Some acute and chronic viral infections linked to increased risk of cardiovascular disease

In the weeks following a bout of influenza or COVID, the risk of heart attack or stroke may rise dramatically, and chronic infections such as HIV may increase the long-term risk of serious cardiovascular disease events, according to new, independent research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

How branding and peer pressure keep kids hooked on energy drinks

Children and adolescents in North East England still find energy drinks easy to access despite a voluntary UK ban, drawn by taste, price, and powerful marketing. Hydration drinks like PRIME are viewed as “healthier,” even though young consumers often misunderstand their ingredients and health impacts.

Women gain stronger heart protection from exercise than men, study reveals

Researchers analyzing over 85,000 UK Biobank participants found that women gain greater cardiovascular benefits from physical activity than men, needing only half the exercise to achieve similar reductions in coronary heart disease and mortality risk. The study underscores the importance of sex-specific guidelines for CHD prevention.

Study highlights non-inferiority of super-high-pressure non-compliant balloons in coronary interventions

New study findings show that utilizing super-high-pressure non-compliant balloons (NCB) is non-inferior to intravascular lithotripsy (IVL) balloon catheters for lesion preparation and stent expansion in severely calcified lesions during percutaneous coronary intervention (PCI).

Landmark trial shows drug-eluting balloon as effective option for in-stent restenosis

Results from the first randomized clinical trial in the United States to compare a sirolimus-eluting balloon (DEB) to control group consisting of drug-eluting stent (DES) and balloon angioplasty (BA) for the treatment of bare-metal and DES in-stent restenosis (ISR) deemed DEB to be noninferior to conventional therapies.

Cutting balloon angioplasty proves noninferior to intravascular lithotripsy in treating calcified coronary lesions

Results from the first randomized controlled trial to directly compare the safety and efficacy of cutting balloon (CB) angioplasty to intravascular lithotripsy (IVL) prior to drug-eluting stent (DES) implantation for the treatment of calcified coronary artery disease found CB to be noninferior to IVL.
