Higher prevalence and greater severity of coronary disease in short versus tall men referred for coronary arteriography.
The incidence of myocardial infarction is higher in short individuals than in tall ones. To test whether the prevalence and severity of coronary disease is greater in short than in tall individuals, we compared a group of short men (height < [mean height - one SD]) to a group of tall men (height > [mean height + one SD]) drawn from a sample of 1046 consecutive men referred for coronary arteriography. Short men had a higher frequency of > or = 50% diameter stenosis; more diseased vessels (1.61 +/- 1.09 vs 1.15 +/- 1.11, p = 0.0004); a higher frequency of three-vessel disease (26.8% vs 16.1%, p = 0.04); and more total occlusions (40.1% vs 27.3%, p = 0.03). By multivariate analysis, height independently predicted > or = 50% lesions in the right coronary artery (p = 0.01) and left anterior descending artery (p = 0.06); three-vessel disease (p = 0.04); total occlusion (p = 0.04); and the number of diseased vessels (p = 0.005). This higher prevalence and greater severity of coronary disease may explain the higher incidence of and deaths caused by myocardial infarction previously reported in short men.
