What is a key protective factor against cardiovascular disease (CVD)?

Avoiding smoking is identified as a key protective factor against cardiovascular disease (CVD) because smoking is well-established as a major risk factor that significantly contributes to the onset and progression of heart-related conditions. When individuals refrain from smoking, they greatly reduce their risk of developing CVD since tobacco use damages blood vessels, leads to plaque formation, and promotes blood clots, all of which increase the likelihood of heart attacks and strokes.

In contrast, increasing salt intake, engaging in sedentary behavior, and experiencing high blood pressure are all factors that can elevate the risk of cardiovascular diseases. High salt consumption is linked to elevated blood pressure, which is a significant risk factor for CVD, and a sedentary lifestyle further exacerbates health issues by contributing to weight gain and reducing cardiovascular fitness. Thus, the avoidance of smoking clearly stands out as a primary protective measure in promoting heart health.
