30 patients will receive standard of care only which includes ACE inhibitors, ARBs, beta-blocker, mineralocorticoid receptor antagonist, and loop diuretics according to case demand.

30 patients will receive empagliflozin for 90 days in addition to standard of care. empagliflozin will be administered at a starting dose 0.25-0.5 mg/kg/day (maximum 25 mg per day) enterally once daily using available 10mg and 25mg tablet for at least 30 days to patients already receiving standard HF medical therapy. Assess for glucosuria no sooner than one week after starting empagliflozin with target of 1+to 3+. If negative or trace glucosuria, increase dose to maintain target 0.25-0.5 mg/kg/day (maximum 25 mg once daily). for patients who cannot swallow tablet, tablet of 10mg will be crushed and mixed with 10 ml of water to make concentration of 1mg/1ml and calculated dose given from this solution
