The Predictive Role of Lead aVR in Patients Performed Exercise Treadmill Test For The Early Diagnosis of Erectile Dysfunction

Abstract

Objectives: Erectile dysfunction (ED) is defined as the inability to reach and/or maintain an erection to successfully perform sexual intercourse and is one of the most common sexual complaints by men of all ages. Several risk factors have been detected in the etiology of ED and atherosclerosis is found in vast majority of them. For this purpose, we aimed to investigate lead aVR in treadmill exercise test (TET) whether it is associated with ED. Methods: Total 150 patients with suspected coronary artery disease (CAD) who had undergone the TET according to Bruce protocol were included. We assessed the prevalence and severity for the ED. All tests and ST segments were analysed by two blinded cardiologists. Results: Patients were categorized ED group and non-ED group. The mean age was similar between two groups. ED group had more CAD, lower metabolic equivalent of task (MET) (8.8±1.8 vs. 12.6±2, p< 0.001), and lower double product (maximum heart rate x systolic blood pressure) (20634±4653 vs. 24368±3946, p< 0.001). ST elevation in lead aVR in the recovery phase first minute was higher the ED group (0.85±0.9 vs. 0.49±0.5, p=0.004). Conclusion: Premature CAD risk is increased in individuals with ED and ED is commonly seen in patients with CAD. This study gives us that TET provides more information beyond the classical indicators of ED.
