Insights
Management of acute myocardial infarction (MI) in Riyadh largely followed evidence-based guidelines. However, increased use of ACE inhibitors and hypolipidemic agents is recommended for better patient outcomes in acute MI care.
Area of Science:
- Cardiology
- Internal Medicine
- Public Health
Background:
- Acute myocardial infarction (MI) presents a significant global health challenge, marked by high mortality and morbidity rates.
- Established clinical trials and guidelines aim to optimize patient survival and quality of life following acute MI.
- Assessing adherence to evidence-based practices in acute MI management is crucial for healthcare quality improvement.
Purpose of the Study:
- To evaluate the compliance of current acute myocardial infarction (MI) management practices with evidence-based guidelines.
- To assess therapeutic interventions and discharge medications administered to acute MI patients in a major community hospital.
- To compare patient outcomes, including mortality, with established clinical recommendations.
Main Methods:
- Retrospective data collection from 335 patients diagnosed with acute MI admitted to the Coronary Care Unit (CCU) at Riyadh Medical Complex (RMC) over a one-year period (April 1999-April 2000).
- Documentation of therapeutic modalities upon admission and discharge medications, including beta-blockers, ACE inhibitors, nitrates, hypolipidemic agents, and aspirin.
- Analysis of patient outcomes, specifically all-cause mortality, and comparison with current management guidelines.
Main Results:
- A total of 335 patients (94% male) were included, with 80.9% receiving thrombolytic therapy.
- Discharge medications included aspirin (100%), nitrates (83.9%), beta-blockers (76.1%), and angiotensin-converting enzyme (ACE) inhibitors (61.5%).
- A low incidence of hypolipidemic agent use (4.5%) was observed. Overall mortality was 6.6% (22/335).
Conclusions:
- Acute MI management at RMC demonstrated substantial compliance with evidence-based practices.
- There is a need for increased awareness and utilization of ACE inhibitors and hypolipidemic agents to maximize patient benefits.
- Development of national guidelines for acute MI management is recommended to further enhance the quality of care.
Objective:
Acute myocardial infarction (MI) is a major health problem with a substantial fatality and morbidity. The management of patients with acute MI has been addressed in major trials to improve the survival and enhance the quality of life of the patients. Numerous guidelines have been established for the management of such patients. The objective of this study is to determine whether the current practice in managing patients admitted with acute MI in a major community hospital in Riyadh is evidence based compliant.
Methods:
The data were collected from patients admitted to the Coronary Care Unit (CCU), Riyadh Medical Complex (RMC), Riyadh, Kingdom of Saudi Arabia, a 1500 bed community hospital, with a diagnosis of acute MI over one-year period (April 1999 to April 2000). The administration of different therapeutic modalities upon admission as well as discharge medications was obtained. Patients outcome (all cause mortality) post treatment were collected. The data was analyzed and compared with the current guidelines.
Results:
A total of 335 patients, 315 males (94%), were admitted to the CCU of RMC with a diagnosis of acute MI. Two hundred and seventy-one patients (80.9%) received thrombolytic therapy. Discharge medications were beta-blocker in 255 (76.1%), angiotensin converting enzyme inhibitors in 206 (61.5%), nitrates in 281 (83.9%), hypolipidemic agents in 15 patients (4.5%), and aspirin in all patients. The outcome of these patients obtained either alive or dead was 313 (93.4%) and 22 (6.6%) (p<0.00001).
Conclusion:
The patients with acute MI received management compliant with evidence-based practice. However, more awareness to the use of angiotensin converting enzyme inhibitors as well as hypolipidemic agents is needed to provide maximum benefit to these patients. Moreover, national guidelines for the management of acute MI are needed for improvement of quality of care.
