Abstract

In recent years, a growing body of evidence supports that vitamin D plays a crucial role in various cardiovascular diseases. Cardiac muscle cells have vitamin D receptors as well as calcitriol-dependent Ca(2+) binding protein. Therefore, the vitamin D may have an effect on cardiac function. In this research, we investigated the association between vitamin D status and dilated cardiomyopathy (DCMP). We compared serum 25-hydroxy-vitamin D3 (25OHD3) concentrations in 39 patients (mean age 50.4 ± 11.7 years, 15 women) with DCMP and in 35 healthy controls (mean age 54.6 ± 13.2 years, 17 women). Parathyroid hormone (PTH), calcium (Ca++), phosphorus, lipid profile, albumin and echocardiographic parameters (left-ventricular (LV) ejection fraction, LV fractional shortening, LV-end-diastolic and end-systolic dimensions) were measured in all study participants. The mean serum 25OHD3 concentrations in patients with the DCMP were significantly lower in compared to healthy controls (24.1 ± 10.4 ng/mL versus 41.4 ± 20.9 ng/mL, P < 0.0001). PTH concentrations were significantly higher in patients with DCMP in comparison with healthy controls (90.6 ± 29.8 pg/mL versus 49.1 ± 18 pg/mL, P < 0.0001). Additionally, we observed a significant negativ...Continue Reading

Cardiac Remodeling

Cardiac remodeling in response to a myocardial infarction is characterized by progressive ventricular dilatation, cardiac hypertrophy, fibrosis, and deterioration of cardiac performance. Discover the latest research on Cardiac Remodeling here.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
