The Harefield Acute Myocardial Infarction Cohort (HEART - ACS)

January 13, 2020 updated by: Royal Brompton & Harefield NHS Foundation Trust
In this project the investigator's plan to collect blood during a patient's routine angiogram procedure which they will have due to having suffered a heart attack. Data from the patients' routine procedures for this condition, including but not exclusively, ECG, Echocardiogram, MRI scans, will be collected. The aim of the research project is to analyse the blood samples and identify novel biomarkers and clinical parameters associated with acute coronary syndromes. The investigator's will particularly focus on markers of inflammation and micro-organism activity. The investigator's hope that this will help to gain more knowledge about what causes heart disease and how various conditions can be treated more efficiently. The investigator's will follow-up and collect further research data via a questionnaire at the routine 6 weeks and 6 months follow-up appointment after the angiogram procedure. Participants will also be telephoned at one-year post procedure, to update any events and medication status and data will thereafter be collected form data held by the hospital without having to contact the participant. Remaining blood samples will be stored securely for further analysis into blood and other markers.

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Acute coronary syndromes (ACS), i.e. patients presenting with ST-segment elevation myocardial infarction (STEMI), non ST-segment elevation myocardial infarction (non-STEMI) or unstable angina, are still a major cause of morbidity and mortality in the United Kingdom and beyond. In spite of the enormous progress made in the last decades, the in hospital mortality has plateaued recently, and the event rate after the infarction is still high with one in 8 patients having a second event (i.e. death, myocardial infarction, heart failure, revascularization among others) within a year of follow-up.

After the acute event, risk stratification is important and will be come even more sophisticated than it currently is with the advent of anatomic risk scores (SYNTAX II Score), novel biomarkers and novel drugs allowing for more precise characterization of the patients individual risk and more tailored secondary prevention strategies (Precision Medicine).

Indeed, particularly the upcoming treatment strategies with bio-logicals (i.e. monoclonal antibodies, e.g. against PCSK9) and genetic tools (i.e. RNA interference, antisense technology) will require precise risk assessment for cost-effective use of these promising new tools.

It is anticipated that this study will help the investigator's to describe the heart attack population in a robust manner with a wealth of clinical data as well as blood samples for bio-markers.

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

  • Child
  • Adult
  • Older Adult

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

Acute Coronary Syndrome - Iscaemia
Patients who present with chest pain, undergo emergency angiogram and receive a cardiac stent.
Other: 60mls of blood donated for research analysis
All patients presenting with a possible Acute Coronary Syndrome will be invited to donate 60 mls of blood at the time of their angiogram.

Patients who present with chest pain but angiography reveals normal coronary arteries.
Other: 60mls of blood donated for research analysis
All patients presenting with a possible Acute Coronary Syndrome will be invited to donate 60 mls of blood at the time of their angiogram.

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.

Measure Description
Time Frame
To identify novel biomarkers and clinical parameters associated with acute coronary syndromes caused by coronary artery disease
Time Frame: 2 - 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.
