Pressão arterial central e braquial em pacientes idosos com diferentes graus de estenose coronariana: relação com o número de internações hospitalares

Abstract

The coronary atherosclerosis may reflect the state of major arterial vessels and may be associated with different central and peripheral blood arterial pressures. Systolic (SP) and pulse pressure (PP) of patients with different coronary lesion degrees were assessed during coronary angiography. Cardiovascular events (CV) and hospital admissions were monitored for 12 months. Participants were classified as: without coronary lesion (G-I, n = 54); with mild and moderate coronary lesion (G-II, n = 42); and severe coronary lesions (G-III, n = 95). Both pressures did not differ among the groups (p > 0.05). Central pressures exceeded brachial pressures in all groups (p < 0.05). The G-III status was associated with more hospital admissions than G-I and G-II (p < 0.05). The systolic pressure and pulse pressure were not significantly correlated with the number of admissions. In this older population, for different coronary lesion degrees we found similar central and brachial pressures. The main determinant of hospital admissions and Cardiovascular events was severity of coronary stenosis.
