Automated Clinical Email Alerts Significantly Increase Life-Saving Valve Replacements in Elderly Patients

Clinicians receiving automated email alerts for aortic stenosis saw treatment rates for patients over 80 rise by nearly 15%, according to new 2026 clinical data.

Addressing the Diagnostic Gap in Aortic Stenosis

Aortic stenosis (AS) remains one of the most critical cardiovascular challenges for the aging population, currently affecting over 2.5 million Americans over the age of 75. The condition, characterized by calcium buildup that restricts blood flow, often presents with symptoms such as fatigue and shortness of breath—signs frequently dismissed by both patients and providers as inevitable aspects of aging. Despite the availability of effective treatments like Transcatheter Aortic Valve Replacement (TAVR), approximately half of all patients with severe symptomatic AS remain untreated. On April 25, 2026, researchers presented late-breaking data in Montreal at the Society for Cardiovascular Angiography & Interventions (SCAI) Scientific Sessions, revealing a digital solution to this persistent clinical oversight.

The DETECT-AS Trial Methodology

The DETECT-AS study was a pragmatic, cluster-randomized trial designed to test the efficacy of Electronic Provider Notifications (EPNs) within a large multicenter health system. The trial monitored 285 healthcare providers managing 939 patients with severe AS, defined by an aortic valve area of ≤1.0 cm². Participants were categorized into three age brackets: under 65, 65–80, and over 80. When a routine transthoracic echocardiography (TTE) detected abnormal results, the system randomly assigned clinicians to either a "usual care" group or an EPN group. The EPN group received automated emails containing summarized management steps and direct links to specialized heart valve teams.

Impact on the Over-80 Demographic

The most profound results were observed in the oldest patient cohort, a group historically at the highest risk for undertreatment. In patients over 80, the rate of aortic valve replacement (AVR) within one year jumped from 26% under usual care to 40.7% when clinicians received an automated alert. This represented a nearly 90% increase in the odds of receiving treatment. For patients between 65 and 80, the treatment rate also saw an improvement, rising to 53.9% compared to 42.6% in the control group. These findings suggest that while younger patients often receive standard care regardless of alerts, the electronic prompt is critical for ensuring older patients are not overlooked by the medical system.
