A new study has found that women with low-density lipoprotein (LDL) cholesterol levels below 70 mg/dL may be at a higher risk of hemorrhagic stroke. The study also found that women with the lowest triglyceride levels had an increased risk of bleeding strokes compared to those with the highest triglyceride levels.
A study published in EClinicalMedicine found that preterm babies born without the haptoglobin protein have a higher risk of brain bleeding, cerebral palsy, and death. The absence of the protein may serve as a potential biomarker for increased monitoring or preventive interventions.
Researchers found that ticagrelor has comparable efficacy to clopidogrel in patients treated with clot busters for a heart attack. The trial also showed that ticagrelor is safe for use in this patient population, with low rates of major bleeding.
Patients who stopped taking aspirin and continued clopidogrel fared significantly better after one year, with a reduced risk of bleeding and no increase in clot-related events. The study suggests that stopping DAPT after one month may be a good option for patients after drug-eluting stent implantation.

The HeartMate 3 left ventricular assist device (LVAD) significantly reduces strokes, pump-related blood clots, and bleeding episodes compared to the older HeartMate II. This trial enrolled 1,028 patients with advanced heart failure, showing a 40% reduction in risk favoring the HeartMate 3.
Patients who stopped taking aspirin three months after receiving a stent had a significantly lower rate of bleeding and no higher rate of death from any cause, heart attack, or stroke compared to those following standard therapy. The study's results balance ischemic and bleeding risks in patients undergoing PCI.

Patients on SSRIs are 40% more likely to develop severe GI bleeding when taking NSAIDs, according to a review in the Journal of the American Osteopathic Association. Physicians should educate patients on recognizing symptoms and monitor for bleeding risks during SSRI therapy.
A meta-analysis of 13 clinical trials involving over 164,000 participants found that aspirin use was associated with a lower risk of cardiovascular events, including death, heart attack, and stroke. However, it also increased the risk of major bleeding in people without pre-existing cardiovascular disease.

Patients with cardiovascular disease who experience major internal bleeding are more likely to be diagnosed with cancer, particularly gastrointestinal and genitourinary tract cancers. The study, which involved over 27,000 patients in 33 countries, suggests that bleeding may serve as an early warning sign for occult cancers.
