When looking for clues about your heart health, your healthcare provider will probably start with blood tests. These tests often reveal risks for coronary artery and other heart disease and sometimes provide warnings for heart failure. Blood testing often requires fasting beforehand so be sure to check with your healthcare provider.
Blood profiles test for abnormal levels of:
• Fats (lipids) in your blood.
• Low-density lipoprotein (LDL) - the "bad” cholesterol - that causes the accumulation of plaque in your arteries.
• High-density lipoprotein (HDL) - the "good” cholesterol - helps clear your arteries of LDL.
• Triglycerides, another type of fat, that raise your risk of heart disease.
• Blood sugar (glucose) to detect the presence of diabetes and glucose intolerance (pre-diabetes).
• C-reactive protein to determine inflammation in your body. This test is given only to individuals who are at risk for heart disease and may be used with other blood tests to assess risk factors for heart disease.
• Complete blood count, thyroid studies, arterial blood gases.
