| Abstract: | A WHO standard questionnaire for the detection of angina pectoris was used in examination of 6914 males aged 40 to 59. The character of the pain syndrome was correlated with risk factor (RF) levels, the prevalence of ECG-signs of ischemic changes, the incidence of cases of myocardial infarction (MI) during a 5-year follow-up period. Examinees with angina pectoris had the highest levels of systolic and diastolic AP, cholesterol, body mass, the highest frequency of lethal and nonlethal MI. Examinees with chest pains resulting from physical exercise but atypical of angina had higher levels of the main RF and ECG-signs of ischemic changes and higher rates (2-fold) of new cases of MI and its mortality as compared to persons without chest pains or with pains unrelated with physical exercise during a 5-year prospective study. This evidence suggests a necessity of a more detailed investigation of the latter group to reach the entire group of CHD patients. |
