Many factors: Congenital heart disease, vitamin b1 defiency, anemia, thyroid problem, renal disease, liver disease, brain disease, vascular disease, blood disease, atherosclerosis, valve disease - these are the biggest influencers of cardiac output.

Cardiac output: Stroke volume times heart rate equals cardiac output. Stroke volume relates to myocardial contractility, vascular resistance, vascular volume, anemia and metabolic state. There are subcomponents to all of these.

Cardiac output: In strict physiologic terms, cardiac output is determined by something called stroke volume and heart rate. Heart rate is self-explanatory. Stroke volume is the amount of blood that the heart pumps out with each beat. This in turn is dependent on blood pressure, total blood volume, and how strong the heart contracts.

Dr. Rajat Jhanjeeanswered

Heart rate, volume: Cardiac output is affected by heart rate and the volume of blood pumped out of the heart in each heart beat (stroke volume). Factors that increase the heart rate (anxiety, fever, walking) increase cardiac output. Similarly, factors that increase volume of blood that heart pumps with each cycle increase cardiac output. High level athletes have very high stroke volume, because of conditioning.
