High Blood Pressure: When Hospitalization Is Necessary

High blood pressure, also known as hypertension, is a common condition that affects nearly 50% of American adults. While it often goes unnoticed, it can lead to serious health issues such as heart attacks and strokes. Hypertension can sometimes progress to a hypertensive emergency, requiring immediate hospitalization. This occurs when blood pressure readings surge to 180/120 mm Hg or higher, and it can cause organ damage or failure, increasing the risk of stroke and heart failure. Even without prior hypertension, a hypertensive crisis can be life-threatening and demands immediate medical attention. Symptoms such as chest pain, light-headedness, or shortness of breath alongside high blood pressure readings warrant urgent treatment and possible hospitalization.

Hypertensive crisis: when blood pressure rises to 180/120 mm Hg or higher

A hypertensive crisis is a severe medical condition that requires immediate attention. It occurs when an individual's blood pressure surges to 180/120 mm Hg or higher without warning. This is classified as a hypertensive emergency, which indicates extremely high blood pressure that can lead to life-threatening complications.

During a hypertensive crisis, immediate medical attention is crucial. If you or someone you know is experiencing this, call 911 or your local emergency services without delay. This sudden spike in blood pressure can lead to dangerous issues affecting the heart, lungs, or brain if left untreated. Therefore, it is essential to seek professional help right away.

The symptoms of a hypertensive crisis may include chest pain, dizziness, or a severe headache. It is considered an emergency, especially when accompanied by symptoms like light-headedness, indicating a potential risk of stroke or other fatal complications. Healthcare providers will work to reduce blood pressure immediately in hypertensive emergency cases.

In addition to seeking emergency care, individuals experiencing a hypertensive crisis should follow up with their regular healthcare provider after receiving initial treatment. Healthcare providers may adjust medications and recommend lifestyle changes, such as dietary modifications or increased physical activity, to help manage blood pressure and prevent future crises.

It is important to note that hypertensive crises can occur even without a history of hypertension. Therefore, it is crucial to monitor your blood pressure regularly and be vigilant about seeking medical attention if your blood pressure reaches concerning levels. Additionally, maintaining good control over your blood pressure through maintenance measures is essential to prevent hypertensive crises and their potentially severe consequences.

Hypertensive emergency: very high blood pressure causing organ damage

A hypertensive crisis is a medical emergency that requires immediate attention. It occurs when an individual's blood pressure suddenly surges to 180/120 mm Hg or higher. While most people who experience a hypertensive crisis have high blood pressure or hypertension, it can also affect those without a history of blood pressure issues.

During a hypertensive crisis, individuals may experience symptoms such as chest pain, dizziness, severe headaches, nosebleeds, or light-headedness. These symptoms, coupled with high blood pressure, can indicate a hypertensive emergency, which is characterised by new or worsening organ damage.

Hypertensive emergencies specifically refer to cases where extremely high blood pressure leads to acute organ dysfunction. The affected organs may include the heart, aorta, eyes, brain, and kidneys. Examples of acute organ dysfunction include acute pulmonary edema, cardiac ischemia, neurologic emergencies, aortic dissection, acute renal failure, and eclampsia.

The treatment for hypertensive emergencies focuses on rapidly lowering blood pressure within the first few hours to prevent further organ damage. Intravenous vasoactive drips are typically used to achieve this goal. Patients diagnosed with hypertensive emergencies often require hospitalisation in the intensive care unit (ICU) for continuous monitoring and treatment.

Hypertensive urgency: very high blood pressure with no signs of organ damage

Hypertensive urgency refers to a marked elevation in blood pressure without signs of target organ damage. While it does not warrant immediate medical attention, it still requires treatment to lower blood pressure within a day or two.

People with hypertensive urgency may experience symptoms such as a headache, dizziness, shortness of breath, chest pain, vomiting, or vision changes. However, it is important to note that hypertensive urgency usually does not present any symptoms, and the only way to know is by checking your blood pressure. If you experience these symptoms or have concerns about your blood pressure, it is crucial to contact your healthcare provider for guidance.

Specific cut-off values have been proposed for hypertensive urgency, such as a systolic blood pressure greater than 180 mmHg or a diastolic blood pressure greater than 110 mmHg. However, these values are arbitrarily derived and not linked to short-term health risks. As a result, the term "hypertensive urgency" may be more appropriately applied to patients with severely elevated blood pressure and a substantial risk of progressive end-organ damage, such as congestive heart failure or chronic kidney disease.

Over time, hypertensive urgencies are associated with a higher likelihood of adverse cardiovascular events. Therefore, a comprehensive approach is necessary to improve blood pressure control, address factors contributing to elevated blood pressure, and ensure consistent follow-up with healthcare providers. This may include medication adjustments or further hospital testing, observation, and medical management if outpatient treatment is ineffective.

Treatment: blood pressure reduction, lifestyle changes, and medication

High blood pressure, or hypertension, is a common health problem that can lead to serious health issues if left untreated. While high blood pressure often doesn't cause any noticeable symptoms, it can lead to a hypertensive crisis, which is a medical emergency. A hypertensive crisis occurs when blood pressure surges to 180/120 mm Hg or higher, and it can cause life-threatening issues with the heart, lungs, or brain. Therefore, it is important to manage high blood pressure through treatment and lifestyle changes.

Blood Pressure Reduction

If you are experiencing a hypertensive crisis, it is important to call for medical help immediately. Treatment for high blood pressure aims to reduce blood pressure to less than 130/80 mm Hg for most healthy adults. This may vary depending on age and health conditions, especially for those older than 65.

Lifestyle Changes

Lifestyle changes can play a crucial role in managing high blood pressure and may even reduce the need for medication. Here are some recommended lifestyle changes:

• Eat a healthy diet: The Dietary Approaches to Stop Hypertension (DASH) diet is recommended, which includes whole grains, fruits, vegetables, lean meats, poultry, fish, low-fat dairy, and nuts. Reduce saturated and trans fats, limit sodium intake to 1,500 mg per day or less, and increase potassium intake through natural sources.
• Exercise more: Regular physical activity can help keep your blood pressure readings in check.
• Manage stress: Find healthy ways to cope with stress, such as meditation, yoga, or deep breathing exercises.
• Maintain a healthy weight: Losing even a few extra pounds can lower blood pressure, especially if you have a large waist circumference.
• Monitor your blood pressure: Use a home monitor or visit your doctor regularly to check your blood pressure and ensure that any lifestyle changes are having a positive impact.

Medication

If lifestyle changes alone are not sufficient, medication may be necessary to manage high blood pressure. There are several types of blood pressure medications, and your healthcare provider will determine the best option for you based on your overall health and the severity of your hypertension. Some common types of blood pressure medications include:

• Diuretics (water pills): These help the body get rid of excess salt and water, controlling blood pressure.
• Beta-blockers: These lower the heart rate, which can help lower blood pressure.
• ACE inhibitors: These help the body produce less angiotensin, a chemical that causes arteries to narrow. By reducing angiotensin, blood vessels can relax and open up, lowering blood pressure.
• Angiotensin II receptor blockers: These block brain signals that can increase heart rate and narrow blood vessels, thereby lowering blood pressure.
• Calcium channel blockers: These medications work by blocking calcium from entering the cells of the heart and blood vessels, leading to lowered blood pressure.

It is important to work closely with your healthcare provider to find the most effective medication or combination of medicines for you. Do not stop or change your medication without consulting your healthcare professional. Additionally, be sure to discuss any potential side effects and costs associated with the medication.

Symptoms: light-headedness, chest pain, dizziness, and headaches

A hypertensive crisis is a sudden and severe increase in blood pressure that can lead to life-threatening issues with vital organs like the heart, lungs, or brain. If your blood pressure reading reaches 180/120 mm Hg or higher, it qualifies as a hypertensive crisis, and you should seek immediate medical attention. Even if your blood pressure is in the 140s to 160s range, it is considered dangerous, and you may need to be hospitalised.

Symptoms like light-headedness, chest pain, dizziness, and headaches, when accompanied by high blood pressure, are indicative of a hypertensive crisis. Light-headedness or dizziness can be caused by a reduction in blood supply to the inner ear, which is a vital component of the body's balance control system. High blood pressure can cause this reduction by narrowing and damaging blood vessels. Dizziness can also be a side effect of medication for hypertension.

Chest pain, or angina, occurs in about 48% of people experiencing hypertensive crises. It is caused when the heart does not receive enough blood. The pain may feel like pressure or a squeezing sensation in the chest, and it is typically located in the centre or left side of the chest. It may be mild or severe.

Headaches associated with hypertension can be mild, moderate, or severe, and they often occur in the early morning. A severe headache can be a warning sign of a stroke, and you should not ignore it. If you experience any of these symptoms, along with high blood pressure, it is important to seek immediate medical attention.
