Serious cardiac adverse events after decompressive craniectomy for malignant cerebral infarction

There is a significant association between cardiac dysfunction and ischemic stroke. The serious cardiac adverse events (SCAEs) after decompressive craniectomy for malignant cerebral infarction from ischemic stroke were studied retrospectively. Retrospective data were collected for preexisting cardiac risk factors, baseline clinical measures, and perioperative SCAEs including life-threatening arrhythmias, myocardial ischemia, cardiac failure, and cardiac arrest. The association between perioperative SCAEs and mortality was assessed using the χ(2) test. Data from 42 patients were analyzed. Mortality occurred in 19 (45.2%) patients. Eleven (57.9% of deaths) suffered mortality because of neurological causes, 7 patients (36.8% of mortality) because of cardiac causes, and 1 because of other causes. Mortality in patients who developed SCAEs was significantly higher than in those without SCAEs [75% mortality with SCAEs vs. 18.2% without SCAEs (P
