title: Arachidonic acid level of non-esterified fatty acids and phospholipids in serum and heart muscle of patients with fatal myocardial infarction.
abstract: The relationship between non-esterified fatty acids (NEFA) in serum and heart muscle was examined in 15 patients who died of myocardial infarction (MI) and seven people who died suddenly in accidents. There was no correlation between NEFA levels of serum and non-infarcted cardiac muscle in patients with fatal MI. No significant difference was encountered in cardiac NEFA content between patients with fatal MI and people who died in accidents. The phospholipid (PL) content was significantly lower in patients with fatal MI than observed in people who died in accidents. The arachidonic acid (20:4 (n-6)) concentration of serum NEFA was significantly lower in patients with fatal MI compared to normal subjects. The cardiac NEFA and PL in patients with fatal MI contained significantly lower percentage levels of arachidonic acid compared to people who died in accidents. The results indicate that the death of the MI patients was not accompanied by elevated cardiac NEFA levels.
