Methods
Eighty-five hospitalized patients with regional wall motion
abnormalities (RWMA) according to routine echocardiography in STEMI,
thirty patients with type 2 DM. All of them were underwent STE
associated with LDDSE (STE-LDDSE) prior to coronary angiography and
percutaneous coronary intervention (PCI). Every segment image was
acquired and evaluated by wall-motion analysis. The images of STE-LDDSE
were analyzed quantitatively for peak-systolic strain (S) and strain
rate (Sr), the short axis of radial strain (RS), radial strain rate
(RSr), circumferential strain (CS), circumferential strain rate (CSr)
and the long axis of longitudinal strain (LS), longitudinal strain rate
(LSr) by using the QLAB software. All patients underwent PCI within one
week after completing STE-LDDSE examination, and echocardiograms were
reviewed at 1, 3, and 6 months after surgery.
