Myocardial infarction following convulsive and nonconvulsive seizures.

UNLABELLED: Myocardial infarction (MI) has been rarely reported in association with seizures, and only of convulsive type. METHODS: We describe a series of five patients observed over a 4-year period, who presented MI immediately following seizures, either convulsive or nonconvulsive. RESULTS: Patient 1 had pre-existent coronary disease (CD) and presented multiple focal nonconvulsive seizures. Patient 2 had no CD, normal coronary angiography and presented secondary generalized convulsive seizures. Patient 3 had no history of CD, normal angiography and had a first single convulsive seizure. Patient 4 had severe CD and suffered from a single convulsive event. Patient 5 had a partial and a generalized seizure and had no known CD. CONCLUSIONS: MI following seizures is not an exceptional event and can occur in a spectrum of conditions including single or repeated, convulsive or nonconvulsive seizures, in patients with or without pre-existing coronary disease. We suggest that the occurrence of MI should be considered in epileptic patients during and shortly after seizures.
