Introduction

Classified classically as dilative, hypertrophic, or restrictive on echocardiographic findings this may not be so helpful in determining aetiology. The commonest cause is ischaemic, but the interactions with genes, infections, toxins and hypertension can make these causes underestimated. Chronic adenergic stimulation (catecholamines) is also a known cause.
