I weigh 197 but was 224 three months ago. I am 5'8" and have no history of heart disease in my family. My blood pressure is a little high and my cholesterol is normal. My LDL was 120 three months ago before I started losing weight. I have been having chest pain for three months now along with palpitations. The palpitations seem to get worse a day after I do any exercise. In the three months, I have gone running once and when I ran that time the chest pain increased and felt like an ache on the left side of my chest. I have had 6 kg numerous blood work, an echocardiogram, a stress test, and a stress echo test that all came back normal and I did not feel any chest pain during the stress and stress echo. The chest pain seems to come after I have walked a while or when I am stressed even though I have not felt the pain much since I got my result for my stress echo I would say because I have been calmer and also when I wake up some morning I can feel the ache right below my chest. The situation has completely taken over my life as I worry day and night. What are the chances of it being coronary artery disease?
