Abstract:
Objective To evaluate the effect of preoperative pulmonary artery pressure on perioperative prognosis of the recipients with end-stage heart failure undergoing heart transplantation. Methods Clinical data of 105 recipients receiving heart transplantation were retrospectively analyzed. The mean pulmonary artery pressure (mPAP) was used as the diagnostic criterion. The optimal cut-off value of mPAP for predicting perioperative prognosis of heart transplant recipients was determined. According to the optimal cut-off value of mPAP, all recipients were divided into the low mPAP group (n=66) and high mPAP group (n=39). Intraoperative indexes (cardiopulmonary bypass time, aortic occlusion time, assisted circulation time and cold ischemia time of donor heart) and postoperative indexes [intra-aortic balloon pump (IABP) support rate, IABP support time, extracorporeal membrane oxygenation (ECMO) support rate, ECMO support time, mechanical ventilation time, length of ICU stay, incidence of moderate and severe tricuspid regurgitation and perioperative mortality rate] were compared between the low and high mPAP groups. The prognosis of the two groups was compared. Results The optimal cut-off value of mPAP in predicting clinical prognosis of heart transplant recipients was 30.5 mmHg. In the high mPAP group, the ECMO support rate and perioperative mortality rate were higher than those in the low mPAP group (both P < 0.05). No significant differences were observed in the cardiopulmonary bypass time, aortic occlusion time, assisted circulation time, cold ischemia time of donor heart, IABP support rate, IABP support time, ECMO support time, mechanical ventilation time, length of ICU stay and incidence of moderate and severe tricuspid regurgitation between two groups (all P > 0.05). No significant differences were noted in the 1-, 2-, 3- and 4- survival rates between two groups (all P > 0.05). Conclusions Preoperative mPAP in patients with end-stage heart failure is intimately correlated with perioperative prognosis of heart transplant recipients. The optimal cut-off value of mPAP in predicting perioperative prognosis of heart transplant recipients is 30.5 mmHg. In the high mPAP group, perioperative ECMO support rate and perioperative mortality rate are high, which do not affect the medium and long-term prognosis of the recipients undergoing heart transplantation.
