Presentation and therapy of XXXX and comparisons of postpartum versus nonpostpartum cases.

@entity1 @entity455 @entity101 @entity13865 @entity1188
Predisposing risk factors, clinical course, and prognosis of @entity13865 ( @entity13865 ) remain poorly understood. We reviewed medical records and coronary angiograms of @entity1 admitted to our institution with the diagnosis of @entity13865 from 1999 through 2010. A definite diagnosis of @entity13865 required the agreement of 2 blinded board-certified interventional cardiologists who reviewed all images separately. Baseline characteristics of @entity1 (n = 23) included mean age 45    11 years, female gender in all (100%), history of @entity101 in 13 (57%), and postpartum in 7 (30%). Eleven (48%) had ST-segment elevation on initial electrocardiogram. @entity13865 involved the left main in 5 @entity1 (21.7%), left anterior descending coronary artery in 16 (70%), left circumflex coronary artery in 8 (35%), and right coronary artery in 6 (26%). Four @entity1 (17%) underwent coronary stenting and 6 (26%) required urgent bypass surgery. Comparison between postpartum and nonpostpartum @entity1 revealed significant differences in mean peak troponin levels: 50    34 ng/ml vs 21    23, p = 0.04, mean left ventricular ejection fraction: 34    6% vs 49    9, p <0.01, proximal coronary segment distribution: 6 (86%) vs 3 (19%), p = 0.004, and left anterior descending coronary artery distribution: 7 (100%) vs 9 (56%), p = 0.04, respectively. Repeat coronary angiographies were performed in 11 @entity1 (46%) during a mean follow-up of 39    38 months and 10 (91%) were found to have healed @entity13865 , including those who had undergone bypass surgery. In conclusion, our @entity1 with @entity13865 were characterized by female gender, absence of coronary risk factors, and a high rate of @entity455 without residual stenosis. Larger @entity1188 was found in postpartum @entity1 .
