Aim: to study the severity of myocardial ischemia in pts with stable COPD and concomitant ischemic heart disease (IHD). Materials and Methods: We studied 101 pts divided into 3 groups: 1st – 44 (43,6%) males (age – 58,4±6,0 yrs) with COPD and stable angina, 2nd – 31 (30,7%) males (age – 55,4±4,4 yrs) with COPD, 3rd – 26 (25,7%) males (age – 58,8±8,6 yrs) with stable angina. Measurements included clinical status and 24-hour ambulatory Holter ECG monitoring. Results: Results in % (# of patients) are presented in the Table. Conclusion: coexistence of COPD and angina leads to the increase in quantity of symptomatic and silent episodes of ST-segment depressions, aggravating myocardial ischemia.
