[|Human|] i am a 64 years male(50 kg and 5.5 feet height), having Diabetes since past 32 years, 15 days back i have suffered with shortness of breath on investigation it was found that i was suffering from Unstable angina with left ventriculra dysfunction, on echo EF is 35-40%, and on angiography RCA is non dominant and 99% blocked, while LCA is dominant and 90% blocked for which my cardiologist implanted two promus stent in LCA...after angioplasty i feel comfortable for about 2 days then suffered from viral fever with dry cough and shortness of breath (in attack form which last from 20-30 minutes) for which i have consulted my doctor he said that cough is due to ramipril he changed it by losartan, now cough is minimal but attacks of shortness of breath is still there.....what it could be and what should i do in such situation
[|AI|]  Hi, There could be two possible causes. The first one is that you have shortness of breath as a consequence of a viral infection, in this case it will disappear in a couple of days. The second possibility is that it is a heart failure. You noticed that your ejection fraction was 35-40% before the stent implantation, it can cause symptoms for some time until your optimal medical therapy will make your heart failure stable. Take care
