BACKGROUND AND PURPOSE: Cerebral cortical infarctions are often considered to be associated with more severe cognitive deficits than subcortical infarctions, but the evidence is conflicting. We compared early and late cognitive deficits between cortical and subcortical lesions. METHODS: Consecutive patients with first-ever cortical (n = 61) or subcortical (n = 71) cerebral infarctions were ...

Situs inversus with dextrocardia is a rare condition. Yet, the incidence of atheroclerosis and myocardial infarction in patients with dextrocardia is similar to that in general population. The diagnosis of acute myocardial infarction is somewhat tricky and difficult if the dextrocardia is not recognized. We present the electrocardiogram, coronary angiograms, ...

Primary percutaneous coronary intervention (PCI) in acute ST elevation myocardial infarction (STEMI) is a clinical challenge. Adequate thrombus removal before stenting is an important factor that predicts procedural success, and finally reflects to clinical outcomes. In the present report, 2 cases of acute STEMI underwent primary PCI. Coronary angiogram (CAG) ...

Atherosclerosis is a systemic vascular pathology that is preceded by endothelial dysfunction. Vascular inflammation "fuels" atherosclerosis and creates the milieu for episodes of intravascular thromboses. Thrombotic events in the coronary vasculature may lead to asymptomatic progression of atherosclerosis or could manifest as acute coronary syndromes or even sudden cardiac death. ...

Antiplatelet and antithrombotic agents significantly alter the clinical course of patients with acute coronary syndrome (ACS) and hence form the bedrock of the management pathway of this closely related continuum of coronary pathologies. The contemporary therapeutic armamentarium for the treatment of ACS now reflects the many technical and pharmacological advances ...

AIMS: Despite a successful surgical procedure and adherence to current recommendations, postoperative left ventricular (LV) dysfunction after mitral valve repair (MVr) for organic mitral regurgitation (MR) may still occur. New approaches are therefore needed to detect subclinical preoperative LV dysfunction. LV global longitudinal strain (GLS), assessed with speckle-tracking echocardiographic analysis, ...

Ventricular assist devices are electromechanical pumps used for circulatory support of patients with severe heart failure. Current ventricular assist device therapy provides a broad spectrum of support systems ranging from short-term to long-term devices. Echocardiography is an ideal modality to monitor patients undergoing mechanical circulatory support because it is less ...

BACKGROUND: The current European and American Guidelines differ with regard to the recommended level for the use of routine early angiography after fibrinolysis for STEMI. Previous meta-analyses on randomized controlled trials have supported the routine early approach, but its advantage may be because of an excessively low angiography rate among ...

Detection of arrhythmic atrial beats in surface ECGs can be challenging when they are masked by the R or T wave, or do not affect the RR-interval. Here, we present a solution using a high-resolution esophageal long-term ECG that offers a detailed view on the atrial electrical activity. The recorded ...

Myocardial reperfusion therapy remains the most effective strategy to limit infarct size and improve clinical outcome. However, reperfusion injury is still inevitable, and a number of strategies have been developed to ameliorate its lethal outcome. The beneficial roles of ischemic postconditioning (Ipost) have regained more interest in targeting myocardial reperfusion ...

Extensive damage of the myocardium following an acute myocardial infarction usually causes cardiogenic shock. A 66-year-old male patient was treated successfully by primary percutaneous transluminal coronary angioplasty (PTCA) following an acute anterior wall myocardial infarction with prior moderate LV systolic dysfunction and developing cardiogenic shock with intra-aortic balloon counterpulsation (IABP), ...

Vitiligo in association with autoimmune endocrine disorders, especially with hypothyroidism, is not uncommon. Some amount of pericardial effusion is usually present in long-standing/untreated hypothyroidism. Here we describe the case of young male with, long-standing progressive vitiligo, presenting with congestive cardiac failure due to dilated cardiomyopathy and primary hypothyroidism. Cardiac dysfunction ...

Cardiac troponins are the most sensitive and specific serum markers of myocardial cell injury, but they can also arise without apparent cardiac injury. Besides, acute cholecystitis may be associated with nonspecific ST-T wave changes in electrocardiography (ECG). The signs and symptoms of gallbladder and heart disease may overlap, which can ...

Pediatric mechanical circulatory support has evolved considerably in the past decade. Improvements in device design and availability have led to increased short-, medium-, and long-term support options for pediatric patients with heart failure. Most pediatric mechanical circulatory support is utilized as a bridge to transplant and as a bridge to ...

Since Herrick's description of the clinical picture of acute myocardial infarction exactly one century ago (1912), there have been three phases of therapy: Phase 1 (1912-1961, bed rest and 'expectant' treatment); Phase 2 (1961-1974, the coronary care unit); and Phase 3 (1975-present, myocardial reperfusion). We are now on the cusp ...

Aspirin is key to the treatment of acute myocardial infarction, particularly if stent implantation is considered. In patients with a history of hypersensitivity to aspirin, the optimal management of ST-segment elevation acute myocardial infarction is unclear. We suggest a strategy for addressing this problem by performing percutaneous coronary intervention with ...

Ventricular septal perforation represents a serious complication after acute myocardial infarction. This study aimed to evaluate the short-term and longterm outcomes of postinfarction ventricular septal perforation (VSP). We evaluated outcomes for VSP repair for 42 patients over 19 years. A retrospective analysis of clinical records, risk factors for hospital death, ...

Long-term endurance sports are associated with atrial remodeling and atrial arrhythmias. More importantly, high-level endurance training may promote right ventricular (RV) dysfunction and complex ventricular arrhythmias. We investigated the long-term consequences of marathon running on cardiac remodeling as a potential substrate for arrhythmias with a focus on the right heart. ...

Native renal infarction is uncommon in patients with atrial fibrillation (AF)-related thromboembolism. Graft infarction is also rare, with such cases mostly occurring in the main graft artery postoperatively. To date, there have been no studies of AF-related graft kidney infarction. We herein describe the first case of AF-related graft kidney ...

Patients with implantable cardioverter defibrillator lead insulation failures may present with oversensing and/or abnormal impedance. The Lead Integrity Alert (LIA) monitors right ventricular pace/sense leads using both continuous oversensing and daily impedance measurementd. Oversensing consists of isolated short R-R intervals and nonsustained runs of short R-R intervals. The LIA algorithm ...

Uncertainty remains regarding the benefits and risks of the technique of operating on a beating heart (off pump) for coronary artery bypass grafting (CABG) surgery versus on-pump CABG. Prior trials had few events and relatively short follow-up. There is a need for a large randomized, controlled trial with long-term follow-up ...

Hyperglycemia during admission for acute myocardial infarction (MI) is common and associated with poor outcomes. Prior studies employed two distinct approaches to improve outcomes in patients with acute MI-one focused on glucose control, and the other on provision of glucose, insulin, and potassium. However, despite multiple largescale studies, the benefits ...

The clinical course of an acute coronary syndrome can vary from relatively benign to potentially fatal. The biomarkers of myocardial necrosis relate to the amount of myocardial damage and are closely linked to a patient's prognosis. They are measured to help guide management decisions. Recent interest in myocardial neurohumoral mechanisms ...

Percutaneous ventricular assist devices are increasingly used today, allowing the scope of left ventricular support to move out of the operating room and into the interventional suite and cardiovascular care unit. This has given patients requiring short-term therapy an opportunity to undergo high-risk procedures and provide a failing left ventricular ...
