Cardiac bio marker- Is normal but doubt?

Hlo! I had asked a query about chest pain in morning... chest discomfort radiating to my left arm sinxe 3 days. Unable to walk for long, do simple activities like bathing, walking coz pain. The night before felt an impending sense of doom. Today noon at ER ekg + echo done which is normal but doubt regarding blood work HIGH SENSITIVITY TROP I ( Hs TNI) = 0.01 ng/ml... and CK- MB = 20 ug/l Are these values despite being normal concerning as they r towards higher side esp CK-Mb whose upper cut off is 25? For someone like me who has chest pain are these two values pointing towards anything? I have been given complete cardiac clearance from my hospital and I believe on it but still my anxious mind needed more reassurance about these enzymes I hope it's all good and I can be at peace that the discomfort I had in past 2 days Wasnt my heart??
