脉压与冠状动脉病变严重程度的相关研究

近年来大量研究均提示脉压是冠心病新的危险因子，其对冠心病发生和死亡的预测作用甚至大于收缩压与舒张压。我们对257例接受冠状动脉(冠脉)造影病人的脉压及冠脉病变特点进行了综合分析，旨在探讨脉压水平与冠脉病变严重程度的相关关系。     

368例冠心病冠脉病变特点与中医证型的相关性研究

老年冠心病患者脉压与冠脉病变程度的相关关系

目的探讨老年冠心病患者脉压(PP)水平与冠脉病变严重程度的相关关系。方法对257例入选患者行选择性冠脉造影术,并采用Gensini冠脉评分系统对病变严重程度进行定量记分,测量外周肱动脉血压并记录冠心病危险因素,统计分析PP与冠状动脉病变严重程度的相关性。结果冠心病患者中,随病变支数的增加、病变范围的增大以及冠脉狭窄程度危险分级的增高,PP逐渐增高,其中左主干病变者PP最高。校正其他混杂因素后PP每增加10mmHg,对数转换的Gensini积分平均可增加0.128(P=0.007)。SBP在总体冠心病患者中显著高于正常者,但各亚组与正常者差异不大,仅三支病变组显著高于正常组与单支病变组。各组平均动脉压未见有统计学意义,DBP则有逐渐减小的趋势。结论在冠心病人群中,PP与老年冠心病患者(≥60岁)冠脉病变严重程度独立相关,且相关性优于SBP及DBP。

目的探讨有创主动脉脉压（PP）水平与冠状动脉病变程度的关系。方法行冠状动脉造影术患者194（男103,女91）例;年龄（64±11）岁,造影同时测量主动脉血压。冠状动脉病变严重程度用冠状动脉病变支数及冠脉病变积分来表示。结果冠状动脉病变影响因素较多,如年龄、高血压史、糖尿病史、高血脂史等,其中冠脉狭窄组主动脉收缩压（SBP）、PP、脉压指数（PPI）显著高于非冠脉狭窄组,差异具统计学意义。其增高水平与冠脉狭窄程度呈线性关系。多因素回归分析显示:PP、年龄与冠脉狭窄程度密切相关。结论主动脉PP与冠脉病变严重程度相关,且可能是冠脉病变的独立危险因素。     

Coronary Sarcoidosis Presenting as Acute Coronary Syndrome

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.

Coronary Atherosclerotic Precursors of Acute Coronary Syndromes

Background

The association of atherosclerotic features with first acute coronary syndromes (ACS) has not accounted for plaque burden.

Coronary Thromboembolism with Fatal Outcome Following Coronary Angiography

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.     

Spontaneous Multivessel Coronary Spasm During Diagnostic Coronary Angiography

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.     

Percutaneous Transluminal Coronary Angioplasty of Single Coronary Artery

The presence of single coronary artery is a very rare finding on coronary arteriography. This type of coronary artery anomaly was revealed in a 54-year-old patient with exertional angina refractory to full medical treatment and positive exercise test. The unique coronary vessel presented significant stenosis in the distal segment of circumflex artery—which continued as right coronary artery—and was successfully dilated with conventional balloon angioplasty.     

Coronary collaterals

A 79-year-old man with onset of typical angina pectoris wasreferred to our institution for suspected coronary artery disease.We performed non-invasive coronary angiography using
