Questions & Answers with Dr. Jess Goodman

Your questions, answered.
Last Thursday we hosted a Question and Answer with Dr. Goodman, Chief Medical Officer and inventor of iHeart. We received questions via email, facebook, and twitter and we’ve published the answers for you guys to enjoy! We will be hosting another live Q&A, this time with video, in the upcoming month! Stay tuned.
How accurate is iHeart algorithm used in calculating APV?
Arne via email
Dr. G says: Hi Arne, the iHeart method of calculating Aortic Pulse Wave Velocity was tested against the Sphygmocor Aortic Pulse Wave Velocity PWV testing system, that is the world's "gold standard" PWV testing system and the iHeart device is found to have high correlation with Sphygmocor!
iHeart data from thousands of recordings shows exactly the same relationship with age as shown by published Aortic Pulse Wave Velocity data in the scientific literature
We're currently working with Ryerson University in Toronto, Ontario to conduct a validation study to be published in the near future in a peer reviewed journal.
How does iHeart tell me how healthy I am?
Ron, via Twitter
Dr. G says: iHeart is a measure of aortic stiffness. Aortic Stiffness has been proven in the scientific literature to predict overall health and risk of death from all causes. Aortic stiffness is a way of measuring stiffness along the spine effecting mobility of organs in the chest, abdomen, and pelvis. With each breath, the organs receive a massage, promoting internal circulation. With increasing spinal stiffness and decreased core mobility, organ circulation suffers, health declines, and lifespan is decreased.
Can I use iHeart on my child?
Brenda, via email
Dr. G Says: iHeart has been tested only 18 years of age and older, it is not accurate for testing people younger than 18, or older than 80 years old.
Why do I have to be sitting when I test?
Tammy via Facebook Messenger
Dr. G says: iHeart readings are sensitive to Aortic Stiffness and blood pressure. With standing blood pressure falls and a reading taken after standing up will show lower Aortic Pulse Wave Velocity and younger Internal Age. It is important to sit for at least two minutes in a relaxed way before doing an iHeart test to control for blood pressure effect.
Do medications affect iHeart readings???
Tom via email
Dr. G says: Blood pressure and cholesterol medications have a very powerful effect to reduce Aortic Stiffness and people on these medications will often have a reading that is younger than it would be without the medications. If your readings are good, it means that your blood pressure or cholesterol medications are working, which is a good thing! Keep up with healthy lifestyle choices like walking/exercising every day and eating a diet full of nutritious foods including those rich in omega 3s.
Why does my internal age vary so much?
Martin via Facebook Messenger
Dr. G says: The human body is very dynamic, even though Aortic Stiffness changes very slowly over weeks, months, and years, blood pressure can change remarkably over even a few minutes. Because iHeart is blood pressure sensitive, you will see some variation because of blood pressure effects. If you have a coffee, that increases blood pressure and you will see your Internal Age rise within half an hour and slowly return to baseline.
If you go for a hike, you will see your Internal Age drop - both because your blood pressure is lower after exercise and because you've stretched through your core and reduced Aortic Stiffness.
What's the best way to use iHeart?
John via email
Dr. G says: Getting a series of baseline iHeart readings at about the same time in the morning every day for 4 or 5 days will give you an understanding about your true Internal Age. You can then try different activities to see what has the most positive effect on Internal Age and experiment to see what works best for you. Everyone is different and iHeart is a tool that allows you to see how different kinds of external stimulus effects your body. For example, exercise, diet, stress levels, sleep, energy levels, etc.
Make sure you consistently take your baseline reading multiple times throughout the week to make sure you're still on track.
What type of exercise gives the best iHeart results?
Sindy via email
Dr. G says: Exercise that works the whole body and especially stretches along the axis of the spine will have a beneficial effect on Aortic Stiffness. Exercises like walking, yoga, and pilates, elliptical training, tai chi, hiking, all encourage good movement of the body's core resulting in improved core mobility.
How can the stiffness of my aorta change so fast? Isn’t that weird?
Tony via email
Dr. G Says: iHeart measures Aortic Pulse Wave Velocity, that is influenced by both aortic stiffness and blood pressure. If iHeart Internal Age is changing in a significant way in a short period of time, it is blood pressure that is responsible, not changes in Aortic Stiffness. To make sure you're testing correctly, sit for two minutes before each test with no movement, and perform your baseline test at the same time each day.
Is iHeart a novelty item? Internal Age sounds made up.
Ted via facebook
Dr. G says: Internal Age is a lot easier to understand than Aortic Pulse Wave Velocity. Knowing that you are older, or younger, than your chronological age is a simple way of appreciating whether you have Aortic Stiffness that is higher or lower than most people your age. iHeart was designed to make it easy to use Aortic Stiffness and Aortic Pulse Wave Velocity as a guide to better health and longer life, and is set up to show people improvement with exercise, good diet, and stress management.
Are you a heart doctor?
Jim via twitter
Dr. G says: Although I am not a specialist and only a GP (General Practitioner) I try to be a doctor with a big heart. My goal is to give everyone an ability to use iHeart for Aortic Stiffness monitoring in order to feel better and live longer. I've been studying Aortic Stiffness and Pulse Wave Velocity for about 25 years, ever since my Tai Chi teacher, a Taoist Monk, encouraged me to show people why they should stretch between the heart and the kidneys, along the spinal axis where the Aorta lies.
We're looking forward to answering many more of your questions during our next Q&A, which we will announce soon! Stay tuned.
