Sublingual glyceryl trinitrate compared with Nitrolingual spray using cardiac scintigraphy.

Patients' knowledge of sublingual glyceryl trinitrate.

of stones from the gall bladder.3 There are several clinical implications. The long contiguous course of the cystic duct and common hepatic duct could explain why surgeons sometimes inadvertently leave a long remnant of cystic duct, which is reputedly a cause of the postcholecystectomy syndrome.4 Furthermore, the migration of stones from the gall bladder into the contiguous segment may explain ...

Comparison with glyceryl trinitrate

The coronary haemodynamic effects of nifedipine and glyceryl trinitrate were compared in 22 patients undergoing investigations for suspected coronary artery disease. Myocardial blood flow was estimated by the coronary sinus thermodilution technique. In sinus rhythm nifedipine increased mean coronary sinus flow from 135 ml/min to 152 m/min, and reduced arterio-coronary sinus oxygen difference fr...

Glyceryl trinitrate before coronary angiography.

Relief by intracoronary glyceryl trinitrate of coronary artery spasm resistant to sublingual route of administration.

Inappropriate percutaneous transluminal coronary angioplasty of the anterior descending artery was avoided in a 52-year-old woman when the intracoronary administration of glyceryl trinitrate immediately before the angioplasty disclosed the organic component of the supposedly fixed, critical (80%) stenosis to be less than 50% of the lumen diameter. The spastic component of the stenosis had not b...

Comparing two different protocols for tilt table testing: sublingual glyceryl trinitrate versus isoprenaline infusion.

OBJECTIVE To assess the diagnostic value and safety of sublingual glyceryl trinitrate tilt testing compared with isoprenaline infusion in patients with unexplained syncope. DESIGN Glyceryl trinitrate and isoprenaline tilt tests were performed in two successive days on a random basis in cases and controls. SETTING Outpatient cases with syncope referred to Shahid Rajaii Heart Hospital. SUBJ...
