In this study, cardiopulmonary exercise will be assessed to characterize the relevance of severity of COPD and coexisting cardiovascular comorbidities for exercise capacity.
Sildenafil is a phosphodiesterase-5 inhibitor that has been approved for the treatment of pulmonary arterial hypertension with orphan drug designation. Sildenafil modulates the nitric oxid...
The investigators believe that iloprost will improve gas exchange in COPD patients with pulmonary hypertension.
The purpose of this study is the evaluation of cardiac and pulmonary response to cardiopulmonary exercise in severe mitral regurgitation and its variation under treatment (surgical mitral ...
Aim #1: Define and determine the prevalence of pulmonary vascular disease and diastolic dysfunction as assessed by the gold standard of invasive hemodynamic cardiopulmonary exercise testin...
Echocardiography can estimate pulmonary arterial pressure (PAP) from tricuspid regurgitation velocity (TRV) or acceleration time (ACT) of pulmonary flow. We assessed the feasibility of TRV and ACT mea...
In lung cancer resection, chronic obstructive pulmonary disease is a risk factor for post-operative complications. Few studies on post-operative complications of lung cancer resection have considered ...
The magnitude of pulmonary hypertension (PH) is extremely important with respect to the intra-operative management of children and infants with an isolated ventricular septal defect (VSD). This study ...
There are limited studies on the effects of asthma on cardiac function. Right ventricular dysfunction and pulmonary hypertension are cardiovascular complications that may be seen in advanced stages of...
This study investigated whether rIPC alters the typical changes in pulmonary arterial pressure, pulmonary gas exchange associated with exercise in hypoxia.
Excessive accumulation of extravascular fluid in the lung, an indication of a serious underlying disease or disorder. Pulmonary edema prevents efficient PULMONARY GAS EXCHANGE in the PULMONARY ALVEOLI, and can be life-threatening.
Echocardiography amplified by the addition of depth to the conventional two-dimensional ECHOCARDIOGRAPHY visualizing only the length and width of the heart. Three-dimensional ultrasound imaging was first described in 1961 but its application to echocardiography did not take place until 1974. (Mayo Clin Proc 1993;68:221-40)
The exchange of OXYGEN and CARBON DIOXIDE between alveolar air and pulmonary capillary blood that occurs across the BLOOD-AIR BARRIER.
Hypertrophy and dilation of the RIGHT VENTRICLE of the heart that is caused by PULMONARY HYPERTENSION. This condition is often associated with pulmonary parenchymal or vascular diseases, such as CHRONIC OBSTRUCTIVE PULMONARY DISEASE and PULMONARY EMBOLISM.
A syndrome characterized by the clinical triad of advanced chronic liver disease, pulmonary vascular dilatations, and reduced arterial oxygenation (HYPOXEMIA) in the absence of intrinsic cardiopulmonary disease. This syndrome is common in the patients with LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL).
