Brief Summary

The AGNES case-control set consists of individuals with a first acute ST-elevation myocardial infarction. AGNES cases have ECG- registered ventricular fibrillation occurring before reperfusion therapy for an acute and first ST-elevation myocardial infarction. AGNES controls are individuals with a first acute ST-elevation myocardial infarction but without ventricular fibrillation. All cases and controls are recruited at seven heart centers in The Netherlands. The investigators' exclude individuals with an actual non-ST-elevation myocardial infarction, prior myocardial infarction, congenital heart defects, known structural heart disease, severe comorbidity, electrolyte disturbances, trauma at presentation, recent surgery, previous coronary artery bypass graft or use of class I and III antiarrhythmic drugs. Individuals who develop ventricular fibrillation during or after percutaneous coronary intervention are not eligible. Furthermore, because early reperfusion limits the opportunity of developing ventricular fibrillation, potential control subjects undergoing percutaneous coronary intervention within 2 h after onset of myocardial ischemia symptoms were not included. This time interval is based on the observation that \>90% of cases develop ventricular fibrillation within 2 h after onset of the complaint of symptoms.

Outcome Measures

Primary Outcomes (1)

  • Differences in genetic and inflammatory profile between cases and controls.

    Differences in genetic profile and inflammatory profile between cases and controls are investigated between the complete cohorts.

    Immediately upon admission, measures are based on samples taken at admission.

Secondary Outcomes (1)

  • Differences in clinical characteristics between cases and controls

    Immediately upon admission, measures are based on status at hospital admission.

Other Outcomes (1)

  • Previously described risk factors

    Immediately upon admission, measures are based on status at hospital admission.

Study Arms (2)

AGNES Controls

AGNES controls are individuals with a first acute ST-elevation myocardial infarction but without ventricular fibrillation.

AGNES cases

AGNES cases have ECG- registered ventricular fibrillation occurring before reperfusion therapy for an acute and first ST-elevation myocardial infarction.

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Cases are patients with a first ST-elevation myocardial infarction (STEMI) referred for primary percutaneous intervention (PCI), who develop ventricular fibrillation between the onset of acute myocardial infarction (chest pain, ECG changes) and reperfusion. Reperfusion can either be spontaneous or by PCI. Control patients are patients with a first STEMI, referred for PCI who do not develop ventricular fibrillation.

You may qualify if:

  • First ST elevation myocardial infarction (STEMI)
  • Between 18 and 80 years old

You may not qualify if:

  • A grandparent from non-European descent
  • Inborn errors; congenital heart defects.
  • Prior myocardial infarction (either STEMI or non-STEMI)
  • Previous CABG (coronary artery bypass graft)
  • Use of anti-arrhythmic drugs with the exception of beta-blockers, Ca2+-antagonists and lanoxin.
  • Severe current co morbidity (electrolyte disturbances, K+\>5.5, K+\<3.0 mmol/L, anaemia, trauma, surgery).
