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...
Alternative Names Accelerated hypertension; Arteriolar nephrosclerosis; Nephrosclerosis - arteriolar; Hypertension - malignant; High blood pressure - malignant Treatment You will need to stay in the hospital until the severe high blood pressure is under control. Medications will be given through a vein to reduce your blood pressure. If there is fluid in your lungs, you will be given medicines called diuretics, which help the body remove fluid. Your doctor will consider giving you medications to protect the heart if there is evidence of heart damage. After the severe high blood pressure is brought under control, blood pressure medicines taken by mouth can control the hypertension. Your medication may need to be adjusted occasionally. Hypertension can be difficult to control. Support Groups Expectations (prognosis) Many body systems are in serious risk due to the extreme rise in blood pressure. Multiple organs of the body, including the brain, eyes, blood vessels, heart, and kidneys may be dam...
