Cardiovascular markers are biological indicators that help assess the health of the heart and blood vessels. Common markers include cholesterol levels, blood pressure, and C-reactive protein (CRP). These markers can provide insights into the risk of developing cardiovascular diseases, such as heart attacks and strokes. Healthcare professionals often measure these markers through blood tests and physical examinations. Monitoring cardiovascular markers is essential for early detection and management of heart-related conditions, allowing for timely interventions and lifestyle changes to improve overall heart health.
