What are xanthomas? {Ans: Cholesterol deposits along the skin and tendons in extremely elevated hyperlipidemia}What causes cardiogenic shock? {Ans: Myocardial infarction, myocardial contusion, sustained arrhythmias, or cardiac surgery}What is cardiac output? {Ans: The efficiency of the heart's pump is measured by the cardiac output. The cardiac output (CO) is the amount of blood the heart pumps each minute. It is the product of the stroke volume (SV) and the heart rate (HR). CO = SV x HR.}What is preload? {Ans: Preload is the end-diastolic pressure when the ventricle has been filled and represents the volume work of the heart.}What is cardiac contractility? {Ans: Cardiac contractility is the ability of the heart to change its force of contraction without changing its resting (diastolic) length.}What is atherosclerosis and what is it a major risk factor of? {Ans: Hardening of the arteries, hyperlipidemia}
