Elevated RDW has been linked to increased risks of cardiovascular events, including myocardial infarction and stroke.[13,23,24] Similarly, low albumin levels have been identified as predictive of poor cardiovascular outcomes, often reflecting chronic conditions such as heart failure and chronic kidney disease.[15,25,26] In our study, the introduction of RAR revealed a significant positive correlation with CHD, particularly in individuals with higher RAR quartiles. The gene discussed is ALB; the disease is heart failure.
