Radial Artery Access Complications: Prevention, Diagnosis and Management.

The transradial approach for cardiac catheterization, coronary angiography, and percutaneous intervention is associated with a lower risk of access site-related complications compared to the transfemoral approach. However, with increasing utilization of transradial access for not only coronary procedures but also peripheral vascular procedures, healthcare personnel are more likely to encounter radial access site complications, which can be associated with morbidity and mortality. There is significant heterogeneity in the reporting of incidence, manifestations, and management of radial access site complications, at least partly due to vague presentation and under-diagnosis.

Improving outcomes of percutaneous coronary interventions in patients with stable ischemic heart disease.

Percutaneous coronary intervention (PCI) is a common cardiac procedure and there have been significant advances in the technologies over past decades that have improved the safety of these procedures. Various clinical trials and meta-analyses have shown that PCIs are associated with improved outcomes, especially among patients with acute coronary syndromes. However, the clinical benefit of PCIs among patients with stable ischemic heart disease (SIHD) other than improvement in anginal symptoms is less well established.

Outcomes in Patients Undergoing Primary Percutaneous Coronary Intervention for ST-Segment Elevation Myocardial Infarction Via Radial Access Anticoagulated With Bivalirudin Versus Heparin: A Report From the National Cardiovascular Data Registry.

Objectives: The aim of this study was to compare bivalirudin with heparin as anticoagulant agents in patients with ST-segment elevation myocardial infarction treated with radial primary percutaneous coronary intervention (PCI).

Background: Recent studies in which PCI was performed predominantly via radial access did not show bivalirudin to be superior to heparin.

Methods: Outcomes were compared in patients with STEMI included in the National Cardiovascular Data Registry CathPCI database from 2009 to 2015 who underwent primary PCI via radial access and who were anticoagulated with bivalirudin or heparin.

Guideline-Appropriate Care and In-Hospital Outcomes in Patients With Heart Failure in Teaching and Nonteaching Hospitals: Findings From Get With The Guidelines-Heart Failure.

Background: Despite increasing awareness regarding evidence-based guidelines, considerable gaps exist for heart failure (HF) quality of care at teaching hospitals (TH) and nonteaching hospitals (NTH). We analyzed data from Get With The Guidelines (GWTG)-HF to compare the rates and trends of guideline-recommended care at TH and NTH for patients with HF.

Method And Results: Baseline patient characteristics, performance measures, and in-hospital outcomes were compared between 197 187 HF patients admitted to TH and 106 924 patients admitted to NTH between 2005 and 2014.

Pulmonary Hypertension After Heart Transplantation in Patients Bridged with the Total Artificial Heart.

Pulmonary hypertension (PH) among heart transplant recipients is associated with an increased risk of mortality. Pulmonary hemodynamics improves after left ventricular assist device (LVAD) implantation; however, the impact of PH before total artificial heart (TAH) implantation on posttransplant hemodynamics and survival is unknown. This is a single center retrospective study aimed to evaluate the impact of TAH implantation on posttransplant hemodynamics and mortality in two groups stratified according to severity of PH: high (≥3 Woods units [WU]) and low (<3 WU) baseline pulmonary vascular resistance (PVR).

Vascular responses to drug-eluting and bare metal stents in diabetic/hypercholesterolemic and nonatherosclerotic porcine coronary arteries.

Background: Animal models used to gain insight into the vascular response to drug-eluting stents are generally juvenile and nonatherosclerotic, whereas stents are placed in patients with complex atherosclerosis and comorbidities. Hence, models reflecting these complexities are needed to help elucidate the vascular effects of drug-eluting stents. We compared the vascular responses with bare metal stent (BMS) and paclitaxel-eluting stent (PES) implantation in a diabetic/hypercholesterolemic (DM/HC) porcine model of advanced coronary atherosclerosis with the standard juvenile porcine model.
