Key Result

Hybrid cardiac telerehabilitation significantly improved functional capacity and perceived health status in patients with non-obstructive hypertrophic cardiomyopathy.

Key Points

This research aims to assess the efficacy and safety of hybrid cardiac telerehabilitation in patients with non-obstructive hypertrophic cardiomyopathy.
Randomized clinical trial design
Participants included low-risk patients with hypertrophic cardiomyopathy
Intervention involved structured telemonitored exercise training
Assessment of functional capacity and perceived health status
Hybrid cardiac telerehabilitation was feasible and safe for participants
Significant improvement in functional capacity observed
Enhanced perceived health status documented among patients

Structured PICO

Does a 12-week hybrid cardiac telerehabilitation program improve peak oxygen uptake in patients with non-obstructive hypertrophic cardiomyopathy and preserved ejection fraction?

Population

60 patients with hypertrophic cardiomyopathy (HCM) without left ventricular outflow tract obstruction (LVOTO), LVEF ≥50%, and an existing implantable cardioverter-defibrillator (ICD). Mean age 51, 48% male. Single-center in Poland.

Intervention

12-week hybrid cardiac telerehabilitation (HCT) program consisting of 1 month hospital-based supervised exercise (interval training on cycloergometer) and 2 months home-based telemonitored exercise (Nordic walking). Training conducted 5 times per week at 60-80% of heart rate reserve.

Comparator

Usual care control group receiving standard outpatient cardiology care and general recommendations regarding healthy lifestyle and activity guidance, without structured training or telemonitoring.

Outcome

Change in peak oxygen uptake (pVO2) after 3 monthssurrogate

Hybrid cardiac telerehabilitation safely and significantly improves functional capacity in low-risk patients with non-obstructive hypertrophic cardiomyopathy.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

HCT is feasible, safe, and effective in improving functional capacity and perceived health status in carefully selected patients with non-obstructive HCM. These findings support the use of structured, telemonitored exercise training in low-risk HCM populations, although larger multicenter trials are needed to confirm generalizability.
