Classification of Angina
Classification of Angine according to the Canadian Cardiovascular Society.
Stable Angina
Class 1: No limitation: Ordinary physical activity does not cause angina such as walking or climbing stairs. Angina with strenuous or rapid or prolonged exertion at work or recreation
Class 2: Slight limitation of ordinary activity. Walking or climbing stairs rapidly, walking uphill, climbing stairs or after meals or in cold weather, wind, under emotional stress or pain during the first hrs.
after waking up. Walking more than 2 blocks on the level or climbing more than one flight of stairs at a normal pace in normal conditions.
Class 3: Marked limitation or ordinary activity. Walking one to two blocks on the level and climbing one flight of stairs in normal
conditions and at a normal pace.
Class 4: Inability to carry on any physical activity without
discomfort. Symptoms of angina are present even at rest.
Unstable Angina
Class I: New onset, severe or accelerated angina. Subjects with angina of less than 2 months duration. Severe or occurring three or more times per day. Angina that is distinctly more frequent and precipitated by distinctly less exertion. No rest pain in the last 2 months.
Class II: Angina at rest, subacute. Subjects with one or more
episode of angina at rest during the preceding month but not within the preceding 48 hrs.
Class III: Angina at rest, acute. Subjects with one or more
episodes of angina at rest within the preceding 48 hrs.
Clinical Circumstances
Class A: secondary unstable angina. A clearly identified condition extrinsic to the coronary vascular bed that has intensified myocardial ischemia e.g. anemia, fever, infection, hypotension, tachyarrhythmia, thyrotoxicosis
Class B: Primary unstable angina
Class C: post infarction unstable angina (within 2 weeks of MI)
To do before de-stubbing
- What is the relevance of this? I took it from the paper manual, but it does not say there why included. Dx coding? APACHE II Chronic entry? The relevance is for all of these things.--LKolesar 21:24, 15 May 2008 (CDT)
- provide better reference - the Canadian Cardiovascular Society website only has some of this at best.
