Ef is 48% without dilation and normal dimensions. stroke volume low. how possible with normal structure? recheck confirmed it. i'm 25, confused.

LVEF is 48% without dilation: Yes , the LVEF is diminished, normal is 55-70%. Did you drink in the past?, smoker?, what is your weight, and your height, have you had multiple viral infections, family history of heart failure ( mother, father, uncles, grand-parents, brothers etc), The condition is called "cardiomyopathy". The different types of the disease have different causes, signs and symptoms, and outcomes. Cardiomyopathy can be acquired or inherited. "Acquired" means you aren't born with the disease but you develop it due to another disease, condition, or factor. "Inherited" means your parents passed the gene for the disease on to you. In many cases, the cause of cardiomyopathy isn't known. Cardiomyopathy can affect people of all ages. However, certain age groups are more likely to have certain types of cardiomyopathy. This document focuses on cardiomyopathy in adults. Some people who have cardiomyopathy have no signs or symptoms and need no treatment. For other people, the disease develops rapidly, symptoms are severe, and serious complications occur. Treatments for cardiomyopathy include lifestyle changes, medicines, surgery, implanted devices to correct arrhythmias, and a nonsurgical procedure. These treatments can control symptoms, reduce complications, and stop the disease from getting worse. Dilated cardiomyopathy is the most common type of the disease. It mostly occurs in adults aged 20 to 60. Men are more likely than women to have this type of cardiomyopathy. Dilated cardiomyopathy affects the heart's ventricles and atria. These are the lower and upper chambers of the heart, respectively. The disease often starts in the left ventricle, the heart's main pumping chamber. The heart muscle begins to dilate (stretch and become thinner). This causes the inside of the chamber to enlarge. The problem often spreads to the right ventricle and then to the atria as the disease gets worse. When the chambers dilate, the heart muscle doesn't contract normally. Also, the heart can't pump blood very well. Over time, the heart becomes weaker and heart failure can occur. Symptoms of heart failure include fatigue (tiredness); swelling of the ankles, feet, legs, and abdomen; and shortness of breath. Dilated cardiomyopathy also can lead to heart valve problems, arrhythmias, and blood clots in the heart.
