title: Impairment of left ventricular diastolic function during coronary artery bypass grafting.
abstract: Twelve patients were studied by transoesophageal Doppler echocardiography to determine diastolic function during coronary artery bypass grafting. Haemodynamic and Doppler-derived variables were measured after induction of anaesthesia and after closure of the sternum. Early diastolic filling of the left ventricle decreased from 55% to 35% during surgery. The contribution of atrial contraction to left ventricular filling increased from 41% to 62% (p less than 0.001). We conclude that coronary artery bypass grafting results in impairment of diastolic function during the operation.
