Ejection fraction is one of the evaluation indicators of the heart’s pumping capacity. Physiological factors such as emotional excitement and the use of cardiotonic drugs such as digoxin can improve the ejection fraction. 1. Physiological factors: normal people do not need the heart to use all the ability to pump blood, the heart pumping capacity has a certain reserve, when encountering emotional excitement, external environmental stimuli, heavy physical labor or sports and other situations, nerve excitement caused by the heart’s contractility and heart rate will be greatly enhanced, so that the ejection fraction increased. 2. Drug factors: For some patients with certain diseases, drugs can be used to promote the increase of cardiac ejection fraction. (1) Drugs to reduce ejection resistance: you can use sodium nitroprusside, hydrochlorothiazide, captopril and so on to reduce peripheral resistance, reduce the resistance of the heart to ejection and increase the ejection fraction. (2) Enhancement of myocardial contractility drugs: cardiotonic drugs such as digoxin can be used to increase myocardial contractility and increase the ejection fraction. (3) Increase ventricular filling drugs: you can use drugs such as metoprolol to reduce heart rate, increase ventricular filling and increase ejection. Clinical treatment of heart failure and other diseases usually use a variety of drugs together to improve ejection function. The appearance of the above diseases need to be timely consultation. The above drugs need to be used under the guidance of clinicians, unauthorized use of drugs is prohibited.
