Among our 1,902 CHD patients, primarily including those with myocardial infarction, ischemic heart disease, and angina, the possible mechanisms contributing to a higher LAR (lactate/albumin ratio) are as follows: In myocardial infarction and patients, insufficient blood supply to the heart prompts myocardial cells to undergo anaerobic metabolism, thus increasing lactate production. Here, ALB is linked to coronary artery disorder.
