1

What is functional staging of heart disease based on?

How the patient feels

2

What are the 2 types of functional classifications?

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

3

What is structural staging of heart disease based on?

What the heart looks like

4

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

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

Designed for DMVD

5

What is stage A of HD?

NOT actually disease!

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

6

What are the recommendations for patients in stage A?

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

7

What breeds are predisposed to HD?

Dobermans, Cavalier King Charles Spaniels

8

What is stage B of HD?

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

NO clinical signs!

9

What is stage B1 of HD?

What are the recommendations?

No hemodynamic compromise; None-mild heart enlargement

Rec = No medical tx or dietary restrictions, annual monitoring

10

What is stage B2 of HD?

What are the recommendations?

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

Rec = ACEi, Pimobendan

11

What is the earliest stage for DCM?

B2

12

Why are ACEi and Pimobendan indicated for stage B2?

To delay progression to CHF

13

Why are furosemide and spironolactone not indicated for stage B2?

There is no evidence of CHF

14

What is stage C of HD?

What are the recommendations?

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

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

15

What is stage D of HD?

What are the recommendations?

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
