Background: Thyrotoxicosis influences cardiovascular hemodynamics and can induce coronary vasospasm. Patients with thyrotoxicosis-induced acute myocardial infarction (AMI) are unusual and almost all reported cases have been associated with Graves' disease. Patients with painless thyroiditis show a thyrotoxic phase during the early stages. Here we describe a very rare case of ...

Salt-loading is an accelerator of hypertensive left ventricular (LV) remodeling. The relationship between salt-loading doses and the time window in which a transition from compensated to decompensated LV hypertrophy occurs in spontaneously hypertensive rats (SHR) is unclear. Eight-week-old male SHR and Wistar Kyoto rats (WKY) were randomized to receive normal ...

Left ventricular non-compaction (LVNC) is a cardiomyopathy considered to be caused by arrest of normal embryogenesis of the endocardium and myocardium. Echocardiography has been the preferred diagnostic procedure; however, the correct diagnosis is often missed or delayed due to the lack of knowledge about this uncommon disease and its similarities ...

During cardiac remodelling, the heart generates higher levels of reactive species; yet an intermediate 'compensatory' stage of hypertrophy is associated with a greater ability to withstand oxidative stress. The mechanisms underlying this protected myocardial phenotype are poorly understood. We examined how a cellular model of hypertrophy deals with electrophilic insults, ...

Sulfur dioxide has recently been found to be produced endogenously in the cardiovascular system and have important positive biological effects. However, it is unknown whether sulfur dioxide preconditioning has a protective effect on rat myocardial ischemia/reperfusion (I/R) injury and whether this process involves endoplasmic reticulum stress (ERS). In this study, ...

Antioxidant enzymatic pathways form a critical network that detoxifies ROS in response to myocardial stress or injury. Genetic alteration of the expression levels of individual enzymes has yielded mixed results with regard to attenuating in vivo myocardial ischemia-reperfusion injury, an extreme oxidative stress. We hypothesized that overexpression of an antioxidant ...

A beat-to-beat variation in the cardiac action potential duration is a phenomenon known as alternans. Alternans has been linked to ventricular fibrillation, and thus the ability to predict the onset of alternans could be clinically beneficial. Theoretically, it has been proposed that the slope of a restitution curve, which relates ...

Adenoviral-mediated (AdV-T2) overexpression of TIMP-2 would blunt ventricular remodeling and improve survival in a murine model of chronic ischemic injury. Male mice (n = 124) aged 10-14 weeks underwent either (1) left coronary artery ligation to induce myocardial infarction (MI group, n = 36), (2) myocardial injection of 6 × ...

Ventricular preexcitation, a feature of Wolff-Parkinson-White syndrome, is caused by accessory myocardial pathways that bypass the annulus fibrosus. This condition increases the risk of atrioventricular tachycardia and, in the presence of atrial fibrillation, sudden death. The developmental mechanisms underlying accessory pathway formation are poorly understood but are thought to primarily ...

OBJECTIVES:: Arrhythmia is of concern after cardiac stem cell transplantation in repairing infarcted myocardium. However, whether transplantation improved the ventricular fibrillation threshold and whether severe malignant ventricular arrhythmia is induced in the myocardial infarction model are still unclear. We sought to investigate the electrophysiologic characteristics and ventricular fibrillation threshold in ...

Myosin heavy chain (MHC) isoforms are principal determinants of work capacity in mammalian ventricular myocardium. The ventricles of large mammals including humans normally express ∼10% α-MHC on a predominantly β-MHC background, while in failing human ventricles α-MHC is virtually eliminated, suggesting that low-level α-MHC expression in normal myocardium can accelerate ...

A 74-year-old man without history of ventricular arrhythmias underwent coronary bypass surgery for 3-vessel disease. On the 4th postoperative day, he developed ventricular fibrillation (VF). His monitored ECG showed no elevation of the ST-segment and no prolongation of QT interval, but evolving J waves prior to VF were shown. These ...

Acute myocardial infarction is a life-threatening condition. Coronary dissection after blunt chest trauma is a rare event. Chest pain is a common symptom after chest trauma, which may relate to chest contusion without cardiac injury or myocardial infarction. Differentiation between minor cardiac contusion and significant cardiac injury is difficult and ...

Background/Aims: Flow restoration to ischemic myocardium reduces infarct size (IS), but it also promotes reperfusion injury. A burst of reactive oxygen species (ROS) and/or NHE-1 reactivation were proposed to explain this injury. Our study was aimed to shed light on this unresolved issue. Methods: Regional infarction (40 min-ischemia/2 hs-reperfusion) was ...

Echocardiography and magnetic resonance imaging revealed biventricular non-compaction cardiomyopathy with ventricular (VSD) and atrial (ASD) septal defects in an unconscious, 23-year-old hypoxemic man. Doppler echocardiography showed a left-to-right shunt across the VSD and a right-to-left shunt across the ASD. Cardiac catheterization revealed elevated right atrial pressure, although pulmonary pressure was ...

The aim of this experiment was to establish whether verapamil, nicardipine, and nitroglycerin have (1) infarct size-limiting effects and (2) antiarrhythmic effects in in vivo rabbit hearts during ischemia/reperfusion. Rabbits received regional ischemia by 30 min of left anterior descending coronary artery occlusion followed by 3 hours of reperfusion under ketamine ...

A 32 year old man presented to casualty on three occasions in the space of four days, with intermittent, worsening abdominal pain. These symptoms imitated other commoner causes of acute abdomen and the site of onset changed, both factors delaying diagnosis. In due course, computer tomography imaging established findings indicative ...

Left ventricular reconstruction is advocated as a surgical option for patients with severe congestive heart failure. Despite initial enthusiasm for this procedure, reports of long-term results are sparse. Herein, we describe a particularly gratifying case of left ventricular reconstruction in a 43-year-old man, who continues to have excellent left ventricular ...

Ischemia of the myocardium can lead to reversible or irreversible injury depending on the severity and duration of the preceding ischemia. Here we compared sevoflurane and isoflurane with particular reference to their hemodynamic effects and ability to modify the effects of acute severe myocardial ischemia and reperfusion on ventricular arrhythmias ...
