Myocardial infarction due to coronary embolism after mechanical aortic valve replacement: a case report.

Prosthetic valve thrombosis (PVT) in aortic valve and its complication coronary embolism is a very rare condition. Diagnosis and treatment process is challenging. We present a young patient with acute myocardial infarction who underwent mechanical aortic valve replacement (AVR) operation one month earlier.

Effects of Vitamin D Levels on Long-Term Coronary Events in Patients with Proven Coronary Artery Disease: Six-Year Follow-Up.

Although some clinical studies have claimed that low-dose vitamin D (Vit-D) increases the risk of long-term cardiac events, in others, no association was found. To better understand the impact of Vit-D levels on long-term cardiac events in coronary artery disease patients, this study was designed. There were 408 patients with coronary artery disease (CAD).

Evaluation of the inflammatory parameters for predicting stent thrombosis.

Objectives: Recent research demonstrated that classic inflammatory mediators were responsible for the development of stent thrombosis. We aimed to examine the relationship between predictors such as basophils, mean platelet volume (MPV), and vitamin D, which represented allergic, inflammatory, and anti-inflammatory states, and stent thrombosis after percutaneous coronary intervention.

Methods: In this observational case-control study, patients (n: 87) with ST-elevated myocardial infarction (STEMI) with stent thrombosis formed group 1, and (n = 90) with STEMI without stent thrombosis formed group 2.

The relationship between H2FPEF score and contrast induced nephropathy in patients with ST elevation myocardial infarction.

In the present study, we aimed to investigate the relationship between H2FPEF score and Contrast Induced Nephropathy (CIN) in patients with myocardial infarction with ST segment elevation (STEMI). A total of 355 patients who had been diagnosed with ST elevation-myocardial infarction and undergone primary coronary angioplasty were retrospectively included in the study. The patients were divided into two groups according to the presence of CIN and these groups were compared in terms of baseline characteristics and laboratory findings.

The predictive value of PRECISE-DAPT score for arrhythmic complications in patients with ST-elevation myocardial infarction.

Objective: To investigate the predictive value of the PRECISE-DAPT score for the development of arrhythmias in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.

Method: A total of 706 patients with a diagnosis of ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention were enrolled to the study. The patients were divided into two groups according to the PRECISE-DAPT score (PRECISE-DAPT score ≥25 and PRECISE-DAPT score <25).

Outcomes of survivors of ST-segment elevation myocardial infarction complicated by out-of-hospital cardiac arrest: a single-center surveillance study.

Objective: The aim of the present study was to evaluate in-hospital and long-term outcomes of ST-segment elevation myocardial infarction (STEMI) survivors who experienced out-of-hospital cardiac arrest (OHCA) and underwent primary percutaneous coronary intervention (PCI) at a high-volume center within the STEMI network.

Methods: The records of 2681 consecutive STEMI patients who underwent primary PCI between January 2009 and December 2014 at a single center in the STEMI network were retrospectively analyzed. Patients with STEMI complicated by OHCA were compared with a reference group of STEMI patients who did not experience OHCA.

Clinical usefulness of red cell distribution width to angiographic severity and coronary stent thrombosis.

Background: Red cell distribution width (RDW) is a quantitative measurement and shows heterogeneity of red blood cell size in peripheral blood. RDW has recently been associated with cardiovascular events and cardiovascular diseases, and it is a novel predictor of mortality. In this study, we aimed to evaluate the clinical usefulness of measuring RDW in patients with coronary stent thrombosis.

The accuracy of combined use of troponin and red cell distribution width in predicting mortality of patients with acute pulmonary embolism.

Background: Cardiac troponins and red cell distribution width (RDW) are associated with increased mortality in acute pulmonary embolism (PE). In this study, we aimed to investigate the accuracy of the combined use of troponin and RDW in predicting short-term mortality in acute PE patients.

Methods: The data of 201 patients with the diagnosis of acute PE were retrospectively analyzed.

Relation of Low T3 to One-Year Mortality in Non-ST-Elevation Acute Coronary Syndrome Patients.

Background: Low T3 which is defined as decreased triiodothyronine (T3) and normal thyroid-stimulating hormone (TSH) and thyroxin (T4) levels is present in many acute diseases and is related to increased mortality. We studied low T3 level's relation to long-term mortality in non-ST-elevation acute coronary syndrome (NSTE-ACS) patients.

Methods: T3, T4, and TSH levels of consecutive NSTE-ACS patients were measured.

Relation of contrast nephropathy to adverse events in pulmonary emboli patients diagnosed with contrast CT.

Objective: Limited data exist on the incidence of contrast induced nephropathy (CIN) and its impact on in-hospital prognosis of patients diagnosed with acute pulmonary embolism (APE) using contrast computerized tomography pulmonary angiography (CTPA). In this study, we examined the frequency of nephropathy after CTPA in APE patients and its link to in-hospital adverse outcomes.

Methods: This was a retrospective study of 189 patients (mean age 67+16years, 48% male) with APE who underwent CTPA.

Impact of Nonalcoholic Fatty Liver Disease on Myocardial Perfusion in Nondiabetic Patients Undergoing Primary Percutaneous Coronary Intervention for ST-Segment Elevation Myocardial Infarction.

Limited data exist on the role of nonalcoholic fatty liver disease (FLD) as a potential independent risk factor in the setting of acute coronary syndromes. The aim of this study was to evaluate the impact of FLD on myocardial perfusion and inhospital major adverse cardiac events (MACE) in the setting of ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). We examined 186 consecutive nondiabetic patients (mean age 58 ± 11 years and 76% men) who underwent primary PCI for STEMI by ultrasound within 72 hours of admission.

Differentiation between Transudate and Exudate in Pericardial Effusion has almost no Diagnostic Value in Contemporary Medicine.

Background: The biochemical analysis of pericardial fluid for differentiating transudate from exudate is often ordered and interpreted according to the criteria extrapolated from pleural effusions. However, the validity of this discrimination when applied to pericardial effusion is under question.

Methods: Patients who underwent pericardiocentesis between January 2004 and February 2014 were identified.

Fragmented QRS on Admission Electrocardiography Predicts Long-Term Mortality in Patients with Non-ST-Segment Elevation Myocardial Infarction.

Background: Early diagnosis and identification of high-risk non-ST elevation myocardial infarction (NSTEMI) is an important issue. Fragmented QRS (fQRS) complexes are defined as various RSR' patterns on 12-lead resting electrocardiography (ECG). Previous studies revealed that fQRS is related with increased ventricular arrhythmias and cardiovascular mortality.

From wide QRS tachycardia to a diagnostic surprise.

A 29-year old male patient presented with a hemodynamically significant ventricular tachycardia. Despite a comprehensive examination, the correct diagnosis was unfortunately established after two years. We discuss why the correct diagnosis was initially overlooked in physical examination, electrocardiogram, echocardiography and cardiac magnetic resonance imaging, and which findings led the cardiologists to misdiagnose the patient.

The relationship between fragmentation on electrocardiography and in-hospital prognosis of patients with acute myocardial infarction.

Background: In patients with acute ST elevation myocardial infarction (STEMI), QRS fragmentation was determined as one of the indicators of mortality and morbidity. The development of fragmented QRS (fQRS) is related to defects in the ventricular conduction system and is linked to myocardial scar and fibrosis.

Material And Methods: We prospectively enrolled 355 consecutive patients hospitalized in the coronary intensive care unit of our hospital with STEMI between the years 2010 and 2012 and their electrocardiographic features and the frequency of in-hospital cardiac events were evaluated.
