| Popis: | Objective: Our purpose was to determine the prognostic value of vaginal bleeding in early pregnancy outcome as well as to analyze the role of cardiac activity in predicting pregnancy viability in the presence of vaginal bleeding. Study Design: This was a cohort study of pregnancies obtained using either assisted reproductive technology (ART) or routine infertility treatment (RIT). Two hundred twenty-eight pregnant women were divided into two groups based on the presence or absence of vaginal bleeding. Successive measurements of β-hCG levels were obtained every 2 days, starting on day 14 after ovulation or embryo transfer. All pregnancies underwent weekly transvaginal ultrasound (UTZ) examinations beginning on day 21. The occurrence of vaginal bleeding was monitored weekly. Results: Seventy of the 228 patients (31%) had bleeding in early pregnancy, resulting in 31 (44%) pregnancy losses. Only 22 pregnancy losses (14%) were observed in 158 patients who did not have bleeding (P |
