Thus, cardiovascular functions may be affected by the impact of the vitamin D in the body. The down regulation of PTH is an essential factor that will make vitamin D has a positive influence on heart function. However, long term vitamin D deficiency can rise the production of PTH. This over production of PTH can cause valvular calcification, cardiac arrhythmia, arterial hypertension, myocardial calcification, and left ventricle hypertrophy. Vitamin D deficiency also can increase the rate of renin-angiotensin system. It has an important function in controlling blood pressure, electrolyte balance, and intravascular volume. However, vitamin D can affect heart function through influencing cardiomyocyte cell cycle rather than hormone system. Vitamin D can affect the cardiomyocyte through its receptors then it will suppress cardiac cells proliferation and to protect the function and structure of
