CLINICAL FEATURES OF MANIFESTATIONS OF MYOCARDIAL ISCHEMIA IN PATIENTS WITH STABLE ANGINA AND CHRONIC OBSTRUCTIVE PULMONARY DISEASE

Abstract

Aim.To evaluate the comparative frequency of various manifestations of myocardial ischemia depending on chronic obstructive pulmonary disease (COPD), its severity and pulmonary hyperinflation (PHI) in patients with stable effort angina having indications for planned endovascular myocardial revascularization. Materials and methods. Systematically selected 605 patients with stable effort angina with a history of long-term smoking, among which spirography identified 142 patients with COPD, were checked for the incidence of various manifestations of myocardial ischemia, as estimated by the classification of Diamond A.G. (1983). Results.Atypical angina occurred in patients with COPD 1.6 times more often (p=0.021), and dyspnea without other manifestations of myocardial ischemia – 1.8 times more often (p=0.025) than in the control group. There was an increase in the incidence of atypical angina and dyspnea in COPD patients from grade III, and also in case of PHI. Conclusion.COPD leads to a change in the manifestations of myocardial ischemia in patients with stable angina, which is accompanied by an increase in the incidence of atypical angina and dyspnea in patients with severe COPD and in case of PHI.
