Is Heart Rate Recovery Really Associated with Severity of Coronary Artery Disease in Patients with Normal Exercise Treadmill Test?

Abstract

Background and Objectives: Rapid diagnosis and treatment of cardiovascular diseases is really helpful in reducing further complications. There are different modalities for this goal but each has benefits and limitations. Exercise Treadmill Test (ETT) is a non-invasive, cheap and accessible test. Coronary CT Angiography (CTA) is recently considered as an applied modality for assessing severity of Coronary Artery Disease (CAD). In this study we aimed to investigate possible association between Heart Rate Recovery (HRR) in ETT and severity of CAD in CTA.
