A cardiologist who suspects that a patient has a heart issue might first order a stress test. Then, depending on the results, they may need to do a more invasive procedure that involves putting a camera inside the vessels of the heart to see if there is a blockage. Do some research to find out what the medical term for this procedure is. Then discuss whether you think it is a good practice to do the stress test first or if you think the cardiologist should skip the stress test and go straight for the more invasive procedure. Explain at least one reason behind your opinion.
