Heart failure can be defined as the result of the alteration of different structures at the heart level (heart muscle layers and/ or great vessels) but it is mostly due to an alteration in the function of the left ventricular myocardium compromising the preload and post-load in the ventricles.In these patients there are clinical manifestations, such as: decrease in aerobic capacity, presence of choking sensation and tiredness and sometimes water retention, which can end up in peripheral edema and pulmonary congestion, evidencing an alteration in the functional capacity in their daily activities.
