Thank you so much to both Norma and the Doctor.
Interpreting just the report you provide, your stress test was negative for any inducible ischemia (decreased blood flow to your heart). The study was adequate because you were able to achieve > 85% of your maximal heart rate, and your functional capacity is good (11.7 METS) which is a good prognostic indicator. Stress tests are not able to say definitively whether you do "not" have coronary artery disease as this can only be done via coronary angiography where your coronary vessels are viewed directly. However, this is a "functional study" which assesses whether there is any supply-demand mismatch, which in your case, was normal. Your relatively young age puts you at low risk for coronary artery disease at this point. With your negative stress test, your symptoms are very unlikely to be related to your heart.
Regarding your last question, a stress test is unable to determine whether you have high blood pressure or not. A true diagnosis of high blood pressure is made when your resting blood pressure is > 120/80 on 2 separate occasions separated by at least 2 weeks.
Hope this helps.
I've been a heart patient since I was 26- and on meds for it since. I'm not a doctor, but I'm pretty good at reading reports like the one you quoted. Until a real doc answers, I'd like to ease your mind- the report is great. Totally. I have no clue what your chest pain and shortness of breath are from, but it looks like your heart function is super. Hope the doc that does answer does so soon so you'll feel more confident. Regards- Norma
