Pulse pressure (the difference between systolic and diastolic blood pressure) is frequently increased in older people with hypertension. This can mean that systolic pressure is abnormally high, but diastolic pressure may be normal or low a condition termed isolated systolic hypertension.[59] The high pulse pressure in elderly people with hypertension or isolated systolic hypertension is explained by increased arterial stiffness, which typically accompanies aging and may be exacerbated by high blood pressure.[60]
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.[125][126][127] Self-monitoring and appointment reminders might support the use of other strategies to improve blood pressure control, but need further evaluation.[128]
If your blood pressure remains high for a long period of time, you run the risk of damaging your blood vessels. Your stroke risk rises significantly, too. And because your heart is working harder to push blood through your system, that very valuable muscle can become overworked and grow thicker. An enlarged heart causes further complications, including heart failure. Medications and special implantable pumps can help boost heart function. But if you can manage your blood pressure before it gets too high and puts your heart at risk, you may be able to avoid a lot of complications down the road.
When a direct cause for high blood pressure can be identified, the condition is described as secondary hypertension. Among the known causes of secondary hypertension, kidney disease ranks highest. Hypertension can also be triggered by tumors or other abnormalities that cause the adrenal glands (small glands that sit atop the kidneys) to secrete excess amounts of the hormones that elevate blood pressure. Birth control pills -- specifically those containing estrogen -- and pregnancy can boost blood pressure, as can medications that constrict blood vessels.

The World Health Organization has identified hypertension, or high blood pressure, as the leading cause of cardiovascular mortality.[162] The World Hypertension League (WHL), an umbrella organization of 85 national hypertension societies and leagues, recognized that more than 50% of the hypertensive population worldwide are unaware of their condition.[162] To address this problem, the WHL initiated a global awareness campaign on hypertension in 2005 and dedicated May 17 of each year as World Hypertension Day (WHD). Over the past three years, more national societies have been engaging in WHD and have been innovative in their activities to get the message to the public. In 2007, there was record participation from 47 member countries of the WHL. During the week of WHD, all these countries – in partnership with their local governments, professional societies, nongovernmental organizations and private industries – promoted hypertension awareness among the public through several media and public rallies. Using mass media such as Internet and television, the message reached more than 250 million people. As the momentum picks up year after year, the WHL is confident that almost all the estimated 1.5 billion people affected by elevated blood pressure can be reached.[163]
A blood pressure reading contains two numbers: systolic pressure and diastolic pressure. Systolic pressure is the top or first number in your blood pressure reading; it indicates the pressure within your arteries when your heart pumps out blood. Diastolic pressure is the bottom number, and shows the pressure in your arteries while your heart is filling with blood.

It is normal that blood pressure fluctuates during the day. Consecutive measurement will show a circadian rhythm over a 24-hour period. Usually highest reading will be observed in the morning, while lowest readings will be observed in the evening or during the night, when body is at rest. It is also important to note that blood pressure values may be affected by adrenaline, emotions, exercise, sleep patterns and digestion so make sure you pick a good time to do the screening, or otherwise your measurements will not be accurate. It is advisable to repeat the measurement up to three times in a row (with a pause of few minutes in between) to establish a correct value.
When blood pressure is measured, there are two numbers for each reading: for example, "120 over 80" is written as 120/80. This is because each heartbeat sends a pressure wave through the bloodstream. The higher number (systolic blood pressure) is the peak of the wave, when your heart contracts (the loud "thump" when you listen to your heartbeat). The lower number (diastolic blood pressure) is the lower "dip" or trough of the wave, when your heart relaxes.
Unfortunately, this seems like a common scenario — medical guidelines recommend more aggressive medication use for minimal potential benefit despite potential harm. A new study published in the Journal of the American Medical Association (JAMA), suggests the blood pressure guidelines go too far for low risk individuals, and the risk of harm outweighs the potential benefits.
Recently, I started to culture A549 cells. The cell looks very well at the other day after thawing, but it grows extremely slowly while culturing. They become large and flat and look like senescence. I thought it might be mycoplasma contamination, but the medium is clean and without any visible black dots. And also I added ciprofloxacin to the medium to inhibit mycoplasma, but it is not helpful. I tried both 1640 and DMEM medium supplemented with 10% FBS, 10mM Hepes, 1% PS (according to the experience of other labs, both medium is suitable for A549). There is no improvement. How can I change this situation? Does it need any additional supplement, cytokines or growth factors?
Other exercise options that don’t require a gym membership include body weight exercises, like pushups, squats, and jumping jacks. These exercises can be done at home or outside. For people who like going to the gym or running, these can be good ways to build community, notes Parker. Apps like Fitbit and MapMyRun can be helpful if you like keeping track of your steps, calories burned, weight, or number of miles run.
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.
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!

In this article, we will describe the kinds of drugs that are used for hypertension, and what steps your doctor should take in choosing (from the incredible array of options) your optimal treatment. Finally, we will provide a reasonably complete list of all the drugs currently used in the U.S. (and in most developed countries) for the treatment of hypertension.
Dietary changes: The health care provider might recommend a diet that includes more vegetables (especially leafy green vegetables), fruits, low-fat dairy products, and fiber-rich foods, and fewer carbohydrates, fats, processed foods, and sugary drinks. He or she also might recommend preparing low-sodium dishes and not adding salt to foods. Watch out for foods with lots of hidden salt (like bread, sandwiches, pizza, and many restaurant and fast-food options).

According to the Centers for Disease Control and Prevention (CDC), an estimated 75 million Americans have high blood pressure. Many risk factors for high blood pressure are out of your control, such as age, family history, gender, and race. But there are also factors you can control, such as exercise and diet. A diet that can help control blood pressure is rich in potassium, magnesium, and fiber and lower in sodium.
For obese people or people with family history of high blood pressure, you need to watch your blood pressure. Your total blood pressure reading is determined by measuring your systolic and diastolic blood pressures. Systolic BP, the top number, measures the force your heart exerts on the walls of your arteries each time it beats. Diastolic BP, the bottom number, measures the force your heart exerts on the walls of your arteries in between beats. Below is a blood pressure chart by age.

High blood pressure is classified as either primary (essential) high blood pressure or secondary high blood pressure.[5] About 90–95% of cases are primary, defined as high blood pressure due to nonspecific lifestyle and genetic factors.[5][6] Lifestyle factors that increase the risk include excess salt in the diet, excess body weight, smoking, and alcohol use.[1][5] The remaining 5–10% of cases are categorized as secondary high blood pressure, defined as high blood pressure due to an identifiable cause, such as chronic kidney disease, narrowing of the kidney arteries, an endocrine disorder, or the use of birth control pills.[5]
The guidelines also say that a patient's blood pressure levels should be based on an average of two to three readings on at least two different occasions. It's also reasonable for doctors to screen for "white-coat hypertension," which occurs when blood pressure is elevated in a medical setting but not in everyday life, the authors said. This can be done by having patients measure their blood pressure at home.
