NCT ID: NCT03243994 Completed - Clinical trials for Chronic Obstructive Pulmonary Disease

Small Intestinal Absorption in Patients With Chronic Obstructive Pulmonary Disease and Cor Pulmonale

Start date: February 1, 2016
Phase: N/A
Study type: Interventional

Aim: To investigate whether patients with pulmonary hypertension have reduced absorption capacity compared to COPD patients without cor pulmonale potentially due to venous obstruction in the portal vein system. The presence of cor pulmonale was determined by echocardiography. The concentration of D-xylose and zinc were measured in peripheral blood one, two and three hours after ingestion and used as markers of absorption. Furthermore, urine was collected for five hours to determine the amount of excreted D-xylose.

NCT ID: NCT01554774 Completed - Clinical trials for Chronic Obstructive Pulmonary Disease

Non-invasive Assessment of Pulmonary Vascular Resistance in Elderly Patients With Chronic Obstructive Pulmonary Disease

PVR-COPD
Start date: March 2012
Phase: N/A
Study type: Observational

Many studies have evaluated the viability of measuring the pulmonary vascular resistance (PVR) by non-invasive methods in patients with pulmonary hypertension, pulmonary thromboembolism, ischemic cardiopathy and valvular disease. The investigators have not found other studies which evaluate the PVR in elderly patients with COPD. The hypothesis is that in patients with COPD, the severity of obstruction, expressed by GOLD class, is associated with an increase of PVR.

NCT ID: NCT00834145 Not yet recruiting - Right Heart Failure Clinical Trials

Effect of Normatec Pump for Relief of Leg Edema in Patients With Right Heart Failure

Start date: March 2009
Phase: N/A
Study type: Interventional

Mobilization of fluid from the legs with the Normatec pump in patients with right heart failure, may empty the "reservoir" in the legs from excessive fluid, enabling fluid overload to collect there rather than in the liver or in other third spaces. Thus, we hypothesize that patients will lose weight, feel better, look better, be less prone to infections in their legs and to congestion of the liver.
