Khảo sát các chỉ số đồng bộ cơ học thất trái bằng GSPECT MPI trên người Việt Nam không có bệnh tim mạch
Tóm tắt
Mục tiêu:Xác định giá trị bình thường của các chỉ số đánh giá rối loạn đồng bộ thất trái bằng xạ hình tưới máu cơ tim có gắn cổng điện tim (GSPECT).
Phương pháp nghiên cứu: Mô tả cắt ngang.
Kết quả: 59 đối tượng không có bệnh tim mạch được đưa vào nghiên cứu với tuổi trung bình 58 ± 7,6, nam giới chiếm 72,9%. Chỉ số PSD trung bình là 14,9 ± 2,83, HBW là 42,9 ± 7,07, HK 15,6 ± 4,43 và HS 4,0 ± 0,64. PSD và HBW đều có tương quan tuyến tính với chỉ số Ts-SD12 hình ảnh đồng bộ mô(TSI) với R lần lượt là 0,75 và 0,61.
Kết luận:Giá trị bình thường của các chỉ số đánh giá rối loạn đồng bộ thất trái bằng GSPECT trên đối tượng người Việt Nam trong nghiên cứu tương tự như trên một số chủng tộc khác và có tương quan với chỉ số đánh giá rối loạn đồng bộ bằng TSI
