Purpose: To analyze the basic situation and health related quality of life (HRQOL) results of patients with transient ischemic attack (TIA), and to study the influencing factors of health related quality of life in patients receiving clopidogrel. Method: Divide the TIA patients into clopidogrel group, aspirin group and untreated group. Measure HRQOL scores of TIA patients using the short form 36 questionnaire (SF-36) scale and analyze influencing factors of HRQOL with one-way ANOVA and multivariate stepwise linear regression statistical methods. Results: The differences of HRQOL scores among three groups are of statistical significance (F = 4.29, P = 0.00). There is no difference in HRQOL score between clopidogrel group and aspirin group (t = 5.35, P = 0.00), but HRQOL scores of clopidogrel group and aspirin group are higher than those of the untreated group (t = 6.14, P = 0.00; t = 5.16, P = 0.00). The HRQOL scores of clopidogrel group are positively correlated with diet, exercise, gender and family harmony (P < 0.05), but negatively correlated with diabetes, hypertension, smoking, drinking, hyperlipidemia, age, career and ABCD2 score (P < 0.05). Conclusion: TIA patients who received secondary prevention with clopidogrel and aspirin show better life quality results than those who did not. There were many factors influencing clopidogrel's treatment effect. Paying attention to middle-aged and elderly, the obese, mental workers and female TIA patients, teach TIA patients to quit smoking, drinking and eating low-salt and low-fat food, actively treating their hypertension, hyperlipidemia and diabetes and laying emphasis on psychological counseling and exercise can significantly improve the treatment effect of clopidogrel.
