Myocardial infarction documented by hospital summaries, procedure reports,
laboratory reports, etc.
Coronary revascularization documented by physician or procedure report
• Peripheral Vascular Disease demonstrated by:

with asymptomatic carotid disease documented by imaging studies may be included
Peripheral revascularization documented by procedure report
• Cerebrovascular Disease. For example, TIA or stroke without significant
neurological impairment documented by neurological evaluation, procedure
report.

160 mmHg or a diastolic blood pressure greater than 95 mmHg at the Screening or
Baseline visit

significant abnormal laboratory test values:
Subjects with an SGOT (AST) or SGPT (ALT) greater than 1.5 times the upper limit
of normal (ULN) or total bilirubin greater than 1.1 times the ULN
