Frequency of hypomagnesemia in patients presenting with acute coronary syndrome.

Abstract

Objective: To assess the rate of hypomagnesemia in patients presenting with ACS in a local population. Study Design: Cross Sectional Descriptive study. Setting: Faisalabad Institute of Cardiology (FIC), Faisalabad. Period: 17^th January 2022 to 16^th July 2022 (six months). Methods: Nonprobability consecutive sampling was used to enroll 185 ACS patients, aged 35–80 years. Excluded patients were those on diuretics, alcoholics or with malabsorption. Hypomagnesemia was defined as serum magnesium levels below normal range (1.7 to 2.5 mg/dl) and were measured in all patients. Chi square tests were used to explore the relationships of the data through SPSS version 21. Results: A total of 185 patients (mean age 57.67±10.70 years, 65.4% male) had a mean serum magnesium level of (1.81±0.31 mg/dl). Out of 185 patients, hypomagnesemia was seen in 34 (18.4%) patients. Prevalence was 21.1% in unstable angina, 15.4% in STEMI, and 20.3% in NSTEMI, with no significant association (p=0.665, across ACS types). No significant correlation was seen between hypomagnesemia and age, gender, and BMI (p>0.05). Conclusion: Hypomagnesemia was seen in (18.4%) of ACS patients, and no significant correlation was seen with demographic or clinical characteristics. Hypomagnesemia in ACS patients merits routine screening to help identify high-risk individuals so that management strategies can be guided.
