About this trial
This is an interventional prevention trial for Coronary Artery Diseases focused on measuring Coronary artery diseases, Myocardial infarction, Stable angina, Influenza, Vaccine
Eligibility Criteria
Inclusion Criteria:
- Coronary artery disease (CAD) group (CAD-Exp and CAD-Control):
Patients with the diagnosis of acute, evolving or recent MI (after recovered the acute phase) as defined by:
1. Typical rise and gradual fall (troponin) or more rapid rise and fall (CK-MB) of biochemical markers of myocardial necrosis with at least one of the following:
- Ischemic symptoms
- Development of pathologic Qwaves on the ECG
- ECG changes indicative of ischemia (ST segment elevation or depression); OR
- Coronary artery intervention (e.g., coronary angioplasty). 2. Pathologic findings of an acute MI [1]:
- Patients with stable angina pectoris (SA) and documented coronary artery stenosis (angiography).
- Healthy Control group: healthy controls, proportionally matched by gender and age with the patient group (separate control groups for MI and SA patients).
Exclusion Criteria:
- Any acute disease
- Chronic liver or kidney diseases
- Conditions accompanied by immunosuppression (like organ transplantation, HIV)
- Diagnosed malignancy
- Incubation with influenza vaccine within the past 5 years
- Any psychological disease that interferes with regular follow-up
- Congestive heart failure (Killip class IV)
