Cardiovascular events (cardiovascular death, unstable angina, myocardial infarction, percutaneous transluminal coronary angioplasty, coronary bypass grafting, ischemic stroke, or peripheral artery revascularization) served as outcome variables over a median follow-up period of 7.7 years. Patients suffering from cardiovascular events during follow-up (n=16) had significantly increased vasoconstrictor responses to acetylcholine infusion (\n                    <jats:italic>P<\/jats:italic>\n                    =0.009) and cold pressor testing (\n                    <jats:italic>P<\/jats:italic>\n                    =0.002), as well as significantly blunted vasodilator responses to increased blood flow (\n                    <jats:italic>P<\/jats:italic>\n                    &lt;0.001) and the intracoronary injection of nitroglycerin (\n                    <jats:italic>P<\/jats:italic>\n                    =0.001). Impaired endothelial and endothelium-independent coronary vasoreactivity were associated with a significantly higher incidence of cardiovascular events by Kaplan-Meier analysis. By multivariate analysis, all tests of coronary vasoreactivity were significant, independent predictors of a poor prognosis, even after adjustment for traditional cardiovascular risk factors or the presence of atherosclerosis itself.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Conclusions<\/jats:italic>\n                    \u2014Coronary endothelial vasodilator dysfunction predicts long-term atherosclerotic disease progression and cardiovascular event rates.
