Ischemic and Bleeding Events After First Major Bleeding Event in Patients Undergoing Coronary Stent Implantation
There is a scarcity of data on ischemic and bleeding events in patients who experienced major bleeding after percutaneous coronary intervention (PCI). Moreover, there also is a shortage of data on comparative outcomes between patients with and without interruption of an antithrombotic drug after major bleeding. We evaluated the incidence and prognostic impacts of ischemic (myocardial infarction or ischemic stroke) and bleeding (Bleeding Academic Research Consortium type 3 or 5) events after major bleeding in 12,691 consecutive patients who underwent first PCI in the Coronary Revascularization Demonstrating Outcome Study in...

Discriminative Ability of CHA2DS2-VASc and HAS-BLED Score in Whites and Nonwhites
The CHA2DS2-VASc and HAS-BLED scoring systems are used in patients with atrial fibrillation (AF) to estimate risk of stroke and bleeding, respectively. Both were developed in minimally diverse European populations and these scores have not yet been extensively studied in US whites and nonwhites. In a retrospective cohort study, we included patients with AF who received inpatient or outpatient care in a large integrated academic health system from 2011 to 2017. Cox proportional hazards were used to analyze associations between stroke and CHA2DS2-VASc score in AF patients not prescribed anticoagulation and between incident b...

A Simple and Portable Algorithm for Identifying Atrial Fibrillation in the Electronic Medical Record
Atrial fibrillation (AF) is common and increases stroke risk and mortality. Many knowledge gaps remain with respect to practice patterns and outcomes. Electronic medical records (EMR) may serve as powerful research tools if AF status can be properly ascertained. We sought to develop an algorithm for identifying individuals with and without AF in the EMR and compare it to previous methods. Using a hospital network EMR (n=5,737,846), we randomly selected 8,200 individuals seen at a large academic medical center in January 2014 to derive and validate seven AF classification schemas (4 case and 3 control) in order to construct...

Comparison of Hybrid Coronary Revascularization Versus Coronary Artery Bypass Grafting in Patients ≥65 Years With Multivessel Coronary Artery Disease
In this study, patients aged ≥65 years were included who underwent HCR at an academic center from October 2003 to September 2013. These patients were matched 1:4 to similar patients treated with coronary artery bypass grafting (CABG) using a propensity-score matching algorithm. Conditional logistic regression and Cox regression stratified on matched pairs were performed to evaluate the association between HCR and CABG, and 30-day major adverse cardiovascular and cerebrovascular events (a composite of mortality, myocardial infarction, and stroke), periprocedural complications, and 3-year all-cause mortality. Of 715 patien...

Performance of Bleeding Risk-Prediction Scores in Patients With Atrial Fibrillation Undergoing Percutaneous Coronary Intervention
In conclusion, the performance of ATRIA, HAS-BLED, mOBRI, and REACH scores in predicting bleeding complications in this high-risk patient subset was useless.

Comparison of In-Hospital Outcomes for Beta-Blocker Use Versus Non–Beta Blocker Use in Patients Presenting With Cocaine-Associated Chest Pain
In conclusion, no differences in outcomes were observed between patients treated versus not treated with β-blocker therapy in the setting of cocaine-related chest pain.

Impact of Diabetes Mellitus on Early and Midterm Outcomes After Transcatheter Aortic Valve Implantation (from a Multicenter Registry)
In conclusion, DM does not significantly affect rates of complications in patients who underwent TAVI. Insulin-treated DM, but not orally treated DM, is independently associated with death and myocardial infarction at midterm follow-up and should be included into future TAVI-dedicated scores.

Comparison of Procedural Complications With Versus Without Interventional Cardiology Fellows-in-Training During Contemporary Percutaneous Coronary Intervention

Comparison of Two Antiplatelet Therapy Strategies in Patients Undergoing Transcatheter Aortic Valve Implantation
The objective of this study was to compare 2 strategies of antiplatelet therapy in patients undergoing TAVI. A strategy using monoantiplatelet therapy (group A, n = 164) was prospectively compared with a strategy using dual antiplatelet therapy (group B, n = 128) in 292 consecutive patients undergoing TAVI. The primary end point was a combination of mortality, major stroke, life-threatening bleeding (LTB), myocardial infarction, and major vascular complications at 30 days. All adverse events were adjudicated according to the Valve Academic Research Consortium. The primary end point occurred in 22 patients (13.4%) in the...

Thrombocytopenia in Patients With Atrial Fibrillation on Oral Anticoagulation Undergoing Percutaneous Coronary Intervention
In conclusion, mild to moderate baseline thrombocytopenia does not seem to have a clinically significant effect on bleeding or thrombotic or thromboembolic complications after PCI in these frail patients receiving multiple antithrombotic drugs.

Effect of Dabigatran on Referrals to and Switching From Warfarin in Two Academic Anticoagulation Management Services
Dabigatran was expected to replace warfarin for stroke prevention in patients with nonvalvular atrial fibrillation (AF) who are warfarin naive, difficult to maintain in therapeutic range, or at risk of warfarin-related bleeding complications. We hypothesized that the number of patients with nonvalvular AF referred to Anticoagulation Management Services would decrease sharply and that most would switch from warfarin to dabigatran. We evaluated the number of patients with nonvalvular AF referred to 2 large services, Anticoagulation Management Service 1 and Anticoagulation Management Service 2, 12 months before and after mark...

Comparison of Procedural Success and Long-Term Outcomes of Stent Thrombosis in Coronary Bypass Grafts Versus Native Coronary Arteries
Percutaneous coronary intervention within bypass grafts accounts for a significant percentage of total interventions. Bypass graft interventions are associated with an increased risk for stent thrombosis (ST), a condition that leads to significant morbidity and mortality. Despite this, the procedural characteristics and long-term outcomes of patients with bypass-graft ST have not been reported. The aim of the present study was to evaluate the procedural success and long-term outcomes of patients presenting with ST of coronary bypass grafts. Clinical and procedural characteristics of 205 ST cases at 5 academic hospitals wer...
