Clinical Trial Summary
Heart Failure (HF) is a complex disease associated with the highest burden of cost to the
healthcare system. The cardiopulmonary exercise test (CPET) is instrumental in determining
the prognosis of patients with HF. This study will evaluate whether aggregate biometric data
from the Apple Watch combined with demographic, cardiac, and biomarker testing can improve
our ability to predict heart failure outcomes among a diverse ambulatory HF population
Description:
Heart Failure (HF) has a prevalence of 3.5% suggesting that over one million Canadians are
affected by this disease, and more than 50,000 are newly diagnosed each year. This complex
disease is associated with the highest burden of cost to the healthcare system, attributable
to hospitalizations, missed work, medications, and health care services
Traditionally, clinicians have relied on static snapshots of patients to determine clinical
status and estimate prognosis. More advanced cardiac centers rely on cardiopulmonary exercise
testing (CPET), where patients are further stratified based on validated exercise parameters.
CPET remains underutilized and resource-intensive. It requires expensive equipment,
proficient personnel, and clinicians with specialized training. Thus, there is an unmet need
for a more widely available, accessible, and longitudinal assessment of clinical status to
better monitor and prognosticate patients outside of the ambulatory setting. Wearable devices
such as the Apple Watch hold great promise in this regard, as they provide near-continuous
monitoring of biometric data. By combining biometric data with demographic, cardiac, and
biomarker testing, the investigators will significantly improve our ability to predict heart
failure outcomes such as early warning of decompensation, clinical deterioration (symptoms
and brain natriuretic peptide (BNP) as a surrogate), hospitalization, mortality (using the
Seattle Heart Failure Model (SHFM) as a surrogate), and/or need for advanced heart failure
therapies.
Our study has 5 research questions based on 2 primary outcomes and 3 secondary outcomes in
clinically diverse adult ambulatory heart failure patients :
Primary Research Question:
1. Can biometric data obtained from the Apple Watch be used to estimate cardiorespiratory
fitness, as assessed by CPET?
2. Does the 'predicted' Apple 6 MW estimate correlate with formal 6 MWT?
Secondary Research Questions:
3. Is there a relationship between novel biosensors, including oxygen saturation, and
markers of poor prognosis specifically as defined by the SHFM, BNP, Quality of life
(QOL) indicators, and CPET parameters?
4. Can surrogates of cardiorespiratory fitness obtained from the Apple Watch, including
novel biosensors, predict acute decompensation of heart failure as defined rapid clinic
visits, need for IV diuretics, ED visits, heart failure hospitalization and unscheduled
health care encounters during the 3-month follow-up?
5. Can biometric data be used to improve a risk prediction model that can distinguish
between patients at high versus low risk of all-cause hospitalization (primary outcome),
all-cause mortality (secondary outcome), and a composite outcome of all-cause mortality,
need for ventricular assist device, or heart transplantation (secondary composite
outcome) over a 2 year period?
