As long as you aren't having an angina episode, you should be able to have fillers. It can take up to 2 weeks for final results. Hope this helps.
It depends on what you mean by angina, if it’s something that is happening often you need to see a cardiologist and worry later about lip enhancement, but if you have chronic chest pain that has been evaluated by a cardiologist and you are stable then by all means you can get treated with lip fillers.
