INTRODUCTION: Thienopyridines are a class of antiplatelet drugs widely used in cardiovascular disease prevention and treatment. A recent concern has come to light regarding the safety of thienopyridines because of the possible risk of malignancy. We therefore performed a systematic review and meta-analysis to evaluate the association between thienopyridine exposure and malignancy. METHODS: We searched the MEDLINE and EMBASE databases in March 2016 for studies that evaluated incident cancer and cancer mortality with and without exposure to thienopyridines...

OBJECTIVES: To assess the mortality in patients with diabetes mellitus (DM) following percutaneous coronary intervention (PCI) according to their insulin requirement and PCI setting (elective, urgent, and emergency). BACKGROUND: DM is a major risk factor to develop coronary artery disease (CAD). It is unclear if meticulous glycemic control and aggressive risk factor management in patients with DM has improved outcomes following PCI. METHODS: Retrospective analysis of prospectively collected data on 9,224 patients treated with PCI at a regional tertiary center between 2008 and 2011...

Myocardial and vascular endothelial tissues have receptors for thyroid hormones and are sensitive to changes in the concentrations of circulating thyroid hormones. The importance of thyroid hormones in maintaining cardiovascular homeostasis can be deduced from clinical and experimental data showing that even subtle changes in thyroid hormone concentrations - such as those observed in subclinical hypothyroidism or hyperthyroidism, and low triiodothyronine syndrome - adversely influence the cardiovascular system...

BACKGROUND: Coronary artery bypass grafting (CABG) is the standard treatment for revascularisation in patients with left main coronary artery disease, but use of percutaneous coronary intervention (PCI) for this indication is increasing. We aimed to compare PCI and CABG for treatment of left main coronary artery disease. METHODS: In this prospective, randomised, open-label, non-inferiority trial, patients with left main coronary artery disease were enrolled in 36 centres in northern Europe and randomised 1:1 to treatment with PCI or CABG...

Transcatheter aortic valve replacement (TAVR) is conventionally performed under general anesthesia (GA) allowing intraoperative transoesophageal echocardiogram imaging. We present our experience in patients having the procedure under local anesthesia (LA), who were subsequently transferred to a low dependency unit postprocedure, to assess safety and length of hospital stay. We retrospectively assessed all the transfemoral TAVR procedures conducted at our center from January 03, 2011. Of 216 patients, 145 had the procedure under GA and 71 under LA...

OBJECTIVES: This study sought to determine the effect of adding computed tomography-derived fractional flow reserve (FFRCT) data to computed tomography angiographic (CTA) data alone for assessment of lesion severity and patient management in 200 patients with chest pain. BACKGROUND: Invasive and noninvasive tests used in the assessment of patients with angina all have disadvantages. The ideal screening test for patients presenting for the first time with chest pain would describe both coronary anatomy and the presence of ischemia and would be readily accessible, low cost, and noninvasive...

AIMS: Non-ST-elevation acute coronary syndrome (NSTE-ACS) is present in about 60-70% of patients admitted with acute coronary syndromes in clinical practice. This study provides a 'real-life' overview of NSTE-ACS patient characteristics, dual antiplatelet therapy clinical practice, and outcomes at both the time of discharge from hospital and up to 1-year post-discharge. METHODS AND RESULTS: A total of 10 registries (documenting 84 054 NSTE-ACS patients) provided data in a systematic manner on patient characteristics and outcomes for NSTE-ACS in general, and 6 of these (with 52 173 NSTE-ACS patients) also provided more specific data according to P2Y12 receptor inhibitor used...

AIMS: Among acute coronary syndromes (ACS), ST-segment elevation myocardial infarction (STEMI) has the most severe early clinical course. We aimed to describe the effectiveness and safety of P2Y12 receptor inhibitors in patients with STEMI based on the data from contemporary European ACS registries. METHODS AND RESULTS: Twelve registries provided data in a systematic manner on outcomes in STEMI patients overall, and seven of these also provided data for P2Y12 receptor inhibitor-based dual antiplatelet therapy...

Anemia is common in patients undergoing percutaneous coronary intervention (PCI), and current guidelines fail to offer recommendations for its management. This review aims to examine the relation between baseline anemia and mortality, major adverse cardiovascular events (MACE), and major bleeding in patients undergoing PCI. We searched MEDLINE and EMBASE for studies that evaluated mortality and adverse outcomes in anemic and nonanemic patients who underwent PCI. Data were collected on study design, participant characteristics, definition of anemia, follow-up, and adverse outcomes...

BACKGROUND AND PURPOSE: Stroke after percutaneous coronary intervention (PCI) is a serious complication, but its determinants and outcomes after PCI in different clinical settings are poorly documented. METHODS: The British Cardiovascular Intervention Society (BCIS) database was used to study 560 439 patients who underwent PCI in England and Wales between 2006 and 2013. We examined procedural-type specific determinants of ischemic and hemorrhagic stroke and the likelihood of subsequent 30-day mortality and in-hospital major adverse cardiovascular events (a composite of in-hospital mortality, myocardial infarction or reinfarction, and repeat revascularization)...

BACKGROUND: There are limited data on outcomes of patients with previous coronary artery bypass grafting (CABG) presenting with ST-segment-elevation myocardial infarction (STEMI) and undergoing primary percutaneous coronary intervention (PPCI). We report outcomes in patients with STEMI undergoing PPCI with or without previous CABG surgery in a large real-world, all-comer population. METHODS AND RESULTS: Clinical, demographic, procedural, and outcomes data were collected for all patients undergoing PPCI in England and Wales from January 2007 to December 2012...

BACKGROUND: The transradial access (TRA) site has become the default access site for percutaneous coronary intervention in the United Kingdom, with randomized trials and national registry data showing reductions in mortality associated with TRA use. This study evaluates regional changes in access site practice in England and Wales over time, examines whether changes in access site practice have been uniform nationally and across different patient subgroups, and provides national estimates for the potential number of lives saved or lost associated with regional differences in access site practice...

BACKGROUND: Lymphocytes contribute to ischemia/reperfusion (I/R) injury in several organ systems, but their relevance in ST elevation myocardial infarction (STEMI) is unknown. Our goal was to characterize lymphocyte dynamics in individuals after primary percutaneous coronary intervention (PPCI), assess the prognostic relevance of these cells, and explore mechanisms of lymphocyte-associated injury. METHODS: Lymphocyte counts were retrospectively analyzed in 1,377 STEMI patients, and the prognostic relevance of post-PPCI lymphopenia was assessed by Cox proportional hazards regression...

BACKGROUND: Gender is a strong predictor of periprocedural major bleeding complications after percutaneous coronary intervention (PCI). The access site represents an important site of such bleeding complications, which has driven adoption of the transradial access (TRA) use during PCI, although female gender is an independent predictor of transradial PCI failure. This study sought to define gender differences in access site practice and study associations between access site choice and clinical outcomes for PCI over a 6-year period, through the analysis of the British Cardiovascular Intervention Society observational database...

Neurocutaneous melanosis is a rare neuroectodermal dysplasia with a grave prognosis. It is actually a disorder of neuronal migration at the time of the embryogenesis hence classified as a neurocristopathy. The patients are initially identified by the skin manifestations of the disease in the form of melanocytic naevus which can be hairy or non-hairy. These patients may or may not present with neurological symptoms but often show CNS abnormalities especially on MRI of the brain and the spine. A lot has been described about the disease since the first case described by Rokitansky in 1861, but every time a new CNS pathology is being added to the long list of currently documented pathologies...
