<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a stress test tomorrow at 8:00 a.m. and had coffee at 5:00 p.m. Should I reschedule my appt? The first procedure is CDED794.31LXA and the next procedure is EDCD794.31LXA. I am 50 yrs old, 5 ft. tall, weigh 128 and have a family history of heart problems.  <response>: Thanks for your question on Chat Doctor. I can understand your concern. No need to worry about coffee intake. You had taken it before 15 hours of test. So it will metabolize in the body and excreted into urine and stool. So it wont cause any effect of your stress test report. So dont post phone or reschedule your stress test date. Dont worry, you will be done great Im stress test. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
