[Angioplasty compared to thrombolysis as the initial reperfusion therapy in acute myocardial infarction]

Area of Science:

• Cardiology
• Interventional Cardiology
• Acute Myocardial Infarction Management

Background:

• Primary angioplasty is recognized as a superior reperfusion therapy for acute myocardial infarction (AMI) compared to intravenous thrombolysis.
• Effective reperfusion strategies are critical for improving patient outcomes in AMI.

Purpose of the Study:

• To compare the efficacy and safety of primary angioplasty versus thrombolysis for acute myocardial infarction.
• To evaluate outcomes during hospitalization and up to 5 years post-discharge.

Main Methods:

• Historical cohort study utilizing a prospective registry of AMI patients.
• Matched comparison of patients treated with primary angioplasty and those treated with thrombolysis based on age, sex, and event date.
• Clinical outcomes assessed included hospitalization events and 5-year follow-up.

Main Results:

• Primary angioplasty demonstrated a higher success rate (91%) compared to thrombolysis (68%).
• Angioplasty led to fewer complications, reduced in-hospital mortality (2% vs. 11%), fewer revascularization procedures, and shorter hospital stays (13 vs. 17 days).
• No significant differences in adverse events or mortality were observed between groups at 1 or 5 years post-discharge.

Conclusions:

• Primary angioplasty is the preferred reperfusion strategy for acute myocardial infarction, offering superior success rates and reduced in-hospital mortality.
• Long-term patient evolution following acute myocardial infarction appears independent of the initial reperfusion therapy chosen.
