The best drug to improve ejection fraction are beta blockers (BB), angiotensin converting enzyme inhibitors (ACEi)/angiotensin receptor blockers (ARB), and mineralocorticoid receptor antagonists (MRA).
Ejection fraction is a measurement of the percentage of blood leaving the heart each time it squeezes.
When your heart squeezes, it's called a contraction.
Ejection fraction is just one of many tests your health care provider may use to see how your heart works.
The heart contracts and relaxes.
Ejection fraction in a healthy heart is 50% to 70%. With each heartbeat, 50% to 70% of the blood in your left ventricle gets pumped out to your body.
A low number can be serious.
If your ejection fraction is 35% or below, you're at high risk of developing a dangerous arrhythmia or even heart failure.
The ejection fraction is the proportion of the end-diastolic volume that is pumped out with each beat.
It is calculated as stroke volume divided by the end-diastolic volume.
Cardiac output is the amount of blood the heart pumps in one minute and is equal to the heart rate multiplied by the stroke volume.
Normal EF is in the range of 55% to 70%.
As the percentage falls, it tells the doctor that the heart failure is getting worse.
In general, if the EF falls below 30%, it's relatively severe.
A reading of 20% or below is very severe heart failure.
Getting the appropriate amount and intensity of exercise, losing weight, quitting smoking, reducing salt or excess fluids, and eating a healthier diet are some of the recommendations for improving low EF.
People with an EF under 40% may have a higher risk of dying from CHF.
However, a 2017 study reports that the 5-year life expectancy is poor among all people admitted to the hospital with heart failure regardless of their EF.
Researchers estimate the 5-year death rate is 75.4%.
