Insuficiencia mitral y remodelación ventricular: nuevas alternativas para su control
2016
The ventricular remodeling is a change in geometry and/or volume of the ventricular cavity non attributable to changes in the distension pressure, which produces a progressive increase in the time of the ventricular volume. Part of the mechanism responsible for it is the renal hypo perfusion, which produces an important loss in the glomerular filtration with the consequent activation of the system renina-angiotensin-aldosterone, which finally has an important contribution to the ventricular remodeling. At the present time, the use of s-blockers and inhibitors of the angiotensin converting enzyme of (IECA) constitutes a good alternative to avoid the process of remodeling n patients with cardiac insufficiency, caused by a damage in the cardiac muscle (miocarditis), ischemic muscular damage (acute coronary disease) or by valvular injury (endocardiosis). As a result of the degeneration to valvular myxomatous mitral (frequent in canine clinics), the patient develops cardiac insufficiency with left ventricular remodeling that in the long term ends up with the death of the animal. The use of s-blockers or IECAS or their combination can avoid greatly their remodeling and thus avoid ventricular dysfunction from appearing.
