutive patients undergoing 187 CTO procedures were included in the study. The complexity of the CTO lesions increased from a mean J‑CTO (Japanese Multicentre CTO Registry) score of 1.3 in 2015 to 2.1 in 2017. In the majority of cases, the antegrade wire escalation technique was performed. Final technical success rate was 78.5% in 175 patients with a single CTO and 80.2% of all 187 CTO procedures. No peri-procedural or in-hospital deaths occurred. One peri-procedural myocardial infarction occurred. Cardiac tamponade occurred in 2 cases, both managed by pericardiocentesis. No urgent cardiac surgery was necessary. Survival and revascularisation rates at 30 days and 1 year were excellent.

Conclusion

Following initiation of a dedicated CTO programme, using up-to-date techniques and strategies, procedural and clinical outcome were comparable with current standards in established centres.

     

Telemonitoring with an implantable loop recorder in outpatient heart failure care

Introduction

In the care of heart failure patients, telemonitoring is receiving growing attention. The main purpose of this study was to determine the effect of continuous telemonitoring with an implantable loop recorder (ILR, Reveal XT), a novel strategy in the management of stable heart failure patients without a cardiac implantable device. Furthermore, little is known about the incidence of subclinical arrhythmias in this specific group of patients.

Materials and Methods

Stable heart failure patients, New York Heart Association Class II and III, without recent hospitalisation or upcoming intervention, were included. After implantation of the ILR there was regular contact with the research nurse on a pre-specified basis. Clinic visits and telephonic interviews were alternated for a minimum of 1 year. Parallel visits to their treating physician continued according to standard care. The treating physician was blinded for the ILR findings, accept for pre-specified, significant arrhythmic events.

Results

Thirty patients were included and followed for a median duration of 12 months. In 13 patients, data from the loop recorder led to therapeutic changes. One patient received a pacemaker. Eight patients developed atrial fibrillation, all subclinical, with a mean burden of 65.8 ± 173.2 min/day.

Conclusion

The use of an ILR could potentially impact patient management. Additional study is needed in different patient populations (e. g. higher risk groups) to assess if an ILR could also impact on endpoints such as heart failure hospitalisation.

     

Soluble urokinase plasminogen activator receptor as a long-term prognostic biomarker in acute coronary syndromes

Abstract

Purpose: The aim of our study was to analyse the long-term prognostic value of soluble urokinase plasminogen activator receptor (suPAR) in the setting of an acute coronary syndrome (ACS).

Methods: We included 340 patients with an ACS who underwent coronary angiography and plasma suPAR concentration was measured. Patients were classified into low suPAR concentrations (<2.6?ng/mL) and high suPAR concentrations (≥2.6?ng/mL) and long-term events were evaluated. suPAR prognostic value was assessed beyond a clinical model that included age, GRACE score, estimated glomerular filtration rate, cardiac troponin-I peak and left ventricular ejection fraction <40%.

Results: Higher suPAR concentrations were associated with an increased prevalence of cardiovascular risk factors. After multivariate adjustment, suPAR ≥2.6?ng/mL were independently associated with an increased risk of all-cause death (HR 2.3; 95%CI 1.2–4.4; p?=?.017), major adverse cardiovascular events (MACE) (HR 1.7; 95%CI 1.1–2.5; p?=?.020) and heart failure (HR 4.1; 95%CI 1.3–12.6; p?=?.015), but not with myocardial infarction. For long-term all-cause death significant improvement of reclassification and discrimination were seen after addition of suPAR to a clinical model.

Conclusions: In the setting of an ACS, suPAR is associated with long-term all-cause death, heart failure and MACE, and provides incremental prognostic value beyond traditional risks factors.
