Overview

The most common cause of hypertension in 90% of cases is essential hypertension where no clear identifying underlying cause can be identified, and the pathophysiology of which is incompletely understood. There are many secondary causes of hypertension.

The Most Common Cause

The most common cause of hypertension is essential hypertension which accounts for about 90% of cases of elevated blood pressure.

Common Causes of Secondary Hypertension

In only a small minority of patients with elevated arterial pressure can a specific cause be identified. An underlying endocrine or renal defect is most often identified, that if corrected, may restore the blood pressure back to normal.

When to Suspect Secondary Hypertension

A secondary cause of hypertension should be suspected if the patient has resistant hypertension. The AHA Scientific Statement 2008 defines resistant hypertension as a blood pressure which remains above the goal of 140/90 mm Hg despite concurrent use of 3 antihypertensive medications of different classes at optimal doses, including a diuretic..

Other features that suggest secondary hypertension include:

• Recent onset of hypertension
• Unprovoked hypokalemia or an inappropriately low potassium (e.g. a "normal K" on an ACE inhibitor plus a K sparing diuretic)
• Presence of peripheral arterial disease
• Increase in creatine with ACE inhibition
• Loss of control of previously controlled hypertension

Before evaluating the patient for secondary hypertension, non-compliance with antihypertensives should be ruled out. Given its prevalence in the Unites States population, sleep apnea should also be ruled out early in the evaluation.

Common Causes of Secondary Hypertension

Common causes of secondary hypertension include:

• Anxiety: Hypertension is often confused with mental tension, stress and anxiety. While chronic anxiety is associated with poor outcomes in people with hypertension, it alone probably does not cause it.
• Arteriosclerosis
• Chronic kidney disease. This includes diseases such as polycystic kidney disease or chronic glomerulonephritis.
• Congenital adrenal hyperplasia
• Cushing's syndrome due to an excessive secretion of glucocorticoids which in turn causes the hypertension
• Drugs:

• Nasal decongestants with adrenergic effects
• NSAIDs
• Oral contraceptives
• Steroids

• Fever
• Hyperaldosteronism (Conn's syndrome): Hypertension is a feature of a variety of adrenal cortical abnormalities. In primary aldosteronism there is a clear relationship between the aldosterone-induced sodium retention and the hypertension. Suspect hyperaldosteronism if the patient has an unusual sensitivity to a diuretic in causing hypokalemia, if there is frequent hypokalemia, and if there is a normal potassium in the setting of ACE inhibition with a potassium spairing diuretic. The plasma renin activity is suppressed and there is elevated aldosterone on adrenal vein sampling.

• Idiopathic hyperaldosteronism
• Liddle's syndrome (also called pseudoaldosteronism)
• Glucocorticoid remediable aldosteronism

• Hyperthyroidism
• Hypothyroidism
• Increased salt intake
• Metabolic syndrome
• Non-compliance with antihypertensives
• Obesity
• Obstructive sleep apnea can cause a rise in catecholamines
• Perioperative hypertension: this is the development of hypertension just before, during or after surgery. It may occur before surgery during the induction of anesthesia; intraoperatively e.g. by pain-induced sympathetic nervous system stimulation; in the early postanesthesia period, e.g. by pain-induced sympathetic stimulation, hypothermia, hypoxia, or hypervolemia from excessive intraoperative fluid therapy; and in the 24 to 48 hours after the postoperative period as fluid is mobilized from the extravascular space. In addition, hypertension may develop perioperatively because of discontinuation of long-term antihypertensive medication.
• Pheochromocytoma: Caused by an excessive secretion of norepinephrine and epinephrine which promotes vasoconstriction. Consider this diagnosis in the patient who has headaches, diaphoresis, palpitations, orthostatic hypotension, hypertension with anesthesia induction and those patients with a dilated cardiomyopathy (which a pheochromocytoma can cause) who still have an elevated blood pressure despite a loss in cardiac output. This diagnosis is confirmed by demonstrating increased urinary excretion of epinephrine and norepinephrine and/or their metabolites (vanillylmandelic acid).
• Pregnancy causing gestational hypertension
• Renovascular hypertension: Due to fibromuscular dysplasia and renal artery stenosis. In both conditions, increased blood pressure occurs due to narrowing of arteries supplying to the kidney. Decreased perfusion of renal tissue due to stenosis of a main or branch renal artery activates the renin-angiotensin system.

Tests to Assess for Renovascular Hypertension

• Renal Ultrasound: Look for a difference in the size of kidneys
• CT: Although there is a dye load, there is no Gadollinium which can be toxic with an MRI, the images are better than MRI
• Indications for Arteriographic Imaging to Rule Out Renovascular Hypertension

Class I

• Hypertension in a patient < 30 yrs old
• Severe increase in blood pressure in a patient > 55 yrs old
• Accelerated increase in BP
• Resistant increase in BP
• Complicated malignant increase in BP
• Reduction in GFR or rise in Cr with RAS blockade
• > 1.5 cm difference in renal size on ultrasound
• Flash pulmonary edema

Class IIa

• Unexplained renal failure

Class IIb

• Multivessel CAD or PAD
• Unexplained CHF or refractory angina

• Scleroderma
• Stress
• White coat hypertension

Common causes of Resistant hypertension

• Improper blood pressure measurement

• Volume overload
  • Excess sodium intake
  • Volume retention from kidney disease
  • Inadequate diuretic therapy

• Drug-induced or other causes
  • Non-adherence
  • Inadequate doses
  • Inappropriate combinations
  • NSAIDs, COX inhibitors
  • Cocaine, amphetamines, other illicit drugs
  • Sympathomimetics (decongestants, anorectics)
  • Oral contraceptive therapy
  • Adrenal steroid hormones
  • Cyclosporine, tacrolimus
  • Eruthropoetin
  • Licorice (including some chewing tobacco)
  • Selected over the counter dietary supplements (like ephedra, ma huang, bitter orange)

Less Common Cuases

• Acromegaly
• Coarctation of the aorta
• Hyperparathyroidism
• Liquorice (black, not red). Drives up cortisol causing a Cushing-like syndrome.
• Neurofibromatosis
