Prognostic Value of Systemic Endothelial Dysfunction in Patients With Acute Coronary Syndromes: Further Evidence for the Existence of the “Vulnerable” Patient

Fichtlscherer, Stephan, Breuer, Susanne, Zeiher, Andreas M.·2004·Circulation

Abstract

Background— Endothelial vasodilator dysfunction may serve as a marker integrating the vascular risk of an individual; however, whether systemic vasodilator function predicts disease progression and cardiovascular event rates in patients with manifest acute coronary syndromes (ACS) is unknown. Methods and Results— In 198 patients with angiographically documented ACS, forearm blood flow (FBF) responses to acetylcholine (ACH; 10 to 50 μg/min) and sodium nitroprusside (SNP; 2 to 8 μg/min) were measured by venous occlusion plethysmography before hospital discharge within 5 days of an episode of an ACS. Cardiovascular events (cardiovascular death, myocardial infarction, and ischemic stroke) served as outcome variables over a mean follow-up period of 47.7±15.1 months. Patients who experienced cardiovascular events during follow-up (n=31) had a significantly reduced vasodilator response to ACH ( P <0.05) and SNP ( P <0.05). By multivariate analysis, vasodilator response to ACH and elevated troponin T serum levels were the only significant ( P <0.05) independent predictors of a poor prognosis, even after adjustment for traditional cardiovascular risk factors, concurrent medication, invasive treatment strategy, and C-reactive protein serum levels. Recovery of endothelium-dependent vasoreactivity as assessed by repeated FBF assessment 8 weeks after the index measurement after the ACS predicted further event-free survival in a subset of 78 patients. Conclusions— Systemic endothelium-dependent vasoreactivity predicts recurrence of instability and cardiovascular event rates in patients with ACS. Furthermore, the recovery of systemic endothelial function is associated with event-free survival. Assessment of systemic vasoreactivity, measured by a minimally invasive test, provides important prognostic information in addition to that derived from traditional risk factor assessment in patients with ACS.

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.
