The Almighty
Will drag me to hell and will not pardon
My ignorance of even the minute details of HT
My indifference to apply the current knowledge
My negligence in screening for HT, TOD
My despondency about preventing TOD
My inadequacy in maintaining my patients
as normo-tensive as possible –
(This is applicable to all common diseases)

Treatment of Hypertension
A CLINICAL APPROACH
Management of Hypertension
Based on the latest recommendations of
JNC VII, ISH, ESH, WHO

WHAT IS NEW IN HYPERTENSION?
www.drsarma.in
9
HYPERTENSION
What we record as B.P.
It is only a marker of the bigger problem
The Truth is
Hypertension is a multi-organ systemic disease
The Problem is
Hypertension is asymptomatic in 85% of cases
www.drsarma.in
10
How to be wise in HT?
It is wrong
To consider Hypertension as an isolated disease
The Truth is
Hypertension, DM, Dyslipidemia, Obesity often coexist
They are the 4 pallbearers to the grave of CHD, CVD
For all of them
Primary and secondary prevention by TLC is the answer
Afflicted with one, must be screened for all other thieves
www.drsarma.in
11
Treatment Goal
Goal BP
Keep B.P. < 140/90 mm Hg in each patient
This may be revised to 120/80 may be ? 110/70
MRFIT’s cut off values are 115/75 mm Hg
The Truth is
It is essential to keep the B.P at or below the goal
But, It also matters how the goal B.P. is achieved !

•
For every 800 adults in the community
400 are HT (either ↑ SBP or ↑ DBP or both)
Of them only 200 are diagnosed HT
Of them only 100 are started on treatment
Of them only 50 are on correct drug
Of them in only 25 the goal B.P. is attained
Means 25 ÷ 400 = 6% only have goal BP

Isolated Systolic Hypertension
1. What is ISH ? –
SBP 140+ , DBP < 90
2. What percentage of 65+ aged have ISH ?
More than 90%
3. Which is more harmful – ↑ SBP or DBP ?
Of course ↑ SBP
4. Why is ISH important ?
Because of ↑↑ CVA and CHD mortality

For adequate control of B.P.
Do you think we can control most of the
patients of hypertension with –
One drug
Two drugs
Three drugs
Can’t control
In most of the patients of hypertension
Two drugs are required for adequate control
More so if the initial BP is 20/10 above the goal

Paradigm Shift in HT Therapy
It is not just ↓B.P.
TODAY we must strive to
1. Alter the modifiable risk factors
2. Keep the SBP < 140 and DBP < 90
3. Prevent or halt or reduce TOD –
• LVH, CHD, CHF, CVA, CRF, PVD & Retino.
4. Prevent or control DM (as HT + DM is hazardous)
5. Prevent or control Dyslipidemia (Endothelial Dysf.)
6. Reduce morbidity and mortality
7. Improve QUALY – Quality Adjusted Life Years

What is MOST essential ??
Not that ‘my drug is superior to yours’
Not that ‘this trial is better than that’
Nor ‘this combination is better than that’
But to get AS MANY PEOPLE as we
can to goal SBP < 140 & DBP < 90
And prevent or halt TOD.
Of course, tailor the treatment as per
individual patient’s co-morbidities.
www.drsarma.in
65
Morbidity and Mortality in HT
Most of the morbidity and mortality of HT is due to
LVH – LV diastolic and systolic dysfunction
Increased risk of Coronary Artery Disease
Increased risk of Cerebral Vascular Disease
Hypertensive heart failure
Chronic Renal Disease of hypertension
Hypertensive vascular damage
www.drsarma.in
66
The correct Approach to HT
• Are all patients screened for hypertension?
Step1 • Are all hypertensives correctly identified?
• Are they evaluated for co-morbidities/TOD?
Step 2 • Are they assessed for CHD risk factors?
• Are the correct drug combinations prescribed?
Step 3 • What is the compliance for medicines & f/u?
• Is the goal B.P. achieved and maintained?
Step 4 • Are there any complications/ side effects?
www.drsarma.in
67
So, What is new in Hypertension ?
1. High B.P recorded is only a clinical marker disease
2. HT is a multi-organ disease, often asymptomatic
3. Not to consider in isolation- Must look for ‘Co-Thieves’
4. Today’s goal BP is 140/90 – It will sure be less tomorrow
5. It matters to attain goal; matters more how it is attained
6. In DM, CKD, IHD the cut off values are 10 mm less
7. Remember rule of ½ in HT– Adequate control only in 7%
www.drsarma.in
68
What is new in Hypertension - continued
8. ↑ SBP is more important than ↑ DBP; Often ignored it is !
9. Wide pulse pressure (SBP-DBP) signifies arterial damage
10. Day’s of monotherapy have gone; Combined Rx replaces
11. All HT must be screened for CHD risk factors & addressed
12. Target organ damage (TOD) must be investigated and Rx.
13. LVH is the single most predictor of mortality and morbidity
14. ABI, MAU, ABPM, PWV etc., identify high risk cases early

Lifestyle Modification
1. Life style modification is the sheet anchor
in the management Hypertension.
2. This surely reduces the number of drugs
used and their dosage in controlling HT.
3. Any drug treatment has value only when
coupled with Life style modification.

Many avoidable HT deaths !
On April 12, 1945, US President Franklin D. Roosevelt
died of cerebral hemorrhage, a consequence of HT. It
was a devastating illness for him.
By current standards, President Roosevelt’s death was
unnecessary. President Roosevelt was never treated
with Anti-hypertensive drugs.
Modern treatment would have controlled his BP and
prolonged his life.

Which drug should we prescribe ?
Choice must be tailored to individual
patient
Should be rational and as per approved
guidelines
Only class1 evidence based medications
to be used
Suitable to patients’ purse
Can never be arbitrary
www.drsarma.in
77
Physicians’ Bias in HT
Isolated SHT is often dubbed as ‘aging factor’
To consider HT is only in the ‘ARM’ and not in the body
No concept of ‘pulse pressure’ – Not seeing the whole
Worry about side effects – Need to watch, not to worry
OK, some control is achieved – why attain goal BP ?
Not insisting on compliance with drugs and assessments
Pressure from patients – B.P. How much ? How much ?
Concentrating on the pill and not on the ill – TLC forgotten

Hypertension – Why Combinations ?
If goal BP is not achieved by a single drug in full dose
Then adding another agent will help achieve the goal BP
Two agents sometimes nullify each others side effects
Fixed dose combinations will reduce the no. of tablets
Once daily formulations are good for compliance
Sustained release or LA formulations for 24 h BP control
If three drugs can’t achieve goal BP – Resistant HT

Hypertension – Rational Drug Combinations
ACEI and ARB = A
Diuretics = D – Rank 1
Beta Blockers = B
ACEI and ARB = A – Rank 2
Calcium Channel (CCB) = C
Beta Blockers = B – Rank 3
Diuretics Drugs= D
CCB = C – Rank 4
D and A combination is excellent -
Ramace H, Losar H, Enace D
D and B combination next -
Betaloc H, Atecard D, Tenoric
D and C combination sixth -
Amlogaurd H, Stamlo D
A and B combination Third -
Losar A, Cardif Beta
A and C combination fourth -
Amlopres L, Hipril A, Amlo LS
B and C combination fifth -
Amlo AT, Amlobet, Beta Nicardia
www.drsarma.in
86
Some Irrational Combinations
Beta blockers + Beta1 stimulants - Rebound HT, Paradoxical BP ↑
Beta blockers + Vepapamil -
Extreme bradycardia, HB, CHF
Thiazide + Furesemide
Potential volume ↓ and K ↓
CCB + Thiazide
-
-
No RCTs to support the additive
Prazocin + Beta blocker -
They nullify the effects of each other
Verapamil / Dilzem + Nefidepine -
No rationale (cardiac actions contridic)
Beta blocker + ACEI
Not for HT alone, Good for CHF, MI, IHD
Sub clinical doses of two drugs
Try one drug in good dosage, then add
Two drugs of same class -
No rationale (like Enalapril + Ramipril)
(Atenelol + Metoprolol, Nefidepine + Amlo)

Hypertension and cough
Hypertensives may present with cough – watch out
1. Consider LVF as the cause of cough
2. Consider ACEI induced dry cough
3. Stop ACEI and give ARB or other agents
4. Check the composition of the cough remedy you give
5. Ephedrine, Pseudephedrine, should be avoided
6. Oral Beta agonists like Orciprenaline, Salbutamol,
Terbutaline the less used, the better.
7. Inhaled beta agonists, ICS are safe
8. Decongestants like phenyl propanolamine to be avoided

Case 25
Secondary Hypertension – various causes
Secondary HT
Treatment
Absolute contra
www.drsarma.in
Usually Stage 2 - HT
Secondary causes will be present
May present in young individuals
Look for secondary cause and treat
Life style interventions must
Vigorous efforts required to control HT
Often two or even 3 drugs may be required
Resistant HT may be encountered
Anti HT drugs as per secondary cause
ACEI or ARB in bilateral renal artery stenosis
124
Case 26
Secondary Hypertension in Pheochromocytoma
Pheochromocytoma Usually Stage 2 HT, Episodic or Labile
Secondary adrenal medullay tumor
May present in young individuals
Treatment
Surgical Ablation of the chromaffin tissue
HT needs to be controlled before surgery
Alpha blockers are the drugs of choice
Phentolamine, Phenoxybenzamine, Prazocin
Vigorous efforts required to control HT
Often two or even 3 drugs may be required
Resistant HT may be encountered
Surgery
First reduce HT, then surgery
Do not use

Beta blockers
125
Case 27
Resistant HT
Reasons
Rationale
www.drsarma.in
Resistant Hypertension
Usually Stage 2 HT
May present in young individuals
May have secondary causes
Not taking medication (liers)
Improper BP measurement
Excessive Na intake, Inadequate diuretic Rx.
Full doses of drugs not employed
Drug interactions – NSAIDs, SMA, OCP, OTC
Herbal remedies, Excessive alcohol use
Identify the above and correct
Secondary causes to be searched for

Case 30
Hypertensive with Acute CVA (Stoke)
HT + CVA (Stroke)
Rationale
Treatment
www.drsarma.in
Marked DBP elevation
May be SAH, ICH, Acute Brain Infarction
In acute setting, no consensus on
treatment of elevated BP
HT at time of an acute stroke associated
with increased risk of cerebral hemorrhage
and edema, increased mortality
After acute ischemic stroke, cerebral
auto regulation affected
Active treatment of BP in the first 7 days
could worsen symptoms
Recommendation not to start HT Rx.
before 7 to 10 days after ischemic stroke
128
Current Indications for Alpha Blockers
1. Hypertension with BPH
2. In Pheochromoytoma before surgery
3. In the treatment of Ergot over dose
4. Raynaud’s syndrome and PVD, TAO
5. Vasospastic (prinzemetal Angina)
6. Diabetic neuropathy
7. Hypertensive smokers
8. Hypertension with Dyslipidemia
First dose syncope and Postural Hypotension
