Abstract:
Purpose: We aimed to evaluate the effects of preoperative pulmonary hypertension (PH)
on early and long term results in patients undergoing coronary bypass surgery and the
effects of coronary bypass surgery on PH.
Methods: Among 2325 patients who underwent elective isolated coronary artery bypass
surgery between March 2003 and March 2012, 287 patients with high preoperative pulmonary
arterial pressure (PAP) ≥30 mmHg were examined. Patients’ data were obtained
by retrospective examination of our clinic’s database. 69 patients who had complete
parameters included in the study.
Results: There was no increase in the New York Heart Association (NYHA) functional
classification 84% of cases. Preoperative and postoperative values of the mean ejection
fraction and mean PAP of patients was respectively 45.28 ± 9.67 (25–65), 46.03 ±12.4
(20–65) (p = 0.447), 36.67 ± 6.81 (30–60) mmHg, 37.81 ± 10.07 (20–70) mmHg (p = 0.378).
The late mortality of cases was 5.79%. In our study, during 33.9 ± 17 (9–100) months follow
up period, life expectancy was calculated as 94.7 months.
Conclusion: Preoperative evaluation of these patients for appropriate medical treatment
at peroperative and postoperative period, coronary bypass can be performed with low
morbidity and mortality rates. In the late period after surgical revascularization PH
showed no significant change and had no adverse effect on quality of life.
