Hypertension is more than just elevated blood pressure. It comes with a set of risks that can cause damage to the heart, blood vessels and kidneys. Managing it, however, isn’t as hard as you think.
Allowing high blood pressure to go unmanaged carries a variety of risks including atherosclerosis, when fatty plaques thicken and harden inside arteries; blood vessels can become damaged and dysfunctional, blood clots can occur, and it greatly enhances risk for stroke and heart attack.
It can even cause the heart to remodel and become fibrotic, in which heart tissue is replaced with non-functional scar tissue. This can lead to congestive heart failure and other types of heart disease. Those with hypertension also are more likely to have diabetes since the risk factors are similar.
However, getting your blood pressure back on track isn’t as difficult as it may sound. Often, it’s just a matter of dedication and determination.
Those with high blood pressure must commit to serious long term lifestyle changes to reap the benefits. But it’s entirely possible for those ready to make the changes.
Cutting the Risk
Though dropping blood pressure requires substantial changes, even small gradual steps can be immensely helpful. Dr. Howard Weintraub, a cardiologist and clinical director for the New York University Center for the Prevention of Cardiovascular Disease, said that even a small reduction in blood pressure can reduce risk of heart attack and blood vessel damage by about 9 percent.
“When we think of hypertension, we now think of it as one of a host of cardiovascular risk factors,” Dr. Weintraub said. “If there is high blood pressure, we also check blood sugars and cholesterol and so forth.”
Blood pressure measures the force pushing outward on arterial walls. The top number, or systolic, measures pressure in the arteries when the heart beats, while the bottom number, or diastolic, measures the pressure in arteries between heartbeats. A normal blood pressure should include a systolic number no higher than 120 and diastolic number that is no higher than 80, according to the American Heart Association.
About 76 million American adults currently have high blood pressure, about a third of the population over the age of 18. Over half of hypertensive patients also are overweight.
Patients should be screened regularly, preferably at each check up. According to the American Heart Association, at least 20 percent of those who suffer from hypertension are not aware of it. Knowing whether you have the condition could aid in taking steps to avoid serious health risks.
If there is a diagnosis of hypertension, following doctors orders for lowering it are critical. The American Heart Association reports that 31 percent of individuals who are hypertensive are not currently under treatment even though they are aware that their blood pressure is too high.
Lowering the Numbers
“If you’re dealing with the typical couch potato who has gained 20 to 30 pounds over the last decade, has a family history of hypertension, and eats too much salt and bad foods, getting them to improve the foods they are eating can be considerably important,” Dr. Weintraub said.
“But perseverance is a big issue. Regrettably, a number of adults we see have eaten and misbehaved their way into becoming too heavy. Then when it comes down to it there’s this syndrome of weddings and holidays and weekends. Then the eight to 10 pounds they lost comes back, and they just don’t bother.”
He suggests avoiding excessive quantities of fatty red meats. Skip saturated fats and trans fats, instead choosing fruits, vegetables, whole grains, fish and lean meats. Also avoid salt and limit sugar.
In addition, individuals should exercise regularly, maintain a healthy weight, manage stress and quit smoking. It also is best to limit alcohol consumption.
“Others just lose the weight that was prescribed, and then stop at McDonald’s. That’s why it’s so hard. You’re not putting them on a diet, you’re asking them to change their lifestyle,” Dr. Weintraub said.
Many patients may need medication in addition to lifestyle changes to manage their hypertension. Most take several medications, including beta blockers to reduce nerve impulses to the heart and blood vessels, angiotensin converting enzyme (ACE) inhibitors, which prevents formation of a blood vessel narrowing hormone; alpha blockers to reduce nerve impulses to blood vessels and nervous system inhibitors, which relax blood vessels.
Other medications include diuretics to flush the kidneys of excess water, angiotensin antagonists to help widen blood vessels, calcium channel blockers to stop calcium from entering muscle cells of the heart and blood vessels, alpha-beta blockers, which work like alpha blockers but also slow the heart rate, and vasodilators, which open blood vessels.
