Congestive heart failure is a major and growing public health problem. Its prevalence is 3-20 per 1,000, and increases steeply with age. Coronary heart disease is the underlying cause in 50% of the cases, idiopathic cardiomyopathy in 20%. Survival at 5 years after the onset of heart failure in the Framingham study was 25% in men and 38% in women; the mortality rate of heart failure patients was 6-7 times that of the general population. Three variables--functional class, natremia, left ventricular ejection fraction--are powerful prognostic factors. Quality of life of heart failure patients is severely impaired.
充血性心力衰竭是一个日益严重的重大公共卫生问题。其患病率为千分之三至二十，并随年龄急剧上升。冠心病是50%病例的潜在病因，特发性心肌病占20%。在弗雷明汉姆研究中，心力衰竭发作后5年男性的生存率为25%，女性为38%；心力衰竭患者的死亡率是普通人群的6至7倍。三个变量——功能分级、血钠浓度、左心室射血分数——是强有力的预后因素。心力衰竭患者的生活质量严重受损。
