[9] [10] Of all people with hypertension, about 46% do not have a diagnosis of hypertension and are unaware that they have the condition. [13] [9] In 1975, almost 600 million people had a diagnosis of hypertension, a number which increased to 1.13 billion by 2015 mostly due to risk factors for hypertension increasing in low- and middle-income ...
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. [2]
Although severe hypertension is more common in the elderly, it may occur in children (though very rarely), likely due to metabolic or hormonal dysfunction. In 2014, a systematic review identified women as having slightly higher increased risks of developing hypertensive crises than do men.
In studies, white coat hypertension can be defined as the presence of a defined hypertensive average blood pressure in a clinic setting, although it isn't present when the patient is at home. [ 5 ] Diagnosis is made difficult as a result of the unreliable measures taken from the conventional methods of detection.
In addition, hypertension precedes heart failure in 90% of cases, [7] and the majority of heart failure in the elderly may be attributable to hypertension. [17] Hypertensive heart disease was estimated to be responsible for 1.0 million deaths worldwide in 2004 (or approximately 1.7% of all deaths globally), and was ranked 13th in the leading ...
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]
The term can be used to describe when people have blood pressure measurements that abruptly fluctuate from being abnormally high, approximately 140/90mm Hg or over and returns to its normal range. [1] Patients who have labile hypertension may have higher cardiac output and lower total peripheral resistance than others. [2]
Primary hypertension, also known as essential hypertension, is the result of a consistent elevation of the force of blood being pumped throughout the body, whereas secondary hypertension is the result of high blood pressure due to another medical condition.> Diseases that can cause secondary hypertension include diabetic nephropathy, glomerular disease, polycystic kidney disease, cushing ...
