BACKGROUND: Postconditioning can affect the infarct size in acute myocardial infarction (AMI). However, few studies show an effect of different postconditioning cycles on AMI aged patients. This study sought to assess the effect of different postconditioning cycles on prognosis in aged patients with AMI who underwent primary percutaneous coronary intervention (PCI). METHODS: 74 aged patients were randomly assigned to three groups. Control group; PC-1 group accepted postconditioning 4 cycles of 30 s inflation and 30 s deflation; PC-2 group accepted postconditioning 4 cycles of 60 s...

BACKGROUND: Circulating endothelial cells (CECs) are widely reported as a promising biomarker of endothelial damage/dysfunction in coronary artery disease (CAD). The two popular methods of CEC quantification include the use of immunomagnetic beads separation (IB) and flow cytometry analysis (FC); however, they suffer from two main shortcomings that affect their diagnostic and prognostic responses: non-specific bindings of magnetic beads to non-target cells and a high degree of variability in rare cell identification, respectively...

OBJECTIVES: We sought to analyze the percutaneous coronary intervention (PCI) outcomes of very elderly patients (V. Eld. group, age >80 years) and compare their outcomes to a less elderly cohort (Eld. group, age 75-80 years) traditionally reported in the literature. BACKGROUND: Limited data exist on peri-procedural and long-term outcomes following PCI in the V. Eld. (age >80 years), with under-representation of this cohort in randomized controlled trials. These patients present with advanced complex coronary disease and multiple comorbidities...

Thrombus exerts a major impact on the performance and outcome of primary and rescue interventions in acute ST-elevation myocardial infarction. Although the optimal treatment of thrombotic lesions is still controversial, thrombus aspiration provides an effective method to achieve successful reperfusion during primary angioplasty. We compared clinical and angiographic outcomes in 286 patients with acute ST-elevation myocardial infarction undergoing primary percutaneous transluminal coronary angioplasty (PTCA) and thrombus aspiration with those who underwent conventional PTCA without thrombus aspiration...

BACKGROUND: Digoxin is widely used in patients with atrial fibrillation despite the lack of randomized controlled trials. Observational studies report conflicting results regarding its association with mortality, perhaps because of residual confounding by the presence of heart failure (HF). METHODS AND RESULTS: In the ENGAGE AF-TIMI 48 (Effective Anticoagulation With Factor Xa Next Generation in Atrial Fibrillation-Thrombolysis in Myocardial Infarction 48) trial, clinical outcomes of patients with atrial fibrillation with and without HF were examined by baseline digoxin use during a median follow-up of 2...

OBJECTIVES: We explored the predictors and outcome of poor, versus good, initial TIMI flow in patients with acute coronary syndrome (ACS). DESIGN: We performed post-hoc analysis of a randomized trial of patients presenting with ACS who received 2 comparative stents. Poor initial TIMI flow was defined as baseline TIMI flow grade 0/1 at the initial coronary angiography. The primary endpoint was major adverse cardiac events (MACE): a composite of cardiac death, non-fatal myocardial infarction or ischemia-driven target lesion revascularization...

Spontaneous coronary artery dissection or SCAD is a rare and challenging disease that is increasingly diagnosed. It is characterized by a non-traumatic, non-iatrogenic separation of the coronary artery wall and occurs predominantly in young and middle-aged women without traditional cardiovascular risk factors. SCAD is often associated with predisposing conditions such as the peripartum period, systemic inflammatory disease and heritable connective tissue disease. More recently, independent investigators have demonstrated an important association with fibromuscular dysplasia...

Background -Patients with minor acute ischemic stroke (AIS) or transient ischemic attack (TIA) are at high risk for subsequent stroke, and more potent antiplatelet therapy in the acute setting is needed. However, the potential benefit of more intense antiplatelet therapy must be assessed in relation to the risk for major bleeding. The SOCRATES trial was the first trial with ticagrelor in patients with AIS or TIA, in which the efficacy and safety of ticagrelor were compared with aspirin. The main safety objective was assessment of PLATO-defined major bleeds on treatment, with special focus on intracranial hemorrhage (ICrH)...

The objective of this study was to establish the prevalence, contamination level, and public health significance of Giardia duodenalis and Cryptosporidium spp. in the primary rivers of western Romania. A total of 53 sampling points in the 24 most important western Romanian rivers in four counties (Arad, Bihor, Caraș-Severin, and Timiș) were investigated from March to September 2016. Surface water samples were collected by microfiber filtration. Cryptosporidium and Giardia (oo)cysts were isolated using immunomagnetic separation (IMS) according to the USEPA 1623 method and, after staining with fluorescently labeled (FITC) monoclonal antibodies, were identified and counted under a microscope...

BACKGROUND: This study investigated whether body mass index (BMI) was a risk factor predictive of 30-day prognostic outcome in Asians with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). MATERIAL AND METHODS: Data regarding the impact of BMI on the prognostic outcome in Asian populations after acute STEMI is scarce. A number of 925 STEMI patients were divided into three groups according to the BMI: normal weight (<25 kg/m(2)), overweight (≥25...

BACKGROUND: It has been reported that coronary slow flow (CSF) is associated with acute myocardial infarction, ventricular tachycardia, ventricular fibrillation, and even sudden cardiac death. Although studies concerning the etiopathogenesis of CSF are scarce, diffuse atherosclerosis and endothelial dysfunction are thought to play important roles. It has been suggested that a high plasma thrombomodulin (TM) level seems to play an important role in the pathogenesis of atherosclerosis and endothelial dysfunction...

BACKGROUND: Primary percutaneous coronary intervention (PCI) is the current standard of care for acute ST elevation myocardial infarction (STEMI). Most of the data on primary PCI in acute STEMI is from western countries. We studied the outcomes of primary PCI for acute STEMI at a tertiary care center in North India. METHODS: Consecutive patients undergoing primary PCI for STEMI were prospectively studied during the period from February 2103 to May 2015. The outcomes assessed were all cause in hospital mortality, factors associated with mortality, major adverse cardiac and cerebrovascular event rate (composite of all cause in hospital mortality, non-fatal re infarction and stroke) and procedural complications...

BACKGROUND: Novel anticoagulants, such as factor Xa inhibitors, have entered clinical practice as alternatives to warfarin for the prevention of stroke and systemic embolic event (SEE) in patients with atrial fibrillation (AF). It is not known whether edoxaban, the fourth-to-market factor Xa inhibitor approved for this indication, will be cost-effective in Taiwan, where the cost of warfarin monitoring is prohibitive. METHODS: A Markov model projecting lifetime results of edoxaban 60 mg/30 mg dose-reduced versus warfarin in patients with nonvalvular AF, based on the ENGAGE AF - TIMI 48 trial, found edoxaban to be of high value relative to warfarin, from the perspective of the US health care system...

Fractional flow reserve (FFR) guided percutaneous coronary intervention (PCI) is associated with favourable outcome compared with revascularization based on angiographic stenosis severity alone. The feasibility of the new image-based quantitative flow ratio (QFR) assessed from 3D quantitative coronary angiography (QCA) and thrombolysis in myocardial infarction (TIMI) frame count using three different flow models has been reported recently. The aim of the current study was to assess the accuracy, and in particular, the reproducibility of these three QFR techniques when compared with invasive FFR...

Dual anti-platelet therapy is prescribed in the setting of coronary heart disease for the prevention of stent thrombosis and acute thrombotic events. The optimal duration of dual anti-platelet therapy is still under debate as numerous trials have shown non-inferiority of a strategy of early cessation of one of the agents as compared to the standard practice whereas two larger trials have demonstrated benefit of prolonging dual anti-platelet therapy.

Primary percutaneous coronary intervention (pPCI) is associated with improved prognosis in patients with ST-segment elevation myocardial infarction (STEMI). However, no-reflow phenomenon limits the benefit of revascularization and predicts adverse outcomes. The specific mechanism for its occurrence is still not entirely clear, and it is believed at present that platelet activation and inflammation play a pivotal role in developing no-reflow. Both increased mean platelet volume (MPV), which is a platelet activation marker, and lymphopenia, which is an inflammation marker, have been linked to adverse events and poor prognosis after STEMI...

AIMS: Early infarct-related artery patency has been associated with improved outcomes in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention. However, it is unknown whether this relationship persists in contemporary practice with pre-hospital initiation of treatment, use of novel P2Y12 inhibitors and frequent use of drug-eluting stents. The purpose of the study was to determine the impact of early infarct-related artery patency on outcomes in the contemporary EUROMAX trial...
