Background: Chronic obstructive pulmonary disease (COPD) has significant systemic manifestations, including cardiovascular morbidity. The main aim of our study was to evaluate the effect of short-term COPD treatment with tiotropium/olodaterol (TIO/OLO) 5/5 μg on cardiac function and autonomic integrity. Methods: Twenty-nine patients with newly diagnosed moderate-to-severe COPD were enrolled. We performed pulmonary function tests, cardiac magnetic resonance, cardiac 123I-metaiodobenzylguanidine (123I-MIBG) imaging and analysis of blood biomarkers on our study subjects. The correlations between the tests’ results were evaluated at baseline. The changes in pulmonary and cardiac parameters from baseline through 12 weeks were assessed. Results: Significant associations between pulmonary function tests’ results and high-sensitivity C-reactive protein (hs-CRP), as well as interleukin-22 (IL-22), were observed at baseline. Treatment with TIO/OLO significantly improved lung function as measured by spirometry and body plethysmography. Moreover, we found that the cardiac index increased from 2.89 (interquartile range (IQR) 1.09) to 3.21 L/min/m² (IQR 0.78) (p = 0.013; N = 18) and the late heart-to-mediastinum ratio improved from 1.88 (IQR 0.37) to 2 (IQR 0.41) (p = 0.026; N = 16) after 12 weeks of treatment. Conclusions: Treatment with TIO/OLO improves lung function and positively impacts cardiac function and autonomic integrity, suggesting that dual bronchodilation might have a potential in decreasing the risk for cardiac events in COPD. Hs-CRP and IL-22 might be beneficial in determining the intensity of systemic inflammation in COPD. Further research with a larger cohort is needed to enhance the initial results of this study.

Background and Objectives: The management of patients with pulmonary hypertension (PH) poses a considerable challenge. While baseline cardiac magnetic resonance imaging (cMRI) indices are recognized for survival prognosis in PH, the prognostic value of one-year changes in biventricular mechanics, especially as assessed using feature tracking (FT) technology, remains underexplored. This study aims to assess the predictive value of one-year change in cMRI-derived biventricular function and mechanics parameters, along with N-terminal pro-brain natriuretic peptide (NT-proBNP) levels and six-minute walking test (6MWT) results for three-year mortality in precapillary PH patients. Materials and Methods: In this retrospective study, 36 patients diagnosed with precapillary pulmonary hypertension (mPAP 55.0 [46.3–70.5] mmHg, pulmonary capillary wedge pressure 10.0 [6.0–11.0] mmHg) were included. Baseline and one-year follow-up cMRI assessments, clinical data, and NT-proBNP levels were analyzed. FT technology was utilized to assess biventricular strain parameters. Patients were categorized into survival and non-survival groups based on three-year outcomes. Statistical analyses, including univariate logistic regression and Cox regression, were performed to identify predictive parameters. Results: The observed three-year survival rate was 83.3%. Baseline right ventricle (RV) ejection fraction (EF) was significantly higher in the survival group compared to non-survivors (41.0 [33.75–47.25]% vs. 28.0 [23.5–36.3]%, p = 0.044), and values of ≤32.5% were linked to a 20-fold increase in mortality risk. RV septum longitudinal strain (LS) and RV global LS exhibited significant improvement over a one-year period in the survival group compared to the non-survival group (−1.2 [−6.4–1.6]% vs. 4.9 [1.5–6.7]%, p = 0.038 and −3.1 [−9.1–2.6]% vs. 4.5 [−2.1–8.5]%, p = 0.048, respectively). Declines in RV septum LS by ≥2.95% and in RV GLS by ≥3.60% were associated with a 25-fold and 8-fold increase in mortality risk, respectively. Conclusions: The decrease in right ventricular septal and global longitudinal strain over a one-year period demonstrates a significant predictive value and an association with an increased three-year mortality risk in patients with precapillary PH.

Background and Objectives: Dual bronchodilation in chronic obstructive pulmonary disease (COPD) has demonstrated beneficial effects on health-related quality of life (HRQoL) and exercise-related outcomes. Real-world evidence in treatment-naïve COPD remains limited. Materials and Methods: Forty-six COPD patients and 23 age-, gender-, BMI-, and cardiovascular comorbidity–matched controls underwent spirometry, plethysmography, symptom-limited incremental cardiopulmonary exercise testing (CPET), and the 36-item Short-Form Health Survey (SF-36). Following baseline assessment, COPD patients received tiotropium/olodaterol as part of routine practice. Thirty-two patients underwent repeated examinations at 12 weeks. Baseline differences between the COPD and control groups were assessed, and longitudinal changes in pulmonary function, CPET, and SF-36 were evaluated in COPD patients. Results: Compared with controls, COPD patients had lower peak oxygen uptake (VO₂; 17.4 ± 4.4 vs. 22.8 ± 4.5 mL/kg/min, p < 0.001) and oxygen pulse (11.5 ± 3.5 vs. 14.0 ± 2.4 mL/beat, p = 0.003), failed to reach 80% of predicted values, and exhibited worse ventilatory efficiency (p < 0.001). SF-36 scores in the COPD group were lower across all domains. After 12 weeks of tiotropium/olodaterol, pulmonary function improved significantly. CPET was performed at comparable efforts at both visits. Peak VO₂ increased from 70 ± 15 to 75 ± 16% predicted (p = 0.044), and peak oxygen pulse from 74 ± 16 to 79 ± 16% predicted (p = 0.015). VE/MVV decreased from 0.77 ± 0.23 to 0.69 ± 0.15 (p = 0.03). Higher baseline VE/MVV predicted a larger improvement after treatment (B = 0.71, p < 0.001), while beta-blocker use had no effect on the change of VE/MVV. SF-36 physical functioning and health change scores improved (both p < 0.01). Conclusions: At diagnosis, COPD was associated with impaired exercise physiology and reduced HRQoL. Dual bronchodilation improved exercise responses and perceived physical functioning. Beta-blocker use was not associated with changes in breathing reserve, supporting the use of cardioselective agents when indicated.

Background/Objectives: Since 2015, pulmonary arterial hypertension (PAH)-specific medications have been fully reimbursed in Lithuania. To describe the current situation of PAH treatment in the country and to determine survival during different PAH treatment regimens. Methods: The data from the Institute of Hygiene and the State Data Agency of Lithuania cases with administrative codes I27.0 and I27.8 have been evaluated. Results: In 2025, 225 confirmed cases of PAH were treated with PAH-specific medications in two PH centers. At least one PAH-specific medication was prescribed to 163 (72.4%) female and 62 (27.6%) male patients. Among these, 96 (42.7%) received sildenafil monotherapy, 82 (36.4%) received a combination of sildenafil and an ERA, 36 (16.0%) were on triple PAH-specific therapy (including selexipag or treprostinil), and 11 (4.9%) received other regimens due to specific medical considerations. The age of adults treated with sildenafil monotherapy vs. other therapies was 63.9 ± 14.8 (n = 117) and 51.5 ± 17.3 (n = 116) years, respectively (p < 0.05). A total of 191 PAH patients who received targeted therapy died during the observational period 2017–2025. Of these, 105 received monotherapy, 57 sildenafil and endothelin receptor antagonist and 29 triple therapies (treprostinil [n = 19], selexipag [n = 6], or inhaled iloprost [n = 4] were prescribed as the third drug). Patients who died and received triple therapy were younger than those on mono- and dual therapy (age at diagnosis 45.0 ± 21.6, 67.2 ± 14.7 and 61.6 ± 16.3 years, respectively, p < 0.01). Survival was longer in patients on dual therapy compared with monotherapy (43.1 ± 28.1 vs. 31.7 ± 25.0 months, p = 0.04), and the longest was in those receiving triple therapy (59.9 ± 29.4 months; p < 0.05). Conclusions: The availability of reimbursed medications dramatically increased the number of treated PAH cases in Lithuania. In 2025, most of the PAH patients received sildenafil monotherapy. Patients treated with sildenafil only were significantly older than the rest of cohort. In the survival analysis, combination PAH therapies were more often prescribed to younger patients and were associated with longer duration of life than monotherapy.

Background/Objectives: Quantitative computed tomography (CT) can be used to characterize airway responses to therapies for chronic obstructive pulmonary disease (COPD), but prospective real-world data in treatment-naïve patients remain limited, and the role of inflammatory markers as potential predictors of structural airway response is poorly understood. Methods: We conducted a prospective real-world study in treatment-naïve patients with moderate-to-severe COPD (n = 47). Lung function and chest CT were assessed at baseline and after 12 weeks of tiotropium/olodaterol (n = 34). Blood eosinophil count and high-sensitivity C-reactive protein (hs-CRP) were measured at baseline. Results: Lung function improved after 12 weeks (p < 0.05). Airway lumen area normalized to body surface area (Ai/BSA) increased from 10.2 ± 2.6 to 12.2 ± 2.7 mm²/m², whereas relative wall area (WA%) decreased from 58.3 (56.6–61.5) to 55.9 (54.4–57.9)% (both p < 0.001). Improvement in Ai/BSA did not differ between upper and lower lobes (p > 0.05). Higher baseline hs-CRP was associated with a smaller Ai/BSA increase (r = −0.454, p = 0.01). No statistically significant associations were detected between ΔAi/BSA and the evaluated baseline variables, including blood eosinophil count, Ai/BSA, age, smoking history and lung function measurements (all p > 0.05), or between blood eosinophil count and baseline Ai/BSA or WA% (both p > 0.05). Conclusions: Initial dual bronchodilator therapy improved lung function and CT-derived airway measurements. In this cohort, no statistically significant association was detected between blood eosinophil count and airway response, whereas higher hs-CRP was associated with a smaller Ai/BSA increase.
