I am a gentle killer
All over the world, I am called HYPERTENSION
World Hypertension Day, annually celebrated on May 17th
Statement of Need Please write down your answer to the following:
“My greatest challenge as a doctor in the management of patients with hypertension is……………” When to begin treatment, How low to aim for, and Which antihypertensive medications to use.

JNC 7 Compelling Indications
† ACEI, angiotensin converting enzyme inhibitor; ARB, angiotensin receptor blocker;Aldo ANT, aldosterone antagonist; BB, beta-blocker; CCB, calcium channel blocker.
Compelling Indicator: Heart Failure ACE-I (or ARB) is indicated in nearly all patients with LV systolic dysfunction. ACE-I (or ARB) should be titrated to target HF doses, even if BP is low, as long as the patient does not become symptomatic or develop impaired renal perfusion.
Beta Blockers in nearly all patients with LV systolic dysfunction .Titrate to target HF doses.
Consider spironolactone after the patient is placed on the maximum doses of ACE-I and beta-blocker,especially if Class III or IV
Diuretics (usually loop) are often required for fluid management
Compelling Indicator : Chronic Kidney Disease ACE-I and ARB’s can slow progression of kidney disease. AA limited limited increase increase in in serum serum creatinine creatinine of of as as much much as as 30% 30% above above baseline baseline with with ACE-I ACE-I or or ARB ARB isis acceptable acceptable and and not not aa reason reason to to withhold withhold treatment, treatment, unless unless hyperkalemia hyperkalemia develops. develops.

Questions guiding the JNC 8 review This hypertension guideline focuses on 3 questions related to high blood pressure (BP) management. They address thresholds, goals for pharmacologic treatment, and whether particular antihypertensive drugs or drug classes improve important health outcomes compared to others.
1.In adults with hypertension, does initiating antihypertensive pharmacologic therapy at specific BP thresholds improve health outcomes? 2.In adults with hypertension, does treatment with antihypertensive pharmacologic therapy to a specified BP goal lead to improvements in health outcomes? 3.In adults with hypertension, do various antihypertensive drugs or drug classes differ in comparative benefits and harms on specific health outcomes? The answers to these three questions are reflected in 9 recommendations

JNC 8 :Relaxing blood pressure goals
Higher real-world blood pressures This is akin to the “speed limit rule”— people are more likely to hover above target,no matter what the target is.
Recommendation in patients with grade I hypertension (BP 140–159 mm Hg systolic or 90–99 mm Hg diastolic)
ESH/ESC BP-lowering drugs recommended when total cardiovascular risk is high because of organ damage, diabetes, cardiovascular disease, or chronic kidney disease JNC 8 BP-lowering drugs recommended to lower BP <140 mm Hg systolic and 90 mm Hg diastolic in patients aged <60 years ,and <150 mm Hg systolic and 90 mm Hg diastolic in patients aged >60 years
