Serum Magnesium Is Associated with Long-Term Survival of Non-ST-Elevation Myocardial Infarction Patients

Background: Low serum magnesium (sMg) is associated with cardiovascular risk factors and atherosclerotic disease. Objective: To evaluate the association between sMg levels on admission and clinical outcomes in hospitalized non-ST-elevation myocardial infarction (NSTEMI) patients. Methods: A retrospe...

description Background: Low serum magnesium (sMg) is associated with cardiovascular risk factors and atherosclerotic disease. Objective: To evaluate the association between sMg levels on admission and clinical outcomes in hospitalized non-ST-elevation myocardial infarction (NSTEMI) patients. Methods: A retrospective analysis of all patients admitted to a single tertiary center with a primary diagnosis of NSTEMI. Patients with advanced chronic kidney disease were excluded. Clinical data were collected and compared between lower sMg quartile patients (Q1; sMg < 1.9 mg/dL) and all other patients (Q2–Q4; sMg ≥ 1.9 mg/dL). Results: The study cohort included 4552 patients (70% male, median age 69 [IQR 59–79]) who were followed for a median of 4.4 (IQR 2.4–6.6) years. The median sMg level in the low sMg group was 1.7 (1.6–1.8) and 2.0 (2.0–2.2) mg/dL in the normal/high sMg group. The low sMg group was older (mean of 72 vs. 67 years), less likely to be male (64% vs. 72%), and had higher rates of comorbidities, including diabetes, hypertension, and atrial fibrillation (59% vs. 29%, 92% vs. 85%, and 6% vs. 5%; p < 0.05 for all). Kaplan–Meier survival analysis demonstrated significantly higher cumulative death probability at 4 years in the low sMg group (34% vs. 22%; p log rank <0.001). In a multivariable analysis model adjusted for sex, significant comorbidities, coronary interventions during the hospitalization, and renal function, the low sMg group exhibited an independent 24% increased risk of death during follow up (95% CI 1.11–1.39; p < 0.001). Conclusions: Low sMg is independently associated with higher risk of long-term mortality among patients recovering from an NSTEMI event.
