Scientists found that weight loss drugs similar to Ozempic can help prevent serious heart damage after a heart attack. These drugs may improve blood flow in the heart and reduce the risk of complications.
Researchers from the University of Bristol and University College London (UCL) studied how these GLP-1 weight-loss medications work on the heart. They found that these drugs can help prevent 'no-reflow', a condition where tiny blood vessels within the heart muscle remain narrowed after a heart attack.
The team discovered that GLP-1 drugs activate potassium channels, which relax small contractile cells called pericytes and allow previously constricted blood vessels to widen. This improves blood flow in the heart and reduces the risk of additional damage.
According to Dr. Svetlana Mastitskaya, lead author of the study, these findings suggest that GLP-1 drugs may offer a new strategy to improve recovery after a heart attack.
Why It Matters
This breakthrough could lead to new treatments for heart attack patients in India, where cardiovascular disease is a significant health concern. With timely and effective treatment, many lives could be saved or improved.
