Prognosis in unstable angina.

M K Heng, R M Norris, B M Singh

    British Heart Journal
    |September 1, 1976
    PubMed
    Summary

    Unstable angina patients face risks of in-hospital myocardial infarction and death. Older age, cardiomegaly, and pulmonary congestion increase long-term mortality risk in these cardiac patients.

    Area of Science:

    • Cardiology
    • Internal Medicine

    Background:

    • Unstable angina is a critical condition requiring prompt management in a coronary care unit.
    • Understanding short-term and long-term outcomes is crucial for patient care and prognosis.

    Purpose of the Study:

    • To analyze the in-hospital and long-term outcomes of patients admitted with unstable angina.
    • To identify predictors of mortality and adverse events in this patient cohort.

    Main Methods:

    • Retrospective analysis of 158 patients with unstable angina over a 4-year period.
    • In-hospital outcomes included myocardial infarction and mortality.
    • Long-term follow-up (3-7 years) assessed mortality, recurrent myocardial infarction, and angina severity.

    Main Results:

    • Acute mortality rate was 4%, with 13% experiencing in-hospital myocardial infarction.
    • Persisting angina and no prior history of ischemia predicted in-hospital events.
    • Long-term mortality was associated with age >60, cardiomegaly, pulmonary venous congestion, and higher coronary prognostic index.
    • Annual long-term mortality was approximately 5% for survivors.

    Conclusions:

    • Unstable angina carries significant short-term and long-term risks.
    • Identifying high-risk patients early can guide management and improve outcomes.
    • Age, cardiac status, and prognostic scores are key factors in long-term risk stratification.
