How can hypertension be diagnosed?
A blood pressure reading measures the pressure in the arteries when the heartbeats (top number, called systolic pressure) and between heartbeats (bottom number, called diastolic pressure).1
What is the classification of office blood pressure and the definition of hypertension grades?
Adapted from Ref.3
The BP category is defined by the highest level of BP, whether systolic or diastolic.
a Isolated systolic or diastolic hypertension is graded 1, 2 or 3 according to SBP and DBP values in the ranges indicated. The same classification is used for adolescents ≥16 years old.
What are the complications of hypertension?
Persistently elevated blood pressure and hypertension lead to hypertension-mediated organ damage and cardiovascular disease.2

High Blood Pressure, High Risk: How Hypertension Fuels Heart Failure
Hypertensive heart disease can happen if you have unmanaged high blood pressure for a long time. The added strain on your heart could lead to heart failure or other health problems9

Diagnostic Work-up

Pathophysiology
Adapted reference 10
In the most widely accepted model of hypertensive heart failure, chronic pressure overload leads to the development of left ventricular hypertrophy (LVH). Progressive hypertrophy and fibrotic changes in the heart lead to progressive diastolic dysfunction ultimately leading to elevated left sided filling pressures and diastolic heart failure. Eventually, a subset of patients progresses to systolic dysfunction in the presence of chronic volume and pressure overload.12

Understanding the Hypertension–Chronic Kidney Disease Axis
CKD and high blood pressure are closely tied together. Either condition can lead to or worsen the other13
Adapted from Ref.14
Schematic representation of factors involved in kidney damage, hypertension and end-stage renal disease (ESRD). Figure shows complications arise upon activation of the renin-angiotensin system (RAS) secondary to kidney damage. Increased RAS activity subsequently activates angiotensin-
1 receptor (AT1 receptors) via increasing angiotensin II (Ang II) and decreases glomerular filtration rate (GFR). Angiotensin 1 receptor activation results in amyriad of effects such as vascular remodeling and inflammation, aldosterone release, sodium/H2Oretention, disturbs the balance between antioxidant (superoxide dismutase; SOD) and oxidant (nicotine amide dinucleotide phosphate; NADPH) mechanisms14
PREVENTION & MANAGEMENT
The good news is that there is a lot to do to prevent or manage both CKD and high blood pressure13

Hypertension and Myocardial Infarction: Understanding the Connection
Systemic hypertension is the most prevalent cardiovascular risk factor resulting in premature death15
Prevalence of hypertension is reportedly 30%‐40% among patients with an ST‐elevation myocardial infarction (STEMI) and rises up to 70% in patients with a non–ST‐elevation myocardial infarction (NSTEMI).16
Pathophysiological factors that link hypertension with acute coronary syndromes.16
ACE, angiotensin‐converting enzyme; ACS, acute coronary syndrome; Ang II, angiotensin II; BKB2, bradykinin B2; KCNMA1, Ca++‐dependent potassium channel alpha1 subunit; LVH, left ventricular hypertrophy; NO, nitric oxide
By adopting a heart-healthy lifestyle, patient can17:
- Reduce blood pressure.
- Prevent or delay the development of high blood pressure.
- Improve how well blood pressure medications work.
- Lower risk of high blood glucose (blood sugar) and high cholesterol.
- Lower risk of heart attack, stroke, heart failure, kidney damage
- Lower risk of dementia
