Key result
Elective PCI is linked to ~3-point higher LVEF at 6 weeks in chronic stable angina.
Why the study?
The study aimed to determine the impact of PCI on myocardial function assessed by tissue Doppler echocardiography.
Does percutaneous coronary intervention improve myocardial function assessed by tissue Doppler imaging in patients with chronic stable angina and preserved left ventricular function?
Observational (n=50)
No

Absolute Event Rate: 58.7% vs 55.4%
p-value: p=<0.001
Elective PCI in patients with stable angina and preserved baseline EF significantly improves regional and global left ventricular myocardial function as detected by tissue Doppler imaging.
PCI associated with improved LVEF and tissue Doppler function at 6 weeks; hypothesis-generating and should not yet change practice in preserved-EF stable angina.

Mahmoud et al. (2020) conducted an observational in Chronic stable angina with preserved left ventricular function (n=50). Percutaneous coronary intervention (PCI) vs. Baseline (pre-PCI) was evaluated on Left ventricular ejection fraction (LVEF) at 6 weeks (p=<0.001). Percutaneous coronary intervention significantly improved left ventricular ejection fraction and tissue Doppler parameters of regional and global myocardial function at 6 weeks in patients with chronic stable angina.
