NCT00128791
First received: August 9, 2005
Last updated: May 24, 2007
Last verified: May 2007
  Purpose

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.

Primary Outcome Measures:
  • The coronary blood flow in the artery undergoing intervention following angioplasty as determined by the corrected Thrombolysis in Myocardial Infarction (TIMI) frame count (CTFC)
  • Proportion of patients with complete ST-segment resolution immediately after percutaneous coronary intervention (PCI)

Secondary Outcome Measures:
  • The proportion of patients with TIMI grade 3 flow after the procedure
  • The proportion of patients with myocardial grade 3 blush after the procedure
  • The proportion of patients with complete ST-segment resolution at 24 hours post intervention
  • The proportion of patients requiring intra-aortic balloon counter-pulsation and its duration of use
  • Length of hospital stay
  • The combined rate of target vessel revascularization, myocardial infarction or death at 180 days

Estimated Enrollment: 100
Study Start Date: January 2003
Estimated Study Completion Date: April 2005
Detailed Description:

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.
