Symptoms of Hypertension:

Measuring blood pressure[3]
Use a correctly calibrated and maintained machine (manual or automatic).
Seated BP is adequate except in elderly patients or those with diabetes who may have orthostatic hypotension (standing BP is needed as well - after at least one minute's standing). If standing systolic blood pressure (SBP) is 20 mm Hg or lower than when seated, review medication, and measure all subsequent blood pressures with the person standing (consider specialist referral if postural hypotension symptoms persist).
Remove tight clothing and support the arm with the hand relaxed and the cuff (of appropriate size) at heart level.
Initially, measure BP in both arms; if there is a persistent difference of >20 mm Hg between arms then ensure subsequent blood pressures are taken in the arm with the higher reading.
Use an automated machine or the following manual method (if the pulse is irregular (eg, in atrial fibrillation), always use the manual method):
Inflate the cuff whilst palpating the brachial artery, until the pulse disappears. This provides an estimate of systolic pressure.
Inflate the cuff until 30 mm Hg above systolic pressure, then place a stethoscope over the brachial artery. Deflate the cuff at 2 mm Hg per second.
Systolic pressure: the appearance of sustained repetitive tapping sounds (Korotkov I). Diastolic pressure: usually the disappearance of sounds (Korotkov V). However, in some individuals (eg, pregnant women) sounds are present until the zero point. In this case the muffling of sounds,(Korotkov IV), should be used.
Record to the nearest 2 mm Hg.
If initial BP is ≥140/90 mm Hg, take a second or even third reading and record the lowest (discard the initial reading) as the clinic BP.
If BP in the GP surgery is ≥140/90 mm Hg then offer ambulatory blood pressure monitoring (ABPM) to confirm the suspected hypertension, or home blood pressure monitoring (HBPM) if ABPM is not available or not tolerated.[3]

If using ABPM - take ≥2 readings every waking hour, and average at least 14 measurements when deciding whether hypertension is present.
If using HBPM - on each occasion take two consecutive BP measurements (<1 minute apart), with the person seated. Take readings twice daily (morning and evening) over ≥4 days (ideally 7 days) - disregard the first day and then average the rest.
Those with high normal values (130-139/85-89 mm Hg) subsequently should be checked annually.

While waiting for further BP readings to confirm diagnosis of hypertension, look for target organ damage and carry out cardiovascular risk assessment with a suitable assessment tool - look for hypertensive retinopathy, left ventricular hypertrophy on ECG, and perform blood tests (serum electrolytes, creatinine, eGFR, fasting glucose and lipids) and urinalysis for albuminuria, proteinuria or haematuria ± albumin:creatinine ratio.

Defining hypertension[3]
Blood pressure (BP) has a skewed normal distribution within the population and the currently accepted model assumes risk is continuously related to BP. The National Institute for Health and Care Excellence (NICE) recommends the following definitions:

Stage 1 hypertension - BP in surgery/clinic is ≥140/90 mm Hg and ABPM or HBPM is ≥135/85 mm Hg.
Stage 2 hypertension - BP in surgery/clinic  is ≥160/100 mm Hg and ABPM or HBPM is ≥150/95 mm Hg.
Severe hypertension - BP in surgery/clinic is ≥180/110 mm Hg or higher.

Other considerations
Hypertensive crisis: there are two types
Malignant (accelerated) hypertension: this is a syndrome characterised by severe hypertension (eg, systolic >200 mm Hg, diastolic >130 mm Hg) accompanied by end-organ damage - eg, encephalopathy, dissection, pulmonary oedema, nephropathy, eclampsia, papilloedema and/or angiopathic haemolytic anaemia. Accelerated hypertension needs urgent (same day) assessment and immediate treatment to reduce the BP within minutes to hours.[3]This is also termed hypertensive emergency.
Hypertensive urgency:  a systolic blood pressure (SBP) ≥180 mm Hg or a diastolic blood pressure (DBP) ≥120 mm Hg without impending end-organ damage. Treatment should safely reduce BP over a few days.
Suspected phaeochromocytoma: consider this diagnosis if there is labile or postural hypotension, headache, palpitations, pallor and profuse sweating - refer for urgent (same day) assessment.[3][4] This is also termed urgent hypertension.
Systolic or diastolic pressure: for many years diastolic pressure was considered to be more important than systolic pressure.  They are both important determinants of cardiovascular risk.
Hypertension in the elderly: although age-related, rise in systolic pressure can be considered part of the 'normal' ageing process; isolated systolic hypertension (ISH) in the elderly should not be ignored. The benefits of treatment are far greater than treating moderate hypertension in middle-aged patients.[5]

Aetiology
Essential hypertension (primary, cause unknown) accounts for the majority of cases, particularly in the older patient.
Secondary hypertension is commonly caused by renal disease or pregnancy:
Renal disease - approximately 75% are from intrinsic renal disease: glomerulonephritis, polyarteritis nodosa, systemic sclerosis, chronic pyelonephritis, or polycystic kidneys.
Approximately 25% are due to renovascular disease - most frequently atheromatous (eg, elderly cigarette smokers with peripheral vascular disease) or fibromuscular dysplasia (more common in younger females).
Endocrine disease:[4]
Cushing's syndrome
Conn's syndrome
Phaeochromocytoma
Acromegaly
Hyperparathyroidism
Coarctation.
Pre-eclampsia and hypertension in pregnancy.[6]
Drugs and toxins - eg, alcohol, cocaine, ciclosporin, tacrolimus, erythropoietin, adrenergic medications, decongestants containing ephedrine and herbal remedies containing licorice.
Presentation
It is usually asymptomatic, except accelerated hypertension.

All patients need a full history and physical examination. Look hard for a cause (renal, endocrine, etc. - as above) in the young, severe hypertensive and those with resistant hypertension.[4][7][8]

Take a full drug history (non-steroidal anti-inflammatory drugs (NSAIDs), oral contraceptives, steroids, licorice, sympathomimetics, ie cold cures).
Are they aware of the hypertension? Episodic feelings 'as if about to die' or headaches, or paroxysmal sweats or palpitations, suggest phaeochromocytoma.
Consider renal causes: is there a present, past or family history of renal disease? Are the kidneys palpable? Is there an abdominal or loin bruit (renovascular disease) or delayed or weak femoral pulses (coarctation).
Does the patient look Cushingoid or might he or she have Conn's syndrome (tetany, weak muscles, polyuria, hypokalaemia)?
Consider contributory factors: obesity, excess alcohol, salt intake[9] and lack of exercise, environmental stress, and cardiovascular risk factors (smoking, diabetes, cholesterol and family history) ready for your management plan.
Assess the degree of end-organ damage or complications of hypertension - eg, previous CVE, transient ischaemic attack (TIA), dementia or known left ventricular hypertrophy (LVH)/left ventricular (LV) strain, IHD, peripheral vascular disease, or renal impairment. Perform ophthalmoscopy; dilate with 1% tropicamide if there is poor view.

Investigations
Looking for target-organ damage:[4]
Urine dipstick test for protein and blood.
Serum creatinine and electrolytes and eGFR.
Renal ultrasound scan.
12-lead ECG (looking for LVH or signs of IHD).
Echocardiography.
Cardiovascular disease prevention:
Fasting blood glucose.
Fasting serum total and high-density lipoprotein (HDL) cholesterol.
Specific investigations for a suspected secondary cause:[4]
24-hour urinary metanephrines.
Urinary free cortisol and/or dexamethasone suppression test.
Renin/aldosterone levels.
Plasma calcium.
Magnetic resonance imaging of the renal arteries.
Referral to a specialist may be appropriate for some of these tests.

Indications for referral to a specialist[10]
Urgent treatment is needed: accelerated hypertension, severe hypertension (>220/>120 mm Hg) or impending complications (eg, TIA, LV failure).
Possible underlying cause: low K+, Na+ elevated (possible Conn's syndrome); elevated creatinine, proteinuria or haematuria; sudden onset or rapidly worsening or resistant hypertension (ie needs >3 drugs); young age: patient aged <20 years, or <30 years needing treatment.
Therapeutic problems: multiple drug intolerance or contra-indications, persistent non-compliance or treatment refusal (the reluctant hypertensive).
Special situations: hypertension in pregnancy,[6] unusual BP variability.

Sign Of  Hypertension:

High blood pressure is a common and dangerous condition. Having high blood pressure means the pressure of the blood in your blood vessels is higher than it should be. But you can take steps to control your blood pressure and lower your risk of heart disease and stroke.

About 1 of 3 U.S. adults—or about 70 million people—have high blood pressure.1 Only about half (52%) of these people have their high blood pressure under control.1 This common condition increases the risk for heart disease and stroke, 2 of the leading causes of death for Americans.2 Get more quick facts about high blood pressure, or learn more about high blood pressure in the United States.

High blood pressure is called the "silent killer" because it often has no warning signs or symptoms, and many people do not know they have it. That's why it is important to check your blood pressure regularly.


The good news is that you can take steps to prevent high blood pressure or to control it if your blood pressure is already high.

High blood pressure is called the "silent killer" because it often has no warning signs or symptoms, and many people do not know they have it.

Rarely, high blood pressure can cause symptoms like headaches or vomiting.

There's only one way to know whether you have high blood pressure—have a doctor or other health professional measure it. Measuring your blood pressure is quick and painless.
Hypertension is often symptomless, so screening is vital - before damage is done. Many surveys continue to show that hypertension remains underdiagnosed, undertreated and poorly controlled in the UK.[1] Overall, the prevalence of hypertension (at least ≥140/90 mm Hg or on treatment for hypertension) in those aged over 35 was 31% in men and 28% in women
The prevalence significantly increased with age in both sexes

About 33% of men and 25% of women aged 45-54 years have hypertension.
About 66% of men and 78% of women aged ≥75 years or older have hypertension.
Screening for hypertension
All adults should have their blood pressure (BP) measured, at least every five years up to the age of 80, and at least annually thereafter.
