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. The tests are similar to those used to evaluate other heart attacks, such as electrocardiograms and blood tests to detect blood damage.
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.
Music of the Classical period roughly covers from 1750 to 1800ish. In comparison with the baroque period (approximately 1600-1750) and Romantic age (basically 19th century; but Post-Romantics went on well beyond), you will see that it covers a relatively short period of time.
