Improved Regional Myocardial Diastolic Function Assessed by Strain Rate Imaging in Patients with Coronary Artery Disease Undergoing Percutaneous Coronary Intervention

Strain and Strain Rate Echocardiography and Coronary Artery Disease

“…40 In 27 patients, percutaneous coronary intervention increased the early diastolic SR in ischemic (but not nonischemic) segments and was associated with an increase in the early diastolic transmitral filling velocity; systolic SRs in ischemic and nonischemic segments were unchanged. 41 In 20 patients with severe angina ineligible for revascularization, an improvement in New York Heart Association angina class was associated with improvement in DSI (peak systolic strain), and systolic and diastolic myocardial and diastolic transmitral velocities with enhanced external counterpulsation. 42 …”

Emerging Clinical Role of Strain Imaging in Echocardiography

“…The peak strain rate in early diastole (E strain rate) has been used as an index of LV diastolic function and was found to be correlated with peak systolic strain rate in patients with ischaemic heart disease and improved with percutaneous revascularisation in ischaemic segments [18]. With strain rate imaging, diastole can be seen to comprise of a "stretch wave" in the LV myocardium, propagating from the base to the apex with the diastolic function characterised by both peak diastolic strain rate (peak E strain rate) and propagation velocity of this stretch wave.…”
