Divide mileage by fuel usage to see your car's fuel consumption. This tells you how many miles you drove per gallon of gas. For example, if you drove 335 miles before refueling, and you filled your car up with 12 gallons of gas, your fuel consumption was 27.9 miles per gallon, or mpg (335 miles / 12 gallon = 27.9 mpg).
Failure on the left side is linked to a general weakening of the heart muscle. This is the more common type of heart failure. The weakened heart muscle no longer can keep up with the demands of the body for oxygen-rich blood. Back-up into the lungs occurs. Symptoms of left-side heart failure include: 1  Tiredness (fatigue). 2  Shortness of breath. 3  Asthma-like wheezing.
Diastolic heart failure may not lower the heart's ejection fraction. Ejection fraction is a measurement of how well the heart is pumping out blood. This ejection fraction is typically lower in people who have systolic heart failure.But in diastolic heart failure, your left ventricle may pump well during systole; it is just not filling with enough blood during diastole.iastolic heart failure may not lower the heart's ejection fraction. Ejection fraction is a measurement of how well the heart is pumping out blood. This ejection fraction is typically lower in people who have systolic heart failure.
