|
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.

|
|
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).

Hypertension is the term used to describe high blood pressure.Blood pressure readings are measured in millimeters of mercury(mmHg) and usually given as two numbers. For example, 120 over 80(written as 120/80 mmHg).The top number is your systolic p...
|
|
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.
|
 |
The lower number is the diastolic pressure, which is the pressure when the heart is filling or relaxing before the next beat. Normal blood pressure for an adult is 120/70(on average), but normal for an individual varies with the height, weight, fi...

The following Clinical Topic Tour provides an overview of hypertension (HTN) and was adapted from materials published by the NHLBI.
|
 |
Primary, or essential, hypertension is caused by external factors; secondary hypertension is related to an underlying disorder, such as a congenital heart defect or kidney disease. Factors that increase the risk of high blood pressure include age(...
|
|
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...
