[|Human|] My 65 year old mother -in law has recently (2monthd back0undergone angioplasty with one medicated stint placed. she also has cervical spondilyitis. now suddenly she got great breathing difficulty but upon hospitalization all tests for cardiac, chest and pulmonary side came normal... But just after 2 days again she felt severe shorthness of breath What can be possible reason of such breathless ness
[|AI|]  Hello, If everything is normal from cardiac and pulmonary side, other cause must be ruled out. May I know her BMI (Body Mass Index)? Is she obese or overweight ? Does she snore during sleep? She may have OSA (Obstructive Sleep Apnea) or central sleep apnea due to some Chat Doctor.  Just ask your doctor to check that or go for polysomnography. Hope I have answered your query. Let me know if I can assist you further.
