Central aortic hemodynamics following acute lower and upper-body exercise in a cold environment among patients with coronary artery disease.

ABSTRACT: Exercise is beneficial to cardiovascular health, evidenced by reduced post-exercise central aortic blood pressure (BP) and wave reflection. We assessed if post-exercise central hemodynamics are modified due to an altered thermal state related to exercise in the cold in patients with coronary artery disease (CAD). CAD patients (n = 11) performed moderate-intensity lower-body exercise (walking at 65-70% of HR_max) and rested in neutral (+ 22 °C) and cold (- 15 °C) conditions. In another protocol, CAD patients (n = 15) performed static (five 1.5 min work cycles, 10-30% of maximal voluntary contraction) and dynamic (three 5 min workloads, 56-80% of HR_max) upper-body exercise at the same temperatures. Both datasets consisted of four 30-min exposures administered in random o
