Causes Of Stroke Volume
Stroke volume: Stroke volume is the amount of blood ejected from the heart with each beat. A higher stroke volume implies increased cardiac contractility which means more oxygen demands by the heart muscle. In the presence of significant coronary artery disease, this increased contractility will increase, not reduce, angina. ...Read moreSee 3 more doctor answers
Stroke volume (SV): The left and right sided chambers of your heart are like 2 pumps. All the volume from the first pump should be equal to what's used in the second. Too little blood=anemia, Smaller SV in one pump suggests a leak (shunt) versus bad pump (heart failure). Your body is always fighting to maintain a balance. When balance is disrupted, that is often when you feel ill. ...Read more
Circuits in series: Since the left (systemic) and right (pulmonary) circuits are in series with each other, the blood that each ventricle pumps is the blood that has just come from the other ventricle! now, this is not always true in congenital heart disease where there are connections (shunts) between the two systems. ...Read moreSee 1 more doctor answer

How much would 40 minutes a day exercise increase the overall stroke volume of the heart in 3 months in a male 22?
Stroke volume: 3 months of aerobic exercise as described might make no change in stroke volume, if it did it would be subtle. It takes a long time to begin to see benefits from exercise and usually at least 6 weeks to see anything. Stroke volume would likely take 6mo to a year to measure something real. ...Read more
I have an EF of 48%, and a stroke volume of 46.9 mL, and my cardiologist isn't concerned. I'm 25 years old. I'm super worried, what should I do?
Which value of cardiac output is considered high?My stroke volume 90ml, by 75 bpm, that means cardiac out:6, 7l/min;cardiac index would be 3, 5l/min*m2.Tx
Cardiac Output: Numbers such as you list can be normal especially in a smoker. Numbers alone without clinical correlation don't necessarily mean a lot. You should discuss these data with the physician(s) who know you and your specifics. ...Read more
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. ...Read moreSee 1 more doctor answer
Is my cardiac output too high? Results from echo:stroke volume 100ml, by 70 bpm, that means cardiac out:7l/min; cardiac index would be 3, 57l/min*m2.
