Pulmonary Hypertension and Selective Pulmonary Vasodilators in Acute Lung Injury

Vasodilators in pulmonary hypertension.

Statins and Pulmonary Hypertension in Chronic Obstructive Lung Disease

Chronic obstructive lung disease (COPD) is a chronic multisystem disease with a considerable burden. One of its most common complications is pulmonary artery hypertension (PAH). It has been demonstrated that the development of PAH is correlated with decreased quality of life and survival. Different medications have been proposed for the treatment of PAH, among which one can name statins. Howeve...

Two aerosolized nitric oxide adducts as selective pulmonary vasodilators for acute pulmonary hypertension.

STUDY OBJECTIVES To determine the selective vasodilatory effects of two inhaled "NONOate" aerosols in a closed chest pig model of acute pulmonary hypertension (APH). METHODS APH was induced by IV infusion of the prostaglandin H(2)/thromboxane A(2) receptor agonist (U46619). Aerosolized diethylenetriamine nitric oxide (NO) adduct (DETA/NO, n = 4), dipropylenetriamine NO adduct (DPTA/NO, n = 4)...

Pathophysiology of pulmonary hypertension in acute lung injury.

Acute lung injury (ALI) and acute respiratory distress syndrome are characterized by protein rich alveolar edema, reduced lung compliance, and acute severe hypoxemia. A degree of pulmonary hypertension (PH) is also characteristic, higher levels of which are associated with increased morbidity and mortality. The increase in right ventricular (RV) afterload causes RV dysfunction and failure in so...

Pulmonary vasodilators.

Pulmonary vasodilators are an important treatment for pulmonary arterial hypertension. They reduce pulmonary artery pressure; improve hemodynamic function; alter ventilation/perfusion matching in the lungs; and improve functional quality of life, exercise tolerance, and survival in patients with severe pulmonary arterial hypertension. This paper reviews the currently available pulmonary vasodil...
