Hello,
Thanks for writing to Health Care magic, I am Dr , Muhammad Ahmad , I have read your question closely, I understand your concern and will be helping you with your health related problem.
This word "tight" is not a scientific term as such but doctors in general use it after
stress testing when there is an
artery which has some blockage , usually this blockage is not significant to ask for a stenting but it is significant to cause some ECG changes in the stress testing.
You and your husband do not have to panic, these kind of arteries just need care, by care i mean taking regular medication , physical activity, keeping check at your diet and staying in contact with doctor and pay regular follow up visits as advised by the doctor.
This slight tightness will only get worse if care is not taken otherwise it will regress and things will keep getting better with time.
I hope this answered your question, If you have more queries I am happy to answer you.
Regards.
Dr.Muhammad Ahmad
