Sodium Tanshinone IIA Sulfonate in Left Ventricular Remodeling Secondary to Acute Myocardial Infarction

Phase 4

• Conditions: Left Ventricular Remodeling; Acute Myocardial Infarction
• Interventions: Drug: sodium tanshinone IIA sulfonate; Other: control

• Registration Number: NCT02524964
• Lead Sponsor: Guangdong Provincial Hospital of Traditional Chinese Medicine

Brief Summary

Approximately 60 patients with ST-segment elevation myocardial infarction successfully treated with primary percutaneous coronary intervention will be enrolled and randomized to receive the sodium tanshinone IIA sulfonate in addition to standard therapy or the same volume/day of normal saline.

The primary endpoint is the variation in LV end-diastolic volume index (LVEDVi) assessed with cardiac magnetic resonance imaging (MRI) at baseline and 6 months.

Detailed Description

The primary endpoint is to determine whether sodium tanshinone IIA sulfonate could prevent LV remodeling among patients with completely reperfused AMI after PCI, detected by 6 month change in LVEDVi measured using cardiac MRI when compared to placebo.

Secondary endpoints will include cardiac MRI measures of variations in microvascular obstruction, defect size, ventricular wall motion score, wall thickening, global LV ejection fraction, ventricular volumes (LV end-systolic/ diastolic volume) and myocardial perfusion during the same interval.

Furthermore, the investigators will determine the variation (change from baseline) of biomarkers indicating myocardial fibrosis (PICP, PIIINP, ICTP and MMPs) and NT-ProBNP at 1 and 6 months after AMI.

Additional efficacy endpoints will include 6-minute walk test, New York Heart Association functional classification, Seattle Angina Questionnaire score and incidence of cardiovascular events (defined as cardiogenic death, stroke, recurrent myocardial infarction, readmission on account of deterioration of congestive heart failure or unstable angina, target vessel revascularization) at the 6-month follow-up will also be analyzed to evaluate the efficacy of sodium tanshinone IIA sulfonate treatment.

variation (change from baseline) of biomarkers indicating myocardial fibrosis	6 months	type 1 collagen telopeptide (ng/mL), aminoterminal propeptide of type I procollagen (ng/mL), aminoterminal propeptide of type III procollagen (ng/mL), matrix metalloproteinase2 (ng/mL), matrix metalloproteinase9 (ng/mL) at 1 and 6 months after AMI.
cardiac magnetic resonance imaging measures of LV remolding	6 months	cardiac magnetic resonance imaging measures of variations in left ventricular end-systolic/ diastolic volume (mL) during the same interval.
cardiac magnetic resonance imaging measures of microvascular obstruction	6 months	cardiac magnetic resonance imaging measures of the frequency of delayed or absent wash-in of contrast agent into the infarct zone.
major adverse cardiac event	1 and 6 months	frequency of the reported cardiovascular events (defined as cardiogenic death, stroke, recurrent myocardial infarction, readmission on account of deterioration of congestive heart failure or unstable angina, target vessel revascularization)
6-minute walk test	6 months	A 6-minute walk test measures the distance patients can quickly walk in 6 minutes. (in meters)
New York Heart Association functional classification	6 months	I Cardiac disease, but no symptoms and no limitation in ordinary physical activity, e.g. no shortness of breath when walking, climbing stairs etc.; II Mild symptoms (mild shortness of breath and/or angina) and slight limitation during ordinary activity.; III Marked limitation in activity due to symptoms, even during less-than-ordinary activity, e.g. walking short distances (20-100 m).Comfortable only at rest.; IV Severe limitations. Experiences symptoms even while at rest. Mostly bedbound patients.
