The History and Development of the Jnc 8 Guidelines
The Jnc 8 guidelines are the latest version of the clinical practice guidelines for the management of high blood pressure in adults, developed by a panel of experts appointed by the National Heart, Lung, and Blood Institute (NHLBI). The acronym Jnc stands for Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure.
The first Jnc report was published in 1977 and since then, there have been seven updates until 2003. The Jnc guidelines are based on a systematic review of the best available scientific evidence and aim to provide practical and evidence-based recommendations for clinicians and patients.
The Jnc 8 guidelines were published in 2014, after a long delay and a controversial process. Unlike the previous versions, which were endorsed by several professional organizations, such as the American Heart Association (AHA) and the American College of Cardiology (ACC), the Jnc 8 guidelines were only published as a report in the Journal of the American Medical Association (JAMA) by some members of the original panel. This was because the NHLBI decided to discontinue developing clinical practice guidelines in 2013 and transferred its responsibility to other organizations.
The main changes and updates in the Jnc 8 guidelines compared to the previous versions are:
The use of a more rigorous and transparent method for selecting and grading the evidence.
The simplification of the blood pressure categories from six to four: normal, prehypertension, stage 1 hypertension, and stage 2 hypertension.
The relaxation of some blood pressure targets, especially for older adults (age 60 years) and patients with diabetes or chronic kidney disease.
The emphasis on individualized treatment decisions based on patient preferences, comorbidities, and risk factors.
The reduction of the number of antihypertensive drug classes recommended as initial therapy from four to three: thiazide-type diuretics, calcium channel blockers (CCBs), and angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs).
The Key Recommendations and Evidence of the Jnc 8 Guidelines
The Jnc 8 guidelines are based on four main questions and answers that address the most important aspects of hypertension management. These are:
1. In adults with hypertension, does initiating antihypertensive pharmacologic therapy at specific blood pressure thresholds improve health outcomes?
The panel recommends initiating antihypertensive pharmacologic therapy in adults aged 60 years or older with systolic blood pressure (SBP) 150 mm Hg or diastolic blood pressure (DBP) 90 mm Hg, and in adults aged
2. In adults with hypertension, does treatment with antihypertensive pharmacologic therapy to a specified blood pressure goal lead to improvements in health outcomes?
The panel recommends treating adults aged 60 years or older to a blood pressure goal of
3. In adults with hypertension, do various antihypertensive drugs or drug classes differ in comparative benefits and harms on specific health outcomes?
The panel recommends starting treatment with any of the following three drug classes: thiazide-type diuretics, CCBs, or ACEIs/ARBs. The panel also recommends choosing a specific drug class based on the patient's race and comorbidities. For example, the panel recommends using a thiazide-type diuretic or CCB for black patients, and an ACEI or ARB for patients with chronic kidney disease.
4. In adults with hypertension, what are the optimal strategies for starting and adding antihypertensive drugs to achieve blood pressure control?
The panel recommends starting with one drug and titrating the dose as needed to achieve blood pressure control. If the goal is not reached with one drug, the panel recommends adding a second drug from one of the recommended classes. If the goal is still not reached with two drugs, the panel recommends adding a third drug from one of the recommended classes. The panel does not recommend using an ACEI and an ARB together in the same patient.
The evidence and rationale behind each recommendation are explained in detail in the Jnc 8 report. The panel used a standardized method to rate the quality and strength of the evidence, based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. The panel also considered the benefits and harms, values and preferences, and costs of each intervention.
The Jnc 8 guidelines differ from other guidelines, such as those from the AHA/ACC or the European Society of Hypertension (ESH)/European Society of Cardiology (ESC), in some aspects. For example, the Jnc 8 guidelines have higher blood pressure thresholds and goals for older adults, while other guidelines recommend lower targets for all age groups. The Jnc 8 guidelines also have fewer drug classes recommended as initial therapy, while other guidelines include beta-blockers, alpha-blockers, and renin inhibitors as options.
The Benefits and Limitations of the Jnc 8 Guidelines
The Jnc 8 guidelines have several advantages and disadvantages for hypertension management. Some of the benefits are:
The Jnc 8 guidelines are based on a rigorous and transparent review of the best available evidence, which increases their credibility and validity.
The Jnc 8 guidelines are simple and easy to follow, which may improve their adherence and implementation by clinicians and patients.
The Jnc 8 guidelines are flexible and individualized, which allows for tailoring the treatment to each patient's characteristics and preferences.
The Jnc 8 guidelines are consistent with the principle of parsimony, which means using the minimum number of interventions necessary to achieve the desired outcome.
The Jnc 8 guidelines may reduce the risk of overtreatment and adverse effects associated with lower blood pressure targets and more aggressive drug regimens.
Some of the limitations are:
The Jnc 8 guidelines are not endorsed by any professional organization, which may limit their acceptance and dissemination among clinicians and patients.
The Practical Application and Implementation of the Jnc 8 Guidelines
The Jnc 8 guidelines are intended to be used as a guide for clinical decision making and not as a substitute for clinical judgment. The panel acknowledges that there may be situations where the recommendations may not apply or may need to be modified based on the patient's individual circumstances. Therefore, the panel encourages clinicians and patients to engage in a shared decision making process and to consider the patient's values, preferences, goals, and comorbidities when choosing a treatment plan.
The panel also recognizes that the implementation of the Jnc 8 guidelines may pose some challenges and barriers in the real-world setting. Some of these challenges are:
The lack of awareness and familiarity with the Jnc 8 guidelines among clinicians and patients.
The resistance and inertia to change from the previous practices and habits.
The variability and inconsistency in the measurement and diagnosis of blood pressure.
The availability and affordability of the recommended drugs and devices.
The adherence and persistence to the prescribed treatment regimen.
The monitoring and evaluation of the treatment outcomes and adverse effects.
To overcome these challenges and facilitate the implementation of the Jnc 8 guidelines, the panel suggests some steps and strategies, such as:
Educating and informing clinicians and patients about the Jnc 8 guidelines and their rationale.
Providing feedback and reminders to clinicians and patients about the Jnc 8 guidelines and their goals.
Using standardized and accurate methods for measuring and recording blood pressure.
Prescribing generic and low-cost drugs whenever possible and appropriate.
Using combination pills or fixed-dose formulations to simplify the drug regimen.
Empowering and motivating patients to self-monitor their blood pressure and adhere to their treatment plan.
Using electronic health records, registries, or other tools to track and audit the performance and quality of care.
In addition, the panel recommends using some tools and resources that can help with the application and implementation of the Jnc 8 guidelines. Some of these tools and resources are:
The Jnc 8 report itself, which contains detailed explanations, tables, figures, algorithms, references, and appendices related to the Jnc 8 guidelines.
The Jnc 8 pocket card, which summarizes the main recommendations, evidence ratings, blood pressure thresholds and goals, drug classes, dosages, and special considerations of the Jnc 8 guidelines in a concise and handy format.
The Jnc 8 smartphone app, which provides an interactive and user-friendly interface for accessing and applying the Jnc 8 guidelines on mobile devices.
The NHLBI website, which offers various information and materials related to hypertension prevention and management, such as fact sheets, brochures, videos, podcasts, webinars, calculators, quizzes, etc.
The AHA website, which provides various resources and programs related to cardiovascular health promotion and disease prevention, such as guidelines, scientific statements, journals, conferences, courses, campaigns, initiatives, etc.

Are the Jnc 8 guidelines still valid?
The Jnc 8 guidelines are still valid and widely used by many clinicians and patients. However, they are not endorsed by any professional organization and they may not reflect the most recent evidence and developments in hypertension management. Therefore, they should be used with caution and discretion, and supplemented by other sources of information and guidance.
What are the alternatives to the Jnc 8 guidelines?
Some of the alternatives to the Jnc 8 guidelines are the guidelines from the AHA/ACC or the ESH/ESC, which have lower blood pressure thresholds and goals for all age groups, more drug classes recommended as initial therapy, and more specific and prescriptive recommendations. However, these guidelines also have their own strengths and weaknesses, and they may not be applicable or suitable for every patient or situation.
How can I lower my blood pressure without medication?
Some of the lifestyle modifications that can help lower your blood pressure without medication are:
Eating a healthy diet that is low in salt, fat, and sugar, and high in fruits, vegetables, whole grains, and lean proteins.
Exercising regularly for at least 30 minutes a day, five days a week, preferably aerobic activities that increase your heart rate and breathing.
Maintaining a healthy weight that is appropriate for your height and body type.
Quitting smoking or avoiding exposure to secondhand smoke.
Limiting alcohol intake to no more than one drink a day for women and two drinks a day for men.
Managing stress by using relaxation techniques, such as meditation, yoga, breathing exercises, etc.
How can I monitor my blood pressure at home?
You can monitor your blood pressure at home by using a home blood pressure monitor, which is a device that measures your blood pressure through a cuff that wraps around your arm. You can buy a home blood pressure monitor at a pharmacy or online. You should follow these steps when using a home blood pressure monitor:
Choose a monitor that is validated, accurate, and easy to use. You can check the validation status of a monitor on this website.
Choose a cuff that fits your arm size. You can measure your arm circumference with a tape measure and compare it with the cuff size chart on the monitor's manual or box.
Prepare for the measurement by avoiding eating, drinking, smoking, exercising, or using the bathroom for at least 30 minutes before taking your blood pressure.
Sit comfortably in a chair with your back supported and your feet flat on the floor. Rest your arm on a table at the level of your heart. Relax for at least five minutes before taking your blood pressure.
Wrap the cuff around your upper arm, about one inch above your elbow. Make sure the cuff is snug but not too tight. Align the cuff's tube with the center of your inner arm.
Press the start button on the monitor and wait for it to inflate and deflate the cuff. Do not talk or move during the measurement.
Record your blood pressure reading on a paper or an app. Repeat the measurement after one minute and record it again. Take the average of the two readings as your blood pressure value.
Compare your blood pressure value with the thresholds and goals of the Jnc 8 guidelines or other guidelines that you follow. If your blood pressure is high or low, consult your doctor for advice.
