I have a resting pulse rate of 129 along with shortness of breath. All test have all come back negative for heart disease. I have taken a EKG, stress test and cat scan of the heart. All normal and I am considered low risk for a cardiac event. My diabetes is well controlled. blood pressure well controlled. Cholesterol under 190. I am thinking about having the test to check my arteries. any suggestions. Test for thyroid, lungs and everything are negative. I have been put on a beta blocker to lower the heart rate. The shortness of breath and fatigue is still present and seems to be getting worse.
Thanks for your question on Chat Doctor. I can understand your concern. Since you are diabetic, we should definitely rule out pulmonary embolism and coronary artery disease (CAD) in your case. So get done coronary angiography and CT pulmonary angiography. If both these are normal then no need to worry much. Sometimes, undiagnosed stress and anxiety can also cause similar symptoms. So consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic Chat Doctor.  Don't worry, you will be alright. Avoid stress and tension, be relaxed and calm. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
