Which type of intervention has been shown to have a dose-response relationship in CAD intervention outcomes?

• A. Pharmaceutical intervention
• B. Physical therapy sessions
• C. Adherence to lifestyle changes
• D. Standard medical care

Answer: (C)

C. Adherence to lifestyle changes is correct because it has been demonstrated that the degree to which individuals adhere to lifestyle modifications—such as diet, exercise, smoking cessation, and stress management—directly correlates with improvements in cardiovascular health outcomes, particularly in patients with coronary artery disease (CAD). Studies show that patients who make significant lifestyle changes tend to experience more substantial reductions in cardiovascular risk factors, such as blood pressure, cholesterol levels, and weight, leading to a better overall prognosis. This dose-response relationship indicates that greater adherence to these interventions results in better health outcomes. For example, more rigorous adherence to a heart-healthy diet and regular physical activity can lead to more significant decreases in the progression of CAD and improve markers like heart function and overall mortality rates. Other interventions listed may have their benefits, but they do not exhibit the same clear dose-response relationship when it comes to their impact on CAD outcomes. Pharmaceutical interventions can help manage symptoms and control risk factors, but their effectiveness does not directly depend on a dose-response similar to lifestyle changes. Standard medical care could involve a combination of treatments, but it may not yield results based purely on adherence, and physical therapy sessions, while helpful, do not typically have such a straightforward correlation with CAD outcomes as seen
