Non-traumatic out of hospital cardiac arrest (OOHCA) is one of the leading causes of death in western world. Acute coronary syndrome (ACS) is the most common aetiology of OOHCA with a culprit artery lesion identified on invasive angiography. However, 1/3rd of patients with OOHCA have unobstructed coronaries on angiography. Non-invasive ...

A precise understanding and quantification of myocardial contraction is essential for optimising peri-operative care in high risk CABG surgery. Conventional approach has been focused on the magnitude of myocardial contraction, while its time course has received little clinical attention. This study was aimed to characterise the changes in both physiological ...

Type-2 diabetes mellitus (T2DM) is risk factor for developing cardiac dysfunction and heart failure. The plasma concentration of amino-terminal pro-brain natriuretic peptide (NT-proBNP) could be a simple tool for screening for cardiac dysfunction amongst older patients with T2DM. Patients receiving treatment for T2DM for at least 12 months, aged >40 ...

Left ventricular noncompaction (LVNC) is characterised by prominent ventricular myocardial trabeculations, composed of sheets of cardiomyocytes. They form early during cardiogenesis but their development is complex. Measuring trabecular complexity in animal models of cardiac disease is important as abnormal trabecular patterns are increasingly been recognised to coexist with several other ...

Increased H2S availability, through use of H2S donors, or in mice overexpressing the H2S synthetic enzyme cystathionine gamma-lyase (CSE), reduces injury associated with myocardial ischemia (MI) and ischemia-reperfusion. The mitochondrial enzyme thiosulfate sulfurtransferase (TST) has a putative role in removal of H2S and inhibition may provide an alternative means of ...

Hypertension and ageing are the commonest risk factors for atrial fibrillation (AF) and a significant cause of ventricular dysfunction, which may lead to arrhythmia. Putative factors in the remodelled substrate are connexin 43 (Cx43), the most abundant cardiac gap junction and fibrosis. The spontaneous hypertensive rat (SHR) has been demonstrated ...

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited disorder that causes sudden death and right ventricular heart failure in young athletes. Loss-of-function mutations in desmosomal proteins including plakoglobin deficiency are linked with ARVC and ventricular arrhythmias in trained mice. Chronic intensive endurance training increases susceptibility to atrial arrhythmias in rats. ...

Knowledge of cardiac arrest (CA) causes other than coronary artery disease is derived predominantly from post-mortem studies, identifying hypertrophic cardiomyopathy (HCM) as the commonest diagnosis. Management of CA survivors mandates definite attempts towards diagnosis, particularly as the cause may be inherited with implications for family screening. Our approach to non-ischaemic ...

In patients with cardiac sarcoidosis, the sarcoid granulomas usually involve the myocardium or endocardium. The disease typically presents as heart failure with ventricular arrhythmias, conduction disturbances, or both. Constrictive pericarditis has rarely been described in patients with sarcoidosis: we found only 2 reports of this association. We report the case ...

We recently developed a clinically relevant mini-swine model of heart failure with preserved ejection fraction (HFpEF), in which diastolic dysfunction was associated with increased mitochondrial permeability transition (MPT). Early diastolic function is ATP and Ca(2+)-dependent, thus, we hypothesized chronic low doses of cyclosporine (CsA) would preserve mitochondrial function via inhibition ...
