May warrant closer post-angioplasty monitoring in unstable angina or Type 2 lesions; leaves open independent prediction and needs prospective validation.
Does unstable angina and Type 2 lesion morphology predict early sudden coronary artery occlusion following angioplasty in patients with coronary artery disease?
Patients with unstable angina and complex (Type 2) coronary lesion morphology are at a significantly higher risk of experiencing early sudden vessel occlusion following coronary angioplasty.
Buchalter et al. (1992) studied this question.
