Im a 26 year old male. I try to stay in shape, y exercising ith weights and some cardio. I have a good diet, eating healthy and avoiding bad foods. I am at my desired weight for my height. My BP does run a little elevated sometimes. In the upper 130s lower 140s. I take several vitamsn a day. Fish oil x 3 , mvi, coq10, magnesium, b complex, vit C, resveratrol, and whey protein. Over the last few years i have noticed a decline in my aerobic capacity. What i used to good do now will leave me winded. My resting hr is usually in the 60s. After jogiing 1/4 mile at a medium pace, my hr will jump to the 150s. I have excessive perspiration with exertion. For example, when i go to the gym there will be overweight older people on a machine going hard and will be barely sweating, winded, still on there after an hour when i leave, and just from weights i will have a hrt of the 150s, and will be sweating profusely. Lately, ive been getting substernal chest pain with exertion. Like after a few minutes of jogging or doing the rower i will get sternal chest pain that worsenes with exertion but subsides when i stop. I will also get it with emotional stress or in a stressful situation. No radiation to extremities or jaw pain. I may not be in optimum shape but i am in fairly decent shape for my age, and eat a healthy diet. I amnot overweight. I have had my lipids checked and my triglecerides were normal and my ldl was 116 and hdl 42. I had a normal resting EKG also. I tried to do a spirometry test for fitness and got extreme substernal pain while tring to blow out hard. I have a significant family history of heart disease and stroke. I take no rx. meds. Could an otherwise healthy 26 year old be experienceing angina. My PCP does not think it neccesary to do a treadmill stress test. Any advise?
