The global interventional cardiology market is anticipated to expand at a compound annual growth rate (CAGR) of 7% over 2018–2023, generating USD 23.39 Bn in revenue by 2023.Interventional cardiology procedures such as continuous cardiac monitoring or heart monitoring help to capture irregular heartbeats, which in most cases go unnoticed, as the patients experience no symptoms. Cardiac monitoring is recommended by doctors who may suspect health problems such as a sudden stroke or breathing problems is related to the heart. Cardiac monitors detect or rule out a heart rhythm disorder and determine the future course of treatment.  Continuous heart monitoring help explain conditions such as unexplained fainting and heart attacks, atrial fibrillation and heart palpitations.

The challenges of previous technology

Cardiac monitoring technology has evolved since the 1990s, from transferring data via a phone line, to going wireless to now using Bluetooth and other cellular technology. The functioning of the device has not changed much, however, the devices have become smaller, more compact and easier for patients to use.

Holter monitoring is seen as the standard option for cardiac monitoring, however, found its bulky design to be hampering their daily movement and disrupting their routine activities. Holter monitors track cardiac activity for 24 to 48 hours and patients need to keep a diary record of their symptoms, which leads to an inaccurate collection of information. This method is deemed inefficient and lengthy by many clinicians.

Where cardiac monitoring is heading?

The latest cardiac monitors available in the global interventional cardiology market provide a comprehensive, patient-friendly and complete heartbeat monitoring system for clinic-based or in-office healthcare. Less invasive, newer, wearable monitors that offer this type of long-term data beyond 48 hours include the Cardiac Insight Cardea Solo, PocketECG, ScottCare novi Patch Holter and the BardyDx CAM Ambulatory ECG Monitor Patch, to name just a few.  These new devices are smaller, compact, lightweight, disposable, and water resistant and can be worn for up to a week. This time period is perfect to detect irregular heart rhythms such as atrial fibrillation (AF), hence allowing for efficient diagnosis. Once the seven day period is completed, it is easier to access the information. The electrical module is removed from the patch by the clinician and plugged into their computer, an automated draft ECG analysis summary report is produced by the software. The software allows frontline clinicians to perform application, data analysis, and professional review and interpretation without delay and without the need to outsource sensitive protected health information (PHI). Today’s software is cloud-based and allows for more capabilities and power. This power provides accuracy, sensitivity, and specificity. 

The future of cardiac monitoring is still bright.

Everyday wearable devices will play an important role in cardiac monitoring and ensure two-way communication between doctors and patients. In the years to come, a watch will be able to detect cardiac abnormalities early on and prevent major heart ailment. While technology has improved the size and capabilities, it has not been able to automate the art of reading the test results, and the need for highly trained staff still remains.

Smarter algorithms and software combined with cheaper and more accurate devices will continue to provide better results.
