Abstract
Objective: To study the
association of cholesterol level and dietary habits in patients of ischemic
heart disease admitted with acute coronary syndromes.
Materials and Methods: A
total of 404 patients of ischemic heart disease admitted at the Punjab Institute
of Cardiology, Lahore were included in the study. Patients were divided into
four groups. Group I: 176(45.5%) patients with normal cholesterol levels and
low fat diet. Group II: 76(18.2%) patients with normal cholesterol levels on
high fat diet. Group III: 113(27.9%) patients with high cholesterol levels on
low fat diet. Group IV: 39(9.6%) patients with high cholesterol levels on high
fat diet. Results: Mean age of the study population was 55.6 ± 12.3 years. Mean
age was similar in all the groups (p< 0.127). Overall 308(76.2%) patients
were males and 96(23.8%) were females. Mean caloric intake of the study
patients was 2570.5 ± 936.7. Caloric intake was highest in Group I followed by
Group III. Group II and IV had lower caloric intake than groups I and III
(p< 0.0001). Similarly percent fat was also lower in Group I and III as
compared to Groups II and IV (p< 0.0001) irrespective of dietary intake of
fat. Low HDL in Group I and II patients even having normal cholesterol level
lead to acute myocardial infarction.
Conclusion: Dietary intake
of fat has no influence on cholesterol levels. Low HDL is an important risk
factor leading to acute myocardial infarction and is not influenced by fat
intake in diet.
