If an echocardiogram showed L. ventricular hypertrophy and ejection fraction 45%. What would this mean?
WHOA, whoa, whoa any opinion would be useless without a history a healthy man of 40 could have a ejection fracture E/F of 66 (mine) it may mean you exercise a lot but are now 65 years oldLVH can be caused when the left side of the heart has to pump against higher systemic pressure - in other words, the "afterload" on the heart is increased (when the aortic valve opens, the pressure is higher than it should be, causing the heart to have to work harder to push blood out of the ventricle and into the aorta). Increased afterload can be caused by aortic stenosis, aortic insufficiency, and hypertension. For example, if you have hypertension (high blood pressure), then the left side of the heart has to work really hard to push blood out and into the systemic circulation. This is one of the reasons that high blood pressure is so bad for you.
When the heart begins to hypertrophy (grow larger), it may dilate, and this enlargement leads to some serious and detrimental effects on its ability as a pump. The way that the heart pumps blood relies on its shape and conductive abilities, and if this changes, then the heart's left ventricle doesn't pump blood as efficiently. This can lead to a reduced ejection fraction (the EF is the amount of blood pumped during systole over the amount of blood that fills the heart at the end of diastole). Normal people GENERALLY have an EF > 0.55, but the cutoff criteria is dependent other variables.
Other diseases of the heart muscle itself can cause LVH (hypertrophic cardiomyopathies - they cause the heart muscle to enlarge). There are many of these, and we don't always know why they happen.
An echo showing LVH and EF of 45% would be best interpreted by your cardiologist. He or she can provide you with a prognosis and a plan of action - because LVH itself is a sign/symptom and not really a disease itself, it will depend on what the ultimate cause of the LVH is. Sorry if that doesn't help very much, but that's all I've got.
Good luck.
