A systematic review and meta-analysis on sodium tanshinone IIA sulfonate injection for the adjunctive therapy of pulmonary heart disease.

AIMS: Sodium tanshinone IIA sulfonate (STS) injection has been widely used as adjunctive therapy for pulmonary heart disease (PHD) in China. Nevertheless, the efficacy of STS injection has not been systematically evaluated so far. Hence, the efficacy of STS injection as adjunctive therapy for PHD was explored in this study. METHODS: Randomized controlled trials (RCTs) were screened from China Science and Technology Journal Database, China National Knowledge Infrastructure, Wanfang Database, PubMed, Sino-Med, Google Scholar, Medline, Chinese Biomedical Literature Database, Cochrane Library, Embase and Chinese Science Citation Database until 20 January 2024. Literature searching, data collection and quality assessment were independently performed by two investigators. The extracted data was analyzed with RevMan 5.4 and STATA 14.0. Basing on the methodological quality, dosage of STS injection, control group measures and intervention time, sensitivity analysis and subgroup analysis were performed. RESULTS: 19 RCTs with 1739 patients were included in this study. Results showed that as adjunctive therapy, STS injection combined with Western medicine showed better therapeutic efficacy than Western medicine alone for PHD by increasing the clinical effective rate (RR = 1.22; 95% CI, 1.17 to 1.27; p < 0.001), partial pressure of oxygen (MD = 10.16; 95% CI, 5.07 to 15.24; p < 0.001), left ventricular ejection fraction (MD = 8.66; 95% CI, 6.14 to 11.18; p < 0.001) and stroke volume (MD = 13.10; 95% CI, 11.83 to 14.38; p < 0.001), meanwhile decreasing the low shear blood viscosity (MD = -1.16; 95% CI, -1.57 to -0.74; p < 0.001), high shear blood viscosity (MD = -0.64; 95% CI, -0.86 to -0.42; p < 0.001), plasma viscosity (MD = -0.23; 95% CI, -0.30 to -0.17; p < 0.001), hematokrit (MD = -8.52; 95% CI, -11.06 to -5.98; p < 0.001), fibrinogen (MD = -0.62; 95% CI, -0.87 to -0.37; p < 0.001) and partial pressure of carbon dioxide (MD = -8.56; 95% CI, -12.09 to -5.02; p < 0.001). CONCLUSION: STS injection as adjunctive therapy seemed to be more effective than Western medicine alone for PHD. However, due to low quality of the included RCTs, more well-designed RCTs were necessary to verify the efficacy of STS injection.

Unraveling disparities: Probing gender, race, and geographic inequities in pulmonary heart disease mortality in the United States: An extensive longitudinal examination (1999-2020) leveraging CDC WONDER data.

This comprehensive study delves into the epidemiological landscape of Pulmonary Heart Disease (PHD) mortality in the United States from 1999 to 2020, leveraging the extensive CDC WONDER database. PHD encompasses conditions affecting the right side of the heart due to lung disorders or elevated pressure in the pulmonary arteries, including pulmonary hypertension, pulmonary embolism, and chronic thromboembolic pulmonary hypertension (CTEPH). Analyzing data from death certificates, demographic characteristics, and geographical segmentation, significant trends emerge. The age-adjusted mortality rates (AAMRs) for PHD-related deaths show a fluctuating pattern, initially decreasing from 1999 to 2006, followed by a steady increase until 2020. Male patients consistently exhibit higher AAMRs than females, with notable disparities observed among racial/ethnic groups and geographic regions. Non-hispanic (NH) Black or African American individuals, residents of specific states like Colorado and the District of Columbia, and those in the Midwest region demonstrate elevated AAMRs. Furthermore, nonmetropolitan areas consistently manifest higher AAMRs than metropolitan areas. These findings underscore the urgent need for intensified prevention and treatment strategies to address the rising mortality associated with PHD, particularly among vulnerable populations. Insights from this study offer valuable guidance for public health initiatives aimed at reducing PHD-related mortality and improving outcomes nationwide.

[Analysis of Risk Factors of Chronic Pulmonary Heart Disease in Patients With Pneumoconiosis]. / å°˜è‚ºç— æ‚£è€ å‘ç”Ÿæ ¢æ€§è‚ºå¿ƒç— çš„å±é™©å› ç´ åˆ†æž.

Objective: To explore the risk factors for developing chronic pulmonary heart disease in patients with pneumoconiosis. Methods: The medical records of pneumoconiosis patients admitted to an occupational disease hospital in Sichuan Province between January 2012 and November 2021 were collected. Kaplan-Meier (K-M) method, or product-limit method, was used to plot the incidence curves of pulmonary heart disease in the pneumoconiosis patients. Cox proportional hazard regression model was used to analyze the influencing factors associated with chronic pulmonary heart disease in patients with pneumoconiosis. Results: A total of 885 pneumoconiosis patients were included in this study. The follow-up time was 12 to 115 months and the median follow-up time was 43 months. A total of 138 patients developed chronic pulmonary heart disease and the incidence density of pulmonary heart disease was 38.50/1000 person-years. Multivariate Cox proportional hazard regression analysis showed that the influencing factors of pneumoconiosis inpatients developing chronic pulmonary heart disease included the following, being 50 and older (hazard ratio [HR]=1.85, 95% confidence interval [CI]: 1.25-2.74), stage Ⅲ pneumoconiosis (HR=2.43, 95% CI: 1.48-4.01), resting heart rate≥100 beats/min (HR=2.62, 95% CI: 1.63-4.21), the complication of chronic obstructive pulmonary disease (COPD) (HR=4.52, 95% CI: 2.12-9.63), underweight (HR=2.40, 95% CI: 1.48-3.87), overweight and obesity (HR=0.54, 95% CI: 0.34-0.86), and triacylglycerol (TG) (HR=0.69, 95% CI: 0.49-0.99). Conclusion: Old age, stage Ⅲ pneumoconiosis, high resting heart rate, low BMI, and the complication of COPD are risk factors for chronic pulmonary heart disease in pneumoconiosis patients, while overweight and obesity and TG are protective factors. Early identification of the risk factors and the adoption of the corresponding prevention measures are the key to preventing chronic pulmonary heart disease in patients with pneumoconiosis.

Platelet-to-Lymphocyte Ratio (PLR), Neutrophil-to-Lymphocyte Ratio (NLR), Monocyte-to-Lymphocyte Ratio (MLR), and Eosinophil-to-Lymphocyte Ratio (ELR) as Biomarkers in Patients with Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD).

Purpose: The study comprehensively evaluated the prognostic roles of the platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), basophil-to-lymphocyte ratio (BLR), and eosinophil-to-lymphocyte ratio (ELR) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Patients and Methods: Six hundred and nineteen patients with AECOPD and 300 healthy volunteers were retrospectively included into the study. The clinical characteristics of the patients with AECOPD and the complete blood counts (CBCs) of the healthy volunteers were collected. The associations of PLR, NLR, MLR, BLR, and ELR with airflow limitation, hospital length of stay (LOS), C-reactive protein (CRP), and in-hospital mortality in patients with AECOPD were analyzed. Results: Compared with the healthy volunteers, PLR, NLR, MLR, BLR, and ELR were all elevated in COPD patients under stable condition. PLR, NLR, MLR, and BLR were further elevated while ELR was lowered during exacerbation. In the patients with AECOPD, PLR, NLR, and MLR were positively correlated with hospital LOS as well as CRP. In contrast, ELR was negatively correlated with hospital LOS as well as CRP. Elevated PLR, NLR, and MLR were all associated with more severe airflow limitation in AECOPD. Elevated PLR, NLR, and MLR were all associated with increased in-hospital mortality while elevated ELR was associated with decreased in-hospital mortality. Binary logistic regression analysis showed that smoking history, FEV1% predicted, pneumonia, pulmonary heart disease (PHD), uric acid (UA), albumin, and MLR were significant independent predictors ofin-hospital mortality. These predictors along with ELR were used to construct a nomogram for predicting in-hospital mortality in AECOPD. The nomogram had a C-index of 0.850 (95% CI: 0.799-0.901), and the calibration curve, decision curve analysis (DCA), and clinical impact curve (CIC) further demonstrated its good predictive value and clinical applicability. Conclusion: In summary, PLR, NLR, MLR, and ELR served as useful biomarkers in patients with AECOPD.

Unraveling the role of the FHL family in cardiac diseases: Mechanisms, implications, and future directions.

Heart diseases are a major cause of morbidity and mortality worldwide. Understanding the molecular mechanisms underlying these diseases is essential for the development of effective diagnostic and therapeutic strategies. The FHL family consists of five members: FHL1, FHL2, FHL3, FHL4, and FHL5/Act. These members exhibit different expression patterns in various tissues including the heart. FHL family proteins are implicated in cardiac remodeling, regulation of metabolic enzymes, and cardiac biomechanical stress perception. A large number of studies have explored the link between FHL family proteins and cardiac disease, skeletal muscle disease, and ovarian metabolism, but a comprehensive and in-depth understanding of the specific molecular mechanisms targeting FHL on cardiac disease is lacking. The aim of this review is to explore the structure and function of FHL family members, to comprehensively elucidate the mechanisms by which they regulate the heart, and to explore in depth the changes in FHL family members observed in different cardiac disorders, as well as the effects of mutations in FHL proteins on heart health.

[Construction and validation of a risk prediction model for pneumoconiosis patients complicated with chronic pulmonary heart disease based on Tei index].

Objective: To conduct a statistical analysis on the condition of patients with pneumoconiosis complicated with chronic pulmonary heart disease based on the Tei index, and to establish a relevant prediction model. Methods: In March 2022, a retrospective analysis of 226 patients diagnosed with pneumoconiosis in the Department of Occupational Disease of Yantai Yantaishan Hospital from January 2016 to January 2022 was conducted. The patients with pneumoconiosis complicated by pulmonary heart disease were included in the pulmonary heart disease group and others were included in the non-pulmonary heart disease group. logistic regression analysis was used to screen out the relevant factors and establish a risk prediction model. Hosmer-Lemeshow test was applied to determine the goodness of fit of the model, and the receiver operating characteristic (ROC) area under the curve (AUC) was used to evaluate the predictive effect of the model. Results: Among the 226 patients with pneumoconiosis, 58 patients had chronic pulmonary heart disease, accounting for 25.7% of the surveyed population. The logistic analysis showed that the course of disease, pneumoconiosis stage and Tei index were influencing factors of pneumoconiosis complicated with pulmonary heart disease (P<0.05). A risk prediction model for pneumoconiosis patients complicated with pulmonary heart disease was developed: Z=6.253X(1)+1.265X(2)+1.423X(3)+9.264, in which X(1) was the stage of pneumoconiosis, X(2) was the course of disease, and X(3) was the Tei index. Hosmer-Lemeshow test was used to evaluate the goodness of fit of the risk prediction model for pneumoconiosis patients complicated with pulmonary heart disease, the results indicated that the prediction model was in good agreement with the actual situation (χ(2)=11.59, P=0.254). The diagnostic ability of the model was evaluated by the ROC curve, and the results showed that its AUC was 0.897, the sensitivity was 0.947, and the specificity was 0.784. Conclusion: The course of disease, pneumoconiosis stage and Tei index are the influencing factors of pneumoconiosis complicated with pulmonary heart disease. The model constructed based on these factors has a good prediction effect, which can provide a basis for the early detection and intervention of pneumoconiosis complicated with pulmonary heart disease.

Diagnostic, prognostic and clinical value of left ventricular radial strain to identify paradoxical septal motion in ventilated patients with the acute respiratory distress syndrome: an observational prospective multicenter study.

BACKGROUND: Acute cor pulmonale (ACP) is prognostic in patients with acute respiratory distress syndrome (ARDS). Identification of paradoxical septal motion (PSM) using two-dimensional echocardiography is highly subjective. We sought to describe feature-engineered metrics derived from LV radial strain changes related to PSM in ARDS patients with ACP of various severity and to illustrate potential diagnostic and prognostic yield. METHODS: This prospective bicentric study included patients under protective ventilation for ARDS related to COVID-19 who were assessed using transesophageal echocardiography (TEE). Transgastric short-axis view at mid-papillary level was used to visually grade septal motion, using two-dimensional imaging, solely and combined with LV radial strain: normal (grade 0), transient end-systolic septal flattening (grade 1), prolonged end-systolic septal flattening or reversed septal curvature (grade 2). Inter-observer variability was calculated. Feature engineering was performed to calculate the time-to-peak and area under the strain curve in 6 LV segments. In the subset of patients with serial TEE examinations, a multivariate Cox model analysis accounting for new-onset of PSM as a time-dependent variable was used to identify parameters associated with ICU mortality. RESULTS: Overall, 310 TEE examinations performed in 182 patients were analyzed (age: 67 [60-72] years; men: 66%; SAPSII: 35 [29-40]). Two-dimensional assessment identified a grade 1 and grade 2 PSM in 100 (32%) and 48 (15%) examinations, respectively. Inter-rater reliability was weak using two-dimensional imaging alone (kappa = 0.49; 95% CI 0.40-0.58; p < 0.001) and increased with associated LV radial strain (kappa = 0.84, 95% CI 0.79-0.90, p < 0.001). The time-to-peak of mid-septal and mid-lateral segments occurred significantly later in systole and increased with the grade of PSM. Similarly, the area under the strain curve of these segments increased significantly with the grade of PSM, compared with mid-anterior or mid-inferior segments. Severe acute cor pulmonale with a grade 2 PSM was significantly associated with mortality. Requalification in an upper PSM grade using LV radial strain allowed to better identify patients at risk of death (HR: 6.27 [95% CI 2.28-17.2] vs. 2.80 [95% CI 1.11-7.09]). CONCLUSIONS: In objectively depicting PSM and quantitatively assessing its severity, TEE LV radial strain appears as a valuable adjunct to conventional two-dimensional imaging.

Pulmonary Heart Disease Associated Mortality - China, 2014-2021.

Introduction: Over the latter half of the previous century, pulmonary heart disease (PHD) emerged as a significant public health issue in China. However, the current mortality rate is unknown. Utilizing the Multiple Cause of Death database, the present study aims to investigate the current state and progression of PHD-associated death in China. Methods: Data from the China National Mortality Surveillance System were used to analyze progression in mortality rates attributable to PHD from 2014 to 2021. To standardize population structure for each year during the investigation period, demographic information from the 2020 census was employed as the reference population. Age-standardized mortality rates (ASMR) were determined based on sex, urban-rural area, and region. To identify trends in ASMR, a joinpoint regression analysis was executed. Results: The ASMR of PHD exhibited a marked decrease, falling from 61.68 per 100,000 in 2014 to 28.53 per 100,000 in 2021. This downward trend was observable in both genders, all regions, and both urban and rural settings. The greatest ASMR values were documented in the western region. Comparative observations revealed a higher ASMR in rural areas versus urban ones and in males versus females. PHD-associated deaths predominantly occurred among older individuals, particularly those aged 80 and above. Chronic obstructive pulmonary disease (COPD) emerged as the principal underlying cause of death PHD-associated mortalities, accounting for between 87.41% and 93.42% of cases throughout the period 2014-2021. Conclusions: There was a declining trend in PHD mortality in China from 2014 to 2021, with COPD accounting for a significant proportion of these deaths. Given the high prevalence of COPD and the escalating population aging in China, PHD remains a significant health concern that warrants further attention.

Hemodynamic characteristics in patients with pulmonary hypertension and chronic obstructive pulmonary disease: A retrospective monocentric cohort study.

BACKGROUND: Pulmonary hypertension (PH) is a hemodynamic condition characterized by an abnormal elevation in pulmonary arterial pressures. Several pathophysiological pre-capillary and post-capillary mechanisms have been described. PH is a common complication of chronic obstructive pulmonary disease (COPD), however, the prevalence of each mechanism in the development of PH in patients with COPD has been hardly studied. METHODS: We reported the clinical, functional, hemodynamic characteristics and outcomes of patients diagnosed with COPD and PH among the expert PH center of Nancy between January 1st, 2015 and March 31st, 2021. RESULTS: 123 patients with COPD and PH were included. Most patients (n=122, 99%) had a pre-capillary mechanism, 9% (n=11) a post-capillary mechanism, and 1% (n=1) an unclassified mechanism. 111 (90%) patients had pure pre-capillary PH and 11 (9%) patients had combined pre- and post-capillary PH. Combined pre- and post-capillary PH group was characterized by higher prevalence of cardiovascular comorbidities and of sleep apnea-hypopnea syndrome, a higher body mass index, lower lung volumes, higher mean pulmonary arterial pressure, pulmonary arterial wedge pressure and right atrial pressure. At follow-up (median 30 months), 52 patients had died, and 11 had undergone lung transplantation. One-year, three-year and five-year transplant-free survival rates were 71%, 29% and 11% respectively. There was no difference on outcomes between groups. CONCLUSION: PH in COPD patients is mostly due to pre-capillary mechanism. However, the existence of various and numerous comorbidities in COPD, especially cardiovascular, can lead to the participation of post-capillary mechanisms in the development of PH. Further studies are needed to confirm these findings and to assess the impact on outcomes and management strategies in these different patients.

[Analysis of serum CA125 and related influencing factors in silicosis patients with pulmonary heart disease].

Objective: To analyze the serum carbohydrate antigen 125 (CA125) level and its influencing factors in male silicosis patients with pulmonary heart disease. Methods: In October 2021, data of 38 male patients with simple silicosis (silicosis group), 28 cases of silicosis with pulmonary heart disease (pulmonary heart disease group), and 27 healthy controls (control group) in the same age group were collected in inpatient and outpatient of Nanjing Occupational Disease Prevention and Control Hospital from January 2017 to December 2020. The serum CA125 levels of the three groups were compared, and the correlation between disease-related indexes and serum CA125 in silicosis patients with pulmonary heart disease was analyzed, as well as the influencing factors of pulmonary heart disease and serum CA125 levels in silicosis patients. Results: The serum CA125 level[ (19.95±7.52) IU/ml] in pulmonary heart disease group was higher than that in silicosis group[ (12.98±6.35) IU/ml] and control group[ (9.17±5.32) IU/ml] (P<0.05). There was no significant difference in serum CA125 level between the silicosis group and the control group (P>0.05). Serum CA125 levels were positively correlated with blood uric acid and fasting blood glucose in silicosis patients with pulmonary heart disease (r=0.39, 0.46, P<0.05). Serum CA125 level was a risk factor for silicosis patients with pulmonary heart disease (OR=1.13, 95%CI: 1.02-1.24, P<0.05). Dust exposure time, lactate dehydrogenase and smoking history were positively correlated with serum CA125 level in silicosis patients (P<0.05) . Conclusion: The serum CA125 level of male silicosis patients with pulmonary heart disease is significantly increased, and the level of CA125 is correlated with the level of fasting blood glucose and blood uric acid.

A 7-year-old boy with recurrent cyanosis and tachypnea: A case report.

BACKGROUND: Brain tumors are the most common solid tumors in children and comprise 25% of all malignancies in children. Common presentations include headache, nausea and vomiting, gait abnormality, papilledema, and epileptic seizure; however, some symptoms can be very insidious, with atypical and misleading manifestations. CASE SUMMARY: Here, we report a 7-year-old boy who presented with recurrent cyanosis and tachypnea after exercise for 2 years. His body mass index was 26.43 kg/m2. Hepatosplenomegaly, blood gas analysis, biochemical parameters, chest computed tomography scan, and echocardiograph suggested type II respiratory failure, pulmonary heart disease, and mild liver injury. Non-invasive breathing support, antibiotics, and anti-heart failure therapy were given. The patient's pulse oxygen saturation increased to over 95% when he was awake but dropped to 50%-60%, accompanied by cyanosis, during sleep while receiving high-flow nasal cannula oxygen. Sleep-related breathing disorder was suspected. In the intensive care unit, however, polysomnography was unavailable. Brain magnetic resonance imaging revealed a space-occupying (cerebellum and brainstem) lesion, which was later confirmed to be pleomorphic xanthoastrocytoma by surgery and histopathology by tissue biopsy. CONCLUSION: When treating patients with cyanosis and tachypnea, a broad differential diagnosis should be considered, including brain tumor.

When you hear hoofbeats, think zebras - pulmonary veno-occlusive disease: A case report.

Pulmonary veno-occlusive disease (PVOD) is a rare disease. It may be idiopathic or associated, in particular, with connective tissue disease, or it may develop after radiation exposure; in heritable forms of PVOD, the inheritance is autosomal recessive due to the presence of homozygous or compound heterozygous pathogenic variants in the EIF2AK4 gene. We describe the case of a young man whose PVOD was initially misdiagnosed as chronic thromboembolic pulmonary hypertension despite worsening after riociguat, nonspecific computed tomography pulmonary angiogram findings, and parental consanguinity could suggest an autosomal recessive disease. The correct diagnosis and the correct treatment are crucial given the high mortality rate of this disease.

Ingenuity pathway analysis of the human cardiac cell Atlas identifies differences between right and left ventricular cardiomyocytes.

Pharmaceuticals for left ventricular (LV) dysfunction do not have similar success in right ventricular (RV) failure, which may reflect biological differences between the ventricles. In this study, we performed Ingenuity Pathway Analysis of the Human Cell Atlas to understand how the transcriptomic signatures of the RV and LV differ.

O uso do core set da CIF para avaliação de pacientes com distúrbios cardiorrespiratórios / The use of the ICF core set for the evaluation of patients with cardiorespiratory disorders

Introdução: A Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF) categoriza a saúde e deficiência do indivíduo considerando a funcionalidade e os fatores contextuais. No entanto, a CIF apresenta muitas categorias que dificultam o seu uso diário e, por isso, foram criados os core sets. Entre os diversos core sets propostos, existe um core set para condições cardiorrespiratórias pós-agudas. Objetivo: classificar os pacientes com alterações cardíacas, respiratórias e mistas, assistidos ambulatoriais por meio de um core sets para esta população, além de verificar se existem diferenças entre os grupos na aplicação deste core set. Métodos: Foram avaliados indivíduos com diagnóstico clínico de doenças cardiorrespiratórias em acompanhamento fisioterapêutico ambulatorial para reabilitação cardiopulmonar. A amostra foi dividida em três grupos: cardíacos, respiratórios e mistos. Os pacientes foram avaliados por meio da versão abreviada do core set para condições cardiorrespiratórios pós-agudas, funcionalidade, força de preensão palmar e dos músculos respiratórios. Resultados: A amostra foi composta por 67 indivíduos alocados de acordo com seu comprometimento. Verificou-se que apenas as funções de energia e impulso, cardíaca e de ingestão, estrutura do sistema respiratório e a atividade andar apresentaram respostas significativamente diferentes entres os grupos. Pacientes com distúrbios respiratórios, cardíacos e mistos apresentam perfis funcionais semelhantes, porém as categorias com diferença desse perfil foram as relacionadas ao sistema respiratório, atividades e funções relacionadas ao aumento da demanda metabólica como andar. Conclusão: Assim é possível afirmar que o core set auxilia a identificar as disfunções dos pacientes sem depender se sua disfunção é cardíaca, respiratória ou mista que pode ser uma ferramenta utilizada no meio clínico.

Introduction: The International Classification of Functioning, Disability and Health (ICF) categorizes an individual's health and disability considering functionality and contextual factors. However, the ICF has many categories that make it difficult to use daily, and that's why core sets were created. Among the various proposed core sets, there is a core set for post-acute cardiorespiratory conditions. Objective: to classify patients with cardiac, respiratory and mixed alterations assisted in outpatient clinics using a core set for this population, in addition to verifying whether there are differences between the groups in the application of this core set. Methods: Individuals with a clinical diagnosis of cardiorespiratory in outpatient physical therapy follow-up for cardiopulmonary rehabilitation diseases were evaluated. The sample was divided into three groups: cardiac, respiratory and mixed. Patients were evaluated using the abbreviated version of the core set for post-acute cardiorespiratory conditions, functionality, handgrip strength and respiratory muscles. Results: The sample consisted of 67 individuals allocated according to their commitment. It was found that only the energy and impulse, cardiac and ingestion functions, structure of the respiratory system and walking activity showed significantly different responses between the groups. Patients with respiratory, cardiac and mixed disorders have similar functional profiles, but the categories with difference in this profile were those related to the respiratory system, activities and functions related to increased metabolic demand such as walking. Conclusion: Thus, it is possible to affirm that the core set helps to identify the patients' dysfunctions without depending on whether their dysfunction is cardiac, respiratory or mixed, which can be a tool used in the clinical environment.

Association of right ventricle diastolic diameter with pulmonary function, exercise tolerance and exacerbation period in patients with chronic obstructive pulmonary disease: A prospective study.

BACKGROUND: The echocardiogram is a useful method for monitoring the cardiovascular complications of chronic obstructive pulmonary disease (COPD), but it is not clear if morphological and functional cardiac variables are able to identify patients with unfavorable COPD progression. OBJECTIVE: The aim of this study was to investigate morphological and functional echocardiographic variables associated with exacerbation of the disease, pulmonary function parameters and functional capacity evaluation in COPD patients. METHOD: A longitudinal observational study including 91 patients diagnosed with COPD, who were stratified in two groups according to their basal right ventricle diastolic diameter (RVDD) measuring greater and less than 35 mm. They underwent clinical evaluation, echocardiography, spirometry and 6-minute walking-test (6MWT). RESULTS: The study found that patients with RVDD greater than 35 mm showed worse functional capacity in the 6MWT (p = 0.05) and more exacerbation of the disease during the one-year follow-up (p = 0.05). There were correlations of greater RVDD vs forced vital capacity (R = -0.27; p = 0.02) and distance in the 6MWT (R = 0.55; p = 0.03) in patients with exacerbation. In the univariate regression analysis, the RVDD was responsible for 55% of the variation in distance in the 6MWT (-0.75 m) in COPD patients. CONCLUSION: The RV dilation is associated with unfavorable prognostic markers in COPD, such as the worsening of the functional capacity and more frequent exacerbations. The echocardiogram may be a useful tool to identify patients who need more aggressive strategies to control the evolution of the disease with potential impact in pulmonary rehabilitation.
