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.

Get your heart pumping in the fight against forgetfulness

Regular moderately intense exercise up to 150 minutes per week releases brain chemicals that support better memory, concentration, and mental sharpness. Exercise also maintains healthy blood pressure and weight, helps you feel more energetic, lifts your mood, lowers stress and anxiety, and keeps your heart healthy. To get the most brain benefit, exercise regularly to get your heart rate up to 70% of maximum. To succeed at exercise, do it with a partner, outdoors, and in a way that is fun for you. More »

RX for heart failure: coffee

Drinking two cups of coffee a day may protect against heart failure, likely by lowering the risk of high blood pressure and diabetes. (Locked) More »

High blood pressure a silent danger in postmenopausal women

Nearly a third of American adults have high blood pressure, half of whom don’t have their blood pressure under control—despite most of them having a doctor and health insurance. Forty percent of people with uncontrolled high blood pressure aren’t aware they have the condition. It’s crucial to treat blood pressure, because it can lead to heart disease, stroke, heart attack, kidney disease, and other health issues if left unchecked. Treatment usually starts with one or more blood pressure medications, along with lifestyle interventions such as diet and exercise. More »

Prevent peripheral artery disease

Peripheral artery disease has four main risk factors: smoking, high cholesterol, high blood pressure, and type 2 diabetes. The more risk factors one accumulates, the higher the risk, and the severity of risk factors increases risk. Developing all four of the risk factors can increase PAD risk to 75%. Avoiding all four risk factors can eliminate many cases of PAD before they start. Treating PAD involves quitting smoking; controlling diabetes, high cholesterol, and high blood pressure; and sometimes surgery to improve blood flow. (Locked) More »

Chelation for heart disease

Many people try chelation therapy for a variety of reasons, but it is unproven and potentially risky as a therapy for heart disease. Instead, use proven measures like daily aspirin, exercise, blood pressure control, and lowering "bad" cholesterol. (Locked) More »

New thinking about stable heart disease

People with stable heart disease are at low risk for heart attack and may not need invasive treatment until significant chest pain is no longer relieved by medication. At this point, the risk of heart attack is greater, and coronary artery bypass surgery or angioplasty should be considered. (Locked) More »

Treating resistant hypertension

When a diuretic plus two other anti-hypertensive medications fail to lower blood pressure to an acceptable level, additional medications should be added until blood pressure responds. Restricting salt and increasing exercise can often help conquer “resistant hypertension.”   (Locked) More »
