Resumo

Primary microvascular angina (PMA) is a common clinical condition associated to negative impact on quality of life (QOL) and reduced physical capacity. This study aimed at evaluating the effects of aerobic physical training (APT) on myocardial perfusion, physical capacity, and QOL in patients with PMA. We investigated 12 patients (53.8 +/- A 9.7 years old; 7 women) with PMA, characterized by angina, angiographycally normal coronary arteries, and reversible perfusion defects (RPDs) detected on Tc-99m-sestamibi-SPECT myocardial perfusion scintigraphy (MPS). At baseline and after 4 month of APT, the patients underwent MPS, cardiopulmonary test, and QOL questionnaire. Stress-rest MPS images were visually analyzed by attributing semi-quantitative scores (0 = normal; 4 = absent uptake), using a 17-segment left ventricular model. Summed stress, rest, and difference scores (SDS) were calculated. In comparison to the baseline, in the post-training we observed a significant increase in peak-VO2 (19.4 +/- A 4.8 and 22.1 +/- A 6.2 mL center dot kg(-1)center dot minute(-1), respectively, P = .01), reduction of SDS (10.1 +/- A 8.8 and 2.8 +/- A 4.9, P = .008), and improvement in QOL scores. Physical training in patients with PMA is associated with reduction of myocardial perfusion abnormalities, increasing of physical capacity, and improvement in QOL. The findings of this hypothesis-generating study suggest that APT can be a valid therapeutic option for patients with PMA. (AU)
