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...
