Patients with paroxysmal hypertension who test negative for pheochromocytoma are said to be suffering from a clinical entity called "pseudopheochromocytoma." This disorder is due to episodic dopamine discharge and has been observed predominantly in hypertensive women whose presentation mimicked pheochromocytoma , but with subsequent testing ...
Renovascular hypertension is caused by diminished blood flow to one or both kidneys. As a result, the kidneys release hormones that cause the body to retain sodium and water, leading to elevated blood pressure. There are many causes of decreased blood flow to the kidneys. These include: [5] Atherosclerotic renal artery stenosis; Fibromuscular ...
Automated blood pressure measurements over 15 to 20 minutes in a quiet part of the office or clinic can reduce (but not eliminate) incorrect blood pressure measures. [8] People with white coat hypertension do not exhibit the signs indicative of trepidation and their increased blood pressure is often not accompanied by tachycardia. [9]
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 140/90mm Hg or over and returns to its normal range.
A minimum systolic value can be roughly estimated by palpation, most often used in emergency situations, but should be used with caution. [10] It has been estimated that, using 50% percentiles, carotid, femoral and radial pulses are present in patients with a systolic blood pressure > 70 mmHg, carotid and femoral pulses alone in patients with systolic blood pressure of > 50 mmHg, and only a ...
Blood pressure targets [7] <1 hr 25% reduction in the mean arterial pressure, diastolic blood pressure above 100 2-6 hr Systolic BP < 160 mmHg or Diastolic BP <110 mmHg 6-24 hr monitor BP targets, ensure non-rapid drop in BPs below 160 SBP or 100 DBP 1-2 d if no end-organ damage, monitor out-patient and JNC8 Guidelines for maintaining BP control
Secondary hypertension (or, less commonly, inessential hypertension) is a type of hypertension which has a specific and identifiable underlying primary cause. It is much less common than essential hypertension, affecting only 5-10% of hypertensive patients.
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 categories.
