Resistant High Blood Pressure

Here we go again. First it was vitamin E. Then it was beta carotene. Now calcium supplements are being called on the carpet after researchers claimed they may do more harm than good. The flap comes in the wake of a German study that found a significantly increased risk of heart attack among women taking calcium supplements, but not among those who got their calcium from food. The study appears in the June 2012 issue of the journal Heart . Since calcium supplements are recommended to prevent osteoporosis for virtually everyone over age 50, this leaves millions of people wondering whether they should ditch their daily calcium pills. Three Harvard professors weigh in on the issue. Calcium and the heart Over time, calcium can accumulate in arteries. It makes them stiffer and less responsive to the demands of the body. Rigid arteries contribute to high blood pressure, angina (chest pain with exertion or stress), and heart failure. Calcium also builds up in plaque, the ch...

According to the American Health Association, an estimated 81 million Americans are affected by a least one form of cardiovascular disease. However, there is hope. In November 2011 US News & World Report ranked the DASH (Dietary Approaches to Stop Hypertension) diet the "healthiest diet to follow." The DASH diet is a balanced plan that research has demonstrated improved health by lowering blood pressure and cholesterol. While high blood pressure, which can lead to cardiovascular disease, cannot be cured, it can be prevented. A common but often overlooked culprit of high blood pressure is salt intake. The National Heart Lung and Blood Institute (NHLBI) advises less that 2.4 grams (2,400 milligrams) or 1 teaspoon, per day. The DASH diet is a low-salt (sodium) plan that emphasized eating fruits and vegetables, low-fat or no-fat milk products and whole grains. Research has shown that following the DASH diet can lower blood pressure in just 14 da...

Blood pressure is the force of blood against artery walls. It is measured in millimeters of mercury (mmHg) and recorded as two numbers—systolic pressure (when the heart beats) over diastolic pressure (when the heart relaxes between beats). Both numbers are important. Blood pressure rises and falls during the day. But when it stays elevated over time, then it's called high blood pressure. High blood pressure is dangerous because it makes the heart work too hard, and the high force of the blood flow can harm arteries and organs such as the heart, kidneys, brain, and eyes. High blood pressure often has no warning signs or symptoms. Once it occurs, it usually lasts a lifetime. If uncontrolled, it can lead to heart and kidney disease, stroke, and blindness. High blood pressure affects more than 65 million—or 1 in 3— American adults. About 28 percent of American adults ages 18 and older, or about 59 million people, have prehypertension, a condition that also increases the chance of he...

Blood pressure is the amount of force your blood exerts against the walls of your arteries. Normal blood pressure effectively and harmlessly pushes the blood from your heart to your body's organs and muscles so they can receive the oxygen and nutrients they need. Blood pressure is variable—it rises and falls during the day. When blood pressure stays elevated over time, however, it is called high blood pressure or hypertension. According to the most recent estimates, about 73 million Americans age 20 and older have hypertension and nearly half are women, according to the American Heart Association. High blood pressure killed nearly 54,707 Americans in 2004 and was listed as a primary or contributing factor in 300,000 deaths. Hypertension can occur in both children and adults, but it is more common in adults, particularly African Americans and the elderly. People with other conditions such as diabetes and kidney disease are likely to become hypertensive. In addition, ...
