                                                                                      1
Hypertension is one of the major health issues facing our country. In 2007, 5.7 million
Canadians had been diagnosed with hypertension and just over 5 million were on
pharmacotherapy (1). For the last decade, hypertension has been the leading diagnosis for
adult visits to physicians and the proportion of total visits to a physician for hypertension is
increasing (2). The World Health Organization has indicated that increased blood pressure is
the leading risk for death, predicting an epidemic of hypertension and is advocating for
prevention and treatment programs as a priority (3;4). Worldwide over 7 million deaths in the
year 2000 were attributed to sub optimum blood pressure and increased blood pressure is
estimated to consume 10% of health care costs in developed countries like Canada(5;6).

2010 marks the 11th consecutive year that the Canadian Hypertension Education Program
(CHEP) has updated recommendations for the management of hypertension. CHEP was
developed to assist primary care providers in better managing and preventing hypertension.
As evidenced by the recent population-based surveys, Canada is one of the world’s leading
country in the prevention and control of hypertension (7). A decrease in cardiovascular
disease rates occurred concurrent with the increase in treatment of hypertension and the
CHEP program in 1999 (8;9). The success of the CHEP program is evidenced by the fact
that most developed countries have hypertension control rates well below those achieved in
Canada (10).

Nevertheless there is still much progress that can be made in Canada to further reduce
premature cardiovascular death and disability by improving hypertension management.
Recent (unpublished) surveys have found that many health care professionals are still not
aware of CHEP or its recommendations. Therefore special efforts are being made to increase
the accessibility to hypertension resources. In 2010 health care professionals can enroll at
www.htnupdate.ca to get automated email notices when new or updated hypertension
resources are available for them or their patients. They can also download current resources
at www.hypertension.ca/tools. A case-based interactive lecture series on clinically important
hypertension topics will also be launched on the internet so health care professionals can
learn and interact with top national hypertension experts. The lecture series will feature
important clinical topics provided by national experts, have a case presentation and an
opportunity to ask questions and make comments. The lectures can be watched wherever
there is internet coverage. Sign up at www.htnupdate.ca to be notified when they start.
CHEP will also continue and expand a program to train community leaders in hypertension.
Table 1 and 2 indicate current hypertension resources that are available for health care
professionals and people with hypertension.

Hypertension Canada will be developing a hypertension association for Canadians with high
blood pressure. Encourage your patients to sign up for 2010 membership at
www.myBPsite.ca. Members will receive notices of updated and new educational resources,
a regular newsletter, discount coupons to encourage a healthy lifestyle, lectures and possibly
in the future personalized health care professional advice. Members will be provided
opportunities to provide advice on the need for new hypertension resources and revise
current blood pressure resources.


Areas of Clinical Hypertension Management in Canada that are emphasized by CHEP in
2010

Hypertension in People with Diabetes
                                                                                               2
Over 60% of people with diabetes die of cardiovascular disease and up to 75% of specific
diabetic complications are attributable to elevated blood pressure (11). Treating hypertension
in people with diabetes reduces premature death and disability by up to 50% (11). The current
target of less than 130/80 mmHg is important as more versus less intensive hypertension
treatment reduces premature death and cardiovascular events by 25% or more (12).
Combinations of lifestyle modification and 3 to 4 or more drugs may be required for blood
pressure control in persons with diabetes. The prescription of an angiotensin converting
enzyme inhibitor (ACE inhibitor) or angiotensin receptor blocker is recommended in all people
with diabetes who are hypertensive (Table 3). In the absence of micro or macro albuminuria, a
diuretic or a long acting calcium channel blocker is also a suitable first line drug therapy. If the
blood pressure is 150/90 mmHg or more, consider initiating therapy with a combination of two
drugs. Diuretic therapy is generally necessary for blood pressure control when multiple drugs
are used (13). Although many clinicians are uncomfortable prescribing diuretics to people with
diabetes, possibly because diuretics cause a small increase in blood glucose, diuretics have
been shown to be equally effective as ACE inhibitors in preventing cardiovascular
complications (14). Of note is that quality of life usually improves in the people treated to lower
blood pressure levels and treatment is cost saving because of the large reduction in
cardiovascular events (15-17).

Home measurement of blood pressure
Home measurement of blood pressure can increase patient self-efficacy and is recommended.
Home blood pressure readings more reliably predict the risk of cardiovascular outcomes than
readings taken in a health care professional’s office. Home blood pressure measurements can
be used to confirm the diagnosis of hypertension, to improve blood pressure control, to reduce
the need for medications in those with white coat effect, to identify those with white coat and
masked hypertension and to improve medication adherence (18). Patient instructions for
purchasing and using home blood pressure measurement can be found in Table 4 and at the
bottom of www.hypertension.ca/tools as well as at www.heartandstroke.ca/BP A
comprehensive instructional video on home measurement was developed in 2009 and can be
downloaded from www.hypertension.ca/video.

Automated office measurement of blood pressure
In 2010 CHEP is recommending consideration of the use of fully automated office blood
pressure devices. Automated office blood pressures are more closely correlated to
ambulatory blood pressure readings and to target organ damage than are manual readings.
A full review of office, home and ambulatory blood pressure recommendations is expected in
2011.

Combination of antihypertensive medications
Most people require lifestyle changes and multiple antihypertensive drugs. When using two
drugs to lower blood pressure combinations of a beta blocker, ACE inhibitor or angiotensin
receptor blocker produce less than additive hypotensive effect and should be avoided unless
there is a specific indication (e.g. heart failure) (19;20). If blood pressure is > 20/10 mmHg
above target initiating therapy with a combination of two ‘first line’ antihypertensive drugs is a
first line option (19). Use of a combination tablet that contains two medications can improve
adherence and lower drug costs relative to prescribing the two drugs separately and is
recommended to be considered.
CHEP recommends that the combination of an ACE inhibitor / calcium channel blocker based
therapy be considered when combination therapy is required in selected high risk patients. A
clinical trial was published in 2009 that showed an ACE inhibitor / calcium channel blocker
                                                                                                   3
regime was superior to an ACE inhibitor /thiazide diuretic based regime in hypertensive
patients who had prior vascular disease or who had other vascular risk factors (21). The trial
results generated considerable discussion and more subgroup analyses are expected. It is
hoped new trials will be done to validate the finding that some specific combinations of
antihypertensive drugs are superior to others given the strong evidence that all current first
line drugs have similar reductions in cardiovascular events in people with hypertension who
do not have compelling indications. In resistant hypertension, the use of a diuretic (and
sometimes high doses of diuretics) is usually required to achieve blood pressure control (13).

Angiotensin Receptor Blockers or ACE inhibitors in most People with Ischemic Heart
Disease
In many settings, ACE inhibitors and ARBs are interchangeable. In people with heart failure,
prior stroke or in chronic kidney disease ACE inhibitors are preferred (19). In 2010, CHEP
recommends that most people with hypertension and ischemic heart disease should be
treated with EITHER an ACE inhibitor or an angiotensin receptor blocker (19). Although
effective when used useful individually, the combination of ACE inhibitor and ARB therapy
should only be considered in selected and closely monitored people with advanced heart
failure or proteinuric nephropathy. CHEP specifically recommends not to combine an ACE
inhibitor with an angiotensin receptor blocker in people with uncomplicated hypertension,
diabetes (without micro or macro albuminuria), chronic kidney disease (without nephropathy
(micro or macro albuminuria) or ischemic heart disease (without heart failure) (19).

Reducing Dietary sodium to prevent and treat hypertension.
Given the linear association between sodium intake and blood pressure and the proven
benefits of low sodium diets, CHEP now recommends adults adhere to the government
recommended adequate intake (AI) levels of sodium (Table 5) (19). In the United States high
dietary sodium is estimated to be the 7th leading risk for death (22). A new trial of sodium
restriction reported a reduction in blood pressure of 22/9 mmHg in patients with blood
pressure above 140/90 mmHg while on three antihypertensive drugs who reduced sodium
intake to 1060 mg/day from 5796 mg/day (23). Advice on how to reduce sodium intake is
available in Table 6 and patients can obtain more detailed information at
www.lowersodium.ca or www.sodium101.ca. Health Canada will produce additional
information for the public and patients in 2010.

Key issues in the Management of the patient with hypertension:
Assess blood pressure at all appropriate visits. Blood pressure increases with age. Half
of Canadians over age 60 have hypertension and it is estimated that 9 in 10 of those with
normal blood pressure at age 55-65 will develop hypertension within an average lifespan (24).
All adults require ongoing assessment of blood pressure and Canadians with high normal
blood pressure require annual blood pressure assessment as over ½ will develop
hypertension within 4 years (25).

Assess and manage overall cardiovascular risk in all people with hypertension
including: smoking, unhealthy eating, physical inactivity, abdominal obesity,
dyslipidemia, and dysglycemia (e.g. glucose intolerance, diabetes). Approximately 9 in
10 hypertensive Canadians have other cardiovascular risks (26). Comprehensive screening
and management of other risk factors in addition to hypertension can double the reduction in
cardiovascular risk, lower the blood pressure target (Table 7) and change the types of
antihypertensive medications recommended (Table 3). Many people with multiple
cardiovascular risks or cardiovascular disease have uncontrolled blood pressures and
                                                                                               4
surprisingly, those who smoke are less, rather than more, likely to be treated (27-29).
Pharmacotherapy has the potential for the greatest absolute benefit and cost effectiveness in
these higher risk patients.


A healthy lifestyle improves cardiovascular risk and reduces blood pressure in the
prevention and treatment of hypertension. Healthy eating, regular physical activity, low
risk alcohol consumption, reductions in dietary sodium and in some, stress reduction (Table
8) can prevent or treat hypertension as well as other cardiovascular risks. However few
Canadians improve their lifestyle after being diagnosed with hypertension. Importantly brief
health care professional advice assists patients to make lifestyle changes (30). The Heart
and Stroke Foundation’s eHealth tool, My Heart&Stroke Blood Pressure Action Plan
(www.heartandstroke.ca/BP) is designed to assess hypertensive patients’ lifestyles, provide
personalized e-mail support and facilitate self-management through its interactive portal that
allows people to track their BP and progress and achievements in their selected lifestyle area
of focus. Several patient handouts on hypertension can also be obtained from
www.hypertension.ca/tools. Patients can also sign up for regular updates and information on
hypertension at www.myBPsite.ca

Treat to target (<140/90 mmHg; <130/80 mmHg in people with diabetes or chronic
kidney disease). CHEP blood pressure targets reflect current best evidence to optimally
reduce cardiovascular disease (Table 7). Failure to achieve blood pressure targets result in
higher cardiovascular risk while lowering blood pressure substantially below a target is of
undetermined benefit/harm. People with known cardiovascular disease, diabetes or chronic
kidney disease are at high cardiovascular risk, more often have uncontrolled blood pressure
and have the greatest reduction in cardiovascular events by achieving blood pressure targets
(27-29).

Reassess patients at least every two months if their blood pressure is above target.
Follow-up at short intervals improves patient adherence and is required to increase the
intensity of treatment.

Help patients adhere to therapy. Adherence to prescribed lifestyle change and
pharmacotherapy should be assessed at each visit. Health care professional interventions
can prevent non-adherence and improve adherence in those who are having problems (Table
9).


Comments from the CHEP executive
In 2010, CHEP will merge with the Canadian Hypertension Society and Blood Pressure
Canada to form a single national hypertension organization dedicated to advancing health by
the prevention and control of high blood pressure through research, advocacy, education and
knowledge development and translation. For Canadian health care professionals the
transition will likely be seamless and go unnoticed. Canadian educational material for health
care professionals and patients will carry the CHEP logo and name although the new
organization will be called Hypertension Canada.

CHEP recognizes the difficulties health care professionals and hypertensive Canadians have
in staying informed of the current best evidence in preventing and controlling high blood
pressure. In 2010 CHEP will help make staying up to date much easier. By enrolling at
                                                                                             5
www.htnupdate.ca you will be notified of all new hypertension resources produced by CHEP
for you or your patients. Further a new internet-based interactive lecture series will be
launched so you can be updated on important new hypertension topics by national leaders.
Also for those interested in being a community educator in hypertension, ‘train the trainer’
sessions have been developed and venues for training will be held across Canada. Sign up at
www.htnupdate.ca and stay informed.

2010 will also be an important year for determining Canada’s performance in prevention and
control of hypertension. Three major national surveys will report. On February 17, 2010, a
Statistics Canada survey will report the national prevalence of hypertension and the
awareness, treatment and treatment and control rate. Based on surrogate data from other
surveys, the national survey is anticipated to confirm the 2006 Ontario survey (ONBP) that
suggested Canada is the world’s leader in prevention and control of hypertension (31).
Further a detailed Statistics Canada - Public Health Agency of Canada survey of Canadians
with hypertension has been completed and will provide an overview of their knowledge,
attitudes, beliefs and behaviors. This information will be used to develop new educational
resources based on the documented educational needs of hypertensive Canadians. Finally
in 2010, the first federal provincial hypertension survey using linked provincial administrative
data bases will be released. This ongoing surveillance mechanism will track the incidence
and prevalence of diagnosed hypertension in people with and without diabetes and tracks
their mortality rates. CHEP continues to work with the Public Health Agency of Canada and
the provincial governments to develop the methodology to add assessment of
antihypertensive treatment and specific complications and causes of death to this latter
survey. The results of these surveys are critical to assess the impact of programs to prevent
and control hypertension and redesign interventions to be more effective.

Reducing dietary sodium will be a priority for Hypertension Canada. Canadians with
hypertension have little change in lifestyles after a diagnosis of hypertension. Although
individual lifestyle advice can assist Canadians make healthy choices often our communities
are structured to make healthy choices very difficult. Hypertension Canada strongly supports
the Health Canada Dietary Sodium Work Group mandate to reduce dietary sodium and
CHEP has aligned its dietary sodium recommendations to those of the Canadian
Government. The Health Canada Work Group has a mandate to reduce sodium additives to
food, to educate Canadians regarding the risks of high dietary sodium and to ensure research
required to reduce dietary sodium is conducted.

The CHEP executive would like to thank the over 100 health care professional volunteers,
who are working in CHEP to prevent and control hypertension. The collaborative approach
between volunteers from clinic practice, academia and governments with the support of the
primary care professional associations, the pharmaceutical health care industry,
governments, charities and scientific organizations has been associated with marked
improvements in the management and outcomes of hypertensive Canadians.

Table 4: Patient instructions to prepare for home blood pressure measurement
Purchasing Equipment

•   Buy an approved machine marked by the                     logo

•   Make sure the device has a cuff size that is correct for you. Ask for help if you are unsure.

To measure blood pressure -
• Follow the directions that come with the device.
• Only measure and record blood pressure if you have time to do it correctly.
• Do not measure blood pressure when you are uncomfortable, cold, anxious, stressed or in
   pain.
• Wait for at least two hours after heavy physical activity (e.g. long run) and at least half an
   hour after light physical activity (e.g. short walk), drinking coffee or smoking.
• Empty your bladder or bowels if uncomfortable before taking a reading.
• It is very important to rest and relax for 5 minutes in a quiet comfortable place with no
   distractions (e.g. TV or talking) before measuring your blood pressure.
• Put the cuff on a bare arm or one that has a thin sleeve
• Sit in a chair that supports your back and beside a table that can support your arm. If
   required put a pillow or towel under your arm so that it rests at heart level (see Figure).
   Do not cross your legs.
• Measure blood pressure in the morning before medications and eating and in the evening
   before going to bed, bathing or taking medications.
• Take at least two readings and record them with the date and time.

Table 6: Advice for People to Assist them to Reduce Dietary Sodium

DO
• Buy and eat more fresh foods especially fruit and vegetables
• Choose processed foods with low salt labels or brands with the lowest percentage of
   sodium on the food label
• Wash canned foods or other salty foods in water before eating or cooking
• If desired, use unsalted spices to make foods taste better
• Eat less food at restaurants and fast food outlets and ask for less salt to be added in your
   food orders
• Use less sauces on your food
• Eat foods with less than 200 mg of sodium or less than 10% of the daily value per serving

DON’T
• Buy or eat heavily salted foods (e.g. pickled foods, salted crackers or chips, processed
  meats, etc).
• Add salt in cooking and at the table
• Eat foods with more than 400 mg of sodium or more than 20% of the daily value per
  serving

Table 9: Strategies to Improve Patient Adherence*

1) Assist your patient to adhere
   i)      Tailoring pill-taking to fit patients’ daily habits
   ii)     Simplifying medication regimens to once-daily dosing

   iii)    replacing multiple pill antihypertensive combinations with single pill
           combinations
   iv)     Utilizing unit-of-use packaging (of several medications to be taken together)

   v)      Adherence to an antihypertensive prescription can be improved by a
           multidisciplinary team approach

2) Assist your patient in getting more involved in their treatment
   vi)     Encouraging greater patient responsibility/autonomy in monitoring their blood
           pressure and adjusting their prescriptions
   vii)    Educating patients and patients' families about their disease/treatment
           regimens

3) Improve your management in the office and beyond

   viii)   Assessing adherence to pharmacological and non-pharmacological therapy
           at every visit

   ix)     encouraging adherence with therapy by out-of-office contact (either by phone
           or mail), particularly during the first three months of therapy

   x)      Coordinating with work-site healthcare givers to improve monitoring of
           adherence with pharmacological and lifestyle modification prescriptions
   xi)     Utilizing electronic medication compliance aids
