Study summary

The study is designed to establish a comprehensive myocardial energetic phenotype across a broad spectrum of cardiovascular diseases using phosphorus-31 magnetic resonance spectroscopy (31P-MRS).

And the study plans to enroll 1,000 participants, comprising healthy volunteers and patients with diverse cardiac conditions. Target cohorts primarily encompass heart failure syndromes and various cardiomyopathies, with a particular focus on non-ischemic and hypertrophic phenotypes, as well as ischemic and other structural etiologies.

By integrating 31-MRS with multiparametric standard CMR, this study aims to map disease-specific metabolic signatures. The primary outcome measure is the myocardial PCr/ATP ratio, serving as a direct in vivo marker of energetic impairment. Furthermore, the study aims to explore the coupling between metabolic phenotypes and structural remodeling (tissue characterization), mechanical dysfunction, and systemic clinical biomarkers. Crucially, the study will evaluate the prognostic value of these energetic phenotypes in predicting clinical outcomes, ultimately providing novel insights into the pathophysiology and risk stratification of cardiomyopathies and heart failure.

Inclusion criteria

  • Age >= 18 years
  • Healthy volunteers, OR

Exclusion criteria

Exclusion Criteria:

* Any to CMR examination

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Groups and cohorts

  • Healthy controls

    Volunteers without cardiovascular disease undergoing the same CMR and 31P-MRS protocol to establish reference values.

  • Heart failure

    Patients primarily enrolled with a clinical diagnosis of heart failure, comprehensively encompassing preserved (HFpEF) and reduced ejection fraction (HFrEF) phenotypes.

  • Non-ischemic cardiomyopathy

    Patients primarily diagnosed with non-ischemic etiologies, prominently including hypertrophic cardiomyopathy (HCM), as well as amyloid, or inflammatory cardiomyopathies.

  • Ischemic cardiomyopathy

    Patients with cardiomyopathy primarily attributable to coronary artery disease.

  • Other structural heart disease

    Patients with hypertensive heart disease or valvular heart disease.

  • Inherited cardiomyopathy

    Patients with cardiomyopathy attributable to a primary gene mutation related with myocardial energy metabolism.

What researchers measure

Primary outcomes

  1. Myocardial phosphocreatine to ATP ratio (PCr/ATP)

    Myocardial PCr/ATP measured by 31P magnetic resonance spectroscopy

    Time frame: At baseline CMR examination

Secondary outcomes

  1. Composite Cardiovascular and Heart Failure Events

    The composite clinical endpoint includes cardiovascular mortality, heart failure-related events (including hospitalization for heart failure, heart transplantation, or implantation of a mechanical circulatory support device), and documented life-threatening arrhythmias. The components of this composite outcome will be specified according to the specific cardiac disease cohort being evaluated.

    Time frame: Up to 3 years
