Aminophylline and Contrast Induced Nephropathy in Acute Myocardial Infarction

Opis
Due to the clinical relevance of contrast acute kidney injury a large number of prophylactic procedures have been investigated. N-acetylcysteine and hydration with sodium bicarbonate are proved to be protective against contrast acute kidney injury. The adenosine-mediated afferent arteriolar vasoconstriction is a possible pathomechanism of renal impairment by contrast agent. It has been observed that aminophylline/theophylline, competitive adenosine antagonists, improves oxygen delivery to ischemic tissue, diminishes oxidative damage to renal tissue and may also scavenge free radicals.
The purpose of this study was to investigated whether the additional therapy with adenosine antagonist aminophylline reduces the incidence of contrast renal damage in high risk patients who have acute myocardial infarction.
