Why Cardiovascular Biomarkers And Prevention Matters For Heart Patients

Preventive cardiology is the part of heart medicine that works before anything goes wrong. It assesses risk from blood pressure, cholesterol, blood sugar, smoking, weight, activity, sleep and family history, then matches the strength of treatment to the size of the risk. For most people the biggest gains come from a small number of unglamorous measures sustained over decades rather than from anything new. The field exists because the first symptom of coronary disease is, for a significant minority of people, also the last one.
