              Abstract

              Continued assessment of temporal trends in mortality and epidemiology of specific cardiovascular diseases in South America is needed to provide a scientific basis for rational allocation of the limited health care resources, and strategies to reduce risk and predict the future burden of cardiovascular disease. We reviewed the epidemiology of cardiomyopathies, adult valve disease, and heart failure (HF) in South America. Diseases of the circulatory system are the main cause of death based on available data from approximately 50% of the South American population. Among the cardiovascular causes of death cerebrovascular disease is predominant followed by ischemic heart disease, other heart diseases, and hypertensive disease. Of note, cerebrovascular is the main cause of death in females and race also influenced cardiovascular mortality rates. HF is the most important cardiovascular reason for hospitalization due to cardiovascular disease of ischemic, idiopathic dilated cardiomyopathy, valvular, hypertensive and chagasic etiologies. Also, HF presents high mortality especially of Chagas' disease. HF and etiologies associated with HF are responsible for 6.3% of causes of deaths. Rheumatic fever is the leading cause of valvular heart disease. The findings have important public health implications because the allocation of health care resources, and strategies to reduce risk of HF should also consider the control of Chagas' disease and rheumatic fever in South American countries.
