Study Explains How Heart Attack Can Lead To Heart Rupture

For people who initially survive a heart attack, a significant cause of death in the next few days is cardiac rupture -- literally, bursting of the heart wall.

A new study by University of Iowa researchers pinpoints a single protein as the key player in the biochemical cascade that leads to cardiac rupture. The findings, published as an Advance Online Publication (AOP) of the journal Nature Medicine, suggest that blocking the action of this protein, known as CaM kinase, may help prevent cardiac rupture and reduce the risk of death.

Heart Protection From Component Of Garlic Oil

A component of garlic oil may help release protective compounds to the heart after heart attack, during cardiac surgery, or as a treatment for heart failure.

At low concentrations, hydrogen sulfide gas has been found to protect the heart from damage. However, this unstable and volatile compound has been difficult to deliver as therapy.

Now researchers at Emory University School of Medicine have turned to diallyl trisulfide, a garlic oil component, as a way to deliver the benefits of hydrogen sulfide to the heart. Their findings suggest that doctors could use diallyl trisulfide in many of the situations where researchers have proposed using hydrogen sulfide.

Excessive Amounts Of Vitamin D Linked To Onset Of Atrial Fibrillation

Vitamin D SupplementsWhile previous studies have linked vitamin D deficiency to an increased risk for cardiovascular disease, new research at the Intermountain Medical Center Heart Institute shows that too much vitamin D can lead to the onset of a dangerous heart condition known as atrial fibrillation.

Researchers at Intermountain Medical Center, the flagship facility for the Intermountain Healthcare system, studied more than 132,000 patients and found the risk of developing atrial fibrillation was two and a half times greater in those with excess levels of vitamin D compared to patients with normal levels.
