Hi friend,
Welcome to Health Care Magic
You have not said of any characteristics of the pain – pain from the heart is oppressing, in central chest (and left), worse on effort, relieved by rest, may radiate to shoulders and arms, associated with sweating and so on...
Your symptoms do not suggest Coronary Artery Disease (CAD).
ECHOcardiogram is necessary to see the heart valves (
Mitral Valve Prolapse) / heart muscle (
Cardiomyopathy) and heart function (
Ejection fraction, wall motion abnormality) / clots...
TMT – Treadmill exercise ECG; may be with thallium isotope – is necessary to evaluate
ischemia (reduced blood flow / Coronary Artery Disease)
Take care
Wishing speedy recovery
God bless
Good luck
