Gated cardiac blood pool scans were obtained using a single crystal Anger camera with a general purpose collimator. In vivo labelling of the red blood cells with 20 mCi of technetium activity was done and a best septal view was obtained. The acquired data were processed using an Elscint AQ-75, DPT-3 acquisition unit equipped with the Dycom-80 program. Each cardiac cycle was divided into 24 fram...

BACKGROUND Previous studies have shown that intracoronary nitroprusside injection is safe and effective after slow reflow complicates percutaneous coronary intervention (PCI). OBJECTIVES We sought to determine the safety and efficacy of selective intracoronary administration of nitroprusside through the drug delivery catheter before balloon dilatation to prevent no or slow reflow during PCI f...

The acute hemodynamic effects of dobutamine and nitroprusside were compared in 19 patients with low output cardiac failure. At dosage levels yielding similar increases in cardiac index (12 patients), nitroprusside resulted in significantly lower arterial systolic and wedge pressures and did not increase heart rate suggesting advantages over dobutamine when reduction in myocardial oxygen require...

OBJECTIVE To report a case of erythromelalgia in an adolescent patient successfully treated with nitroprusside. CASE SUMMARY A 15-year-old girl with erythromelalgia resistant to aspirin therapy received an infusion of nitroprusside. The response of the erythromelalgia to nitroprusside was dramatic, with complete pain resolution within 17 hours after the start of therapy. No relapse of erythro...

The present study was designed to test the hypothesis that i.v. nitroglycerin is as effective as sodium nitroprusside for managing acute hypertension early after coronary artery bypass surgery. Seventeen patients received both nitroglycerin and nitroprusside in a randomized crossover protocol. Infusion rates were increased stepwise to lower mean arterial pressures comparably with each drug. In ...
