BACKGROUND: Infarct heterogeneity, as assessed by determination of the peri-infarct zone (PIZ) by cardiac magnetic resonance imaging, has been shown to be an independent predictor for the development of cardiac arrhythmias and mortality post myocardial infarction (MI). The temporal evolution of the PIZ post MI is currently unknown. Thus, the main objective of our study was to describe the temporal evolution of the PIZ over a 6 month time period in contemporarily managed ST elevation myocardial infarction (STEMI) patients...

Intra-aortic balloon pump (IABP) is commonly used as a cardiac assist device in various clinical situations: cardiogenic shock, mechanical complications of acute myocardial infarction, high risk percutaneous coronary interventions, coronary artery bypass graft surgery and refractory unstable angina and ventricular arrhythmias as bridge to therapy. Although current data support its safety, there is limited or no support for its efficacy. We present the case of spinal cord infarction after IABP use in a patient who presented with ST elevation myocardial infarction and cardiac arrest and we discuss the potential mechanism of such a devastating complication...

INTRODUCTION: The propeptide of brain natriuretic peptide (ProBNP) is used for the diagnosis of left ventricle dysfunction and heart failure. In patients with an Acute Coronary Syndrome (ACS) it can contribute to both short and long term prognosis of cardiovascular events that could be very important for management and therapy of these patients. AIM: The aim of this study was to evaluate the prognostic value of ProBNP for the clinical course after an acute coronary syndrome, compared with that of cardiac troponine T (cTnT) and the risk stratification of patients with acute coronary syndrome, both during hospitalization and six months later...

Percutaneous coronary intervention (PCI) is effective in opening the infarct related artery and restoring thrombolysis in myocardial infarction flow 3 (TIMI-flow 3) in large majority of ST-elevation myocardial infarction (STEMI). However there remain a small but significant proportion of patients, who continue to manifest diminished myocardial reperfusion despite successful opening of the obstructed epicardial artery. This phenomenon is called no-reflow. Clinically it manifests with recurrence of chest pain and dyspnea and may progress to cardiogenic shock, cardiac arrest, serious arrhythmias and acute heart failure...

BACKGROUND: Bioabsorbable cardiac matrix (BCM) is a novel device that attenuates adverse left ventricular (LV) remodeling after large myocardial infarctions in experimental models. OBJECTIVES: This study aimed to analyze whether BCM, compared with saline control, would result in less LV dilation and fewer adverse clinical events between baseline and 6 months. METHODS: In an international, randomized, double-blind, controlled trial, 303 subjects with large areas of infarction despite successful primary percutaneous coronary intervention (PCI) of ST-segment elevation myocardial infarction (STEMI) were randomized 2:1 to BCM or saline injected into the infarct-related artery 2 to 5 days after primary PCI...

Fractional flow reserve (FFR) measurement provides useful hemodynamic assessment of intermediate coronary stenoses affecting long term outcomes. While the gold standard remains intravenous adenosine, intracoronary (IC) bolus administration of adenosine is routinely used in clinical practice because of its ease of use and lower dose providing comparative hyperemia with the most common side effect being a transient atrioventricular block. A 62year old male underwent left heart catheterization after ruling in for non-ST elevation myocardial infarction (NSTEMI)...

The effectiveness of drug remaxol inclusion in the scheme of treatment of patients with myocardial infarction on the background of degree III - III acute cardiac insufficiency was evaluated by the analysis of clinical and laboratory data of 126 patients with newly diagnosed acute myocardial infarction including ST-segment elevation on the background of acute cardiac insufficiency. Depending on the regimen, patients were divided into two groups. The first (control) group included 60 patients who received conventional thrombolytic therapy; the second (main) group included 66 patients which, after thrombolytic therapy, received remaxol (single daily intravenous administration, 400 mL at 3 - 4 mL/min rate) with controlled central venous pressure, arterial pressure, and diuresis...

BACKGROUND: Accelerated idioventricular rhythm (AIVR) is a common arrhythmia observed in patients with ST segment elevation myocardial infarction (MI). It is not clear how much value AIVR has in predicting successful reperfusion, since there have been conflicting data regarding this in the past. Streptokinase (STK) even today is the commonest thrombolytic agent used in the public health care set-up in India.(1) Most data for the use of STK are from the 1990s, which had showed that at best it is effective in only 50% of patients in restoring adequate flow...

BACKGROUND: In regional systems of ST-segment elevation myocardial infarction (STEMI) care, patients presenting to hospitals without percutaneous coronary intervention (PCI) are transferred to PCI-capable hospitals for primary PCI. Repatriation, a practice whereby such patients are transferred back to non-PCI referral hospitals after reperfusion is prevalent in many jurisdictions, yet little is known of this practice and its safety. METHODS: We studied 979 consecutive STEMI patients transported from the emergency department and catchment area of two non-PCI hospitals in Ontario, Canada to a regional PCI-hospital for primary PCI between January 2008 and June 2014...

Background Infant and neonatal myocardial infarction (MI) has been described in association with congenital heart disease, coronary artery abnormalities, myocarditis, and tumors. MI in the perinatal period in a structurally normal heart and with ventricular arrhythmia as a presenting feature has not been thoroughly described. Published case reports describe treatment methods extrapolated from adult MI. However, due to the rare occurrence, the most appropriate acute treatment for both MI and ventricular arrhythmia in newborn infants remains unknown...
