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...
متن کاملRelief 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...
متن کاملEffect of pre-treatment with transdermal glyceryl trinitrate on myocardial ischaemia during coronary angioplasty.
OBJECTIVE In the light of the reported inconsistent anti-ischaemic and antianginal effects of transdermal glyceryl trinitrate, its efficacy and influence on the effects of intracoronary glyceryl trinitrate were examined during coronary angioplasty, which provides a model of controlled, reversible ischaemia. DESIGN Double blind, randomised study of the effect of transdermal and intracoronary g...
متن کاملIncreased coronary sinus lactate concentration during pacing induced angina pectoris after clinical improvement by glyceryl trinitrate.
Ten patients with stable angina pectoris and obstructed coronary arteries (greater than 75% reduction in diameter) were studied before and during two periods of pacing, the second of which was preceded by sublingual administration of glyceryl trinitrate (mean dose 0.78 mg). Coronary sinus blood flow measurements and aortocoronary sinus blood sampling for metabolite determinations were carried o...
متن کاملPotential deleterious haemodynamic effects of glyceryl trinitrate on myocardial ischaemia in man.
The potential adverse effects of glyceryl trinitrate on myocardial ischaemia were studied using low and high dose infusions in 10 patients with coronary heart disease. Cardiac venous flow was measured by the thermodilution technique and blood was sampled for metabolic studies. Angina pectoris was provoked by atrial pacing before drug infusion and the same heart rate was regained with low and hi...
