Why the study?

Most patients with coronary heart disease experience sleep disturbances and low cardiorespiratory fitness, but their relationship during cardiac rehabilitation remains unclear.

What is the relationship between sleep behaviour and cardiorespiratory fitness in patients after percutaneous coronary intervention during cardiac rehabilitation?

Population

101 patients after percutaneous cardiac intervention in Shanghai, China

Design

Longitudinal study protocol

Follow-up

1 year

Overview

Should not yet change practice as results are pending; leaves open whether targeting sleep trajectories improves card.

Structured PICO

What is the relationship between sleep behaviour and cardiorespiratory fitness in patients after percutaneous coronary intervention during cardiac rehabilitation?

P
Population
Target of 101 patients after percutaneous coronary intervention undergoing cardiac rehabilitation at a single center in Shanghai, China.
I
Intervention
Observation of sleep behaviour (actigraphy, Pittsburgh Sleep Quality Index) and cardiorespiratory fitness (cardiopulmonary exercise tests, 6-min walk test) during cardiac rehabilitation.
O
Outcome
Sleep trajectory and the relationship between sleep and cardiorespiratory fitness.surrogate

This protocol outlines a longitudinal study to evaluate the relationship between sleep trajectories and cardiorespiratory fitness in post-PCI patients undergoing cardiac rehabilitation.
