Adenosine as a vasodilator in primary pulmonary hypertension.
BACKGROUND The acute administration of vasodilator drugs to patients with primary pulmonary hypertension has been advocated to identify those with reversible pulmonary vasoconstriction. Unfortunately, the usefulness of the drugs currently available is limited by accompanying systemic hypotension. A vasodilator with effects confined to the pulmonary circulation would therefore be advantageous in...
متن کاملEcho/Doppler and hemodynamic correlates of vasodilator responsiveness in primary pulmonary hypertension.
To determine correlates of acute vasodilator responsiveness in primary pulmonary hypertension, we retrospectively studied 25 patients, comparing 41 resting echo/Doppler and nine resting catheterization variables with the maximal reduction in pulmonary vascular resistance achieved during vasodilator trials. Twelve vasodilators were tested (mean, 5.6 drugs per patient; range, three to eight). Eig...
متن کاملProstacyclin and acetylcholine as screening agents for acute pulmonary vasodilator responsiveness in primary pulmonary hypertension.
Epoprostenol sodium (prostacyclin) administered intravenously is considered the standard for assessing the ability of the pulmonary circulation to vasodilate. At present, epoprostenol sodium is an investigational drug that has limited availability. In contrast, acetylcholine, also a pulmonary vasodilator, is readily available. Therefore, we assessed the feasibility of using acetylcholine as an ...
متن کاملEvaluation of Pulmonary Hypertension In First Degree Relatives Of Patients With Primary Pulmonary Hypertension
Background: Pulmonary hypertension (PH) was defined for the first time in 1951 as primary pulmonary hypertension (PPH). Some studies emphasized on the role of genetics in the development of pulmonary hypertension in family members of affected patients. So, in this study we evaluated the prevalence of pulmonary hypertension in first degree family of patients with documented PPH. Methods: In thi...
متن کاملRecent Trends in the Management of Pulmonary Hypertension
Context. Pulmonary hypertension is a common clinical problem encountered in day-to-day practice. Drug therapy forms the backbone of management and appropriate drug selection is based upon the underlying causes. The options available are widening with availability of newer therapeutic agents and thus it becomes necessary to be updated with the recent developments. Objective. To review the existi...
