Sunshine can do more than just lift your mood and release stress. It's one of the best natural sources of Vitamin D, which is responsible in various ways to ensure the well-being of human beings. A recent study conducted on mice has found that regular consumption of vitamin D can reduce risk of heart failure after someone has suffered from a heart attack. The results of the study have been published in the journal Heart Lung and Circulation. Heart failure is a fatal condition that affects over 20 million people all over the world.

The study that was titled, "Vitamin D Improves Cardiac Function After Myocardial Infarction Through Modulation of Resident Cardiac Progenitor Cells", concluded that consuming the nutrient after a heart attack may save the patient. "Vitamin D has been implicated in the prevention of heart failure. However, the underlying mechanism remains unclear", said the authors of the study, in a report in the journal. Vitamin D may prevent excessive scarring and thickening of heart tissue, thus cutting the risk of heart failure following a heart attack.

James Chong, Associate Professor at the Westmead Institute for Medical Research in Australia said, "This is a problem because scarring of heart tissue can reduce the heart's ability to pump blood effectively, which can lead to heart failure." The researchers tested the impact of a form of vitamin D- 1,25D. This form of the vitamin interacts with hormones and acts on the cardiac colony-forming unit fibroblasts (cCFU-Fs)cells, which are responsible for forming scar tissue following a heart attack.

Chong said that the research discovered that Vitamin D actually blocks the cCFU-Fs from forming scar tissue and hence, plays an important role in lowering the risk of heart failure in patients who have suffered heart attack or myocardial infarction.

"The benefits of Vitamin D are becoming increasingly known, but we still don't fully understand how mechanistically it can help with heart disease management. We wanted to know more about how Vitamin D protects the heart after a heart attack", added Chong.
