【摘要】 目的:探讨急性心肌梗死(AMI)患者冠状动脉病变严重程度与脉压和脉压指数的关系。方法:对185例AMI患者进行冠状动脉造影术,冠状动脉病变严重程度用冠状动脉病变支数和Gensini积分来表示,并测定收缩压(SBP)和舒张压(DBP)并计算脉压(PP)及脉压指数(PPI)。结果:与脉压<65mmHg的患者相比,脉压(?)65mmHg的患者冠状动脉3支血管病变的患病率和Gensini积分显著增高(P<0.01)。与PPI<0.500的患者相比,PPI(?)0.500的患者冠状动脉3支血管病变的患病率和Gensini积分亦显著增高(P<0.01)。结论:PP和PPI与AMI患者冠状动脉病变程度密切相关,在临床上具有指导作用。更多还原

【Abstract】 Objective:To explore the relationship of pulse pressure and pulse pressure index to the severity of coronary artery le- sions in the acute myocardial infarction(AMI)patients.Methods:185 AMI patients were performed coronary angiography.The severity of coronary artery lesions was evaluated by the number of diseased arteries and the Gensini score.Brachial systolic blood pressure(SBP) and diastolic blood pressure(DBP)were measured,and pulse pressure(PP)and pulse pressure index(PPI)were calculated.Results: Compared with the patients with PP<65mmHg,the patients with PP(?)65mmHg had higher incidence of 3 coronary artery disease and higher Gensini score(P<0.01).Compared with the patients with PPI<0.500,the incidence of 3 coronary artery disease and Gensini score of the patients with PPI(?)0.500 also increased(P<0.01).Conclusion:PP and PPI are closely related to the severity of coronary artery le- sions in AMI patients.This result can be beneficial toclinical indication.更多还原
