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...
Hypertension is blood pressure that is often higher than 140/90 millimeters of mercury (mm Hg).
HBP; Blood pressure - high
Blood pressure can vary throughout the day and change with activity. A blood pressure measurement has two numbers:
The top (systolic) number is the blood pressure during the heartbeat.
The bottom (diastolic) number is the blood pressure between beats.
According to the American Heart Association, adults should normally have a blood pressure less than 120/80 mm Hg.
Pre-hypertension is when the top number is 120-139 mm Hg and the bottom number is over 80-89 mm Hg on most measurements. If you have pre-hypertension, you are likely to develop high blood pressure at some time in your life, unless you make lifestyle changes.
High blood pressure can affect all types of people. You have a higher risk of high blood pressure if you have a family history of the disease. High blood pr...
Let’s first take a look at what drives your blood pressure. Unlike a river, which flows continuously downstream, blood flow is pulsatile, with ebb and flow driven by pumping heart muscle. This cycle repeats itself 60 or so times each minute, every time your heart beats. With each heartbeat occurring about once per second, the heart squeezes, or contracts, within a split-second. The rapid contraction forces about 90 cc of blood (approximately 1/3 cup) up, pushing the aortic valve open, and blood passes up into the aorta and rapidly distributes upward to the brain (via the carotid arteries on either side of the neck), the arms, and downward to the abdomen, pelvis, and legs. The force of heart contraction and its rapid distribution to the body is measured as systolic pressure, or the top number in blood pressure. As the 90 cc or so of ejected blood distributes rapidly throughout the body, pressure in all the arteries drops over the ensuing half second, and the aortic valve closes. Th...
