Table 2. Presenting symptoms and clinical features.
Relevant clinical and laboratory data in the emergency department at the time of presentation with PE. Continuous variables are presented as mean ± SEM and differences between groups evaluated by the student’s t-test. Dichotomous variables are presented as frequencies (% of population) and differences between groups were evaluated by Chi-square. DVT = deep venous thrombosis. NTproBNP = N-terminal-pro brain natriuretic peptide.
