Why the study?
The effect of PCI on longitudinal and circumferential systolic and diastolic function in patients with chronic stable angina has shown controversial results.
Does percutaneous coronary intervention (PCI) improve myocardial systolic and diastolic function assessed by Tissue Doppler imaging (TDI) in patients with stable coronary artery disease?
Does percutaneous coronary intervention (PCI) improve myocardial systolic and diastolic function assessed by Tissue Doppler imaging (TDI) in patients with stable coronary artery disease?
Tissue Doppler detects early post-PCI systolic gains missed by EF; leaves open whether this improves outcomes in stable angina.
Background: Patients with stable coronary artery disease may have subtle derangements in their cardiac function before evident changes in conventional echocardiographyderived ejection fraction (EF). These derangements manifest firstly in the longitudinal before circumferential LV function. The effect of PCI on longitudinal and circumferential systolic and diastolic function of the ventricle in patients with chronic stable angina has shown controversial results. In the current study, we tried to evaluate the impact of percutaneous coronary intervention (PCI) on myocardial systolic and diastolic function assessed by different non-invasive indices as EF, Myocardial Performance Index (MPI) and longitudinal myocardial function assessed by Tissue Doppler imaging (TDI) in patients with stable coronary artery disease.
