Because the endothelial nitric oxide synthase (eNOS) T-786C polymorphism is associated with reduced nitric oxide production and coronary artery spasm in Japanese patients, we speculated that it might be reversibly associated with Prinzmetal’s variant angina in white Americans. Polymerase chain reaction analyses of eNOS T-786C and stromelysin 5A6A polymorphisms were done in 31 women and 12 men (42 white and 1 black American, median age 50 years), with well-documented Prinzmetal’s variant angina. We matched each case with 1 healthy control by race and gender. Of the 43 cases, 21 (49%) were homozygous for wild-type normal eNOS, 19 (44%) were T-786C…
