Spontaneous coronary artery dissection (SCAD) Diagnosis. To diagnose spontaneous coronary artery dissection (SCAD), your doctor may review your signs and symptoms, and order several tests.

when did the Classical era start and end. There are actually Classical eras for different types of art, but I'll just deal with music since that's my specialty! The Classical Era in music lasted from 1750 to about the year 1800.
For the first time, during the Classical period most of the important stylistic advances that occurred can be observed most clearly in the instrumental forms: the symphony, concerto, sonata, and in instrumental chamber music (e.g., the Beethoven string quartets).he Classical period itself lasted from approximately 1775 to 1825. The name classical is applied to the period because in art and literature, there was keen interest in, admiration for, and emulation of the classical artistic and literary heritage of Greece and Rome.
