Hypertension clinical guidelines from the American Heart Association are comprehensive guidelines for healthcare professionals for the detection and treatment of high blood pressure in a wide range of patients. Included in the 2018 hypertension clinical guidelines are proper methods for measuring blood pressure, risk factors for hypertension, and hypertension treatment for different populations.
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. 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.
There are a number of factors that likely work together to cause high blood pressure. A family history of high blood pressure can make you more likely to develop the condition, so genetics likely plays a role. High salt intake (too much salt in the diet) or salt sensitivity occurs in some people, which can lead to hypertension, particularly in the elderly, African Americans, people who are obese, or people with chronic kidney (renal) disease.
In most cases, the goal of treatment is to bring down the systolic pressure to less than 140 mm Hg and the diastolic pressure to less than 90 mm Hg. For people with diabetes, target blood pressure goals are lower (e.g., less than 130/80 mm Hg). For some people are who at high risk of cardiovascular complications such as stroke or heart attack, your doctor may recommend a systolic pressure target of less than 120 mm Hg. Your doctor will determine the most appropriate goal for you.
A nurse takes your blood pressure at your annual physical. The numbers are recorded and the checkup continues. But do you know where on the blood pressure chart your levels are? Are they healthy? Too low? Too high, meaning you have hypertension? If you have high blood pressure or are heading in that direction, you should know that hypertension is among the primary enlarged heart causes, and a major risk factor for heart failure.
