Reduced distribution and clearance of acetaminophen in patients with congestive heart failure.

Acetaminophen is a widely prescribed analgesic/antipyretic metabolized by hepatic glucuronide and sulfate conjugation. Twelve patients, 30-66 years of age, with stable Class III or IV congestive heart failure (CHF) and 12 healthy controls matched for age, sex, and weight received single 650-mg intravenous doses of acetaminophen. Pharmacokinetic variables were determined from multiple plasma acetaminophen concentrations measured by liquid chromatography during 12 h after the dose.

The treatment of angina pectoris with the new beta-receptor blocker carteolol. Results of a controlled trial in comparison with pindolol.

This trial comprised 40 patients with angina pectoris and reproducible ischaemic ST segment depression in the exercise ECG. Whenever possible the diagnosis of coronary heart disease was confirmed by coronary angiography. After a preliminary 7-day placebo period, 20 of these patients were treated for 4 weeks with 5-(3-tert-butylamino-2-hydroxy-propoxy)-3, 4-dihydro-2(1H)-quinolinone hydrochloride (carteolol hydrochloride, Endak, Endak mite), a nonselective beta-receptor blocker, having adrenergic properties (ISA) up to 30 times more powerful than those of propranolol.

[Coronary artery aneurysms (author's transl)].

Seven saccular coronary artery aneurysms have been demonstrated in the course of 1452 selective coronary artery angiograms. In six patients they were arterio-sclerotic; in one patient the aneurysm must have been congenital or of mycotic-embolic origin. The differential diagnosis between true aneurysms and other causes of vascular dilatation is discussed.

[Computer tomography of aorto-coronary bypass (author's transl)].

Computer tomography is a non-invasive method for demonstrating occlusion or patency of an aorto-coronary bypass. The early results of computer tomographic investigations of 77 bypasses in 51 patients are described. CT diagnosis of bypass patency is well established, but further work will be required to determine the accuracy of computer tomographic diagnosis of bypass occlusion.
