Why would you be sent to a cardiologist because of a blood test?

You might be referred to a cardiologist because a blood test revealed abnormal levels of cardiac biomarkers, such as troponin or natriuretic peptides, which can indicate heart damage or strain. Additionally, elevated cholesterol or triglyceride levels may suggest an increased risk of cardiovascular disease, prompting further evaluation. The cardiologist can then assess your heart health and recommend appropriate treatment or lifestyle changes.
