I'm new here though I have been reading a lot of the posts. Was diagnosed with angina nearly a year ago. I've had HBP for many years, probably genetic and was already taking Doxazosin, Felodipine, Losartan, Atorvastatin and an aspirin. The Cardiologist added Bisoprolol and 10mg Isosorbide twice a day. On top of all this I have had to use the Glyceryl spray, more so during both winter and a lot during the hot summer. if I feel myself getting breathless I try to sit down and wait to see if it passes. My GP says I should be using it as soon as I get breathless. Any advice.
