[Race and left ventricle hypertrophy without hypertension and pulmonary heart disease].
OBJECTIVE
To analyze the association between black people and left ventricular hypertrophy (LVH) in the absence of hypertension and/or other cardiopulmonar disease.


METHODS
Data were collected from necropsies carried out in the Anatomopathologic Service (APS). Hospital Edgard Santos from 1970 to 1986, Salvador. It were included only subjects at ages > or = 20 years and free of hypertension and any cardiopulmonar disease. A LV wall > 1.6cm was considered as LVH (standardized criteria of the APS). Controls variables were age, sex, and absence of the mentioned diseases. It was used a case-control epidemiological study design and the association measured by "odds ratio" (OR) for no matched case-control study.


RESULTS
From the 208 subjects studied, 48 (23.1%) had LVH. There was no difference in the frequency of right ventricular hypertrophy between cases and controls (p > 0.05). The mean of heart weight was higher for LVH cases (p < 0.001), but there was no evidence of association between blacks and LVH (OR = 1.05, p > 0.05 and confidence interval at 95% = 0.8, 1.31. The highest odds possible for the association in this study (assuming that all 3 LVH losses were black subjects) would be 1.5, also no statistically significant.


CONCLUSIONS
In the absence of hypertension and other cardiopulmonar diseases, LHV is common in necropsies in Salvador, Brazil, with similar frequencies in blacks, whites and mullatos and seems not be a risk factor for hypertension in black people.
