No any sort of medical expert here Em as you well know, but my ( and Sqad knows this because he kindly gave me soime information on the matter at the time) my 'grandfather' suffered a major heart heart attack in March , followed shortly after by another and then an attack of heart failure. He also has claudication and can't walk above about 5 metres without getting breathless. He has seen every consultant possible, had extensive MRA scans on his arteries regarding his leg pain and they have decided to treat the whole matter quite aggressively firstly with drugs, then with stents to his leg arteries ( which he has not had done yet) further cardiac stents ( again due for those shortly) with the idea of a bypass in 2-3 years.
His breathing was truly appalling due to COPD and his legs and lungs were filling with fluid, however they have him on a drug regime which helps tremendously. The consultants have taken a lot of trouble to try to improve his quality of life (and are thus far succeeding), so I really think it's worth your friend pushing to be seen and treated properly.He only stopped smoking after the first heart attack in March of this year.
His drug list is as follows:-
Tricagrelor 90mg twice daily
Atorvastatin 80mg daily
Ivabradine 5mg twice daily
Ramipril 2.5mg daily
Glyceryl Trinitrate spray as required
Ipatrorium Bromide inhaler 2x 4 times per day
Salmeteraol Xinafoate 2x twice per day
Aspirin daily
Omeprazole ( for an unrelated gastric issue)
Novomix ( for diabetes)
Salbutamol inhaler as required
Furosemide 40mg Twice daily
Sitagliptin 100mg daily
And finally Nicorandil 10 mg twice daily which seem to have made a huge difference as they were only prescribed 2 weeks ago.
My point is prior to his heart attack ( apart from the insulin) he was on no medication whatsoever and very, very poorly. Although he's not going to be running any marathons soon, his consultants have his quality of life at the top of their minds and have his scheduled for surgery to improve it still further, so you really must press your friend to push for treatment, it has made a world of difference to Calumn, who also railed he wasn't having a motability scooter but we got him one anyway and he now uses it after having a really good think about things. I hope your friend presses for the help he needs.
