<p>Microvascular impairment in women with signs and symptoms of ischemia was predictive of adverse cardiovascular outcomes, a new analysis suggests.<p>The study researchers, <a href="http://www.onlinejacc.org/content/73/6/684">publishing</a> in the <em>Journal of the American College of Cardiology,</em> included 224 women from the Women&rsquo;s Ischemia Syndrome Evaluation (WISE) study with and without obstructive coronary artery disease and signs and symptoms of ischemia; the study population then underwent coronary reactivity testing. The researchers obtained coronary flow reserve and coronary blood flow data, and tested epicardial coronary reactivity by dilation response to intracoronary acetylcholine and intracoronary nitroglycerin. The primary study endpoints were major adverse cardiovascular events (MACE), including cardiovascular death, <a href="https://proddocwire.wpengine.com/tag/myocardial-infarction/">myocardial infarction</a>, <a href="https://proddocwire.wpengine.com/tag/stroke/">stroke</a>, and <a href="https://proddocwire.wpengine.com/abstracts/cardiology-abstracts/acute-heart-failure-hospitalizations/">heart failure</a>. Mean follow-up was 9.7 years.</p><blockquote class="twitter-tweet" data-width="500" data-dnt="true">

According to the results, low coronary flow reserve was a predictor of higher MACE rates (P=0.021), and low coronary blood flow was predictive of an increased mortality risk (P=0.038), as well as an increased risk for MACE (P=0.006) after adjustment for cardiovascular risk factors. While there was no association between epicardial intracoronary nitroglycerin, a decrease in cross-sectional area in response to intracoronary acetylcholine was associated with a greater risk for angina hospitalization (P&lt;0.0001).</p><blockquote class="twitter-tweet" data-width="500" data-dnt="true">
