My father had angioplasty to stent an artery to his heart about a month ago and is still very weak and still slightly breathless. He was first alerted to an issue after breathlessness, and tests revealed a blocked artery, but no visible damage to his heart (lungs have also been tested as fine). He had several stents put in the one artery and feel better but says he still feels 'weak' and 'off'. He is obviously on a plethora of medications, but not beta blockers which I thought might have been the culprit. His cardiologist says he will have to have more stress tests in a few weeks, but when they initially looked at his arteries only one seemed obviously blocked. He also complains of an 'odd feeling' in his upper leg, and upper back pain. I worry that we are missing something urgent with these symptoms. Any thoughts?
