2013 Practice guidelines for the management of arterial hypertension of the European Society of Hypertension (ESH) and the European Society of Cardiology (ESC): ESH/ESC Task Force for the Management of Arterial Hypertension.
Summary (3 min read)
1. INTRODUCTION
- These 2018 European Society of Cardiology/European Society of Hypertension (ESC/ESH) guidelines for the management of arterial hypertension are designed for adults with hypertension, i.e. aged ≥18 years.
- The purpose of the review and update of these guidelines was to evaluate and incorporate new evidence into the guideline recommendations.
- The specific aims of these guidelines were to produce pragmatic recommendations to improve the detection and treatment of hypertension, and to improve the poor rates of BP control by promoting simple and effective treatment strategies.
1.1. Principles
- (i) to base recommendations on properly conducted studies, identified from an extensive review of the literature; (ii) to give the highest priority to data from randomized, controlled trials (RCTs); (iii) to also consider well-conducted meta-analyses of RCTs as strong evidence, also known as These fundamental principles are.
- In these circumstances, the authors resort to pragmatic expert opinion and endeavour to explain its rationale.
1. 3 New concepts
- BP measurement - Wider use of out-of-office BP measurement with ABPM and/or HBPM, especially HBPM, as an option to confirm the diagnosis of hypertension, detect white coat and masked hypertension and monitor BP control.
- Less conservative treatment of BP in older and very old patients - Lower BP thresholds and treatment targets for older patients – with emphasis on considerations of biological rather than chronological age (i.e. the importance of frailty, independence, and the tolerability of treatment).
- A SPC treatment strategy to improve BP control - Preferred use of two-drug combination therapy for the initial treatment of most people with hypertension. - A single-pill treatment strategy for hypertension with the preferred use SPC therapy for most patients.
- - Simplified drug-treatment algorithms with the preferred use of an ACE inhibitor or ARB combined with a CCB or/and a thiazide/thiazide-like diuretic as the core treatment strategy for most patients, with beta-blockers used for specific indications.
- The important role of nurses and pharmacists in the education, support, and follow-up of treated hypertensive patients is emphasized as part of the overall strategy to improve BP control.
2. Definitions and classifications
- The relationship between BP and CV and renal events is continuous, making the distinction between normotension and hypertension − based on cut-off BP values − somewhat arbitrary.
- This evidence has been reviewed and provides the basis for the recommendation that the classification of BP and definition of hypertension remain unchanged from previous ESH/ESC guidelines.
3.1 Evaluation of the CV risk
- Many CV risk-assessment systems are available and most project 10-year risk.
- Since 2003, the European guidelines on CVD prevention have recommended use of the Systematic COronary Risk Evaluation system because it is based on large, representative European cohort datasets (available at: http://www.escardio.org/Guidelines-&-Education/Practice-tools/CVD-preventiontoolbox/-Risk-Charts).
- The SCORE system only estimates the risk of fatal CV events.
3.2 Measurement of blood pressure
- Auscultatory or oscillometric semiautomatic or automatic sphygmomanometers are the preferred method for measuring BP in the doctor’s office.
- These devices should be validated according to standardized conditions and protocols.
- In white-coat hypertension, the difference between the higher office and the lower out-of-office BP is referred to as the “white-coat effect”, and is believed to mainly reflect the pressor response to an alerting reaction elicited by office BP measurements by a doctor or a nurse, although other factors are probably also involved.
- These guidelines also support the use of out-of-office BP (i.e. HBPM and/or ABPM) as an alternative strategy to repeated office BP measurements, to confirm the diagnosis of hypertension, when these measurements are logistically and economically feasible.
- All adults should have their BP recorded in their medical record and be aware of their BP, and further screening should be undertaken at regular intervals with the frequency dependent on the BP level as illustrated in Figure 10.
4. Treatment of hypertension
- The routine treatment of hypertension involves lifestyle interventions for all patients (including those with high normal BP) and drug therapy for most patients.
- All guidelines agree that patients with grade 2 or 3 hypertension should receive antihypertensive drug treatment alongside lifestyle interventions.
- Guidelines are also consistent in recommending that patients with grade 1 hypertension and high CV risk or HMOD should be treated with BP-lowering drugs.
- There has been less consistency about whether BP-lowering drugs should be offered to patients with grade 1 hypertension and low-to-moderate CV risk or grade 1 hypertension in older patients (> 60 years), or the need for BP-lowering drug treatment in patients with high-normal BP levels.
- This uncertainty relates to the fact that low-risk patients with high-normal BP or grade 1 hypertension have rarely been included in RCTs, and that in older patients, RCTs have invariably recruited patients with at least grade 2 hypertension.
4.1 Drug treatment strategy and blood pressure targets (Figure 15-20)
- Figure 16: Summary of office BP thresholds for treatment CAD: coronary artery disease; CKD: chronic kidney disease; SBP: systolic blood pressure; TIA: transient ischaemic attack.
- Figure 17: Office BP treatment targets in hypertensive: recommendations.
- The level to which BP should be lowered with drug treatment will depend on the patients’ age, comorbidities and tolerability of treatment.
- The core algorithm is also appropriate for most patients with HMOD, cerebrovascular disease, diabetes, or peripheral artery disease.
4.4. Resistant hypertension (Figures 26 and 27)
- Hypertension is defined as resistant to treatment when the recommended treatment strategy fails to lower office SBP and DBP values to below 140 mmHg and/or 90 mmHg, respectively, and the inadequate control of BP is confirmed by ABPM or HBPM, in patients whose adherence to therapy has been confirmed.
- The recommended treatment strategy should include appropriate lifestyle measures and treatment with optimal or best-tolerated doses of three or more drugs that should include a diuretic and typically an ACE inhibitor or ARB, and a CCB.
5.1 Frequency of visits
- After the initiation of antihypertensive drug therapy, it is important to review the patient at least once within the first 2 months to evaluate the effects on BP and assess possible side-effects until BP is under control.
- The frequency of review will depend on the severity of hypertension, the urgency to achieve BP control, and the patient’s comorbidities.
- Patients with high-normal BP or white-coat hypertension frequently have additional risk factors, including HMOD, and have a higher risk of developing sustained hypertension.
- Thus, even when untreated, they should be scheduled for regular follow-up (at least annual visits) to measure office and out-of-office BP, as well as to check the CV risk profile.
5.2 Adherence to therapy (Figure 43)
- Non-adherence to antihypertensive therapy correlates with higher risk of CV events.

Frequently Asked Questions (12)
Q2. What are the main factors contributing to poor BP control?
Physician inertia (inadequate up-titration of treatment, especially from monotherapy) and poor patient adherence to treatment (especially when based on multiple pills) are now recognised as the major factors contributing to poor BP control.
Q3. What is the preferred method for measuring BP in the doctor’s office?
Auscultatory or oscillometric semiautomatic or automatic sphygmomanometers are the preferred method for measuring BP in the doctor’s office.
Q4. What are the main factors in determining the tolerability of BP-lowering medications?
It is increasingly recognised that biological rather than chronological age, as well as consideration of frailty and independence, are important determinants of the tolerability of and likely benefit from BP-lowering medications.
Q5. What is the important cause of poor BP control?
There is growing evidence that poor adherence to treatment − in addition to physician inertia (i.e. lack of therapeutic action when the patient’s BP is uncontrolled) − is the most important cause of poor BP control.
Q6. What is the preferred strategy for BP control?
SPC therapy is now the preferred strategy for initial two-drug combination treatment of hypertension and for three-drug combination therapy when required.
Q7. What is the current recommendation for patients with BP?
The authors now recommend that patients with low−moderate risk grade 1 hypertension (office BP 140–159/90–99), even if they do not have HMOD,should now receive drug treatment if their BP is not controlled after a period of lifestyle intervention alone.
Q8. What is the evidence to support lowering the BP?
The evidence strongly suggests that lowering office SBP to < 140 mmHg is beneficial for all patient groups, including independent older patients.
Q9. What is the purpose of the review and update of these guidelines?
The purpose of the review and update of these guidelines was to evaluate and incorporate new evidence into the guideline recommendations.
Q10. What is the role of BP lowering in hypertensive patients?
For hypertensive patients at moderate CVD risk or higher, or those with established CVD, BP lowering alone will not optimally reduce their risk.
Q11. What is the level of BP that should be lowered with drug treatment?
The level to which BP should be lowered with drug treatment will depend on the patients’ age, comorbidities and tolerability of treatment.
Q12. What is the important factor in determining the magnitude of BP?
The rate and magnitude of increase in BP may be at least as important as the absolute level of BP in determining the magnitude of organ injuryAfter the initiation of antihypertensive drug therapy, it is important to review the patient at least once within the first 2 months to evaluate the effects on BP and assess possible side-effects until BP is under control.
