Background: In patients presenting with cardiac arrest in the setting of ST elevation myocardial infarction (STEMI), the influence of age and arrest type (shockable vs. non-shockable) on outcome in the percutaneous coronary intervention (PCI) era is incompletely understood.
Methods: Using a prospective STEMI database, we evaluated the influence of age and arrest type on baseline characteristics and outcome in patients with STEMI complicated by cardiac arrest. Cardiac arrest was classified as shockable (ventricular tachycardia/ventricular fibrillation) or non-shockable (asystole/pulseless electrical activity).
Results: From March 2003 – December 2014, 4511 consecutive patients were enrolled in our STEMI network including 499 patients (11%) with cardiac arrest prior to PCI. Of these, 441 (88%) had shockable rhythm while 58 (12%) had non-shockable rhythm. In those < 60 years old with cardiac arrest, there was a higher prevalence of cigarette smoking regardless of arrest type. Diabetes was more common in older patients with shockable rhythm. There was no correlation between cardiac arrest type and proximal vs distal coronary occlusion.
Conclusions: Among this contemporary STEMI population, 40% of patients with shockable and non-shockable arrest were younger than 60 years, more than two thirds of whom were smokers. A non-proximal coronary culprit was present in nearly one third of patients. Hospital mortality was significantly associated with older age in both shockable and non-shockable rhythm.
