Implications of elevated cardiac troponin in patients presenting with acute pulmonary embolism: an observational study

Despite the contemporary therapeutic advancement, acute pulmonary embolism (PE) remains a leading cause of hemodynamic instability and mortality (1). The important prognostic factors in patient presenting with PE include hemodynamic status and pre-existing comorbidities (2). Notably, the frequency of early deaths in patient with acute PE ranges from 7.9% to 14% (3). However, on initial presentation, it is difficult to distinguish PE from other acute cardiopulmonary disorders due to nonspecific signs and symptoms which might result in delayed or missed diagnosis and inappropriate management (4). Therefore, early diagnosis and risk-stratification of PE necessitate accurate tools which ensure timely and appropriate management (5)
