I am 46 year old male 5"10 255 lb I will admit that I have high anxiety . My hdl levels fluctuates between 32 to 41. ldl hovers between 90 to 120 , triglycerides about 140 to 170 total cholesterol usually averages 177 for the last 6 years, I had a clean heart cath 2004, and 2009 . 2005 MRA results 20 percent kidney artery stenosis . Had mra done because of uncontrolled high blood pressure. I have PACs and has been recorded on ekg .I have gerd and some mild scaring on esophagous Sometimes I have . chest pains and discomfort in left shoulder and , tingling in index and ring finger , sometimes in middle of chest but I think due to gerd. Last couple of weeks I have been awaken in bed by chest burning or pain . I will drink some water and it went away. I did the calcium score test last year and it was 0 which I know there is some disagreement in the medical community about the accuracy of this test . My question is should I repeat another treadmill stress test to rule out any possible blockages and how long is a heart cath good for ? I am afraid being mark a hypochondriac by my gp and cardiologist but I know my body and they are not in it .........I am . thanks.
