Muhammad Aqib Faizan: The Role of Novel Anticoagulants Factor XI/XIa Inhibitors in the Atrial Fibrillation Population

Muhammad Aqib Faizan, Clinical Intern at District Headquarter Hospital, MTI, DIKhan, shared a post on LinkedIn about a recent article he and his colleagues co-authored, adding:

”New study

I had the privilege of leading this study regarding the role of novel anticoagulants FactorXI/XIa inhibitors in atrial fibrillation population (high-thromboembolic-risk patients (mean CHA2DS2-VASc scores 3.9-5.0).

The findings offer a compelling trade-off.

  • Significantly lower risk of bleeding across all doses
  • Fourfold rise in ischemic stroke
  • No significant difference in cardiovascular death, all-cause mortality, or major adverse events indicates general tolerance and neutrality in survival outcomes.

This profile may offer a lifeline for high-risk patients-those in whom bleeding concerns limit traditional anticoagulation.
But the fourfold increase in ischemic stroke is a critical signal.

Proud of what this team accomplished. Huge thanks to Tooba Rehman, Zeyad Kholeif, Fatima Saeed, Jibran Ikram, Alina Tanvir, Carlos Alberto E., Saad Ahmed Waqas, and our mentor, Luis Cerna, whose insights made this happen.”
