am I going to have a heart attack?

I have cold like symptoms, slight chest discomfort mostly at night when resting and not with exertion, slight fatigued someTimes, the cold symptoms feeling of chest congestion slightly, body aches, head aches, feeling of a fever but don't actually have a fever, I've had heart palpitations for years, punding, racing (with walking) and skipped beats usually when lifting things, the cold symptoms have beeb going on for a few weeks but I feel fone during the day I only get the symptoms at night. I've had ekg, countless blood work, chest xray, and a stomach and chest ct scan all that this year.

What should I do? I don't have a family history of heart attacks and I'm a 22 year old male not over weight.
