Overview

Secondary hypertension is only responsible for 5% of cases of chronic hypertension whereas primary hypertension (also known as essential hypertension where no identifiable cause is identified) is responsible for 95% of cases.^[1] Common causes of secondary hypertension include obstructive sleep apnea, hyperaldosteronism, kidney diseases, excess catecholamines, coarctation of the arota, cushing syndrome among other diseases.

Chronic hypertension

Primary hypertension
(also known as essential hypertension)
(95% of the cases)

Secondary hypertension

(5% of the cases)

Primary Hypertension

When a full evaluation yields no clear etiology for the elevated blood pressure, the latter is identified as primary hypertension. Primary or essential hypertension is considered a chronic disease requiring lifelong treatment and follow-up. If an underlying disease is identifiable as the cause, secondary hypertension is diagnosed. Secondary hypertension is a potentially curable condition in most cases.^[2] In comparison, the prevalence of primary hypertension is significantly higher than secondary hypertension, where only 5-10% of patients have a secondary etiology^[1] Classically, the common age range for the presentation of primary hypertension is 30 to 55 years^[3], but age alone should never warrant a diagnosis of primary hypertension without a proper work-up.

Secondary Hypertension

When to Suspect Secondary Hypertension

It is not cost effective to evaluate all hypertensive patients for secondary hypertension. ^[2] There are certain clinical scenarios, though, that should prompt further evaluation.

Early Onset Hypertension Under Age 30

Primary hypertension generally first occurs between 30 and 55 years. Onset of hypertension before puberty and before age 30 in the absence of risk factors should raise suspicion for secondary hypertension.

Abrupt Onset of Hypertension in A Normotensive Patient

Rapidly Progressive Hypertension or a Hypertensive Emergency or Urgency

Refractory Hypertension

Evaluation of Secondary Hypertension

Evaluation of secondary hypertension

Investigation should be limited for patients with clues suggestive of potentially correctable causes.

❑ Presence of clues for renovascular hypertension (most common potentially correctable cause)?^[4]^[5]

❑ Onset of hypertension before the age of 30 years

❑ Onset of severe hypertension (SBP ≥180 mm Hg and/or DBP ≥120 mm Hg) after the age of 55 years

❑ New azotemia or worsening renal function after administration of an ACE inhibitor or ARB agent

❑ Unexplained atrophic kidney or size discrepancy between kidneys of greater than 1.5 cm

❑ Sudden, unexplained pulmonary edema

❑ Accelerated hypertension (sudden and persistent worsening of previously controlled hypertension)

❑ Resistant hypertension (failure to achieve goal blood pressure in patients who are adhering to full doses of an appropriate 3-drug regimen that includes a diuretic)

❑ Malignant hypertension (hypertension with coexistent evidence of acute end-organ damage, i.e., acute renal failure, acutely decompensated congestive heart failure, new visual or neurological disturbance, and/or advanced [grade III to IV] retinopathy)

❑ Unexplained renal failure in the absence of proteinuria or an abnormal urine sediment

❑ Multivessel coronary artery disease

❑ Unexplained congestive heart failure

❑ Refractory angina

YES

NO

❑ Perform noninvasive diagnostic studies

❑ Duplex ultrasonography

❑ Gadolinium-enhanced magnetic resonance angiography

❑ Computed tomographic angiography (in individuals with normal renal function)

❑ Consider catheter angiography when noninvasive studies are inconclusive

Look for findings suggestive of other identifiable causes

❑ Pheochromocytoma

❑ Paroxysmal pounding headache

❑ Palpitations

❑ Profound perspiration

❑ Pallor

❑ Hand tremor

❑ Hyperaldosteronism

❑ Unexplained hypokalemia with urinary potassium wasting

❑ Obstructive sleep apnea

❑ Daytime somnolence

❑ Snoring

❑ Obesity

❑ Hyperparathyroidism

❑ Hypercalcemia

❑ Hypothyroidism

❑ Elevated TSH

❑ Puffy face

❑ Aortic coarctation

❑ Diminished or delayed femoral pulses and low or unobtainable blood pressures in the legs

Common Causes of Secondary Hypertension

Common causes of secondary hypertension are often memorized by the mnemonic ABCDE:

Letter	Causes of Secondary Hypertension
A	Accuracy, Apnea, Aldosteronism
B	Bruit, Bad Kidneys
C	Catecholamines, Coarctation, Cushing’s Syndrome
D	Drugs, Diet
E	Erythropoitin, Endocrine Disorders

Accuracy

An accurate assessment and re-assessment of blood pressures is an essential first step when a patient presents with high blood pressure. The accuracy of home BP measurements should be confirmed by calibrating the patient's measurement technique with that obtained in the doctor's office.

Apnea

Obstructive sleep apnea (OSA) is a respiratory disease characterized by repetitive narrowing or collapse of the upper airway during sleep^[6] leading to apnea, hypopnea, and a nocturnal decrease in oxygen tension.^[7] Symptoms and signs that might suggest OSA include daytime somnolence, obesity, snoring, and morning headache.^[8] Patients with sleep apnea also tend to have drug resistant hypertension and may retain sodium. Diagnosis is made by polysomnography. Treatment relies on maintaining airway patency at night and includes, among others, the use of continuous positive airway pressure (CPAP).

Aldosterone

Primary (hyporeninemic) and secondary (hyperreninemic) hyperaldosteronism result in excess sodium and water retention with slight hypernatremia along with excretion of potassium resulting in hypokalemia in one half of patients.^[9] Common symptoms of hyperaldosteronism include drug resistant hypertension, fatigue, headache, intermittent paralysis, muscle weakness, and numbness. The most common cause of primary hyperaldosteronism is an aldosterone-producing adenoma (an "aldosteronoma"), i.e. Conn’s Syndrome. Secondary hyperaldosteronism is due to an overactive RAAS, as seen in renin-secreting tumors, renal artery stenosis, pheochromocytoma, and other syndromes. The diagnosis is made by measuring the ratio of plasma aldosterone to plasma renin activity.^[10] It is elevated in primary hyperaldosteronism and decreased/normal with elevated renin in secondary hyperaldosteronism. It should be noted that obesity can also cause aldosterone levels to be elevated. Treatment depends upon the underlying etiology: surgery to resect an adenoma causing primary hyperaldosteronism and spironolactone, an aldosterone antagonist to treat secondary hyperaldosteronism.

Bruit

Renovascular hypertension is due to decreased blood supply to the kidneys secondary to renal artery stenosis and it is the most common correctable cause of secondary hypertension. Atherosclerosis of the renal artery (renal artery stenosis) in older patients above 50 years of age^[11] and fibromuscular dysplasia in younger patients are the most common etiologies.

According to the 2013 ACC/AHA Guidelines for the Management of PAD^[12], diagnostic work-up for renal artery stenosis is indicated in the following conditions:

Class I Recommendations^[12]

Hypertension of any stage before the age of 30
Stage II hypertension (severe hypertension systolic blood pressure > 180 mm Hg or diastolic blood pressure > 120 mm Hg) in patients older than 55 years. If only mild hypertension is present, then renal artery stenosis is the underlying cause in only 1% of patients ^[13], but if the blood pressure is markedly elevated, then the risk of renal artery stenosis goes up 10 to 50 fold.
Accelerated condition of previously controlled hypertension
Resistant hypertension
Malignant hypertension
New azotemia (50% rise in creatinine that is sustained) within one week after administration of an Angiotensin Converting Enzyme (ACE)inhibitor or ARB
Unexplained atrophic kidney or asymmetric kidneys that differ by > 1.5 cm. If the kidney is < 9 cm in size, there is a 75% chance that renal artery stenosis is present.
Severe hypertension, impaired renal function, and recurrent flash pulmonary edema

Class IIa Recommendations^[12]

Unexplained renal failure including patients starting renal replacement therapy

Class IIb Recommendations^[12]

Presence of multi vessel CAD and no clinical clues of ARAS or PAD
Unexplained CHF or refractory angina

Other Indications

Severe hypertension in the presence of polyvascular disease (coronary artery disease or peripheral arterial disease)
A unilateral systolic-diastolic abdominal bruit. Although a bruit is infrequent in documented renal artery stenosis (the sensitivity is only 40% percent) if it is auscultated, it is associated with a very high specificity of 99%.^[14]
The association of race with renal artery stenosis is not clear. Reports that it is observed more often in white patients may be due to reporting bias.^[15]

Definitive diagnosis is made by magnetic resonance angiography (MRA) and renal arteriography.^[16] Other diagnostic methods include duplex ultrasound scanning^[17], and captopril-augmented radio-isotopic renogram^[18]. Treatment is based upon the underlying etiology.

Bad Kidney (Chronic Renal Failure)

Renal parenchymal disease blunts the kidney’s physiological ability to maintain appropriate blood pressure. Notably, hypertension is both a cause and a consequence of renal parenchymal disease; the two are closely associated and may potentiate each other.^[19] The diagnosis is made by demonstration of a decreased GFR. The mechanisms by which renal parenchymal disease leads to the development of hypertension are numerous and include activation of the local RAAS, release of vasoconstrictor cytokines, and inappropriate natriuresis for any given blood pressure.

Catecholamines

Catecholamine excess occurs in several non-disease states, such as acute stress, the administration of medications with sympathomimetic activity, and illicit drug use such as cocaine and these conditions can be ruled out by thorough history taking. Pheochromocytoma, a tumor of the adrenal gland leading to excess secretion of epinephrine, should be considered in young patients with the triad of intermittent hypertensive episodes causing headache, sweating, and tachycardia. However, pheochromocytoma in older adults or a presentation with sustained hypertension is not uncommon. Diagnostic studies to evaluate pheochromocytoma include measurement of plasma free metanephrines and urinary fractionated metanephrines. The diagnostic value of plasma and urinary catecholamines is of limited value given the very short half-life of catecholamines. Treatment is usually by surgical resection of the secreting tumor with appropriate adrenergic blockade.^[20]

Coarctation

Coarctation of the aorta is a congenital heart defect, caused by a narrowing in a segment of the ascending or descending aorta. The diagnosis is often made in a neonate or an infant as a result of a weak femoral pulse or asymmetric brisk brachial pulses. Hypertension occurs as a result of a reduction in the effective circulation at the level of the kidneys which respond by increasing plasma volume which in turn causes hypertension in the upper extremities. Diagnosis is by CT angiography, but can also be made in neonates and infants by ultrasound of the heart and the great vessels. Definitive treatment is by surgical correction and or stenting.

Cushing’s Syndrome

Cushing's syndrome is an endocrine disorder caused by prolonged exposure to high endogenous or exogenous cortisol levels. Hypertension in Cushing’s syndrome has been classically attributed to the mineralocorticoid effects of cortisol. It manifests as an absent fall of nocturnal blood pressure physiologically seen in normotensive subjects with associated disturbance in the adrenocorticotropic hormone-glucocorticoid system.^[21] Symptoms of Cushing's syndrome include rapid weight gain, particularly of the trunk and face with sparing of the limbs (central obesity), a round face often referred to as a "moon face" along with central obesity, excess sweating, proximal muscle weakness, ecchymoses, insomnia, reduced libido, impotence, amenorrhoea, infertility and psychological disturbances, ranging from euphoria to psychosis. Depression and anxiety.^[22] Although an ideal diagnostic test is not considered yet available, clinicians often assess the 24-hour urinary cortisol excretion^[23], a low-dose dexamethasone suppression test^[24], late evening serum or salivary cortisol^[25], and a CRH a following a dexamethasone suppression test to establish the diagnosis.^[26]

Drugs

An extensive list of drugs can be associated with hypertension. The most common agents include immunosuppressive agents, non-steroidal anti-inflammatory drugs, oral contraceptive pills, some weight loss agents, stimulants, monoamine oxidase inhibitors, triptans, ergotamines, and sympathomimetics.^[1]

Diet

In addition to the association of obesity with hypertension, the 2001 study “Effects on Blood Pressure of Reduced Dietary Sodium and the Dietary Approaches to Stop Hypertension (DASH) Diet” concluded that a high sodium diet above the recommended 100 mmol per day (2.4 g of sodium or 6 g of sodium chloride salt) is associated with hypertension. As a result, reduction of sodium levels below 100 mmol per day and following the DASH diet (rich in vegetables, fruits, with low-fat dairy products) can significantly lower BP.^[27] Ingestion of excessive amounts of liquorice can lead to elevation in the blood pressure.

Erythropoietin

Elevated erythropoietin is typically seen in COPD patients who have functional anemia due to chronic hypoxia and in hematologic disorders such as polycythemia. The pathogenesis of erythropoietin-induced hypertension includes increased hematocrit and blood viscosity, altered sensitivity to vasopressors, dysregulated vasodilatory factors, and vascular cell growth causing arterial remodeling and changes in arterial smooth musculature.^[28] Diagnosis and treatment are etiology-dependent.

Endocrine

In addition to the more common endocrine causes of hypertension such as hyperaldosteronism, Cushing’s syndrome, and pheochromocytoma, several other endocrine changes can cause hypertension. Both hypothyroidism and hyperthyroidism can cause hypertension by volume retention and by increased cardiac output, respectively. Also, hyperparathyroidism and hypovitaminosis D can cause hypertension due to poorly understood mechanisms, where parathyroidectomy seems to significantly decrease blood pressure in patients with parathyroid disease and elevated BP.^[29] Acromegaly can also be a cause of hypertension.

-====Accuracy:====
+=====Accuracy=====
+An accurate assessment and re-assessment of blood pressures is an essential first step when a patient presents with high blood pressure.  The accuracy of home BP measurements should be confirmed by calibrating the patient's measurement technique with that obtained in the doctor's office.
-It refers to inappropriate technique to measure blood pressure. Re-measurement of blood pressures to ensure accuracy must always be performed as a first step when patients present with high blood pressure values. Appropriate measurement technique must be carefully followed. The physician in charge should check for the accuracy of home BP measurements.
-====Apnea:====
-Obstructive sleep apnea (OSA) is a respiratory disease due to repetitive narrowing or collapse of the upper airway during sleep<ref name="pmid18250206">{{cite journal| author=Eckert DJ, Malhotra A| title=Pathophysiology of adult obstructive sleep apnea. | journal=Proc Am Thorac Soc | year= 2008 | volume= 5 | issue= 2 | pages= 144-53 | pmid=18250206 | doi=10.1513/pats.200707-114MG | pmc=PMC2628457 | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=18250206  }} </ref> leading to apnea, hypopnea, and decreased oxygen tension at night (Ref: 8872797).

-Catecholamine excess is witnessed in several non-disease states, such as acute stress, medications with sympathomimetic activity, and illicit drug use such as cocaine. Nonetheless, such conditions can be ruled out by mere history taking. Pheochromocytoma is a tumor of the adrenal gland leading to hypersecretion of epinephrine in most cases, should always be considered in the differential diagnosis of secondary hypertension, classically in young patients with the triad of intermittent hypertensive episodes causing headache, sweating, and tachycardia. Nonetheless, pheochromocytoma in older adults or a presentation with sustained hypertension is not uncommon. Diagnosis of pheochromocytoma remains controversial.

-Coarctation of the aorta is a congenital heart defect, caused by narrowing of a segment in the ascending or descending aorta. Diagnosis in neonates or infants usually starts with a suspicious physical examination of weak femoral pulses or asymmetrically brisk brachial pulses. Hypertension occurs as a result of decreased effective circulation at the level of the kidneys; the latter respond physiologically by increasing plasma volume causing hypertension in the upper extremities. Diagnosis is by CT angiography, but is usually achieved in neonates and infants by ultrasound of the heart and the great vessels. Definitive treatment is by surgical correction.

+=====Catecholamines=====
-====Drugs:====
+Catecholamine excess occurs in several non-disease states, such as acute [[stress]], the administration of medications with sympathomimetic activity, and illicit drug use such as [[cocaine]] and these conditions can be ruled out by thorough history taking. [[Pheochromocytoma]], a tumor of the adrenal gland leading to excess secretion of [[epinephrine]], should be considered in young patients with the triad of intermittent hypertensive episodes causing [[headache]], [[sweating]], and [[tachycardia]]. However, [[pheochromocytoma]] in older adults or a presentation with sustained hypertension is not uncommon. Diagnostic studies to evaluate pheochromocytoma include measurement of plasma free [[metanephrines]] and urinary fractionated metanephrines.  The diagnostic value of plasma and urinary catecholamines is of limited value given the very short half-life of catecholamines.  Treatment is usually by surgical resection of the secreting tumor with appropriate adrenergic blockade.<ref name="pmid11903030">{{cite journal| author=Lenders JW, Pacak K, Walther MM, Linehan WM, Mannelli M, Friberg P et al.| title=Biochemical diagnosis of pheochromocytoma: which test is best? | journal=JAMA | year= 2002 | volume= 287 | issue= 11 | pages= 1427-34 | pmid=11903030 | doi= | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=11903030  }} </ref>

+=====Coarctation=====
+[[Coarctation of the aorta]] is a [[congenital heart defect]], caused by a narrowing in a segment of the ascending or [[descending aorta]].  The diagnosis is often made in a neonate or an infant as a result of a weak femoral pulse or asymmetric brisk brachial pulses.  [[Hypertension]] occurs as a result of a reduction in the effective circulation at the level of the [[kidneys]] which respond by increasing plasma volume which in turn causes hypertension in the upper extremities.  Diagnosis is by [[CT angiography]], but can also be made in neonates and infants by ultrasound of the heart and the great vessels. Definitive treatment is by surgical correction and or stenting.
