Capillaries form new vessels after heart attacks
A recent study conducted by Chinese researchers on rats has confirmed that the formation of new blood vessels after heart attacks primarily occurs from small capillaries rather than from large, thick-walled arteries. This finding contradicts the previous prevailing belief that new vessels form from collateral coronary arteries that widen in response to increased blood flow following an obstruction. The results showed that most of the new vessels originate from cells lining the capillaries, and stimulating the protein V.E.G.F-A significantly increases the formation of collateral arteries and helps improve heart recovery. This discovery opens new prospects for more effective heart treatments based on novel molecular pathways.
