Abstract

Background — Whether patients at increased risk can be identified from a relatively low-risk population by coronary vascular function testing remains unknown. We investigated the relationship between coronary endothelial function and the occurrence of acute unpredictable cardiovascular events (cardiovascular death, myocardial infarction, stroke, and unstable angina) in patients with and without coronary atherosclerosis (CAD). Methods and Results — We measured the change in coronary vascular resistance (ΔCVR) and epicardial diameter with intracoronary acetylcholine (ACh, 15 μg/min) to test endothelium-dependent function and sodium nitroprusside (20 μg/min) and adenosine (2.2 mg/min) to test endothelium-independent vascular function in 308 patients undergoing cardiac catheterization (132 with and 176 without CAD). Patients underwent clinical follow-up for a mean of 46±3 months. Acute vascular events occurred in 35 patients. After multivariate analysis that included CAD and conventional risk factors for atherosclerosis, ΔCVR with ACh ( P =0.02) and epicardial constriction with ACh ( P =0.003), together with increasing age, CAD, and body mass index, were independent predictors of adverse events. Thus, patients in the tertile with the best microvascular responses with ACh and those with epicardial dilation with ACh had improved survival by Kaplan-Meier analyses in the total population, as did those in the subset without CAD. Similar improvement in survival was also observed when all adverse events, including revascularization, were considered. Endothelium-independent responses were not predictive of outcome. Conclusions — Epicardial and microvascular coronary endothelial dysfunction independently predict acute cardiovascular events in patients with and without CAD, providing both functional and prognostic information that complements angiographic and risk factor assessment.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
