Second Opinion. Related to heart or not?

I did an ECG 10 days ago (after reading about recent spate of heart attack news in Indian youth) to keep a tab on my heart health. ECG came normal. Day after that started feeling uneasiness and discomfort in my chest (left and right side) with a mild ache extending to my left hand underam along with indigestion. Went to a cardiologist 8 days ago for consult, another ECG was taken, again it came normal but the discomfort was still there. Yesterday echocardiogram and stress ECG (TMT) was done, which I'm attaching here. Kindly suggest me if the reports are normal because the indigestion and uneasiness, though not as intense as they were initially, still persist. Please tell me if the problem is related to heart or not? My weight and height measurements are 80kgs and 5'9" respectively.
