An 80 year old male with CAD with EF 30%, HT controlled with Telmisartan 40 and HCT 12.5. DM controlled with metformin 500 +glimipride. S.creatinine and urea normal. Urine ACR raised. What should be the next step? After streser, Sodium was 126.

HCT is withdrawn. Patient improved 50%. My question is- Can HCT lead to hyponatremia 3-4 years after starting ? 126 Na can be symptomatic? D.D.? Suggest the next step.
