Lub Dub Lab offers a voice-based AI platform that screens and monitors heart disease through daily smartphone voice interactions. The system analyzes acoustic and breathing features for early signs of cardiac stress, with patients completing routine check-ins via AI phone calls. Their platform includes both a care team dashboard with AI-prioritized alerts and a patient companion app for daily tracking.

Problem
Heart disease remains the leading cause of death worldwide, yet no simple, universal, or scalable screening approach exists. Current evaluation requires multiple complex tests—including blood pressure, cholesterol, ECG, echocardiogram, and coronary calcium scans—making screening fragmented, costly, and inaccessible, especially in underserved communities. Silent heart attacks occur in 1 in 5 patients with no warning symptoms, and specialist shortages further limit access to timely cardiac care.
Solution
Lub Dub Lab provides a voice-based AI platform that transforms everyday smartphone voice interactions into early heart disease screening and monitoring. Patients enroll by establishing a personal voice baseline at discharge, then receive daily automated AI phone calls that capture voice recordings, blood pressure, weight, and wellbeing check-ins. With consent, the platform can also passively analyze acoustic features from everyday calls on WhatsApp and FaceTime, detecting shifts linked to fluid overload and cardiopulmonary stress. Machine learning models score these voice interactions against the patient’s personal baseline in real time, providing care teams with a unified dashboard for monitoring, triaging, and intervening before deterioration leads to hospitalization.
Target Audience
Primary users are hospital care teams, cardiologists, and nursing staff managing heart failure patients post-discharge, as well as healthcare networks serving communities with limited access to specialized cardiac screening.
