INTRODUCTION
HYPERTENSION
Hypertension (HTN) or high blood pressure is common disorder that is a
known cardiovascular disease risk factor, characterized by elevated blood
pressure over the normal values of 120/80 mm Hg in an adult over 18 years of
age. This elevation in blood pressure can be divided into three classes of
hypertension.
Prehypertension describes blood pressure measurements of greater than
120 mm Hg systolic or 80 mm Hg diastolic and less than 130 mm Hg systolic or
90 mm Hg diastolic. Persons exhibiting prehypertension are encouraged to
explore life-style modifications to lower blood pressure, but blood-pressure
lowering agents are not generally prescribed without compelling indications.
The second classification of hypertension is Stage 1 hypertension and is
defined by a blood pressure of over 130 mm Hg systolic or 90 mm Hg diastolic
but less than 160 mm Hg systolic or 100 mm Hg diastolic. Patients with Stage 1
hypertension are also encouraged to make life-style modifications, and initial
drug therapy may include thiazide-type diuretics, ACE inhibitors, calcium channel
blockers, beta blockers, and angiotensin-receptor blockers, or a combination of
these.
Stage 2 hypertension is defined by a blood pressure greater than 160 mm
Hg systolic or 100 mm Hg diastolic. Persons with Stage 2 hypertension are
encouraged to make life-style modifications. Two-drug combination therapies (of
thiazide-type diuretics, ACE inhibitors, calcium channel blockers, beta blockers,
and angiotensin-receptor blockers) are indicated for these patients.
Essential hypertension, the most common kind, has no single identifiable
cause, but risk for the disorder is increased by obesity, a high serum sodium
level, hypercholesterolemia, and a family history of high blood pressure. Known
causes of secondary hypertension include sleep apnea, chronic kidney disease,
primary aldosteronism, renovascular disease, chronic steroid therapy, Cushing's
syndrome, pheochromocytoma, coarctation of the aorta, and thyroid or
parathyroid disease.
The incidence of hypertension is higher in men than in women and is twice
as great in African-Americans as in Caucasians. People with mild or moderate
hypertension may be asymptomatic or may experience suboccipital headaches,
especially on rising; tinnitus; lightheadedness; ready fatigability; and palpitations.
With sustained hypertension, arterial walls become thickened, inelastic, and
resistant to blood flow, and the left ventricle becomes distended and
hypertrophied as a result of its efforts to maintain normal circulation against the
increased resistance. Inadequate blood supply to the coronary arteries may
cause angina or myocardial infarction. Left ventricular hypertrophy may lead to
congestive heart failure. Malignant hypertension, characterized by a diastolic
pressure higher than 120 mm Hg, severe headaches, blurred vision, and
confusion, may result in fatal uremia, myocardial infarction, congestive heart
failure, or a cerebrovascular insult. Patients with high blood pressure are advised
to follow a low-sodium, low-saturated-fat diet; to control obesity by reducing
caloric intake; to exercise; to avoid stress; and to have adequate rest.

ANATOMY AND PHYSIOLOGY
CENTRAL NERVOUS SYSTEM
Medulla Oblongata; relays motor and sensory impulses between other parts of the brain and the spinal cord. Reticular formation (also in pons, midbrain, and diencephalon) functions in consciousness and arousal. Vital centers regulate heartbeat, breathing (together with pons) and blood vessel diameter.
Hypothalamus; controls and integrates activities of the autonomic nervous
system and pituitary gland. Regulates emotional and behavioral patterns and
circadian rhythms. Controls body temperature and regulates eating and drinking
behavior. Helps maintain the waking state and establishes patterns of sleep.
Produces the hormones oxytocin and antidiuretic hormone.
CARDIOVASCULAR SYSTEM
Baroreceptors, pressure-sensitive sensory receptors, are located in the aorta,
internal carotid arteries, and other large arteries in the neck and chest. They
send impulses to the cardiovascular center in the medulla oblongata to help
regulate blood pressure. The two most important baroreceptor reflexes are the
carotid sinus reflex and the aortic reflex.
Chemoreceptor, sensory receptors that monitor the chemical composition of
blood, are located close to the baroreceptors of the carotid sinus and the arch of
the aorta in small structures called carotid bodies and aortic bodies, respectively.
These chemoreceptor detect changes in blood level of O2, CO2, and H+.
Heart. The main functions of the heart can be summarized as follows: The right-
hand side of the heart receives de-oxygenated blood from the body tissues (from
the upper- and lower-body via the Superior Vena Cava and the Inferior Vena
Cava, respectively) into the right atrium. This de-oxygenated blood passes
through the tricuspid valve into the right ventricle. This blood is then pumped
under higher pressure from the right ventricle to the lungs via the pulmonary
artery The left-hand side of the heart receives oxygenated blood from the lungs
(via the pulmonary veins) into the left atrium. This oxygenated blood then passes
through the bicuspid valve into the left ventricle. It is then pumped to the aorta
under greater pressure (as explained below). This higher pressure ensures that
the oxygenated blood leaving the heart via the aorta is effectively delivered to
other parts of the body via the vascular system of blood vessels (incl. arteries,
arterioles, and capillaries).
Blood. Our blood carries oxygen to cells. It carries waste (carbon dioxide, Urea
and lactic acid - via diffusion) away from cells and carries various disease-
fighting cells such as the "white" blood cells. It is part of the body's self-repair
mechanism (blood clotting after an open wound in order to stop bleeding - using
'Platelets') and regulates our body PH. It also regulates our core body
temperature.
Blood vessels. The point of blood vessels is to carry blood throughout the body.
Arteries and veins are the largest of the blood vessels. Arteries move blood,
which contains oxygen and nutrients to muscles and organs and veins carry the
blood back to the heart.
RENAL SYSTEM
Renin-Angiotensin-Aldosterone system. When blood volume falls or blood flow to
the kidneys decreases, juxtaglomerular cells in the kidneys secrete renin into the
bloodstream. In sequence, renin and angiotensin converting enzyme (ACE) act
on their substrates to produce the active hormone angiotensin II, which raises
blood pressure in two ways. First, angiotensin II is a potent vasoconstrictor; it
raises blood pressure by increasing systemic vascular resistance. Second, it
stimulates secretion of aldosterone, which increases reabsorption of sodium ions
and water by the kidneys. The water reabsorption increases total blood volume,
which increases blood pressure.
Antidiuretic hormone. ADH is produced by the hypothalamus and released from
the posterior pituitary in response to dehydration or decreased blood volume.
Among other actions, ADH causes vasoconstriction, which increases blood
pressure.
Atrial Natriuretic Peptide. Released by cells in the atria of the heart, ANP lowers
blood pressure by causing vasodilation and by promoting the loss of salt and
water in the urine, which reduces blood volume.

TPR
Pressure towards normal
Blood pressure is generated by cardiac contraction against the vascular resistance. Having one or more of the risk factors of hypertension contributes in some changes in arteriolar bed which will then increase the systemic vascular resistance. As the systemic vascular resistance increase, the afterload also increases, therefore heart works harder. Afterload is inversely proportional to stroke volume. During a heartbeat, the heart muscle contracts. This causes the blood to be pumped out, which causes increased pressure in the arteries. There is a stronger than normal force of contraction since the filling pressures is greater and so the SV is greater. Starling’s Law states that the greater the tension or stretch the greater the contraction. Therefore wall tension is chronically increased and this results in remodeling of the ventricular wall again but this time the CXR shape is elongated and off center. This thickness is also associated with an increase in radius to keep their ratio equal. The peripheral blood vessels will return their blood flow back to normal after a sudden increase within less than a minute. There is the metabolic theory that states when the art pressure becomes too great, there is an excess flow of oxygen and nutrients which causes the blood vessels to constrict and flow to return to normal and there is the myogenic theory that states the sudden stretch of small blood vessels cause the smooth muscle of the vessel wall to contract and this reduces the blood flow. Renin will then be released by the juxtoglomerular cells in afferent arterioles of the kidney in response to SNS stimulation. The receptors that mediate this are beta receptors on cells. Renin will then increase the production of angiotensin I which will lead to Angiotensin II which is a potent vasoconstrictor which then increases total peripheral resistance. Angiotensin II will also stimulate the release of aldosterone from the medulla which will increase sodium reabsorption so less Na leaves the body and more stays in which increase ECF volume. There is also progressive increase in TPR while at the same time the CO is decreased back to normal. (Changes almost certainly caused by the long-term blood flow autoregulation mechanism). CO has risen to high level and had initiated the hypertension, the excess blood flow through the tissues than caused progressive constriction of the local arterioles, thus returning the local blood flow and the CO almost back to normal, but simultaneously causing a secondary increase in TPR. The increased TPR occurs and will lead to increase pressure towards normal.
