[Atherosclerosis risk factors in patients examined by coronarography. IV. Relation of atherosclerosis risk factors and clinical manifestations of ischemic heart disease (myocardial infarct, angina pectoris)].

The total of 376 male and 63 female subjects is concerned. As an abnormal coronarogram, such a finding is estimated where at least one of coronaries showed more than 50% lumen obstruction. The occurrence rates of atherosclerotic risk-factors, angina pectoris and myocardial infarction have been studied with regard to the abnormal coronarograms. A special concern in male group is almost simultaneous occurrence of angina pectoris along with positive coronarogram. The occurrence of both studied factors shows an increase with more age. The percentage of IM occurrence is practically the same in all age groups studied regardless to the value of coronarographic score. However, the male subjects with both clear and suspected IM (especially in the age group up to 40 years) are stated to show higher occurrence of normal coronarographic findings (32 %). This is in agreement with the suggestion that also other factors are involved than the atherosclerotic affection of coronary bed, what demonstrates the complexness of pathophysiological mechanisms of IM genesis.
