What Is a Gallbladder ejection fraction?

A: A gallbladder ejection fraction is part of a hepatobiliary iminodiacetic acid scan (HIDA), a medical test performed to diagnose acalculous biliary pain (ABP), among other conditions. ABP is characterized by an intermittent crampy pain on the right side of the upper abdomen that is often triggered by eating fatty foods but not caused by gallstones. During the scan, a hormone is injected into the gallbladder, causing it to contract. The rate at which the gallbladder releases bile is the gallbladder ejection fraction. A normal gallbladder ejection fraction is usually greater than 35 percent.. The gallbladder is a sac that stores bile from the...


What Are the Different Ways to Increase ejection fraction?

A: Cardiovascular physiology refers to the different functions of the heart and circulatory system and the study of the factors that affect them. The human heart is responsible for circulating nutrient-rich blood to all of the body`s organs and tissues, hence making it possible to maintain life. ejection fraction refers to the relative amount of blood that is pumped out of both the right and left ventricles with each contraction of the heart. There are a number of ways to increase ejection fraction, with regular exercise and a heart-healthy diet being the safest and most effective.. Like any machine, there are times when the heart is functioning efficiently and healthily. Other times, different...


What is normal cardiac ejection fraction? How is ejection fraction improved?

A: Cardiac ejection fractions measure the fraction of blood that is pumped out of the ventricles of the heart with every beat. In general, ejection fraction refers to the measurement of the left ventricle. However, the measurement for the right ventricle can also be determined. Typically, a healthy individual will have an ejection fraction between 55-70%. The ejection fraction may decrease if: there is weakened heart muscle, such as dilated cardiomyopathy; a heart attack has damaged the heart; there are heart valve problems; there is long-standing, uncontrolled high blood...


Can someone tell how serious is a heart ejection fraction of 15-25% Is ?

A: ask a professional ok :) Anything above 50% is normal, would probably experience fatigue with exertion. This is what is considered severe heart failure and people with this level of pump dysfunction usually get an AICD because they are at increased risk of fatal ventricular arrhythmias. If you are who you know has this, they have to be followed by a cardiologist regularly. There are at least five drugs this person should be on: aspirin, beta blocker, ace-inhibitor, digoxin and aldactone unless there are contraindications. It signifies near death and the need for a heart transplant . ejection fraction (EF) is a measurement of how well the heart is pumping. It represents a percentage of the total blood volume in the left ventricle that is...


What Is Preserved ejection fraction?

A: A body`s ejection fraction refers to the measure of blood that the heart pumps with each contraction from its two ventricles. ejection from the left and right ventricles can be measured, though it is the left ventricle reading that concerns most physicians. A depressed ejection fraction of below 50 percent may indicate recent heart failure, with lower scores signaling the onset of heart disease. A preserved ejection fraction, by contrast, is above 50 percent and means the body is getting the oxygenated blood it needs to keep trudging on.. A range of tests can measure whether the heart has a preserved


What Is the Left Ventricular ejection fraction?

A: The left ventricular ejection fraction (LVEF) is a measure of the heartís ability to pump blood. It is measured by echocardiography (ECHO) and is used to diagnose and monitor heart failure. High or low LVEF values suggest the heart is not working properly.. The heart is a four-chambered organ with two atria and two ventricles. The right side of the heart pumps blood to the lungs, where the blood can pick up oxygen and release carbon dioxide. After circulating through the lungs, the blood returns to the left side of the heart. The blood is then distributed through the rest of the body by the pumping of the left ventricle.. The left ventricular ejection fraction is a measurement used to assess...


What Is the ejection fraction for Heart Failure?

A: The ejection fraction for heart failure is a number used to determine how effectively a patient`s heart is pumping. An ejection fraction of 55 percent is an indication that the heart is working well. Patients with a ejection fraction number under 40 may be in heart failure and need medical treatment to improve this organ`s function. A doctor can order tests and suggest a course of treatment that may include lifestyle changes and medications if heart failure is confirmed.. The heart works like a pump inside the body to keep organs, muscles and cells supplied with oxygenated blood. A normal heart beat has a "ka-thump" rhythm, which indicates...


What Are the Effects of Low ejection fraction?

A: A low ejection fraction (EF), also known as a low left ventricular ejection fraction (LVEF), indicates that an inadequate amount of blood is squeezed from the left ventricle with each heart beat to oxygenate the body. Measured variously by echocardiogram, cardiac catherization, during a cardiac stress test or other diagnostic testing, a normal ejection fraction is usually 50 to 70 percent of the ventricular volume. A low ejection fraction is considered to be 35 to 40 percent, or less, of ventricular volume and is indicative of systolic heart failure or congestive heart failure (CHF). Effects...


What is an ejection fraction?

A: An ejection fraction is a measurement that tells what percentage of blood is pumped out of a ventricle in the heart with each beat. It is usually measured from the left ventricle, which is the main pumping chamber in the heart. Sometimes it is qualified as the right ventricle ejection fraction (RVEF) to refer to the amount of blood delivered to the lungs. During a heartbeat, the heart muscle contracts and relaxes just like any other muscle during activity. The relaxation allows the ventricles, or chambers, to fill with blood. The contraction forces the blood back out. The strength of the heart and clarity of arteries determines how much blood will be pushed out and circulated throughout the...

What Factors Affect ejection fraction Values?

A: Since ejection fraction values deal with the pumping action of the ventricles, any condition that reduces this activity affects the values. Ineffective blood circulation to the heart or ineffective ventricle filling combined with faulty valves, weakened muscle tissue, or tissue death all contribute to the amount of blood leaving the heart. Cardiologists generally use imaging studies to evaluate heart action and ejection fraction values. Treatment depends on the cause of the low values.. Physicians determine ejection fraction values by dividing the stroke volume by the end diastolic volume of primarily the left ventricle. The stroke volume is...
