Persistent (current) in the face of adversity ... a new class of cardiac anti-ischaemic compounds on the horizon?

Abstract

Although a persistent component of the sodium current (INaP) was described in cardiac tissue about three decades ago, its physiological role and potential as a therapeutic target was not immediately apparent. Subsequent demonstrations that INaP is enhanced by hypoxia and ischaemia, and that Na+ influx via INaP may contribute to cellular damage, diastolic dysfunction and arrhythmias during ischaemia and reperfusion, raised interest in INaP as a target for anti-ischaemic drugs. Several agents have now been developed to clinical stages, which have INaP block as either their main action, or as a useful co-effect. In this issue of the British Journal of Pharmacology, Vacher et al. report the anti-ischaemic actions of F15845, which appears to exhibit the most selective block of INaP yet described. Its efficacy in animal models of angina raises the prospect of new, specific, INaP blockers that may represent a largely unexploited opportunity for a new class of anti-ischaemic compounds.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
