Chen Y, Chai Q, Wang Q, et al. - Researchers conducted the study for exploring the connection between neutrophil-to-lymphocyte ratio (NLR) and coronary microvascular dysfunction (CMD) in type 2 diabetes mellitus (T2DM) patients. The authors reviewed the medical records of 160 T2DM patients and documented their clinical information and laboratory findings. Study participants were divided into CMD group (n = 87) and non-CMD group (n = 73). The NLR value of the CMD group was significantly lower than that of the non-CMD group. Data reported that CMD prevalence in low, medium and high groups were 90%, 61.1%, and 39.2%. The findings revealed that NLR is linked to CMD in T2DM patients and that CMD prevalence may rise as NLR levels fall.
