A large Danish registry study found that current use of oral menopausal hormone therapy was associated with increased venous thromboembolism risk, while transdermal therapy was not generally associated with higher thrombotic rates across regimens, doses, or durations.

A perimenopausal woman presenting with ST-segment elevation myocardial infarction was found to have both spontaneous coronary artery dissection and stress-induced cardiomyopathy, highlighting the diagnostic complexity and potential overlap of two uncommon causes of acute coronary syndrome in women.

Analysis of NHANES data suggests that adoption of the 2026 ACC/AHA dyslipidemia guidelines could make approximately 25 million additional US adults eligible to consider statin therapy, primarily through incorporation of PREVENT risk equations and expanded emphasis on long-term cardiovascular risk.

Targeted vitamin D supplementation successfully addressed widespread vitamin D insufficiency among post-myocardial infarction patients but did not significantly reduce major adverse cardiovascular events during more than four years of follow-up.

Adding coronary artery calcium scoring to PREVENT-ASCVD risk equations produced only modest improvements in 10-year ASCVD risk prediction among adults aged 45 to 79 years, with the greatest potential value observed in patients with borderline or intermediate estimated risk.
