**INTRODUCTION** (5-10 minutes)
Preventive medicine is a vital component of healthcare that focuses on preventing or delaying the onset of disease through education, lifestyle modification, and evidence-based interventions.¹² Cardiovascular disease remains the leading cause of mortality worldwide, accounting for 17.9 million deaths annually.¹ Recent guidelines emphasize early intervention and risk stratification to reduce cardiovascular events and improve outcomes.²

**MAIN CONTENT** (45-60 minutes)
### **Section 1: Definitions and Epidemiology**
Preventive medicine encompasses a broad range of interventions aimed at preventing or delaying the onset of disease, including vaccination, screening, and lifestyle modification.³ The World Health Organization (WHO) estimates that approximately 70% of all deaths worldwide are due to preventable causes.⁴
* **Definition:** Preventive medicine is a branch of medicine that focuses on preventing or delaying the onset of disease through education, lifestyle modification, and evidence-based interventions.
* **Epidemiology:** The prevalence of cardiovascular disease varies globally, with an estimated 17.9 million deaths annually worldwide.⁵
### **Section 2: Pathophysiology and Mechanisms**
Cardiovascular disease is a complex condition influenced by multiple factors, including genetics, lifestyle, and environmental factors.⁶ Key pathophysiological mechanisms include:
* Vascular inflammation
* Endothelial dysfunction
* Atherosclerosis
* Hypertension
### **Section 3: Clinical Presentation**
Common clinical presentations of cardiovascular disease include:
* Angina pectoris
* Myocardial infarction (MI)
* Stroke
* Heart failure
### **Section 4: Diagnostic Approach**
Evidence-based diagnostic algorithms for cardiovascular disease include:
* Resting electrocardiogram (ECG) and echocardiography for cardiac structure and function evaluation.
* Blood pressure monitoring for hypertension assessment.
* Lipid profile analysis for risk stratification.
### **Section 5: Treatment and Management**
Guidelines-based treatment protocols for cardiovascular disease emphasize lifestyle modification, medication therapy, and invasive interventions as needed.⁷
* **Lifestyle modification:** Patients with high-risk profiles should be encouraged to adopt a healthy diet, engage in regular physical activity, and maintain optimal weight.
* **Medication therapy:** Statins, beta-blockers, and ACE inhibitors are recommended for primary and secondary prevention of cardiovascular events.
### **Section 6: Complications and Prognosis**
Complication rates for cardiovascular disease vary depending on the specific condition.⁸ Longitudinal study data highlights:
* **Prognostic factors:** Age, hypertension, diabetes mellitus, and smoking are significant predictors of adverse outcomes in patients with cardiovascular disease.
### **CLINICAL PEARLS**
1. Regular screening and risk stratification are crucial for early detection and intervention.
2. Lifestyle modification is a key component of preventive medicine.
3. Early invasive interventions can significantly improve outcomes for high-risk patients.
### **KEY POINTS SUMMARY**
* Preventive medicine aims to prevent or delay the onset of disease through education, lifestyle modification, and evidence-based interventions.
* Cardiovascular disease is a leading cause of mortality worldwide, emphasizing the need for early intervention and risk stratification.
* Lifestyle modification, medication therapy, and invasive interventions are key components of treatment protocols.
