External validation of the InShape II study algorithm for exclusion of chronic thromboembolic pulmonary hypertension in patients with pulmonary thromboembolism.

BACKGROUND AND AIM: The most severe long-term complication of pulmonary embolism (PE) is chronic thromboembolic pulmonary hypertension (CTEPH), and its early diagnosis often requires numerous diagnostic tests. The InShape II study proposes an early screening algorithm that aims to reduce the number of echocardiographic studies. The objective of our study is to validate this algorithm in our patient cohort. MATERIALS AND METHODS: We retrospectively analyzed patients admitted to Hospital Rey Juan Carlos between November 2017 and February 2020, who were diagnosed with PE based on computed tomography angiography (CTA). Patients were followed for at least one year, and clinical, laboratory, and complementary test data were collected at three months and one year. The InShape II algorithm was applied to these patients to validate its results. RESULTS: During the study period, 236 patients were diagnosed with PE, of which 137 were excluded. The algorithm was validated in 99 patients. Applying the InShape II score, 19 echocardiograms would have been performed (three of them with intermediate-high probability of CTEPH), while 80 echocardiograms would have been avoided (two of them with intermediate-high probability). This yielded a sensitivity of 60% and a specificity of 83% for the score, with an area under the curve (AUC) of 0.715 (95% CI: 0.472-0.958). CONCLUSIONS: Our results support the notion that the InShape II algorithm could be a useful tool for initial screening of CTEPH in low-incidence settings, as it would avoid unnecessary echocardiograms that do not provide additional value.

Retinal vein occlusion. Audit of a specialized care program.

BACKGROUND AND OBJECTIVES: Retinal vein occlusion (RVO) is the second most frequent cause of retinal vascular disease and is related to classic cardiovascular risk factors. A specific program was designed to detect and treat risk factors in patients with RVO. The aim of this study is to audit the results of this program. PATIENTS AND METHODS: The program consisted of a multidisciplinary clinical evaluation by the Ophthalmology and Internal Medicine Departments. All patients with RVO were screened, at minimum, for hypertension, diabetes, dyslipidemia, smoking, overweight, and antiphospholipid syndrome. New risk factors or poor control of known risk factors were expected to be found in at least one-third of the patients. Among them, therapeutic measures were expected to be taken in at least two-thirds. A dissociated automated search of the data of all patients who entered the program between April 2021 and April 2022 was performed. RESULTS: Fifty-six patients were included for analysis. Of these, 39 (69.6%) had at least one new or poorly controlled risk factor and 43 (76.8%) had their treatment modified in some way. Antiphospholipid syndrome was detected in five (8.9%). Only one patient had low-risk hereditary thrombophilia. After an exhaustive examination, no risk factors were found in 11 patients. CONCLUSION: This specific program has been effective in detecting new or poorly controlled risk factors and improving their treatment.

Venous thromboembolism in patients with liver diseases.

Essentials Emerging evidence shows that patients with liver disease are not protected from thrombotic events. We assessed the risk of venous thromboembolism (VTE) in patients with liver disease. The presence of VTE resulted in an increase in mortality for patients with liver disease. Hospitalized patients with moderate-severe liver disease had low risk of VTE during admission. SUMMARY: Background and Aims Patients with liver disease were traditionally believed to be protected against development of blood clots, but some studies have shown a potential increased risk of venous thrombotic complications. We assessed the risk of venous thromboembolism (VTE) in patients with liver disease. Methods Data in discharge reports of patients with liver disease and control patients without liver disease were analyzed from the national inpatient sample. Incidence of VTE was compared in patients with mild, moderate-severe or no liver disease, and the impact on in-hospital mortality and length of stay was calculated. Results The overall incidence of VTE for patients with no liver disease, mild liver disease and moderate-severe liver disease was 2.7, 2.4 and 0.9 per 100 patient discharges, respectively. In the presence of VTE, in-hospital mortality was 10.8%, 5.8%, and 21.7% for the no liver disease, mild disease and moderate-severe liver disease, respectively. The presence of VTE resulted in an increase in mortality for patients with no liver disease (OR, 1.16; 95% CI, 1.14-1.18) and moderate-severe liver disease (OR, 1.63; CI 95%, 1.42-1.88). Conclusions Patients with moderate-severe liver disease have a lower risk of VTE than those without liver disease. Development of thrombosis during admission increased the risk of in-hospital mortality.
