Plain-English summary
A group of 58 cats with hypertrophic cardiomyopathy (HCM), a heart condition, had their blood tested to measure the neutrophil-to-lymphocyte ratio (NLR), which can indicate health risks. The study found that cats with higher NLR levels were at a significantly greater risk of cardiac death, especially those in the highest NLR group. This means that if your cat has HCM and a high NLR, it could be a sign of worsening heart health. Monitoring this ratio can help veterinarians assess the risk and manage treatment more effectively.

Abstract
OBJECTIVE: To assess the prognostic value of neutrophil-to-lymphocyte ratio (NLR) for cardiac death in cats with hypertrophic cardiomyopathy. STUDY DESIGN: Prospective observation study. ANIMALS: Ninety-six client-owned cats. METHODS: Complete blood count samples were collected from 38 healthy and 58 cats with hypertrophic cardiomyopathy (HCM), and the NLR ratios were analyzed. All cats had echocardiographic measurements performed on the same day as blood collection. Spearman rank correlation was used to assess the relationship between echocardiographic measurements and NLR. Long-term outcome data were obtained, and time to cardiac death and variables associated with cardiac death were analyzed using Kaplan-Meier survival curves and Cox proportional hazards models, respectively. RESULTS: The NLR was significantly higher in cats with confirmed congestive heart failure. When evaluating HCM patients, cats in the third NLR tertile had a significantly higher risk of cardiac death with a hazard ratio of 10.26 (95% CI: 1.84-57.14;= 0.0001) when compared with that of patients in the first tertile. NLR was significantly associated with echocardiographic measures of left atrial size, left auricular function, the presence of left atrial spontaneous echo contrast (SEC), and thrombus formation. CONCLUSIONS AND CLINICAL RELEVANCE: Increased NLR is a negative prognostic indicator in cats with HCM.
