Study on Prediction of Left Ventricular Remodeling Using ST2

Prediction of ST2 for impRovement of Left ventricUlar Systolic funcTion After Percutaneous Coronary Intervention in Patients With acutE Coronary synDrome

Patients who underwent percutaneous coronary intervention after diagnosis of acute coronary syndrome should be enrolled in the study and follow - up.

Obtain written consent for patients who meet all of the selection criteria and who do not meet the exclusion criteria.

ACS(Acute Coronary Syndrome) patients with LV systolic dysfunction(LVEF<50%) on TTE test who underwent successful PCI. At that time, patient proceed with the Baseline blood test(ST2) in hospital.

And then, Medical therapy for 3 months later patient proceed with the Follow-up blood test(ST2) and TTE in OPD.

Inclusion Criteria:

• Subjects aged 19 or older
• Patients with acute coronary syndrome who underwent successful percutaneous coronary intervention
• Patients with left ventricular ejection fraction less than 50% on transthoracic echocardiography
• Patients who voluntarily agreed to participate in the study

Exclusion Criteria:

• Failure to obtain TIMI 3 flow after procedure
• If the remaining life span is less than one year
• Women who are breastfeeding or plan to become pregnant or are planning to become pregnant during the study period
