Vasodilator Therapy in Acute Myocardial Infarction
Twenty-six patients with complicated acute myocardial infarction were studied in order to compare the hemodynamic effects of sodium nitroprusside (NP) and nitroglycerin (GTN). All patients received NP and 18 of the 26 also received GTN to evaluate both drugs in the same individuals. Both agents produced significant declines in mean arterial pressure, total peripheral resistance (TPR), and heart...
متن کاملAcute vasodilator testing in idiopathic pulmonary arterial hypertension: must we take NO for the answer?
he earliest clinical descriptions of primary pulmonary hypertension, now known as idiopathic pulmonary arterial hypertension (IPAH), were accompanied by the hypothesis that pulmonary vasoconstriction was one of its key pathophysiological elements [1] and that vasodilators could, therefore, be therapeutically useful. In support of this concept, DRESDALE et al. [2] first reported attenuation of p...
متن کاملVasodilator Therapy in Acute Hemorrhagic Shock.
• Irreversible shock associated with acute blood loss is a serious clinical problem.' Attempts have been made to treat this form of shock with a variety of therapeutic agents including vasopressor drugs, steroids, and plasma expanders. Most popular has been the employment of the vasopressor agents, levarterenol (Levophed) and metaraminol (Aramine), which support blood pressure mainly through an...
متن کاملVasodilator therapy in acute myocardial infarction.
In the context of these studies, the evidence indicates that cardiac performance can improve significantly during vasodilator therapy in acute MI complicated by pump failure. Although the clinical course in uncomplicated patients is good, even without active therapeutic interventions, prognosis in patients with pump failure treated by standard methods (digitalis and diutetics) is discouraging. ...
متن کاملCombined effects of nitric oxide and oxygen during acute pulmonary vasodilator testing.
OBJECTIVES We compared the ability of inhaled nitric oxide (NO), oxygen (O2) and nitric oxide in oxygen (NO+O2) to identify reactive pulmonary vasculature in pulmonary hypertensive patients during acute vasodilator testing at cardiac catheterization. BACKGROUND In patients with pulmonary hypertension, decisions regarding suitability for corrective surgery, transplantation and assessment of lo...
