Abstract
BACKGROUND: Magnesium is one of the most abundant cations in the body and plays a vital role in the function of the cardiovascular system. Hypomagnesemia can cause severe and dangerous cardiovascular complications. Also, since drugs that can lead to hypomagnesemia are commonly prescribed to cardiac patients, we decided to investigate the prevalence of hypomagnesemia in the population of cardiac patients to be aware of the prevalence of this condition as an important risk factor for cardiovascular events. MATERIALS AND METHODS: This study is a retrospective cross-sectional study of an analytical-observational type with a fundamental-applied approach, in which by recording the information of patients in pre-designed forms, the prevalence of hypomagnesemia in them and also the prevalence of hypomagnesemia separation of different heart diseases and the relationship of hypomagnesemia with age, sex, glomerular filtration rate (GFR), and drugs used have been evaluated. RESULTS: A total of 982 patients were included in the study, of which 636 were men and 346 were women. The average age of the patients in this study was 63 years. Hypomagnesemia was observed in 138 patients (14%), and the prevalence of hypomagnesemia in patients with ventricular arrhythmias was 40%. It was also observed that only 47% of the patients with hypomagnesemia received magnesium, and the rest were not treated. CONCLUSION: This study highlights the importance of magnesium status and its relationship with various clinical factors in the studied population. This emphasizes the need to increase attention to hypomagnesemia, especially among vulnerable groups such as women and older adults.
