Background: The role of left ventricular global longitudinal strain (LVGLS) in coronary artery bypass grafting (CABG) and outcomes such as low cardiac output syndrome (LCOS) is not well established. The authors investigated the relationship between LVGLS before and after induction of anesthesia, their differences, and their relationship with LCOS and other outcomes.
Methodology: A prospective observational study was conducted in a public/private hospital with 50 adult patients scheduled for on-pump CABG with normal left ventricular ejection fraction (LVEF).
Levosimendan for sepsis-induced myocardial dysfunction: friend or foe?

Department of Critical Care Medicine, Chongqing University Three Gorges Hospital, Wanzhou, Chongqing, China.
Sepsis-induced myocardial dysfunction (SIMD) involves reversible myocardial dysfunction. The use of inotropes can restore adequate cardiac output and tissue perfusion, but conventional inotropes, such as dobutamine and adrenaline, have limited efficacy in such situations. Levosimendan is a novel inotrope that acts in a catecholamine-independent manner.

Unlabelled: Stress-induced cardiomyopathy is a condition of acute myocardial suppression following an abrupt release of endogenous catecholamines after emotional or physical stress. The exact mechanism is unknown but there are reports of a similar clinical presentation after injection of exogenous catecholamines such as beta agonists. We report a rare type of stress-induced cardiomyopathy following injection of dobutamine during a diagnostic stress echocardiography.
