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.

The alterations of LV mechanics responses to a 3-min low dose exercise stress echocardiography following time.
Tidsramme: detected at the in-hospital and the day 7, 14, 30, 60, and 180 after discharge.
|
The STE was performed at rest, during exercise and recovery to compare the changes of LV machines following discharge.
The standardized exercise test was conducted by 50-W semirecumbent cycling (Cardiac Stress Table w/Angio) for 3 min.
Stress echocardiograph images were acquired at the third minute of cycling to ensure that subjects had reached a steady-state HR.

The graded exercise test (GXT) was performed with a cycle ergometer at the day 30 and 180 after discharge.

Minute ventilation (V˙ E), V˙ O2, and CO2 production (V˙ CO2) were measured breath-by-breath using a computer-based system (MasterScreen CPX; Cardinal Health Germany).
