Heart disease is any disorder that affects the heart's ability to function normally. Various forms of heart disease include: Alcoholic cardiomyopathy; Aortic regurgitation; Aortic stenosis; Arrhythmias; Cardiogenic shock; Congenital heart disease; Coronary artery disease (CAD)Dilated cardiomyopathy; Endocarditis; Heart attack (myocardial infarction; Heart failure; Heart tumor; Hypertrophic cardiomyopathy; Idiopathic cardiomyopathy; Ischemic cardiomyopathy; Acute mitral regurgitation; Chronic mitral regurgitation; Mitral stenosis; Mitral valve prolapse; Peripartum cardiomyopathy; Pulmonary stenosis; Stable angina; Unstable angina; Tricuspid regurgitation.

The heart, which is about the size of a human fist, is the body ' s largest, strongest, and most important muscle. The heart continuously pumps blood through the body, helps regulate and prolong health, and controls the flow (circulation) of blood to the lungs, organs, muscles, and tissues in the body.

Hypertension is the term doctors use for high blood pressure. Blood pressure readings are measured in millimeters of mercury (mmHg) and usually given as 2 numbers. For example, 140 over 90 (written as 140/90. The top number is your systolic pressure, the pressure created when your heart beats. It is considered high if it is consistently over 140; The bottom number is your diastolic pressure, the pressure inside blood vessels when the heart is at rest. It is considered high if it is consistently over 90. Either or both of these numbers may be too high. Pre-hypertension is when your systolic blood pressure is between 120 and 139 or your diastolic blood pressure is between 80 and 89 on multiple readings. If you have pre-hypertension, you are more likely to develop high blood pressure at some point. See also: Blood pressure

|
In populations, blood pressures fit a normal distribution, but the attendant risks of heart disease and stroke increase curvilinearly with increasing levels of blood pressure, without any obvious breakpoint ( Fig. 63-1 ). Thus, the separation of normal from high blood pressure is arbitrary, and the definition of hypertension has been a moving target.

Blood pressure is the force with which blood pushes against the artery walls as it travels through the body. Like air in a balloon, blood fills arteries to a certain capacity- and just as too much air pressure can cause damage to a balloon, too much blood pressure can harm healthy arteries.

Also known as high blood pressure, a condition in which too much force is exerted by the blood as it travels through the body ' s arteries. There are two types of hypertension: primary and secondary.
|
|
Hypertension is an independent risk factor for coronary artery disease (CAD) and stroke, leading causes of morbidity and mortality in North America. Concern has been raised that there is inadequate outpatient detection, evaluation, and treatment of hypertension, and that this is resulting in increased hospital admissions with complications of untreated hypertension: heart failure, and end-stage renal disease .

Hypertension is the medical term for high blood pressure. Blood pressure is the force of blood pushing against the walls of arteries as it flows through them.
|
|
The National High Blood Pressure Education Program (NHBPEP) was established in 1972 by the National Institute of Health to translate research results on the health hazards of high blood pressure into clinical and public health practice. Before 1900, high blood pressure, or hypertension, was not generally recognized as a health problem.

Unconsciousness is when a person is unable to respond to people and activities. Often, this is called a coma or being in a comatose state. Other changes in awareness can occur without becoming unconscious. Medically, these are called "altered mental status" or "changed mental status." They include sudden confusion, disorientation, or stupor. Unconsciousness and any other SUDDEN change in mental status must be treated as a medical emergency. If someone is awake but less alert than usual, ask a few simple questions, such as: What is your name; What is the date; How old are you. Wrong answers or an inability to answer suggest a change in mental status.

Problems involving disruption in sleep pattern or inability to sleep. Sleep is a period of decreased activity and muscle relaxation, characterized by patterns of deep sleep (where brain waves are slower, called non-rapid eye movement sleep) alternating with dreaming sleep, known as rapid eye movement (REM) sleep.

Sleep disorders are a group of syndromes characterized by disturbance in the individual ' s amount of sleep, quality or timing of sleep, or in behaviors or physiological conditions associated with sleep. Although sleep is a basic behavior in animals as well as humans, researchers still do not completely understand all of its functions in maintaining health.

|
Circadian rhythm sleep disorder is a persistent or recurring pattern of sleep disruption resulting either from an altered sleep-wake schedule or an inequality between a person ' s natural sleep-wake cycle and the sleep-related demands placed on him or her. The term circadian rhythm refers to a person ' s internal sleep and wake-related rhythms that occur throughout a 24-hour period.
|
|
Sleep disorders are chronic disturbances in the quantity or quality of sleep that interfere with a person's ability to function normally. An estimated 15% of Americans have chronic sleep problems, while about 10% have occasional trouble sleeping.

A stroke is an interruption of the blood supply to any part of the brain. A stroke is sometimes called a "brain attack."
|
|
The following Clinical Topic Tour provides an overview of stroke and was adapted from materials published by the National Institute of Neurological Disorders and Stroke and the Centers for Disease Control and Prevention.

|
A stroke is the sudden death of brain cells in a localized area due to inadequate blood flow. A stroke occurs when blood flow is interrupted to part of the brain.
|
|
A stroke is an interruption of blood circulation to the brain causing a neurologic deficit reflecting the area of the brain affected. Stroke can be ischemic or hemorrhagic. 1 Ischemic stroke is most prevalent.
|
|
Stroke is an increasing public health concern throughout the world as the leading cause of long-term disability. There is estimated to be over 3.5 million survivors of stroke in the United States.

A stroke is the sudden death of brain cells in a localized area due to inadequate blood flow. A stroke occurs when blood flow is interrupted to part of the brain.
|
|
There are various clinical and pathological subtypes of stroke, and identification of the subtype is necessary for correct management. Investigations Imaging Brain imaging should be performed within the first 48 hours of the onset of stroke (see below), to determine whether the stroke is haemorrhagic or ischaemic and to exclude other causes (e.g. tumour).
|
|
Stroke, or cerebrovascular accident (CVA), is the third leading cause of death (after heart disease and cancer) in the United States and the industrialized countries of the world. The term " stroke, " which comes from subjects being suddenly " struck down " with neurological deficits, is commonly used by both professional and lay groups.
|
|
|
Cerebrovascular accident (CVA) is the medical term for what is commonly termed a stroke. It refers to the injury to the brain that occurs when flow of blood to brain tissue is interrupted by a clogged or ruptured artery, causing brain tissue to die because of lack of nutrients and oxygen.
|
|
|
A stroke, also called a cerebral infarction, is a life-threatening condition marked by a sudden disruption in the blood supply to the brain. A disruption in the blood supply to the brain starves the brain of oxygen-rich blood and causes the nerve cells in that area to become damaged and die within minutes.
|
|
A stroke, also called a cerebral vascular accident (CVA), is the sudden death of cells in a specific area of the brain due to inadequate blood flow. A stroke occurs when blood flow is interrupted to a part of the brain, either when an artery bursts or becomes closed when a blood clot lodges in it.
|
|
|
Stroke is the common name for the injury to the brain that occurs when the flow of blood to brain tissue is interrupted by a clogged or burst artery. Arterial blood carries oxygen and nutrition to the cells of the body.
