Essential hypertension (also called primary hypertension, or idiopathic hypertension) is a form of hypertension without an identifiable physiologic cause. [1][2] It is the most common type affecting 85% of those with high blood pressure. [3][4] The remaining 15% is accounted for by various causes of secondary hypertension. [3]
Benign hypertension or benign essential hypertension are historical terms that are considered misleading, [1] as hypertension is never benign, and consequently they have fallen out of use (see history of hypertension). The terminology persisted in the International Classification of Disease (ICD9), but is not included in the current ICD10.
Hypertensive heart disease. Hypertensive heart disease includes a number of complications of high blood pressure that affect the heart. While there are several definitions of hypertensive heart disease in the medical literature, [1][2][3] the term is most widely used in the context of the International Classification of Diseases (ICD) coding ...
The latest statistics suggest that nearly half of Americans have hypertension with a systolic pressure greater than 130 or a diastolic pressure greater than 80. This is referred to as Stage 1 ...
Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [ 11 ] High blood pressure usually does not cause symptoms itself. [ 1 ] It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral ...
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 can be classified by cause as either essential (also known as primary or idiopathic) or secondary. About 90–95% of hypertension is essential ...
Prehypertension. Prehypertension, also known as high normal blood pressure and borderline hypertensive (BH), [ 1 ] is a medical classification for cases where a person's blood pressure is elevated above optimal or normal, but not to the level considered hypertension (high blood pressure). Prehypertension is now referred to as "elevated blood ...
Diagnosis. The term hypertensive emergency is primarily used as a specific term for a hypertensive crisis with a diastolic blood pressure greater than or equal to 120 mmHg or systolic blood pressure greater than or equal to 180 mmHg. [10] Hypertensive emergency differs from hypertensive urgency in that, in the former, there is evidence of acute ...
