Early recurrence of spontaneous coronary artery dissection: potential association with coronary vasospasm and optimal timing for spasm provocation test-a case series.

ABSTRACT:

Background

Spontaneous coronary artery dissection (SCAD) is an uncommon cause of acute coronary syndrome (ACS). Various factors predispose individuals to SCAD, including coronary vasospasm, which has been identified in some studies as a related factor.

Case summary

We present a series of three cases of ACS attributed to SCAD. Two cases involved early de novo recurrence potentially related to coronary spasm, and one case involved iatrogenic coronary artery dissection during a spasm provocation test.

Discussion

High recurrence rates of SCAD within 30 days of the initial event have been observed, although the effectiveness of pharmacologic therapy has not been conclusively established. While the administration of beta-blockers has been associated with a reduced ri
