Diets rich in medium chain fatty acids and antioxidants are a potential means of treatment. A previous clinical study found significantly smaller left atrial diameter (LAD) and left atrium-to-aorta diameter ratio (LA\u2009:\u2009Ao) in dogs with subclinical DMVD fed a specially formulated diet vs control diet for 6\u2009months.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Hypothesis\/Objectives<\/jats:title>\n                    <jats:p>A specially formulated diet will slow or arrest left heart enlargement in dogs with subclinical DMVD over 365\u2009days.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Animals<\/jats:title>\n                    <jats:p>One hundred twenty-seven dogs with unmedicated subclinical DMVD; 101 dogs in the per protocol cohort.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Randomized double-blinded controlled multicenter clinical trial.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The study's primary composite outcome measure was the sum of percentage change in LAD and left ventricular internal dimension at end-diastole (LVIDd) at day 365. In the per protocol cohort, the outcome measure increased by 8.0% (95% confidence interval [CI], 2.9%-13.1%) in dogs receiving the test diet vs 8.8% (95% CI, 5.1%-12.5%) in dogs receiving control diet (P\u2009=\u2009.79). Neither component of the primary outcome measure was significantly different between groups (LAD, P\u2009=\u2009.65; LVIDd, P\u2009=\u2009.92).
