Breaking News: You Can Now Wear Your Heart on Your Sleeve (Literally!)
Well, well, well, folks, it seems like we’ve got a new gadget on our hands that’s just dying to be worn on our torsos. And I’m not talking about the latest smartwatch or fitness tracker. No, no, this little beauty is all about keeping an eye on that ol’ ticker of yours. Say hello to the CardioTag sensor!
Chicago, Where the Action Never Stops (Or Does It, With Heart Failure?)
Apparently, some bright sparks in Chicago have come up with a device that can accurately measure intracardiac pressure without needing to stick anything nasty into your heart. I mean, who needs invasive procedures, eh? The authors of a new study presented at the American Heart Association (AHA) Scientific Sessions 2024 claim that this CardioTag thingy is the real deal. I’m no expert, but I’m willing to bet it’s a game-changer.
The Lowdown on Heart Failure
Now, I know some of you might be thinking, "Heart failure, what’s the big deal? Sounds like a Tuesday to me." But trust me, folks, it’s no laughing matter. Heart failure, whether it’s reduced (HFrEF) or preserved ejection fraction (HFpEF), can be a real party pooper. And measuring those pressure values is like trying to find a needle in a haystack – it’s tricky business. That’s why this CardioTag device is so clever; it offers a non-invasive way to keep tabs on those pesky pressure values.
Dr. Liviu Klein: The Mastermind Behind CardioTag
I must say, I’m impressed by Dr. Liviu Klein, the cardiologist who spearheaded the development of this nifty device. He’s got some serious street cred, folks, and his work at the San Francisco Medical Center has got everyone talking. The SEISMIC-HF I study, which included 943 patients from 15 US centers, shows some mighty promising results. Maybe, just maybe, we’ve got a winner on our hands.
Non-Invasive: The Way of the Future?
It’s no secret that non-invasive technologies are where it’s at, folks. And with CardioTag, we might just have a game-changer on our hands. No more implantable devices or worrying about being stuck in a hospital bed with a bunch of wires attached to your… well, you get the idea. This little device can warn of congestive heart failure, giving us a leg up on treatment and, most importantly, saving lives.
Dr. Jessica Golbus: The Voice of Reason
Now, I know some of you might be thinking, "What about the drawbacks?" Well, let Dr. Jessica Golbus, a panelist at the SEISMIC-HF I trial presentation, set your minds at ease. She’s got some wise words about the benefits of non-invasive measurement and how it can help us sustainably improve quality of life. Long story short: it’s all about early detection and rapid treatment.
The Future of Heart Health
So, what’s next? Well, it looks like the researchers are all set to include more patients in the follow-up study, SEISMIC-HF II. CardioTag’s got some big shoes to fill, but if the results are anything to go by, we might just be onto something. Those hospitalizations due to blood congestion? Not on our watch!
And there you have it, folks – the CardioTag sensor, the ultimate heart-watching gadget. Who knew science could be so… wearable?

Chicago – A groundbreaking study presented at the American Heart Association (AHA) Scientific Sessions 2024 has revealed the CardioTag sensor, a small, lightweight, and wearable device adhered to the sternum, can accurately determine intracardiac pressure to warn of impending congestive heart failure, providing healthcare professionals with a vital tool to monitor patients more effectively.
The researchers’ primary objective was to investigate whether non-invasive technologies, such as the CardioTag device, can provide reliable values for pulmonary capillary closure pressure (PCWP) when compared to established invasive procedures, which have long been considered the gold standard in heart failure diagnosis and treatment. According to Dr. Liviu Klein, a cardiologist at San Francisco Medical Center and the lead developer of the CardioTag device, the technology has shown great promise in offering a more efficient and less invasive alternative to traditional methods.
Heart failure, regardless of whether it is associated with reduced ejection fraction (HFrEF) or preserved ejection fraction (HFpEF), significantly impacts intracardiac pressure. Accurate measurement of these pressure values is crucial for diagnosis, therapy, and prognosis, and the CardioTag device has been designed with this in mind. Dr. Klein emphasizes the importance of closely monitoring patients with heart failure, stating that the CardioTag technology offers a significant advantage in this regard.
Closely monitor patients with heart failure
The CardioTag device was specifically designed to provide a more efficient and less invasive alternative to traditional implantable monitoring tools. According to Dr. Klein, the device offers a unique combination of benefits for both doctors and patients. The device’s ability to provide real-time data and non-invasive measurements makes it an attractive option for those seeking to avoid the risks and discomfort associated with implantable technologies.
The prospective SEISMIC-HF I study, which included 943 patients from 15 US centers, aimed to evaluate the effectiveness of the CardioTag device in measuring PCWP. Patients received a right heart catheter examination and a CardioTag sensor measurement in parallel, with the device’s data including seismocardiography, photoplethysmography, and electrocardiography (ECG). The preliminary results from 310 patients with heart failure have shown great promise, indicating that the CardioTag device can provide accurate and reliable measurements of intracardiac pressure.
Advantages of non-invasive measurement
Dr. Jessica Golbus, a panelist at the SEISMIC-HF I trial presentation and an expert in cardiovascular medicine at the University of Michigan, emphasized the importance of early detection of incipient decompensations and rapid medical treatment in sustainably improving the quality of life for patients with heart failure. She noted that, while implantable devices such as CardioMEMS are currently used to monitor pressure telemetrically, these technologies have significant drawbacks, including the need for surgical implantation and the associated risks and costs.
According to Dr. Golbus, the non-invasive nature of the CardioTag device is a significant advantage, providing a “real-time solution” for healthcare professionals seeking to address clinical questions or unclear next steps. In contrast to implantable technologies, which often require weeks of planning and preparation, the CardioTag device can be easily and quickly applied, providing instant access to vital data.
Dr. Klein confirmed that implantable pulmonary artery pressure sensors are not only invasive and uncomfortable for patients but also expensive. In contrast, the CardioTag device offers a number of distinct advantages, including the provision of pulmonary capillary wedge pressure as the gold standard, rather than the surrogate parameter of pulmonary artery pressure. This is particularly significant for patients with postcapillary pulmonary hypertension, where other parameters can lead to incorrect assessments and jeopardize treatment. Moreover, the CardioTag device provides absolute, rather than relative, pressure values, making it a more accurate and reliable tool in the diagnosis and treatment of heart failure.
Does the AI system improve clinically relevant parameters?
While the SEISMIC-HF I study represents a significant step forward in the development of the CardioTag device, Dr. Klein emphasized that further investigations are necessary to fully realize the technology’s potential. The study’s primary aim was to evaluate the device’s ability to measure PCWP accurately, rather than its predictive value or impact on patient outcomes.
Dr. Golbus concurred, stating that the study demonstrates the CardioTag device’s ability to measure what it is supposed to measure, but further research is needed to assess its predictive value and ability to change outcomes. The next step, according to Dr. Klein, is to conduct the follow-up study, SEISMIC-HF II, which will include more patients and additional centers to ensure the device’s data is representative of all patients.
The researchers’ ultimate goal is to determine whether the CardioTag device is not only suitable for monitoring but also for caring for patients with heart failure. The possible endpoints of the new study include the rate of hospitalizations due to blood congestion, a critical factor in heart failure, where the heart is no longer able to pump enough blood to meet the body’s needs.
