Insights
Coronary revascularization significantly improves 3-year survival for elderly patients with acute myocardial infarction compared to conservative care. Invasive treatment also reduced cardiovascular events, though rehospitalization rates were similar.
Area of Science:
- Cardiology
- Geriatric Medicine
- Interventional Cardiology
Background:
- Elderly patients with acute myocardial infarction (AMI) face higher risks due to comorbidities and complex coronary anatomy.
- Optimal management strategies for AMI in this demographic remain a critical clinical question.
Purpose of the Study:
- To compare three-year outcomes of coronary revascularization versus conservative management in elderly patients with AMI.
- To evaluate the impact of invasive treatment on survival, rehospitalization, and cardiovascular events.
Main Methods:
- A cohort of 155 patients over 75 years old with AMI was analyzed.
- Patients received either invasive treatment (coronary angioplasty, n=58) or conservative medical treatment (n=97).
- Kaplan-Meier and Mantel-Cox log rank tests assessed 3-year survival, rehospitalization, and mean survival time.
Main Results:
- Three-year survival was significantly higher in the invasive treatment group (74.1%) versus the conservative group (29.9%) (P<0.001).
- Mean survival time was longer for invasive treatment (31.50 months) compared to conservative (24.65 months) (P<0.001).
- Rehospitalization rates at 3 years showed a trend towards improvement with invasive treatment (34.05 months vs. 30.03 months, P=0.004).
Conclusions:
- Coronary revascularization in elderly AMI patients reduces all-cause mortality and cardiovascular events at 3 years.
- While rehospitalization rates were statistically similar, invasive treatment showed improved probability.
- Coronary revascularization should be strongly considered for elderly AMI patients to improve overall survival.
Objectives:
Elderly patients who present with acute myocardial infarction are at increased risk for adverse outcomes owing to higher comorbidity burden and complicated coronary anatomy. We evaluated the three-year outcomes following coronary revascularization compared to conservative management among elderly patients presenting with acute myocardial infarction.
Methods:
155 patients over 75 years of age who were admitted for acute myocardial infarction underwent invasive treatment with coronary angioplasty (n=58) or only medical treatment (n=97). The Kaplan-Meier log rank test was used to compare 3-year survival and rehospitalization probability and the Mantel-Cox log rank test was used to compare mean survival time between groups.
Results:
In the Invasive treatment group (ITG) cohort, 3-year survival probability was 74.1% as compared to 29.9% in the Conservative treatment group (CTG) cohort (P<0.001). Mean survival time at 3 years of follow-up was 31.50 (95% CI 29.35-33.65) months among ITG patients versus 24.65 (95% CI 22.71-26.59) months among CTG patients (P<0.001). Mean time to rehospitalization at 3 years was 34.05 (95% CI 32.37-35.72) in the ITG cohort compared to 30.03 (95% CI 28.13-31.93) in the CTG cohort (P=0.004).
Conclusion:
Coronary revascularization among elderly patients with acute myocardial infarction reduces both all-cause mortality and cardiovascular events at 3-year follow-up. However, rates of rehospitalizations remain statistically similar between groups. Moreover, invasive treatment imparted improved rehospitalization probability compared to conservative treatment. This observation can be partially explained by a reduction in the frequency of myocardial infarction among those who underwent invasive treatment. While a thorough clinical assessment is required prior to treatment determination among elderly patients with acute myocardial infarction, coronary revascularization should be strongly considered as an intervention that likely improves overall survival probability.
