Clinical Trial Summary

The study aim is to compare the effects produced by two different exercise training modalities on atrial function evaluated by speckle-tracking echocardiography on hypertensive patients with coronary artery disease. 50 males patients will be randomized to interval training or combined training the latter including both aerobic and resistance exercises. The training period will last 12 weeks. The protocol will provide two different assessment of atrial function: -acute: after a single session of exercise; - 12 weeks: at the end of exercise training protocols.

Description:

This is a prospective randomized two- arms, single-blinded, parallel trial evaluating the effects of two different exercise training modalities on atrial function, assessed by speckle-tracking echocardiography, on hypertensive patients with coronary artery disease. First endpoint will be: between-groups comparison of exercise-induced changes on peak atrial longitudinal strain (PALS). Secondary endpoints will be: exercise-induced changes on diastolic function and left ventricular strain. We will include 50 patient with hypertension and underlying coronary artery disease, evaluated for entering a cardiac rehabilitation program. Patients that will be judged suitable for the study will be randomized, with a 1:1 ratio, to interval training (IT) or combined training (CT) the latter including both aerobic and resistance exercises. Each patient will undergo three visits. At visit 1 in which patients will perform a first echocardiography with evaluation of the acoustic window and an ergometric test (for excluding myocardial ischemia and for establishing the training intensity); visit 2- acute evaluation- :patients will undergo an echocardiographic assessment before and within 30 minutes after a single exercise session (alternatively interval or combined training according to the randomization code). Visit 3: at 12 weeks all patient will perform a final echocardiography evaluation and a second ergometric test. Patients of both groups will exercise three times/week for 12 weeks. Each exercise session will last 45 minutes
