Case against routine use of glyceryl trinitrate before coronary angiography.

to the degree of coronary narrowing, 47 consecutive chest pain patients were studied without premedication by analysing selective coronary angiograms before and after glyceryl trinitrate. Proximal coronary diameters were measured in superimposed frames with callipers. Lumen diameter increased after glyceryl trinitrate 15 ± 2 per cent in the left main, 18 ± 2 per cent in the left anterior descen...

Glyceryl trinitrate before coronary angiography.

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...

Pre-Hospital Glyceryl Trinitrate: Potential for Use in Intracerebral Hemorrhage

BACKGROUND Intracerebral hemorrhage is associated with poor clinical outcome and high mortality. Research and treatment modalities have focused on the expansion of the primary hematoma through blood pressure control and activation of coagulation factors. However, clinical trials have failed to show decreased rates of death or disability in intracerebral hemorrhage following hospital initiation ...

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 ...
