In the determination of cardiac output, the substance most commonly measured is the oxygen content of blood thus giving the arteriovenous oxygen difference, and the flow calculated is the flow across the pulmonary system. This gives a simple way to calculate the cardiac output: [citation needed]
Major factors influencing cardiac output – heart rate and stroke volume, both of which are variable. [1]In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols , ˙, or ˙, [2] is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single ventricle of the heart, per unit time (usually measured ...
Cardiomyopathy and heart failure cause a reduction in cardiac output, whereas infection and sepsis are known to increase cardiac output. Hence, the ability to accurately measure CO is important in physiology, as it provides for improved diagnosis of abnormalities, and can be used to guide the development of new treatment strategies.

Per the American Heart Association (AHA), alcohol is one of the leading causes of dilated cardiomyopathy. [2] However, multiple longitudinal studies have shown a paradoxical lowering of dilated cardiomyopathy with modest-to-moderate alcohol consumption. [2] ACM is a type of heart disease that occurs due to chronic alcohol consumption.
Men who had high alcohol intake (defined as 15 or more drinks per week) were 33% more likely to develop heart disease compared with men who had moderate intake, or three to 14 drinks a week.
Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...
