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 ...

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. ...

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 ...

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 ...

Supraventricular tachyarrhythmia (including atrial fibrillation), hypertension and tachycardia in the perioperative setting, and acute ischaemic heart disease are generally agreed to require rapid attention and treatment. Prolonged tachyarrhythmia or hypertension can result in significant morbidity, such as cerebrovascular events, myocardial infarction and other end-organ damage. This article reviews the clinical ...

Abrupt changes in heart rate, particularly short-long-short sequences in the ventricular cycle length (CL), might precede initiation of ventricular tachycardia/fibrillation (VT/VF). These changes may be facilitated or caused by pacing activity in patients with pacemakers or implantable-cardioverter defibrillators (ICDs). We describe a patient with two episodes of acquired VT precipitated ...

Acute myocardial infarction (MI) during pregnancy is rare and MI due to Prinzmetal's angina is much rarer. We present a 35-year-old, obese, multigravida, and pre-eclamptic woman, who developed acute anterior wall MI at the 30th week of gestation. On coronary angiography, the second obtuse marginal branch was totally occluded and ...

Until recently acute inflammatory peri-myocardial syndromes have been associated with global rather regional left ventricular (LV) dysfunction. Recent advances in cardiac imaging with echocardiographic techniques and magnetic resonance imaging (MRI) permit comprehensive evaluation of global and regional LV function. Our study was aimed to assess regional LV function in 100 ...
