OUR RESEARCH is focused on applied data science methodologies for clinical decision-making in cardiovascular disease and other applications. Specific topics include atrial fibrillation, drug-induced long-QT syndrome, preventive cardiology including lipid management, and programming of cardiac implantable electronic devices (e.g., pacemakers). We collaborate with several data science engineers, health services investigators, clinicians, and biostatisticians across multiple University of Colorado campuses, as well as outside institutions. Our team has experience in the analysis of data from wearable and implanted medical devices, genetic data, electronic health record data, and data from commercial wearable devices (Fitbit and AppleWatch). We have developed both web-based and smartphone prototype applications, with ongoing clinical testing focused on the N-of-1 trial approach.

Despite a number of innovations in the ablative treatment of atrial fibrillation, decisions around rhythm management remain a challenge due to a wide variation in the symptoms and presentation across patients. Such variability motivates approaches that can individualize treatment decisions, in a manner that also allows for the ever-expanding range of options that could be available as technology improves. The method we have applied to develop clinical decision support models to guide rhythm-management decisions is called reinforcement learning, which is a type of machine learning that allows the model to learn from experience to identify the optimal treatment approach for each individual patient.

Drug-induced prolongation of the QT interval (diLQTS) on an ECG is a common side-effect of many medications, and is the number one reason for FDA rejection of new compounds due to the risk of life-threatening arrhythmias. Methods to predict which individuals are at greatest risk of diLQTS, and guide decisions about how to manage risk, could have a significant impact on management of conditions across many clinical domains. Our team has studied risk of diLQTS using machine-learning methods, genetics, and through analysis of existing electronic health record tools created to prevent diLQTS. This work has led to greater understanding about both the risk of diLQTS, but also how human behavior factors into use of decision-support tools applied at scale across an entire healthcare system.
The deluge of data that has emerged with advances in wearable and implanted devices has enormous potential to guide individualized decisions for patients. However, the process of extracting meaningful information from this data remains a major challenge for the field. Our team has examined data from both commercial and medical-grade devices to identify potential applications in both cardiology and health/wellness, which has included development of several applications for smartphone or web-based use. The insights from this work have led to projects centered on the N-of-1 approach to using each person’s data in a manner that can have the greatest impact on their health.
