Dear Mr Shah,
Thanks for writing in. I am a qualified and certified cardiologist. What you are describing are certain physiological tests performed in some research laboratory; so far none of these have known clinical implications. Your symptoms also do not reflect heart disease
. If you are above 35 you need to be seen by a medical doctor
. The doctor after thorough physical examination may like to do an EKG and Treadmill Test (TMT) and if the need is there an echocardiographic examination. You can also get your fasting blood sugar and lipid profile
done. If one of these is abnormal please get back to us in healthcare magic, your query will be answered more objectively and of course scientifically.Good Luck.. With Best Wishes.
Dr Anil Grover
