Nationwide study finds significant decline in treatment for heart attacks during pandemic

A nationwide study analyzing rates of percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) found a nearly 30% decline following the COVID-19 pandemic. STEMI cases have yet to recover to pre-pandemic levels, suggesting continued hesitation among patients to seek hospital care despite having a heart att...

Injured women half as likely as men to receive life-saving drug

A new study by the London School of Hygiene & Tropical Medicine found that injured women are half as likely as men to receive the life-saving drug TXA, despite the treatment being equally effective regardless of sex. The study highlights a significant disparity in trauma care, with clinicians needing clearer guidance to reduce bias.

Risk factors for dementia may vary with age

A new study finds that age-specific risk factors for dementia differ across various age groups. People around age 55 are more likely to develop dementia if they have diabetes or high blood pressure, while those in their 70s with a history of stroke and diabetes are at higher risk. The study's findings suggest that using age-specific ri...
