About this study

Official title: Morbidity and Mortality in Patients Diagnosed With Hypertrophic Cardiomyopathy: a CALIBER Study

The aim of this project is to study the association of a number of demographic and cardiovascular risk factors with death, health care utilisation and systemic embolisation by examining the clinical evolution of hypertrophic cardiomyopathy in a large, community based cohort identified from linked electronic health records.

Read the detailed description

Most data on hypertrophic cardiomyopathy related morbidity and mortality are derived primarily from longitudinal, observational studies based at tertiary cardiac centres. It is unclear what the main causes of morbidity and death are in the general hypertropic cardiomyopathy population (outside tertiary referral centres) and it is likely that many patients have a benign clinical course and die from non-cardiac causes.

Linkage of the Clinical Practice Research Datalink (CPRD) to the Myocardial Ischaemia National Audit Project (MINAP), Hospital Episode Statistics (HES) and Office of National Statistics (ONS), offers the opportunities to study the natural history of hypertrophic cardiomyopathy, from the time of diagnosis to the end of life, health care utilisation and to investigate the association between clinical characteristics and common clinical fatal and non-fatal outcomes.

    Measured: Followed for the duration of general practice registration between date of eligibility and date of administrative censoring, outcome occurrence or death (expected median of 4 years)

  4. Rate ratios for the associations between hypertrophic cardiomyopathy and coronary heart disease not otherwise specified

    Measured: Followed for the duration of general practice registration between date of eligibility and date of administrative censoring, outcome occurrence or death (expected median of 4 years)

  5. Rate ratios for the associations between hypertrophic cardiomyopathy and cardiac arrest

    Measured: Followed for the duration of general practice registration between date of eligibility and date of administrative censoring, outcome occurrence or death (expected median of 4 years)

  6. Rate ratios for the associations between hypertrophic cardiomyopathy and ventricular arrhythmia

    Measured: Followed for the duration of general practice registration between date of eligibility and date of administrative censoring, outcome occurrence or death (expected median of 4 years)

  7. Rate ratios for the associations between hypertrophic cardiomyopathy and atrial fibrillation

    Measured: Followed for the duration of general practice registration between date of eligibility and date of administrative censoring, outcome occurrence or death (expected median of 4 years)

  8. Rate ratios for the associations between hypertrophic cardiomyopathy and heart failure

    Measured: Followed for the duration of general practice registration between date of eligibility and date of administrative censoring, outcome occurrence or death (expected median of 4 years)

  9. Rate ratios for the associations between hypertrophic cardiomyopathy and transient ischemic attack

    Measured: Followed for the duration of general practice registration between date of eligibility and date of administrative censoring, outcome occurrence or death (expected median of 4 years)

  10. Rate ratios for the associations between hypertrophic cardiomyopathy and stroke

    Measured: Followed for the duration of general practice registration between date of eligibility and date of administrative censoring, outcome occurrence or death (expected median of 4 years)

  11. Rate ratios for the associations between hypertrophic cardiomyopathy and peripheral arterial disease

    Measured: Followed for the duration of general practice registration between date of eligibility and date of administrative censoring, outcome occurrence or death (expected median of 4 years)

  12. Rate ratios for the associations between hypertrophic cardiomyopathy and abdominal aortic aneurysm

    Measured: Followed for the duration of general practice registration between date of eligibility and date of administrative censoring, outcome occurrence or death (expected median of 4 years)

  13. Rate ratios for the associations between hypertrophic cardiomyopathy and systemic thromboembolism

    Measured: Followed for the duration of general practice registration between date of eligibility and date of administrative censoring, outcome occurrence or death (expected median of 4 years)

Secondary outcomes (3)
  1. Rate ratios for the associations between hypertrophic cardiomyopathy and cancer

    Measured: Followed for the duration of general practice registration between date of eligibility and date of administrative censoring, outcome occurrence or death (expected median of 4 years)

  2. Rate ratios for the associations between hypertrophic cardiomyopathy and chronic obstructive pulmonary disease

    Measured: Followed for the duration of general practice registration between date of eligibility and date of administrative censoring, outcome occurrence or death (expected median of 4 years)

  3. Rate ratios for the associations between hypertrophic cardiomyopathy and liver-related

    Measured: Followed for the duration of general practice registration between date of eligibility and date of administrative censoring, outcome occurrence or death (expected median of 4 years)

Questions about this trial

What is this clinical trial studying?

An observational study of Hypertrophic Cardiomyopathy, run by University College, London at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 23 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate ratios for the associations between hypertrophic cardiomyopathy and angina (time frame: Followed for the duration of general practice registration between date of eligibility and date of administrative censoring, outcome occurrence or death (expected median of 4 years)). The study lists 13 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Apr 2015.
