Hypertension is when the systolic pressure exceeds 140 mmHg or even if diastolic exceeds 90 mmHg. Hypertension occurs when the blood vessels walls become thicker and less elastic, which causes less blood and oxygen to flow to all body systems. When the blood vessels become more constricted due to the loss of elasticity peripheral vascular resistance begins to increase causing more pressure to occur within the vessel walls. With more pressure and blood vessels becoming more constricted, less blood can reach all systems of the body as the heart is working harder to pump blood. Hypertension affects all body systems, hypertension affects the cardiovascular system as the thickening of the arteries causes more pressure to build up in the walls
As the blood is forced throughout our body, there is a pressure that is exerted on the walls of our arteries, this is known as blood pressure. We see blood pressure represented as two numbers, the systolic (top) and the diastolic (bottom) numbers. The systolic blood pressure is the heart contracting and the diastolic is the heart relaxing. A normal, healthy, blood pressure would be written as 120/80 mmHg (millimeters of mercury) or verbally expressed by most individuals as 120 over 80. Our blood pressure can vary depending on many things. When the diastolic or systolic pressure is high, or significantly and consistently above 120/80 mmHg, this is what we call hypertension. There are different stages or degrees of hypertension. Lippincott Williams and Wilkins (2010) describes the stages as the following:
Hypertension (HTN) is a chronic cardiovascular condition that is characterized by high blood pressure. The blood pressure commonly abbreviated as BP is a measure of the force exerted on the blood vessels as the blood passes through them. The amount of blood pumped and the narrowness of ones’ vessels are directly proportional to the blood pressure (Mayoclinic staff, 2014).
Many people find out about hypertension only when they suffer a heart attack or get a medical check-up done. Hypertension is a life-threatening condition characterized by high blood pressure in the arteries leading to the lungs and heart. Unlike regular hypertension or high blood pressure, hypertension occurs when the arteries in the lungs become blocked or narrow, making it harder for the heart to pump blood through them. This raises blood pressure in the lungs and causes the heart to weaken, which may eventually lead to heart failure. Hypertension is also dangerous because it can lead to strokes, heart attacks, heart failure, or kidney disease. So the goal of hypertension treatment is to lower high blood pressure and protect important organs, like the brain, heart, and kidneys from damage.
A hypertensive heart has thickened ventricular walls which make the heart work harder to pump the blood throughout the body. When the walls thicken, the elasticity is decreases and the heart and other systems need to work harder to pump oxygenated blood throughout the body.
High blood pressure has many damaging effects on the heart. High blood pressure is known as a silent killer and if left untreated can cause serious damage to the heart. What causes high blood can differ from person to person. What causes this for some may be different with another. Genetics, diet, family history, weight, and use of salt are just some of the causes of high blood pressure. Some of the ways that high blood pressure damages the heart is through narrowing of the arteries in the heart, called arteriosclerosis, left ventricular hypertrophy, and restricted blood flow that can lead to strokes and heart attacks. High blood pressure can have damaging effects on the heart if left untreated, and can cause arteriosclerosis, left ventricular hypertrophy, and restricted blood flow that leads to strokes and heart attacks.
Ans: Over a long period of time, the increased blood pressure increases work for the heart causing left-side heart failure, damage to cerebral arteries causing stroke, damage to
Hypertension is defined as the amount of pressure blood flow exerts into the arteries. This becomes a problem because hypertension ultimately puts an added force against the walls of the arteries making them more susceptible to not only narrowing of the artery walls but to plaque build-up as well. The added force associated with hypertension also begins to diminish the elasticity and strength of the artery walls which limits the amount of blood flow that can reach the myocardium.
Thousands of babies are born a day in the United States. One out every 691 babies born has Down syndrome, a disorder caused by an extra copy of the chromosome twenty one. In short, this syndrome shortens the person’s life span, and causes assorted severity of mental retardation. Those carrying this extra chromosome have flattened noses, rounder faces, are petite in size, and are much more prone to additional unhealthy disturbances or effects on substantial systems in the body.
Conditions such as hypertension and coronary artery disease cause an increase in blood pressure. Blood pressure increases when arteries become narrow as a result of hardening or due to build up of fat deposits; both of which are major
Etiology – Hypertensive heart disease is associated with high blood pressure related to the heart's arteries and muscles. Blood is transported to the heart by coronary arteries. High blood pressure causes blood vessels to become narrow which can cause the blood flow to the heart to slow and even stop. Sometimes blood clots form and get stuck in the narrowed arteries and put the person at serious risk of a heart attack.
The pressure hypertension is caused by a narrowing of small arteries called "arteriola" (regulate the blood flow in the organism). As the
Basically, arterial blood pressure (BP) is directly proportional to the product of blood flow (cardiac output, CO) and the resistance to passage of blood through pre-capillary arterioles (peripheral vascular resistance, PVR) Hypertension can be caused by either an increase in Cardiac Output (CO) or by an increase in Peripheral Resistance (PR)
One of the most important systems in the body, keeping it alive, is the cardiovascular system. As a part of the circulatory system, the cardiovascular system pumps blood throughout the body through a network of many arteries and veins, providing it with nutrients and oxygen. Also, the cardiovascular fights infections and disease in the body and creates blood cells. Never the less, blood acts as a filtration system for the body and removes waste, cell debris, or bacteria from the bloodstream.
Hypertension is defined a consistent elevation of the systolic blood pressure above 140mmHg, a diastolic pressure above 90mmHg or a report of taking antihypertensive medication. Early diagnosis and effective management of hypertension is essential because it is a major modifiable risk factor to cerebrovascular, cardiac, vascular, and renal diseases. The higher the blood pressure, the greater the risk for heart attack, heart failure, stroke, and kidney disease.
Hypertension is the medical term for high blood pressure. A normal blood pressure is 120/80. A blood pressure reading higher or equal to 140/90 is considered abnormally high. Elevated blood pressure means your heart is working harder than normal, putting both your heart and arteries under great strain. High blood pressure is serious business.
