Patients with unstable angina (UA) pectoris who did not receive interventional management were more likely to be readmitted. Non-interventional treatment, diffuse coronary artery disease, and non-diagnostic stress tests predict readmission.

Area of Science:

  • Cardiology
  • Internal Medicine

Background:

  • Unstable angina (UA) pectoris is a critical condition requiring careful management to prevent readmissions.
  • Understanding readmission predictors is vital for optimizing patient care and resource allocation.

Purpose of the Study:

  • To identify patient characteristics associated with readmission after hospitalization for primary unstable angina pectoris.
  • To evaluate the impact of management strategies on readmission rates in UA pectoris patients.

Main Methods:

  • A prospective study of 120 patients hospitalized for UA pectoris, followed for 22 months post-discharge.
  • Patients were categorized into readmitted (Group A, n=50) and non-readmitted (Group B, n=70) groups.
  • Coronary angiography and exercise stress tests were performed before discharge; univariate and regression analyses were used to identify predictors.

Main Results:

  • Univariate analysis identified age >70, non-diagnostic stress tests, diffuse coronary artery disease, and non-interventional management as predictors of readmission.
  • Regression analysis highlighted non-interventional management, non-diagnostic treadmill tests, and diffuse coronary artery disease as significant factors for readmission.
  • Readmitted patients had a higher incidence of myocardial infarction but similar 2-year survival rates compared to non-readmitted patients.

Conclusions:

  • Non-interventional management is the most significant factor for readmission in the interventional era for unstable angina pectoris.
  • Coronary revascularization decisions should not be based solely on patient age.
  • Optimizing management strategies, particularly considering revascularization, is crucial for reducing readmissions in UA pectoris.
