Hypertensive crisis is defined as a severe increase in blood pressure that requires prompt treatment to prevent end organ damage. There are two categories: hypertensive urgency, where blood pressure is elevated but there is no acute organ damage; and hypertensive emergency, where elevated blood pressure is associated with acute organ damage. Patients with hypertensive urgency can be treated orally to lower blood pressure by 25% over 24 hours, while those with emergency require rapid intravenous treatment to lower it by 10-25% within minutes to hours. Rapid reduction of blood pressure should be avoided to prevent ischemic events.

Hypertensive Crisis
This document discusses hypertensive crises, including definitions, epidemiology, pathophysiology, assessment, diagnosis, and management. It defines hypertensive emergencies as elevated blood pressure with acute end-organ damage, while hypertensive urgencies involve impending end-organ damage. The typical patient presenting with crisis is middle-aged, noncompliant with medications, and may use substances. Treatment of emergencies requires immediate blood pressure reduction in the ICU to prevent further damage, while urgencies can be treated gradually as uncontrolled hypertension. Nitroprusside is very effective but has limitations like toxicity risks with prolonged use.
Hypertensive emergencies
- Hypertensive emergencies are severe hypertension with acute end-organ damage. Common causes include essential hypertension, preeclampsia, renal disease, pheochromocytoma.
- The brain, heart, kidneys are most vulnerable to damage. Symptoms include headache, confusion, chest pain, dyspnea.
- Treatment involves rapid blood pressure reduction, usually over hours, to prevent further injury. Antihypertensives like nicardipine, labetalol, nitroprusside are used. Blood pressure goals depend on specific end-organ involved.
- Stroke requires more cautious reduction to avoid worsening ischemia or hemorrhage. Heart failure is treated with diuretics

1) Hypertensive crisis is defined as a sudden rise in blood pressure that causes end organ damage and is classified as either a hypertensive urgency or emergency.
2) Common causes include poorly controlled essential hypertension and renal disease.
3) Rapid evaluation is needed to identify end organ damage to the heart, kidneys, brain, or vasculature.
4) Treatment involves slowing lowering blood pressure, usually over hours
Hypertensive crisis
Hypertensive crisis is defined as a systolic blood pressure over 180 mmHg and/or diastolic blood pressure over 120 mmHg that can lead to end organ damage. It is classified as either a hypertensive emergency, requiring immediate medical treatment to prevent permanent organ damage, or a hypertensive urgency where treatment is still needed but not as immediately. Common causes of hypertensive crisis include uncontrolled essential hypertension, pregnancy-related conditions like preeclampsia, renal disease, endocrine disorders, drug or substance use, and neurological issues.
HYPERTENSIVE EMERGENCY
Severe hypertension that is a potentially life-threatening condition refers to a hypertensive crisis.
Severe hypertension is further classified into hypertensive emergencies or hypertensive urgencies.
Hypertensive emergency refers to a severe hypertension that is associated with new or progressive end-organ damage. In these clinical situations, blood pressure should be reduced immediately to prevent or minimize organ dysfunction.
Hypertensive urgency refers to severe hypertension without evidence of new or worsening end-organ injury.
A hypertensive emergency is hypertension with acute impairment of one or more
organ systems that can result in irreversible organ damage. Especially:-
Central nervous system
Cardiovascular system
Renal system.
The term hypertensive emergency is primarily used as a specific term for a hypertensive crisis with a diastolic blood pressure greater than or equal to 120mmHg and/or systolic blood pressure greater than or equal to 180mmHg.
Hypertensive emergency differs from hypertensive crisis in that, in the former, there is evidence of acute organ damage.

The goals are to gradually lower blood pressure by 10-20% in the first hour and further 5-15% over 24 hours, to a target of <180/<120 mmHg initially and <160/<110 mmHg thereafter. Management depends on the specific end organ involved and may require additional interventions like thrombolysis. Close follow up is needed after discharge to prevent recurrence through treatment of underlying causes and management of blood pressure long term.
Hypertensive Crisis.pptx
This document discusses the evaluation, diagnosis, and management of severe hypertension. It defines different types of severe hypertension including hypertensive urgency, hypertensive emergency, resistant hypertension, and refractory hypertension. It provides details on clinical presentation, diagnostic tests, rate of blood pressure reduction, outpatient versus inpatient management, and intravenous antihypertensive medications. The goal is to lower blood pressure slowly over hours to days to reduce risks of end-organ damage while also addressing any underlying causes of treatment-resistant hypertension.
Sasi hypertensive emergensies
This document discusses hypertensive emergencies and urgencies. It defines hypertensive emergency as severe hypertension with acute end-organ damage, requiring rapid BP reduction over hours. Hypertensive urgency is severe hypertension without acute end-organ damage, allowing BP control over days to weeks. The main organs affected are the brain, heart, and kidneys. Initial treatment involves evaluating for end-organ damage and relaxing the patient before considering IV antihypertensives. Goals are to lower BP by 25% over the first hour while maintaining organ perfusion. Specific treatments depend on the damaged organ system. Follow-up after discharge assesses for ongoing hypertension management.
Hypertension pathophysiology
Hypertension is defined as high blood pressure with a systolic reading of 140 mmHg or higher or a diastolic reading of 90 mmHg or higher. It can be caused by primary or secondary factors. Primary hypertension makes up 90-95% of cases and has contributing lifestyle factors like increased sodium intake, obesity, lack of exercise, and excessive alcohol consumption. Secondary hypertension is caused by an underlying medical condition. Treatment involves lifestyle modifications like diet, exercise, weight loss and lowering sodium intake as well as medication to control blood pressure. The goal of treatment is to reduce cardiovascular risk by maintaining a blood pressure reading under 140/90 mmHg or under 130/80 mmHg for those with diabetes or kidney disease.
MANAGEMENT OF HTN AND T2DM IN ACUTE STROKE in stroke
This document discusses hypertension and its relationship to stroke. Some key points:
1. Hypertension is the leading modifiable risk factor for both ischemic and hemorrhagic stroke. Appropriate blood pressure control can reduce stroke risk and recurrence.
2. For acute ischemic stroke, blood pressure should be carefully lowered if considering thrombolysis to below 185/110 mmHg. Otherwise, moderate hypertension may be permitted in the first 24 hours.
3. For intracerebral hemorrhage, blood pressure needs to be controlled immediately and aggressively lowered to 140 mmHg or below to reduce hematoma expansion and improve outcomes.

Hypertension, also known as high blood pressure, is when blood pressure levels are consistently higher than normal. It is classified into stages based on systolic and diastolic blood pressure readings. The most common type is primary hypertension, while secondary hypertension has an identifiable underlying cause. Risk factors include age, family history, diet, lifestyle and certain medical conditions. Uncontrolled high blood pressure can damage vital organs and lead to health issues like heart attack or stroke over time. Treatment involves lifestyle modifications and medications to control blood pressure and prevent complications.

This document provides guidance on managing patients with hypertension. It begins with 3 practice questions on hypertension management goals and treatment options. The main points covered include defining hypertension and its importance, diagnostic criteria requiring multiple measurements, classification of primary vs secondary hypertension, lifestyle modifications and drug treatment options. Target blood pressure is outlined as <130/80 mmHg with considerations for elderly patients. First-line drug options include thiazide diuretics, calcium channel blockers, ACE inhibitors and ARBs. Combination therapy may be needed to control high blood pressure.

Management of hypertension in acute stroke
Hypertension is an important and common risk factor for brain stroke- both ischemia and hemorrhagic subtypes. Appropriate management of blood pressure is crucial for good recovery rom acute stroke, and prevent recurrence of stroke. This presentation looks at the role played by hypertension in causing first ever and recurrent strokes. The current guidelines are also discussed.
HTN E & U(1) (1).pptx
Hypertension emergency is characterized by severely elevated blood pressure (>180/120 mm Hg) and evidence of impending organ damage. Hypertension urgency also involves severely elevated blood pressure but without organ damage. The goal of treatment is to gradually lower blood pressure over minutes to hours in emergencies and over 24 hours in urgencies to prevent organ damage. Intravenous drugs are used for emergencies while oral drugs are preferred for urgencies with close monitoring. Specific treatment depends on the underlying cause and affected organs.
Hypertensionbbvghhvvhbbvvgbbbvvbbvv.pptx
1. Hypertension is defined as blood pressure above 140/90 mmHg with no secondary cause identified. Cardiovascular risk increases as blood pressure rises, especially systolic pressure over age 50.
2. Secondary hypertension may be suspected in patients who develop hypertension at a young or old age, have abrupt onset, end organ damage disproportionate to blood pressure levels, or treatment resistance. Common causes include primary aldosteronism and obstructive sleep apnea.
3. Diagnostic tests aim to identify secondary causes and end organ damage. Treatment involves lifestyle modifications and antihypertensive medications, starting with a diuretic. Resistant hypertension requires evaluating adherence and identifying secondary causes. Hypertensive emerg
Hypertension Emergencies and their managementpptx
This Presentation talks about Hyprtension, the mode of presentation of hypertensive crisis and the effective management of hypertensive crisis to prevent case fatalities.
hypertensive crisis.pptx
A hypertensive crisis is a sudden spike in blood pressure to 180/120 mmHg or higher, which is a medical emergency that could lead to organ damage or be life-threatening. Symptoms include headaches, confusion, chest pain, nausea, and weakness. Causes include non-compliance with medications, high salt/fat diets, certain drugs, kidney disease, and hormone imbalances. Treatment involves reducing blood pressure in the ICU over hours to days depending on any organ damage present. Nursing care focuses on monitoring, medication administration, lifestyle changes, and education to prevent future crises.
About Hypertension & it's management
Hypertension is defined as high blood pressure with a systolic reading over 140 mmHg or diastolic over 90 mmHg. It can be caused by many factors like increased cardiac output, vasoconstriction, fluid volume, and activation of the renin-angiotensin system. Treatment involves lifestyle modifications like weight loss, reduced sodium intake, and exercise as well as drug therapy using diuretics, ACE inhibitors, calcium channel blockers, and beta blockers. Uncontrolled hypertension can damage organs and lead to complications like heart disease, stroke, and kidney disease so treatment aims to control blood pressure and reduce cardiovascular risk.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

Hypertensive crisis
- 1. Hypertensive Crisis Dr Mohamad Amirul Ain Hospital Pontian
- 2. Definition • Hypertension is defined as persistent elevation of systolic blood pressure (BP) of 140 mmHg or greater and/or diastolic BP of 90 mmHg or greater, taken at least twice on two separate occasions. • Severe hypertension is defined as persistent elevated SBP >180 mmHg and/or DBP >110 mmHg.
- 3. These patients may present with: • incidental finding in an asymptomatic non-previously diagnosed patient • treated hypertension on follow-up who are asymptomatic • patients with symptoms which may include: » non-specificsymptomslikeheadache,dizziness,lethargy » symptoms and signs of acute target organ damage/complication. • Patients are then categorised as having: a. hypertensive urgencies (urgency), or b.hypertensive emergencies (emergency)
- 5. Hypertensive urgency • Hypertensive urgency is defined as severe increase in BP which is not associated with acute end organ damage/complication and these include patients with grade III or IV retinal changes (also known as accelerated and malignant hypertension), but no overt symptoms and signs of acute target organ damage/complication. • Blood pressure measurement should be repeated after 30 minutes of bed rest.Initial treatment should aim for about 25% reduction in BP over 24 hours but not lower than 160/100 mmHg. • Oral drugs proven to be effective. Combination therapy may be necessary. • Importantly, there is no role for intravenous BP lowering drugs. • Many of these patients have withdrawn from or are not adhering to antihypertensive therapy and do not have clinical or laboratory evidence of acute target organ damage.Possible precipitating factors for hypertensive urgency include non- adherence to anti-hypertensive medications, less effective outpatient blood pressure control, acute pain, herbal supplement and emotional stress.
- 8. Hypertensive emergency • Hypertensive emergency is defined as severe elevation of blood pressure associated with new or progressive end organ damage/complication such as acute heart failure, dissecting aneurysm, acute coronary syndromes, hypertensive encephalopathy, acute renal failure, subarachnoid haemorrhage and/or intracranial haemorrhage. These may occur in patients with BP <180/110 mmHg, particularly if the BP has risen rapidly.
- 9. • These patients: • should be admitted for immediate intervention and monitoring. • need to be reduce their BP rapidly based on clinical scenarios • should have their BP reduced by 10%-25% within certain minutes to hours but not lower than 160/90 mmHg • This is best achieved with parenteral drugs.
- 17. Danger of rapid reduction in blood pressure • Rapid reduction of BP (within minutes to hours) in hypertensive urgencies should be avoided as it may precipitate ischaemic events. • Oral or sublingual drugs with rapid onset of action can result in an uncontrolled BP reduction. Several serious side effects have been reported with the administration of sublingual fast-acting nifedipine and therefore this is no longer recommended.However oral nifedipine retard can be used and has been recommended as first line therapy for hypertensive urgencies. • Following stabilisation of patient’s BP, subsequent management is tailored towards achieving optimal control.
