Congestive heart failure i was diagnosed with chf and a 80 percent block of the right coronary artery my ejection fraction is up to 55-60 from 25-30 i still get tired and short of breath not getting answers from my doctor could that be from the block any

That : That is great news that your ejection fraction (ef) has improved that much, as that is directly correlated with your overall long term prognosis. You clearly are still symptomatic though. If you find that your shortness of breath continues, it is certainly possible that the stenosis in your right coronary artery is the culprit, although without knowing more information it is hard to say definitively. My best advice to you is to find a physician that will answer your questions and communicate with you so that you may understand your care. Heart disease is complex and involves the interplay of many factors, and an excellent relationship with your cardiologist can be the most important one.

Yes: To function well your heart muscle needs an ample supply of oxygen and glucose. When there is such a narrowing the heart muscle is not getting enough fuel to maximize performance. The meds boost it some & lessen the work, but your brain wants your body to do more than your heart is able to support. There may be other options to improve your situation so get back with the doc & discuss it.
