Are there differences in the experience of micro vessel angina and unstable angina? I have had major vessels stented, but still experience angina when in the cold, or hot or damp, stressed, on inclines, alcohol, coffee, stairs and carrying weighty items, or speeding up too fast. GTN helps. I can exercise quite heartily, if I take time to warm up. I also get angina when lying down or resting, even being woken up by it. GTN helps but it returns quickly.
Consultants seem to have varied views of these two types of angina. Some say i have both stable and unstable angina. Some say I have microvessel angina.
What’s the relationship between the two? If small vessels are blocked then surely that can reduce oxygen to major organs, in just the same way as when major vessels are blocked? Won’t these feel the same?
