For decades, doctors had nothing more sophisticated than a stress test to identify potential heart problems. Not anymore. Cardiologists now use advanced imaging and blood tests that give a much more accurate assessment of heart attack risk.
These tests are the best ways to tell who is in danger, because they can catch cardiovascular disease 20 to 30 years before it gets severe enough to cause a heart attack or stroke. They are available at most major medical centers and hospitals. If your doctor doesn’t request them for you, demand the ones that are recommended for your age group and risk category.
1) Carotid Intimal Medial Thickness Test
How It Works: This “ultrasound of the neck” takes a picture of the left and right carotid arteries, which supply blood to your head and brain. After putting a gel on your neck, a technician glides an ultrasound transducer over your carotids to measure the thickness of the arteries’ lining.
Duration: 15 minutes
Why It’s Heart Smart: Studies show a link between the abnormal thickness of the carotid lining and coronary artery disease. This test can detect even the earliest stages before blood flow is blocked. Because it’s not an x-ray, it’s also helpful for women who are or may be pregnant.
What the Results Mean: You’ll get two numbers: the thickness of your carotid lining (normal is less than 1.06 mm) and your “arterial age,” an estimate of how that thickness compares to others in your age group. If your arteries are more than 8 years “older” than you are, your doctor can tailor a treatment to reduce your risk.
2) High-Sensitivity C-Reactive Protein Test
How It Works: A blood test measures CRP, a protein in your blood that’s a strong indicator of inflammation throughout your body.
Duration: 5 minutes
Why It’s Heart Smart: Cholesterol plaque injures blood vessels, triggering inflammation and raising CRP levels in your blood. That’s dangerous because people with high levels of CRP may be up to 4 times more likely to suffer a heart attack or stroke. A high CRP is most dangerous if you also have another risk factor: a waist circumference of more than 35 inches, indicating the presence of belly fat.
What the Results Mean: If your score is under 1.0 mg per liter, your risk of developing heart disease is
