The function of left ventricular basal segments is most important for long-term recovery

The strongest association for prediction of LV recovery after metoprolol treatment was found regarding function of basal segments of the ventricle. Patients that responded favourably to beta-blockade had a significantly better CR, and treatment effect, in these segments. This gives further evidence for the importance of myocardial function in basal segments to the contribution of recovery and LV global function.
