Impact of OSA on cardiovascular events after coronary artery bypass surgery.

Background: The impact of OSA on new cardiovascular events in patients undergoing coronary artery bypass graft (CABG) surgery is poorly explored.

Methods: Consecutive patients referred for CABG underwent clinical evaluation and standard polysomnography in the preoperative period. CABG surgery data, including percentage of off-pump and on-pump CABG, number of grafts, and intraoperative complications, were collected.

OSA and depression are common and independently associated with refractory angina in patients with coronary artery disease.

Objective: Refractory angina is a severe form of coronary artery disease (CAD) characterized by persistent angina despite optimal medical therapy. OSA and depression are common in patients with stable CAD and may contribute to a poor prognosis. We hypothesized that OSA and depression are more common and more severe in patients with refractory angina than in patients with stable CAD.

[Evaluation of practices for the prevention and control of bloodstream infections in a government hospital].

The aim of this study was to observe clinical procedures in order to evaluate the practices used for the control and prevention of bloodstream infections associated with short-term central venous catheters (BSI-ACVC). The study data came from 5877 assessments distributed among selected practices. The results revealed the following adherence rates among the practices selected: 91.

Obstructive sleep apnea is common among patients referred for coronary artery bypass grafting and can be diagnosed by portable monitoring.

Background: Obstructive sleep apnea (OSA) is common among patients with coronary artery disease. However, OSA remains largely under recognized. The lack of clinical suspicion and difficulties to access full polysomnography (PSG) are limiting factors.
