Answer

Correct answer: c) Arrhythmia

Arrhythmia (particularly ventricular fibrillation) is the leading cause of death in the first 24 hours after myocardial infarction, resulting from electrical instability of ischaemic/injured myocardium. The other listed complications occur later: fibrinous pericarditis typically develops 2–4 days post-MI, papillary muscle rupture causing mitral insufficiency occurs around days 3–7 (period of maximal myocardial softening), and ventricular aneurysm formation is a late complication (weeks to months).
