Risk factors for coronary heart disease are categorized into which groups?

• A. Primary & Secondary
• B. Genetic
• C. Environmental
• D. Acute & Chronic

Answer: (A)

Risk factors for coronary heart disease are categorized as primary factors that directly contribute to the disease, and secondary factors that can increase risk when present with the primary ones. This distinction helps emphasize what drives the disease most strongly versus what can amplify risk in combination with those main factors. The other groupings—genetic, environmental, or acute versus chronic—describe different dimensions (such as heredity, setting, or timing) rather than how directly a factor influences disease risk, so they don’t fit this common way of organizing CHD risk factors.
