BACKGROUND: Serum magnesium levels are usually measured and corrected, if warranted, among patients with cardiac diseases.
OBJECTIVE: To determine the rate of and clinical factors associated with hypomagnesemia among patients with cardiac conditions.
DESIGN: Cross-sectional study.
SETTING: Davao Regional Medical Center (DRMC) in Tagum City, Philippines, from January 2014 to January 2016.
PARTICIPANTS: 59 males and 53 females with cardiac diagnoses and serum magnesium level determination results.
MAIN OUTCOME MEASURES: Rate of hypomagnesemia, odds ratios (95% CI) of having hypomagnesemia for selected clinical factors.
MAIN RESULTS: The mean age of the patients was 60.72 ± 16.73 years. The mean serum magnesium level was 0.75 ± 0.23 mmol/L, and 47/112 (41.96%) had hypomagnesemia (serum magnesium
CONCLUSION: In this study, 41.96% of the patients had hypomagnesemia. COPD and stroke comorbidities, diuretic therapy, and atrial fibrillation among patients with cardiac conditions were all significantly associated with hypomagnesemia.
