Introduction: To the best of the authors’ knowledge, very few publications are available which report on the prognostic significance of the culprit vessel in patients with ST elevation myocardial infarction treated with successful primary percutaneous coronary intervention. Aim: The aim of the authors was to obtain data on the significance of the culprit vessel in patients with ST elevation myocardial infarction treated successfully by primary percutaneous coronary intervention. Method: The authors performed a retrospective study in 10,763 patients with ST elevation myocardial infarction who underwent successful primary percutaneous coronary intervention. The culprit vessels were the left main artery, left anterior descendent artery, left circumflex artery, and right coronary artery. The authors constructed univariate survival curves for different culprit vessels and also performed multivariate modelling of time-to-death, controlling for age, sex, and comorbidities. Results: The majority of the culprit lesions were found in the left anterior descendent artery (44.3%), the right coronary artery (40.9%), and the left circumflex artery (13.7%). The culprit vessel was overall a highly significant (p<0.0001) factor of survival, with right coronary artery exhibiting a highly significantly better prognosis (hazard ratio 0.69, 95% CI 0.61–0.79, p<0.0001) and left main artery exhibiting a significantly worse prognosis (hazard ratio 1.56, 95% CI 1.04–2.35, p = 0.0321) than the reference vessel (left anterior descendent artery). Conclusion: These data demonstrate that the culprit vessel has independent prognostic significance. Orv. Hetil., 2016, 157(32), 1282–1288.

Abstract Background Isolated right ventricular myocardial infarction (RVMI) due to a recessive right coronary artery (RCA) occlusion is a rare presentation. It is typically caused by right ventricle (RV) branch occlusion complicating percutaneous coronary intervention. We report a case of an isolated RVMI due to flush RCA occlusion presenting via our primary percutaneous coronary intervention ST-elevation myocardial infarction pathway. Case summary A 61-year-old female smoker with a history of hypercholesterolaemia presented via the primary percutaneous coronary intervention pathway with sudden onset of shortness of breath, dizziness, and chest pain while walking. Transradial coronary angiography revealed a normal left main coronary artery, large left anterior descending artery that wrapped around the apex and dominant left circumflex artery with the non-obstructive disease. The RCA was not selectively entered despite multiple attempts. The left ventriculogram showed normal left ventricle (LV) systolic function. She was in cardiogenic shock with a persistent ectopic atrial rhythm with retrograde p-waves and stabilized with intravenous dobutamine thus avoiding the need for a transcutaneous venous pacing system. A computed tomography pulmonary angiogram demonstrated no evidence of pulmonary embolism while an urgent cardiac gated computed tomography revealed a recessive RCA with ostial occlusive lesion. A cardiac magnetic resonance imaging confirmed RV free wall infarction. She was managed conservatively and discharged to her local district general hospital after 5th day of hospitalization at the tertiary centre. Discussion This case describes a relatively rare myocardial infarction presentation that can present with many disease mimics which can require as in this case, a multi-modality imaging approach to establish the diagnosis.
