2021年3月26日 更新者：Li-Wei Chou、China Medical University Hospital
Using Exercise Echocardiography to Investigate the Effects of Different Exercise Trainings on Left Ventricular Mechanics in Patients With Coronary Artery Disease: a Speckle-tracking Echocardiography
Recovering blood flow to a coronary stenosis may improve left ventricular (LV) function in patients with coronary artery disease (CAD).
However, the reported data about evaluation of LV function post-percutaneous coronary intervention (PCI) in CAD was limited.
The aim of this study was to compare the LV function measured by 3 min low dose exercise stress echocardiography (ESE) combined 2D speckle tracking echocardiography (STE) in patients with CAD underwent PCI, and to identify factors affecting the change of LV function.
Patients with CAD who underwent acute PCI were enrolled.
調査の概要
詳細な説明
The assessment of temporal changes in systolic and diastolic regional left ventricle function by 2D-STE after successful reperfusion therapy of acute myocardial infarction (AMI).The estimated total number of participants is 90 patients with AMI and treated with successful percutaneous coronary intervention were included in this study.
The echocardiographic measurements were performed in all patients within in-hotpital after PCI procedure, and then followed up at 7, 14, 30, 60 and 180 days after discharge.
Recovery of regional systolic and diastolic myocardial function after acute myocardial infarction evaluated by ESE-STE.

STEMI
ST-segment elevation myocardial infarction (STEMI) is defined by symptoms of myocardial ischemia accompanied by a persistent elevation of the ST segment on the electrocardiogram (ECG) and the subsequent release of biomarkers of myocardial necrosis.
|
Stress echocardiography test.
The standardized exercise test was conducted by 50-W semi-recumbent cycling for 3 min.
Stress echocardiograph images were acquired at the third minute of cycling to ensure that subjects had reached a steady-state HR.
|
|
NSTEMI
If there is elevation of the blood markers suggesting heart damage, but no ST elevation seen on the EKG tracing, this is known as a non ST-elevation myocardial infarction (NSTEMI).
|
Stress echocardiography test.
The standardized exercise test was conducted by 50-W semi-recumbent cycling for 3 min.
Stress echocardiograph images were acquired at the third minute of cycling to ensure that subjects had reached a steady-state HR.
