Epidemiology of heart failure

摘要: Analysis of 34 years follow-up Framingham Study data provides clinically relevant insights into the prevalence, incidence, secular trends, prognosis, and modifiable risk factors for occurrence heart failure in a general population sample. Heart was found to be highly prevalent, affecting about 1% persons their 50s rising progressively with age afflict 10% 80s. The annual incidence also increased age, from 0.2% 45 54 years, 4.0% men 85 94 approximately doubling each decade age. Women lagged slightly behind at all ages. Male predominance because higher rate coronary disease, which confers fourfold failure. failure, once manifest, lethal, 37% 33% women dying within 2 diagnosis. 6-year mortality 82% 67% women, corresponded death eightfold greater than that same Sudden common mode exitus accounted 28% cardiovascular deaths 14% Hypertension disease were predominant causes more 80% clinical events. Factors reflecting deteriorating cardiac function associated substantial increase overt These include low vital capacity, sinus tachycardia, ECG evidence left ventricular hypertrophy.(ABSTRACT TRUNCATED AT 250 WORDS)
