Major adverse cardiac events and in‐hospital mortality was also significantly higher for those in Group I (P < 0.02 for both). A significant correlation was found between in‐hospital mortality and those in Group I (P = 0.03, OR: 6.27, CI: 1.22–32.3). There was an independent relationship between in‐hospital mortality and V<sub>4</sub>R‐ST elevation (P = 0.03, OR: 11.64, CI: 1.3–27.4).</p> </sec> <sec id="anec12199-sec-0040" sec-type="section"> <title>Conclusion</title> <p>ST segment elevation in chest lead V<sub>4</sub>R is associated with multivessel disease and increased in‐hospital mortality in patients with anterior STEMI that had undergone primary percutaneous coronary intervention to the left anterior descending artery.</p> </sec> </abstract>
