Concordance of diet with the recommended cholesterol lowering diet in patients with coronary heart disease.
OBJECTIVE
The aim was to examine the concordance of diet with the recommended cholesterol lowering diet in Coronary Heart Disease (CHD) patients receiving usual care.


METHODS
CHD patients were selected for a survey from hospital records at least six months after hospitalization. Four patient groups divided according to the severity of disease were examined in cross-sectional setting. Food records and fatty acid composition of serum lipids were used to assess dietary intake.


METHODS
The study population consisted of 109 patients with coronary bypass grafting, 106 patients with balloon angioplasty, 101 patients with acute myocardial infarction and 99 patients with acute myocardial ischemia.


RESULTS
Concordance of the diet with the cholesterol lowering diet was similar in the patient groups. One third of the patients achieved the recommended fat intake and only one fourth achieved the recommended saturated fat intake. Concordance was better in the patients who also used lipid lowering drugs, but previous myocardial infarction did not affect dietary intake of fat and saturated fat. Diabetic or obese patients tended to have a higher intake of saturated fat. Myristic acid in cholesterol esters, triglycerides and phospholipids and also palmitic and linoleic acids in triglycerides were markers of dietary saturated fat intake.


CONCLUSIONS
Concordance of the diet with the recommended cholesterol lowering diet in CHD patients was moderate. Concordance was not affected by disease severity or previous myocardial infarction and was slightly worse in CHD patients who had diabetes or were obese or did not use lipid lowering drugs.
