[Prospective study of early and late morbidity and mortality in the abdominal aortic aneurysm surgical repair].

Objective: To prospectively assess early and late morbidity and mortality of patients undergoing elective surgical repair of abdominal infrarenal aortic aneurysms and to determine the independent predictors of cardiac events.

Methods: For 6 consecutive years, this study analyzed 130 patients, who underwent routine standardized preoperative assessment always with the same clinical, surgical, and anesthesia teams.

Results: In-hospital mortality was 3.

Acute reduction of ventricular volume decreases QT interval dispersion in elderly subjects with and without heart failure.

To evaluate the effects of acute reduction in ventricular volume (VV) on QT interval dispersion (QTd), 14 men with heart failure (HF; 74.5 +/- 2 yr of age) and 11 healthy male control subjects (68 +/- 2 yr of age) were studied. For 15 min, lower body negative pressure (LBNP) was applied at -15 and -40 mmHg to reduce venous return.
