Peripheral artery disease, or PAD, develops when fat, or plaque, builds up inside the arteries similarly to the way blood vessels of the heart become blocked, which can lead to a heart attack. Over time, this fat can block blood flow to the brain, arms, kidneys, or legs, resulting in pain, disability, and, in some cases, even amputation of the foot or leg.

People are at high risk for PAD if they smoke; have diabetes, high blood pressure, or high cholesterol; do not exercise; do not eat a variety of nutritious foods; or are over the age of 65. African-Americans, Hispanic-Americans, and Native Americans are at higher risk for PAD.

Walking at least 30 minutes a day can help prevent the build-up of plaque in arteries. Eating five to 10 servings of fruits and vegetables a day and limiting red meat to once or twice a week can also lessen your chances of developing peripheral artery disease. If you smoke, now is the time to stop. Control your weight, blood pressure, and blood sugar.

Some people have warning signals of dangerous plaque build-up, such as pain and leg cramps when walking. Many people do not have symptoms. Fortunately, we don't have to wait for symptoms, because PAD can frequently be detected through a simple test called the "ankle-brachial index" exam. With this information and help from your doctor, steps can be taken to correct the problem before it progresses too far. Treatment for PAD can involve exercise, medication, and surgery.

The Johnson County Health Department will screen for peripheral artery disease throughout this year for those over 60. The ankle-brachial index exam takes 20 to 30 minutes. The exam requires you to lie flat for 10 minutes; then blood pressures will be taken in both arms and both ankles. The exam providers will go over your results with you and discuss life changes you can make to improve or prevent peripheral artery disease.

PAD screenings are offered from 9:00 a.m. to noon the first Wednesday of each month. The screening clinics will take place at the Mission Health Department, 6000 Lamar Ave., on the first Wednesday in June and October. Other months, the site will be the Olathe Health Department, 11875 S. Sunset Drive.

In an effort to keep waiting to a minimum, screenings will be done by appointment only. Call Carey Yale, 913-477-8333, to make an appointment. All clinics have been full so far this year, so call for your appointment today.

The Johnson County Health Department thanks the Johnson County Area Agency on Aging for its continued funding support for these screenings.
