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.
|
Other: exercise stress echocardiography
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).
|
Other: exercise stress echocardiography
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. [ Time Frame: 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.
- Cardiopulmonary fitness [ Time Frame: detected at the day 30, 60, and 180 after discharge. ]The graded exercise test (GXT) was performed with a cycle ergometer at the day 30 and 180 after discharge. The GXT comprised of unloaded pedaling for 2 min followed by a continuous increase in work rate (20-30 W) every 3 min until exhaustion (i.e., V˙ O2max). 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).
- The brain-type natriuretic peptide (BNP) levels [ Time Frame: detected at the detected at the in-hospital and the day 7, 14, 30, 60, and 180 after discharge.ay 30, 60, and 180 after discharge. ]BNP levels (picograms/milliliter) will be analysed from blood samples taken by a registered phlebotomist.
- The high-sensitivity CRP (hsCRP) levels [ Time Frame: detected at the detected at the in-hospital and the day 7, 14, 30, 60, and 180 after discharge.ay 30, 60, and 180 after discharge. ]hsCRP levels (picograms/milliliter) will be analysed from blood samples taken by a registered phlebotomist.
- The creatine kinase (CK) levels [ Time Frame: detected at the detected at the in-hospital and the day 7, 14, 30, 60, and 180 after discharge.ay 30, 60, and 180 after discharge. ]The CK levels (picograms/milliliter) will be analysed from blood samples taken by a registered phlebotomist.
- The creatine kinase-MB (CK-MB) levels [ Time Frame: detected at the detected at the in-hospital and the day 7, 14, 30, 60, and 180 after discharge.ay 30, 60, and 180 after discharge. ]The CK-MB levels (picograms/milliliter) will be analysed from blood samples taken by a registered phlebotomist.
- The troponin I levels [ Time Frame: detected at the detected at the in-hospital and the day 7, 14, 30, 60, and 180 after discharge.ay 30, 60, and 180 after discharge. ]The troponin I levels (picograms/milliliter) will be analysed from blood samples taken by a registered phlebotomist.
- The left ventricle wall and cavity dimensions [ Time Frame: detected at the detected at the in-hospital and the day 7, 14, 30, 60, and 180 after discharge.ay 30, 60, and 180 after discharge. ]M-mode images were used to determine the LV wall and cavity dimensions at end-systole and end-diastole from a parasternal long axis view.
- The left ventricle mass [ Time Frame: detected at the detected at the in-hospital and the day 7, 14, 30, 60, and 180 after discharge.ay 30, 60, and 180 after discharge. ]Measurements of LVmass and the short fraction index were automatically derived using standard equations as followed: LVmass(gm) = 0.77 X 10^-3X [(IVS + LVIDd +PW)^3 - (LVIDd)^3 + 2.4]
- The left ventricle ejection fraction [ Time Frame: detected at the detected at the in-hospital and the day 7, 14, 30, 60, and 180 after discharge.ay 30, 60, and 180 after discharge. ]LV ejection fraction (LVEF) was determined using the modified Simpson's method from the apical four-chamber views.
- The left ventricle diastolic functions [ Time Frame: detected at the detected at the in-hospital and the day 7, 14, 30, 60, and 180 after discharge.ay 30, 60, and 180 after discharge. ]Analysis of Doppler pulsed wave was performed to determine diastolic transmitral blood flow velocities for peak early (E) and late (A) fillings and was also detected the diastolic mitral annular tissue velocities for peak early (E') and late (A') fillings.
