A type of heart failure medication that works by preventing the body from creating angiotensin, a substance in the blood that causes vessels to tighten and raises blood pressure. In large-scale studies, ACE inhibitors have been proven to slow the progression of heart failure.
A written document that states a person’s healthcare choices and names someone to make those choices, should the person become unable to make their own decisions about medical care. The most common types of Advance Directives are a living will and a durable power of attorney for healthcare.
A reduction in the amount of oxygen-carrying red blood cells. Anemia can have many causes, but the most common is a lack of iron in the body. Also known as iron-poor blood.
An X-ray test used to detect diseases of the blood vessels, such as weakening of the vessel walls and the narrowing or blocking of vessels. The X-ray is taken after the vessels have been injected with a substance that allows them to be seen on film.
A procedure that reopens blocked blood vessels to the heart. A physician inserts a hollow needle (catheter) into the diseased artery and pushes a small deflated balloon into the blocked section. Then the physician inflates the balloon to widen the artery.
A medication that blocks the action of a special chemical called angiotensin, which normally raises the heart rate and blood pressure.
An abnormal rhythm or rate of the heartbeat caused by disturbances in the movement of electrical impulses through the heart.
Rapid, uneven contractions in the upper heart chambers (atria), which cause the lower chambers (ventricles) to beat irregularly.
One of the two upper chambers of the heart.

Medications, such as warfarin and heparin, used to prevent blood clotting. Some people with heart failure are prescribed blood thinners to reduce the risk of stroke.
A drug that prevents calcium from entering the heart’s muscle cells. This causes the muscles to relax, lowering the heart rate.
A supervised program of increasing exercise, mental support and training to allow a person with a heart condition to resume normal activities.
A doctor who diagnoses and treats heart problems.
A weakening or deformity of the heart muscle that causes decreased pumping force. This leads to less-efficient circulation of blood through the lungs and the rest of the body. See image of Hypertrophic Cardiomyopathy.
An investigational surgical treatment for heart failure that involves taking muscles from the person’s back or abdomen and wrapping them around the heart. Its goal is to increase the heart’s pumping power.
Anyone who helps a chronically ill patient cope with an illness. Caregivers can be home healthcare workers, family members or friends. They assist in many ways, from making sure patients take their medications properly to helping out with day-to-day activities
An illness or condition that develops slowly and persists for a long time. Heart failure is almost always a chronic illness.
Any heart condition or abnormality that a person was born with.
A common form of heart failure that results in a patient retaining excessive fluid, often leading to swelling of the legs and ankles and congestion in the lungs.
A procedure used to reroute the blood supply around a blocked section of a coronary artery. Surgeons remove healthy blood vessels from another part of the body, such as a leg or the chest wall. Then they surgically attach the vessels to the diseased artery to let the blood flow around the blocked section.
A condition caused by thickening of the walls of the arteries that supply blood to the heart muscle. When these arteries become blocked, the heart is deprived of oxygen and can become damaged. Severe cases can result in heart attack.
A device that delivers pacing or an electric countershock to the heart when an abnormal rhythm is detected. A surgically implantable version is called a pacemaker. المتأهلين لكأس العالم للأندية 2022
Insulin is a hormone that allows cells to absorb glucose [sugar] from the bloodstream. Diabetes is a condition in which the body doesn’t produce the right amount of insulin or does not use insulin effectively and the glucose (sugar) level in the bloodstream is elevated (hyperglycemia). Type I diabetes is usually controlled with insulin injections. Type II diabetes is usually controlled with pills or a special diet.
The pressure of blood inside arteries when the heart is at rest. This is the bottom number in a blood pressure reading. baloot
A medication that increases the force of the heart’s contractions and slows certain types of irregular heartbeats (arrhythmia).
A medication that promotes the formation and release of urine. It helps to reduce fluid overload in people with heart failure. Also called a water pill.
A change in the effect of a drug when taken with a certain other drug or food. Its effect may increase or decrease, or a side effect may occur
A disturbance in heart rhythm, sometimes used as an alternative to the term “arrhythmia.”
Difficult or labored breathing, often caused by heart conditions.
A test that obtains an image of the structure and motion of the heart using ultrasound (inaudible, high-frequency sound waves). Used to detect cardiomyopathy and other abnormalities of the heart wall, valves and large blood vessels.
An abnormal accumulation of fluid in body tissues. Edema is common in the legs, ankles and lungs of people with heart failure.
The amount of blood released during each contraction of the lower ventricle of the heart. It’s usually expressed as a percentage: an ejection fraction of 60 percent means that 60 percent of the total amount of blood in the left ventricle is expelled with each heartbeat.
A record of the electrical activity of the heart, allowing diagnosis of abnormal heart conditions.
Inflammation of the lining of the heart and the heart valves, usually due to bacterial infection.
Sudden death of a portion of the heart muscle caused by a sudden decrease in blood supply to that area. Also known as myocardial infarction or MI.
The most prevalent form of heart disease, in which narrowed or blocked coronary arteries result in decreased blood supply.
The inability of the heart to keep up with its workload. When someone has this condition, their heart can’t pump enough blood to the lungs and the rest of the body. Heart failure is often a chronic condition that can be treated with medications, diet and other lifestyle changes, and in some cases, surgery
Surgery that replaces a damaged heart with a healthy heart taken from a donor who has been declared brain dead.
One of the four structures in the heart that control the flow of blood by opening and closing with each heartbeat. The valves permit blood to flow in only one direction.
The medical term for high blood pressure.
Overactivity of the thyroid gland, leading to overproduction of thyroid hormones. It can make the body’s metabolism overactive, leading to symptoms such as weight loss and rapid heart rate.
Abnormally low blood pressure.
Heart failure in which the left side of the heart must work harder to pump the same amount of blood. This type of heart failure usually causes breathing difficulties.
A mechanical pump used to aid the natural pumping action of the heart’s left ventricle.
A test in which a radioactive tracer is injected into the bloodstream and scanned as it passes through the heart. A computer then calculates the size and shape of a patient’s ventricles based on the amount and distribution of radiation they emit.
Inflammation of the heart muscle.
Sudden death of a portion of the heart muscle caused by a sudden decrease in blood supply to that area.
A mineral that, together with sodium and calcium, regulates the body’s water balance, maintains normal heart rhythm, and is responsible for nerve impulse conduction and muscle contraction.
A general internist or family physician who provides patients with routine preventive healthcare and is their first contact when medical problems arise.
Fluid in lung tissues, often caused by congestive heart failure.
Heart failure caused by damage to the right-side chambers of the heart, leading to decreased blood flow, and swelling in the hands, legs and abdomen.
Any reaction that results from a medication or therapy. Heart failure medications can cause side effects such as headaches, nausea, dizziness, kidney complications and low blood pressure.
A mineral that, together with potassium and calcium, regulates the body’s water balance, maintains normal heart rhythm, and is responsible for nerve impulse conduction and muscle contraction. Excessive intake of sodium from food contributes to high blood pressure in most people. In people who already have high blood pressure, too much sodium may increase the risk of stroke, heart disease and kidney damage.
An exercise test that examines how well the heart works. Patients are asked to walk on a treadmill to increase their heart rate. During the test, a doctor monitors electrocardiogram (ECG or EKG) readings from the heart to check for any heart rhythm irregularities . تريكس
