摘要:
目的 探讨代谢综合征(MS)与急性心肌梗死(AMI)患者冠状动脉病变程度及预后的相关性。 方法 选取2019年1月—2020年12月期间新疆维吾尔自治区人民医院心内科救治的726例AMI患者作为研究对象,Gensini评分用以定量评估冠脉病变程度,终点事件定义为主要心血管不良事件(MACEs)的发生。采用多重线性回归分析研究MS及各组分与Gensini评分的相关性;采用多因素Cox回归分析研究MACEs发生的独立危险因素。 结果 MS组348例(47.9%),非MS组378例(52.1%)。与非MS组相比,MS组年龄更大,合并高血压、糖尿病、腹型肥胖、血脂异常比例更高,腰围、收缩压、空腹血糖、血尿素氮、低密度脂蛋白胆固醇、Gensini评分水平更高,血红蛋白水平较低,氯吡格雷服用比例更高,MACEs发生率更高,差异均有统计学意义(P < 0.05)。组分内比较发现:腹型肥胖组和空腹血糖升高组的Gensini评分显著升高,差异均有统计学意义(P < 0.05)。多重线性回归分析结果显示:空腹血糖升高和腹型肥胖与Gensini评分呈独立相关。多因素Cox回归分析结果显示:糖尿病和腹型肥胖是MACEs发生的独立危险因素。 结论 AMI患者合并MS十分常见,糖代谢异常和腹型肥胖与冠脉病变程度密切相关,并且明显影响患者预后。 Abstract:Objective To explore the correlation between metabolic syndrome (MS) with the degree of coronary artery stenosis and prognosis in patients with acute myocardial infarction (AMI). Methods There were 726 AMI patients as the subjects, from the Cardiology Department of Xinjiang Uygur Autonomous Region People's Hospital from January 2019 to December 2020. The Gensini score was used to quantitatively assess the degree of coronary artery stenosis and the clinical outcome was defined as major adverse cardiovascular events (MACEs). Multiple linear regression was used to analyze the correlation between MS and its components between Gensini score. Multivariate Cox regression was used to analyze the independent risk factors for MACEs. Results There were 348 patients (47.9%) in the MS group and 378 patients (52.1%) in the non-MS group. Compared with the non-MS group, patients in the MS group were older and had more combined hypertension, diabetes, abdominal obesity, dyslipidemia. Waist circumference, systolic blood pressure, fasting blood glucose, blood urea nitrogen, low density lipoprotein cholesterol and Gensini score were higher, hemoglobin levels were lower, clopidogrel utilization rate was higher and the incidence of MACEs was higher, the differences were statistically significant (P < 0.05). Internal comparison showed that Gensini scores were significantly increased in the group of abdominal obesity and elevated fasting blood glucose (P < 0.05). Multiple linear regression analysis results showed that elevated fasting blood glucose and abdominal obesity were independently correlated with Gensini score. Multivariate Cox regression analysis results showed that: diabetes and abdominal obesity were the independent risk factors for MACEs. Conclusion Patients with AMI complicated by MS were very common. Abnormal glucose metabolism and abdominal obesity were closely related to the degree of coronary artery stenosis, and significantly affect the prognosis of patients. -
