Mechanisms of angina

摘要

Angina is traditionally thought to be "ischaemic" in origin with increasing demands for blood in the myocardium giving rise to visceral pain. Prolonged ischaemia leads to myocardial infarction. The prognosis for each condition may depend on their varying aetiologies. Recent studies demonstrate aberrant myocardial reinnervation in ventricular arrhythmias, cardiomyopathies and after myocardial infarction; in some circumstances periarteriolar reinnervation takes place.
