Left ventricular function during haemofiltration and haemodialysis: a comparative study.
The relationship between systemic haemodynamics and left ventricular performance during HF and HD was evaluated by M-mode echocardiography. In patients with normal cardiac function and similar rates of fluid removal, special attention was paid to the effects of solute transport and buffer. Convective transport, independent of the replacement buffer, produces an increase in systemic vascular resistance with no changes in ventricular function. In contrast, a diffusive transport induces different effects depending on the dialysate buffer: acetate decreases vascular resistance and bicarbonate significantly improves myocardial contractility shifting the cardiac function curve to the left.
