Study of Serum Calcium Levels in Diabetes Mellitus and Its Association with Left Ventricular Remodelling
INTRODUCTION: Diabetes mellitus, a prevalent metabolic disorder, not only affects organ function but also induces significant metabolic abnormalities, including disturbances in calcium homeostasis. Left ventricular hypertrophy identified as a threatening prognostic sign and an independent risk factor for cardiac death, coronary heart disease, ventricular dysrhythmias, and heart failure, is prevalent in type 2 diabetes mellitus (T2DM). The association between T2DM and LVH persists even in the absence of hypertension and obesity, suggesting additional contributing factors beyond traditional risk factors. This study explores the potential role of altered calcium homeostasis, indexed by serum calcium levels, in contributing to LVH prevalence in T2DM patients. MATERIALS AND METHODS: A cross sectional study conducted among Diabetic patients presenting to outpatient department and patients admitted in Medicine department, Government Medical College, Nizamabad, Telangana, India. All the design, analysis, interpretation of data, drafting and revisions followed the “Strengthening the Reporting of Observational Studies in Epidemiology” (STROBE) guidelines and the study was based on Declaration of Helsinki. History of myocardial infarction, coronary artery bypass or angioplasty, atrial fibrillation, moderate to severe valvular heart disease, stroke or occlusive peripheral vascular disease, heart failure. CBP (complete blood picture), RFT (renal function tests), LFT (liver function tests), Serum calcium, total cholesterol, triglycerides, low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), FBS, PLBS, HBA1C. RESULTS: Overview of the distribution of study participants based on the presence or absence of Left Ventricular Hypertrophy (LVH). The data reveals a nearly equal distribution, with 51% of participants exhibiting LVH and 49% showing its absence. The age distribution of study participants stratified based on the presence or absence of Left Ventricular Hypertrophy (LVH). The results indicate insignificant associations between age groups and the occurrence of LVH (p=0.012). In the 40-49 age category, 23.8% of participants with LVH were observed, compared to 23.8% without LVH. Among individuals aged 50-59, 52.4% with LVH were noted, compared to 51.5% without LVH. Similarly, in the 60-69 age group, 19% had LVH, and 20.8% did not. For those aged 70 and above, 4.8% exhibited LVH, compared to 3.9% without LVH. CONCLUSION This study contributes valuable insights into the complex pathophysiology of cardiac complications in T2DM, emphasizing the importance of comprehensive cardiovascular risk assessment that includes serum calcium evaluation. Future research exploring mechanisms underlying the association between calcium dysregulation and LVH could potentially lead to novel therapeutic strategies aimed at reducing cardiovascular morbidity and mortality in diabetic populations.
