Influence of Perioperative Serum Magnesium for Cardiac and Noncardiac Morbidity and Mortality Following Emergency Peripheral Vascular Surgery

To examine the influence of serum magnesium on 30-day mortality and cardiac and noncardiac morbidity. Retrospective cross-sectional observational study of routinely collected prospective data. Single-center tertiary vascular center in the United Kingdom. All patients undergoing arterial peripheral vascular surgery during an unplanned admission. Observational, no interventions implemented. In the study, n = 197. One hundred thirty-eight were male (70.1%). Median age at procedure was 70.0 years (interquartile range 20.0). Of those with a documented history, 37.9% had diabetes, 81.7% had a smoking history, 63.7% had hypertension, and 26.5% had known ischemic heart disease or heart failure. There was a significant perioperative change in magnesium (p < 0.001), calcium (p
