Newly developed T-wave inversion with cardiac wall-motion abnormality predominantly occurs in middle-aged or elderly women after noncardiac surgery.
The study was done to determine the characteristics and prevalence of myocardial ischemia with inverted T waves after noncardiac surgery. ⋯ Newly developed giant negative T waves with QT prolongation in the ECG may indicate myocardial stunning, but do not in themselves imply a poor prognosis. The marked preponderance of middle-aged and elderly women with this type of myocardial ischemia remains to be explained.

Randomized Controlled Trial Clinical TrialHemodynamic and catecholamine responses during tracheal intubation using a lightwand device (Trachlight) in elderly patients with hypertension.
Tracheal intubation using a lightwand device (Trachlight) should minimize hemodynamic change by avoiding direct-vision laryngoscopy. We evaluated hemodynamic and catecholamine responses during tracheal intubation using a Trachlight in elderly patients with hypertension. ⋯ A lightwand has no advantage over a laryngoscope in terms of hemodynamic and plasma catecholamine responses to tracheal intubation in elderly patients with hypertension, despite a shorter intubation time.
