A sustained release formulation of isosorbide-5-mononitrate with a rapid onset of action.

The clinical efficacy of a combined immediate-release and sustained-release preparation of isosorbide-5-mononitrate for angina pectoris is observed within a few minutes of administration. The preparation reduces the number of silent and painful ischaemic episodes and increases work and exercise capacity. The pharmacokinetic profiles accord with the circadian variation in cardiovascular disease.

Ventricular fibrillation due to long QT syndrome probably caused by clindamycin.

Prolongation of QT time interval may be provoked by a limited number of drugs, especially macrolide antibiotics. We describe a case of QT time interval prolongation induced by clindamycin with subsequent repeated ventricular fibrillation and resuscitation; there is no previous report in the literature of QT time prolongation caused by lincosamides.

[Left ventricular papillary fibroelastomas without relation to a heart valve--a report of 2 cases].

Papillary fibroelastomas are rare benign tumors of the heart. We report about two cases in which these tumors do not--as characteristically--arise from a heart valve but originate from the free wall of the left ventricle. In the case of a 74-year-old woman with signs of a cerebral ischemia in the vascular system of the A.
