Hi
I have CAD and Angina. After an unsuccessful spell on Isorbide I have been taking 20mg of Nicorandil every day for two weeks. Initially it seemed I was able to exercise more freely, by which I mean climb my stairs in one hit!
But now whenever I do anything mildly energetic, like walking, I get this unbearable tightness across my chest and my heart pounds. I have to rest every 200 yards or so, but even when I rest my chest remains very tight for up to an hour. It feels like I have a horse sitting on me! My GTN spray provides some relief, but only briefly.
It’s not painful but it’s very unpleasant. Has anyone else experienced this? The NHS website says to call an ambulance.
