Key result
A 2-3 month cardiac rehabilitation program significantly decreased left ventricular end-diastolic pressure from 10.5 to 9.1 mmHg and pulmonary artery systolic pressure from 30.3 to 27.3 mmHg in patients after CABG surgery.
Why the study?
Although cardiac rehabilitation improves risk factors, life expectancy, and quality of life in ischemic heart disease, its effects on pulmonary artery systolic pressure and left ventricular end-diastolic pressure required evaluation.
Does a cardiac rehabilitation program improve pulmonary artery systolic pressure and left ventricular end-diastolic pressure in patients with ischemic heart disease after CABG surgery?
Does a cardiac rehabilitation program improve pulmonary artery systolic pressure and left ventricular end-diastolic pressure in patients with ischemic heart disease after CABG surgery?

Cardiac rehabilitation after CABG surgery significantly improves left ventricular end-diastolic pressure and ejection fraction.
Background: Cardiac rehabilitation program (CRP) is a useful method of modifying cardiovascular risk factors, improving life expectancy and quality of life in patients with ischemic heart disease (IHD). The present study was conducted to evaluate the effects of cardiac rehabilitation on the pulmonary artery systolic pressure (PASP) and left ventricular end-diastolic pressure (LVEDP). Methods: This Quasi-experimental study with pretest-posttest design was conducted on 80 patients with IHD who had participated in CRP after undergoing coronary artery bypass graft (CABG) surgery. Echocardiography was performed before the beginning of CRP (the 1st session) and at the end of the rehabilitation sessions, and ventricular function indices (ejection fraction), PASP (using the tricuspid regurgitation velocity), and LVEDP (using Nagueh formula: 1.24�E/e�+1.9) were measured. Results: Ejection fraction (EF) was changed from 49.3 ± 7.8 before rehabilitation to 50.7 ± 7.4 after rehabilitation, which was a statistically significant difference (P=0.003). The pulmonary artery systolic pressure altered from 30.3 ± 8.4 before rehabilitation to 27.3 ± 6.6 after rehabilitation. The left ventricular end-diastolic pressure (LVEDP) changed from 10.5 ± 3.7 before rehabilitation to 9.1 ± 2.9 after rehabilitation, which was a statistically significant difference (P=0.000). Conclusion: According to the results, LVEDP and PASP in patients with IHD who underwent CABGs decreased after cardiac rehabilitation. © 2020, Kerman University of Medical Sciences.

Moazenzadeh et al. (2020) studied Ischemic heart disease after coronary artery bypass graft (CABG) surgery (n=80). Cardiac rehabilitation program vs. Pre-rehabilitation baseline was evaluated on Left ventricular end-diastolic pressure (LVEDP) (p=0.000). A 2-3 month cardiac rehabilitation program significantly decreased left ventricular end-diastolic pressure from 10.5 to 9.1 mmHg and pulmonary artery systolic pressure from 30.3 to 27.3 mmHg in patients after CABG surgery.
