Why Should We be Interested in Hypertension?
1.High prevalence of HTN & preHTN & poor control
2.Lacking Public and professional awareness
3.Open market for all possible drugs
4.Public misconceptions Re HTN, Rx & herbs
5.Many professionals “schools” with diverse traditions
6.HTN not adequately recognized as life-long risk for
CRF, Stroke and MI

Aims of Clinical Evaluation
Accurate Measurement of BP to establish
the diagnosis of Hypertension.
Look for other risk factors.
Assess for Co morbidities.
Look for Target Organ Damage or
associated clinical conditions.
Be alert for clues of secondary cause.
– Thorough history, physical exam & simple
tests.

think of Coarctation, dissection. FU visit check BP
in the higher arm.

Laboratory tests
26

Management Plan
Establish Good patient Doctor relationship.
Educate patient & family on the consequences of
hypertension.
Encourage Self monitoring.
BP goal.
Non pharmacological therapy.
Pharmacological therapy.
29
Life Style Modification
Stop smoking.
Lose weight if overweight.
No alcohol intake.
Reduce sodium intake to 110 mmol/day (2.4 g
sodium or 6 g sodium chloride).
Maintain adequate dietary potassium, calcium, and
magnesium intake.
Healthy diet; High in fresh fruits, vegetables and low fat
dairy products, low in saturated fat.
Regular physical activity: optimum 30-45 minutes of
moderate cardiorespiratory activity 3-5/week or more 30

Statins
PRIMARY PREVENTION
1) Total cholesterol > 5 mmol/l,
2) < 70 Y., and
3) 10 Y. CHD-R > 30%.
SECONDARY PREVENTION
1) Total cholesterol > 5 mmol/l,
2) < 75 Y., and
3) CV complication: – (Coronary Heart Diseases, Peripheral Vascular Diseases, Non-
hemorrhagic CerebroVascular Diseases, or Atherosclerotic
renovascular diseases.)
36
Antiplatelet Therapy
only when BP control has been achieved
For Primary Prevention:
Hypertensive patients above the age of 50 years
and at high or very high absolute cardiovascular
risk, or
Hypertensive patients with moderate increase in
serum creatinine > 1.3 mg/dl i.e. > 107 mmol/L.
For Secondary Prevention:
Patients with post MI, ischemic stroke,
angioplasty, or coronary bypass
37
When you need to question
compliance
When the treatment response is judged inadequate,
the patient can be asked about compliance. If
the patient reports less than complete compliance, the
clinician can proceed with compliance interventions.
If the patient reports full compliance, problems with
the treatment itself can be considered along with
application of more sophisticated methods of measuring
compliance.
38
Forms of Non-compliance
Not
having the prescription filled,
Taking the incorrect dose,
Taking the medication at the wrong
time,
Not taking one or more doses,
Stopping the medication too soon,
Relying on herbal meds
39
How/Can we measure?
1• Pharmacological measures ( concentrations of
drugs or using biological markers integrated into
the tablets) (difficult)
2• Clinical measures: a) evaluation of promptness
for appointments or b) the use of questionnaires
c) or taking the amount of side effects into
account)
3• Physical measures ( pill counting )
40
Recommendations for Improving compliance
using a multi-faceted approach
Understanding the reasons for these forms of non-compliance is of key importance
to the successful development of potential programs and their implementation
- Simplify medication regimens to once daily dosing
– Tailor pill-taking to fit patients’ daily habits
– Encourage greater patient responsibility/autonomy in monitoring their BP management
(including monitoring)
– Coordinate with worksite health care givers to improve monitoring of adherence with
pharmacological and lifestyle modification prescriptions
– Educate patients and educate/involve patients’ families about their disease/treatment
regimens
– Minimize side-effects, make taking it more appealing
High standard educated and motivated health care providers,
41
Indications for specialist
referral
1.Urgent treatment needed
2.Possible underlying cause
3.Therapeutic problems
4.Special situations
Other Indications
42
Hypertension &Ramadan
“Based on the scarce available data, the
following recommendations can be reasonably
made”
medical advice before fasting in order to adjust their medications, if
needed.
management should be individualized in fasting patients.
emphasize compliance with non-pharmacological and
pharmacological measures.
Diuretics are better avoided, especially in hot climates or to be
administered in the early evening.
emergency should be treated appropriately regardless of fasting.
Many questions are awaiting answers.
43
Hypertension in the Elderly
Hypertension occurs in more than half of
individuals aged 65 are HTN & poor control
Follow same Rx principles outlined for the general
care of hypertension
Lower initial drug doses may be indicated to avoid
symptoms
Standard doses and multiple drugs are needed in
the majority of older people to reach appropriate
BP targets
44
Hypertension in Pregnancy
Chronic hypertension
Preeclampsia-eclampsia: preeclampsia occur in 23%; and eclampsia in 5-6/10,000 pregnancies that
progress beyond 20 weeks.
Preeclampsia Superimposed upon chronic
hypertension or Renal Disease
Gestational hypertension (only during pregnancy):
occur in 8-10% of nulliparous women
Transient hypertension (only after pregnancy)
45
Treatment during pregnancy
Shared care with obstetrician for proper evaluation
Lifestyle changes: restrict activity and exercise during
pregnancy.
Weight reduction is not recommended.
Limit Sodium intake.
Methyldopa and ß-blockers can be used. Be ware of
the possible growth restriction
An alternative would be nifedipine
Diuretic are not usually used in pregnancy
ACEI and ARBare contraindicated. If a patient becomes
pregnant while on these agents, she should have her
medication changed.
The “cure” for preeclampsia is delivery
46
Anticonvulsive Therapy
Breast Feeding
All antihypertensives studied have been found in breast milk.
Long-term neonatal effects have not been studied.
Methyldopa as a first-line oral agent is reasonable unless
contraindicated, and then labetolol may become first-line therapy.
If the patient has renal disease, then calcium channel blockers are
the drugs of choice.
ACE inhibitors and angiotensin II receptor antagonists should not
be used due to neonatal renal effects.
Diuretics may decrease milk production.
Certain beta blockers are concentrated in breast milk (atenolol
and metoprolol), while others are not (labetolol and propranolol).
47
Hypertension and the Pill
Oral contraception usually shifts the blood pressure
moderately upwards, but hypertension appears in
less than 5% of women (1% to 2%).
Stopping OC is an effective antihypertensive
intervention in a clinical setting.
keeping careful check on women taking these pills.
