A Randomized, Allocation-concealed, Assessor-blinded, Parallel-group Trial Evaluating the Association Between Erectile Dysfunction and Left Ventricular Diastolic Dysfunction and Comparing the Effects of Tadalafil, SGLT2 Inhibitors, and Their Combination in Patients With Metabolic Syndrome
Abstract
Metabolic syndrome is associated with an increased risk of cardiovascular disease and is commonly accompanied by erectile dysfunction and subclinical cardiac dysfunction. Erectile dysfunction and left ventricular diastolic dysfunction may share common underlying mechanisms, including endothelial dysfunction and microvascular impairment.
This study aims to investigate the association between erectile dysfunction and left ventricular diastolic dysfunction in men with metabolic syndrome, and to evaluate the effects of different treatment strategies, including tadalafil and SGLT2 inhibitors, on both erectile function and cardiac diastolic function.
Participants will be randomly assigned to receive tadalafil, an SGLT2 inhibitor, or a combination of both for a duration of three months. Clinical, echocardiographic, and functional assessments will be performed at baseline and after treatment.
The results of this study may improve understanding of the link between cardiovascular and sexual dysfunction and help guide therapeutic approaches in this patient population.
Conditions: Erectile Dysfunction, Left Ventricular Diastolic Dysfunction, Metabolic Syndrome.
Primary outcome: Change in erectile function assessed by the International Index of Erectile Function (IIEF).
Enrollment: 60 participants.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 60 participants or records.
