However, accurate assessment of myocardial function remains challenging. Doppler\u2010derived rate of left ventricular pressure change is a simple, less load\u2010dependent method for evaluating myocardial function. We aimed to evaluate Doppler\u2010derived rate of left ventricular pressure change for assessing myocardial function in different stages of dogs with chronic mitral valve disease. This analytical cross\u2010sectional study recruited 55 client\u2010owned dogs with chronic mitral valve disease prospectively. Based on physical examination, indirectly measured blood pressure, routine hematologic and biochemistry examinations, thoracic radiography, electrocardiography, and echocardiography, dogs were diagnosed as mitral valve disease and excluded for systemic diseases and other cardiac diseases. They were classified according to the International Small Animal Cardiac Health Council scales. Doppler\u2010derived rates of left ventricular pressure rise and fall (dP\/dt and \u2013dP\/dt) were analyzed by two investigators using continuous\u2010wave Doppler imaging. Doppler\u2010derived dP\/dt was higher in dogs of class III<jats:sub>a<\/jats:sub>than in those of the other classes, whereas values of \u2013dP\/dt decreased significantly with the severity of congestive heart failure. The peak velocity of the early diastolic wave and \u2013dP\/dt were identified as independent predictors of congestive heart failure. Our findings suggested that Doppler\u2010derived dP\/dt and \u2013dP\/dt, used in combination with conventional echocardiographic variables, could allow a better understanding of myocardial dysfunction and a possibility for prediction of the risk of heart failure in dogs with chronic mitral valve disease.<\/jats:p>","DOI":"10.1111\/vru.12664","type":"journal-article","created":{"date-parts":[[2018,9,5]],"date-time":"2018-09-05T17:23:45Z","timestamp":1536168225000},"page":"758-766","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Rate
