What you need to know about beta-blockers Beta-blockers are drugs that are used to slow down a person's heart rate. Doctors may prescribe them for a range of reasons, including angina and high blood pressure. There are many types and brands of beta-blockers, some of which affect other parts of the body. Learn about side effects, cautions, and interactions. Read now
A blood pressure reading measures both the systolic and diastolic forces, with the systolic pressure listed first. The numbers show your pressure in units of millimeters of mercury (mm Hg)—how high the pressure inside your arteries would be able to raise a column of mercury. For example, a reading of 120/80 mm Hg means a systolic pressure of 120 mm Hg and diastolic pressure of 80 mm Hg.

This study is assessing whether a low-sodium and low-calorie eating pattern, along with aerobic exercise, can improve blood pressure in patients who do not respond to high blood pressure medicines. To participate you must be at least 35 years and have high blood pressure that does not respond to medicines. Please note that this study is in Durham, North Carolina.
On physical examination, hypertension may be associated with the presence of changes in the optic fundus seen by ophthalmoscopy. The severity of the changes typical of hypertensive retinopathy is graded from I to IV; grades I and II may be difficult to differentiate. The severity of the retinopathy correlates roughly with the duration or the severity of the hypertension.
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.
It is notable that relaxation and meditation, though useful for many purposes, have not been found to impact high blood pressure. Many people find this surprising, possibly since high blood pressure also is known as “hypertension.” Because of this potentially misleading term, many people have assumed that high levels of stress or “tension” are a major cause of “hypertension,” or high blood pressure. This is not the case. High blood pressure is an essentially mechanical, and not psychological, problem.
Beta blockers decrease the effect of adrenaline on the cardiovascular system, slow the heart rate, and reduce stress on the heart and the arteries. Side effects include worsening shortness of breath if you have chronic obstructive pulmonary disease or asthma; sexual dysfunction; fatigue; depression; and worsening of symptoms if you have peripheral artery disease. Beta-blocker examples include:
Sodium (salt) sensitivity: Some people have high sensitivity to sodium (salt), and their blood pressure increases if they use salt. Reducing sodium intake tends to lower their blood pressure. Americans consume 10-15 times more sodium than they need. Fast foods and processed foods contain particularly high amounts of sodium. Many over-the-counter medicines also contain large amounts of sodium. Read food labels and learn about salt content in foods and other products as a healthy first step to reducing salt intake. Fast food restaurants also make the salt and calorie content of their food available to consumers at their restaurants,
