Circulating Markers for Ischemic Heart Disease
What this study is about
The purpose of this research is to determine if two proteins in the blood are increased during acute myocardial infarction and whether their levels are higher in those who develop heart failure than those who do not. These two proteins are produced and potentially released when the heart muscle is damaged.
View original scientific description
The purpose of this research is to determine if two proteins in the blood are increased during acute myocardial infarction and whether their levels are higher in those who develop heart failure than those who do not. These two proteins are produced and potentially released when the heart muscle is damaged. They may then be released into the blood and be detected by standard method in the research laboratory. At this time, detection of an increase in these proteins in the blood is not known to be associated with any disease or myocardial infarction.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- men and women, 18 years of age and over with acute myocardial infarction (determined by positive cardiac markers -CKMB/ troponin) with or without heart failure (dyspnea, rales, edema, elevated jugular venous pressure, ascites).
- Heart failure can be diagnosed using imaging evidence such as dilated heart, poor contractile function or echocardiographic Doppler evidence of diastolic dysfunction or elevated right- or left-sided filling pressures
- A control group of male subjects age 60 and older without history of MI or heart disease
Exclusion criteria
- Subjects unable to give consent
- Subjects who have undergone cardiac or non-cardiac surgery in the 3 months prior to enrollment
Where
- Farmington, Connecticut
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
