In the context of cardiovascular disease prevention and risk stratification in India, all of the following are recognized modifiable risk factors EXCEPT:

Explanation

## Modifiable vs Non-Modifiable CVD Risk Factors ### Classification of Risk Factors **Key Point:** Risk factors for CVD are classified as either modifiable (can be changed through intervention) or non-modifiable (fixed, cannot be altered). This distinction is critical for prevention strategies. ### Risk Factor Comparison Table | Risk Factor | Category | Modifiability | Intervention | |-------------|----------|----------------|---------------| | Hypertension | Modifiable | Yes | Lifestyle, antihypertensives | | Family history of premature CVD | Non-modifiable | NO | Cannot be changed | | Physical inactivity | Modifiable | Yes | Exercise, activity counseling | | Dyslipidemia | Modifiable | Yes | Diet, statins, lifestyle | | Smoking | Modifiable | Yes | Cessation programs | | Diabetes mellitus | Modifiable | Yes | Glycemic control | | Obesity | Modifiable | Yes | Weight reduction | | Age | Non-modifiable | NO | Cannot be changed | | Male sex | Non-modifiable | NO | Cannot be changed | ### Family History: Non-Modifiable **High-Yield:** Family history of premature CVD (defined as CVD in male first-degree relatives <55 years or female first-degree relatives <65 years) is a NON-MODIFIABLE risk factor. It indicates genetic predisposition and cannot be altered through lifestyle or medical intervention. **Clinical Pearl:** Individuals with positive family history require: - Earlier risk assessment - More aggressive management of modifiable risk factors - Consideration of pharmacological prevention (e.g., statins) even at lower absolute risk levels - Regular cardiovascular screening ### Why Distinguish Modifiable from Non-Modifiable? **Mnemonic:** MODIFY — Modifiable factors guide intervention strategy; Non-modifiable factors guide risk stratification and screening intensity. 1. **Modifiable factors** → Target for primary prevention and lifestyle modification 2. **Non-modifiable factors** → Determine baseline risk and screening frequency [cite:Park 26e Ch 9; WHO CVD Risk Assessment Guidelines]
