My ecg, echo, tmt are normal I have a bit high cholesterol. I have consulted two cardiologists and they said that my heart is fine. My question is should I go for ct angiography my parents are restricting me from the test saying I have become hypochondriac. Please help me what to do. I am 28 age old.
