The Utility Of Has-Bled Score In Predicting The Bleeding Risk Of Atrial Fibrillation Patients Undergoing Percutaneous Coronary Intervention Receiving Anticoagulation And Dual Anti-Platelet Therapy: A Single Center Retrospective Cohort Study, Luk Yin Cheung Adrian, Chan Chi Lin Jaclyn

Journal of the Hong Kong College of Cardiology

Background The Hypertension, Abnormal renal/liver function, Stroke, Bleeding history or predisposition, Labile international normalized ratio, Elderly and Drugs/alcohol (HAS-BLED) score is a validated bleeding risk prediction tool in patients with atrial fibrillation taking oral anticoagulation. Its predictive value in patients with atrial fibrillation undergoing percutaneous coronary intervention receiving combination of anticoagulation and antiplatelet therapy is unknown. This retrospective cohort study sought to validate the accuracy of HAS-BLED score in predicting the bleeding risk in patients with atrial fibrillation who underwent percutaneous coronary intervention receiving both anticoagulation and dual antiplatelet therapy. Method We calculated HAS-BLED score in 186 patients with AF …

Stent Thrombosis: Regional Prevalence, Risk Factors, And Outcomes, Andrew M. Ayers, Chi C. Cho, Robyn Shearer, M. Fuad Jan, Anjan Gupta

Journal of Patient-Centered Research and Reviews

Background: Stent thrombosis is an infrequent but catastrophic complication of percutaneous coronary intervention (PCI). Many studies usually involve few stent thrombosis patients, generally less than 60, given its prevalence. While dual antiplatelet therapy has decreased stent thrombosis significantly in the general population, there are still patients who present with occurrence and recurrence of stent thrombosis.

Purpose: We sought to define the prevalence of site-specific stent thrombosis in a larger cohort of patients by specific coronary territories and determine if this had an effect on cardiovascular outcomes. In addition we sought to elucidate the role of previous coronary artery bypass grafting …

Clinical Outcomes Of Unprotected Left Main Coronary Artery Stenting In Nonsurgical Patients: A Single-Center Experience, John-Paul Pham, Abdelazim Hashim, Naoyo Mori, Mohamed Taha, Mohamed Djelmami-Hani, Joaquin Solis, Suhail Allaqaband, Tanvir Bajwa, Anjan Gupta

Journal of Patient-Centered Research and Reviews

Purpose: Coronary artery bypass graft is the standard treatment for unprotected left main disease; however, some patients are poor surgical candidates due to comorbidities. We assessed the safety and clinical outcome of elective, unprotected left main coronary artery stenting in nonsurgical patients.

Methods: Between October 2004 and June 2006, 50 consecutive patients underwent elective, unprotected left main coronary artery stenting at our institution. Patients were followed for a median of 16 and 96 months and clinical outcomes monitored.

Results: Median logistic euroSCORE was 28.6 (interquartile range: 14.6-43.4). Median baseline left ventricular ejection fraction (LVEF) was 50%. Procedural success rate was …
