\n\nMethods: Correlation among BVD-523 purchase plasma ANP, LA size, and cardiac function was prospectively analyzed by Doppler echocardiography in 32 PD patients in Juntendo University Hospital, Tokyo. Measurement of these parameters was performed at 0, 6, 12, 18, and 24 months after start of PD. All patients were treated with an angiotensin type 1 receptor blocker to control blood pressure to less than 140/90 mmHg. Other antihypertensive drugs such as diuretics and/or calcium channel blockers were added if blood pressure rose to over 140/90 mmHg. Hemoglobin and hematocrit levels were targeted at 10.0

g/dL and 30.0% respectively with recombinant human erythropoietin treatment. A diuretic was added or patients decreased their water intake if ANP was more than 43.0 pg/mL or LA diameter (LAD) more than 39 mm, and

for other basic markers of volume status. Cardiac function was measured before and after drainage of PD fluid to evaluate the influence of cardiac function.\n\nResults: LAD at start of dialysis (36 +/- 4.6 mm) decreased significantly to 33 +/- 3.3 mm (p < 0.05), 33 +/- 3.2 mm (p < 0.05), and 33 +/- 3.6 mm (p < 0.05) after 6, 12, and 24 months, respectively. Ejection fraction after 6 months was significantly increased compared with that at start of dialysis (p < 0.05). Left ventricular mass index (LVMI) after 6, 12, and 24 months was significantly decreased compared with that at start of dialysis (p < 0.05). ANP was 56 learn more +/- 39 pg/mL at start of dialysis and decreased

significantly to 33 +/- 19 pg/mL after 24 months (p < 0.05). ANP was significantly correlated with LAD (r = 0.412, p < 0.01), transmitral A wave flow velocity (r = 0.429, p < 0.01), and LVMI (r = 0.426, p < 0.01). CH5183284 cost Instillation of the dialysis fluid did not affect any parameters except inferior vena cava dimension.\n\nConclusion: This study demonstrates a reduction in LA size and LVMI in PD patients followed over 24 months. Left ventricular structure, contraction, and compliance were well preserved in PD patients undergoing aggressive treatment based on measurements of plasma ANP and LAD.”
“Objective – To determine the diagnostic ability of blood N-terminal pro B-type natriuretic peptide (NT-proBNP) measurement to differentiate between congestive heart failure (CHF) and noncardiogenic causes for moderate to severe pleural effusion in cats.\n\nDesign – Prospective observational study.\n\nSetting – University teaching hospital.\n\nAnimals – Twenty-one cats with moderate to severe pleural effusion.\n\nInterventions – Venous blood sampling for NT-proBNP measurement.\n\nMeasurement and Results – According to the results of echocardiographic examination, cats were classified in a group with CHF (n = 11) or noncongestive heart failure (N-CHF, n = 10). NT-proBNP was measured via a feline-specific test in EDTA plasma with protease inhibitor.
