Hi,Help! My wife had a stress test recently because her family doctor just purchased stress test equipment(note
Hello thanks for posting here.  I have gone through the findings of the stress imaging. It is a very sensitive test for diagnosing coronary artery disease. By the reports of her stress imaging it appears she has multiple areas of blood supply insufficiency. It is a quite sensitive test and there is no reason to suspect report or images may not be accurate because it is new. Also, a faulty machine would not show so many deficiencies. So she definitely has significant coronary artery disease which is indicated by multiple areas of perfusion abnormality with decrease in contractile function to 36% and amnesia/hypokinesis. Should she undergo a conventional angiogram and not a CTA? CTA has more of a role in patients in whom diagnostic tests are negative, but the patient has heart related complaints. So basically it is to rule out coronary artery disease in patients who are less likely to have coronary artery disease. In her case, since there is a strong suspicion of coronary artery disease, conventional Anglo must be done. Also, CTA is not very good at quantifying the severity of a block. Also, even if she undergoes a CTA, and some blocks are diagnosed (which will come up in her case), the next step would be a conventional angiogram. So the ideal way to proceed from here is a conventional angiogram and definitely not a CTA. Wishing her good health. Regards
