چکیده

BACKGROUND: Acute pulmonary thromboembolism (PTE) is a common disease with a high mortality rate, and a variable and nonspecific clinical presentation. To detect the nonspecific signs and symptoms associated with this condition, several right ventricular (RV) echocardiographic parameters have been proposed as practical marker.METHODS: This cross-sectional study was performed on ۹۳ patients with PTE diagnosed by computed tomography (CT) angiography, and ۵۷ patients with negative PTE based on CT angiography. During the experiment, all patients underwent both transthoracic echocardiography (TTE) and multi-slice CT pulmonary angiography. Transthoracic echocardiography measurements were obtained as patients went through both experimental procedures. These measurements were later compared between the patients with and without PTE.RESULTS: Tricuspid annulus plain systolic excursion (TAPSE) (۱.۶۵ ± ۰.۰۹ vs. ۲.۰۰ ± ۰.۰۸ cm, P < ۰.۰۰۱) and left ventricular (LV) end-diastolic diameter (۴.۵۴ ± ۰.۲۶ vs. ۵.۴۰ ± ۰.۲۴ cm, P < ۰.۰۰۱) were significantly lower in patients with PTE as compared to patients without it. Whereas, RV end-diastolic and end-systolic diameters at the papillary muscle levels (۳.۴۱ ± ۰.۰۹ vs. ۳.۰۲ ± ۰.۱۲ cm, and ۲.۴۸ ± ۰.۰۸ vs. ۲.۱۶ ± ۰.۰۶ cm, respectively, P < ۰.۰۰۱ for both), and tricuspid valve (TV) annulus tissue Doppler imaging (TDI) measurements (۶.۰۲ ± ۰.۱۰ vs. ۵.۷۸ ± ۰.۱۴, P < ۰.۰۰۱) were significantly greater in patients with PTE. On the other hand, no significant difference was found between the two groups of patients regarding pulmonary artery pressure (PAP) (P = ۰.۴۱۶), and RV fractional shortening (P = ۰.۱۵۷). Moreover, our results indicated that RV/LV (cut-off point: ۰.۶۸۹۸) had high sensitivity (۹۳.۵%), specificity (۱۰۰%), positive predicting value (PPV) (۱۰۰%), and negative predicting value (NPV) (۹۰.۴%) in diagnosing PTE.CONCLUSION: TTE may be valuable as a substitute diagnostic method for patients with PTE. This technique may also assist in detecting the severity of the illness, by evaluating RV/LV in cut-off point of ۰.۶۸۹۸.

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
