Early myocardial dysfunction following subarachnoid haemorrhage.
Like systolic dysfunction (SD), diastolic dysfunction (DD) has recently been proposed as a contributing factor in haemodynamic instability and in the genesis of pulmonary oedema, but its occurrence in subarachnoid haemorrhage (SAH) patients has not been described. Following aneurysmal SAH, three patients arrived at our institution with haemodynamic instability requiring vasoactive drugs and with pulmonary oedema. Transoesophageal echocardiographic study during aneurysm surgery documented mild to severe left ventricular SD and DD. Right ventricular SD and DD were also present. Documented biventricular systolic and diastolic myocardial dysfunctions may contribute to haemodynamic instability and pulmonary oedema following SAH due to intracranial aneurysmal rupture.
