Angina pectoris, which is chronic coronary diseases, have the atherosclerotic background and negatively affecting the quality of life of the patient, develops as a result of narrowing of coronary vessels and /or disruption of oxygen supply-need balance. This study was aimed to investigate the relationship between exertional dyspnea, pulmonary function, functional capacity, and quality of life, with angina pectoris which affects mortality and causes the economic burden. Thirty-five patients with angina pectoris (57.80±8.06 years, Canada Class 2,3) were included in the study. Demographic data and posture, comorbidity, smoking status, factors that increase dyspnea, angina levels were recorded. Functional capacity with a six-minute walk test(6MWT), respiratory functions with spirometry, quality of life with Short Form-36 were assessed. Dyspnea at activity/rest were recorded and with Modified Borg scale (MBS), Modified Medical Research Council (MMRC) was evaluated. Ejection fraction (LVEF) was 60.14±7.60%, cigarette exposure was 31.50 (0-135) packxyears and dyspnea perceived by activity was 4.02±2.08. Climbing (65.7%) was the activity that was most increase dyspnea. FEV1 was 86.55±15.97, FEV1/FVC was 88.58±11.07, 6MWT % was 72.54±7, perceived exertional dyspnea at the end of the test was 0(0-2.75). Exertional dyspnea was moderately positively correlated with FEV1(L) (r:0.397, p:0.02), FVC(L) (r:0.387, p:0.02), moderate negatively correlated with quality of life parameters: physical role limitations (r:-0.457, p:0.01), physical functionality (r:-0.473, p˂0.01) but was not correlated with functional capacity (p˃0.05). Functional capacity was moderately positive correlated with PEF(L) (r:0.489, p˂0.01), FEF25-75% (r:0.366, p:0.03), and parameters of quality of life: physical functionality (r:0.409,p:0.02), energy/fatigue (r:0.395, p:0.02), general health (r:0.377 p:0.03). Dyspnea, quality of life, functional capacity, and pulmonary functions were correlated to each other in angina pectoris. The relationship between these parameters should not be neglected in the evaluation of the risk factors, patient clinic, and the effectiveness of the prescribed and/or administered treatments.
