Objective: To investigate the effect of intracoronary administration of nicorandil prior to primary percutaneous coronary intervention (PPCI) on myocardial perfusion and short-term clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI). Methods: A total of 158 patients with STEMI undergoing PPCI from January 2014 to December 2015 in Fuzhou General Hospital were enrolled consecutively in this prospective controlled randomized trial. Patients were assigned into three groups with random number table: the nicorandil group (patients received intracoronary administration of 6 mg nicorandil after guide wire or balloon successfully crossed the target lesion, n=53), the nitroglycerin group (patients received intracoronary administration of 300 μg nitroglycerin after after guide wire or balloon successfully crossed the target lesion, n=52) and the control group(patients received routine treatment, n=53)...

We report the case of a woman in her 70s presenting to the emergency department with syncope, troponemia, and an electrocardiogram with deep symmetric T-wave inversions in V2 and V3 and prolonged QTc. Her presentation was concerning for acute coronary syndrome, Wellens syndrome in particular, given the elevated troponin levels, lack of ST segment changes, and characteristic T-wave findings. The diagnosis was confirmed with angiography that showed a critical left anterior descending (LAD) artery occlusion. Since myocardial infarction does not typically present with syncope, we explored the differential diagnoses for T-wave inversions, which include electrolyte abnormalities, medications, intracranial hemorrhage, pulmonary embolism, and other cardiac diseases that were ruled out in our patient...

Atrial fibrillation (AF) is the most common supraventricular arrhythmia following ST elevation myocardial infarction (STEMI). Oxidative stress and inflammation may cause structural and electrical remodeling in the atria making these critical processes in the pathology of AF. In this study, we aimed to evaluate the association between total oxidative status (TOS), total antioxidative capacity (TAC) and high-sensitivity C-reactive protein (hs-CRP) in the development of AF in patients presenting with STEMI. This prospective cohort study consisted of 346 patients with STEMI...

OBJECTIVES: To examine whether the CADILLAC risk score is an effective method of patient stratification for early discharge following ST elevation myocardial infarction (STEMI). BACKGROUND: Patients with STEMI are typically hospitalized to monitor for serious complications such as arrhythmias, heart failure, and reinfarction. Optimal length of stay is unclear. Whether low risk patients can be safely discharged before 72 hr of hospitalization is unclear. METHODS: Patients with STEMI who underwent successful PCI were retrospectively stratified using CADILLAC risk score to low risk (n = 123) and intermediate to high risk (n = 105)...

BACKGROUND/OBJECTIVES: The role of intravenous (IV) beta-blockers in conjunction with percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) remains unclear. We therefore conducted a meta-analysis to assess their role in the acute phase of STEMI. METHODS: We systematically searched the Cochrane Libraries, Medline, and EMBASE for RCTs comparing IV beta-blockers with inactive controls in STEMI patients undergoing PCI. The primary outcome was left ventricular ejection fraction (LVEF)...

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...

REVIEW
Sanjiv Gupta, Madan Mohan Gupta
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...

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)...
