Heart Rate Index-An Alternative Exercise-Based Equation for Estimating Peak VO 2.

March 2025
Purpose: Heart rate (HR)-derived variables (HR reserve [HR peak - HR rest ], chronotropic indices [attenuated HR response to exercise], HR recovery [attenuated HR response to exercise recovery], and peak HR index [HR peak /HR rest ]) together with peak oxygen uptake (VO 2peak ) are potential prognostic variables for cardiovascular and all-cause mortality. However, heart rate index (HRI) has not been established as a surrogate for VO 2peak , whether measured (Meas) or estimated (Est), during cycle ergometry (CE) and/or treadmill testing (TT).
Methods: HR-derived prognostic variables to assess cardiovascular outcomes were identified from 150 studies obtained from MEDLINE and Google Scholar searches.
Background: Health-related quality of life (HRQoL) reflects an individual's own perception of their symptom burden, functional limitations, prognosis, overall health and changes associated with treatment. The HeartQoL is a validated heart disease-specific questionnaire with a physical and an emotional subscale that is used internationally to assess HRQoL in patients with coronary heart disease (CHD). The aim of this study was to translate and evaluate the psychometric properties of the HeartQoL in patients with CHD in Iceland.

However, the generalizability of previous meta-analyses of randomized controlled trials (RCTs) is questioned. Therefore, a contemporary updated meta-analysis was undertaken.

Methods: The English version of HeartQoL was translated into Mandarin. A cross-sectional study was then conducted in mainland China using the Mandarin HeartQoL, Short Form-12 Health Survey, and Hospital Anxiety and Depression Scale.

Article Synopsis
- Coronary heart disease (CHD) is a leading global cause of death, and with decreasing mortality rates, more people are living with CHD and need effective symptom management.
- The main focus of the study was to evaluate how exercise-based cardiac rehabilitation (CR) compares to no exercise control in terms of its clinical effectiveness and cost-effectiveness on mortality, morbidity, and health-related quality of life for CHD patients.
- The review incorporated 85 trials with over 23,000 participants, found new evidence supporting exercise-based interventions, and stratified data analysis to better understand outcomes over various follow-up durations.
