Experimental mRNA therapy promotes repair after heart attack damage

mRNA Therapy Shows Heart Repair Potential After Heart Attack

Researchers used mRNA to temporarily activate Myc and Cyclin T1 in mouse heart cells.
Treated mice pumped roughly 10% more blood per heartbeat than mock-treated mice after heart attack damage.
The work is preclinical and requires larger-animal and human studies.

One-third of Australians could benefit from preventive heart attack and stroke medications: New risk assessment

Australia’s heart-risk update expands preventive care discussion

The analysis covered more than 115,000 Australians aged 45–74 without prior heart disease or stroke.
The 2023 calculator classified 26.4% as intermediate risk, versus 11.6% under the 2012 tool.
The change may lead to more GP discussions about preventive treatment and lifestyle measures.

Cannabis use linked to higher heart attack risk during and after surgery, but fewer blood clots

Cannabis Use Tied to Higher Perioperative Heart Attack Risk

A five-study review of 44,312 patients associated cannabis use with a 46% higher perioperative heart-attack risk.
The review found no significant association with stroke, respiratory failure, kidney injury or death.
The authors said an observed lower venous-clot risk does not establish cannabis as protective.

EVAOLD trial provides guidance on treating older patients after a heart attack

EVAOLD trial bolsters routine invasive care for older NSTEMI patients

The EVAOLD trial, presented at ESC Congress 2026, found that routine invasive management should not be replaced with a selective, stress-test-guided approach in older NSTEMI patients.
The randomized trial enrolled patients aged 80 and older with NSTEMI and planned to test noninferiority of a stress-imaging-first strategy against routine invasive care.
At the first interim analysis, after 587 patients, the trial was stopped for futility because the conditional chance of demonstrating noninferiority was low.
The study's principal investigator, Professor Gilles Barone-Rochette, highlighted that benefit-risk uncertainty and complication risk had prompted the hypothesis that stress testing could act as a gatekeeper.

New global definition of myocardial infarction aims to improve diagnosis, treatment and patient understanding

Cardiology groups issue a new global definition for heart attacks

Four cardiac societies published the Fifth Universal Definition of Myocardial Infarction.
The revision replaces a harder-to-apply numerical framework with three clinical settings.
The new model links classification more directly to underlying cause and diagnostic evaluation.

Prior heart attack linked to faster declines in thinking and memory skills

Past heart attacks may accelerate cognitive decline over time, large study finds

Researchers followed more than 20,000 adults for 10 years.
Heart attack survivors had an average yearly 5% increased odds of developing cognitive impairment.
The association was reported as similar across Black and white adults and across men and women.
Silent heart attacks were also linked to faster cognitive decline.
