Electronic physician notification to facilitate the recognition and management of severe aortic stenosis: Rationale, design, and methods of the randomized controlled DETECT AS trial.

BACKGROUND: Symptomatic severe aortic stenosis causes substantial morbidity and mortality when left untreated, yet recent data suggest its undertreatment. OBJECTIVE: To evaluate the efficacy of electronic physician notification to facilitate the guideline-directed management of patients with severe aortic stenosis. HYPOTHESIS: We hypothesize that patients with severe aortic stenosis who are in the care of physicians who receive the notification are more likely to undergo aortic valve replacement within one year. METHODS/DESIGN: The Electronic Physician Notification to Facilitate the Recognition and Management of Severe Aortic Stenosis (DETECT AS) trial is a randomized controlled trial and quality improvement initiative designed to evaluate the efficacy of electronic provider notification versus usual clinical care in the management of patients with severe aortic stenosis. Providers ordering an echocardiogram with findings potentially indicative of severe aortic stenosis are randomized to receive electronic notification with customized guideline recommendations for the management of severe aortic stenosis or usual care (no notification). Randomization continues until 940 patients are enrolled. SETTING: Multicentered, academic health system. OUTCOMES: The primary endpoint is the proportion of patients with severe aortic stenosis receiving an aortic valve replacement within one year of the index echocardiogram. Secondary endpoints include mortality, heart failure hospitalization, transthoracic echocardiogram utilization, aortic stenosis billing code, and cardiology/Valve Team referral. CONCLUSION: The DETECT AS trial will provide insight into whether electronic notification of providers on the presence of severe aortic stenosis and associated clinical guideline recommendations will facilitate recognition and guideline-directed management of severe aortic stenosis.

The Role of Genetics in Advancing Cardiometabolic Drug Development.

PURPOSE OF REVIEW: The objective of this review is to explore the role of genetics in cardiometabolic drug development. The declining costs of sequencing and the availability of large-scale genomic data have deepened our understanding of cardiometabolic diseases, revolutionizing drug discovery and development methodologies. We highlight four key areas in which genetics is empowering drug development for cardiometabolic disease: (1) identifying drug candidates, (2) anticipating drug target failures, (3) silencing and editing genes, and (4) enriching clinical trials. RECENT FINDINGS: Identifying novel drug targets through genetic discovery studies and the use of genetic variants as indicators of potential drug efficacy and safety have become critical components of cardiometabolic drug discovery. We highlight the successes of genetically-informed therapeutic strategies, such as PCSK9 and ANGPTL3 inhibitors in lipid lowering and the emerging role of polygenic risk scores in improving the efficiency of clinical trials. Additionally, we explore the potential of gene silencing and editing technologies, such as antisense oligonucleotides and small interfering RNA, showcasing their promise in addressing diseases refractory to conventional treatments. In this review, we highlight four use cases that demonstrate the vital role of genetics in cardiometabolic drug development: (1) identifying drug candidates, (2) anticipating drug target failures, (3) silencing and editing genes, and (4) enriching clinical trials. Through these advances, genetics has paved the way to increased efficiency of drug development as well as the discovery of more personalized and effective treatments for cardiometabolic disease.
