A person over eighty with chronic heart failure and a young soccer player. At first sight, these two people couldn’t be more different. But, says cardiologist Hareld Kemps, they actually have a lot in common. “The eighty-something year old is also doing top-level sports. With a badly functioning heart, getting dressed in the morning takes the same amount of energy as an endurance training session for a professional athlete. And after this effort, the day’s just getting started.” By looking at heart patients from another perspective and combining his knowledge of both groups, cardiologist and newly appointed Industrial Design Professor Hareld Kemps is working on the development of a new care pathway. “We pay more attention to the person as a whole now, rather than focusing exclusively on the clinical picture.”

Optimizing everything

Due to their limited exercise capacity, older patients with chronic heart failure are often confined to their homes and minimum exercise. Which is detrimental to their everyday functioning, which gets progressively worse. To break this pattern, Kemps calls for detailed custom supervision, similar to what top athletes get. “For a professional soccer player or cyclist, you need to optimize everything. Sleep, nutrition, relaxation… you try to find the right balance both in physical and psychological terms. But an eighty-something year old with chronic heart failure also benefits from such a multidisciplinary approach.”

This is why Kemps and his colleagues looked for options of monitoring patients in their daily lives. The COVID pandemic actually worked to their advantage in this respect, Kemps tells us. “When the hospitals ‘closed’, this had a huge impact on regular healthcare. Suddenly, all we had to supervise our patients were video communication and chat. And we saw it worked great. A semi-annual consultation is only a snapshot; by seeing the patient in their home we found out so much more.”

Bag full of measuring instruments

This is why Máxima Medical Center, as one of the first hospitals in the Netherlands, has been sending its patients home with a bag of measuring instruments over the past years. “These may include scales, a blood-pressure monitor, a thermometer and an oximeter. By getting regular data, we develop a much better overview of the client. And that benefits the patient’s wellbeing and treatment, as well as the care economy. Home-monitoring is still in its infancy, but the field is definitely on the move.”

Through continued development of sensors, such as a heart watch that can monitor patients with chronic heart failure from a distance, Kemps’s research group actively contributes to this progress. Physician-researchers and engineers work together in the group, which Kemps says leads to successful cross-fertilization. “Technology is crucial if you want to monitor patients at home, for one thing in the development of the right sensorics and equipment. We saw, for instance, that a normal ‘Fitbit’ doesn’t function well in heart patients who take certain medication, and that it also needed some adjustment in elderly people with thinner arms and skins. But we also research what parameters you need exactly to monitor a specific patient group, and how you can extract useful information from the heap of data coming in 24/7. The psychological side is at least as important: how do people use medical technology in their home situations? In what way do we motivate patients to change their lifestyles? This requires an adjustment from us as doctors as well, moving away from ‘prescribing pills’ to personalized treatments that ensure someone can function optimally. After all, as a patient you’re more than your disease.”

Thursday, February 8, Máxima MC, TU/e Industrial Design and Eindhoven MedTech Innovation Center (e/MTIC) will organize the symposium Healthy Heart @ Home from 9:30 AM onwards. Directly afterwards, Professor Hareld Kemps will deliver his inaugural lecture entitled Hartfalen is Topsport. More information about the program and registration is available on the website.
