High blood pressure, or hypertension, is a major health problem that is common in older adults. Your body’s network of blood vessels, known as the vascular system, changes with age. Arteries get stiffer, causing blood pressure to go up.4
Blood pressure is the force of blood flowing through a person’s blood vessels. Doctors calculate a person’s blood pressure using two measurements known as systolic and diastolic. Systolic blood pressure is the highest level of force at which the heart pumps blood around the body.
Among the various causes of blood pressure in the elderly population, isolated systolic hypertension (ISH) is the commonest. Its prevalence increases with age. Age related rigidity of aorta is the primary cause of ISH. Systolic rise in blood pressure is at least as important as the diastolic blood pressure.
When your blood is being actively pushed into your arteries during systole, the pressure in the arteries increases. The peak blood pressure during a heart contraction is called systolic. The pressure exerted on the blood vessels between heartbeats is called diastolic.
Blood pressure is measured using two numbers: The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats. The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.
Systolic pressure is affected by a variety of factors. Factors such as anxiety, caffeine consumption, and performing resistance and cardiovascular exercises, cause immediate, temporary increases in systolic pressure.
Systolic hypertension is an expression of increased arterial stiffness, especially of the large arteries. Adequate antihypertensive therapy in the elderly will significantly reduce cardiovascular morbidity and mortality. The blood pressure goal in the very elderly is 150/80 mmHg.
Here are 17 effective ways to lower your blood pressure levels.
Systolic: The blood pressure when the heart is contracting. It is specifically the maximum arterial pressure during contraction of the left ventricle of the heart. The time at which ventricular contraction occurs is called systole.
Effective Writing for Health Care Over the years, research has found that both numbers are equally important in monitoring heart health. However, most studies show a greater risk of stroke and heart disease related to higher systolic pressures compared with elevated diastolic pressures.
Anxiety doesn’t cause long-term high blood pressure (hypertension). But episodes of anxiety can cause dramatic, temporary spikes in your blood pressure.
With increasing systolic pressure women also reported more headaches, unsteadiness, blurring of vision, irregular heart beat and ‘racing heart’ but, of these, only headaches increased with diastolic pressure.
Diastole and systole are two phases of the cardiac cycle. They occur as the heart beats, pumping blood through a system of blood vessels that carry blood to every part of the body. Systole occurs when the heart contracts to pump blood out, and diastole occurs when the heart relaxes after contraction.
Clearly, this is a small percentage, but not an insignificant number. When treating hypertension in patients over the age of 85 years, the usual target blood pressure is 150/80 mmHg for reduction of the risk of stroke, heart attack, and other cardiovascular events.
Dihydropyridine-type calcium channel blockers and thiazide-like diuretics are preferred first-line agents. Angiotensin-converting enzyme inhibitors/angiotensin receptor blockers can be used when compelling indications are present. Beta-blockers should be avoided.
