Problem-Based Learning
Topic: Acute Coronary Syndrome (ACS)
Learning Objective:
Students will understand the pathophysiology, clinical presentation, diagnosis, and management of acute coronary syndrome through problem-based learning scenarios.
Duration: 90 minutes
Materials:
- Case studies on ACS
- Whiteboard or flip chart
- Markers
- Handouts on ACS guidelines
Lesson Structure:
1. Introduction to ACS (10 minutes)
- Brief overview of ACS: Definition, Types (STEMI, NSTEMI, unstable angina), and importance
- Discuss common risk factors: hypertension, hyperlipidemia, smoking, diabetes, family history
2. Problem-Based Learning Introduction (10 minutes)
- Explain the problem-based learning (PBL) approach: learning through solving real-world problems
- Emphasize active participation, collaboration, and critical thinking
- Divide students into small groups
3. Case Study Presentation (30 minutes)
- Distribute case studies on ACS to each group
- Each group analyzes the case, identifying key symptoms, risk factors, and potential diagnoses
- Encourage discussion and debate within groups
4. Group Discussion (20 minutes)
- Each group presents their findings to the class
- Facilitate discussion on differential diagnoses, diagnostic tests, and treatment options based on the presented cases
- Encourage students to justify their decisions with evidence from guidelines and literature
5. Guided Review of Management Guidelines (10 minutes)
- Summarize the management principles for ACS: MONA-BASH (morphine, oxygen, nitroglycerin, aspirin, beta-blockers, antiplatelet therapy, statins, heparin)
- Discuss the role of reperfusion therapy (PCI vs. fibrinolysis) in STEMI
- Review risk stratification tools (TIMI and GRACE scores) and their implications for management
6. Application and Reflection (10 minutes)
- Ask students to reflect on the learning process and how PBL helped them understand ACS better
- Encourage students to think about how they would approach similar cases in clinical practice
7. Conclusion (5 minutes)
- Summarize key points learned during the session
- Provide resources for further reading on ACS
Assessment:
- Informal assessment through observation of group discussions and presentations
- Formal assessment through a follow-up quiz or written reflection on the session
