Key result
Coronary artery bypass graft surgery improved left ventricular diastolic function but significantly decreased right ventricular early diastolic velocity from 9.8 to 7.7 cm/s at 5 days (p=0.005).

RV diastolic velocity decline post-CABG warrants monitoring but should not yet change practice; leaves open long-term impact and outcome associations.

Does CABG surgery affect myocardial function as assessed by tissue Doppler echocardiography in patients with preserved preoperative systolic function?
Absolute Event Rate: 7.7% vs 9.8%
p-value: p=0.005
In patients with preserved LV systolic function, CABG improves LV diastolic function but impairs RV function, regardless of whether on-pump or off-pump techniques are used.
Diller et al. (2008) conducted a cohort in Preserved preoperative systolic function undergoing CABG (n=32). Coronary artery bypass graft (CABG) surgery vs. Preoperative baseline was evaluated on Right ventricular peak early diastolic velocity (E') at 5 days (p=0.005). Coronary artery bypass graft surgery improved left ventricular diastolic function but significantly decreased right ventricular early diastolic velocity from 9.8 to 7.7 cm/s at 5 days (p=0.005).
