Calcium is needed by all muscle cells, including those of the heart and muscles and surrounding arteries, in order for the cells to contract. CCBs inhibit the movement of calcium into muscle cells. The reduction in calcium reduces the force of the heart's muscular pumping action (cardiac contraction) and thereby reduces blood pressure. These medications also relax the muscle cells surrounding the arteries to further reduce blood pressure. Three major types of calcium channel blockers are available. One type is the dihydropyridines, which do not slow the heart rate or cause other abnormal heart rates or rhythms (cardiac arrhythmias). They are commonly used for treating high blood pressure and are very effective in reducing blood pressure in African Americans.
When was the last time you thought about your blood pressure? If you're like most people, it probably hasn't been since your doctor mentioned it during your last checkup. But high blood pressure (hypertension) is a serious condition that can lead to life-threatening problems, like heart attack and stroke. The good news is that you can lower your risk of hypertension with lifestyle changes.
Exercise stress test: More commonly used for patients with borderline hypertension. This usually involves pedaling a stationary bicycle or walking on a treadmill. The stress test assesses how the body's cardiovascular system responds to increased physical activity. If the patient has hypertension this data is important to know before the exercise test starts. The test monitors the electrical activity of the heart, as well as the patient's blood pressure during exercise. An exercise stress test sometimes reveals problems that are not apparent when the body is resting. Imaging scans of the heart's blood supply might be done at the same time.
Lowering high blood pressure is as easy as one, two, tea: Adults with mildly high blood pressure who sipped three cups of hibiscus tea daily lowered their systolic BP by seven points in six weeks, found Tufts University researchers. The phytochemicals in hibiscus are probably responsible for the large reduction in high blood pressure, the study authors say.
Why stress happens and how to manage it Stress is essential for survival; the chemicals it triggers help the body prepare to face danger and cope with difficulty. Long-term stress is linked to various health conditions and can cause physical and psychological symptoms. How is it diagnosed, what types of stress are there, and how is it treated or managed?

High blood pressure, also known as hypertension (See blood pressure chart below) is called the “silent killer” for a reason — there are no obvious symptoms but it can result in heart attack, stroke and even death. The good news is there’s a lot you can do to maintain healthy blood pressure or get back to one, often without the need for medications.
Certain groups of people—the elderly, African Americans, and those with a family history of high blood pressure—are more likely than others to have blood pressure that's particularly salt-sensitive. But because there's no way to tell whether any one individual is at risk, everyone should consume less sodium, says Eva Obarzanek, PhD, a research nutritionist at the National Heart, Lung, and Blood Institute.
The causes are most often some combination of clogged “pipes” and excessive salt in the diet. Lifestyle changes, such as appropriate diet and exercise, are among the most effective treatment strategies for high blood pressure. Relaxation, meditation, and otherwise “taking it easy” are not effective solutions, as valuable as such strategies may be for your psychological well-being.
For some reason, health care providers often think of high blood pressure—or hypertension—as a "man's problem." More men have hypertension than women when they're younger, but once women reach menopause, their risk becomes greater than men's. Overall, about half of Americans with high blood pressure are women—and they're less likely to be diagnosed and treated for it.
