For people over 60, aiming for a blood pressure target below 130/80 mm Hg may prevent more cardiovascular problems than aiming for the higher target suggested by some physicians. Some feared that the more intensive treatment required to reach the lower target might cause more adverse side effects (such as dizziness and falls) in older people. But side effects do not appear to differ among people taking intensive versus standard therapy.

For many people, non-HDL cholesterol (which is total cholesterol minus HDL cholesterol) may be as good as (or even more reliable than) LDL for assessing a person's risk of heart problems.

When it comes to under-the-radar health conditions, deep-vein thrombosis is at the top of the list. Most of my patients have never heard of this common problem. Yet deep-vein thrombosis puts more than one-quarter million Americans in the hospital each year, and complications from it are responsible for upwards of 100,000 deaths.

Blood pressure is the push of blood through the body, like water through a hose. Pressure depends on how hard the heart pumps, how much blood there is, and how tight small vessels are, all influenced by hormones, salt, fluids, and stress.

Many home blood pressure monitors are not validated for accuracy, which means there's no way to know if information they provide is correct. Relying on inaccurate measurements can affect decisions people make about medical treatment. Fortunately, reliable organizations have developed lists of blood pressure monitors that have demonstrated clinical accuracy. If a blood pressure monitor isn't listed, it's probably not validated.

Pregnancy complications such as gestational diabetes and preeclampsia—marked by high blood pressure that can impair organ function and affect blood vessels—are increasingly tied to higher lifetime cardiovascular risks. Women with these complications face greater odds of heart attack, stroke, and diabetes.

Statin dosages fall into three categories (low, moderate, or high) based on how much the medication can lower LDL. The choice of a statin depends on a person's risk.

There are other conditions besides arthritis that can make walking difficult and even painful, such as peripheral artery disease, chronic venous insufficiency, lumbar spinal stenosis, and diabetic neuropathy.

People with elevated LDL cholesterol values may be able to reduce their LDL levels by eating more foods that are rich in fiber and lower in saturated fats. High-fiber foods include whole grains, beans, nuts, vegetables, and fruits. Saturated fats are found mainly in meat, cheese, and other high-fat dairy products such as butter, half and half, and ice cream.
