Caffeine - effect on stress test?

bigdaddy1111 posted:
Hi there, I had a stress test today where my cardiologist said I had an abnormal EKG and wants to do an echo stress test next. He thinks either it was a false positive or I have a blockage of some type. I realized later that I had drank a lot of coffee in the hours before my stress test, and also had a piece of lasagna immediately before leaving for my appointment. Could this have thrown my test off? I realize I probably sound like an idiot, but there were extenuating circumstances! I have low cholesterol and was not even remotely tired during the test (sweating but not tired). I got to 5mph 18% grade before the nurse turned it off. I hope I stupidly threw off the test, but I'm worried! Thanks. JC

Hi JC: As reported, since caffeine consumption can affect the heart rate and rhythm, this may/can affect diagnostic tests, such as cardiac stress tests (especially if/when a stressor agent was used in place of physical exercise). Most important, communicate/interact well with your doctors. Best of luck down the road of life. Take care, CardioStar☆ Advocate for ♥-Health - - b ☑Be well-informed b HeartSite Heart info, cardiac tests (commonly performed, mainstream types) info, actual diagnostic images. b Coronary artery anatomy ☞Starting with the left anterior descending (LAD), the most critical, next to the ultra-critical left main (LM). www.heartsite.com/html/lad.html - b Good to know, for the primary and secondary prevention of heart attack and brain attack/stroke. Epidemiologic studies (EDS) have revealed risk factors for atherosclerosis (typically affecting the coronary, carotid, and peripheral arteries) which includes age, gender, genetics (gene deletion, malfunction, or mutation), diabetes (considered as being the highest risk factor), smoking (includes secondhand), inactivity, obesity (a global epidemic, "globesity"), high blood pressure (hypertension), diet high in fat, saturated fat and cholesterol, high LDL, high Lp(a), high ApoB, high Lp-PLA2, high triglycerides, LOW HDL (less than 40 mg/dL, an HDL level of 60/65 mg/dL or more is considered protective against dreaded coronary artery disease), high homocysteine, and high C-reactive protein (CRP/hs-CRP). - i Quote "Be a questioning patient.

You can have a false positive stress for a number of reasons. They're actually pretty common. Looking at your risk factors can be helpful in identifying whether your at risk for coronary artery disease (CAD). High blood pressure, sedentary lifestyle, family history, smoking, and high cholesterol are just some of the things that may be a red flag that you may have coronary artery disease and may warrant some further testing by your physician. Just follow your physicians instructions and if you do have some risk factors for CAD try and modify your lifestyle to help you stay healthy. Hope this helps.
