Clinical Outcomes Following Optical Coherence Tomographic Versus Intravascular Ultrasound-Guided Percutaneous Coronary Intervention: A Meta-Analysis of Randomized Controlled Trials.

Background: Optical coherence tomography (OCT) and intravascular ultrasound (IVUS) are adjunctive intracoronary imaging modalities used to optimize coronary stent implantation. However, the impact of OCT versus IVUS on clinical outcomes and periprocedural complications is unclear.

Aims: To perform a meta-analysis of all vetted randomized controlled trials comparing OCT-guided versus IVUS-guided percutaneous coronary intervention.

Percutaneous Coronary Intervention in Men, Women, and Minorities With a Previous Coronary Artery Bypass Graft Surgery (from the Pooled PLATINUM Diversity and PROMUS Element Plus Registries).

There is limited data on new-generation stent outcomes in patients with previous coronary artery bypass graft (CABG) and the associated risk of gender and race/ethnicity is unclear. We investigated 1-year outcomes after platinum chromium everolimus-eluting stent implantation in a diverse population of men, women, and minorities with previous CABG pooled from the PLATINUM Diversity (NCT02240810) and PROMUS Element Plus (NCT01589978) registries. Our primary outcome was major adverse cardiac events (MACE), a composite of all-cause death, myocardial infarction (MI), and target vessel revascularization (TVR) at 1-year post percutaneous coronary intervention (PCI).

Coronary subclavian steal syndrome causing myocardial Infarction.

Coronary subclavian steal syndrome (CSSS) is a rare complication of the internal mammary artery (IMA) grafting in coronary artery bypass surgery. The technical definition is myocardial ischemia due to the reduced flow of blood, or flow reversal in the IMA graft. This in most cases results from hemodynamically significant proximal subclavian artery stenosis.

Impact of calcification on percutaneous coronary intervention: MACE-Trial 1-year results.

Objectives: The Multi-center Prospective Study to Evaluate Outcomes of Moderate to Severely Calcified Coronary Lesions (MACE-Trial) was designed to provide further insight on the impact of calcification on procedural and long-term percutaneous coronary intervention outcomes.

Background: Prior studies evaluating the impact of lesion calcification on percutaneous coronary intervention outcomes are limited by: retrospective nature, pooled data from multiple studies, or lack of specificity around calcification with only operator assessment and without core lab evaluation.

Methods: The MACE-Trial was a prospective, multicenter, observational clinical study that enrolled 350 subjects at 33 sites from September 2013 to September 2015.

Small-vessel PCI outcomes in men, women, and minorities following platinum chromium everolimus-eluting stents: Insights from the pooled PLATINUM Diversity and PROMUS Element Plus Post-Approval studies.

Objective: We evaluated 1-year outcomes after platinum chromium everolimus-eluting stents (PtCr-EES) in small versus non-small coronary arteries within a large, diverse sample of men, women, and minorities.

Background: There exists limited outcomes data on the use of second-generation drug-eluting stent to treat small diameter coronary arteries.

Methods: We pooled patients from the PLATINUM Diversity and PROMUS Element Plus stent registries.

The Left Distal Transradial Artery Access for Coronary Angiography and Intervention: A US Experience.

Background: The radial artery is the access of choice in many catheterization labs around the world due to its proven benefits over the femoral artery access. There has been growing interest in the left radial artery. We sought to evaluate the feasibility, safety and complication rates of the left distal radial artery (ldTRA) access for cardiac catheterization.

Cardiovascular Outcomes in Patients on Hemodialysis following Drug-Eluting versus Bare-Metal Coronary Stents.

Aim: This study sought to compare short- and long-term outcomes of drug-eluting stents (DESs) versus bare-metal stents (BMSs) implantation in patients with end-stage renal disease on hemodialysis (ESRD-HD) undergoing percutaneous coronary intervention (PCI).

Methods: Adult patients with ESRD-HD who underwent PCI at all nonfederal hospitals in Massachusetts between July 1, 2003, and September 30, 2007, were stratified based on the stent type placed at index hospitalization: DES or BMS. The primary outcome compared was a composite of all-cause death, myocardial infarction (MI), congestive heart failure (CHF), target vessel revascularization (TVR), and stroke at 30 days and one year.

Importance: There exist limited outcomes data for women and minorities after contemporary percutaneous coronary intervention (PCI).

Objective: To examine 1-year outcomes in women and minorities vs white men after PCI with everolimus-eluting stents.

Design, Settings, And Participants: The PLATINUM Diversity study was a single-arm study enrolling women and minorities.

Comparison of antithrombotic agents during urgent percutaneous coronary intervention following thrombolytic therapy: A retrospective cohort study.

Background: The optimal antithrombotic regimen for urgent percutaneous coronary interventions (PCI) following thrombolytic therapy for ST segment myocardial infarction (STEMI) is currently unknown.

Methods: We performed a retrospective analysis of all patients referred to our institution from January 2005 to July 2014 who underwent urgent PCI within 24 hr after receiving thrombolytic therapy. The patients were divided into three cohorts based on the anticoagulation strategy during PCI-bivalirudin, heparin alone or heparin plus Glycoprotein IIb/IIIa inhibitor (GPI).

The heavy LEGACY: Should weight management be part of every atrial fibrillation clinic?

As the global burden of atrial fibrillation (AF) and its attendant economic impact on the healthcare system surges, there is increasing interest in the secondary prevention of AF with various therapies. Of the several identified risk factors for AF, obesity is an important contributor that may be managed with intensive lifestyle modification. Prior studies have demonstrated the short-term and long-term benefits of weight loss in reduction of AF symptoms.

Plasma ProBNP Is Not a Specific Marker for Transient Myocardial Ischemia.

Background: Plasma proBNP levels are increased in patients with acute myocardial infarction. Previous studies have shown conflicting data on the effect of transient myocardial ischemia on plasma BNP levels. We designed the current study to examine plasma proBNP levels in patients with transient myocardial ischemia during a percutaneous coronary intervention (PCI).

Does knowledge of the cost of cardiovascular tests influence physician ordering patterns?

Introduction: The United States spends a higher percentage of its gross domestic product on health care than any other country. Previous efforts to curtail health care spending have had minimal impact. We hypothesized that informing physicians of the cost of expensive cardiovascular diagnostic tests would change their ordering behavior.

The impact of the distance from the interventional cardiologist's home to the hospital during off hours.

Objectives: The impact of the distance from the interventional cardiologist's home to the hospital and door to balloon time (DTBT) BACKGROUND: The importance of DTBT is highlighted by its inclusion as one of the core quality measures collected by the center for Medicare and Medicaid services and by the Joint commission on Accreditation of Healthcare organizations. We investigated the effect of time of day on the DTBT in patients having primary percutaneous coronary intervention (pPCI) and the impact of distance of the on call interventional cardiologist from the hospital on the DTBT and major adverse cardiac events (MACE) in patients undergoing pPCI during the off hours

Methods: Patients enrolled in the study presented with STEMI either in the field or to the emergency department (ED) and underwent pPCI from October 2007 to July 2009 RESULTS: Significant predictors of DTBT included a history of prior MI (P = 0.001), prior percutaneous coronary intervention (P = 0.

Reversible myocardial dysfunction following intraocular bevacizumab administration.

Heart failure has been reported as a rare side effect of bevacizumab, a chemotherapeutic agent, used in the treatment of breast cancer. However, reversible left ventricular systolic dysfunction with a pattern similar to stress-induced cardiomyopathy has not been reported. The etiopathogenesis of stress-induced cardiomyopathy is poorly understood.

ST segment elevation myocardial infarction as a presenting feature of thrombotic thrombocytopenic purpura.

Myocardial infarction with ST segment elevation (STE) on electrocardiography (ECG) is a common presentation in emergency rooms across the world. Myocardial injury and necrosis are infrequently the initial presentation in patients with thrombotic thrombocytopenic purpura (TTP). A 48-year-old woman presented with STE myocardial infarction from outside hospital for primary percutaneous coronary intervention.

A prospective multicenter registry of laser therapy for degenerated saphenous vein graft stenosis: the COronary graft Results following Atherectomy with Laser (CORAL) trial.

Purpose: The primary aim of this study was to prospectively evaluate the safety and efficacy of Excimer laser atherectomy as a primary treatment strategy in consecutively eligible patients presenting for percutaneous coronary intervention (PCI) of degenerated saphenous vein graft (SVG) lesions using a multicenter registry. Prior single-center experience suggested that laser atherectomy may decrease acute procedural complications during treatment of degenerated SVGs, including lesions not amenable to distal protection devices (DPDs).

Methods And Materials: The COronary graft Results following Atherectomy with Laser investigators enrolled 98 patients at 18 centers between June 23, 2003, and October 4, 2004, with greater than 50% stenosis of an SVG who presented for PCI due to angina pectoris or objective evidence of myocardial ischemia in a concordant myocardial distribution.

Postoperative atrial fibrillation is not associated with an increase risk of stroke or the type and number of grafts: a single-center retrospective analysis.

Background: Atrial fibrillation (AF) and atrial flutter are the 2 most common types of dysrhythmia in patients undergoing coronary artery bypass graft (CABG) surgery and are associated with increased morbidity and mortality. We sought to explore the association between the type and quantity of bypass grafts and cardiovascular outcomes in patients with postoperative AF (POAF).

Hypothesis: The type and quantity of bypass grafts is associated with POAF.

Acute renal artery occlusion: making the case for renal artery revascularization.

Atherosclerotic renal artery disease is a common disease entity that may be identified in patients with difficult-to-control hypertension and/or chronic kidney disease but is probably underdiagnosed. Current evidence from both observational and randomized studies offers mixed results regarding the support for renal artery revascularization. There is lack of equipoise with regard to the efficacy of renal artery revascularization among the interventional and renal communities, as well as disagreements on the appropriate endpoints to measure in clinical trials, which have led to selection bias confounding the scant available data.

Influence of low-dose aspirin (81 mg) on the incidence of definite stent thrombosis in patients receiving bare-metal and drug-eluting stents.

Background: Dual antiplatelet therapy with aspirin plus clopidogrel is the mainstay of therapy in patients undergoing percutaneous coronary intervention (PCI). However, the optimal dose of aspirin following PCI has not been established.

Hypothesis: There is no difference for definite stent thrombosis in patients taking low dose versus standard aspirin.
