The clinical
differentiation between hypertensive emergency and acute severe hypertension is
dependent on the presence of target organ damage (TOD) rather than the level of
blood pressure (BP), as stated in the Introduction
section.
It is estimated that
approximately 1-2% of individuals with hypertension will experience a
hypertensive crisis as a result of untreated or inadequately controlled blood
pressure. A detailed discussion about the prevalence of hypertensive crisis is
in the Epidemiology section.
The Pathophysiology section
states that chronic uncontrolled hypertension causes long-term endothelial
injury characterized by oxidative stress and reduced nitric oxide production. The development process of hypertensive
emergencies in patients is in this section.
The Risk Factors section
explains the conditions that may contribute to the development of hypertensive
crisis.
Hypertensive Crisis_Disease SummaryHistory and Physical Examination
The Clinical
Presentation section
describes the clinical features that may be present in patients evaluated for
hypertensive crisis.
The History section discusses the different information
needed in the assessment of patients with acute severe hypertension while the Physical Examination
section explains the importance of a proper blood pressure
measurement and other related examinations.
Chẩn đoán
Discussions on blood
examinations such as complete blood count (CBC), creatinine, electrolytes and
other tests in the evaluation of hypertensive crisis are in the Laboratory Tests and Ancillaries
section.
The Imaging section lists diagnostic tests
such as 12-lead electrocardiogram (ECG), chest X-ray, computed tomography (CT) and
ultrasounds that may be done in patients suspected of hypertensive crisis.
Underlying conditions that can either trigger
or occur alongside hypertension-induced organ dysfunction in hypertensive
crisis are listed in the Differential
Diagnosis section.
Xử trí
General therapy principles and treatment goals
in hypertensive crisis are in the Principles
of Therapy section.
The Pharmacological
Therapy section discusses in
detail the preferred antihypertensive agents depending on the type of
hypertensive emergencies and acute severe hypertension.
