This study is a prospective cohort study aimed at exploring the baseline characteristics and treatment patterns of the Chinese population with hypertrophic cardiomyopathy (HCM) in real-world settings. The objective is to assess the real-world treatment approaches and longitudinal outcomes in this population.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients with hypertrophic cardiomyopathy

Description

Inclusion Criteria:

  1. Willing and able to provide written informed consent (ICF) and any required privacy authorization before the start of the study.
  2. Aged ≥18 years at the time of signing the written informed consent.

  3. Diagnosed with hypertrophic cardiomyopathy (HCM) according to the 2023 Guideline for Diagnosis and Treatment of Patients With Hypertrophic Cardiomyopathy, meeting the following criteria:

    1. Left ventricular wall thickness ≥15 mm in any segment at end-diastole, as assessed by echocardiography or cardiac magnetic resonance imaging (MRI).
    2. Left ventricular wall thickness ≥13 mm in individuals with a positive pathogenic gene test or those identified as members of a genetically affected family.
    3. Exclusion of other cardiovascular diseases or systemic/metabolic diseases causing ventricular wall thickening.

Exclusion Criteria:

  1. Uncontrolled primary hypertension.
  2. Moderate or severe aortic valve stenosis and/or primary mitral valve disease with severe mitral regurgitation.
  3. Confirmed infiltrative or storage diseases with a phenotype resembling hypertrophic cardiomyopathy (e.g., Fabry disease, amyloidosis).
  4. Expected life expectancy <1 years.
  5. Severe infections, liver failure, renal failure, or other life-threatening conditions.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
HCM
Patients diagnosed with hypertrophic cardiomyopathy (HCM) according to the 2023 Guideline for Diagnosis and Treatment of Patients With Hypertrophic Cardiomyopathy were consecutively enrolled. These patients received pharmacological, interventional, or surgical treatment based on real-world treatment strategies. Follow-up was conducted to observe patient prognosis and the occurrence of outcome events.
Other: No interventions were applied to the patients.
No interventions were applied to the patients.

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
Composite Cardiovascular Endpoints
Time Frame: 5 years
Number of Participants with a composite cardiovascular endpoint consisting of ischemic stroke, heart failure hospitalization, and cardiovascular death
5 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.
