I am 60 year old from Malaysia and had angioplasty done 3 days back. Since, then I get dry cough when I try to sleep and not able to sleep till morning. I first thought it was because of some oily food. So I eating boiled food since then. No relief. Then I thought it was reaction to some medicine so I stopped taking all medicines except Clopidogrel 75. Still no relief. I asked a general practioner friend. He told me that my heart may have weakened and there could be a leak to lungs. I am worried. Please advise what to do. The angioplasty was done in public hospital where it takes months to get an appointment. Thanking in anticipation. Ajay Chauhan
