About this study

The goal of this observational study is to observe the characteristics of cardiopulmonary exercise testing (CPET) parameters in patients across different cardiovascular diseases and to evaluate the predictive value of multiparameter cardiopulmonary indices for 5-year major adverse cardiovascular events (MACE).

Read the detailed description

To investigate the CPET characteristics in patients with various cardiovascular diseases (including acute myocardial infarction, heart failure, cardiomyopathy, valvular heart disease, coronary artery disease, and perioperative cardiac surgery), with annual follow-up of major adverse cardiovascular events (MACE) for five years, and to establish the predictive value of combined CPET parameters for MACE in this population

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Characteristics of CPET parameters across different cardiovascular diseases.

    Cardiopulmonary exercise testing (CPET) was performed using exercise cardiopulmonary testing systems from VYAIRE (Germany) and SCHILLER (Switzerland). A symptom-limited maximal exercise test with a 1-minute ramp incremental protocol (Ramp protocol) was adopted, designed to complete the workload test within 8-12 minutes according to the incremental power calculation formula.

    The incremental workload was calculated as follows:

    Unloaded VO₂ (ml/min) per minute = 150 + (6 × body weight) Predicted peak VO₂max (ml/min) per minute for males = (height in cm - age in years) × 20 Predicted peak VO₂max (ml/min) per minute for females = (height in cm - age in years) × 14 Incremental power per minute = (predicted peak VO₂max - unloaded VO₂)/100

    During exercise, real-time cardiopulmonary parameters were collected, including peak oxygen uptake (VO₂peak), anaerobic threshold (AT), maximal cycling workload, respiratory rate, minute ventilation (VE), and ventilatory efficiency, among others.

    Measured: After enrollment

  2. Incidence of 5-year MACE

    MACE (cardiovascular death, unplanned repeat revascularization, cardiac rehospitalization, non-fatal myocardial infarction, stroke)

    Measured: from enrollment to 5 years post-enrollment

Secondary outcomes (1)
  1. Incidence of individual events of MACE per year (incidence of cardiac death, unplanned rereconstitution, cardiac rehospitalization, nonfatal myocardial infarction, and stroke)

    Measured: yearly for 5 years (Year 1/2/3/4/5 from enrollment)

Questions about this trial

What is this clinical trial studying?

An observational study of MACE and Cardiac Death, run by Guangdong Provincial People's Hospital at 1 site in China.

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 5 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: enrolling by invitation, as of the sponsor's last update on 29 Apr 2026. 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 China. 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?

This study is still under way. Results are not available in the source record yet.

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?

Characteristics of CPET parameters across different cardiovascular diseases. (time frame: After enrollment). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07130968, which also lists 3 linked publications.

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 29 Apr 2026.
