Avocadoes are rich in omega-3, delivering 160 milligrams per cup of alpha-linolenic acid. To get the most nutritional value from avocadoes, avoid those which have become over-ripe. You can identify these at the store because they will have dents and feel overly soft when you hold them.
Ejection fraction. An ejection fraction (EF) is the fraction of blood ejected from a ventricle of the heart with each heartbeat. EF is readily compared with the ancient term Systole, understood as a Gathering of the heart's fibers.
Heart valve problems. An ejection fraction between 40 and 50 percent may indicate damage to the heart muscle (e.g., from a prior heart attack). Typically, this EF level alone is not low enough to lead to heart failure. But a very low ejection fraction of only 15-25% is indicative of a failing heart or cardiomyopathy.
