作者以61例患有中度和重度慢性二尖瓣反流疾病患者为对象,对其心血管功能与年龄之间的关系进行了研究。其中20例系冠心病患者,占33％(他们均有1枝或多枝冠状动脉管腔狭窄在50％以上)。 61例病人中,年龄在60岁以下者33例,其系统动脉压、肺动脉压、左室舒张期末压和肺毛细血管嵌顿压,均较年龄在60或60岁以上的28例患者为低(P<0.05)。在41例未并发冠心病的患者中,年龄在60或60岁以上者14例,他们的系统动脉压、左室舒张期末压,都高于年龄在60岁以下的27例病人(P<0.05)。因此作者认为,左室舒张期末压的高低,既与患者年龄大小有关,又可提示病人是否患有冠心病,所以患有二尖瓣反流的老
The authors studied 61 patients with moderate and severe chronic mitral regurgitation disease, the relationship between cardiovascular function and age were studied. Among them, 20 cases were coronary heart disease, accounting for 33% (all had 1 or more branches of coronary artery stenosis in 50% or more). Among the 61 patients, 33 patients aged below 60 years old had lower systemic arterial pressure, pulmonary arterial pressure, left ventricular end-diastolic pressure, and pulmonary capillary incarceration pressure than those of 28 patients aged 60 or over (P <0.05). Of the 41 patients without coronary heart disease, 14 were aged 60 or older, and their arterial pressure and end-diastolic pressure were significantly higher than those of patients under 60 years of age (P <0.05) ). Therefore, the authors believe that the level of left ventricular end diastolic pressure, both with the age of patients, but also prompts patients with coronary heart disease, so suffering from mitral regurgitation
