CAD most often refers to **coronary artery disease**. It describes disease in the arteries that supply blood to the heart muscle. It is commonly discussed in chest pain evaluation, heart attack care, and long-term heart risk management. Clinicians use CAD as a shared term for diagnosis, planning tests, and guiding treatment goals.

Coronary Artery Disease is a condition where the heart’s own arteries develop narrowing or blockage, most often from cholesterol-rich plaque. It can reduce blood flow (oxygen delivery) to heart muscle and lead to symptoms like chest discomfort or shortness of breath. It is commonly used as a clinical diagnosis in cardiology clinics, emergency departments, and hospital care. It also appears in test reports (stress tests, CT scans, angiograms) and guides prevention and treatment planning.

Narrow Pulse Pressure means the difference between the top and bottom blood pressure numbers is smaller than expected. Pulse pressure is calculated as systolic blood pressure minus diastolic blood pressure. Clinicians use it as a quick clue about how much blood the heart ejects and how the arteries behave. It is most commonly discussed in vital signs review, emergency care, and cardiovascular evaluation.

Wide Pulse Pressure is a larger-than-expected difference between the top and bottom blood pressure numbers. Pulse pressure is calculated as systolic blood pressure minus diastolic blood pressure. It is commonly discussed during routine blood pressure checks, heart evaluations, and vascular assessments. Clinicians use it as a clue about how the heart and arteries are working together.

Hypotension means blood pressure that is lower than expected for the person and situation. It can be a normal finding in some people and a warning sign in others. Clinicians use the term to describe a measurement and to frame symptoms like dizziness or fainting. It is commonly discussed in cardiology, emergency care, anesthesia, and critical care.

Hypertension means persistently elevated blood pressure in the arteries. It is commonly called “high blood pressure.” Clinicians use the term in primary care, cardiology, nephrology, and perioperative medicine. It is discussed in clinics, hospitals, and preventive health settings because it influences long-term cardiovascular risk.

Tachycardia means a faster-than-expected heart rate. In adults, clinicians often use the term when the resting heart rate is above about 100 beats per minute. Tachycardia is discussed in clinics, emergency departments, and hospital wards because it can be a normal response or a sign of illness. It is also a key descriptor when interpreting an electrocardiogram (ECG) and heart rhythm monitoring.

Bradycardia means a heart rate that is slower than expected for a person’s age and situation. In adults, it is commonly discussed when the resting heart rate is below about 60 beats per minute, but context matters. It is a clinical finding that can be normal (for example, during sleep or in trained athletes) or related to heart or systemic conditions. The term is widely used in cardiology, emergency medicine, anesthesia, and primary care.

Irregular Pulse means the heartbeat rhythm felt at the wrist, neck, or other artery does not follow a steady pattern. It can feel like skipped beats, extra beats, or an uneven “random” rhythm. It is commonly noticed during a home pulse check, a vital-sign assessment, or a clinician’s cardiovascular exam. It is a *finding*, not a diagnosis, and it often prompts rhythm-focused evaluation.

Thready Pulse describes a pulse that feels weak, thin, and difficult to feel. It is usually assessed by palpating an artery, such as the radial pulse at the wrist. Clinicians use it as a bedside clue about blood flow and overall circulation. It is most often discussed in urgent care, emergency, perioperative, and inpatient settings.

Bounding Pulse is a pulse that feels unusually strong and forceful when a clinician or patient palpates an artery. It is a bedside sign used during routine vital-sign checks and cardiovascular exams. It can reflect normal short-term physiology (like after exercise) or an underlying medical condition. Clinicians interpret it alongside blood pressure, symptoms, and the overall exam.

Delayed Capillary Refill is a clinical finding that suggests slower-than-expected return of blood to the skin after brief pressure. It is usually checked at a fingertip, nail bed, toe, or sometimes the chest in infants. Clinicians use it as a quick bedside clue about circulation and overall perfusion (blood flow reaching tissues). It is most often discussed in emergency, critical care, and cardiovascular assessments.

Cool Extremities means the hands, feet, or limbs feel cooler than expected on touch or to the patient. It is a clinical finding and symptom, not a diagnosis by itself. It is commonly discussed in cardiovascular care because it can reflect reduced blood flow or reduced overall perfusion. Clinicians use it as part of the bedside exam alongside pulses, blood pressure, and skin color.

Pulmonary Edema is fluid buildup in the lungs, especially in the tiny air sacs (alveoli). It can make breathing feel difficult because air and fluid compete for the same space. It is commonly discussed in emergency care and cardiology because it is often related to heart problems. Clinicians also use the term in critical care when lung injury, infection, or other illnesses cause fluid leakage into the lungs.

Rales are abnormal breath sounds heard with a stethoscope over the lungs. They are often described as “crackles” and are most noticeable during breathing in. Clinicians commonly document Rales during a heart and lung exam in clinics, emergency departments, and hospitals. In cardiovascular care, Rales can be a clue to fluid in the lungs, such as with heart failure.

Crackles are abnormal breath sounds heard with a stethoscope. They often sound like popping, bubbling, or crackling during breathing in. Clinicians commonly listen for Crackles during heart and lung examinations. They can be an important clue in conditions such as heart failure and fluid in the lungs.

Hepatojugular Reflux is a bedside physical exam finding used to assess how the right side of the heart handles extra blood returning to it. It is checked by watching the neck veins while gentle, sustained pressure is applied to the abdomen. A sustained rise in the visible neck vein pulse can suggest elevated right-sided heart filling pressures. It is most commonly used in cardiology and internal medicine when evaluating shortness of breath, fluid retention, or suspected heart failure.

JVD means **jugular venous distention**, a visible fullness of the neck veins. It is a **bedside clinical sign** that can suggest higher-than-normal pressure in the venous system returning blood to the heart. Clinicians most often look for JVD during a physical exam in people with **shortness of breath, swelling, or suspected heart failure**. It is commonly discussed in cardiology, emergency medicine, internal medicine, and critical care.

Jugular Venous Distension is a visible fullness or bulging of the neck veins caused by increased pressure in the venous system. It is most often assessed by looking at the internal jugular vein on the right side of the neck. Clinicians use it as a bedside sign of how well the right side of the heart is handling blood returning to the chest. It is commonly referenced in emergency, inpatient, and outpatient cardiovascular evaluations.

S4 Gallop is an extra heart sound that can be heard with a stethoscope just before the normal first heart sound. It is often described as a low-pitched “thump” at the end of the heart’s filling phase. Clinicians use it as part of the bedside cardiac exam to look for clues about how stiff or noncompliant a ventricle may be. It is most often discussed in cardiology, internal medicine, emergency care, and perioperative settings.
