Efficacy and safety of apixaban and warfarin in prevention of ischemic stroke: a systematic review and meta-analysis - PubMed
Source : https://pubmed.ncbi.nlm.nih.gov/40395880/
Apixaban has more advantages and a higher safety profile than warfarin, making it worthy of widespread use.
This meta-analysis of 11 studies (n=240,652) found apixaban and warfarin have similar efficacy for ischemic stroke prevention, but apixaban significantly reduces major bleeding, intracranial hemorrhage, and gastrointestinal bleeding—supporting its safer profile for anticoagulation in atrial fibrillation.

Patient Background:
A 39-year-old male presented with exertional dyspnea, orthopnea, and shortness of breath. He was an active smoker with a history of pulmonary edema 10 months prior. On admission, his blood pressure was 120/70 mmHg, and he was receiving bisoprolol, ramipril, and furosemide. Though family history was unspecified, aortic dilation prompted consideration of first-degree relative screening, as recommended in bicuspid valve disease.
Assessment & Diagnosis:
Transthoracic echocardiography revealed severe aortic regurgitation (grade 4+), a left ventricular end-diastolic diameter of 65 mm, and preserved ejection fraction of 56%. The ascending aorta measured 54 mm. Preoperative imaging suggested a bicuspid aortic valve; however, intraoperative inspection revealed a rare pentacuspid aortic valve with five variably sized cusps, some exhibiting partial fusion. The final diagnosis was severe aortic regurgitation and ascending aortic aneurysm due to a pentacuspid valve anomaly.
- Why is pentacuspid aortic valve important in the workup of severe AR?
- How does early surgical intervention influence long-term outcomes in such patients?
