Why It Matters

Blood Pressure

Your doctor will take your blood pressure during your annual visit, but once a month check it yourself at a blood pressure station at the mall, supermarket, or drugstore.

Below 120/80 mmHg (below 115/75 mmHg if you're over 40). Above 120/80 mmHg is considered pre-hypertension; above 140/90 mmHg is full-blown hypertension.

Hypertension more than triples your risk for heart disease and stroke. High blood pressure not only makes your heart work harder to pump blood throughout your body, it also hardens arteries prematurely and causes micro-tears in artery walls that can trap plaque and cause blockages.

Cholesterol/Triglycerides

Every five years your doctor should check the cholesterol/triglyceride levels in your blood, more often if you already have high cholesterol or are using medication to lower it. Ask your doctor about a home test kit like CardioChek ($105 plus test strips, available at drugstores and online). 

Aim for LDL cholesterol below 100 mg/dl; HDL cholesterol above 50 mg/dl; triglycerides below 150 mg/dl.

Having high LDL cholesterol and triglycerides, along with low HDL cholesterol, leads to artery plaque. About 50% of heart attacks and 20% of strokes are linked to elevated cholesterol levels.

Fasting Blood Glucose

If you have no risk factors, get this test every three years, starting at 45. But if you're overweight and have at least one other risk factor for diabetes (family history; hypertension; elevated triglycerides, and low HDL levels; or you developed gestational diabetes or had a baby weighing more than nine pounds) ask your doctor about doing this test now.

Below 100 mg/dl is normal; 100 mg/dl to 125 mg/dl is considered pre-diabetes; over 126 mg/dl is considered diabetes.

Excess sugar in your blood damages blood vessels and leads to diabetes, which doubles women's risk for a first heart attack.

Ankle-Brachial Index

At least once a year ask your doctor to do this noninvasive test that compares the blood pressure in your feet with the one in your arms to make sure you're getting good blood flow throughout your body.

Blood pressure in your foot should be at least 90% of what it is in your arm.

If the blood pressure in your foot is much lower than in your arm, it's an indication that plaque is collecting in the arteries in your legs, a condition known as peripheral artery disease. And if there's plaque down there, it's a good bet it's in your coronary arteries as well.

Waist Circumference

At least once a month wrap a tape measure around your middle at your belly button. 

Take your height in inches, then divide by 2 to get your ideal waist measurement. If you're 5'4" (64 inches), your waist should be no bigger than 32 inches around.

Belly fat produces hormones that cause inflammation, damage organs, and promote insulin resistance. New studies show that when a woman of normal weight has a waist larger than 34.6 inches, her chance of stroke quadruples. And a wide middle coupled with elevated triglycerides nearly quadruples a woman's heart disease risk.
