Background
Acute myocardial infarction (AMI) is the main cause of global and in-hospital mortality in patients with cardiovascular diseases. We aimed to examine the association between the coronary artery involved and the in-hospital mortality in patients who underwent primary percutaneous coronary intervention (pPCI) after ST segment elevation myocardial infarction (STEMI).
Methods
The in-hospital mortality of STEMI patients who underwent pPCI was assessed at the Department of Cardiology, Harzklinik Goslar, Germany, which has no access to immediate mechanical circulatory support (MCS), between 2013 and 2017.
Results
We enrolled 312 STEMI patients, with a mean age of 67.1 ± 13.4 years, of whom 211 (68%) were male. In-hospital mortality was documented in 31 patients (10%). In-hospital mortality was associated with pre-hospital cardiopulmonary resuscitation (CPR; n = 39/12.5%), older age, lower systolic blood pressure, Killip class > 1, triple-vessel disease (each p < 0.0001), female gender (p = 0.0158), and with the localization of the treated culprit lesion in the left main coronary artery (LMCA; p = 0.0083) and in the ramus circumflexus (RCX; p = 0.0141).
Conclusion
In this monocentric cohort, all-cause in-hospital mortality of STEMI patients after pPCI was significantly higher in those patients with culprit lesions in the LMCA and in the RCX, which may prove to be a substantial novel risk factor for STEMI-related mortality. Increasing age and female gender may be interdependent risk factors for mortality in this patient population. Furthermore, our data highlight the importance of the availability of MCS options in pPCI centers for patients after CPR.
