Flashcards in Cardiac Deck (513)
Peptide secreted by ventricles of the heart in response to excessive stretching of the heart muscles
Brain Natriuretic Peptide
What controls the modulation of BNP?
In a heart failure patient, what would the BNP levels look like?
System that regulates blood pressure and water balance
Renin Angiotension Aldosterone System
The volumetric fraction of blood pumped out of the ventricle with each heartbeat or cardiac cycle
What is a normal ejection fraction?
What is the danger level of ejection fraction?
The volume of blood pumped from one ventricle with each beat
The stoke volume of the heart increases in response to an increase in the volume of blood filling the heart when all other factors remain constant
The intrinsic ability of the heart to squeeze; the potential of the myocyte to contract
What is the most accurate measure of how a heart patient is doing?
Pressure needed to open the aortic valve
Myocardial fiber stretch, determined by the amount of blood at the end of diastole and by the pulmonary system
The resistance against which the left ventricle must eject its load
High density lipoproteins that enable the transportation of lipids such as cholesterol
Low density lipoproteins that enable the transportation of lipids such as cholesterol
Stretching the heart too much will cause it to explode
What is the good cholesterol?
What should the HDL levels be?
Greater than 40
What should the LDL levels be?
Less than 100
Occurs when the kidneys leak small amounts of albumin in the urine indicating protein breakdown and heart disease?
Glycerol and a three fatty acid chain that help enable the bidirectional transference of adipose fat and blood glucose from the liver
What should triglyceride levels be?
Lower than 150
Protein produced by the liver that rises when there is inflammation throughout the body, especially in the heart
A non-protein amino acid which high levels of are linked to cardiovascular disease
What is the left atrial valve?
What is the normal stroke volume?
What is the formula for cardiac output?
CO = HR x SV
What is the normal cardiac output?
