Heart Failure Sensor Suite
Heart Failure Sensor Suite. How is your heart failure patient’s condition progressing? 

Heart Failure Sensor Suite (HFSS) empowers you to discover meaningful insights into your patient’s condition for better proactive heart failure care.

Heart Failure Sensor Suite enables early detection and proactive Heart Failure care.

Eleri Gregory on heart failure
Eleri Gregory, a Consultant Cardiac Physiologist, explains how HFSS can help to optimize CRT therapy from the start but also to assess the diagnostics and reprogram if necessary.

Heart failure hospitalisations are the most costly aspects of treatment for these patients.1,2

The REM HF study demonstrated that in a typical ICD/CRT-D population with heart failure 40% of cardiovascular hospitalisations were related to heart failure decompensation.3 Heart failure hospitalisations were associated with an 8-fold increase in mortality and a 9-fold increase in recurrent hospitalisations.4 

Symptoms can vary in presentation and over time, nevertheless several patterns may precede a decompensation.

Heart Failure Sensor Suite technology

Heart Failure Sensor Suite is an extensive set of diagnostic sensors made available for an optimal treatment of your patients complementary to the device optimisation with SmartCRT™ Technology.
Our Boston Scientific devices offer you the possibility to access information on the following physiologic trends from LATITUDE™ Patient Management system. All collected data are available from the Heart Failure Management Report on LATITUDE.
Have you ever asked your patient the following questions?:
Our Sensors What clinicians ask/do during a physical examination
Sleep Incline "How many pillows do you sleep on at night?"
Respiratory Rate "Are you out of breath/have difficulty breathing?"
Activity Level "Have you been feeling tired?"
Weight "Have you gained weight?" (check leg or abdominal swelling)
Blood Pressure Measure blood pressure (hypertensive? hypotensive?)

Physiological trends

The Heart Failure Sensor Suite has multiple sensors to track physiological trends that provide insight into a patient’s condition.

Sleep incline – First of its kind

Sleep sensor provides physicians with a posture-based physiological indicator for heart failure decompensation. Sleep incline is the angle between the patient’s torso and the horizontal plane during the night. 0º – laying flat 90º – upright.
Data from MultiSENSE demonstrated that sleep incline reflected common posture-related HF symptoms of orthopnea and paroxysmal nocturnal dyspnea (PND). Thus higher angles could be a sign of worsening HF.5
When Sleep Incline measurement exceeded 14.8 degrees there was a two in three chance that the patient was experiencing symptoms of orthopnea or PND. If the measurement was below 14.8 degrees, there was nearly a nine in ten chance that the patient was not experiencing symptoms of orthopnea or PND.6

Respiration rate – unique feature

Worsening heart failure may be associated with a variability in respiration rate

  • The Respiratory Sensor uses transthoracic impedance measurements to collect respiration-related data, specifically respiration rate and tidal volume.
  • Respiration rate and tidal volume are combined to produce additional respiration metrics.


MultiSENSE data: six months shown

Respiratory rate increased prior to heart failure events7
Respiratory rate above 20 breaths/min on average over 30 days has 3.5 fold increased risk of HF hospitalisation within the following 30 days.8
Respiratory rate with a higher range over 30 days has 4.9 fold increased risk of HF hospitalisation within the following 30 days.9
