JOURNAL FREE ACCESSA 13-year-old female Beagles dog was referred with a history of abdominal enlargement and dyspnea. Thoracic radiograph revealed cardiac enlargement. Echocardiograph revealed tricuspid valve regurgitation. Although right atrial pressure was normal, right ventricular pressure was elevated (systolic/end-diastolic; 69/5.0 mmHg). Similarly, although plasma ANP was normal, plasma NT-proBNP was elevated to 1,583 pmol/L. The following medications were prescribed: enalapril, torasemide, and methyldigoxin. After 30 days of treatment, clinical signs and right ventricular pressure was decreased (20/-2.3 mmHg). The plasma NT-proBNP had decreased to 1,245 pmol/ml. These results suggest that elevated right ventricular pressure induced in an increase in plasma NT-proBNP levels.View full abstractDownload PDF (484K) -

JOURNAL FREE ACCESSA 4-month-old dog with patent ductus arteriosus was suspected with severe pulmonary hypertension and consequently, surgical ligation was performed. Preoperative echocardiography did not show a left to right shunt; hence, development of pulmonary hypertension was suspected. After the surgery, the dog developed syncope and thoracic radiography and echocardiography findings worsened; this led us to suspect progression of pulmonary hypertension and right-side heart failure. One month later, thoracic radiography and echocardiography findings improved and the symptom on exertion disappeared. The present case suggests surgical closure as a treatment option in dogs with patent ductus arteriosus suspected pulmonary hypertension.View full abstractDownload PDF (698K) -

JOURNAL FREE ACCESSA 7-year-old male cat was referred with a history of sudden dragging of the limbs the previous night. A physical examination revealed open-mouth breathing, cold paraplegic rear limbs, and no palpable femoral pulse. An echocardiograph indicated left ventricular wall thickening, a reduced left ventricular cavity, and left atrial enlargement. The cat showed elevated plasma concentrations of aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), and creatine phosphokinase (CPK). Plasma atrial natriuretic peptide (ANP) level was also elevated to 95.5 pg/ml. The cat received intensive care for 3 days and medications were continued after discharge. After 28 days of treatment, clinical signs and echocardiographic findings improved. The plasma chemistry showed a decrease in AST, ALT, LDH, and CPK levels, and plasma ANP level had decreased to 38.8 pg/ml. These results indicate that serial measurement of plasma ANP levels may be used to monitor the effectiveness of therapies chosen to treat conditions such as left ventricular hypertrophy.View full abstractDownload PDF (484K)
