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.

Risk factors for mortality in patients with acute exacerbation of cor pulmonale in plateau.

BACKGROUND: The risk factors for mortality might differ between patients with acute exacerbation of chronic pulmonary heart disease in plains and plateaus, while there is a lack of evidence. METHOD: Patients diagnosed with cor pulmonale at Qinghai Provincial People's Hospital were retrospectively included between January 2012 and December 2021. The symptoms, physical and laboratory examination findings, and treatments were collected. Based on the survival within 50 days, we divided the patients into survival and death groups. RESULTS: After 1:10 matching according to gender, age, and altitude, 673 patients were included in the study, 69 of whom died. The multivariable Cox proportional hazards analysis showed that NYHA class IV (HR = 2.03, 95%CI: 1.21-3.40, P = 0.007), type II respiratory failure (HR = 3.57, 95%CI: 1.60-7.99, P = 0.002), acid-base imbalance (HR = 1.82, 95%CI: 1.06-3.14, P = 0.031), C-reactive protein (HR = 1.04, 95%CI: 1.01-1.08, P = 0.026), and D-dimer (HR = 1.07, 95%CI: 1.01-1.13, P = 0.014) were risk factors for death in patients with cor pulmonale at high altitude. Among patients living below 2500 m, cardiac injury was a risk factor for death (HR = 2.47, 95%CI: 1.28-4.77, P = 0.007), while no significant association was observed at ≥ 2500 m (P = 0.057). On the contrary, the increase of D-dimer was only a risk factor for the death of patients living 2500 m and above (HR = 1.23, 95% CI: 1.07-1.40, P = 0.003). CONCLUSION: NYHA class IV, type II respiratory failure, acid-base imbalance, and C- reactive protein may increase the risk of death in patients with cor pulmonale. Altitude modified the association between cardiac injury, D-dimer, and death in patients with cor pulmonale.

Etiology, characteristics and occurrence of heart diseases in rural Lesotho (ECHO-Lesotho): A retrospective echocardiography cohort study.

BACKGROUND: In 2019, 600'000 people in Africa died of heart failure and heart diseases will increase on the continent. It is crucial to understand the regional etiologies and risk factors for heart failure and underlying heart diseases. However, echocardiography data from rural Africa are scarce and from Lesotho non-existent. This study aims to examine the occurrence, characteristics and etiology of heart failure and heart diseases using echocardiography data from a referral hospital in rural Lesotho. METHODS: We conducted a retrospective cohort study at Seboche Mission Hospital, the only referral hospital in Butha-Buthe district (Lesotho) with an echocardiography department. We included data from all individuals referred to the department between January 2020 and May 2021. From non-hospitalized patients echocardiographic diagnosis, sex and age were available, from hospitalized patients additional sociodemographic and clinical data could be extracted. RESULTS: In the study period, a total of 352 echocardiograms were conducted; 213 had abnormal findings (among them 3 children). The majority of adult participants (130/210; 64%) were female and most frequent heart diseases were hypertensive (62/210, 30%), valvular (39/210, 19%) and chronic pulmonary (37/210, 18%). Heart failure represented 11% of hospitalizations in the same period. Among the 126 hospitalized heart failure patients, the most common etiology was chronic pulmonary heart disease (32/126; 25%). Former mine workers and people with a history of tuberculosis were more likely to have a chronic pulmonary heart disease. CONCLUSIONS: The leading cause of heart disease in this setting is hypertension. However, in contrast to other African epidemiological studies, chronic pulmonary heart disease is unexpectedly common. There is an urgent need to improve awareness and knowledge about lung diseases, make diagnostic and therapeutic options available and increase prevention.

Cardiovascular disease in women with breast cancer - a nationwide cohort study.

BACKGROUND: There is increasing concern about cardiovascular disease (CVD) after breast cancer (BC). The aim of this study was to estimate the prevalence of different types of CVD in women diagnosed with BC compared to cancer-free controls as well as the incidence of CVD after BC diagnosis. METHODS: We performed a cohort study based on data from national registries covering the entire Danish population. We followed 16,505 cancer-naïve BC patients diagnosed from 2003 to 2007 5 years before and up to 10 years after BC diagnosis compared to 165,042 cancer-free controls. RESULTS: We found that 15.6% of BC patients were registered with at least one CVD diagnosis in hospital records before BC diagnosis. Overall, BC patients and controls were similar with regard to CVD comorbidity before BC diagnosis. After BC diagnosis, the incidence of all CVD diagnoses combined was significantly higher in BC patients than controls up to approximately 6 years after the index date (BC diagnosis). After 10 years, 28% of both BC patients and controls (without any CVD diagnosis up to 5 years before the index date) had at least one CVD diagnosis according to hospital records. However, the incidence of heart failure, thrombophlebitis/thrombosis and pulmonary heart disease including pulmonary embolism remained higher in BC patients than controls during the entire 10-year follow-up period. After 10 years, 2.7% of BC patients compared to 2.5% of controls were diagnosed with heart failure, 2.7% of BC patients compared to 1.5% of controls were diagnosed with thrombophlebitis/thrombosis, and 1.5% of BC patients compared to 1.0% of controls were diagnosed with pulmonary heart disease according to hospital records. Furthermore, we found that the risk of heart failure and thrombophlebitis/thrombosis was higher after chemotherapy. CONCLUSIONS: Focus on CVD in BC patients is important to ensure optimum treatment with regard to BC as well as possible CVD. Strategies to minimise and manage the increased risk of heart failure, thrombophlebitis/thrombosis and pulmonary heart disease including pulmonary embolism in BC patients are especially important.

Associations of toothbrushing behaviour with risks of vascular and nonvascular diseases in Chinese adults.

Accumulating evidence has shown that poor oral hygiene is associated with increased risk of cardiometabolic diseases in Western populations. However, its relevance about the relationships in Chinese adults remains unclear. The China Kadoorie Biobank enrolled 512 715 adults aged 30-79 years in China during 2004-2008. Cox regression was used to estimate adjusted hazard ratios (HRs) for each disease associated with measures of oral hygiene. Overall 9.3% of the participants reported rarely or never brushing teeth at baseline. Participants who rarely or never brushed teeth had adjusted HR of 1.12 (95% CI: 1.09, 1.15) for MVE, with similar HRs for stroke (1.08, 1.05-1.12), intracerebral haemorrhage (1.18, 1.11-1.26) and pulmonary heart disease (1.22, 1.13-1.32) compared with those who brushed teeth regularly. Those who did not brush teeth also had increased risk of cancer (1.09, 1.04-1.14), chronic obstructive pulmonary disease (COPD) (1.12, 1.05-1.20), liver cirrhosis (1.25, 1.09-1.44) and all-cause death (1.25, 1.21-1.28) but not type 2 diabetes (0.94, 0.86-1.03) and chronic kidney disease (0.98, 0.81-1.18). Among Chinese adults, we found that poor oral hygiene is associated with higher risks of major vascular disease, cancer, COPD, liver cirrhosis and all-cause deaths, but not type 2 diabetes and chronic kidney disease.

Clinico-epidemiological characteristics of men and women with a new diagnosis of chronic obstructive pulmonary disease: a database (SIDIAP) study.

BACKGROUND: The risk of developing Chronic Obstructive Pulmonary Disease (COPD), the associated comorbidities and response to bronchodilators might differ in men and women. The objective of this study was to determine the prevalence of COPD and the clinic-epidemiological characteristics of primary care patients with COPD according to gender. METHODS: This is a cross-sectional study using electronic healthcare records Catalonia (Spain), during the 01/01/2012-31/12/2017 period. Patients from the SIDIAP database (System for the Development of Research in Primary Care) were included (5,800,000 patients registered in 279 primary care health centres). Clinic-demographic characteristics, comorbidities and blood tests results were collected for each patient. Adjusted OR (ORa) with logistic regression methods were used to determine variables associated with men and women. RESULTS: From an initial sample of 800,899 people, 24,135 (3%) were considered COPD patients, and 22.9%were women. The most common risk factors in women were bronchiectasis (ORa = 20.5, SD = 19.5-21.6), age > 71 years (ORa = 18.8; SD = 17.3-20.5), cor pulmonale (ORa = 5.2; SD = 4.3-6.7) and lung cancer (ORa = 3.6, SD = 3.2-4.0). Men and women presented the same comorbidities, though the strength of association was different for each gender. CONCLUSIONS: Patients suffering high comorbidity rates. Comorbidities are similar in men and women, although the strength of association varies according to gender. Women are more susceptible to the harmful effects of smoking and present a higher proportion of bronchiectasis and OSAS.

Trend of in-hospital deaths by pulmonary embolism in Ecuador. Findings from 2011-2018 national reports.

BACKGROUND: Pulmonary embolism (PE) is a potentially fatal disease related to venous thromboembolism. Information regarding this pathology in the Ecuadorian population is limited. This study aims to present the PE hospital mortality rates (HMR) in Ecuador, analyze its trend and risk factors. METHODS: An epidemiological, descriptive and cross-sectional study based on the reporting and trend analysis of pulmonary embolism HMR in the Ecuadorian population from 2011 to 2018 through the governmental database of the Ecuadorian National Statistics and Census Institute, was conducted. RESULTS: In Ecuador, PE hospital discharges (HD) varied from 358 in 2011 to 424 in 2018. More than 60% of patients were older than 60 years. Also, the frequency of PE with acute cor pulmonale increased from 3.07% in 2011 to 16.98% in 2018 (P<0.05). The HMR by 100 HD increased between 2011 (12.85/100 HD) and 2018 (17.02/100 HD) (P<0.05), with the highest rate reported in 2017 (21.52/100 HD). In the period studied, 505 in-hospital deaths were reported in patients with PE, the average age in this group was 64.3 years, 58.42% were female, and 10.89% had acute cor pulmonale (ICD-10 I26.0). Risk factors associated with PE in-hospital death were acute cor pulmonale (OR 1.63, 95% CI: 1.18 to 2.25, P<0.01) and 60 years or more (OR 1.73, 95% CI 1.40-2.15, P<0.01). CONCLUSION: A significant increase in PE HMR in Ecuador was found. Also, acute cor pulmonale and age of 60 years or more may be potential risk factors for in-hospital death in patients with PE.

Participation weighting based on sociodemographic register data improved external validity in a population-based cohort study.

OBJECTIVE: To investigate whether inverse probability of participation weighting (IPPW) using register data on sociodemographic and disease history variables can improve external validity in a cohort study with selective participation. STUDY DESIGN AND SETTING: We fitted various IPPW models by logistic regression using register data for the participants (n = 1,111) and nonparticipants (n = 1,132) of a Swedish cohort study. For each of six diagnostic groups, we then estimated (1) weighted disease prevalence proportions and (2) weighted cross-sectional associations (odds ratios) between sociodemographic variables and disease prevalence. Using register data on the remaining individuals of the entire study population of men and women aged 50-64 years (n = 22,259), we addressed how the choice of variables used for IPPW influenced estimation errors. RESULTS: Disease prevalence proportions were generally underestimated in the absence of IPPW but became markedly closer to population values after IPPW using sociodemographic variables. We found limited evidence of selective participation bias in association estimates, but IPPW improved external validity when bias was present. CONCLUSIONS: IPPW using sociodemographic register data can improve the external validity of disease prevalence estimates in cohort studies with selective participation. The performance of IPPW for association estimates merits further investigations in longitudinal settings and larger cohorts.

Cigarette and e-cigarette dual use and risk of cardiopulmonary symptoms in the Health eHeart Study.

E-cigarettes are promoted as healthier alternatives to conventional cigarettes. Many cigarette smokers use both products. It is unknown whether the additional use of e-cigarettes among cigarette smokers (dual users) is associated with reduced exposure to tobacco-related health risks. Cross-sectional analysis was performed using baseline data from the Health eHeart Study, among English-speaking adults, mostly from the United States. Cigarette use (# cigarettes/day) and/or e-cigarette use (# days, # cartridges, and # puffs) were compared between cigarette only users vs. dual users. Additionally, we examined cardiopulmonary symptoms/ conditions across product use: no product (neither), e-cigarettes only, cigarettes only, and dual use. Among 39,747 participants, 573 (1.4%) reported e-cigarette only use, 1,693 (4.3%) reported cigarette only use, and 514 (1.3%) dual use. Dual users, compared to cigarette only users, reported a greater median (IQR) number of cigarettes per day, 10.0 (4.0-20.0) vs. 9.0 (3.0-15.0) (p < .0001), a lower (worse) median (IQR) SF-12 general health score, 3.3 (2.8-3.8) vs. 3.5 (2.8-3.9) (p = .0014), and a higher (worse) median (IQR) breathing difficulty score in the past month, 2.0 (1.0-2.0) vs. 1.0 (1.0-2.0) (p = .001). Of the 19 cardiopulmonary symptoms/ conditions, having a history of arrhythmia was significantly different between cigarette only users (14.2%) and dual users (17.8%) (p = .02). In this sample, dual use was not associated with reduced exposure to either (i) cigarettes, compared to cigarette only users or (ii) e-cigarettes, compared to e-cigarette only users. E-cigarette only use, compared to no product use, was associated with lower general health scores, higher breathing difficulty scores (typically and past month), and greater proportions of those who responded 'yes' to having chest pain, palpitations, coronary heart disease, arrhythmia, COPD, and asthma. These data suggest the added use of e-cigarettes alone may have contributed to cardiopulmonary health risks particularly respiratory health risks.

A predominance of hypertensive heart disease among patients with cardiac disease in Buea, a semi-urban setting, South West Region of Cameroon.

OBJECTIVE: The pattern of heart disease is diverse within and among world regions. The little data on the spectrum of heart disease in Cameroon has been so far limited to major cities. We sought to describe the pattern of heart disease in Buea, the South West Region of Cameroon, a semi-urban setting. This was a descriptive cross-sectional study. Between June 2016 and April 2017 the echocardiography register of the Buea Regional Hospital was surveyed. We extracted data on the age, sex and echocardiographic diagnosis. RESULTS: Out of 529 patients who underwent echocardiography, 239 (45.2%) had a definite heart disease. There were 137 (57.3%) females. The mean age was 58 years (range 3-94 years). The most common echocardiographic diagnoses were hypertensive heart disease (43.2%), dilated cardiomyopathies (17.6%), ischemic heart diseases (9.6%), and cor pulmonale (8.8%). Rheumatic heart disease affected 6.7% of the patients. The most common rheumatic heart disease was mitral stenosis followed by mitral regurgitation. Congenital heart disease represented 2.1% and 5 patients (2.1%) had pulmonary hypertension. Hypertensive heart disease is the most common cardiac disease in this semi-urban region in Cameroon. Rheumatic heart disease still affects a sizable proportion of patients. Prevention of cardiac disease in our setting should focus on mass screening, the treatment and control of hypertension.

A ten-year review of chronic cor pulmonale secondary to respiratory diseases in Ghana.

Chronic cor pulmonale is defined as right ventricular failure secondary to pulmonary hypertension. Our study reviewed all cases of chronic cor pulmonale secondary to respiratory diseases in a ten-year period (2004-20014) in the Department of Child Health, Korle-Bu Teaching Hospital, Ghana. Nine cases of chronic cor pulmonale were recorded during the period. The age range was 1-9 years (average age = 3 years). Obstructive sleep apnoea secondary to adenoid hypertrophy was the commonest cause of pulmonary hypertension.

Impact of neoadjuvant chemotherapy and chemoradiotherapy on postoperative cardiopulmonary complications in patients with esophageal cancer.

The effectiveness of neoadjuvant chemotherapy (nCT) or chemoradiotherapy (nCRT) for esophageal cancer patients is well established. However, neoadjuvant therapy may induce severe adverse effects that could increase postoperative morbidity. The current study evaluated the impacts of nCT and nCRT on postoperative cardiopulmonary complications in patient with esophageal cancer. We conducted a prospective study in esophageal cancer patients who received nCT (n = 126) or nCRT (n = 141) prior to surgery. Surgery was performed in all these patients following nCT or nCRT treatment. More patients occurred pneumonia in the nCRT-treated group compared with the nCT group (P < 0.01). The E-velocity (early diastolic filling velocity) decreased significantly (P = 0.026), while the N-terminal pro-brain natriuretic peptide (NT-proBNP) significantly increased (P < 0.01) in patients of the nCRT group compared with patients from the nCT group. Furthermore, a multivariate analysis revealed that nCRT was correlated with the incidence of pneumonia and NT-proBNP level significantly. The nCRT caused more cardiopulmonary toxicity than nCT. The strategies are needed to prevent the postoperative cardiopulmonary complications especially in patients with nCRT treatment.

Prognostic Importance of Dyspnea for Cardiovascular Outcomes and Mortality in Persons without Prevalent Cardiopulmonary Disease: The Atherosclerosis Risk in Communities Study.

BACKGROUND: The relationship between dyspnea and incident heart failure (HF) and myocardial infarction (MI) among patients without previously diagnosed cardiopulmonary disease is unclear. We studied the prognostic relevance of self-reported dyspnea for cardiovascular outcomes and all-cause mortality in persons without previously diagnosed cardiopulmonary disease. METHODS AND RESULTS: We studied 10 881 community-dwelling participants (mean age 57±6, 56% women, 25% black) who were free of prevalent cardiopulmonary disease from Atherosclerosis Risk in Communities Study. Dyspnea status at study entry using the modified Medical Research Council (mMRC) scale. The primary outcomes were time to HF, MI or all-cause death. Dyspnea prevalence was 22%, and was mild (mMRC grade 1 or 2) in 21% and moderate-to-severe (mMRC 3 or 4) in 1%. The main correlates of dyspnea were older age, female sex, higher BMI and active smoking. Over a follow-up of 19±5 years, greater self-reported dyspnea severity was associated with worse prognosis. Mild dyspnea was associated with significantly heightened risk of HF (adjusted Hazard Ratio, HR,1.30; 95% CI: 1.16-1.46), MI (adjusted HR 1.34; 95%CI: 1.20-1.50), and death (adjusted HR 1.16; 95%CI: 1.06-1.26), with moderate/severe dyspnea associated with an even greater risk (adjusted HR 2.14, 95%CI: 1.59-2.89; 1.93, 95%CI: 1.41-2.56; 1.96, 95%CI: 1.55-2.48, respectively). CONCLUSION: In community-dwelling persons free of previously diagnosed cardiopulmonary disease, self-reported dyspnea is common and, even when of mild intensity, it is independently associated with a greater risk of incident HF, MI, and death. Our data emphasize the prognostic importance of even mild self-reported dyspnea for cardiovascular outcomes.

Predictors of costs from the hospital perspective of primary pulmonary embolism.

The objective of this study was to estimate the total hospital cost per patient admitted through the emergency department with a primary diagnosis of pulmonary embolism (PE), and to identify the main components and predictors of costs.Actual costs of care of 652 consecutive patients hospitalised in 10 general hospitals in Belgium, including 31 outlier patients in terms of length of stay (4.8%), were obtained by aggregating all cost components contributing to care of each patient.In both inlier and outlier patients, the mean total cost per patient increased linearly with the degree of severity of illness classes related to the All Patient Refined Diagnosis Related Group (p<0.0001). Medical procedures, nursing activities and hospitalisation accommodation were the main cost components. We identified six independent predictors of costs in inliers: age group, chronic pulmonary heart disease, heart failure, admission to intensive care unit, initial thrombolysis treatment and type of hospital. There was a statistically significant linear trend between age groups and costs (p<0.0001).An increasing burden of comorbid illness was strongly associated with increasing actual cost for caring hospitalised patients for PE. Increasing age was associated with an increase in all main cost components.

Acute cor pulmonale during protective ventilation for acute respiratory distress syndrome: prevalence, predictors, and clinical impact.

RATIONALE: Increased right ventricle (RV) afterload during acute respiratory distress syndrome (ARDS) may induce acute cor pulmonale (ACP). OBJECTIVES: To determine the prevalence and prognosis of ACP and build a clinical risk score for the early detection of ACP. METHODS: This was a prospective study in which 752 patients with moderate-to-severe ARDS receiving protective ventilation were assessed using transesophageal echocardiography in 11 intensive care units. The study cohort was randomly split in a derivation (n = 502) and a validation (n = 250) cohort. MEASUREMENTS AND MAIN RESULTS: ACP was defined as septal dyskinesia with a dilated RV [end-diastolic RV/left ventricle (LV) area ratio >0.6 (≥1 for severe dilatation)]. ACP was found in 164 of the 752 patients (prevalence of 22 %; 95 % confidence interval 19-25 %). In the derivation cohort, the ACP risk score included four variables [pneumonia as a cause of ARDS, driving pressure ≥18 cm H2O, arterial oxygen partial pressure to fractional inspired oxygen (PaO2/FiO2) ratio <150 mmHg, and arterial carbon dioxide partial pressure ≥48 mmHg]. The ACP risk score had a reasonable discrimination and a good calibration. Hospital mortality did not differ between patients with or without ACP, but it was significantly higher in patients with severe ACP than in the other patients [31/54 (57 %) vs. 291/698 (42 %); p = 0.03]. Independent risk factors for hospital mortality included severe ACP along with male gender, age, SAPS II, shock, PaO2/FiO2 ratio, respiratory rate, and driving pressure, while prone position was protective. CONCLUSIONS: We report a 22 % prevalence of ACP and a poor outcome of severe ACP. We propose a simple clinical risk score for early identification of ACP that could trigger specific therapeutic strategies to reduce RV afterload.
