Asymptomatic Left Ventricular Systolic Dysfunction is one clinical unknown situation for many physicians, but it has its clinical characteristics well stated, and also we know its potential evolution, prognosis and treatment.
Asymptomatic left ventricular dysfunction is documented in general population in around 2%. Patient with this disease could evaluate to symptomatic forms in about 35% in a period of 4 years. The multicenter studies had showed that patients with this disease could present mortality around 12% in 4 years. These data allow us to conclude that the well known malignity seem in patients with heart failure it’s not observed in these asymptomatic patients.
The treatment with ACE inhibitors and probably with beta-blockers enhance this good evolution, so all patients with asymptomatic left ventricular systolic dysfunction should be treated with these drugs. Since asymptomatic left ventricular dysfunction is more benign than the symptomatic one, pacemaker to treat heart failure, implantable defibrillators, and heart transplantation were not indicated in this phase of the disease.
