|
A stroke is the sudden death of brain cells in a localized area due to inadequate blood flow.
|
 |
A stroke is an interruption of the blood supply to any part of the brain. A stroke is sometimes called a "brain attack." See also: Arteriovenous malformation (AVM)
|
|
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 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.

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).

|
A heart attack is the death of, or damage to, part of the heart muscle because its blood supply is severely reduced or stopped.
|
 |
A heart attack is when blood vessels that supply blood to the heart are blocked, preventing enough oxygen from getting to the heart. The heart muscle dies or becomes permanently damaged. Your doctor calls this a myocardial infarction.
