[Features of acute myocardial infarction among aged patients]
Insights
Elderly patients experiencing acute myocardial infarction face higher risks and undertreatment, leading to significantly increased mortality compared to younger individuals. This highlights a critical need for improved care strategies in this demographic.
Area of Science:
- Cardiology
- Geriatric Medicine
- Clinical Research
Context:
- Acute myocardial infarction (AMI) presents unique challenges in elderly populations.
- Aged patients often exhibit a higher risk profile upon admission for AMI.
- There's a documented tendency for underutilization of evidence-based treatments in this demographic.
Purpose:
- To characterize the clinical presentation and outcomes of acute myocardial infarction in patients aged 65 years and older.
- To compare treatment patterns and mortality rates between elderly and younger AMI patients.
- To identify disparities in care and outcomes for older adults with AMI.
Summary:
- Analysis of 1,358 AMI admissions identified 580 patients (43%) aged 65+.
- Elderly patients showed increased hemodynamic instability and anterior wall infarctions.
- Reperfusion therapy and beta-blocker use were lower in the aged group, with hospital mortality at 25% vs. 8% (p < 0.01).
- Five-year mortality for aged patients was 33%.
Impact:
- Elderly patients with AMI have a worse prognosis and are often undertreated.
- Findings underscore the need for tailored treatment protocols for older adults with myocardial infarction.
- Improved management strategies are crucial to reduce mortality and complications in geriatric AMI patients.
Background:
Among aged patients, acute myocardial infarction has more complications and there is a tendency to underuse proven treatments.
Aim:
To report the features of acute myocardial infarction among aged patients.
Material And Methods:
Analysis of a registry of patients with acute myocardial infarction admitted to a coronary unit. For the purposes of analysis, patients aged 65 years or more were selected. Follow up was made consulting medical records, calling patients by telephone or consulting death records at the National Identification Service.
Results:
A total of 1.358 patients were admitted in the study period with a diagnosis of acute myocardial infarction and 580 (43%) were aged 65 years or more. On admission, this age group had a higher frequency of hemodynamic instability and anterior wall infarctions. Reperfusion therapy and beta blockers were used less commonly in this group. Hospital mortality among patients younger or older than 65 year was 8 and 25%, respectively (p < 0.01). Among aged patients, five years mortality was 33%.
Conclusions:
Among aged patients, acute myocardial infarction has a higher risk profile on admission, is usually undertreated and has higher mortality than younger subjects.
