Dr. Shiel received a Bachelor of Science degree with honors from the University of Notre Dame. There he was involved in research in radiation biology and received the Huisking Scholarship. After graduating from St. Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. He is board-certified in Internal Medicine and Rheumatology.
Stress reduction techniques such as biofeedback or transcendental meditation may be considered as an add-on to other treatments to reduce hypertension, but do not have evidence for preventing cardiovascular disease on their own. Self-monitoring and appointment reminders might support the use of other strategies to improve blood pressure control, but need further evaluation.
The first chemical for hypertension, sodium thiocyanate, was used in 1900 but had many side effects and was unpopular. Several other agents were developed after the Second World War, the most popular and reasonably effective of which were tetramethylammonium chloride, hexamethonium, hydralazine, and reserpine (derived from the medicinal plant Rauwolfia serpentina). None of these were well tolerated. A major breakthrough was achieved with the discovery of the first well-tolerated orally available agents. The first was chlorothiazide, the first thiazide diuretic and developed from the antibiotic sulfanilamide, which became available in 1958. Subsequently, beta blockers, calcium channel blockers, angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers, and renin inhibitors were developed as antihypertensive agents.
Your blood pressure is said to be “high” when either your systolic blood pressure is 140 or above, or your diastolic blood pressure is 90 or above, or both. So if your blood pressure is found to be 142/88 (systolic = 142, diastolic = 88), you are diagnosed as having high blood pressure, according to current definitions. The same would be true if your blood pressure was found to be 135/92, or 152/95. In each case, either the systolic is high, or the diastolic is high, or both. Any of these findings result in a diagnosis of high blood pressure.
For example, in a hypertensive patient with asthma, it may be inadvisable to prescribe a beta blocker, as these drugs can aggravate that respiratory condition. Similarly, in patients prone to constipation (the elderly, for example) use of certain calcium channel blockers might best be avoided -- along with diuretics -- as both these classes of drugs can inhibit proper bowel function.
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?

Some heart attacks are sudden and intense, however most heart attacks start slowly with mild pain and discomfort. Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness or pain. Shortness of breath may occur, as well as nausea, or lightheadedness. It is vital to get help immediately if any of these symptoms occur.
Instead of reaching for drugs, we should continue to find the most effective lifestyle interventions to help lower blood pressure and reduce cardiovascular risk without a laundry list of side effects. Unless, of course, you consider losing weight, having more energy, and feeling great as side effects — those are the type of side effects (from low-carb eating) that we all can embrace!
To make an official diagnosis of high blood pressure you will need to see your doctor. Often your blood pressure will be checked on at least two different visits, at different times of the day. Your doctor may ask you to keep a blood pressure log for a short time in order to see your overall blood pressure trends. If your blood pressure is consistently over 134/80, your doctor will work with you to determine the best regimen for treating your high blood pressure.
High blood pressure is a common and dangerous condition. Having high blood pressure means the pressure of the blood in your blood vessels is higher than it should be. But you can take steps to control your blood pressure and lower your risk of heart disease and stroke. About 1 of 3 U.S. adults—or about 75 million people—have high blood pressure.1 Only about half (54%) of these people have their high blood pressure under control.1 Many youth are also being diagnosed with high blood pressure.2 This common condition increases the risk for heart disease and stroke, two of the leading causes of death for Americans.3 Get more quick facts about high blood pressure, or learn more about high blood pressure in the United States.
Americans eat far too much dietary sodium, up to three times the recommended total amount, which is 1,500 milligrams (mg) daily for individuals with high blood pressure, says Dr. Fisher. It doesn't take much sodium to reach that 1,500-mg daily cap — just 3/4 of a teaspoon of salt. There's half of that amount of sodium in one Egg McMuffin breakfast sandwich. Weed out high-sodium foods by reading labels carefully. "It is very difficult to lower dietary sodium without reading labels, unless you prepare all of your own food," says Dr. Fisher. Beware in particular of what the American Heart Association has dubbed the "salty six," common foods where high amounts of sodium may be lurking:

Daily exercise: Being fit is a key part of blood pressure control. All kids with hypertension should exercise and play sports for 1 hour each day — with some activity (like jogging) most days and higher levels of activity (like running) 3 times a week. Usually, exercise is restricted only when hypertension is very severe. Kids with severe hypertension should not do any weight- or power-lifting, bodybuilding, or strength training until their blood pressure is under control and a doctor says it's OK.
For most people, the first-choice medication for high blood pressure is a thiazide diuretic. For other people, a diuretic alone is not enough to control blood pressure. In these cases, a diuretic may be combined with a beta-blocker, ACE inhibitor, angiotensin II receptor blocker, or calcium channel blocker. Adding a second medication may lower your blood pressure more quickly than using a diuretic alone. Also, it allows you to take less of each medication, which may reduce side effects.
Exercise could be just as effective in lowering high blood pressure as prescribed medication. Researchers pooled data from nearly 400 trials and found that for people with high blood pressure, activity such as walking, swimming and simple weight training seemed to be just as good as most drugs used to treat it. However, the team warns people should not stop taking their medication until further studies are carried out.
Hypertension, or high blood pressure, refers to the pressure of blood against your artery walls. Over time, high blood pressure can cause blood vessel damage that leads to heart disease, kidney disease, stroke, and other problems. Hypertension is sometimes called the silent killer because it produces no symptoms and can go unnoticed — and untreated — for years.
Oatmeal is one of a few semi-processed foods that lower blood pressure. That’s because getting the right amounts of dietary fiber and whole grains is vital to maintaining normal blood pressure, and oatmeal is a tasty source of both. Classic studies have proven that eating oatmeal can lower systolic and diastolic blood pressure. Plus, the fiber can help you maintain a healthy body weight and prevent obesity, a risk factor for high blood pressure. These are the 10 silent signs you could have low blood pressure.
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:
