Patient Education: Educating patients about the importance of a healthy diet, regular exercise, and avoiding smoking can significantly reduce the risk of heart disease. 2. Monitoring Vital Signs: Regularly checking blood pressure, heart rate, and cholesterol levels helps in early detection of cardiac issues. 3. Administering Medication: Ensuring patients adhere to prescribed medications for conditions like hypertension and high cholesterol. 4. Lifestyle Counseling: Providing guidance on stress management techniques and encouraging healthy lifestyle changes.
