Abstract: The long QT syndrome (LQTS) is caused by delayed cardiac repolarisation and may be associated with ventricular arrhythmias (torsades de pointes) and sudden death. The congenital LQTS is caused by mutations in any one of many genes coding for ion channels responsible for cardiac repolarisation. The acquired LQTS is much more common and may be associated with various metabolic conditions, acquired heart disease or drugs. The apparent idiosyncratic development of QT prolongation under these circumstances may well expose a much larger population with silent genetic mutations. Attention has focused on the growing list of drugs implicated in the causation of the syndrome and this has led to the withdrawal of some drugs and new guidelines for the pre-clinical and clinical testing of new drugs. Clinicians should be aware of the drugs that may cause this syndrome and its potentially fatal arrhythmias, as well as the conditions that make patients more vulnerable. Patients should be made aware of the risk of drug interactions and precautions when prescribed these drugs. Adverse drug effects suggestive of cardiac arrhythmias should be reported to drug regulatory authorities The LQTS has vastly expanded our knowledge of the molecular and genetic basis of cardiac repolarisation and arrhythmogenesis and its clinical significance is increasing.

Abstract: The mortality, morbidity and economic burden imposed by congestive heart failure are considerable. Despite a prevalence and prognosis comparable to the more commonly encountered cancers like breast and lung cancer, there has been relatively less emphasis in the western world on the screening, diagnosis and treatment of heart failure, at least until recently. This may be partly attributed to the fact that the complex pathophysiology of heart failure was ill understood and the heterogeneity of the syndrome not recognised, so that even among specialist cardiologists it was considered pretty much an irreversible condition amenable only to palliative therapy. However, our understanding of heart failure has grown significantly in the past decade. From the early days when all dysfunctional myocardium was considered necrosed, and revascularisation often dismissed on this basis, we have now progressed to the understanding that dysfunctional myocardium is a heterogeneous entity comprising necrotic, stunned, hibernating and myopathic myocardium, and that the therapeutic objectives in each of these categories is specific and should be addressed individually. In this article we briefly review the pathophysiology, and diagnostic and therapeutic implications of reversible ischaemic left ventricular dysfunction.
