左室功能障碍研究(SOLVD)始于1986年,目的是评价依那普利对大系列左室功能障碍患者的长期发病率及病死率的影响。SOLVD包括二个同时进行但又独立的试验。本文旨在了解(1)严重左室功能障碍和有充血性心力衰竭(CHF)症状的患者与无明显CHF史及未行CHF治疗患者的差别;(2)性别和种族对临床表现差异的影响。依据CHF的症状及需要治疗与否,将左室射血分数(LVEF)≤0.35的患者分为治疗和预防试验两组。预防组为不需用洋地黄、利尿剂和血管扩张剂治疗的患者。治疗组为有明显CHF并用上述药物治疗者。经筛选6797例患者进入本研究,占多中心检查
The Study of Left Ventricular Dysfunction (SOLVD) began in 1986 with the aim of evaluating the effect of enalapril on the long-term morbidity and mortality of patients with large series of left ventricular dysfunction. SOLVD includes two simultaneous but independent experiments. This article aims to understand (1) the differences between patients with severe left ventricular dysfunction and symptoms of congestive heart failure (CHF) and those without or without CHF; (2) the effect of gender and ethnicity on differences in clinical manifestations . According to the symptoms of CHF and the need of treatment, patients with left ventricular ejection fraction (LVEF) ≤0.35 were divided into two groups: treatment and prevention. The prevention group was treated without digitalis, diuretics and vasodilators. The treatment group was significantly CHF and treated with the above drugs. After screening 6797 patients entered the study, accounting for multi-center examination
