Hypertension is the most prevalent CV disorder in the world and according to the WHO, it affects 1.28 billion adults aged 30–79 years worldwide, two-thirds living in low-income and middle-income countries.
In 2019, the global age-standardized average prevalence of hypertension in adults aged 30–79 years was reported to be 34% in men and 32% in women.
At younger ages (<50 years), hypertension is more prevalent in men, whereas a steeper increase of SBP in women from their third decade (and more so following menopause) makes the prevalence of hypertension greater in women in older age categories (>65 years).
Rule of Halves
Half the people with high blood pressure are not known (“rule 1”),
Half of those known are not treated (“rule 2”) and
Half of those treated are not controlled (“rule 3”)'
Definition:
Hypertension is defined based on repeated office SBP values ≥ 140 mmHg and/or DBP ≥ 90 mmHg.

worldwide, two-thirds living in low-income and middle-income
countries.
• In 2019, the global age-standardized average prevalence of
hypertension in adults aged 30–79 years was reported to be 34% in
men and 32% in women.
• At younger ages (<50 years), hypertension is more prevalent in men,
whereas a steeper increase of SBP in women from their third decade

(b) Use of Diuretics:
I. Use T/TL Diuretic if eGFR >45 ml/min/1.73 m2.

between 30 to 45 ml/min/1.73 m2.

32. Key Points
1. In most patients, treatment should be initiated with an SPC of two
drugs to improve the speed, efficiency and predictability of BP control.
2. Although several two-drug combinations can be used, the preferred
two-drug combinations should be an RAS blocker with a CCB or a
Thiazide/Thiazide-like diuretic.
3. A BB can be used at any step of combination with any drug from the
other major drug classes as GDMT or in several other conditions but no
longer a first line hypertensive drug.

33. Key Points
4. Initial monotherapy is recommended for very-high-risk patients with
a high-normal BP as well as (for cautionary reasons) for very old and
frail patients. It may also be considered in low-risk patients with stage 1
hypertension whose SBP is more modestly elevated (<150 mmHg).
5. A combination of two antihypertensive agents and a statin at low
doses reduced the risk of CV outcomes by 38%.
6. >80% of the patient adhere to combination therapy.
