The Effect of Early Administration of Dapagliflozin in STEMI Patients With LV Systolic Dysfunction

The Effect of Early Administration of Dapagliflozin in ST Elevation Myocardial Infarction Patients Presenting With Left Ventricular Systolic Dysfunction

300 STIMI patients with LV systolic dysfunction will be divided into two equal groups (Group I (Study arm, n=150); will receive dapagliflozin plus conventional therapy and group (II) Control arm (n=150); will receive conventional therapy only to detect an improvement in the LVEF by ≥ 5

300 STIMI patients with LV systolic dysfunction will be randomly divided into two equal groups (Group I (Study arm, n=150); will receive Reperfusion therapy: primary percutaneous coronary intervention (PPCI) after DAPT loading (aspirin 300 mg and either clopidogrel 600mg or ticagrelor 180 mg orally) in the ambulance or emergency department upon diagnosis. Anti-ischemic treatment: DAPT, SC-anticoagulation, beta blockers, statin or others will be individualized according to the patient condition. Anti-failure treatment: Angiotensin converting enzyme inhibitors or angiotensin II receptor blockers, beta blockers, mineralocorticoid receptor antagonists, other diuretics will be added in case of volume overload. Dapagliflozin: It will be given in a dose of 10 mg once daily within 24 hours after PPCI. Group (II) Control arm (n=150); will receive Reperfusion therapy: as in study arm Anti-ischemic treatment: as in study arm. Anti-failure treatment: as in study arm. LV echocardiographic analysis for both groups at baseline and 3 month follow up by 2D Echocardiography to assess: LVEF by simpson method Diastolic function LV diameter and volume. LA volume index. LV mass index. Severity of MR. Laboratory investigation substudy analysis: 50 patients from either group will undergo NT-proBNP at baseline and after 3 month follow up. Clinical outcomes: Patients will be followed up in a deducted outpatient clinic for assessment of clinical outcomes either by phone cell or clinic visits at 3 month. Patients will be assessed for the following clinical parameters: I. Composite of CV death and rehospitalization of HF. II. Individual component at composite end points. III. Reinfarction or readmission for ACS and target lesion revascularization. Research outcome measures: a. Primary (main): 1. The improvement in the LVEF (≥ 5%) using biplane simpson method echocardiography. a. Secondary (subsidiary): Echocardiographic parameters at 3 month follow up. Changes in LV remodeling. Changes in diastolic function Changes in LA volume index. Changes in LV mass index. Laboratory investigations. Changes of the NT-proBNP from baseline to 3 month follow up Clinical outcomes at 3month. I. Composite of CV death and rehospitalization of HF. II. Individual component at composite end points. III. Reinfarction or readmission for ACS and target lesion revascularization.

Reperfusion therapy: primary percutaneous coronary intervention (PPCI) after DAPT loading (aspirin 300 mg and either clopidogrel 600mg or ticagrelor 180 mg orally) in the ambulance or emergency department upon diagnosis. Anti-ischemic treatment: DAPT, SC-anticoagulation, beta blockers, statin or others will be individualized according to the patient condition. Anti-failure treatment: Angiotensin converting enzyme inhibitors or angiotensin II receptor blockers, beta blockers, mineralocorticoid receptor antagonists, other diuretics will be added in case of volume overload.
