OBJECTIVES To compare the long term prognosis of patients having silent versus symptomatic ischaemia during dobutamine stress echocardiography (DSE). DESIGN Observational study. SETTING Tertiary referral centre. PATIENTS 931 patients who experienced stress induced myocardial ischaemia during DSE. RESULTS Silent ischaemia was present in 643 of 931 patients (69%). The number of dysfunctio...

The mechanism of ischaemia-induced bladder dysfunction is not entirely clear, but is thought to be a result of the ischaemia-related M-receptor hypersensitivity to acetylcholine. In addition to nerve injury, ischaemia may cause bladder detrusor fibrosis and urethra de-epithelialization. Bladder dysfunctions caused by bladder outlet obstruction (BOO) and aging detrusor were considered to be asso...

Ophthalmoscopic, fluorescein angiographic, electrophysiological, and morphological studies on 63 eyes of rhesus monkeys with acute transient experimental occlusion of the central artery of the retina (OCAR) showed that the retina suffered irreparable damage after ischaemia of 105 minutes but recovered well after ischaemia of 97-98 minutes. The tolerance time of the brain to acute transient isch...

A case is reported of a long segment stricture in a colonic oesophageal replacement with radiographic evidence to support the diagnosis of ischaemia. Ischaemia of the substitute organ following oesophageal resection is a well recognised, serious complication that usually results in anastomotic leakage. If the anastomosis heals primarily, late manifestations of ischaemia are rare.

The goal of anaesthetic management in patients with coronary artery disease (CAD) is the prevention of perioperative myocardial ischaemia. This approach is based on the assumption that sustained intraoperative ischaemia may precipitate postoperative myocardial infarction (MI) with its attendant complications. This presentation will review available information regarding perioperative ischaemia,...
