1
Q

What is functional staging of heart disease based on?

A

How the patient feels

2
Q

What are the 2 types of functional classifications?

A

NYHA and ISACHC - patients can move forward OR backward through the classes

3
Q

What is structural staging of heart disease based on?

A

What the heart looks like

4
Q

What is the type of structural staging we use and what is it designed for?

A

ACC/AHA classification (adopted by ACVIM) - patients can only move forward thru classes;

Designed for DMVD

5
Q

What is stage A of HD?

A

NOT actually disease!

Breeds that are at risk but that do not show any signs or structural abnormalities

6
Q

What are the recommendations for patients in stage A?

A

Annual PE and auscultation, CE, no medical tx, no dietary restrictions

7
Q

What breeds are predisposed to HD?

A

Dobermans, Cavalier King Charles Spaniels

8
Q

What is stage B of HD?

A

There is structural disease present, along with a heart murmur OR imaging evidence (echo, xrays);

NO clinical signs!

9
Q

What is stage B1 of HD?

What are the recommendations?

A

No hemodynamic compromise; None-mild heart enlargement

Rec = No medical tx or dietary restrictions, annual monitoring

10
Q

What is stage B2 of HD?

What are the recommendations?

A

Relevant hemodynamic compromise, significant heart enlargement (echo or rads), DMVD - cutoffs for LA and LV size

Rec = ACEi, Pimobendan

11
Q

What is the earliest stage for DCM?

A

B2

12
Q

Why are ACEi and Pimobendan indicated for stage B2?

A

To delay progression to CHF

13
Q

Why are furosemide and spironolactone not indicated for stage B2?

A

There is no evidence of CHF

14
Q

What is stage C of HD?

What are the recommendations?

A

CHF - current or past signs; L-sided = pulm edema, R-sided = cavitary effusions

Rec = Furosemide, Pimobendan, ACEi, spironolactone, dietary Na restriction, +/- others

15
Q

What is stage D of HD?

What are the recommendations?

A

Current or past signs of CHF refractory to “standard tx” (furosemide high-dose, pimobendan, ACEi, spironolactone);

Rec = increase furosemide dose, increase pimobendan dose, amlopidine, hydrochlorothiazide, +/- anti-arrhythmics, +/- sildenafil
