Bispectral index and suppression ratio after cardiac arrest: are they useful as bedside tools for rational treatment escalation plans?

Introduction And Objectives: Myocardial dysfunction contributes to early mortality (24-72 hours) among survivors of a cardiac arrest (CA). The benefits of mechanical support in refractory shock should be balanced against the patient's potential for neurological recovery. To date, these early treatment decisions have been taken based on limited information leading mainly to undertreatment.

Obstructive sleep apnea and coronary artery disease: from pathophysiology to clinical implications.

Coronary artery disease (CAD) and obstructive sleep apnea (OSA) are both complex and significant clinical problems. The pathophysiological mechanisms that link OSA with CAD are complex and can influence the broad spectrum of conditions caused by CAD, from subclinical atherosclerosis to myocardial infarction. OSA remains a significant clinical problem among patients with CAD, and evidence suggesting its role as a risk factor for CAD is growing.

Do patients with ST segment elevation myocardial infarction in Killip class I need intensive cardiac care after a successful primary percutaneous intervention?

Background And Objective: There are limited data regarding the need for intensive care or the appropriate length of hospital stay for patients with ST elevation acute myocardial infarction (STEMI). In order to optimize resources, we tried to determine the need of coronary care unit (CCU) admission for patients with STEMI who remained in Killip class I after a successful primary percutaneous coronary intervention (PPCI).

Methods: From August of 2006 till June of 2008, we analyzed data from all patients admitted in our CCU who met these criteria, a total of 278.

[Predictive factors of abnormal dynamic intraventricular gradient after valve replacement in severe aortic stenosis].

Introduction: Dynamic intraventricular gradients (DIG) after valve replacement in severe aortic stenosis have been reported, although the incidence of DIG and clinical signs are still poorly understood.Aim. To evaluate the incidence of DIG)and determine risk factors and associated morbimortality.
