The YEARS algorithm was successfully developed to reduce the number of computed tomography pulmonary angiography (CTPA) investigations in the diagnostic management of patients with suspected pulmonary embolism (PE), although half of patients still needed to be referred for CTPA. We hypothesized that ECG derived ventricular gradient optimized for right ventricular pressure overload (VG-RVPO), an easy to use tool for detecting PE-induced pulmonary hypertension (PH), may further improve the efficiency of the YEARS algorithm. ⋯ This post-hoc analysis of the YEARS study failed to demonstrate incremental diagnostic value of VG-RVPO for acute PE, either as stand-alone diagnostic test or combined with the YEARS algorithm. Nevertheless, the role of VG-RVPO recorded on admission could potentially be valuable in the risk stratification of PE during hospitalization, although this remains to be studied.

Early risk stratification based on SYNTAX score plays a crucial role to identify the need for early invasive strategy in patients with NSTEMI. The predictive role of frontal QRS-T angle [f(QRS-T)] on the atherosclerotic burden of CAD is less clear in NSTEMI patients. In this study, we aimed to investigate the relationship between f(QRS-T) and SYNTAX score in NSTEMI patients. ⋯ In NSTEMI patients, f(QRS-T) has been found to be a useful decision-making tool to predict SYNTAX score to assess early invasive strategy.
