Abstract:

Based on basic pathological changes, the acute onset of stroke is often triggered by various inducing factors of daily life. The onset of stroke is usually unexpected, but relevant mechanisms are not clear. Currently, most studies in China focus on the relationship between events and the stroke by the case control method. However, systematic qualitative and quantitative studies on inducing events and thorough investigation and analysis of relevant factors are lack. This paper reviews common inducing factors and possible mechanisms of acute onset of stroke according to studies from home and abroad, provides theoretical evidences for identifying inducing factors of acute onset of stroke by introducing the case-crossover study, and provides methods for quantitative analysis of acute onset of stroke.

Key words: stroke, trigger, case-crossover study
