Intraoperative hypotension in noncardiac surgery patients with chronic beta-blocker therapy: A matched cohort analysis.

Study Objective: To explore the incidence of intraoperative hypotension in patients with chronic beta-blocker therapy, expressed as time spent, area and time-weighted average under predefined mean arterial pressure thresholds.

Design: Retrospective analysis of a prospective observational cohort registry.

Setting: Patients ≥60 years undergoing intermediate- to high-risk noncardiac surgery with routine postoperative troponin measurements on the first three days after surgery.

Immediate postoperative high-sensitivity troponin T concentrations and long-term patient-reported health-related quality of life: A prospective cohort study.

Background: Myocardial injury after noncardiac surgery is associated with mortality and major adverse postoperative cardiovascular events. The effect of postoperative troponin concentrations on patient-reported health-related quality of life (HRQoL) is unknown.

Objective: The study examined the association between immediate postoperative troponin concentrations and self-reported HRQoL 1 year after surgery.

Postoperative Hypotension after Noncardiac Surgery and the Association with Myocardial Injury.

Background: Intraoperative hypotension has been associated with postoperative morbidity and early mortality. Postoperative hypotension, however, has been less studied. This study examines postoperative hypotension, hypothesizing that both the degree of hypotension severity and longer durations would be associated with myocardial injury.

Preoperative coronary angiography in vascular surgery patients with asymptomatic elevated high-sensitivity troponin T: a case series.

This case series presents 10 patients undergoing vascular surgery with asymptomatic elevated high-sensitivity troponin T concentrations, measured at outpatient clinic before surgery. Patients were included in the RAVE (Rotterdam Antiplatelet therapy in Vascular patiEnts) pilot study. All included patients underwent coronary angiography before surgery to identify significant obstructive coronary artery disease.

Comparison of Genome Sequences from Strains Isolated from Symptomatic and Asymptomatic Patients.

is a common cause of respiratory tract infections (RTIs) in children. We recently demonstrated that this bacterium can be carried asymptomatically in the respiratory tract of children. To identify potential genetic differences between strains that are carried asymptomatically and those that cause symptomatic infections, we performed whole-genome sequence analysis of 20 strains.
