Canadian Cardiovascular Society Angina Grading Scale
The Canadian Cardiovascular Society Angina Grading Scale is commonly used for the classification of severity of angina:
- Class I – Angina only during strenuous or prolonged physical activity
- Class II – Slight limitation, with angina only during vigorous physical activity
- Class III – Symptoms with everyday living activities, i.e., moderate limitation
- Class IV – Inability to perform any activity without angina or angina at rest, i.e., severe limitation
It is similar to the New York Heart Association Functional Classification of heart failure.

“Beautiful credit! The foundation of modern society. Who shall say that this is not the golden age of mutual trust, of unlimited reliance upon human promises? That is a peculiar condition of society which enables a whole nation to instantly recognize point and meaning in the familiar newspaper anecdote, which puts into the mouth of a distinguished speculator in lands and mines this remark:M”I wasn’t worth a cent two years ago, and now I owe two millions of dollars.””
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“The only phenomenon with which writing has always been concomitant is the creation of cities and empires, that is the integration of large numbers of individuals into a political system, and their grading into castes or classes.... It seems to have favored the exploitation of human beings rather than their enlightenment.”
—Claude Lévi-Strauss (b. 1908)
“The Humanity of men and women is inversely proportional to their Numbers. A Crowd is no more human than an Avalanche or a Whirlwind. A rabble of men and women stands lower in the scale of moral and intellectual being than a herd of Swine or of Jackals.”
—Aldous Huxley (1894–1963)
