Insights
Successful thrombolytic therapy for acute myocardial infarction (AMI) significantly improves 4-year survival. Early coronary artery bypass grafting (CABG) in patients with a patent infarct artery further enhances survival and cardiac function.
Area of Science:
- Cardiology
- Internal Medicine
Background:
- Long-term prognosis after thrombolytic therapy for acute myocardial infarction (AMI) remains unclear.
- Assessing outcomes is crucial for guiding treatment strategies in AMI patients.
Purpose of the Study:
- To investigate the 4-year prognosis of patients with AMI treated with thrombolysis.
- To evaluate the impact of infarct artery patency and early coronary artery bypass grafting (CABG) on long-term outcomes.
Main Methods:
- A 4-year follow-up study involving 227 patients with AMI.
- Patients were categorized into patent (n=171) and occluded (n=56) groups based on reperfusion status post-catheterization.
- Comparison of mortality rates and left ventricular function between groups, including those who underwent early CABG.
Main Results:
- The patent group showed significantly reduced hospital (13%) and 4-year (14%) mortality rates (p ≤ 0.005).
- Patients with a patent infarct artery who received early CABG exhibited improved survival (p < 0.10) and better left ventricular function (p < 0.01) compared to those without CABG.
- Early CABG was associated with lower rates of fatal reinfarction and cardiogenic shock.
Conclusions:
- Successful thrombolysis for AMI leads to improved 4-year survival.
- Early CABG in patients with a patent infarct artery further enhances survival and cardiac function, reducing adverse events.
Abstract:
The long-term prognosis after thrombolytic therapy in patients with acute myocardial infarction (AMI) is unknown. This question was investigated in a 4-year follow-up study of 227 patients. According to the status of reperfusion at the end of the acute catheterization, the patients were divided into a patent (n = 171) and an occluded (n = 56) group. Both hospital and 4-year mortality rates were significantly reduced in the patent group by 13 and 14%, respectively (p less than or equal to 0.005 for both). Baseline variables known to be important for prognosis did not differ between the 2 groups. Patients with a patent infarct artery who underwent early acute coronary artery bypass grafting (CABG) had a greater survival (p less than 0.10) and better left ventricular function (p less than 0.01) than did patients with a patent infarct artery who did not undergo CABG. This difference was associated with a lower frequency of fatal reinfarction and cardiogenic shock in the CABG group. Thus, survival is improved up to 4 years after successful thrombolysis and appears to be further enhanced by early CABG.
