Clinical case

Jasmine, followed at home for a year: from stage B2 mitral valve disease to heart failure

A real case, followed with the Biotracker and the Biotrack platform from June 2024 to June 2025: two automatic alerts, cardiac then respiratory, before the classic 30/min threshold.

Stage C

degenerative mitral valve disease (ACVIM), with congestive heart failure · pulmonary edema

  • June 2024, aged almost 10: degenerative mitral valve disease, stage B2. She is fitted with a Biotracker: from then on her resting heart and respiratory rates are measured at home, automatically.
  • December 2024: echocardiography shows worsening, with chordal rupture; a diuretic is added.

The clinical question: how do you see Jasmine's decompensation coming before her respiratory rate reaches 30/min, without multiplying consultations?

The challenge: monitoring a chronic disease between two visits

For Jasmine, as for every cardiac patient, conventional follow-up has blind spots.

3–6 months

between two spot checks in conventional follow-up, and nothing measured in between

Several times a day

resting heart and respiratory rate recorded at home by the Biotracker, with nothing for the pet parent to do

Conventional follow-up

  • Spot checks every 3 to 6 months.
  • Relies on what the pet parent notices at home.
  • Resting tachypnea, a recognized early sign of decompensation, is hard to objectify by eye.
  • The risk: discovering the deterioration in an emergency, rather than at a planned consultation.

With a connected health device: a Biotracker

  • Resting heart and respiratory rate measured at home, automatically, several times a day.
  • Objective trends, compared with Jasmine's own values.
  • Automatic alerts as soon as a significant deviation appears.
  • The veterinarian follows and acts on an early signal, before the emergency.

From the patient's Biotrack view, 27 June 2024 to 10 June 2025. Vertical lines: chordal rupture and diuretic (4 Dec 2024), RR at 30/min (27 Apr 2025), torasemide doubled (9 May).

  • Her average resting heart rate goes from about 76 bpm in summer 2024 to 90 in December, with the chordal rupture, then to above 110 in early April 2025.
  • ① 5 April: heart rate has gained 12 bpm in 40 days, since 24 February. First automatic alert (red area).
  • ② 17 April: respiratory rate, steady at 14–16/min all winter, has gained 5/min in 20 days. Second alert, at 20.5/min, far from 30.
  • ③ 27 April: respiratory rate crosses 30/min, the classic heart-failure threshold, 22 days after the HR alert, 10 after the RR alert.

    The cardiac alert

    Heart rate has gained 12 bpm in 40 days, from 96 to 111 bpm: Biotrack raises an automatic alert, 22 days before the classic threshold.

  2. 217 Apr 2025

    The respiratory alert

    Respiratory rate has gained 5/min in 20 days: 20.5/min, nothing visible at home. Second alert, 10 days before the threshold.

  3. 327 Apr 2025

    The classic threshold

    Respiratory rate reaches 30/min, the classic criterion for congestive heart failure. On 9 May, torasemide is doubled; by early June, respiratory rate is back below 20/min.

The Jasmine case, on video

The weeks before a cardiac decompensation leave a trace in the vital signs. We follow it here, curve after curve, up to the alert.

On 17 April 2025, in the clinic's dashboard

Her readings of the day, against her values at the start of follow-up. No one watches the curves all day: the alert says which patient to open.

116 bpm

resting heart rate, against 76 bpm on average in summer 2024

20.5/min

resting respiratory rate, against 14/min on average in summer 2024

2 alerts

HR on 5 April, RR on 17 April: her respiratory rate is still far from 30/min

  • Her readings are read against her own baseline and the published reference values by age, weight and breed (AI-COLLAR, ~1,000 dogs).
  • A sustained deviation raises an alert, sorted by AI: the team looks when it is called, not every day.
  • What it allows: bring the consultation forward, or adjust pimobendan and diuretic remotely, without waiting for the next appointment.

Seen coming, not discovered in an emergency

Three things a year of follow-up shows, each one read on the curves, not assumed.

An early signal

Heart rate raised the alert on 5 April, respiratory rate on 17 April: 22 and 10 days before respiratory rate reached 30/min, the classic threshold.

A treatment evaluated

Torasemide doubled on 9 May shows on the curves: respiratory rate back below 20/min by early June, heart rate toward 100 bpm.

A stronger bond

The pet parent understands their dog's disease, with data to back it, and stays engaged with the clinic throughout the follow-up.

For the clinic, this is a billable act: chronic cardiac follow-up, for example €50 to €100 a month billed to the pet parent, renewable for as long as the dog is followed. Each clinic sets the price and the duration.

The same follow-up, in a study

What Jasmine shows for one patient, a laboratory can measure across a whole cohort: resting vital signs at home, every day, from enrollment to the end of the study.
