Nitroprusside for Prevention of no-Reflow in Primary Angioplasty

Read our disclaimer for details.
In patients admitted with acute myocardial infarction, there is a total occlusion of a coronary artery. Even after emergency catheterization and angioplasty, in some patients, the resumed blood flow is suboptimal and impacts on heart function. The study is aimed at examining whether nitroprusside, an anti-hypertension medication, given directly into the coronary artery, can improve the blood flow after the removal of the obstruction that caused the infarction.
Condition or disease
Inadequate myocardial tissue perfusion despite successful relief of the culprit occlusion and restoration of epicardial coronary flow for ST-segment elevation acute myocardial infarction (STEMI) results in poor outcome. The investigators hypothesized that nitroprusside (NTP) injected intracoronary immediately before angioplasty might prevent no-reflow and improve vessel flow and myocardial perfusion.
