Introduction: a considerable number of patients undergoing coronary arteriography do not present any atherosclerotic lesions in their coronary tree. The subgroup with chest pain and a positive ergometric test was included in the diagnosis of microvascular angina. Objective: determine the prevalence of microvascular angina in patients undergoing coronary arteriography. Methods: descriptive cross-sectional study of patients examined at the Hemodynamic Laboratory of the Center for Medical Surgical Research from 2010 to 2011, initially diagnosed with effort angina and with a positive ergometric test. The study universe was 1 452 patients undergoing coronary arteriography in the period. The sample consisted of the 452 patients who did not show any coronary atherosclerotic lesions. Results: 31.1 % of the patients undergoing coronary arteriography had microvascular angina, with a predominance of the female sex. Arterial hypertension was the main risk factor throughout the two years' evaluation. Conclusions: microvascular angina, a common condition in Cuba, is related to the presence of cardiovascular risk factors.
