Objective: Heart disease is one of the high prevalence diseases which is increasing in both morbidity and mortality. Sensory processing style is a vital factor which has a critical role in learning and ordinary performances. When Sensory processing couldn't recognize a stimulate or couldn't predict it's severity or its time, therefore this will lead to uncertain while about something we are facing to. This is called ambiguity. There are evidences that ambiguity is a powerful stressor. Our goal is to find the relationship between ambiguity tolerance and Sensory processing style and cardio diseases.
Method: The society of this study is the female with cardio disease and our sample is 34 female patient and 34 female without cardio disease as the control group, whom are academic educated with the range of 22 to 59 years old of age.
The Persian version of Ambiguity Tolerance Scale and Sensory processing Scale is used. The analysis process is t-test for independent groups.
Result: The results show that people with heart disease have lower threshold for ambiguity tolerance (P ≤ 0/05) and the styles of sensory processing as Low Registration, Sensation Seeking, Sensory Sensitivity and Sensation Avoiding, in patients is significantly different (P ≤ 0/05) from the women without heart disease.
Conclusion: We have understood that when individual is faced by a combination of unknown and complex stimulates, she will experience ambiguity. And the women who are suffering from cardio disease that are struggling with physical and mental problems have special styles of Sensory processing and also they have lower threshold for ambiguity tolerance.
