Blood Pressure

Blood pressure has gotten a bad rap. Some pressure is essential for circulation. Without it, blood couldn't move from the heart to the brain and the toes and back again. The heart provides the driving force — each contraction of the left ventricle, the heart's main pumping chamber, creates a wave of pressure that passes through all the arteries in the body. Relaxed and flexible arteries offer a healthy amount of resistance to each pulse of blood.

But too much of a good thing is a bad thing. Arteries that are tensed, constricted, or rigid offer more resistance. This shows up as higher blood pressure, and it makes the heart work harder. This extra work can weaken the heart muscle over time. It can damage other organs, like the kidneys and the eyes. And the relentless pounding of blood against the walls of arteries causes them to become hard and narrow, potentially setting the stage for a heart attack or stroke.

Most people with high blood pressure (known medically as hypertension) don't know they have it. Hypertension has no symptoms or warning signs. Yet it can be so dangerous to your health and well-being that it has earned the nickname "the silent killer." When high blood pressure is accompanied by high cholesterol and blood sugar levels, the damage to the arteries, kidneys, and heart accelerates exponentially.

High blood pressure is preventable. Daily exercise, following a healthy diet, limiting your intake of alcohol and salt, reducing stress, and not smoking are keys to keeping blood pressure under control. When it creeps into the unhealthy range, lifestyle changes and medications can bring it down.

Bad habits come in pairs

Couples often share health habits, whether good or bad, according to a recent study. When one partner doesn’t exercise regularly or eat a healthy diet, the other most often doesn’t either. Researchers found that in nearly 80% of cases, couples shared a high risk of developing heart-related problems because of shared risk factors. But the good news was that couples also seemed to influence each other in a positive direction. When one partner had good health habits, the other often did as well. (Locked) More »

3 supplements that may harm your heart

Some supplements pose risks to heart health. For example, red yeast rice supplements can amplify the effects of cholesterol-lowering medications. And garlic supplements can increase the levels and effects of some medications for heart health, such as blood thinners (causing bleeding), cholesterol-lowering drugs (causing muscle damage), and blood pressure drugs (causing dangerous drops in blood pressure). It’s important to talk to a doctor before trying any new supplement, and to ask if a supplement will interfere with a medication regimen. More »
