近年来,随着人们生活水平的提高及生活方式的改变,患冠心病的人越来越多,且发病年龄呈下降趋势,冠心病已成为心脑血管疾病中的高发病。目前冠心病的治疗方式主要有内科介入治疗(PCI)、外科冠状动脉血管移植手术(CABG,即冠脉搭桥手术)以及内科药物治疗。而冠状动脉内支架置入术已成为冠心病介入治疗最主要的手段和方式,约80%的接受介入治疗的患者置入了支架。支架置入术开始用于临床时主要用在做冠状动脉球囊扩张时并发血管夹层、急性闭塞或濒临闭塞等情况,紧急置入支架以保持血流畅通,避免急诊外科手术及急性心肌梗死的发生。 相似文献

Sarcoidosis is a systemic disorder of uncertain etiology characterized by noncaseating granulomatous inflammation. The disease often involves the heart on autopsy, but the antemortem diagnosis of cardiac sarcoidosis is frequently missed. Cardiac involvement usually includes granulomatous inflammation or fibrosis of the myocardium, conduction system, or pericardium. We now describe a case of epicardial coronary involvement by sarcoidosis, where the diagnosis was made by surgical biopsy of the coronary artery in an African American man presenting with acute coronary syndrome and recurrent symptomatic restenosis following coronary intervention. The case extends the spectrum of common cardiac syndromes that cardiac sarcoidosis can masquerade as and highlights the importance of maintaining a high index of suspicion for early recognition and instituting specific treatment that might improve prognosis. A review of the literature also suggests the need for improvement in diagnostic approaches and prospective clinical trials to establish the best management strategy for this disease.

Background
The association of atherosclerotic features with first acute coronary syndromes (ACS) has not accounted for plaque burden.Objectives
The purpose of this study was to identify atherosclerotic features associated with precursors of ACS.Methods
We performed a nested case-control study within a cohort of 25,251 patients undergoing coronary computed tomographic angiography (CTA) with follow-up over 3.4 ± 2.1 years. Patients with ACS and nonevent patients with no prior coronary artery disease (CAD) were propensity matched 1:1 for risk factors and coronary CTA–evaluated obstructive (≥50%) CAD. Separate core laboratories performed blinded adjudication of ACS and culprit lesions and quantification of baseline coronary CTA for percent diameter stenosis (%DS), percent cross-sectional plaque burden (PB), plaque volumes (PVs) by composition (calcified, fibrous, fibrofatty, and necrotic core), and presence of high-risk plaques (HRPs).Results
We identified 234 ACS and control pairs (age 62 years, 63% male). More than 65% of patients with ACS had nonobstructive CAD at baseline, and 52% had HRP. The %DS, cross-sectional PB, fibrofatty and necrotic core volume, and HRP increased the adjusted hazard ratio (HR) of ACS (1.010 per %DS, 95% confidence interval [CI]: 1.005 to 1.015; 1.008 per percent cross-sectional PB, 95% CI: 1.003 to 1.013; 1.002 per mm3 fibrofatty plaque, 95% CI: 1.000 to 1.003; 1.593 per mm3 necrotic core, 95% CI: 1.219 to 2.082; all p < 0.05). Of the 129 culprit lesion precursors identified by coronary CTA, three-fourths exhibited <50% stenosis and 31.0% exhibited HRP.Conclusions
Although ACS increases with %DS, most precursors of ACS cases and culprit lesions are nonobstructive. Plaque evaluation, including HRP, PB, and plaque composition, identifies high-risk patients above and beyond stenosis severity and aggregate plaque burden. 相似文献14.

ABSTRACT A case of fatal thromboembolic occlusion of the left coronary artery at selective coronary arteriography is described. The course of events and the findings at autopsy suggest that thrombotic material was deposited on one intravascular catheter and transferred to a second catheter inserted over the same guide wire. Contrast injection through the second catheter into the left coronary ostium resulted in immediate and fatal occlusion of the two major branches of the left coronary artery. 相似文献

Acute vasospastic angina, formerly known as Prinzmetal angina, is characterized by transient electrocardiographic changes that are not related to exertion. Its atypical presentation makes it difficult to establish the diagnosis, so it is probably underrecognized and therefore mismanaged. We treated a 49-year-old woman who presented with a 2-day history of chest pain associated with palpitations. Abnormal radionuclide stress test results prompted diagnostic coronary angiography, during which the patient reported chest pain and became hemodynamically unstable. Active coronary vasospasm at multiple sites was treated with intracoronary nitroglycerin and nicardipine, leading to immediate recovery.Our case highlights the importance of accurate, timely diagnosis of vasospastic angina, and of early recognition and management of spontaneous coronary spasm during angiography. 相似文献

Coronary microembolization 总被引:12,自引:0,他引:12
Atherosclerotic plaque rupture is a key event in the pathogenesis of acute coronary syndromes and during coronary interventions. Atherosclerotic plaque rupture does not always result in complete thrombotic occlusion of the entire epicardial coronary artery with subsequent acute myocardial infarction, but may in milder forms result in the embolization of atherosclerotic and thrombotic debris into the coronary microcirculation. This review summarizes the available morphological evidence for coronary microembolization in patients who died from coronary artery disease, most notably from sudden death. Then the experimental pathophysiology of coronary microembolization in animal models of acute coronary syndromes is detailed. Finally, the review presents the available clinical evidence for coronary microembolization in patients, highlights its key features--arrhythmias, contractile dysfunction, microinfarcts and reduced coronary reserve--, compares these features to those of the experimental model and addresses its prevention by mechanical protection devices and glycoprotein IIb/IIIa antagonism. 相似文献

Myocardial infarction (MI) size is the major determinant of the function of the left ventricle and thus of the prognosis of the patient. Attempts to limit infarct size therefore constitute an important goal in modern coronary care. There is evidence that intravenous thrombolytic therapy can lyse coronary artery thrombi, restore antegrade coronary blood flow, preserve myocardial viability and function and improve survival. The time interval from onset of infarction, the extent of remaining ischemic myocardium and the rate at which myocardial necrosis is progressing are factors influencing the extent of myocardial salvage in reperfusion. 相似文献
