Abstract Background and aims In the present study, we aimed to compare the clinical and coronary angiography features between South Asian and Caucasian patients with Acute Coronary Syndrome (ACS). In particular, we focused our analysis on the evaluation of recent cardiovascular risk markers, such as remnant cholesterol, corresponding to all plasma cholesterol minus HDL-C (high-density lipoprotein cholesterol) and LDL-C (low-density lipoprotein cholesterol), and the Monocyte-to-HDL-cholesterol ratio. We also compared values of several lipoprotein ratios and the Platelet-to-lymphocyte ratio, accurate predictors of coronary events and coronary artery disease. Methods and results We recruited 40 South Asian and 40 Caucasian patients admitted for ACS. Data were collected by consulting patients' medical records. We used Chi-square test and Student's t-test to analyse qualitative and quantitative variables, respectively. South Asian patients, compared to Caucasians, showed higher mean values of the parameters analysed: remnant cholesterol (32.6 ± 17 vs 26.5 ± 9.6), Monocyte-to-HDL-cholesterol ratio (26.4 ± 48.7 vs 16.5 ± 8.3), Platelet-to-lymphocyte ratio (124.7 ± 130.7 vs 120.5 ± 58.8). Moreover, higher mean values of several lipoprotein ratios were also found in South Asian patients compared to the control group. However, statistical significance was not reached for any of these differences observed. Conclusions The evaluation of the parameters analysed in this study might provide accurate information regarding the cardio-metabolic risk in South Asian patients. However, further studies with larger samples are needed to obtain more significant results.
