Acute myocardial infarction (AMI) has a high mortality rate and poor prognosis for patients. The primary causes of death are arrhythmia and heart failure. For patients admitted because of myocardial infarction, various risk evaluations are initiated to foresee possible complications. The thrombolysis in myocardial infarction (TIMI) risk score, which can be used to predict the prognosis and the need for revascularisation, is the most convenient and commonly used system, but is inadequate for AMI patients on admittance...

BACKGROUND: The no-reflow phenomenon is a serious complication after primary percutaneous coronary intervention (PCI) for ST-elevation Myocardial Infarction (STEMI). Coronary artery ectasia (CAE) may increase the risk of no-reflow, however, only limited data is available on the potential impact of CAE. The aim of this study was to determine the potential association between CAE and no-reflow after primary PCI. METHODS: A case control study was performed based on a prospective cohort of STEMI patients from January 2000 to December 2011...

Coronary allograft vasculopathy (CAV) is a major cause of mortality in late-stage orthotopic heart transplantation (OHT) patients. Recent evidence has shown that myocardial perfusion reserve (MPR) derived from vasodilator cardiovascular magnetic resonance imaging (vCMR) and global longitudinal strain (GLS) from transthoracic echocardiography (TTE) are useful to detect CAV. However, previous studies have not comprehensively addressed whether these parameters are confounded by allograft rejection, myocardial scar/fibrosis, or allograft dysfunction...

The preferred treatment for patients with ST elevation myocardial infarction (STEMI) is primary percutaneous coronary intervention (PCI). However, not all patients improve or maintain heart function following primary PCI, and certain patients may experience decreased heart function. The present study investigated factors associated with left ventricular (LV) dysfunction, and improvement or deterioration of LV ejection fraction (LVEF) at follow-up echocardiography following successful primary PCI. The clinical outcomes following primary PCI were also investigated...

Introduction: No-reflow is one of the major complications of primary PCI in patients with acute ST elevation myocardial infarction. This phenomenon is associated with adverse outcomes in these patients. In the current study, we evaluated the effectiveness of CHA2DS2-VASc score in predicting no-reflow phenomenon. CHA2DS2-VASc score is a risk stratification method to estimate the risk of thromboembolism in patients with atrial fibrillation. Methods: In total, 396 patients with ST elevation myocardial infarction who had undergone primary PCI were evaluated in our study...
