Key result
Aerobic training improves LVEF in systolic dysfunction, reducing progressive cardiac enlargement post-MI.
Why the study?
Does aerobic physical training improve left ventricular remodeling in patients after myocardial infarction?
Does aerobic physical training improve left ventricular remodeling in patients after myocardial infarction?
Aerobic physical training is highlighted as an effective non-pharmacological strategy to improve LVEF and prevent adverse cardiac remodeling post-MI.
Supports aerobic training post-MI to improve LVEF; leaves open prospective RCTs on remodeling.
Post-myocardial infarction left ventricular remodelling should be considered an important therapeutic target in patients after an acute myocardial infarction, considering the heavy prognostic implication. The therapies used in these patients should reduce the progression of the left ventricular dysfunction to refractory heart failure. In order to prevent post-myocardial infarction cardiac remodelling, different therapies have been tested, and for ACE-inhibitors and beta-blockers a clear demonstration of efficacy has been obtained. Losartan and valsartan, two widely used angiotensin receptor blockers, demonstrated to be safe and equally useful compared to ACEI. The addition of spironolactone to the standard therapy for heart failure has a clear beneficial effect but the clinical use has been refrained by the risk of iperkaliemia. Aerobic physical training improves the left ventricular ejection fraction in patients with systolic dysfunction, reducing the progressive enlargement after myocardial infarction. The positive effect of aerobic training on cardiac remodelling might be related to the positive effect on neurhormonal assessment, to he improvement of microcirculatory myocardial perfusion and of endothelial function.
