Effect of myocardial revascularisation on left ventricular systolic function in patients with and without viable myocardium: should non-viable segments be revascularised?
To assess the effect of surgical revascularisation on left ventricular (LV) systolic function in patients with viable and non-viable dysfunctional LV segments determined by low dose dobutamine stress echocardiography (DSE). ⋯ It appears that patients with LV dysfunction, but without viable myocardium, may also benefit from myocardial revascularisation. Functional recovery continuously occurs throughout the first year after surgical treatment.
