The results of bicycle ergometry and pharmacological tests with isoproterenol and dipyridamol, 24-hour monitoring and blood levels of endogeneous opioids were studied in 99 females with chest pain who had undergone angiography. Coronary microcirculation was examined in 29 patients by introducing albumin microspheres into the left ventricle. The angiography revealed coronary atherosclerosis in 30 patients, whereas its signs were not found in 8 females with documented coronary heart disease (CHD). The predictive value of positive exercise tests in females with angina pectoris was higher for the diagnosis of CHD, including its types without coronary atherosclerosis. In patients with cardialgias, the predictive values of exercise tests were equally low for the diagnosis of coronary atherosclerosis, vasospastic and microvascular CHD types. The patients with cardialgias caused by autonomic dyshormonal myocardiodystrophy showed low blood β-endorphin and leu-enkephalin levels.
