Researchers discover how Resveratrol repairs and regenerates cardiac tissues following a heart attack
(Myocardial Infarction)

05/04/2007:

A heart attack may result in damaged heart muscle.  Various methods are used to encourage the formation of new blood vessels to re-oxygenate and repair damaged cardiac tissues following a heart attack.  While cardiac bypass surgery is an effective way of doing this, in about 20 percent of cases blood flow cannot be adequately restored to regions of the heart. 

In a study of rats, following an induced heart attack, rats given the human equivalent of 70 milligrams of oral resveratrol, experienced more complete repair and regeneration of damaged tissues. 

In the chart below, the CMI group (control group, myocardial infarction, or heart attack) of rats were untreated.   The RMI group (resveratrol, after myocardial infarction) were treated with resveratrol.  The effects of resveratrol on capillary density (formation of new blood vessels) and blood flow were obviously improved in the resveratrol-treated animals following an experimentally-induced heart attack.
