[Balloon coronary angioplasty in macrofocal myocardial infarction survivors]
Insights
Delayed balloon coronary angioplasty (DBCA) in myocardial infarction (MI) survivors significantly improves long-term prognosis. This study shows DBCA reduces 5-year lethality and cardiac events in MI survivors.
Area of Science:
- Cardiology
- Interventional Cardiology
Context:
- Myocardial infarction (MI) survivors face significant long-term risks.
- Assessing the long-term efficacy of delayed balloon coronary angioplasty (DBCA) is crucial for patient outcomes.
Purpose:
- To evaluate the 5-year outcomes of delayed balloon coronary angioplasty (DBCA) in survivors of myocardial infarction (MI).
- To analyze endpoints including mortality, recurrent MI, angina, arrhythmia, heart failure, and hospitalization rates.
Summary:
- A retrospective analysis of 57 patients undergoing DBCA 3 weeks to 6 months post-MI was conducted.
- Overall and cardiac mortality was 8.8%. Over 5 years, 70.1% experienced angina recurrence, 10.5% had repeat MI, 5.3% developed arrhythmias, and 22.8% showed heart failure.
- DBCA combined with drug therapy significantly improved long-term prognosis and halved 5-year lethality after Q-wave MI.
Impact:
- Delayed balloon coronary angioplasty (DBCA) offers a significant survival benefit for myocardial infarction (MI) survivors.
- This intervention, alongside drug therapy, can reduce major adverse cardiac events and improve the long-term outlook for patients post-MI.
Abstract:
Long-term results of delayed balloon coronary angioplasty (DBCA) in myocardial infarction (MI) survivors were studied by the following end points: general and cardiac lethality, repeated MI, renewal of anginal attacks, life-threatening arrhythmia, symptoms of circulatory deficiency, rate of hospitalization during 5 years of follow-up. 57 patients who had undergone DBCA 3 weeks--6 months after MI were analyzed retrospectively. Overall and cardiac lethality was 8.8%. For 5 years of follow-up renewal of angina was seen in 70.1% patients, repeated MI developed in 10.5%, life-threatening arrhythmia and conductivity disorders were revealed in 5.3%, chronic cardiac failure--in 22.8% patients. DBCA in survivors of macrofocal MI in combination with current drug therapy to improves significantly long-term prognosis and reduces twice 5-year lethality after Q-wave MI.
