[Multiple cause of death in cardio- and cerebrovascular diseases].

In order to validate mortality studies, we described the role of hypertension at the time of death of people who died during April and May 1985. This analysis take into account all the causes listed in death certificates and not only the underlying cause. A proportional mortality design was used to evaluate the relationship of hypertension, cerebrovascular and cardiovascular disease. The number of deaths associated to hypertension was larger by multiple cause than by underlying cause. The odds ratio for hypertension and ischemic heart disease was 4.1 adjusted by age and sex, and 21.1 for cerebrovascular disease.
