What is Coronary Heart Disease (CHD) Risk?

Coronary Heart Disease (CHD) risk measures the likelihood of developing heart-related conditions due to risk factors such as cholesterol levels, blood pressure, age, gender, and habits like smoking. Understanding your CHD risk allows you to take preventive actions.

How is CHD Risk Calculated?

CHD risk is calculated using frameworks like the **Framingham Risk Score**, which evaluates several factors:

• Age: CHD risk increases with age, especially after 45 in men and 55 in women.
• Total Cholesterol: Higher cholesterol levels raise the risk.
• HDL Cholesterol: High HDL (good cholesterol) reduces the risk.
• Systolic Blood Pressure: Elevated blood pressure contributes to higher risk.
• Smoking: A significant risk factor for CHD.
• Blood Pressure Medication: Indicates elevated blood pressure management, impacting risk scores.

Risk Levels

Using the Framingham Risk Score, CHD risk levels are categorized as:

• Low Risk: Less than 10% likelihood of CHD within 10 years.
• Moderate Risk: 10–20% likelihood.
• High Risk: Greater than 20% likelihood.

Example Calculation

Inputs:
Age: 45
Total Cholesterol: 240 mg/dL
HDL Cholesterol: 50 mg/dL
Systolic BP: 135 mmHg
Smoker: Yes
On BP Medication: Yes

Risk Points:
Age: +2
Total Cholesterol: +2
HDL: 0
Systolic BP: +2
Smoker: +2

Total: 8 points
CHD Risk Level: High

Why Assess CHD Risk?

• Preventive Action: Identifies risk factors early to guide lifestyle or medical interventions.
• Health Monitoring: Tracks risk factors over time to assess progress and adjust treatments.
• Guided Treatment: Helps doctors make informed decisions about care plans.
