Usefulness of myocardial viability or ischemia in predicting long-term survival for patients with severe left ventricular dysfunction undergoing revascularization.
In 107 patients with coronary disease and severe left ventricular dysfunction, we examined the prognostic power of viability identified by dobutamine stress echocardiography. At a mean follow-up of 27 months, patients with viable myocardium who underwent revascularization had a significant survival advantage over all other patients (2-year survival 83.5% vs 57.2%, p = 0.0037).
