CCS & NYHA Classification Systems Flashcards
What is the CCS?
Canadian Cardiovascular Society
What is the CCS classification used to categorize?
The functional severity of angina pectoris
What is the CCS classification based upon?
The ability to perform metabolic events METs
What are the four CCS classifications? and what are their associated METs?
Class I (7-8 METs tolerance)
Class II (5-6 METs tolerance)
Class III (3-4 METs tolerance)
Class IV (1-2 METs tolerance)
What is a CCS class I?
Asymptomatic w/ ordinary physical activity, only symptomatic w/ strenuous physical activity (prolonged exercise)
What is a CCS class II?
Slight limitation
(Asymptomatic when walking more than 2 blocks on level ground and climbing more than 1 flight of stairs)
What is a CCS class III?
Marked limitation
(Symptomatic when walking 1-2 blocks at normal level and/or climbing 1 flight of stairs, but still asymptomatic w/ showering/dressing/making bed/playing golf)
What is a CCS class IV?
Inability to perform any physical activity without discomfort ; anginal symptoms may be present at rest
How does CCS classification correlate to ASA risk?
CCS I -> ASA II
CCS II -> ASA III
CCS III & IV -> ASA IV
What is the NYHA?
New York Heart Association
What is the NYHA classification used to categorize?
The presence of symptoms during activity for patients with CHF
What is CHF?
Congestive heart failure; chronic progressive decrease in the heart’s muscles’ ability to pump blood
What are the four NYHA classifications?
I, II, III, and IV
What is a NYHA class I?
Asymptomatic
(Pt w/ cardiac disease but w/o resulting in limitation of physical activity)
What is a NYHA class II?
Symptomatic with moderate exertion
(Asymptomatic at rest, but ordinary physical activity results in fatigue, palpitation, dyspnea or anginal pain)
