TI  - Primary coronary artery dissection: its incidence, mode of the onset and 
      prognostic evaluation.
PG  - 307-17
AB  - The incidence, mode of the onset and prognosis of primary coronary artery 
      dissection in 1,445 consecutive patients with myocardial infarction undergoing 
      coronary angiography were elucidated in the present study. Primary coronary 
      artery dissection was observed in four patients (0.28%). The first case was a 
      28-year-old man, who developed angina at rest, followed by inferior myocardial 
      infarction. His coronary angiogram showed dual lumina in the proximal to distal 
      segments of the right coronary artery, which were separated by a flap. A left 
      ventriculogram showed severe impairment of contraction (akinesis) in its inferior 
      segment. Six years later, he was classified as New York Heart Association (NYHA) 
      functional class I. The second case, a 54-year-old man, developed vasospastic 
      angina followed by inferior myocardial infarction. His coronary angiogram showed 
      a similar dissection from the proximal to distal segments of the right coronary 
      artery. A left ventriculogram showed akinesis of the inferior segment and a 
      coronary angiogram five years later showed marked resolution of the dissection. 
      Twelve years after the infarction, he was classified as NYHA functional class I. 
      The third case, a 46-year-old woman, experienced sudden onset of inferior 
      myocardial infarction. Her coronary angiogram showed dissection from the middle 
      to distal segments, and the posterior descending branch of the right coronary 
      artery. A left ventriculogram showed akinesis of the inferior segment, and three 
      years later, she was asymptomatic. The fourth case, a 28-year-old woman, 
      developed anterior myocardial infarction following delivery. Her coronary 
      angiogram revealed dissection from the proximal to middle segments of the left 
      anterior descending artery. A left ventriculogram showed akinesis in the 
      anteroseptal segment and dyskinesis in the apical segment. She died suddenly four 
      years after her myocardial infarction. Thus, primary coronary artery dissection 
      is not extremely rare and it may have been associated with coronary vasospasm in 
      at least two of these four cases.
