Abstract

Objective. To determine the effect of increased pulmonary artery pressure on the risk of organ dysfunction in patients operated on heart valves.

Material and methods. The study is single-center, retrospective, randomized. A comparative analysis of the frequency and structure of organ dysfunction in the early postoperative period in 3945 patients with heart valves diseases, divided into 3 groups depending on the presence of high pulmonary artery pressure (PAP) and its value, according to the criteria of the risk scale of cardiac surgery EuroSCORE II: the group of normal PAP (systolic PAP (PAPsyst) not more than 31 mm Hg) – 2655 patients, the group of moderate PAP (PAPsyst 31–55 mm Hg) – 849 patients and the group of high PAP (PAPsyst over 55 mm Hg) – 441 patients.

Results. Increased PAP was a risk factor for early postoperative acute heart failure (odds ratio (OR) 1.9; 95% confidence interval (CI) 1.61–2.19, p<0.05), decreased contractility of the left ventricular myocardium (left ventricular ejection fraction less than 50%) (OR 2.0; 95% CI 1.79–2.29, p<0.05), impaired oxygenating lung function (OR 1.2; 95% CI 1.06–1.34, p<0.05), including acute respiratory distress syndrome (ARDS) (OR 4.0; 95% CI 3.39–4.61, p<0.05) and multiple organ failure (OR 1.8; 95% CI 1.47–2.13, p<0.05). The risk factor for hepatic dysfunction was only high PAP (OR 1.4; 95% CI 1.09–1.71, p<0.05). The presence of elevated PAP doubled postoperative mortality (OR 2.1; 95% CI 1.67–2.53, p<0.05).

Conclusion. Increased PAP is a risk factor for acute heart failure, impaired oxygenating lung function, ARDS, multiple organ failure in the early postoperative period and increased postoperative mortality in patients with heart valves diseases.
