    Summary

    Early postinfarction angina after acute myocardial infarction indicates high risk. Prompt angiographic evaluation and surgical intervention significantly reduce operative mortality and complications.

    Area of Science:

    • Cardiology
    • Cardiovascular Surgery

    Background:

    • Early postinfarction angina following acute myocardial infarction signifies a high-risk patient group.
    • These patients often develop complications such as reinfarction and cardiogenic shock.

    Purpose of the Study:

    • To evaluate the impact of delayed diagnosis and treatment on outcomes in patients with early postinfarction angina.
    • To emphasize the need for prompt angiographic assessment and surgical intervention.

    Main Methods:

    • Retrospective analysis of 38 patients hospitalized for acute myocardial infarction with early postinfarction angina.
    • Assessment of time intervals from angina recurrence to angiographic evaluation and surgical intervention.
    • Comparison of operative mortality rates based on the timing of intervention.

    Main Results:

    • Delayed angiographic evaluation (over 48 hours) was associated with a substantial increase in operative mortality (27.2%).
    • Zero operative mortality was observed when coronary angiography and surgery were performed within 24 hours of angina recurrence.
    • Complications included reinfarction (10 patients), cardiogenic shock (6 patients), and need for intra-aortic balloon pump (12 patients).

    Conclusions:

    • Physicians must recognize early postinfarction angina as a critical warning sign.
    • Prompt angiographic evaluation and timely surgical intervention are crucial to improve outcomes and reduce mortality in this high-risk group.
    • Delaying intervention, often due to trial of medical therapy, significantly increases patient risk.
