The ESC guidelines now strongly recommend the radial approach over femoral access for coronary angiography and PCI in patients with acute coronary syndromes. The radial approach reduces vascular complications, major bleeding events, and all-cause mortality. Additionally, the guidelines suggest a tailored duration of dual antiplatelet t...
A recent study found that coagulation tests used to monitor internal bleeding in patients taking blood thinners like Xarelto and Eliquis may not be reliable. The tests, such as prothrombin time (PT), PTT, or INR, were found to be elevated in a minority of cases but appear unreliable to measure the risk of internal bleeding.

A new study finds that carbon monoxide can help accelerate the natural process of clearing heme, a toxic component of red blood cells, and reduce neuronal injury in mice with subarachnoid hemorrhage. The study suggests that low amounts of CO may be used to treat patients with ruptured cerebral aneurysms.
A systematic review of published evidence found that extended dual antiplatelet therapy (DAPT) decreases the risk for myocardial infarction but increases major bleeding events and may increase mortality. The authors suggest based on patient preferences after discussing benefits and harms.
Current users of menopausal hormone therapy are twice as likely to develop lower gastrointestinal bleeding and ischemic colitis compared to non-users. The study found a higher risk of bleeding in the lower GI tract due to fewer blood vessels supplying this area.
