It is estimated that one in four adults (approximately 50 million) in the United States has elevated blood pressure – and more than 30 percent of them are unaware of it. Since people with hypertension may not exhibit any symptoms, their high blood pressure is often undiagnosed until complications occur. It has been proven that blood pressure screening facilitates early diagnosis and treatment. Proper treatment clearly reduces the risk of the complications associated with hypertension. Blood pressure Blood pressure is the force exerted against artery walls as blood is carried through the circulatory system. The measurement of force is made in relation to the heart's pumping activity, and is measured in millimeters of mercury (mmHg). The higher number, or systolic pressure, is the measurement of pressure that occurs when the ventricle of the heart contracts or beats. The lower number, or diastolic pressure, is the measurement recorded between beats, while the heart is ...
There are times it is normal for the heart to beat harder, such as if you are out hiking and encounter a bear. Your blood pressure will jump so larger levels of oxygenated, nutrient rich blood is sent through your system and you are able to react. All part of the flight or fight response.
When you are diagnosed for high blood pressure your blood pressure is not just high for limited periods of time. It is consistently elevated. This means the heart is constantly working harder than it should.
Here are 7 reasons your heart may be dealing with this increased workload:
1. Atherosclerosis (narrowing of the arteries) - This may be caused by cholesterol deposits along arterial walls resulting in plaque buildup. Fibrosis or endothelial dysfunction may also result in narrower arteries. When arteries narrow the heart has to pump harder (exert more force) to move blood throughout the system.
2. Overweight and obesity - Fat is a tissue that requires a constant blood s...
<p><strong>What Is Hypertension? </strong></p>
<p>Hypertension (high blood pressure) is characterized by a persistent increase in the force that the blood exerts upon the walls of the arteries. It is normal for this force to increase with stress or physical exertion, but with hypertension, blood pressure is high even at rest.</p>
<p>Because blood pressure in the arteries rises and falls with each heartbeat, it is measured with two numbers: <strong>systolic</strong> (the top number in a reading) and <strong>diastolic</strong> (the bottom number). The systolic number reflects the force of blood against the arterial walls each time the heart contracts. Diastolic pressure refers to the pressure within the arteries as the heart relaxes and refills with blood (which explains why the diastolic number is always lower than the systolic measurement).</p>
<p>Blood pressure is measured in millimeters of mercury (abbr...
