Active clinical trials for "Hypertension, Pulmonary"

Trouble breathing (dyspnea) is a nonspecific symptom associated with many diseases such as chronic obstructive pulmonary disease (lung disorder in which the flow of air to the lungs is blocked), asthma, pneumonia, pulmonary hypertension (high blood pressure in the lungs), congestive heart failure (fluid build-up in the lungs because the heart is not pumping normally) and pulmonary embolism (blood clot in the lungs). The purpose of this study is to test two blood markers called ST2 and IL-33. Blood markers are proteins or other compounds in your blood that physicians use to diagnose different diseases and to determine what the course of an illness will be. In preliminary research studies, ST2 and IL-33 have been elevated in patients with a wide variety of diseases where the lungs are the primary organs involved. This research study will further investigate the ability of ST2 and IL-33 to predict the severity of disease and the possible use of ST2 and IL-33 in the diagnosis of various lung diseases.

This study investigated clinical parameters, laboratory data, imaging studies to evaluate patients with suspected pulmonary hypertension.

Left heart disease is the main cause of pulmonary hypertension. With the advent of the aging society, chronic heart failure has become a global public health problem. Therefore the prevalence of pulmonary hypertension due to the left heart disease is increasing. However, there is no research on the prevalence of pulmonary hypertension due to the left heart disease in China. Therefore, the aim of the present study was to describe real-world outcome of Chinese patients with pulmonary hypertension due to the left heart disease and identify factors that may predict outcome. Our study will profile the demographics, clinical course, treatments, and outcomes of pulmonary hypertension due to the left heart disease in China.

As a pulmonary hypertension center, we have created a database that prospectively tracks patients with different forms of secondary pulmonary hypertension. Records include genetic analysis, and clinical and hemodynamic profiles.
