Objective: A small percentage of acute pulmonary thromboembolisms (PTE) persist as chronic fibrin clots, potentially leading to chronic thromboembolic pulmonary hypertension (CTEPH). A scoring system for evaluating the burden of acute PTE based on computed tomography pulmonary angiogram (CTPA) findings was tested for its association with CTEPH within one year.
Material And Methods: In this retrospective cohort of 475 patients with a definitive diagnosis of acute PTE, the Qanadli score (QS) was calculated on the initial CTPA.
Article Synopsis
- Pulmonary endarterectomy (PEA) is a key treatment for chronic thromboembolic pulmonary hypertension (CTEPH), and this study assessed its effectiveness in Tabriz, Iran, over four years.
- The analysis included 42 patients who experienced significant improvements in heart function, pulmonary pressure, and overall endurance, with some complications observed post-surgery.
- The findings suggest that PEA is a safe procedure with low mortality rates and emphasize the need for increased awareness and access to qualified treatment centers for CTEPH patients.

Background: Chronic thromboembolic pulmonary hypertension (CTEPH) is a serious condition that results from incomplete resolution of thromboemboli in pulmonary arteries. Symptomatic patients with chronic thromboembolic disease may have normal hemodynamic at rest. The aim of this study is to evaluate the outcome of pulmonary endarterectomy (PEA) in symptomatic patients with chronic thromboembolic pulmonary disease (CTEPD) in the absence of pulmonary hypertension as currently defined (mean pulmonary artery pressure [mPAP] < 20 mm Hg).

- - The study investigated the incidence of venous thromboembolism (VTE) in COVID-19 patients after they were discharged from the hospital, tracking 1,529 patients for at least 45 days through follow-up calls.
- - Out of those, 228 patients reported potential VTE symptoms, but only one was diagnosed with symptomatic pulmonary embolism (PE), leading to a low rate of symptomatic VTE of 0.2% within the study period.
- - The findings suggest that routine use of extended thromboprophylaxis after hospitalization for COVID-19 may not be beneficial, indicating that further randomized trials are needed to clarify this issue.
Purpose: Chronic thromboembolic pulmonary hypertension (CTEPH) is an important complication after acute pulmonary embolism (PE) with considerable morbidity and mortality. The aim of this study was to estimate the CTEPH incidence in a cohort after the first occurrence of PE.
Methods: We conducted a 1-year follow-up cohort study between 2015 and 2018 to assess the incidence of CTEPH in 474 patients with their first acute episode of PE.
Article Synopsis
- Pulmonary hypertension is a significant complication in patients with thalassemia major, with its prevalence ranging from 2% to 79%, though this study found it to be 4.5% in their sample.
- A total of 70 patients were assessed, excluding those with other heart conditions, and categorized into low, medium, and high risk for pulmonary hypertension based on tricuspid regurgitation velocity (TRV).
- Results indicated that there was no meaningful difference in hemoglobin levels between the high-risk group and others, suggesting further investigation is needed to understand the relationship between blood transfusions and pulmonary hypertension in thalassemia.
