Study Details

Study Description

Brief Summary

This study investigates whether an individualized exercise program, including a personal trainer, can improve cardiovascular status quantified with ultrasound to assess coronary flow reserve and other non-invasive techniques. The subjects in the study will be divided into two groups; one group will have a personalized exercise- and nutrition program and the other group will have acess to a gym membership, but no personal trainer.

Condition or Disease Intervention/Treatment Phase
  • Behavioral: physical exercise
  • Behavioral: limited physical exercise

Detailed Description

Coronary heart disease is one of our most common diseases that causes significant morbidity and mortality. Because the risk of serious cardiovascular events, such as myocardial infarction and death, is evident in this patient population, it is of utmost importance to develop diagnostic methods to identify patients at risk. The most appropriate diagnostic methods are those that are safe to implement for both patient and physician, but also accessible and cost-efficient.

By using non-invasive techniques such as ultrasound, coronary artery function can be examined as coronary flow reserve (CFR). In the platform of non-invasive techniques used by the investigators for examinations of cardiovascular status, other methods are included, such as measurement of intima-media thickness in the carotid and radial arteries. The investigators goal is to compare the group with the personalized program with its placebo, and to compare the two study-groups with each other, to investigate whether the personalized program provides greater health benefits.

  • Outcome Measures

    Primary Outcome Measures

    1. Coronary flow reserve (CFR) [3-6 months]

      Ultrasound-assessed coronary flow reserve. Data will be presented as a ratio (no unit) between maximal mean hyperemia flow velocity and baseline velocity

    Secondary Outcome Measures

    1. endothelial function [3-6 months]

      measured by EndoPath-device as RHI (reactive hyperemic index). Data will be presented as number of patients with abnormal RHI-values

    2. cIMT (carotid artery intima-media thickness) [3-6 months]

      carotid artery intima-media thickness, data will be presented in mm

    3. metabolic biomarkers [3-6 months]

      relevant metabolic blood biomarkers, data will be presented as numbers of participants with values of laboratory analyses below or above reference values

    4. cardiovascular biomarkers [3-6 months]

      relevant cardiovascular blood biomarkers, data will be presented as numbers of participants with values of laboratory analyses below or above reference values

    5. QoL (quality of life) [3-6 months]

      quality of life as measured by the validated scale PGWB (personal general well-being scale). Data will be presented as scores from the scale.
