Abstract Background: There is overwhelming evidence that comprehensive cardiac rehabilitation (CR) is associated with a reduction in both cardiac mortality (26–36%) and total mortality (13–26%). These benefits make Cardiac rehabilitation one of the most clinically and cost-effective therapeutic interventions in cardiovascular disease management The left atrium plays a major role in left ventricle performance, LA function is a surrogate marker of LV diastolic function and the left atrial mechanical dysfunction occurs in LV systolic and diastolic dysfunction, coronary artery disease, myocardial infarction, hypertension, aortic stenosis and cardiomyopathy. The Objectives: the aim is to evaluate the effect of cardiac rehabilitation on atrial function using speckle tracking method following successful coronary revascularization for patients with their first presentation of acute anterior ST elevation myocardial infarction (STEMI). Patients and Methods: This study is a case control study which included 50 patients, admitted to the Cardiology department at Ain Shams University Hospitals with first acute anterior ST segments elevation myocardial infarction (STEMI) from December 2014 till August 2016 who underwent successful primary PCI to LAD, divided into two equal groups, the first included the patients who had cardiac rehabilitation and the second one included those who didn’t experience cardiac rehabilitation to assess the effect of cardiac rehabilitation on both atrial function using Speckle tracking method. Results: baseline clinical characteristics were similar in both patient groups. The study revealed that there was highly significant improvement in both groups (rehabilitation group and non-rehabilitation group) as regard LVEF after the follow up period. Also, there was significant improvement of E/A ratio and the peak systolic strain of LA at apical 4 chamber in the rehabilitation group while there was no significant change in the non-rehabilitation group. Conclusion: Cardiac rehabilitation has a favorable effect on left atrial function in patients with acute myocardial infarction and this may be a part of the mortality benefit of cardiac rehabilitation |
