Heart Failure Flashcards
What are the types of HF?
Left sided HF
Right sided HF ( R Ventricle responsible pump bl lungs& collect 02
DHF
SHF
Causes of HF?
coronary artery disease
Cardiomyopathies
Infection/ viral- myocarditis
Valve disease
Electrical issues
How many deaths associated with a) Cvd, b) HF?
A) 18.5 millon
b) almost 700,000
What are the main risk factors of HF?
^BP, smoking, ^BS, obesity, stress
What are the 2 main types 0f ventricular dysfunction?
- Systolic dysfunction
- Diastolic dysfunction
Systolic BP relates to?
Inadequate contractile function
Diastolic dysfunction relates to?
Impaired relaxation caused by muscle stiffness.
Inflexibility of the heart ventricles from filling completely causing bl to back up in the organs
What is a common features of both systolic & diastolic dysfunction?
Insufficient cardiac output to meet the demands of the body = HF
HF is when ?
Insufficient cardiac output to meet the demands of the body
What are the primary risk factors of HD
Hypertension, diabetes, obesity
What does HFpEF stand FOR?
Heart failure with preserved ejection fraction
Systolic dysfunction is related to enlarged ventricles. Hoe much blood can it pump ?
Less than 40-50%
Diastolic dysfunction is related to stiff ventricles. How much blood can it pump ?
60%
What does NYHA classifications stand for?
New York heart association classifications ( stages of HF)
How many stages in nyha classifications
4
75% of patient with HF have what risk factor?
Hypertension
What age is your risk increased?
40
What BP reading doubles your risk of hf ?
160/ 90mmHg
Ventriclar dysfunction compensation results in symptoms sob is a feature of congestive hf. This results in?
Compensatory mechanism to maintain stroke vol.
Compensatory mechanism to maintain stroke vol. What is linked to this
Renal failure,
Renin angiotention aldosterone system = regulate bl vol, electrolyte bal
HF & RF are linked?
Reduced cardiac performance ( neurphormonal activation, inflammation, oxidative stress)
