Abstract

OBJECTIVE:

To assess the prevalence, clinical presentation, therapeutic management and medium-term prognosis of spontaneous coronary artery dissection (SCAD).

METHODS:

Over a 5-year period, and out of a cath-lab database of 11,605 files, 23 cases of SCAD were confirmed by re-analysis of angiograms. Therapeutic management and in-hospital outcome were obtained from medical files and prospective follow-up was performed.

RESULTS:

The population consisted of 17 women and 6 men (mean age 45 years). A total of 83% of men had >/=2 cardiovascular risk factors versus only 35% of women (p=0.07). Acute coronary syndrome (ACS) was the clinical presentation in 21 cases (ST+ 61%). The prevalence of SCAD was: 0.2% in the whole population (men: 0.07%, women: 0.6%, p<0.001), and 8.7% and 10.8% in women <50 years with ACS and ST+ ACS, respectively. Left and right coronary arteries were involved in 20 (87%) and 3 (13%) cases, respectively. Coronary stenting alone was performed in 8 (35%), bypass surgery alone in 2 (9%), and both in 3 (13%) cases. Ten patients (44%) were medically managed. One patient died during hospitalization. At 1-year follow-up (100%), 77% of discharged patients were event-free. One patient died, four experienced heart failure, and none had angina or new ACS.

CONCLUSION:

SCAD is observed in as much as 1 out 10 women <50 years presenting with ACS. After immediate coronary angiography, medical therapy is the chosen strategy in half of cases. Most patients who survive the acute phase are free from coronary events at 1 year.
