STEMI or non-STEMI: that is the question

Acute coronary syndromes are usually classified on the basis of the presence or absence of ST elevation on the ECG: ST-elevation myocardial infarction or non-ST-elevation myocardial infarction (NSTEMI)patients with acute myocardial infarction (AMI) need immediate therapy, without unnecessary delay and primary percutaneous coronary intervention (PPCI) should preferably be performed within 90 min after first medical contact. However, in AMI patients without ST-segment elevation (pre) hospital triage for immediate transfer to the catheterisation laboratory may be difficult. Moreover, initial diagnosis and risk stratification take place at busy emergency departments and chest pain units with additional risk of ‘PPCI delay’. Optimal timing of angiography and revascularisation remains a challenge. We describe a patient with NSTEMI who was scheduled for early coronary angiography within 24 h but retrospectively should have been sent to the cath lab immediately because he had a significant amount of myocardium at risk, undetected by non-invasive parameters.     

Conditions mimicking acute ST-segment elevation myocardial infarction in patients referred for primary percutaneous coronary intervention

Background/Objectives. A rapid diagnosis of ST-segment elevation myocardial infarction (STEMI) is mandatory for optimal treatment. However, a small proportion of patients with suspected STEMI suffer from other conditions. Although case reports have described these conditions, a contemporary systematic analysis is lacking. We report the incidence, clinical characteristics and outcome of patients with suspected STEMI referred for primary percutaneous coronary intervention (PCI) with a final diagnosis other than STEMI. Methods. From January 2004 to July 2005, 820 consecutive patients were included with suspected STEMI who were referred for primary PCI to a university medical centre, based on a predefined protocol. Clinical characteristics, final diagnosis and outcome were obtained from patient charts and databases. Results. In 19 patients (2.3%), a final diagnosis other than myocardial infarction was established: coronary aneurysm (n=1), (myo)pericarditis (n=5), cardiomyopathy (n=2), Brugada syndrome (n=1), aortic stenosis (n=1), aortic dissection (n=3), subarachnoidal haemorrhage (n=2), pneumonia (n=1), chronic obstructive pulmonary disease (n=1), mediastinal tumour (n=1), and peritonitis after recent abdominal surgery (n=1). These patients less often reported previous symptoms of angina (p<0.001), smoking (p<0.05) and a positive family history of cardiovascular diseases (p<0.05) than STEMI patients. Mortality at 30 days was 16%. Conclusion. A 2.3% incidence of conditions mimicking STEMI was found in patients referred for primary PCI. A high clinical suspicion of conditions mimicking STEMI remains necessary. (Neth Heart J 2008;16:325-31.)

Thrombus Aspiration during Percutaneous coronary intervention in Acute non-ST-elevation myocardial infarction Study (TAPAS II)-Study design

Background and Objective. The Thrombus Aspiration during Percutaneous coronary intervention in Acute myocardial infarction Study (TAPAS) has shown that thrombus aspiration improves myocardial perfusion and clinical outcome compared with conventional primary percutaneous coronary intervention (PCI) in patients with ST-segment-elevation myocardial infarction. Impaired myocardial perfusion due to spontaneous or angioplasty-induced embolisation of atherothrombotic material also occurs in patients with non-ST-elevation myocardial infarction (NSTEMI). The aim of this study is to determine whether thrombus aspiration before stent implantation will result in improved myocardial perfusion in patients with NSTEMI compared with conventional PCI. Study design. The study is a single-centre, prospective, randomised trial with blinded evaluation of endpoints. The planned inclusion is 540 patients with acute NSTEMI who are candidates for urgent PCI. Patients are randomised to treatment with manual thrombus aspiration or to conventional PCI. The primary endpoint is the incidence of myocardial blush grade 3 after PCI. Secondary endpoints are coronary angiographic, histopathological, enzymatic, electrocardiographic and clinical outcomes including major adverse events at 30 days and one year. Implications. If thrombus aspiration leads to significant improvement of myocardial perfusion in patients with acute NSTEMI it may become part of the standard interventional approach.

Relationship between time of day and periprocedural myocardial infarction after elective angioplasty

Objectives: To test if the time of day significantly influences the occurrence of type 4A myocardial infarction in elective patients undergoing percutaneous coronary intervention (PCI).

Background: Recent studies have suggested an influence of circadian rhythms on myocardial infarction size and mortality among patients with ST-elevation myocardial infarction. The aim of the study is to investigate whether periprocedural myocardial infarction (PMI) is influenced by the time of day in elective patients undergoing PCI.

Methods: All consecutive patients undergoing elective PCI between 2007 and 2011 at our institutions with known post-interventional troponin were retrospectively included. Patients (n?=?1021) were divided into two groups according to the starting time of the PCI: the morning group (n?=?651) between 07:00 and 11:59, and the afternoon group (n?=?370) between 12:00 and 18:59. Baseline and procedural characteristics as well as clinical outcome defined as the occurrence of PMI were compared between groups. In order to limit selection bias, all analyses were equally performed in 308 pairs using propensity score (PS) matching.

Results: In the overall population, the rate of PMI was statistically lower in the morning group compared to the afternoon group (20% vs. 30%, p?<?0.001). This difference remained statistically significant after PS-matching (21% vs. 29%, p?=?0.03). Multivariate analysis shows that being treated in the afternoon independently increases the risk for PMI with an odds ratio of 2.0 (95%CI: 1.1–3.4; p?=?0.02).

Conclusions: This observational PS-matched study suggests that the timing of an elective PCI influences the rate of PMI.

Long-term ischaemic and bleeding outcomes after primary percutaneous coronary intervention for ST-elevation myocardial infarction in the elderly

Background

The population is ageing rapidly and the proportion of patients aged ≥ 80 years undergoing primary percutaneous coronary intervention (PCI) is rising, but clinical trials have primarily been performed in younger patients.

Methods

Patients undergoing primary PCI between 2003 and 2008 were subdivided into 3 groups: < 60, 60-79, and ≥ 80 years. Endpoints at 3-year follow-up included all-cause mortality, recurrent myocardial infarction (reMI), stent thrombosis, target lesion revascularisation (TLR), bleeding (BARC bleeding ≥ 3), stroke, and major adverse cardiovascular events (MACE, a composite of cardiac mortality, reMI, stroke and TLR).

Results

2002 patients with ST-segment elevation myocardial infarction (STEMI) were included, 885 (44.2 %) aged < 60, 921 (46.0 %) 60–79, and 196 (9.7 %) ≥ 80 years. Comorbidities such as diabetes mellitus, prior stroke, malignant disease, anaemia, and chronic kidney disease were more prevalent in patients ≥ 80 years. The incidence of both ischaemic and bleeding events strongly increased with age. Age ≥ 80 years was an independent predictor of mortality (HR 2.56, 95 % CI1.69–3.87, p < 0.001), a borderline non-significant predictor of overall bleeding (HR 1.38, 95 %CI 0.95–2.00, p = 0.088), and a significant predictor of non-access site bleeding (HR 2.26, 95 %CI 1.46–3.51, p < 0.001).

Conclusion

Patients ≥ 80 years experienced high rates of ischaemic and bleeding complications; especially in this high-risk patient group individualised therapy is needed to optimise clinical outcomes.

血小板平均体积与老年急性ST段抬高型心肌梗死患者并发心力衰竭的 相关性分析

目的:探讨血小板平均体积(MPV)与老年急性ST段抬高型心肌梗死(STEMI)患者住院期间并发心力衰竭(HF)的相关性。方法:收集我院收治的172例老年STEMI患者,按照住院期间是否发生HF分为HF组(n=55例)和非HF组(n=117例),以患者MPV四分位分四组,比较以上各组之间相关指标的差异,用Logistic回归方程分析MVP与患者HF发生的关系。结果:HF组与非HF组在吸烟、发病至入院时间、前壁梗死、血清B型脑钠肽(BNP)、肌钙蛋白I(c Tn I)、左室射血分数(LVEF)、MVP存在统计学差异(P0.05),HF组MVP水平高于非HF组(P0.05);MVP四分位分组之间的心功能指标LVEF和血清BNP、HF发生率存在统计学差异(P0.05),MVP的第四四分位组(Q4组)的HF发生率高于第一分位组及第二四分位组(Q1及Q2组);多因素Logistic回归方程分析显示高水平MPV是老年STEMI患者近期发生心力衰竭的独立危险因素(P0.05);MVP四分位分组中,从Q1组到Q4组发生HF的风险值(OR)依次增高,且Q3及Q4组的OR值具有统计学意义(P0.05)。结论:高水平MPV与老年STEMI患者住院期间HF发生密切相关,可能是其发生的独立危险因素,应当引起临床关注。     

The relation between myocardial blush grade and myocardial contrast echocardiography: which one is a better predictor of myocardial damage?

Background. Myocardial blush grade (MBG) and myocardial contrast echocardiography (MCE) are both indices for myocardial perfusion in patients with ST-elevation acute myocardial infarction (STEMI). We aimed to compare MBG with MCE in the infarct-related artery segment for assessing infarct size in patients with STEMI treated with primary percutaneous coronary intervention (PCI).Methods. 43 patients underwent successful (postprocedural TIMI flow 3) primary PCI for STEMI. MBG was assessed at the end of the PCI procedure and MCE was assessed 1.7±1.8 days after PCI. Enzymatic infarct size was estimated by measurementof enzyme activities by using lactate dehydrogenase (LDH) as the referenceenzyme. Cumulative enzyme release (LDHQ₄₈) from at least five serial measurements up to 48 hours after symptom onset was calculated. Also peak creatine kinase, CK-MB and peak LDH were measured.Results. MBG 0/1, 2 and 3 were observed in 14, 12 and 17 patients, respectively, and was compared with tertiles of MCE. We found a parallel correlation between both MBG and MCE and LDHQ₄₈. However, there was no correlation between MCE and MBG. Patients with both normal MCE and a normal MBG had least myocardial damage and those with both impaired MCE and an impaired MBG had most myocardial damage.Conclusion. Both MBG and MCE are good predictors of infarct size in STEMI patients treated with PCI. However, these markers are not mutually related, possibly due to time-related changes in myocardial perfusion. Combining these two markers may yield a more accurate prediction of final myocardial damage. (Neth Heart J 2010;18:25-30.)     

急性ST段抬高型心肌梗死介入手术时间窗与血清FGF21水平的相关性

摘要 目的：探讨急性ST段抬高型心肌梗死介入手术时间窗与血清成纤维细胞生长因子21（FGF21）水平的相关性。方法：选择本院2019年1月-2021年1月收治的急性ST段抬高型心肌梗死患者120例作为研究对象,根据随机1：1抽签法把患者分为研究组与对照组各60例。所有患者都给予急诊经皮冠脉介入手术治疗,对照组在发病后7-12 h进行介入治疗,研究组在发病后≤6 h进行介入治疗,检测、记录血清FGF21表达变化情况并进行相关性分析。结果：两组治疗后1周的血清心肌肌钙蛋白T（cTnT）、心肌肌钙蛋白Ⅰ（cTnⅠ）含量低于治疗前,研究组低于对照组（P<0.05）。两组治疗后1周的血清FGF21水平高于治疗前,研究组高于对照组（P<0.05）。治疗后随访6个月,研究组的心律失常、心力衰竭、心绞痛、心源性休克等不良心血管事件发生率为3.3 %,低于对照组的26.7 %（P<0.05）。在两组120例患者中,发病后≤6 h进行介入治疗为影响患者治疗后血清FGF21水平、近期疗效与随访不良心血管事件的重要因素（P<0.05）。结论：发病后≤6 h介入治疗急性ST段抬高型心肌梗死可促进血清FGF21的释放,提高治疗近期疗效,改善心功能,也可降低远期不良心血管事件的发生,介入手术时间窗与血清FGF21的表达存在相关性。     

血清ANGPTL4联合Nesfatin-1对急性ST段抬高型心肌梗死患者PCI术后无复流的预测价值研究

摘要 目的：探讨血清血管生成素样蛋白 4（ANGPTL4）联合摄食抑制因子1（Nesfatin-1）对急性ST段抬高型心肌梗死（ASTEMI）患者经皮冠状动脉介入（PCI）术后无复流的预测价值。方法：选择2017年2月至2020年10月我院收治的339例ASTEMI患者,根据术后心肌梗死溶栓治疗（TIMI）分级将患者分为无复流组（TIMI血流0～2级,61例）和正常血流组（TIMI血流3级,278例）。比较两组患者基线资料、血清ANGPTL4和Nesfatin-1水平、实验室指标。多因素Logistic回归分析ASTEMI患者PCI术后发生无复流的影响因素,受试者工作特征（ROC）曲线分析血清ANGPTL4、Nesfatin-1预测ASTEMI患者PCI术后发生无复流的效能。结果：无复流组年龄、PCI术前心率、左室重量指数（LVMI）、休克指数、冠脉痉挛、血糖、冠脉病变长度、冠脉病变支数、白细胞计数、中性粒细胞计数、肌酸激酶同工酶（CK-MB）、心肌肌钙蛋白I（cTnI）高于正常血流组（P＜0.05）,收缩压、左心室射血分数（LVEF）、血清ANGPTL4和Nesfatin-1水平低于正常血流组（P＜0.05）。低水平Nesfatin-1、低水平ANGPTL4、高休克指数、冠脉痉挛是ASTEMI患者PCI术后发生无复流的危险因素（P＜0.05）。联合ANGPTL4、Nesfatin-1预测ASTEMI患者PCI术后发生无复流的曲线下面积（AUC）为0.885,高于ANGPTL4、Nesfatin-1单独预测的0.751、0.725。结论：PCI术后无复流ASTEMI患者血清ANGPTL4、Nesfatin-1水平降低,且血清Nesfatin-1、ANGPTL4水平降低与ASTEMI患者PCI术后无复流的发生密切相关,对ASTEMI患者PCI术后无复流具有一定的预测价值。
