1
Q

What are the goals of therapy for HFpEF

A
  • Reduce HF symptoms
  • Increase functional status (NYHA class)

A
  • AMI
  • End-stage severe cardiomyopathies

  • Stress cardiomyopathy

  • Secondary to medications
  • Posttraumatic
120
Q

What is the pathophysiology of cardiogenic shock?

A
  • Principle feature = hypotension with evidence of end-organ hypoperfusion
  • Low cardiac output –> sympathetic stimulation –> tachycardia and increased myocardial contractility and peripheral vasoconstriction
121
Q

What is the classic presentatio of a cardiogenic shock patinet?

A
  • Peripheral vasoconstriction (cool, moist skin) and tachycardia
122
Q

What are diagnostic labs in cardiogenic shock?

A
  • Elevated cardiac enzymes (if MI)
  • Elevated CR, ALT, AST (in renal and hepatic hypoperfusion)
  • Coag abnormalities (in hepatic congestion/hypoperfusion
  • Anion gap acidosis and/or serum lactate elevation
  • BNP (for degree of fluid overload
123
Q

What are imaging studies for cardiogenic shock?

A
  • EKG for underlying cause (MI, arrhythmia)
  • Stat transthoracic echo
  • CXR for cardiomegaly, pulmonary congestion
124
Q

What procedures can be considered for management of cardiogenic shock?

A
  • UA with insertion of foley catheter for UO measurement
  • +/- pulmonary artery catheter placement (if diagnosis questionable, pt on inotropes/pressors, or patient not responding to treatment)
  • +/- left heart catheterization
  • Pulmonary capillary wedge pressure with Swanz Ganz catheter: if elevated, supports pulmonary edema diagnosis
125
Q

What is the treatment of cardiogenic shock?

A
  • Oxygen supplementation; intubation, ventilation
  • Vasopressors/inotropes
  • +/- intra-aortic balloon pump
  • Suspected MI –> ASA, Heparin, urgent cath, revascularization
126
Q

what should you consider with vasopressors/inotropes in cardiogenic shock?

A
  • IV fluids arterial line and pulmonary artery catheter insertion to guide management
  • correct underlying causes of acidemia
127
Q

What is the function of inotropic/vasopressor agents in cardiogenic shock?

A
  • Increase contractility of heart, HR, and peripheral vascular tone
  • Can also increase myocardial oxygen demand
128
Q

What should you keep in mind when using inotropic/vasopressor agents?

A
  • beta agonists can precipitate tachyarrhythmias
  • alpha agonists can lead to dangerous vasoconstriction and ischemia in vital organ beds
  • attention should be given to patient as whole not desired arterial pressure
129
Q

What are the inotropic/vasopressor agents used in cardiogenic shock?

A
  • Dopamine
  • Dobutamine
  • Norepinephrine
130
Q

How does dopamine work as an inotropic/vasopressor agent?

A
  • Catecholamine with varying effect at different doses
  • Low doses: dilate renal arterioles/vascular bed
  • Intermediate doses: B1 receptor stimulation and enhanced myocardial contractility
  • High doses: alpha receptor stimulation in addition to B1 stimulation and tachycardia
131
Q

What is the MOA of dobutamine?

A

Strong B1 and weak B2 effects resulting in increased cardiac output, blood pressure, and heart rate, decreased peripheral vascular resistance

132
Q

What are the 2 ways dobutamine differs from dopamine?

A
  • Does not cause renal vasodilation
  • Stronger B2 effect
133
Q

What is the MOA of norepinephrine (Levophed)?

A
  • Strong B1 and alpha-adrenergic effects and moderate B2 effects
  • Increases CO and HR, decreases renal perfusion, decreases peripheral vascular resistance
  • BP effects vary
134
Q

How is norepinephrine usually used?

A

Typically added to dopamine if patient still hypotensive

135
Q

How do you choose a inotropic/vasopressor agent?

A
  • Choose based on need, while looking at HR, MAP, and patient clinical status
  • Titrate single agent to max tolerate dose before adding additional agent
  • Most should be administered through a central line because peripheral extravasation into surrounding tissue can lead to vasoconstriction and skin necrosis
136
Q

What are the 2 circulatory support devices used in cardiogenic shock?

A
  • Intra-aortic balloon pump and left-ventricular assist device (LVAD)
137
Q

How is intra-aortic balloon pump used in cardiogenic shock?

A
  • Temporary support system
  • Patient anticoagulated with IV heparin due to risk of thrombosis
  • Benefits of decreased afterload without increases in myocardial demand
138
Q

How is Left-ventricular assist device usually used in cardiogenic shock?

A

As bridge to cardiac transplant
