It is uncertain as to why the initial tear (rent) occurs in the intima layer
of the aortic wall. Aortic dissection tends to occur most commonly in men
between the ages of 50 and 70.
High blood pressure: Most cases (over 70%) are associated with
high blood
pressure (hypertension). The aorta has to withstand significant pressure
changes with each heart beat, and it may be that over time with hypertension, a
weakening of an area of the intima will occur.
Pregnancy:Pregnancy is also an associated risk factor, especially in the third
trimester and early in the post-partum period.
Trauma: Blunt trauma is known to cause aortic dissection, often seen after car wrecks
in which the patient's chest hits the steering wheel.
Surgical complications: Aortic dissection can be a complication of medical
operations including coronary artery bypass grafting and aortic and mitral valve
repairs. It can also be a complication of heart catheterization.
What are the signs and symptoms of aortic dissection?
Pain is the most common symptom of aortic dissection and is often described
as tearing or ripping. The pain usually begins suddenly and is centered in the
chest, radiating directly into the upper back.
Other symptoms may be related to the location of the dissection within the
aorta and whether it affects some of the branch arteries and occludes their
blood supply. For example, if an artery that supplies blood to the brain is
involved, there may be signs of stroke, or if the dissection affects the
anterior spinal artery and blood supply to the spinal cord, the patient may
present with paraplegia.
The coronary arteries that supply blood to the heart begin at the origin of the
aorta at the aortic valve. If the coronary arteries are involved, the aortic
dissection may cause a heart attack (myocardial infarction).
The patient may present with congestive heart failure with fluid building
up in the lungs. If the aortic dissection involves the aortic valve and causes
it to fail, blood flows back into the heart with each beat and causes blood flow
to back-up into the lungs
There may be significant abdominal or flank (the side of the body between
the ribs and hip) pain.
The pain of aortic dissection can be confused with that of heart attack,
but can sometimes be distinguished because of its sudden onset and normal
electrocardiogram.
The patient may also have a sense of impending doom.
Low blood pressure, also referred to as hypotension, is blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through the arteries and veins. Some of the symptoms of low blood pressure include light-headedness, dizziness, or even fainting if not enough blood is getting to the brain. Diseases and medications can also cause low blood pressure. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys; the organs do not function normally and may be permanently damaged.
Congestive heart failure (CHF) is a condition in which the heart's function as a pump is inadequate to meet the body's needs. A poor blood supply resulting from congestive heart failure may cause the body's organ systems to fail, leading to a weakened heart muscle and fluid accumulation in the lungs and body tissue. There are many diseases that can impair pumping efficiency and symptoms of congestive heart failure including fatigue, diminished exercise capacity, shortness of breath, and swelling. Treatments include lifestyle modifications, medications, heart transplant, and therapy.
High blood pressure, also known as hypertension, is a repeatedly
elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above
140 with a diastolic pressure above 90. There are two causes of high blood pressure, primary and secondary. Primary high blood pressure is much more common that secondary and its basic causes or underlying defects are not always known. It is known that a diet high in salt increases the risk for high blood pressure, as well as high cholesterol. Genetic factors are also a primary cause. Secondary high blood pressure is generally caused by another condition such as renal hypertension, tumors, and other conditions. Treatment for high blood pressure is generally lifestyle changes and if necessary, diet.
A stroke results from impaired oxygen delivery to brain cells via the bloodstream. A stroke is also referred to as a CVA, or cerebrovascular incident. Symptoms of stroke include: sudden numbness or weakness of the face, arm or leg. Sudden confusion, trouble speaking or understanding. Sudden trouble seeing in one or both eyes, sudden trouble walking, dizziness, or loss of balance, and/or sudden severe headache with no known cause. A TIA, or transient ischemic attack is a short-lived temporary impairment of the brain caused by loss of blood supply. Stroke is a medical emergency.
Sexually transmitted diseases, or STDs,
are infections that are transmitted during any type of sexual exposure,
including intercourse (vaginal or anal), oral sex, and the sharing of sexual
devices, such as vibrators. Women can contract all of the STDs, but may have no symptoms, or have different symptoms than men do.
Heart attack happens when a blood clot completely obstructs a coronary
artery supplying blood to the heart muscle. A heart attack can cause chest pain, heart failure, and electrical
instability of the heart.
Chest pain is a common complaint by a patient in the ER. Causes of chest pain include broken or bruised ribs, pleurisy, pneumothorax, shingles, pneumonia, pulmonary embolism, angina, heart attack, costochondritis, pericarditis, aorta or aortic dissection, and reflux esophagitis. Diagnosis and treatment of chest pain depends upon the cause and clinical presentation of the patient's chest pain.
Sexually transmitted diseases, or STDs, are infections that are transmitted during any
type of sexual exposure, including intercourse (vaginal or anal), oral sex, and
the sharing of sexual devices, such as vibrators. Although treatment exists for many STDs, others currently are
usually incurable, such as those caused by HIV, HPV, hepatitis B and C, and HHV-8.
Marfan syndrome is hereditary condition affecting connective tissue. A person with Marfan syndrome may exhibit the following symptoms and characteristics: dislocation of one or both lenses of the eye; a protruding or indented breastbone; scoliosis; flat feet; aortic dilatation; dural ectasia; stretch marks; hernia; and lung collapse. Though there is no cure for Marfan syndrome, there are treatments that can minimize and sometimes prevent some complications.
Drug addiction is a chronic disease that causes drug-seeking behavior and drug use despite negative consequences to the user and those around him. Though the initial decision to use drugs is voluntary, changes in the brain caused by repeated drug abuse can affect a person's self-control and ability to make the right decisions and increase the urge to take drugs. Drug abuse and addiction are preventable.
Heart disease (coronary artery disease) is caused by a buildup of cholesterol deposits in the coronary arteries. Risk factors for heart disease include smoking, high blood pressure, heredity, diabetes, peripheral artery disease, and obesity. Symptoms include chest pain and shortness of breath. There are a variety of tests used to diagnose coronary artery disease. Treatment includes life-style changes, medications, procedures, or surgery.
Heart valve disease occurs when the heart valves do not work the way they should. Symptoms of valve disease include shortness of breath, weakness or dizziness, discomfort in your chest, palpitations, swelling of your ankles, feet or abdomen, and rapid weight gain.
A heart murmur is the sound generated when blood flow within the heart is not smooth. Causes of heart murmurs can be functional, congenital, or caused heart valve conditions. Symptoms of a heart murmur may be none, or may include chest pain, shortness of breath, and arm, leg, and ankle swelling. Treatment of a heart murmur depends on the cause.
Turner syndrome is an inherited chromosomal condition affecting women. Women with Turner syndrome do not have ovarian function, and features of the syndrome include webbed neck, lymphedema of the hands and feet, heart defects, kidney problems, and skeletal abnormalities. The X chromosome is related to Turner syndrome. Treatment focuses on the symptoms of the syndrome.
Ehlers-Danlos syndromes are genetic disorders that include symptoms such as loose joints, tissue weakness, easy bruising, and skin that stretches easily. There are seven types of Ehlers-Danlos syndromes: Classical type, Hypermobility type, Vascular type, Kyphoscoliosis type, Arthrochalsia type, Dermatosparaxis type, and Tenascin-X Deficient type. Treatment for Ehlers-Danlos syndromes depends on which symptoms are present.
Syphilis, a sexually transmitted disease, is caused by a microscopic, wormlike bacterial organism called a spirochete. There are three stages of syphilis. The first involves the formation of the chancre. The second stage often includes hair loss, a sore throat, white patches in the nose, mouth, and vagina, fever, headaches, and a skin rash. The third stage can cause extensive damage to the internal organs and the brain, and can lead to death. Though early infection often resolves on its own, treatment usually varies based on the stage of the infection at the time of diagnosis.
Heart failure is caused by many conditions including coronary artery disease, heart attack, cardiomyopathy, and conditions that overwork the heart. Symptoms of heart failure include congested lungs, fluid and water retention, dizziness, fatigue and weakness, and rapid or irregular heartbeats.
The heart is a very important organ in the body. It is responsible for continuously pumping oxygen and nutrient-rich blood throughout your body to sustain life. It is a fist-sized muscle that beats (expands and contracts) 100,000 times per day, pumping a total of five or six quarts of blood each minute, or about 2,000 gallons per day.
