Anterior and inferior myocardial infarction. Comparison with regard to some diseases and background factors.

A pilot study has shown a significant positive correlation between anterior myocardial infarction and arterial hypertension, serum cholesterol values above 300 mg/Ioo ml, chronic lung diseases, diabetes mellitus, and the number of sibs who had suffered from myocardial infarction.The tendency for infarction to recur in the same site was significant at a 5 per cent level.This work has its origin in the idea that patients suffering from anterior and inferior myocardial infarction may differ in certain respects.In arterial hypertension greater demands are made upon the left ventricle: patients with anterior infarction may, therefore, as a group have more hypertension than patients with inferior infarction.Differences be- tween the two types of infarction patients may be detectable in family history as well as in associated diseases and in previous environmental exposures.A similar comparison has not been found in the available literature.
