Biological variation of 16 biochemical analytes estimated from a large clinicopathologic database of dogs and cats.

Background: Biochemical measurements are commonly evaluated using population-based reference intervals; however, there is a growing trend toward reassessing results with within-subject variation (CV).

Objectives: We aimed to estimate the CV of 16 biochemical analytes using a large database of dogs and cats, which refers to the results of routine health checkups.

Methods: Pairs of sequential results for 16 analytes were extracted from a database of adult patients.

Perioperative changes in cardiac biomarkers in juvenile cats during neutering.

Perioperative myocardial injury (PMI) is commonly caused by myocardial ischemia that develops during or after non-cardiac surgery. It occurs in 17.9% of human patients after non-cardiac surgery due to elevated high-sensitive perioperation cardiac troponin.
