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.

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.
Chronic vasoconstriction is associated with hypertension, a major risk factor for cardiovascular diseases such as heart attack and stroke. Moreover, impaired blood flow resulting from abnormal vasoconstriction may contribute to tissue ischemia, which can be observed in conditions like Raynaud's disease.
The definition includes heart failure and other cardiac complications of hypertension when a causal relationship between the heart disease and hypertension is stated or implied on the death certificate. In 2013 hypertensive heart disease resulted in 1.07 million deaths as compared with 630,000 deaths in 1990.
A hypertensive emergency is very high blood pressure with potentially life-threatening symptoms and signs of acute damage to one or more organ systems (especially brain, eyes, heart, aorta, or kidneys). It is different from a hypertensive urgency by this additional evidence for impending irreversible hypertension-mediated organ damage (HMOD).
High blood pressure usually does not cause symptoms. [63] Long term high blood pressure, however, is a major risk factor for coronary artery disease, stroke, heart failure, peripheral vascular disease, vision loss, and chronic kidney disease. [64] [65] Lifestyle factors can increase the risk of hypertension.

This is because the condition is not yet well defined and makes it difficult for doctors to treat labile hypertension as medications are usually given for patients who have hypertension. Generally, doctors will suggest people to monitor and observe their blood pressure throughout the day, preferably for 24 hours, as commonly prescribed ...
