为了区别老年人心脏疾患与左室结构同正常生理老化,作者对年龄≥75岁有代表性人群中的健康老年人随机选样进行纵向研究,随访4年以上,旨在探讨增龄对左室结构与功能的影响。本研究选择年龄75岁组和81岁组的老年人进行随访。75岁组31名,其中男11名,女20名;81岁组36名,男19名,女17名。除外心肌梗塞、中风、心绞痛、糖尿病、肺气肿、痴呆及近5年患过恶性疾病的患者和服用心血管药物与心电图不正常者。4年后,由于死亡及其他原因,两个年龄组被随访者各17名。检查包括测量血压、心率、心电图、超声心动图、
In order to distinguish between elderly patients with heart disease and left ventricular structure with normal physiological aging, the authors of a representative population of ≥75 years of age, a representative population of healthy elderly randomized longitudinal study, followed up for 4 years, to explore the effect of aging on left ventricular Structure and function of the impact. The study selected the elderly 75-year-old group and 81-year-old elderly were followed up. 31 aged 75, including 11 males and 20 females; 36 aged 81, 19 males and 17 females. Excluding myocardial infarction, stroke, angina, diabetes, emphysema, dementia, and those with malignant disease in the recent 5 years and those taking cardiovascular drugs and electrocardiogram abnormalities. Four years later, 17 of the two age groups were followed up for death and other reasons. Checks include measuring blood pressure, heart rate, electrocardiogram, echocardiography,
