Abstract:
Objective:To explore influence of position of myocardial infarction and coronary artery lesions in patients with acute ST elevation myocardial infarction (STEMI) ,and the relationship among heart failure ,arrhythmia and severity of coronary artery lesion .Methods :Clinical data of 224 patients ,who hospitalized in our hospital because of STEMI and received coronary angiography from Jan 2009 to Jun 2011 ,were retrospectively analyzed .General data of patients were collected ,and SYNTAX score was used to reflect severity of coronary artery lesion ,and the rela‐tionship among heart failure ,arrhythmia and SYNTAX scores were analyzed .Results:Incidence rate of heart fail‐ure in patients with infarction relate artery left anterior descending artery (LAD) AND/or left main coronary artery (LM) was significantly higher than that of patients with right coronary artery (RCA) (57.0% vs .39.7% , P=0.017) ,incidence rate of arrhythmia in patients with RCA was significantly higher than that of patients with left circumflex artery (LCX) (37.0% vs .6.3% , P=0.016);incidence rates of arrhythmia (48.4% ) ,shock (54.8% ) were highest in patients with inferior wall/right ventricle than those of other position , P<0.05 or <0.01.SYNTAX scores in patients with heart failure and arrhythmia were significantly higher than those of patients without heart failure and arrhythmia respectively [ (18.7 ± 9.1) scores vs .(15.4 ± 8.6) scores ,(19.7 ± 9.0) scores vs .(16.1 ± 8.8) scores , P<0.01 both] .Conclusion:Incidence rates of heart failure ,cardiogenic shock and arrhythmia are related to coronary artery lesions position and degree and myocardial infarction position in STEMI patients .
