Rescue coronary angiography after failed thrombolysis: a real-life experience

Area of Science:

• Cardiology
• Interventional Cardiology
• Acute Myocardial Infarction Management

Background:

• Failed thrombolysis in acute myocardial infarction (AMI) carries significant morbidity and mortality risks.
• The role of rescue or salvage percutaneous transluminal coronary angioplasty (PTCA) after failed thrombolysis remains debated.
• Hemodynamic instability or large myocardial area at risk necessitates prompt intervention in AMI.

Purpose of the Study:

• To evaluate the efficacy and safety of early emergency angiography and rescue PTCA in hemodynamically unstable AMI patients with failed thrombolysis.
• To assess the impact of rescue PTCA on risk stratification and decision-making during the hyperacute phase of AMI.
• To determine the success rate of restoring infarct-related artery patency using rescue PTCA.

Main Methods:

• Retrospective analysis of 27 patients with failed thrombolysis for AMI.
• Inclusion criteria: hemodynamic instability or large myocardium at risk.
• Early emergency angiography followed by rescue PTCA when indicated.

Main Results:

• Rescue PTCA was successful in 95% of attempted procedures.
• Three patients required emergency coronary artery bypass grafting (CABG).
• Early angiography and rescue PTCA facilitated risk stratification and intervention.

Conclusions:

• Early emergency angiography with rescue PTCA is a valuable tool for selected AMI patients with failed thrombolysis.
• This strategy effectively stratifies risk and aids in hyperacute phase decision-making.
• Rescue PTCA demonstrates a high success rate in restoring infarct-related artery patency.
