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 ...

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.

Labile hypertension can be a primary risk factor that may contribute to stroke or cardiovascular disease (CVD). Prevention of life threatening complications involves lifestyle changes such as avoidance of smoking and reducing the amount of salt , caffeine and alcohol intake.
Hypertension is usually treated to achieve a blood pressure of below 140/90 mmHg to 160/100 mmHg. According to one 2003 review, reduction of the blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21% and reduce the likelihood of dementia, heart failure, and mortality from cardiovascular disease.

High levels of physical activity reduce the risk of stroke by about 26%. [107] There is a lack of high quality studies looking at promotional efforts to improve lifestyle factors. [108] Nonetheless, given the large body of circumstantial evidence, best medical management for stroke includes advice on diet, exercise, smoking and alcohol use. [109]
Commonly, ischemic heart attack and stroke are the causes that lead to death in patients with severe hypertension. It is estimated that for every 20 mm Hg systolic or 10 mm Hg diastolic increase in blood pressures above 115/75 mm Hg, the mortality rate for both ischemic heart disease, cancer and stroke doubles.
