Cardiovascular causes of death at Tshepong Hospital in 1 year, 1989-1990. A necropsy study.
Cardiovascular disease is the third most common cause of death in Tshepong Hospital in the western Transvaal, and the most common cause of death in patients older than 35 years. A prospective study was undertaken which included limited necropsies in 90 of the 167 cardiovascular disease deaths over 1 year. A reliable mortality pattern for cardiovascular deaths is described. Additionally, attention is paid to co-existing conditions. Conditions relating to cardiovascular disease, such as hypertension, benign hypertensive nephrosclerosis, atherosclerosis and obesity, were also evaluated. Cerebrovascular conditions were found in 32% of cardiovascular deaths. Intracerebral haemorrhage was found in 50% and cerebral infarction in 29% of cases. Fifty-seven per cent of cardiovascular deaths were due to cardiac conditions, the most common being pulmonary hypertension (31%), dilated cardiomyopathy and chronic rheumatic valvular disease (17% each) and hypertensive heart disease (14%). Forty-nine per cent of subjects were hypertensive, while 40% exhibited benign nephrosclerosis and only 3% of the examined vessels had signs of severe atherosclerosis. Tuberculosis was present in 13% of cases. The clinical diagnosis was the same as the final necropsy diagnosis in 38% of cases. These results emphasise the importance of performing necropsies to obtain reliable mortality statistics.
