Key result
Multivariate regression analysis demonstrated that specific preoperative and operative factors, such as left ventricular muscle mass index and extracorporeal circulation time, significantly predicted the severity of postoperative low cardiac output syndrome.
Observational (n=145)

Preoperative and operative variables, including left ventricular muscle mass index and ergometer exercise testing, can quantitatively predict the risk of postoperative low cardiac output syndrome after valve replacement.

May aid preoperative risk stratification in valve surgery; leaves open prospective validation before clinical use.
Sato et al. (1993) conducted an observational in Valvular heart disease requiring valve replacement (n=145). Valve replacement surgery was evaluated on Postoperative low cardiac output syndrome (LOS) score. Multivariate regression analysis demonstrated that specific preoperative and operative factors, such as left ventricular muscle mass index and extracorporeal circulation time, significantly predicted the severity of postoperative low cardiac output syndrome.
