Hi! I'm 23 years old and i was having mild chest pains which then after suggestions from doctors resulted in a lot of tests. I have a small hiatal hernia. I also had an echo cardiogram and a coronary angiography(CT). Test results showed 40-45 LVEF and 40% blockage of LCX. Cholestrol was a little above the optimal level, the bad cholestrol was little less. When i had that test, i wasn't exercising as i was preparing for an exam. Now i'm working out which is fine, i don't get tired easy.. can run lengths easily. But, it scares me about my heart. Should i be worried about having a failure or an attack at such an age? My family does have a history of having heart attacks. I eat outside food once or twice a week, nothing fried. I sometimes feel full of breath, unable to take in full breath. Other than that and some pain in chest at times, i'm all fine and feel fit. But the results have scared me and i am constantly worried that what if i get an attack. My cardiologist gave me carca 10 mg and aspirin. i quit taking medicines a while ago. Please help.
