Cardiac failure with propranolol.

Failure of ranitidine to interact with propranolol.

Failure of ranitidine to interact with propranolol The histamine H2-receptor antagonist ranitidine has recently been introduced into clinical practice for the treatment of peptic ulcer. Its therapeutic effects appear similar to those of cimetidine, but early reports suggest that it does not affect hepatic drug metabolism.' 2 This probably reflects a change in chemical structure, in that the cen...

Huge Intracavitary Cardiac Hyadatid Cyst Presenting with Heart Failure

Although cardiac involvement is an infrequent presentation in human hydatidosis, early diagnosis and prompt surgical intervention of cardiac hydatid cyst are of utmost importance for the prevention of potential complications. We report a young female patient who presented with a huge cardiac hydatid cyst and severe heart failure symptoms undergoing successful surgical cyst removal with late fol...

Replacement of carvedilol for propranolol in patients with heart failure.

BACKGROUND Large clinical trials using the betablockers carvedilol, metoprolol, bisoprolol and nebivolol have demonstrated improvement of survival and symptoms in patients with heart failure. Despite the lack of scientific evidence, it is plausible that their beneficial effects are extensible to other betablockers. OBJECTIVE To evaluate the impact of the replacement of carvedilol for proprano...

The effects of propranolol on cardiac conduction.

was used as a measure of A-V conduction and the interval from the His bundle electrogram to the S wave (H-S interval) was used as a measure of intraventricular conduction. Propranolol significantly prolonged the P-H interval in every patient at all paced heart rates, and it had no effect on the H-S interval. In two patients propranolol prolonged the effective refractory period of the atrioventr...
