Interatrial block (IAB) represents delay or block of conduction between the atria. IAB has been shown to predict the development or recurrence of atrial fibrillation (AF) in various clinical scenarios. Few studies have examined the correlation between coronary artery disease and the prevalence of IAB and its impact on AF. The aim of this study was to determine if specific coronary artery lesions (location and number) are associated with the presence of IAB and development of new-onset AF. Retrospective analysis of patients presenting with non-ST-segment elevation myocardial infarction (NSTEMI) to our institution...

AIMS: Microvascular obstruction (MVO) is associated with a worse prognosis in patients with ST-elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PCI). However, data about incidence, clinical outcome and correlates of MVO in latecomers after STEMI are still lacking. METHODS: We prospectively enrolled consecutive patients that were latecomers after STEMI (symptoms onset >12h) undergoing PCI. We performed an angiographic analysis to assess the occurrence of MVO [defined as TIMI flow grade ≤2 or 3 with a myocardial blush grade <2]...

Dysglycemia on admission is known to predict the prognosis of ST-segment elevation myocardial infarction (STEMI). Recently, hypoxic liver injury (HLI) has been proposed as a novel prognosticator for STEMI. We evaluated the prognostic impact of combined dysglycemia and HLI at the time of presentation in patients with STEMI who underwent primary percutaneous coronary intervention. From 2007 to 2014, 1,525 consecutive patients (79% men, mean age 61 years) who underwent primary percutaneous coronary intervention for STEMI in the INTERSTELLAR (Incheon-Bucheon Cohort of Patients Undergoing Primary PCI for Acute ST-Elevation Myocardial Infarction) cohort were analyzed retrospectively...

In this study, we explored the microRNAs responsible for the regulation of PAI-1 during LPS-stimulated inflammation in human aortic endothelial cells, subsequently studied the effect of a newly synthesized mitochondria-targeted esculetin (Mito-Esc) that was shown for its anti-atherosclerotic potential in modulating PAI-1 levels and its targeted miRs during angiotensin-II-induced atherosclerosis in ApoE(-/-) mice. LPS-stimulated PAI-1 was accompanied with an upregulation of miR-19b and down-regulation of miR-30c...

BACKGROUND: Electrocardiography (ECG) is still one of the first tests performed at admission, mostly in patients (pts) with chest pain or dyspnea. The aim of this study was to assess the correlation between electrocardiographic abnormalities and cardiac biomarkers as well as echocardiographic parameter in patients with acute pulmonary embolism. METHODS: We performed a retrospective analysis of 614 pts. (F/M 334/280; mean age of 67.9 ± 16.6 years) with confirmed acute pulmonary embolism (APE) who were enrolled to the ZATPOL-2 Registry between 2012 and 2014...

BACKGROUND AND AIM: It was hypothesized that the pattern of coronary occlusion (thrombus composition) might contribute to the onset of ventricular arrhythmia and sudden cardiac death (SCD) in myocardial infarction (MI). METHODS: The TIDE (Thrombus and Inflammation in sudden DEath) study included patients with angiographically-proven acute coronary occlusion as the cause of a ST elevation MI (STEMI) complicated by Sudden Cardiac Death (SCD group) or not (STEMI group)...

AIMS: Recent frequency-domain optical coherence tomography studies showed that a complete removal of thrombotic materials is rarely achieved after percutaneous coronary interventions for ST segment elevation myocardial infarction. Residual intrastent thrombus can embolize distally leading to microcirculatory injury. The aim was to find a possible correlation between residual intrastent thrombus and angiographic indexes of myocardial reperfusion. METHODS: The population consisted of 128 ST segment elevation myocardial infarction patients enrolled in the COCTAIL II trial...

Although cardiotoxicity has been recognized as an adverse effect of cyclosporine A (CSA), no information exists regarding sex specificity of CSA cardiotoxicity. We tested the hypothesis that left ventricular (LV) and electrocardiographic (ECG) effects of CSA and related inflammatory/histopathological derangements are sex related. CSA reduced the LV slope of end-systolic pressure volume relationship and increased isovolumic relaxation constant. These effects were more pronounced in male compared to female rats, suggesting LV systolic and diastolic dysfunction...

Myocarditis is an inflammatory disease of the myocardium with heterogeneous clinical manifestations and progression. In clinical practice, although there are many methods of diagnosis of acute myocarditis, the diagnosis remains an embarrassing dilemma for clinicians. The authors report the case of 9-month-old infant who was brought to the Pediatric Emergency Department with sudden onset dyspnea. Examination disclosed heart failure and resuscitation was undertaken. The electrocardiogram showed an ST segment elevation in the anterolateral leads with a mirror image...

Characteristic ECG changes with hypercalcemia include shortening of the QoT, QaT, and QeT intervals which are measured from the beginning of the QRS complex to the origin (O), apex (A), and end (E) of the T wave respectively. At very high serum calcium levels ECG changes include slight prolongation of the PR and QRS intervals, T wave flattening or inversion, and the appearance of a J wave at the end of the QRS complex. We present a case of a 22year-old male, who had been bedbound for 5months following a severe motor vehicle collision, presenting with shortening of the QoT and QaT intervals leading to anterior ST elevation mimicking acute myocardial infarction...

INTRODUCTION: Neutrophil gelatinase-associated lipocalin (NGAL) is a glycoprotein released by damaged renal tubular cells and mature neutrophils. It is elevated in kidney injury, but also in patients with coronary artery disease (CAD) and myocardial infarction. We investigated the prognostic value of NGAL for total and cardiovascular mortality in patients undergoing coronary angiography without history of renal insufficiency at inclusion into the study. PARTICIPANTS: The LURIC study is an ongoing prospective cohort study of patients referred for coronary angiography and is designed to evaluate determinants of cardiovascular health...

Coronary no-reflow (NR) is observed in nearly half of ST segment elevation myocardial infarction (STEMI) patients who undergo a primary percutaneous coronary intervention (pPCI) despite epicardial coronary vessel patency. Several methods used to define NR include thrombolysis in myocardial infarction grade, corrected thrombolysis in myocardial infarction frame count, myocardial blush grade, ST-segment resolution, contrast echocardiography, and MRI. The aim of our study was to evaluate the relationship between NR and R-wave peak time (RWPT) measured from infarct-related artery leads METHOD: We enrolled 282 consecutive STEMI patients treated with pPCI in Kafkas University Hospital from January 2014 to January 2015...

Survivors of out-of-hospital cardiac arrest (OHCA) have high mortality and morbidity. An acute coronary event is the most common cause of sudden cardiac death. For this reason, coronary angiography is an important diagnostic and treatment strategy for patients with postcardiac arrest. This study aimed to identify the correlation between postreturn of spontaneous circulation (ROSC) on an electrocardiogram (ECG) and results of coronary angiography of OHCA survivors.We collected data from our OHCA registry from January 2010 to November 2014...

BACKGROUND: Positive T wave in lead aVR has been shown to predict an adverse in-hospital outcome in patients with anterior wall ST-segment elevation myocardial infarction (STEMI). However, the prognostic value of positive T wave in lead aVR on a long-term outcome has not been fully explored. METHODS: We performed a retrospective analysis of 190 consecutive patients with first anterior wall STEMI who underwent an emergent coronary angiogram. Patients were divided into those with positive T wave > 0 mV and those with negative T wave ≦ 0 mV in lead aVR...

The use of energy drinks, which often contain stimulants, is common among young persons, yet there have been few reports of adverse cardiac events. We report the case of a 27-year-old man who was admitted to our facility with an acute ST-segment elevation myocardial infarction in the setting of using energy drinks. Angiography revealed no obstructive coronary disease. The patient had elevation of cardiac troponin. Noninvasive testing with echocardiography and cardiac magnetic resonance imaging demonstrated both abnormalities in resting wall motion at the anterior apex along with late gadolinium enhancement of the anterior wall, respectively...

We describe a 54-year-old male with history of type II DM, hypertension and dyslipidemia during admission for bronchopneumonia discovered to have coarctation of the aorta and a persistent left superior vena cava (PLSVC) draining into the left atrium through the left superior pulmonary vein. The latter was thought to contribute to a transient ischemic attack and an episode of chest pain resulting in ST-segment elevation in the inferior leads. He was treated with coarctation stenting and percutaneous exclusion of the PLSVC with a vascular plug...

Wellens' syndrome is characterized by an electrocardiographic pattern of T-wave changes associated with a critical stenosis of the left anterior descending artery (LAD), which progresses to an extensive anterior myocardial infarction in the majority of cases. For this reason, its recognition and early treatment are extremely important. We report 2 cases of Wellens' syndrome: an 83-year-old male presenting with ill-characterized chest pain, biphasic T waves in V1-V3 during an asymptomatic period, negative cardiac biomarkers, and a 64% stenosis in LAD with a fractional flow reserve of 0...
