Pulmonary hypertension (PH) encompasses a broad range of conditions, including pulmonary artery hypertension, left-sided heart disease, and pulmonary and thromboembolic disorders. Successful diagnosis and management rely on an integrated clinical assessment of the patient's physiology and right heart function. Right ventricular (RV) heart failure is often a result of PH, but may result from varying abnormalities in preload, afterload, and intrinsic myocardial dysfunction, which require distinct management strategies.

Article Synopsis
  • In 2019, the BLOCK-COPD study aimed to assess how metoprolol impacts exacerbation risk and mortality in COPD patients without prior beta-blocker indications, hypothesizing that coronary artery calcium (CAC) scores could help predict these outcomes.
  • Researchers analyzed data from 109 participants, measuring their CAC scores and tracking exacerbations over a median follow-up of 350 days, finding a high prevalence of CAD (84% had CAC scores >0) but no strong links between CAC and overall exacerbation risk.
  • However, they did identify significant associations between increased CAC in the left circumflex artery and higher exacerbation risks, suggesting that future studies with larger groups are needed to explore these findings further.

Introduction: Right ventricular dysfunction (RVD) is a key component in the process of risk stratification in patients with acute pulmonary embolism (PE). Echocardiography remains the gold standard for RVD assessment, however, measures of RVD may be seen on CTPA imaging, including increased pulmonary artery diameter (PAD). The aim of our study was to evaluate the association between PAD and echocardiographic parameters of RVD in patients with acute PE.

Objective: Pulmonary infarction is a common clinical and radiographic finding in acute pulmonary embolism (PE), yet the clinical relevance and prognostic significance of pulmonary infarction remain unclear. The study aims to investigate the clinical features, radiographic characteristics, impact of reperfusion therapy and outcomes of patients with pulmonary infarction.

Design, Setting And Participants: A retrospective cohort study of 496 adult patients (≥18 years of age) diagnosed with PE who were evaluated by the PE response team at a tertiary academic referral centre in the USA.

Background: Lactic acidosis is a heterogeneous condition with multiple underlying causes and associated outcomes. The use of multi-dimensional patient data to subtype lactic acidosis can personalize patient care. Machine learning consensus clustering may identify lactic acidosis subgroups with unique clinical profiles and outcomes.
