Long-term outcomes in very young patients with myocardial infarction with non-obstructive coronary arteries.

Myocardial infarction (MI) with non-obstructive coronary arteries (MINOCA) covers an expanding group of patients over recent years. Previous studies showed considerable risks of outcomes in this group. However, there is a lack of evidence in young patients with MINOCA.

Long-Term Change in Flow Rates in Patients with Coronary Slow Flow.

Introduction: Coronary slow flow (CSF) is a condition characterized by impaired blood flow rates in the coronary arteries. It can result in severe cardiovascular outcomes. There is no sufficient evidence regarding the certain etiology and reversibility of slow flow patterns and changes in frame counts with long-term management.

Outcomes of Coronary Artery By-Pass Grafting Under Dual Antiplatelet Therapy in ST Elevated Myocardial Infarction.

Patients with recent myocardial infarction (MI) or percutaneous coronary interventions (PCI) have a higher ischemic risk in addition to perioperative bleeding risk when undergoing coronary artery bypass grafting (CABG). Data regarding preoperative dual antiplatelet therapy (DAPT) failed to create a clear recommendation. In the present study, we assessed the relationship between preoperative DAPT use and adverse outcomes, particularly in ST-elevation MI (STEMI) patients.

Balloon Angioplasty Versus Stenting in Patients With ST-Elevated Myocardial Infarction Before Subsequent Coronary Artery By-Pass Grafting.

Decision of revascularization strategy in patients who require coronary artery bypass grafting (CABG) following primary percutaneous coronary interventions (PCI) is challenging due to the pros and cons of only-ballooning and stenting. In this study, we aimed to compare the outcomes of only-balloon-angioplasty to stenting in primary PCI in patients with ST elevated myocardial infarction (STEMI) who required a subsequent CABG. We retrospectively analyzed 350 consecutive STEMI patients who needed CABG in addition to primary balloon angioplasty (n = 160) and stenting strategy (n = 190).

The association of inflammatory markers and echocardiographic parameters in Behçet's disease.

The main objective of the current study is to find out if any association exists between specific inflammatory markers such as homocysteine (Hcy) and pentraxin-3 (PTX-3) and cardiac involvement determined by means of echocardiographic parameters in patients with Behçet disease (BD). From January 2011 to January 2012, a total of 62 Behçet's patients were enrolled in the study. Thirty-two healthy subjects constituted the control group.

Systemic inflammatory activation in patients with acute coronary syndrome secondary to nonatherosclerotic spontaneous coronary artery dissection.

Objective: Pathological studies have suggested that local inflammation, particularly eosinophilic infiltration of the adventitia, could be related to nonatherosclerotic spontaneous coronary artery dissection (NA-SCAD). However, the role of systemic inflammation in the pathogenesis of NA-SCAD remains unknown. Our aim was to investigate systemic inflammatory activation in patients with an acute coronary syndrome (ACS) secondary to NA-SCAD.

Long term evaluation of electromechanical delay in patients with atrial septal defect after transcatheter closure.

Some studies have been showed that electromechanical delay, which may pose an increased tendency to atrial fibrillation, may prolong in patients with various clinical conditions. In addition, the electromechanical delay in patients with secundum type atrial septal defect (ASD) compared to healthy people have been reported previously. Therefore, in the present study, we prospectively evaluated the mid-term and long-term effects of the transcatheter closure of secundum type ASD on the lateral atrial conduction time (PA), septal PA, tricuspid PA, left and right intra-atrial electromechanical delay (ILeft-EMD and IRight-EMD, respectively) and inter-atrial electromechanical delay (IA-EMD) measured by means of Doppler echocardiography.

Association of Interleukin-1 Gene cluster polymorphisms with coronary slow flow phenomenon.

Objective: Coronary slow flow phenomenon (CSFP) is characterized by the decreased rate of contrast progression in epicardial coronary arteries in the absence of significant coronary stenosis. Mounting evidence has showed a significant association between inflammation and CSFP severity. This study aimed to evaluate possible associations between interleukin-1 receptor antagonist (IL-1ra) gene variable number tandem repeat (VNTR), IL-1ß -511 single nucleotide (SNP), and IL-1ß+3954 SNP mutations with CSFP.

Assessment of electrocardiographic parameters in adult patients undergoing extracorporeal shockwave lithotripsy.

Objective: Extracorporeal shock wave lithotripsy (ESWL) is a safe and effective treatment for urinary tract calculi. While serious side effects are rare, transient cardiac arrhythmias may occur. New electrocardiographic (ECG) parameters, such as P wave dispersion (PWD), QT dispersion (QTd), T peak to T end (Tp-e) interval, Tp-e interval/QT ratio, and Tp-e interval/corrected QT ratio have been defined to help predict atrial and ventricular arrhythmias.

Clinical presentation and outcomes in type IV dual left anterior descending artery anomaly.

Type IV dual left anterior descending artery (LAD) anomaly constitutes a rare subset of coronary anomalies in which the anterior and anterolateral wall of the left ventricle is supplied by a short LAD originating from the left coronary artery along with a long LAD that originates from the right sinus of Valsalva. Albeit rare, the angiographic presentation is challenging since the appearance of the short LAD is similar to a total occlusion beyond first few diagonal or septal branches. Here, we present a series of four cases with type IV dual LAD anomaly with different clinical and angiographic presentations.

Congenital coronary artery anomalies in adults: review of 111 cases from a single-centre experience.

Background: Coronary artery anomalies are a heterogeneous group of congenital disorders presenting with a wide spectrum of symptoms, ranging from vague chest pain to sudden cardiac death. Despite available data, there is no consensus about the classification, nomenclature, and outcomes of coronary anomalies in the normally connected heart. In this study, we aimed to investigate clinical and angiographic characteristics of coronary arterial anomalies, as well as the frequency of atherosclerotic involvement in anomalous coronaries, diagnosed at a tertiary referral centre.

Prognostic Value of QRS Fragmentation in Patients with Acute Myocardial Infarction: A Meta-Analysis.

Aims: Fragmented QRS has emerged as a novel electrocardiographic parameter associated with adverse clinical events in various diseases. The aim of this study was to investigate the association of fQRS with in-hospital and long-term cardiovascular events in patients with ST-segment elevation myocardial infarction (STEMI) and non-ST segment elevation myocardial infarction (NSTEMI).

Methods And Results: We searched PubMed, Embase, Web of Science, and Cochrane Library up to October 2015 for eligible studies.

Association of contrast-induced nephropathy with bare metal stent restenosis in STEMI patients treated with primary PCI.

Background: Contrast induced nephropathy (CIN) has been proven as a clinical condition related to adverse cardiovascular outcomes. However, relationship between CIN and stent restenosis (SR) remains unclear. In this study, we aimed to investigate the association of CIN with SR rates after primary percutaneous coronary intervention (PCI) and bare metal stent (BMS) implantation.

Assessment of Prognostic Value of Neutrophil to Lymphocyte Ratio and Platelet to Lymphocyte Ratio in Patients with Pulmonary Embolism.

Background: Acute pulmonary embolism is a serious medical condition that has a substantial global impact. Inflammation plays a role in the pathophysiology and prognosis of acute pulmonary embolism (APE). The aim of the present study was to investigate the prognostic value of admission parameters for complete blood count (CBC) in APE.

Objective: We aimed to assess the risk factors for coronary artery ectasia (CAE) as infarct-related artery (IRA) and short-term and 1 year outcomes.

Backgrounds: CAE in patients with ST elevated myocardial infarction (STEMI) is a rare condition with a limited knowledge about the risk factors associated with coronary artery ectasia in STEMI and prognosis after primary percutaneous coronary interventions.

Methods: Retrospectively, 1655 patients with STEMI who were undergone coronary angiography were included in this study.

Predictors of in-hospital mortality in octogenarian patients who underwent primary percutaneous coronary intervention after ST segment elevated myocardial infarction.

Aim: Octogenarian patients have higher mortality and morbidity rates after acute coronary syndromes. Risk factors for in-hospital mortality in the primary percutaneous coronary intervention (PCI) era were underrepresented in previous studies. In the present study, we aimed to assess the risk factors of in-hospital mortality after primary PCI in this population.

A Late Sequela of the David Procedure: Left Main Coronary Artery Compression and Myocardial Infarction due to Pseudoaneurysm Formation.

Valve-sparing root replacement (the David procedure) is a valuable alternative to conventional aortic root replacement with a composite graft, especially in patients whose aortic valve leaflets have not been altered. However, reintervention rates are higher than are those associated with composite graft implantation. In this report, we present the case of a patient who had undergone valve-sparing root replacement 2 years earlier and was admitted to our hospital with myocardial infarction and cardiogenic shock secondary to coronary ostial button dissection, aortic pseudoaneurysm formation, and severe left main coronary artery compression.

Association of admission serum laboratory parameters with new-onset atrial fibrillation after a primary percutaneous coronary intervention.

Objectives: New-onset atrial fibrillation (NOAF) during hospitalization is considered a frequent complication associated with worse outcomes in the setting of ST-segment elevation myocardial infarction (STEMI). We aimed to investigate the association of admission serum laboratory parameters, neutrophil to lymphocyte ratio (NLR), and monocyte to high-density lipoprotein ratio (MHR) with NOAF in STEMI patients treated with a primary percutaneous coronary intervention (PCI).

Patients And Methods: A total of 621 patients who were hospitalized with a diagnosis of STEMI and treated with primary PCI were retrospectively enrolled in the study.

CHA2DS2-VASc Score is a Predictor of No-Reflow in Patients With ST-Segment Elevation Myocardial Infarction Who Underwent Primary Percutaneous Intervention.

Thrombosis and distal embolization play crucial role in the etiology of no-reflow. CHA2DS2-VASc score is used to estimate the risk of thromboembolism in patients with atrial fibrillation. We tested the hypothesis that CHA2DS2-VASc can predict no-reflow among patients who underwent primary percutaneous coronary intervention (PCI).

Assessment of Short-term Blood Pressure Variability in Patients With Ascending Aortic Dilatation.

Background: Blood pressure variability (BPV) is a novel parameter related to adverse cardiovascular findings and events, especially in hypertensive patients. The aim of the present study was to investigate the relationship between short-term BPV and ascending aortic dilatation (AAD).

Hypothesis: Hypertensive patients with AAD may exhibit higher short-term BPV compared to hypertensive patients with normal diameter ascending aorta and BPV may be correlated with aortic sizes.

Monocyte to high-density lipoprotein ratio as a new prognostic marker in patients with STEMI undergoing primary percutaneous coronary intervention.

Background: Monocyte count to high-density lipoprotein ratio (MHR) has recently emerged as an indicator of inflammation and oxidative stress in the literature. We aimed to investigate the prognostic value of MHR in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention (PCI).

Methods: A total of 513 patients who were hospitalized with diagnosis of acute ST-segment elevation myocardial infarction and treated with primary PCI were retrospectively enrolled in the study.
