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 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 ...
The risk of stroke increases exponentially from 30 years of age, and the cause varies by age. [246] Advanced age is one of the most significant stroke risk factors. 95% of stroke occurs in people age 45 and older, and two-thirds of stroke occurs in those over the age of 65. [53] [230]

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. [19]
The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2] Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis. [5]
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.
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 ...
