Objective. To assess the haemodynamic effects of short-term treatment with dofetilide in comparison with sotalol in patients with ischaemic heart disease. Methods. Twelve patients with ischaemic heart disease and sustained ventricular tachycardia were treated with dofetilide [500 æg twice daily (b.i.d.)] or sotalol (160 mg b.i.d., randomised sequence separated by wash-out period) for 3-5 days. Right-heart catheterisation was performed at baseline and at the end of each short-term treatment phase. Results. The main findings were a significant reduction in heart rate, mean systemic pressure and cardiac index (-13%) during treatment with sotalol. Conversely, cardiac index increased significantly during dofetilide (mean percentage change 11%) with no effect on heart rate and systemic blood pressure. Conclusions. Oral dofetilide exerts favourable haemodynamic effects in comparison with D,L -sotalol following short-term oral treatment. In view of these observations, the use of dofetilide may be proposed also in patients with ventricular tachyarrhythmias associated with impaired left-ventricular function. Whether the haemodynamic differences between dofetilide and D,L -sotalol are the basis for differences in tolerability remains to be evaluated.
