What Are Signs Of High Cardiac Output
Varies: Assuming a true high cardiac output syndrome, patients may feel flushed with a fast heart rate. Most are transient situations, but some illnesses and conditions may cause a sustained high output state, e.g., hyperthyroidism, anemia, arterio-venous malformations (congenital or acquired low resistance connections between arteries and veins), or disease like paget's. Requires confirmation by doctor. ...Read moreSee 1 more doctor answer
Low cardiac output: Cardiac output depends on heart rate and stoke volume. Therefore, the cardiac output increases when heart rate goes up in normal heart. However, when the heart is failing the stroke volume is lower as well as the cardiac out which is called heart failure . Sometimes, heart failure could occur when cardiac output is high due to other medical problems such as a severe anemia , hyperthyroidism, etc ...Read more
Can being a prior endurance athlete (but not currently trained) permanently affect cardiac output resulting in high numbers when all else is normal?
Athletic Heart: Interesting question! former athletes have been shown to have more left ventricular hypertrophy or thickened hearts that usually lessens with age and deconditioning. A thick heart can lead to poor heart filling by increased stiffness. A condition called diastolic dysfunction. This can lead to a type of congestive heart failure if it persists. Controlling hr and BP via meds can help. ...Read more
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
