[|Human|] I had a stent implant last October and in December I again had angina attacs. My doctor said it was unusual and does not quite know what could be causing it. I had a additional CAT last week and it showed muscle spasms after the position of the stent. any other reasons for the angina attacks, they usually happen between 6 and 10 am. Nitro does help, but do I have to take it for the rest of my life?
[|AI|]  Hi, This type of angina is caused by a heart vessel spasm. Usually it s diagnosed with coronary angiography with a special method. Early morning is a common time for such angina. Treatment is with nitrates and/ or calcium channel blockers. You should initiate the treatment, and it will be better if you take long-lasting nitrate before going to bed and not only nitroglycerin during an angina attack. There are chances that the disease may stabilize in 6 months, and you can with Chat Doctor. Take fearsome back if you have any further questions
