A diagram explaining factors affecting arterial pressure. Pathophysiology is a study which explains the function of the body as it relates to diseases and conditions. The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure.
Hypertension is the leading cause of strokes and studies show that it increases the risk of a stroke by 220% [17] [18] and stroke is the leading cause of long-term disability. [19] High blood pressure weakens arteries (small vessel disease) and causes blood vessels to be more likely to clog and/or burst.
Left ventricular hypertrophy. Hypertensive heart disease is the result of structural and functional adaptations [18] leading to left ventricular hypertrophy, [19] [20] [21] diastolic dysfunction, [18] [20] CHF (Congestive Heart Failure), abnormalities of blood flow due to atherosclerotic coronary artery disease [18] and microvascular disease, [10] [19] and cardiac arrhythmias.

Hypertension occurs in around 0.2 to 3% of newborns; however, blood pressure is not measured routinely in healthy newborns. [42] Hypertension is more common in high risk newborns. A variety of factors, such as gestational age, postconceptional age, and birth weight need to be taken into account when deciding if blood pressure is normal in a ...
Without proper treatment, hypertension can lead to: Atherosclerosis (a buildup of plaque in your arteries) Stroke. Cardiovascular disease. Heart failure. Heart attack. Eye damage. Kidney failure ...
The pathophysiology of hypertension is that of a chronic disease characterized by elevation of blood pressure. Hypertension can be classified by cause as either essential (also known as primary or idiopathic) or secondary. About 90–95% of hypertension is essential hypertension. [23] [24] [25] [26]
Hypertension in AD may result in mild symptoms, such as sweating above the lesion level, goosebumps, blurred vision, or headache. [7] Severe symptoms may result in life-threatening complications including seizure, intracranial bleeds (stroke), myocardial infarction, and retinal detachment. [8] Both noxious and non-noxious stimuli can trigger AD.
Hypertension is a strong risk factor. So-called deep-perforating arteries – relatively small arteries branching off of relatively large arteries (most commonly the lenticulostriate arteries from the middle cerebral artery) – are especially prone. [3] Uncontrolled hypertension and diabetes are both risk factors for this condition. [citation ...
