Ultrasound evaluation of carotid arteries to assess blood flow and ischemic stroke risk. Screens for narrowing or blockage of blood vessels. Quick non-invasive test for stroke prevention.
Cardiovascular health screening combines blood markers (lipid panel, CRP, homocysteine, Lp(a)) with imaging when appropriate to assess your heart disease risk. Blood tests reveal cholesterol levels, inflammation, and metabolic markers that predict cardiovascular events. Heart disease remains the leading cause of death worldwide, but early detection of risk factors allows for effective intervention through lifestyle changes and, when necessary, medication.

Biomarkers Tested
4The combined measure of all cholesterol in your blood, including HDL, LDL, and VLDL. While useful as an overview, the breakdown between HDL and LDL is more clinically meaningful for assessing cardiovascular risk.
Often called 'bad' cholesterol, LDL deposits cholesterol in artery walls, contributing to plaque buildup and atherosclerosis. LDL is the primary target for cardiovascular risk reduction through diet, exercise, and medication.
Often called 'good' cholesterol, HDL carries cholesterol away from arteries back to the liver for removal. Higher HDL levels are protective against heart disease. Exercise, healthy fats, and moderate alcohol intake can raise HDL.
The most common type of fat in the body, stored for energy. Elevated triglycerides — often from excess sugar, alcohol, or calories — increase cardiovascular risk and can cause pancreatitis at very high levels.
