OBJECTIVE: The extent of severity and complexity of coronary artery disease (CAD) in patients presenting with ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI) and possible correlations between serum 25-hydroxyvitamin D (25(OH)D) have not yet been adequately studied. We evaluated the relationship between 25(OH)D levels and the burden of CAD as assessed by the SYNTAX score (SXscore) in patients with acute coronary syndrome (ACS) including STEMI and NSTEMI. METHODS: After exclusion, a total of 113 patients who were admitted to our hospital due to ACS and who were referred for undergoing coronary angiography were prospectively included...

OBJECTIVE: The presence of chronic total occlusion (CTO) in noninfarct-related artery (non-IRA) is an independent predictor of mortality in acute myocardial infarction (AMI). We investigated whether red cell distribution width (RDW) levels are associated with presence of non-IRA-CTO in AMI (ST-elevation myocardial infarction [STEMI] and non-STEMI). PATIENTS AND METHODS: Patients (n = 858) were categorized into three groups: single vessel disease, multivessel disease (MVD) without CTO and MVD with CTO...

BACKGROUND: Oxygen (O2) is widely used in people with acute myocardial infarction (AMI). Previous systematic reviews concluded that there was insufficient evidence to know whether oxygen reduced, increased or had no effect on heart ischaemia or infarct size. Our first Cochrane review in 2010 also concluded there was insufficient evidence to know whether oxygen should be used. Since 2010, the lack of evidence to support this widely used intervention has attracted considerable attention, prompting further trials of oxygen therapy in myocardial infarction patients...

BACKGROUND: High-density lipoproteins (HDLs) protect against the development of atherosclerotic cardiovascular disease. HDL function represents an emerging concept in cardiovascular research. OBJECTIVE: This study investigated the association between HDL functionality and acute myocardial infarction (MI) independent of HDL-cholesterol plasma levels. METHODS: Participants (non-ST-segment elevation MI, non-STEMI, n = 41; STEMI, n = 37; non-MI patients, n = 33) from a prospective follow-up study enrolling patients with acute chest pain were matched for age and plasma HDL cholesterol...

BACKGROUND: Given the ongoing burden of cardiovascular disease and an ageing population, physical activity in patients with coronary artery disease needs to be emphasized. This study assessed whether sedentary behaviour and physical activity levels differed among older patients (≥75 years) following percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) consisting of ST-segment elevation myocardial infarction (STEMI) and non STEMI (NSTEMI) versus an elective admission control group of stable angina patients...

INTRODUCTION: Despite cardiovascular diseases having grown to epidemic proportions, there are few studies from India pertaining to Acute Coronary Syndrome (ACS), more so from the region of Purvanchal which is less developed with more poverty. Our study is first of its kind in this region of patients presenting for the first time with ACS. AIM: The present study was undertaken to study the clinical and angiographic characteristics of ACS patients of Purvanchal. MATERIALS AND METHODS: This was a prospective cohort study of 100 patients admitted with ACS...

BACKGROUND: Early determination of the acute etiology of cardiac arrest could help guide resuscitation or post-resuscitation care. In experimental studies, quantitative measures of the ventricular fibrillation waveform distinguish ischemic from non-ischemic etiology. METHODS: We investigated whether waveform measures distinguished arrest etiology among adults treated by EMS for out-of-hospital ventricular fibrillation between January 1, 2006-December 31, 2014. Etiology was classified using hospital information into three exclusive groups: acute coronary syndrome (ACS) with ST elevation myocardial infarction (STEMI), ACS without ST elevation (non-STEMI), or non-ischemic arrest...

Prasugrel, a potent thienopyridine, achieves stronger inhibition of platelet activation than clopidogrel. However, onset of inhibition is significantly delayed in patients with acute ST-elevation myocardial infarction (STEMI), as haemodynamic instability and morphine application seem to exhibit significant influence. Since rapid onset of effect was demonstrated in non-STEMI patients when prasugrel was administered only after percutaneous coronary intervention (PCI) without increasing cardiovascular event rates we assessed the efficacy of prasugrel loading immediately after PCI for STEMI instead of pre-loading before revascularisation...

COMPARATIVE STUDY
A I Macfarlane, D Rudd, E Knight, L A G Marshman, E P Guazzo, D S Anderson
: Prior studies have suggested that elevated serum Troponin-I (TnI) levels immediately after non-cardiac surgical procedures (8-40%) represent subclinical cardiac stress which independently predicts increased 30-day mortality. Routine post-operative TnI monitoring has therefore been suggested as a standard of care. However, no prior studies have focussed on elective degenerative spine surgery, whilst few have measured pre-op TnI. Further, prolonged prone positioning could represent an additional, independent, cardiac stress...

OBJECTIVE: Early clinical presentation of ST-segment-elevation myocardial infarction (STEMI) and non-ST-segment-elevation myocardial infarction affects patient management. Although local inflammatory activities are involved in the onset of MI, little is known about their impact on early clinical presentation. This study aimed to investigate whether local inflammatory activities affect early clinical presentation. APPROACH AND RESULTS: This study comprised 94 and 17 patients with MI (STEMI, 69; non-STEMI, 25) and stable angina pectoris, respectively...

Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome. It occurs predominantly among younger females, typically in the absence of atherosclerotic coronary artery disease. Presentations vary greatly and this condition can be fatal. Given its rarity, there are no management guidelines. We present six patients with SCAD with different presentations and treatment approaches as examples in our literature review. Two patients presented with ST elevation myocardial infarction (STEMI), two with non-STEMI (NSTEMI), and two with cardiac arrest...

BACKGROUND: Health care administrative databases are useful for assessing the population-level burden of disease and examining issues related to access, costs and quality of care. In these databases, the diagnoses and procedures are coded with the use of the World Health Organization International Classification of Diseases (ICD). We examined the validity of 2 ICD-10 coding definitions for categorizing patients with acute myocardial infarction (MI) as having ST-elevation MI (STEMI) or non-ST-elevation MI (non-STEMI)...

REVIEW
Maria Dorobantu, Stefan Bogdan
With the ageing of the general population, clinicians are facing with increased frequency the challenge of administering parenteral anti-coagulation therapy in the elderly, the main indications being venous thromboembolism (VTE), acute coronary syndromes (ACS), atrial fibrillation and bridging therapy. Assessing the risk/benefit ratio is always difficult in this category of patients, because of the higher risk for hemorrhagic events, although in most cases the benefit outweighs the risk, especially in the setting of VTE...
