HeartLogic Detects Worsening Heart Failure Due to Patient Non-Compliance

Summary

 
HeartLogic Composite Trend Index Graph

A 30-year-old male with a history of non-compliance to medications was implanted with a Resonate™ family CRT-D, but did not immediately connect the LATITUDE Communicator.

(A) Day 63: A HeartLogic alert occurred on October 30 due to elevated S3 heart sounds, S3/S1 ratio and night heart rate. Thoracic impedance did not detect worsening heart failure symptoms.

(B) Day 69: Six days later, the patient, feeling symptomatic, plugged in his LATITUDE Communicator which transmitted an alert. A phone call with the patient determined the patient was non-compliant with medications; Entresto® was increased and Aldactone® was started.

(C) Day 80: The patient lost seven pounds and reported feeling better.
