What is Heart Failure?
complex clinical syndrome that can result from any structural or functional cardiac disorder that impairs the ability of the ventricle to fill with or eject blood
Describe the difference between diastolic and systolic dysfunction.
The difference between the ability of the ventricle to fill with (dia) or eject (sys) blood.
What is a P-V loop (ventricular used to determine?
cardiac performance (e.g. preload, afterload, contractility, HR)
Describe the difference between Acute and Chronic HF.
Rapid onset of symptoms/signs secondary to abnormal cardiac function; with or w/o previous cardiac disease; often life-threatening, requires urgent treatment
HF is increasing in prevalence with many risk factors. Risk increases with increasing ?
advancing age
Describe the different clinical presentation of Right vs. Left HF.
Right: hepatomegaly, cyanosis, JVD, ascites, edema;
Left: dyspnea, orthopnea, pulmonary congestion, no elevation of venous pressure
B-Type natriuret Peptide is a new marker in HF. It is activated in response to what?
Endogenous peptidde is activated in Ventricular volume/pressure expansion
What is the most common etiology of Heart Failure?
Coronary artery disease (2/3)
Name some nonpharmacological therapies for HF.
Diet, fluids, weight monitoring, execercise, lipid decrease, smoking cessation, DM & HTN control.
Name 3 Drugs that have proven survival benefit in HF.
ACE inhibitors (ARB/ Nitrates); Beta - Blockers; aldosterone antagonists
TRUE/FALSE - Neurohormonal drugs save lives in HF because of the imbalance between the activation and effects of vasoconstrictor and vasodilator hormones.
True
Inotropes can improve symptoms in HF by increasing contractility (Ca), but what negative is associated with this class of drugs?
Proarrhythmic (can increase/hasten mortality)
