Insights
This study found that while acute myocardial infarction (AMI) mortality rates were similar to national averages, secondary medication adherence on discharge was suboptimal, especially for women and older patients. Evidence-based guideline implementation for AMI management requires enhancement.
Area of Science:
- Cardiology
- Internal Medicine
- Public Health
Background:
- Cardiovascular disease, particularly acute myocardial infarction (AMI), is a leading cause of mortality in Europe.
- Under-representation of women, elderly, and comorbid patients in clinical trials impacts AMI treatment guidelines.
- These patient groups often experience worse long-term outcomes following AMI.
Purpose of the Study:
- To evaluate the management of acute myocardial infarction (AMI) in a non-academic general hospital setting.
- To assess adherence to evidence-based guidelines for AMI treatment and secondary prevention.
- To identify disparities in care for specific patient demographics.
Main Methods:
- Retrospective review of 92 acute myocardial infarction (AMI) cases admitted in 2000.
- Analysis of patient demographics, in-hospital and 30-day mortality, and treatment interventions.
- Examination of discharge medication prescriptions (aspirin, beta-blockers, statins, ACE inhibitors) and their correlation with patient characteristics.
Main Results:
- In-hospital mortality was 12% and 30-day mortality was 14%, with no significant differences based on gender or age.
- Thrombolysis was administered to 93% of eligible patients.
- Discharge prescription rates for aspirin (81%) and beta-blockers (41%) were below established European and American benchmarks. Females, elderly patients (≥70 years), and those with comorbidities were less likely to receive guideline-recommended secondary preventive medications.
Conclusions:
- While AMI mortality in this general hospital aligns with national figures, there is a clear need to improve the implementation of evidence-based guidelines.
- Particular focus is required on enhancing secondary pharmacological measures prescribed at discharge to optimize long-term outcomes.
- Addressing disparities in medication prescription for vulnerable patient groups is crucial for equitable AMI care.
Abstract:
Cardiovascular disease is the leading cause of death in Europe. Acute myocardial infarction (AMI) is among the most common of its manifestations. Women and older patients are under-represented in most trials of treatment for AMI, as are those with significant co-morbidities. These patients also have a worse long term outcome after AMI. We sought to evaluate the management of AMI in a small non-academic general hospital. A review was performed of cases of AMI during 2000. Ninety-two cases were analysed, 69% were male. The mean age was 70 years. In-hospital mortality was 12%; 30-day mortality was 14%. There was no gender or age difference in mortality. Of thirty eligible patients, twenty-eight were thrombolysed (93%). Aspirin (81%) and beta-blocker (41%) prescription on discharge were below published European and American rates. Females were significantly less likely to receive aspirin or beta-blockers on discharge. Those aged 70 years or more were less likely to receive beta-blockers, statins or ACE inhibitors on discharge. Those with co-morbidities were less likely to receive beta-blockers or statins on discharge. This study highlights the difficulty in realising evidence based guidelines optimal management of AMI in clinical practice. While the outcome with regard to mortality is similar to national figures, there is a need to enhance care, with particular emphasis on secondary pharmacological measures prescribed on discharge.
