Myocardial Infarction, Body Mass Index, Remnant Cholesterol Index


Background: Remnant cholesterol is not only a link in the chain between obesity and ischemic heart disease, but also a direct contributor to the risk of cardiovascular illness. Remaining cholesterol's potential to increase cardiovascular risk is gaining attention. Although observational and genetic data suggests that higher levels of residual cholesterol in triglyceride-rich lipoproteins are associated with an increased risk of ischemic heart disease, direct measurements have not been able to determine what proportion of plasma cholesterol is present in remnant particles. The focus of this study is to determine whether there is a correlation between body mass index and the quantity of cholesterol in the body after a heart attack.

Methodology: The study was conducted at Department of Cardiology, Punjab Institute of Cardiology, Lahore from October 20, 2020 to April 20, 2021. Total 100 patients with myocardial infarction were enrolled in the study. Blood samples were taken through a disposable syringe under aseptic measures. Then all the samples were sent to the laboratory of the hospital for assessment of cholesterol level. Reports were assessed and remnant cholesterol was calculated. All patients were assessed of BMI i.e. height and weight were measured with the help of a staff nurse. The information was put into SPSS v25.0 for statistical analysis. The association between body mass index and residual cholesterol was determined using Pearson's correlation coefficient. The cutoff for significance was set at 0.05.

Results: Total 100 patients with myocardial infarction were enrolled in the study. Gender distribution showed that 67(67.0%) were males while 33(33.0%) were females. The mean age of the patients was 50.53±14.90 years. The mean BMI of the patients was 29.83±4.33 kg/m2 and remnant cholesterol index as 40.07±11.99 mg/dl. There was a positive correlation between remnant cholesterol and body mass index with a Karl Pearson correlation coefficient of 0.654 with p-value 0.00001.

Conclusion: Myocardial infarction risk is increased across the board when residual cholesterol is high, regardless of body mass index. This data implies that even in lean individuals, remnant cholesterol poses a risk for myocardial infarction. There is a favourable relationship between BMI and residual cholesterol.
