Disease & more: 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.

Multiple things: Cardiac output is the product of heart rate in stroke volume. Thus, an increase in heart rate results in an increase in cardiac output. Stroke volume can be affected by changes in preload, afterload, and contractility (strength of contraction). Preload is "priming the pump". Afterload is the resistance to ejection during systole (contraction).

Many: High cardiac out put can be from sepsis, thyroid disease, arterial-venous fistulas, anemia, vitamin defiency etc. Low out put can be from a heart attack and a weak heart muscle, virus induced cardiomyopathy, severe valvular heart disease. Just to name a few.

What are factors that influence the cardiac output?

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.

Heart pump volume: The cardiac output is the volume of blood per minute pumped by the heart. Cardiac output is equal to heart rate multiplied by stroke volume (the volume of blood ejected with each heartbeat).
