Baseline clinical, angiographic and procedural characteristics, as well as in-hospital outcomes were prospectively collected among all patients undergoing primary PCI as part of the New York State PCIRS <a href="https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-biology/information-processing" title="Learn more about Information Processing">data collection</a>. Patients with a history of prior <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/bypass-surgery" title="Learn more about Bypass Surgery">bypass graft</a> surgery were older and had a history of <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/heart-failure" title="Learn more about Heart Failure">heart failure</a>, <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/hypertension" title="Learn more about Hypertension">hypertension</a>, <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/dyslipidemia" title="Learn more about Dyslipidemia">dyslipidemia</a>, and <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/diabetes-mellitus" title="Learn more about Diabetes Mellitus">diabetes</a>. The <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/left-anterior-descending-coronary-artery" title="Learn more about Left Anterior Descending Coronary Artery">left anterior descending coronary artery</a> was usually the culprit vessel in post PCI and revascularization naïve patients, whereas it was a <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/vein-graft" title="Learn more about Vein Graft">vein graft</a> in patients with a prior history of surgical bypass. In-hospital mortality rates were different in the three groups and there was no significant difference in major adverse cardiac and cerebrovascular events rates among the three groups (<em>p</em> = 0.87). Notably, revascularization-naïve patients had higher rates of <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/major-bleeding" title="Learn more about Major Bleeding">major bleeding</a> complications (<em>p</em> = 0.006). By multivariable analysis, only age (OR 1.03; CI = 1.0–1.06), a prior history of <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/congestive-heart-failure" title="Learn more about Congestive Heart Failure">congestive heart failure</a> (OR 4.36, CI = 1.04–18.38) and dyslipidemia (OR 0.32 CI = 0.15–0.64) were independent predictors of 12-month mortality. Prior revascularization had no impact on rates of <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/apoplexy" title="Learn more about Apoplexy">stroke</a>, death or MACCE.</p> </div> <div id="as0020"> <h3 id="st0025">Conclusions</h3> <p id="sp0055">Patients with acute STEMI and CS had similar in-hospital and one year mortality, stroke or major adverse cardiac and cerebrovascular events rates irrespective of their prior revascularization status.</p> </div>
