HFpEF stands for **heart failure with preserved ejection fraction**. It is a type of heart failure where the heart’s squeezing strength (ejection fraction) is often normal or near-normal, but filling is impaired. HFpEF is commonly discussed in cardiology clinics, hospitals, imaging labs, and heart failure programs. It is used as a clinical diagnosis and a framework for evaluating symptoms like shortness of breath and fluid retention.
Heart Failure with Preserved Ejection Fraction is a type of heart failure where the heart’s pumping strength is relatively normal. It describes symptoms and signs of heart failure even though the left ventricular ejection fraction is usually 50% or higher. It is commonly used in cardiology clinics, hospitals, and imaging reports to classify heart failure and guide evaluation. It is often discussed when shortness of breath, fluid retention, or exercise intolerance occurs without a “weak pump” on echocardiogram.
HFrEF means **heart failure with reduced ejection fraction**. It describes a type of heart failure where the left ventricle pumps out a lower-than-expected fraction of blood with each beat. Clinicians use HFrEF in cardiology clinics, hospitals, imaging reports, and research studies. It is a shorthand that helps guide evaluation, communication, and general treatment frameworks.
Heart Failure with Reduced Ejection Fraction is a type of heart failure where the heart’s main pumping chamber cannot squeeze as strongly as it should. It is defined using a measurement called ejection fraction, which estimates how much blood the left ventricle pumps out with each beat. It is commonly used in cardiology clinics, emergency care, and hospital medicine to classify heart failure and guide evaluation and treatment planning. It is also used in research studies and clinical guidelines to standardize care and compare outcomes.
Chronic Heart Failure is a long-term condition where the heart cannot pump or fill with blood as effectively as the body needs. It commonly causes symptoms such as shortness of breath, fatigue, or swelling that can persist or recur over time. It is used in clinics, hospitals, and imaging or lab reports to describe a sustained pattern of heart pump dysfunction and its consequences. It also appears in care planning to guide monitoring, testing, and long-term risk discussions.
Acute Heart Failure is a sudden or quickly worsening episode of heart failure symptoms. It means the heart cannot keep up with the body’s needs for blood flow and pressure in the short term. It is commonly used in emergency departments, hospitals, and cardiology services. It can occur in people with known heart failure or as a first-time presentation.
CHF most commonly refers to **congestive heart failure**, a clinical syndrome where the heart cannot pump or fill effectively. It is used in hospitals, clinics, imaging reports, and everyday conversation as a shorthand for **heart failure with fluid congestion**. Clinicians often use “heart failure” as the umbrella term, while CHF emphasizes **symptoms related to fluid buildup**.
Congestive Heart Failure is a clinical syndrome where the heart cannot pump blood effectively enough to meet the body’s needs. It often leads to fluid buildup (“congestion”) in the lungs, legs, abdomen, or other tissues. The term is commonly used in clinics and hospitals to describe a pattern of symptoms, exam findings, and test results.
Heart Failure is a clinical syndrome in which the heart cannot pump enough blood to meet the body’s needs, or can do so only with abnormally high filling pressures. It is commonly used as a diagnosis when symptoms like shortness of breath and swelling are linked to impaired heart function. It is also used to describe a long-term condition that can fluctuate between stable periods and flare-ups. Clinicians use the term in cardiology clinics, emergency care, hospital medicine, and cardiac imaging reports.
Dressler Syndrome is a type of inflammation that can happen after the heart has been injured. It most often refers to pericarditis (inflammation of the sac around the heart) occurring weeks after a heart attack or heart surgery. It is discussed in cardiology when evaluating chest pain, fever, and fluid around the heart after a cardiac event. Clinicians also use the term within the broader group called post–cardiac injury syndromes.
A Left Ventricular Aneurysm is a bulging, weakened area in the wall of the left ventricle, the heart’s main pumping chamber. It most often develops after damage to heart muscle, such as from a prior heart attack. Clinicians use the term when describing heart structure on imaging tests and when planning treatment for symptoms or complications. It is discussed in cardiology clinics, hospital care, and cardiothoracic surgery planning.
Ventricular Septal Rupture is a tear in the wall (septum) that separates the heart’s two lower chambers. It creates an abnormal opening that lets blood pass between the left ventricle and right ventricle. It most often occurs as a complication after a heart attack, but it can happen in other settings. Clinicians use the term when diagnosing sudden heart failure or shock and when planning urgent repair.
Papillary Muscle Rupture is a tear of a small muscle inside the heart that helps the mitral valve close properly. It most often happens suddenly after a heart attack and can cause severe mitral valve leakage. It is commonly discussed in emergency cardiology, critical care, echocardiography, and cardiac surgery. It is an important diagnosis because it can lead to rapid heart and lung failure without prompt recognition.
Mechanical Complication of MI means a structural problem caused by heart muscle damage after a myocardial infarction (MI), also called a heart attack. It refers to physical “breakdowns” in the heart’s walls, valves, or supporting structures. The term is commonly used in emergency care, cardiac intensive care units, echocardiography labs, and cardiothoracic surgery discussions. It helps clinicians describe urgent, high-risk causes of shock, new heart murmurs, or sudden worsening after MI.
Cardiogenic Shock is a life-threatening state where the heart cannot pump enough blood to meet the body’s needs. It can happen suddenly, most commonly during or after a major heart problem such as a heart attack. It is discussed in emergency care, intensive care, and cardiology because it affects blood pressure and organ perfusion. It is a clinical diagnosis that guides how clinicians prioritize testing and urgent supportive treatments.
Coronary Microvascular Dysfunction describes problems in the heart’s smallest blood vessels that can limit blood flow. It can cause chest discomfort or shortness of breath even when larger coronary arteries look normal or only mildly narrowed. It is commonly discussed in cardiology when evaluating angina symptoms, “normal” angiograms, or ischemia on stress testing. It is also relevant in some people with heart failure symptoms despite a normal pumping function.
MINOCA stands for myocardial infarction with non-obstructive coronary arteries. It describes a heart attack pattern where angiography does not show a major blocked coronary artery. MINOCA is commonly used in emergency cardiology and cardiac catheterization (cath) lab reports. It is best understood as a “working diagnosis” that prompts a careful search for the true cause.
Microvascular Angina is chest discomfort or angina-like symptoms caused by problems in the heart’s smallest blood vessels. It can occur even when the major coronary arteries look normal or only mildly narrowed on angiography. It is commonly discussed in cardiology clinics and chest pain evaluations when symptoms persist without a clear “blocked artery” explanation. It is also referred to within the broader concept of ischemia with no obstructive coronary arteries (often shortened to INOCA).
Vasospastic Angina is chest discomfort caused by a temporary spasm (sudden tightening) of a coronary artery. The spasm briefly reduces blood flow to part of the heart muscle, even when an artery may look normal between episodes. It is commonly discussed in cardiology clinics and emergency settings when symptoms occur at rest or in cycles (often at night or early morning).
Prinzmetal Angina is chest discomfort caused by a temporary spasm of a coronary artery. It typically happens at rest rather than during exercise. It can produce short-lived but significant reductions in blood flow to the heart muscle. Clinicians use the term to describe a specific pattern of angina linked to coronary vasospasm.
