Journal Title: Journal of Medical Science And clinical Research - Year 2017, Vol 5, Issue 11
Abstract
Worldwide studies have reported increase in the incidence of CAD in illiterate & people with lower socio economic status1 . Based on cross sectional morbidity surveys incidence of coronary heart disease has increased two fold, (2.06% is 1970’s to 4.04% in 1990’s) in rural India3 . There is no published data correlating dietary pattern & risk factors in patient with CAD in rural Tamil Nadu. Aim: Correlation of dietary pattern and risk factors in patient with CAD in rural Tamil Nadu. Study Design: Retrospective case control study. All patients residing in rural areas who underwent CAG in our centre with evidence of CAD were enrolled for the study after informed consent. Methodology: All the patients with CAD were interviewed by the dietician of our hospital regarding their diet pattern, using a 7days dietary recall questionnaire. This was analysed & daily intake fat, carbohydrates, protein & total calories of each patient was tabulated & compared with recommended dietary allowance 2010 guidelines for Indian (ICMR). Results: A total of 148 patients who underwent CAG 39.9% (59 patients) had normal CAG, 29.1% (43 patients) had SVD, 17.6% (26 patients) had DVD and 13.5% (20 patients) had TVD. Male & Female patients were equally distributed in CAD & normal group (P=0.24). Patients with Hypertension (OR 1.4, 95% CI: 0.6 – 2.9), Diabetes (OR 1.85, 95% CI: 0.91 – 3.71) tended to have CAD, however it did not reach statistical significance. The mean intake of carbohydrates, protein, and fat did not reach statistically significance between the 2 groups. There was a significant difference in carbohydrate intake in patients with single vessel disease, but did not reach statistical significance in patients with double / triple vessel disease when compared with normal coronaries. Conclusion: Risk of CAD in rural population of Tamil Nadu is not related to total carbohydrates or fat intake. Coronary artery disease could be related poor intake of vegetables and fruits.
