Peripheral Arterial Responses to Treadmill Exercise Among Healthy Subjects and Atherosclerotic Patients

Abstract

Half of our CAD patients manifested diminution in PWA that was consistent with peripheral arterial vasoconstriction during the early phases of treadmill exercise. Such paradoxical vasoconstrictive responses were not observed in normal subjects and, therefore, they may represent generalized vascular pathology secondary to atherosclerosis.

Exercício físico e disfunção endotelial

“…Rozanski et al 39 compared the peripheral blood flow response in 57 coronary patients and 50 apparently healthy individuals, submitted to physical exercise on an ergometric treadmill. The results showed that, among the healthy individuals, 76% showed vasodilation throughout the exercise, whereas 35% of the individuals with CAD showed progressive vasoconstriction.…”

Assessment of endothelial function in the patient with erectile dysfunction: an opportunity for the urologist

“…RH-PAT has been extensively correlated to early and clinically relevant CAD. [84][85][86][87][88][89] For instance, RH-PAT results were significantly impaired in patients with exercise-induced myocardial ischemia. 87 More importantly, it is similar to FMD in representing a true physiological reflection of peripheral endothelial function, [90][91][92] and is particularly useful in conditions such as diabetes [93][94][95] or the metabolic syndrome 96,97 that impair endothelial function.…”
