Overview

abstract

  • Clinical data, function and compliance of left ventricle as well as regional wall motion were analysed in 17 patients with preoperatively limited left-ventricular function and signs of myocardial ischaemia after complete revascularisation surgery. Recatheterisation after 5.2 months on average after surgery showed improvement by one NYHA class, an increase of mean left-ventricular enddiastolic pressure, which was interpreted as "improved status of ischaemia", a decrease of left-ventricular compliance by 30%, of enddiastolic volume by 14% and of endsystolic volume by 20% (P less than 0.05). Loss of function occurred in 3 out of 92 bypasses. Up to the time of reporting, 22.4 months postoperatively, all patients have survived in a relatively satisfactory clinical state. All parameters of left-ventricular function as well as regional wall motion showed a tendency for improvement after surgery in the majority of patients. However, pre- and postoperative mean values were not significantly different (P greater than 0.05). Thus, despite clearcut improvement of clinical state and "ischaemia index", improvement of left-ventricular function and regional wall motion are not consistently demonstrable. The reasons of this discrepancy cannot be ascertained by this investigation. The quality of the surgical intervention and the sensitivity of parameter assessment cannot be held responsible.
