(+info)White coat hypertension (WCH) is a phenomenon where a patient's blood pressure (BP) is persistently higher in a clinical setting, such as a doctor's office or hospital, compared to measurements taken in other settings. This increase in BP is often attributed to the anxiety or stress experienced by the patient due to the medical environment and the presence of healthcare providers, particularly when wearing a white coat.
To medically define WCH, the following criteria are generally used:
1. The office or clinical blood pressure readings are ≥ 140 mmHg systolic and/or ≥ 90 mmHg diastolic on at least two separate occasions.
2. Out-of-office blood pressure readings, such as home measurements or 24-hour ambulatory blood pressure monitoring (ABPM), are consistently normal (< 135 mmHg systolic and < 85 mmHg diastolic).
It is essential to distinguish white coat hypertension from sustained hypertension, as the latter requires appropriate treatment. While WCH itself is not considered a disease, it may indicate an increased risk of developing essential hypertension in the future. Regular out-of-office blood pressure monitoring and lifestyle modifications are often recommended for patients with white coat hypertension to help manage their cardiovascular health.
Ambulatory Blood Pressure Monitoring (ABPM) is a non-invasive method of measuring blood pressure at regular intervals over a 24-hour period or more. This is typically done using a portable device that is worn on a belt around the waist and connected to a cuff wrapped around the upper arm. The device automatically inflates the cuff and records blood pressure readings at preset intervals, usually every 15 to 30 minutes during the day and every 30 to 60 minutes during the night.
ABPM provides valuable information about blood pressure patterns over an extended period, including how it varies throughout the day and in response to daily activities, posture changes, and sleep. This can help healthcare providers diagnose and manage hypertension more effectively, as well as assess the effectiveness of antihypertensive medications. ABPM is also useful for identifying white coat hypertension, a condition where blood pressure readings are higher in a medical setting than in daily life.
Overall, ambulatory blood pressure monitoring is an important tool in the diagnosis and management of hypertension and related cardiovascular diseases.
In the context of medical terminology, "office visits" refer to patients' appointments or consultations with healthcare professionals in their respective offices or clinics. These visits may include various services such as physical examinations, diagnosis, treatment planning, prescribing medications, providing referrals, and offering counseling or education on health-related topics. Office visits can be for routine checkups, follow-up appointments, or addressing acute or chronic medical concerns. It is important to note that office visits do not include services provided in a hospital setting, emergency department, or other healthcare facilities.
Blood pressure determination is the medical procedure to measure and assess the force or pressure exerted by the blood on the walls of the arteries during a heartbeat cycle. It is typically measured in millimeters of mercury (mmHg) and is expressed as two numbers: systolic pressure (the higher number, representing the pressure when the heart beats and pushes blood out into the arteries) and diastolic pressure (the lower number, representing the pressure when the heart rests between beats). A normal blood pressure reading is typically around 120/80 mmHg. High blood pressure (hypertension) is defined as a consistently elevated blood pressure of 130/80 mmHg or higher, while low blood pressure (hypotension) is defined as a consistently low blood pressure below 90/60 mmHg. Blood pressure determination is an important vital sign and helps to evaluate overall cardiovascular health and identify potential health risks.
Hypertension is a medical term used to describe abnormally high blood pressure in the arteries, often defined as consistently having systolic blood pressure (the top number in a blood pressure reading) over 130 mmHg and/or diastolic blood pressure (the bottom number) over 80 mmHg. It is also commonly referred to as high blood pressure.
Hypertension can be classified into two types: primary or essential hypertension, which has no identifiable cause and accounts for about 95% of cases, and secondary hypertension, which is caused by underlying medical conditions such as kidney disease, hormonal disorders, or use of certain medications.
If left untreated, hypertension can lead to serious health complications such as heart attack, stroke, heart failure, and chronic kidney disease. Therefore, it is important for individuals with hypertension to manage their condition through lifestyle modifications (such as healthy diet, regular exercise, stress management) and medication if necessary, under the guidance of a healthcare professional.
Blood pressure is the force exerted by circulating blood on the walls of the blood vessels. It is measured in millimeters of mercury (mmHg) and is given as two figures:
1. Systolic pressure: This is the pressure when the heart pushes blood out into the arteries.
2. Diastolic pressure: This is the pressure when the heart rests between beats, allowing it to fill with blood.
Normal blood pressure for adults is typically around 120/80 mmHg, although this can vary slightly depending on age, sex, and other factors. High blood pressure (hypertension) is generally considered to be a reading of 130/80 mmHg or higher, while low blood pressure (hypotension) is usually defined as a reading below 90/60 mmHg. It's important to note that blood pressure can fluctuate throughout the day and may be affected by factors such as stress, physical activity, and medication use.
Echocardiography is a medical procedure that uses sound waves to produce detailed images of the heart's structure, function, and motion. It is a non-invasive test that can help diagnose various heart conditions, such as valve problems, heart muscle damage, blood clots, and congenital heart defects.
During an echocardiogram, a transducer (a device that sends and receives sound waves) is placed on the chest or passed through the esophagus to obtain images of the heart. The sound waves produced by the transducer bounce off the heart structures and return to the transducer, which then converts them into electrical signals that are processed to create images of the heart.
There are several types of echocardiograms, including:
* Transthoracic echocardiography (TTE): This is the most common type of echocardiogram and involves placing the transducer on the chest.
* Transesophageal echocardiography (TEE): This type of echocardiogram involves passing a specialized transducer through the esophagus to obtain images of the heart from a closer proximity.
* Stress echocardiography: This type of echocardiogram is performed during exercise or medication-induced stress to assess how the heart functions under stress.
* Doppler echocardiography: This type of echocardiogram uses sound waves to measure blood flow and velocity in the heart and blood vessels.
Echocardiography is a valuable tool for diagnosing and managing various heart conditions, as it provides detailed information about the structure and function of the heart. It is generally safe, non-invasive, and painless, making it a popular choice for doctors and patients alike.
Clothing is not a medical term, but rather a general term used to describe items worn on the body for various reasons such as protection from the elements, modesty, or fashion. In a medical context, clothing may be referred to in relation to certain conditions or treatments that require special garments, such as compression stockings for deep vein thrombosis or protective gear for athletes. However, there is no specific medical definition for 'clothing'.
Pulmonary hypertension is a medical condition characterized by increased blood pressure in the pulmonary arteries, which are the blood vessels that carry blood from the right side of the heart to the lungs. This results in higher than normal pressures in the pulmonary circulation and can lead to various symptoms and complications.
Pulmonary hypertension is typically defined as a mean pulmonary artery pressure (mPAP) greater than or equal to 25 mmHg at rest, as measured by right heart catheterization. The World Health Organization (WHO) classifies pulmonary hypertension into five groups based on the underlying cause:
1. Pulmonary arterial hypertension (PAH): This group includes idiopathic PAH, heritable PAH, drug-induced PAH, and associated PAH due to conditions such as connective tissue diseases, HIV infection, portal hypertension, congenital heart disease, and schistosomiasis.
2. Pulmonary hypertension due to left heart disease: This group includes conditions that cause elevated left atrial pressure, such as left ventricular systolic or diastolic dysfunction, valvular heart disease, and congenital cardiovascular shunts.
3. Pulmonary hypertension due to lung diseases and/or hypoxia: This group includes chronic obstructive pulmonary disease (COPD), interstitial lung disease, sleep-disordered breathing, alveolar hypoventilation disorders, and high altitude exposure.
4. Chronic thromboembolic pulmonary hypertension (CTEPH): This group includes persistent obstruction of the pulmonary arteries due to organized thrombi or emboli.
5. Pulmonary hypertension with unclear and/or multifactorial mechanisms: This group includes hematologic disorders, systemic disorders, metabolic disorders, and other conditions that can cause pulmonary hypertension but do not fit into the previous groups.
Symptoms of pulmonary hypertension may include shortness of breath, fatigue, chest pain, lightheadedness, and syncope (fainting). Diagnosis typically involves a combination of medical history, physical examination, imaging studies, and invasive testing such as right heart catheterization. Treatment depends on the underlying cause but may include medications, oxygen therapy, pulmonary rehabilitation, and, in some cases, surgical intervention.
Protective clothing refers to specialized garments worn by healthcare professionals, first responders, or workers in various industries to protect themselves from potential hazards that could cause harm to their bodies. These hazards may include biological agents (such as viruses or bacteria), chemicals, radiological particles, physical injuries, or extreme temperatures.
Examples of protective clothing include:
1. Medical/isolation gowns: Fluid-resistant garments worn by healthcare workers during medical procedures to protect against the spread of infectious diseases.
2. Lab coats: Protective garments typically worn in laboratories to shield the wearer's skin and clothing from potential chemical or biological exposure.
3. Coveralls: One-piece garments that cover the entire body, often used in industries with high exposure risks, such as chemical manufacturing or construction.
4. Gloves: Protective hand coverings made of materials like latex, nitrile, or vinyl, which prevent direct contact with hazardous substances.
5. Face masks and respirators: Devices worn over the nose and mouth to filter out airborne particles, protecting the wearer from inhaling harmful substances.
6. Helmets and face shields: Protective headgear used in various industries to prevent physical injuries from falling objects or impact.
7. Fire-resistant clothing: Specialized garments worn by firefighters and those working with high temperatures or open flames to protect against burns and heat exposure.
The choice of protective clothing depends on the specific hazards present in the work environment, as well as the nature and duration of potential exposures. Proper use, maintenance, and training are essential for ensuring the effectiveness of protective clothing in minimizing risks and maintaining worker safety.
A "Dental Service, Hospital" is a specialized department or unit within a hospital that provides comprehensive dental care services to patients. This type of service is typically equipped with advanced dental technology and staffed by oral health professionals such as dentists, oral surgeons, orthodontists, endodontists, periodontists, and dental hygienists.
The dental services offered in a hospital setting may include preventive care, restorative treatments, oral surgery, prosthodontics (dentures and implants), periodontal therapy, endodontic treatment (root canals), orthodontic treatment, and specialized care for patients with medical conditions that affect their oral health.
Hospital dental services often provide care to patients who require complex or extensive dental treatments, have medical conditions that make it difficult to receive dental care in a traditional dental office setting, or those who are recovering from surgery or other medical procedures. They may also provide emergency dental care for patients with severe dental pain, infection, or trauma.
In summary, a "Dental Service, Hospital" is a specialized unit within a hospital that provides comprehensive dental care services to patients, typically offering advanced technology and staffed by oral health professionals.
An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.
