No Value In Adding Amino Acids After A Heart Attack

No Value In Adding Amino Acids After A Heart Attack
Some physicians believed that adding nutritional supplement with amino acids following a heart attack may improve the chances of surviving a heart attack or decreasing the complications related to a heart attack.

New research is showing that this belief has no scientific backing. This research has shown that use of the amino acid supplement L-arginine following a heart attack does not improve cardiac functions following a heart attack. You can find these results on the latest edition of the Journal of Medical Association.

L-arginine is a widely available dietary supplement and is publicized as having benefits for patients with hypertension, angina, heart failure and sexual dysfunction, according to background information in the article. Previous studies suggest that L-arginine has the potential to reduce vascular (blood vessel) stiffness.

This randomized, double-blind, placebo-controlled trial included 153 STEMI patients; 77 were 60 years or older. Participants were enrolled from February 2002 to June 2004. Patients were randomly assigned to receive L-arginine (goal dose of 3 g three times a day) or matching placebo for six months.

The scientists found that 6 months of L-arginine added to standard postinfarct medications did not reduce noninvasive measures of vascular stiffness, improve ejection fraction, or improve clinical outcomes.

To the contrary, we noted a possible increased risk of death in older patients after infarction while taking L-arginine compared with those taking a placebo, leading to the early termination of the study. These findings have broad public health implications given the increasing availability and use of L-arginine in patients with and without established cardiovascular diseases.

Heart disease
About 13 million Americans (about 7 percent of the total population) suffer from coronary artery disease. Coronary artery disease is the leading cause of death in American men and women amounting a staggering 20 percent of all causes of death. About half of all deaths related to cardiovascular diseases occur from coronary artery disease. Through this heart watch blog we will have our humble contribution towards making men and women aware of the risks of heart diseases.
