Many studies have shown gender differences in the progress of acute coronary syndromes (ACS). These differences include, amongst others, processes involved in hemostasis and inflammation, and in the present study we put forward the hypothesis that these are the primary cause of other differences. The study included 66 ACS patients (27 women and 39 men) aged 43 - 83 years, 23 with non-ST-elevation myocardial infarction (NSTEMI) and 43 with ST-elevation myocardial infarction (STEMI). Blood samples were taken on day 3 (NSTEMI) or day 5 (STEMI) after hospitalization, and fibrinogen, D-dimers, von Willebrand factor, C-reactive protein and interleukin-6 levels measured...

Our goal was to assess adherence to American College of Cardiology/American Heart Association guideline-based medical therapy in patients admitted with type I non-ST elevation myocardial infarction (NSTEMI) and to determine factors associated with medication administration delay. We performed a retrospective analysis using data from the Acute Coronary Treatment and Intervention Outcomes Network (ACTION) Registry. Baseline patient demographics, 12-lead electrocardiogram (ECG) findings, laboratory values, medications administered and the time they were administered, and in-hospital clinical outcomes were collected...

Circulating microRNAs (miRNAs) hold great potential as novel diagnostic markers for acute coronary syndrome (ACS). This study sought to identify plasma miRNAs that are differentially expressed in young ACS patients (mean age of 38.5 ± 4.3 years) and evaluate their diagnostic potentials. Small RNA sequencing (sRNA-seq) was used to profile plasma miRNAs. Discriminatory power of the miRNAs was determined using receiver operating characteristic (ROC) analysis. Thirteen up-regulated and 16 down-regulated miRNAs were identified in young ACS patients...

Anomalies of the coronary arteries are reported in 1-2% of patients among diagnostic angiogram. Ectopic origin of right coronary artery (RCA) from opposite sinus is one of the most common and they are mainly benign, but at times may be malignant. We report a case of a 69-year-old male who underwent early invasive percutaneous coronary intervention for non-ST-segment elevation myocardial infarction (NSTEMI) where RCA arising from left sinus at the root of left main artery was culprit and various technical challenges were encountered while intervening in form of cannulation to tracking of hardwares...

BACKGROUND: It is known that women generally have worse mortality outcomes than men with regards to ST-segment elevation myocardial infarction. However, less is known about contemporary gender differences in non-STEMI acute coronary syndrome, particularly those presenting to emergency departments within a regionalized system of care with standardized protocols. METHODS: Retrospective registry data from 2010 to 2016 were examined from the North Texas Mission: Lifeline system of care, representing 33 hospitals around the Dallas Texas metropolitan area...

BACKGROUND: Physical examination of jugular venous pressure is used to estimate right atrial (RA) pressure and infer left-sided filling pressure to assist volume management. Previous studies in advanced heart failure patients showed about 75% concordance between RA and pulmonary capillary wedge (PCW) pressures. We sought to determine the relationship between mean RA and mean PCW pressure and assess the clinical significance in a broad population of patients undergoing invasive right heart catheterization (RHC)...

BACKGROUND: Patients with acute coronary syndrome (ACS) due to unprotected culprit left main coronary artery disease (LMCAD) treated with percutaneous coronary intervention (PCI) are rare, high-risk, and not represented in trials. Data regarding long term outcome after PCI are limited. METHODS: Between January 2000 and December 2014, there were 8,794 patients hospitalized with unstable angina/non-ST elevation myocardial infarction (UA/NSTEMI) or ST-elevation myocardial infarction (STEMI) treated with PCI at our institution; of these, 83 (0...

Objective: Perioperative myocardial infarction remains a severe complication in non-cardiac surgery and is one of the major causes of death. Cardiac troponin (cTn) I elevation is associated with short-term and long-term mortality. The aim of the study was to assess the proportion rate of cTnI elevation and its clinical characteristics among patients admitted for orthopaedic surgery with or without cardiovascular events. Methods: This is a retrospective study including 27 744 patients aged 50 years or older who admitted for orthopaedic surgery from 2009-2015 in Beijing Jishuitan Hospital...

AIMS: Long-term comparisons between Drug-eluting stent and bare metal stent are not well-studied. The aim of this study was to compare two stents that were previously frequently used in regard to long-term risk of restenosis and stent thrombosis (ST). METHODS AND RESULTS: We used data from the SCAAR registry. Consecutive procedures performed between 2004 and 2014 for stable angina, UA/NSTEMI and STEMI were included. We compared two different stents: Cordis Cypher Select (C-CS), and Boston Scientific Liberte (BS-L), modeling data with multilevel Cox proportional-hazards regression...

Severe aortic stenosis (AS) is considered a contraindication to the use of mechanical circulatory support (MCS) devices, including the Impella heart pump (Abiomed, Aachen, Germany). We describe a case in which a 72-year-old female with severe AS and peripheral vascular disease (PVD) presented with retractable ischemia in the setting of a non-ST elevation myocardial infarction (NSTEMI). Using a coordinated multidisciplinary approach, our case is the first to combine iliac angioplasty, balloon aortic valvuloplasty (BAV), and the insertion of an Impella CP device in the setting of severe AS to facilitate successful coronary artery revascularization in a non-surgical patient...

Patients with ST segment elevation myocardial infarction (STEMI) and non-ST segment elevation myocardial infarction (NSTEMI) experience cardiogenic shock in about 6-10% of cases during the hospital treatment. In recent years, the incidence seems to be decreasing due to invasive diagnostics and therapy after myocardial infarction. Early diagnosis is important to initiate immediate revascularization using percutaneous coronary intervention (PCI) with stent implantation as part of cardiogenic shock treatment. Thus, a significant improvement in survival can be achieved...

INTRODUCTION: The classical pathophysiological process underlying acute coronary syndromes has been considered to be plaque rup-ture followed by platelet activation and aggregation and subsequent thrombus formation leading to myocardial ischemia and infarction. A substantial number of patients with acute coronary syndromes appear to have normal or near normal (<50% stenosis) coronary arteries on angiography. Recently, this clinical entity has been coined MINOCA (Myocardial Infarction with Non-Obstructive Coronary Arteries)...

BACKGROUND: Reduced preprocedural thrombolysis in myocardial infarction (TIMI) flow in patients with ST-segment elevation myocardial infarction (STEMI) is known to be associated with increased mortality. However, clinical implications of reduced preprocedural TIMI flow in patients with non-ST-segment elevation myocardial infarction (NSTEMI) have not been fully elucidated as yet. The aim of the present study was to compare the clinical influence of reduced preprocedural TIMI flows between patients with STEMI and NSTEMI undergoing percutaneous coronary intervention (PCI)...

Previous studies compared clinical outcomes of early versus delayed invasive strategy in patients with non-ST-elevation acute coronary syndrome up to 1-year follow-up, but long-term data remain scarce. Our aim was to evaluate the long-term effects of immediate invasive intervention in patients with Non-ST-Segment Elevation Myocardial Infarction (NSTEMI). The Randomized Study of Immediate Versus Delayed Invasive Intervention in Patients With Non-ST-Segment Elevation Myocardial Infarction (RIDDLE-NSTEMI) was a randomized, investigator-initiated, parallel-group trial that assigned 323 patients with NSTEMI (1:1) to either immediate (median time to intervention 1...

Patients with acute myocardial infarctions (AMIs) present as persistent ST-elevation myocardial infarction (STEMI) or as non-ST-segment elevation myocardial infarction (NSTEMI). In some patients with STEMI, ST elevations are transient and resolve before coronary intervention (transient ST-elevation myocardial infarction [TSTEMI]). We analyzed our registry comprising all consecutive patients with AMI admitted during 2009 to 2014, and compared the characteristics, management, and outcome of patients with TSTEMI with those of patients with STEMI and NSTEMI...
