To research the onset characteristics of angina pectoris（ AP） complicated with atheroscle- rotic thrombotic cerebral infarction（ ATCI）. Methods Totally 982 cases of AP complicated with ATCI were col- lected from May 2009 to July 2010 mainly in Liaoning Province. The gender

age

ethnicity

onset solar terms

diseased parts order

past medical history and common patterns were analyzed. Results There were 525 male patients and 457 female patients aged from 36 to 84 with an average of（ 67. 92 ± 9. 86） years old and 481 patients（ 48. 98%） aged from 60 to 75. There were 964 cases（ 98. 17%） of Han nationality and 17 cases of ethnic minority（ 1. 73%）. There were 407（ 41. 45%） retirees and 328 cases（ 33. 40%） with junior secondary education level. Onset was more common in winter

early spring or late autumn. The top 10 onset solar terms were Light Snow

Minor Cold

Frost Descent

Cold Dew

Vernal Equinox

Start of Winter

Awakening of Insects

Major Cold

White Dew and Start of Spring accounting for 60. 92%（ 598 cases）. The primary disease in most patients was heart disease and 724 cases（ 73. 73%） with hypertension history. The common patterns were phlegm-stasis binding together pattern

qi deficiency blood stasis pattern

wind-phlegm obstructing the network vessels pattern

qi-yin deficiency pattern and wind-phlegm obstructing the network vessels combined with qi-yin deficiency pattern accounting for 44. 91%（ 441 cases）. Conclusion Most of AP complicated with ATCI patients are old and poor ability to adapt with more complications and complex patterns and should be paid more attention to prevention and treatment.
