Edema and Shortness of breath. Attached.

Hello Dr. Since 15 days, i am experiencing edema on feet, legs, hands and face. I also feel heaviness in the same. I am hypertensive since 9 years and on CIPLAR 20(Plain Ciplar not LA) and Telsartan 20 once a day. Before these symptoms started, i was started experiencing irregular/rapid heartbeats for 6 to 7 days. Then these symptoms started. Later, I visited to a cardiologist. He ordered to get my ECG and 2D echo done. Both are normal. LVEF is 60%. nt-proBNP level is 27pg/L. But still when i start normal daily activities, swelling occur with severe shortness of breath. Kidney Function and Liver Function are also normal. (Point to be noted, swelling and shortness of breath prominently occur as soon as even if i start simple simple activities like walking from one room to other room in home) 2D Echo Report is attached. CT Pulmonary Angiogram is attached.
