Blood pressure is the measure of the force of blood pushing against blood vessel walls. The heart pumps blood into blood vessels, which carry the blood throughout the body. High blood pressure, also called hypertension, is dangerous because it makes the heart work harder to pump blood out to the body and contributes to hardening of the arteries, or atherosclerosis, to stroke, kidney disease, and to heart failure.
Trans fat: A type of unhealthy fat that’s created through a food processing method called partial hydrogenation. It’s often found in store-bought cookies, crackers, cakes, and many fried foods. Experts consider it to be one of the worst fats, because it raises LDL (bad) cholesterol levels and lowers HDL (good) cholesterol levels, increasing the risk of heart disease. Avoid trans fats as much as possible.
One reason to visit your doctor regularly is to have your blood pressure checked. Routine checks of your blood pressure will help pick up an early rise in blood pressure, even though you might feel fine. If there's an indication that your blood pressure is high at two or more checkups, the doctor may ask you to check your blood pressure at home at different times of the day. If the pressure stays high, even when you are relaxed, the doctor may suggest exercise, changes in your diet, and, most likely, medications.
Physical examination may include listening to the heart and lungs, feeling for pulse in the wrist and ankles, and feeling and listening to the abdomen looking for signs of an enlarged aorta. The examiner may also listen in the neck for carotid bruits (sounds made by a narrowed artery in the neck) and in the abdomen for bruits made by an abdominal aortic aneurysm.
Though essential hypertension remains somewhat mysterious, it has been linked to certain risk factors. High blood pressure tends to run in families and is more likely to affect men than women. Age and race also play a role. In the United States, blacks are twice as likely as whites to have high blood pressure, although the gap begins to narrow around age 44. After age 65, black women have the highest incidence of high blood pressure.
Contemporary science shows an immersed boundary method of computational illustration of a single heartbeat. Applied to physiologic models, immersed boundary theory sees the heart as a great folded semisolid sail fielding and retrieving a viscous blood mass. The sail, likened to Windkessel effect physiology, gives and receives a load under time-ordered phases. Decreasing compliance of the sail heralds the onset of systolic hypertension.
Fruits offer lots of fiber and vitamins that are good for your heart. Many also have potassium and magnesium, which lower blood pressure. Have four to five servings of fruit every day. One serving is a medium apple or orange, or 1/2 cup of frozen, fresh, or canned fruit. One-half cup of fruit juice or 1/4 cup of dried fruit also counts as a serving. Try adding bananas or berries to your breakfast cereal or have fruit for dessert.
