Insights
Previous angina improved short-term outcomes for patients. However, multi-vessel coronary disease indicated a worse long-term prognosis after hospital discharge.
Area of Science:
- Cardiology
- Clinical Medicine
- Health Outcomes Research
Background:
- Previous angina is a common symptom in patients with coronary artery disease.
- Understanding the impact of previous angina on patient outcomes is crucial for effective treatment strategies.
Purpose of the Study:
- To evaluate the in-hospital and long-term outcomes of patients with previous angina.
- To identify factors associated with long-term prognosis in this patient group.
Main Methods:
- Retrospective analysis of patient data.
- Comparison of outcomes between patients with and without previous angina.
- Identification of predictors for long-term prognosis.
Main Results:
- Patients with previous angina showed improved in-hospital outcomes.
- No significant benefit in long-term prognosis was observed after hospital discharge.
- Multi-vessel coronary disease was associated with a worse long-term prognosis in patients with previous angina.
Conclusions:
- Previous angina may offer short-term benefits but does not improve long-term outcomes.
- Multi-vessel coronary disease is a critical factor influencing long-term prognosis in patients with prior angina.
- Further research is needed to optimize long-term management for these patients.
Abstract:
Although the present study revealed that previous angina improved in-hospital outcome, no further benefit was observed once the patients left the hospital. The worse long-term prognosis was associated with multi-vessel coronary disease in patients with previous angina.
