To assess the relationship between the grade of heart failure and blood pressure, 89 healthy dogs and 72 dogs with untreated mitral regurgitation (MR) were compared. Dogs with MR are divided into four groups by NYHA grade. For control, healthy dogs were divided into age-matching four groups. The followings are compared: heart rate, systolic blood pressure, mean arterial pressure and diastolic blood pressure. The results showed that as the NYHA grades rise, so do systolic blood pressure, mean arterial pressure and diastolic blood pressure.
