A Registry Study on Primary/idiopathic Triglyceride Deposit Cardiomyovasculopathy

December 17, 2024 updated by: Translational Research Center for Medical Innovation, Kobe, Hyogo, Japan
The objective of this study is to construct a registry; in order to understand the onset status of triglyceride deposit cardiomyovasculopathy (TGCV) in Japan with patients' background and natural history of the disease, and to explore disease-specific prognostic factors.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Adult patients (excluding under 20 years old) who have been confirmed as TGCV based on the diagnostic criteria for TGCV by a cardiologist.

Description

Inclusion Criteria:

  • Adult patients who have been confirmed as TGCV based on the diagnostic criteria for TGCV

Exclusion Criteria:

  • The patients who refused to participate in the study by opt-out

TGCV
Patients who have been confirmed as TGCV by a cardiologist.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The period between the date of TGCV diagnosis and the date of death due to any cause
Time Frame: 10 years
The period is from the date of diagnosis of TGCV to the date of death due to any cause. Survival and lost follow-up cases will be censored on the final confirmation date of survival.
10 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Comparison of subjective symptoms, laboratory findings, and event occurrence before and after tricaprin therapy: Washout rate of BMIPP (%)
Time Frame: 10 years
10 years
Comparison of subjective symptoms, laboratory findings, and event occurrence before and after tricaprin therapy: LVEF (%) (UCG or QGS)
Time Frame: 10 years
10 years
Comparison of subjective symptoms, laboratory findings, and event occurrence before and after tricaprin therapy: Any cardiovascular events
Time Frame: 10 years
10 years
Presence (date of occurrence or treatment) or absence of various events
Time Frame: 10 years
To measure the period from the date of diagnosis of TGCV to the date the following event occurs: non-fatal myocardial infarction by the outcome assessment, non-fatal stroke, hospitalization for heart failure, CABG, PCI, TVR, pacemaker/ICD implantation, CRT, VAD, acute coronary syndrome requiring hospitalization, hospitalization/device activation/heart transplantation due to fatal arrhythmia. However, surgery scheduled at the time of diagnosis will not be treated as an event.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
