Angiotensin converting enzyme polymorphism and ischemic stroke

OBJECTIVES: To assess the polymorphism of angiotensin converting enzyme (ACE) in ischemic stroke in an Egyptian sample. METHODS: One hundred subjects (70 ischemic stroke patients, and 30 healthy controls) were included in case control cross sectional study during the period from January 2017 to January 2018, at Neurology Department, Menufia University Hospital, Shibin EL-Kom, Egypt. Patients underwent complete neurological assessment, national institute health stroke scale (NIHSS), and Toast classification. All subjects underwent genotyping of ACE gene polymorphism. RESULTS: There are 42.9% from the patients versus 33.3% from controls showed geno typing of Insertion/Deletion (I/D) and Allele D is more frequent regarding I allele in ischemic stroke patients but this difference did not reach significant level to be risk factor. The I/D polymorphism was the predominant type in SVS and LVS while DD was the predominant type in cardio-embolic one. There were no significant differences between NIHSS in different ACE gene polymorphism. CONCLUSION: In spite of ACE genotyping differences among Egyptian ischemic stroke patients, we cannot consider it a predisposing factor to stroke occurrence or severity.
