Orthostatic hypotension may cause accidental falls. [11] It is also linked to an increased risk of cardiovascular disease, heart failure, and stroke. [42] [27] Also, observational data suggest that orthostatic hypotension in middle age increases the risk of eventual dementia and reduced cognitive function. [43]
There are three broad categories of causes: heart or blood vessel related; reflex, also known as neurally mediated; and orthostatic hypotension. [1] Issues with the heart and blood vessels are the cause in about 10% and typically the most serious while neurally mediated is the most common. [1] There also seems to be a genetic component to syncope.
Dysautonomia, autonomic failure, or autonomic dysfunction is a condition in which the autonomic nervous system (ANS) does not work properly. This condition may affect the functioning of the heart, bladder, intestines, sweat glands, pupils, and blood vessels. Dysautonomia has many causes, not all of which may be classified as neuropathic.

Orthostatic syncope refers to syncope resulting from a postural decrease in blood pressure, termed orthostatic hypotension. [1]Orthostatic hypotension occurs when there is a persistent reduction in blood pressure of at least 20mmHg systolic or 10mmHg diastolic within three minutes of standing or being upright to 60 degrees on the head-up tilt table.
The majority of symptoms that patients with PAF exhibit are associated with neurogenic orthostatic hypotension, or orthostatic hypotension brought on by severe sympathetic failure. Within three minutes of standing up straight, orthostatic hypotension is defined as a drop in systolic blood pressure of at least 20 mm Hg or a drop in diastolic ...
Symptoms commonly documented in patients history, classified according to cause: [2] [5] [6] [8] [9] Neurological - Dizziness, near syncope, and confusion. Heart failure - Dyspnea, orthopnea, paroxysmal nocturnal dyspnea, and edema. Hypotension - Seizure, mental status change, diaphoresis, and signs of orthostatic hypotension and shock.
Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
This is a shortened version of the seventh chapter of the ICD-9: Diseases of the Circulatory System. It covers ICD codes 259 to 282. The full chapter can be found on pages 215 to 258 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
