Liver dysfunction as an important predicting risk factor in patients undergoing cardiac surgery: a systematic review and meta-analysis.

Liver function is not considered as a risk factor by current risk scores, such as EUROSCORE II or STS-Score for cardiac surgery. The aim of this study was to review the role of liver dysfunction, classified by the Child-Turcotte-Pugh classification or model for end-stage liver disease scores, as a risk factor for mortality and morbidity of patients following cardiac surgery. The Pubmed referencing library was searched.

Prognostic factors in pulmonary hypertension.

Background And Objectives: Pulmonary hypertension is a hemodynamic and pathophysiological condition defined as an increase in mean pulmonary pressure more than or equal to 25 mm Hg. Evaluation of pulmonary hypertension severity and prognosis plays a central role in the management of these patients, between diagnosis and therapeutic decision making. The aim of our study was to identify the adverse prognostic factors in patients with pulmonary hypertension and their impact on mortality, quality of life, need for hospitalization and complications during hospitalization.

Echocardiographic predictors of adverse short-term outcomes after heart surgery in patients with mitral regurgitation and pulmonary hypertension.

Background: Pulmonary hypertension (PH) is a frequent occurrence and a negative prognostic indicator in patients with mitral regurgitation. Preoperative PH causes higher early and late mortality rates after heart surgery, adverse cardiac events, and postoperative systolic dysfunction in the left ventricle (LV).

Methods: The research consisted of a retrospective study of a group of 171 consecutive patients with mitral regurgitation and preoperative PH who had undergone mitral valve surgery between January 2008 and October 2011.
