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 ...
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.

Hypertension in cats is indicated with a systolic blood pressure greater than 150 mmHg, with amlodipine the usual first-line treatment. A cat with a systolic blood pressure above 170 mmHg is considered hypertensive.
Orthostatic diastolic hypertension is a condition in which the diastolic BP raises to 98 mmHg or over in response to standing, [2] [3] [4] but this definition currently lacks clear medical consensus, so is subject to change. Orthostatic hypertension involving the systolic BP is known as systolic orthostatic hypertension.
Severely elevated blood pressure (equal to or greater than 180 mmHg systolic or 120 mmHg diastolic) is referred to as a hypertensive crisis (sometimes termed malignant or accelerated hypertension), due to the high risk of complications.
If the systolic blood pressure is elevated (>140) with a normal (<90) diastolic blood pressure (DBP), it is called isolated systolic hypertension. [2] Eighty percent of people with systolic hypertension are over the age of 65 years old. [3] Isolated systolic hypertension is a specific type of widened (or high) pulse pressure.
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]
Labile hypertension occurs when there are unexpected changes in blood pressure. The term can be used to describe when people have blood pressure measurements that abruptly fluctuate from being abnormally high, approximately 140/90 mm Hg or over and returns to its normal range.
