Myocardial infarction
Pathogenesis
Coronary artery thrombosis
Myocardial necrosis
Nota:
20 to 30 minutes after vessel occlusion
Morphology
Gross
0-12 hrs no change
18-24 hrs slight pallor
24-72 hrs pallor
4-7 days hyperemic rim
10 days yellow, soft, shrunken
7 weeks firm pale scar
Histology
4-12 hrs early coagulative necrosis
18-24 hrs neutrophil infiltrate
24-72 hrs complete coagulative necrosis and heavy neutrophile infiltrate
4-7 days macrophages and early granulation tissue
10 days prominent granulation tissue
7 weeks fibrosis
Clinical features
Severe, crushing, central chest pain
Lasts for hours
Not relieved by nitroglycerine
Silent - elderly, diabetes mellitus
Diagnosis
ECG changes
Q waves
ST segment abnormalities
T wave inversion
Lab evaluation
CK-MB 2 to 4 hrs, peak 18 hrs
Lactate Dehydrogenase 24 hrs, peak 72 hrs
Troponins (T and I)
Complications
Sudden death
Cardiac arrhythmias
Left ventricular failure
Cardiogenic shock
Rupture of free wall, septum, pappilary muscle

Nota:
weeks-few months later pericarditis
Pathogenesis
