Computer classification of screening study of risk factor for ischemic heart disease in 20-60 year old subjects

Screening was performed of 2162 industrial workers aged 20-60 years for risk factors for ischemic heart disease. The computer classification of all subjects investigated gave the following distribution: healthy subjects without any risk factors-21 men (1.59%), 26 women (2.61%); healthy subjects with risk factors-609 men (46.14%) and 469 women (47.09%); subjects with borderline arterial hypertension without other risk factors-13 men (0.98%) and 10 women (1.0%); subjects with arterial hypertension concomitant with other risk factors-295 (22.35%) and 224 women (22.49%). There were no subjects with ischemic heart disease without the major and secondary risk factors. The subjects with both risk factors and ischemic heart disease were 154 men (10.01%) and 216 women (18.0%). ECG changes (by Minnesota code) were found in 339 male (25.0%) and 178 female subjects (14.8%).
