Ozempic-style drugs could slash complication risks after heart attacks, research suggests

A fashionable people of weight-loss drugs whitethorn forestall life-threatening cardiac complications by opening microscopic humor vessels that often stay blocked aft a bosom attack, according to a survey published this week successful Nature Communications.

The research, led by the University of Bristol and University College London, identified a biologic brain-gut-heart signaling pathway. 

This find appears to explicate however GLP-1 drugs — which mimic glucagon-like peptide-1, a hormone that helps modulate humor sweetener and appetite — support bosom insubstantial from a information known arsenic "no-reflow."

"In astir fractional of each bosom onslaught patients, tiny humor vessels wrong the bosom musculus stay narrowed, adjacent aft the main artery is cleared during exigency aesculapian treatment," Dr. Svetlana Mastitskaya, the study’s pb writer and a elder lecturer astatine Bristol Medical School, said successful a property release.

"This results successful a complication known arsenic ‘no-reflow,’ wherever humor is incapable to scope definite parts of the bosom tissue."

This deficiency of humor travel increases the hazard of bosom nonaccomplishment and decease wrong a year. GLP-1 medications could forestall this, according to the researchers.

How it works

When the GLP-1 hormone is released successful the gut oregon administered arsenic a drug, it sends a awesome to the brain, which past sends a awesome to the bosom that switches connected peculiar potassium channels successful tiny cells called pericytes.

When these channels open, the pericytes relax, which allows the tiny humor vessels (capillaries) to widen and amended humor travel to the bosom muscle, the researchers noted.

The caller survey utilized carnal models and cellular imaging to way however GLP-1 interacts with bosom tissue. When the researchers removed the potassium channels, the drugs nary longer protected the bosom — confirming they play a cardinal role.

The findings suggest that existing GLP-1 medications, already utilized for benignant 2 diabetes and obesity, could beryllium repurposed arsenic exigency treatments. (iStock)

The researchers noted respective limitations, including that the survey relied connected carnal models.

Clinical trials are indispensable to find whether the brain-gut-heart pathway operates with the aforesaid timing and efficacy successful humans.

While the survey highlights the drug's contiguous benefits during a bosom attack, it des not found whether semipermanent usage of these drugs provides a pre-existing level of protection. (iStock)
