Trial summary

Major sporting events may have adverse cardiovascular effects in subjects with coronary heart disease. We also hypothesized that the adverse cardiovascular effects of sporting events are a result of psychobiological processes including stress-induced hemodynamic changes, autonomic dysfunction and parasympathetic… Read more about this study

About this study

Official title: Cardiovascular Effects of Major Sporting Events in Subjects With Coronary Heart Disease

Major sporting events may have adverse cardiovascular effects in subjects with coronary heart disease. We also hypothesized that the adverse cardiovascular effects of sporting events are a result of psychobiological processes including stress-induced hemodynamic changes, autonomic dysfunction and parasympathetic withdrawal, and inflammatory and prothrombotic responses, all of which may in turn promote myocardial ischemia.

Read the detailed description

Observational studies suggest that exposure to sporting events may worsen symptoms of angina and trigger acute myocardial infarction. The mechanisms for this association are unknown. To date, there have been no controlled exposures in patients with coronary heart disease: an important population who may be particularly susceptible to the adverse cardiovascular effects of sporting events.

In a randomized crossover controlled study, 38 patients with prior myocardial infarction will be exposed to sporting events or not. Myocardial ischemia will be quantified by ST-segment analysis using continuous 12-lead electrocardiography, and blood pressure change will be analyzed using ambulatory blood pressure monitoring. Autonomic function will be assessed by heart rate variability. Ischemic, inflammatory and prothrombotic markers will also be measured.

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Exposure to sporting events and No exposure to sporting events in people with Coronary Heart Disease, run by Chinese Academy of Medical Sciences, Fuwai Hospital.

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 7 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: finished, as of the sponsor's last update on 6 Aug 2009. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

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

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Evidence of definite myocardial ischemia confirmed by Holter monitoring (time frame: 2 months). The study lists 3 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 6 Aug 2009.
