Last year, I had an angio done, which was completely normal- my Dog told me that I did not worry about anything for the next five years and whatever I get are not heart related A year later, I have started getting heaviness, tightness in my chest, neck, throat, etc - ECG and cardiac enzymes. All good. The cardio said that no need of any testing and I should get physiotherapy or relax my muscle. But I asked on some forum, and I also chatted with Doctor on practo- they all advised that should get a fresh TMT, echo done or stress echo- I was wondering, why do I need these cardiac tests done again ?? is this extra cautious approach
