Pericardial Diseases Mortality Trends in Brazil From 2000 to 2022

Background Pericardial diseases manifest in various clinical forms, including acute pericarditis, constrictive pericarditis, pericardial effusion, and cardiac tamponade, with acute pericarditis being the most prevalent. These conditions significantly contribute to mortality rates. Therefore, this article aimed to analyze mortality trends in the Brazilian population based on age and sex, shedding light on the impact of pericardial diseases on public health outcomes. Methods  This is a retrospective time-series analysis of pericardial disease mortality rates in Brazil (2000-2022). Data was obtained from the Department of Informatics of the Unified Health System (DATASUS), and the 10th edition of the International Classification of Diseases (ICD-10) codes: I30, I31, and I32 were included for analysis. We gathered population and demographic data categorized by age range and sex from the Brazilian Institute of Geography and Statistics (IBGE). Subsequently, we computed the age-standardized mortality rate per 100,000 individuals and assessed the annual percentage changes (APCs) and average annual percentage changes (AAPCs) using joinpoint regression, along with their corresponding 95% confidence intervals (CIs). Results  In terms of mortality trends based on sex, overall mortality rates remained stable for males and combined sexes over the study period. However, there was a notable increase in mortality rates among females (AAPC=1.18), particularly between 2020 and 2022, with a significant APC of 27.55. Analyzing pericardial diseases across different age groups (20 to 80 years and above), it wasobserved that mortality rates significantly increased in the 70-79 and 80 years and above age groups throughout the study period (AAPC=1.0339 and AAPC=3.4587, respectively). These two age groups experienced the highest significant rise in mortality between 2020 and 2022. Other age groups did not exhibit a significant change in AAPC. Conclusions  This comprehensive analysis spanning two decades (2000-2022), examined the mortality trends of pericardial diseases in Brazil and revealed relative stability overall. Males exhibited an overall higher mortality number due to pericardial diseases; however, females showed the most significant increase in mortality trend throughout the whole period. In the first segment (2000-2015), mortality rose across all cohorts, which was attributed to substandard healthcare facilities and infectious diseases like tuberculosis. The second segment (2016-2020) saw a decline in mortality, likely due to improved healthcare, particularly the increased availability of echocardiograms. However, the third segment (2020-2022) witnessed a sharp rise in mortality, coinciding with the COVID-19 pandemic, with post-COVID-19 symptoms, particularly pericarditis. Pericarditis-related death rates declined compared to pericardial effusion, and mortality rates correlated directly with age, with older cohorts experiencing higher mortality due to increased comorbidities, and decline in health and immunocompetency.

Pericardial Tuberculosis in a Non-endemic Region Presenting as a Persistent Upper Respiratory Tract Infection With Negative Serology, Bronchial Washings, and Pleural Aspirate

This paper reports on the unlikely case of a 68-year-old man presenting with a non-resolving, mild lower respiratory tract infection, subsequently diagnosed with pericardial tuberculosis (TB) in the absence of TB risk factors and with negative TB serology. Pericardial and pleural effusions were found incidentally on CT pulmonary angiogram, with a small pericardial effusion without tamponade seen on the echocardiogram. During his three-month inpatient stay, the patient was rarely very unwell, though no treatment led to clinical and biochemical resolution of symptoms. Later deterioration prompted another echocardiogram, which found a moderate-sized pericardial effusion, septal bounce, and new regional wall motion abnormalities. To avert the impending cardiac tamponade, the patient underwent pericardiectomy, which provided a tissue diagnosis of TB. Pericardial TB is extremely uncommon, especially outside of TB endemic regions, though it is well described. This case is especially noteworthy, as serology, bronchial washings, and pleural aspirate had been negative for TB though a Quantiferon test was positive. The diagnosis was only confirmed after pericardiectomy. The patient was subsequently treated with anti-TB therapy, with a good clinical response. This case highlights diagnostic challenges and strategies for investigating and managing similar complex scenarios, particularly in non-endemic settings.

Cardiovascular Outcomes Associated With Exposure To Radiation Therapy In Thoracic Malignancies: An Insight Study Using the National Inpatient Database

Background Thoracic irradiation is a widely used therapeutic and palliative treatment option for thoracic neoplasms. However, short- and long-term cardiovascular adverse effects of radiation exposure remain a major concern. The short-term adverse effects are observed within months of exposure such as pericardial diseases; meanwhile, the long-term complications are usually insidious and manifest over decades, such as congestive heart failure, coronary artery disease, cardiomyopathy, conduction disorders, constrictive pericarditis, and valvular heart disease. Hence, long-term cardiovascular adverse effects are challenging to predict, and the association with radiation exposure remains difficult to establish. Methodology This retrospective, observational study was conducted using data from the National Inpatient Sample (NIS) database from 2016 to 2019. Adult patients with primary thoracic malignancies who underwent radiation therapy (RT) were defined using principal and secondary International Classification of Diseases, Tenth Revision codes. Other malignancies that can be treated with RT and all secondary malignancies were excluded from the primary comparison group. Cardiac outcomes were defined as the prevalence of congestive heart failure, coronary artery disease, cardiomyopathy, conduction disorders, pericardial diseases, and valvular heart diseases in the primary group. The multivariate logistic and the linear regression analyses were used to adjust for confounders. Results When compared to the general population, adults with thoracic malignancies exposed to RT had higher odds of developing chronic pericarditis (adjusted odds ratio (aOR) = 2, 95% confidence interval (CI) = 1.9-2.2, p < 0.001), acute pericarditis (aOR = 2.3, 95% CI = 1.9-2.9, p < 0.001), constrictive pericarditis (aOR = 2.8, 95% CI = 2.1-3.7, p < 0.001), conduction disorders (aOR = 1.3, 95% CI = 1.2-1.35, p < 0.001), coronary artery disease (aOR = 1.24, 95% CI = 1.2-1.27, p < 0.001), heart failure (aOR = 1.44, 95% CI = 1.4-1.5, p < 0.001), and valvular heart disease (aOR = 1.37, 95% CI = 1.3-1.4, p < 0.001). There was no difference in the odds of developing cardiac arrest (aOR = 1, 95% CI = 0.9-1.10, p = 0.6) or acute myocardial infarction (aOR = 1.1, 95% CI = 1-1.15, p < 0.001). When compared to adults with thoracic malignancies not exposed to RT, adults with thoracic malignancies who were exposed to RT had higher odds of developing acute myocardial infarction (aOR = 1.14, 95% CI = 1.1-1.18, p < 0.001), chronic pericarditis (aOR = 1.3, 95% CI = 1.2-1.3, p < 0.001), acute pericarditis (aOR = 1.6, 95% CI = 1.2-2.1, p < 0.001), constrictive pericarditis (aOR = 2.2, 95% CI = 1.5-3.2, p < 0.001), conduction disorders (aOR = 1.1, 95% CI = 1.08-1.13, p < 0.001), coronary artery disease (aOR = 1.14, 95% CI = 1.12-1.16, p < 0.001), heart failure (aOR = 1.2, 95% CI = 1.17-1.23, p < 0.001), and valvular heart disease (aOR = 1.3, 95% CI = 1.2-1.35, p < 0.001). The odds were similar between the two groups for developing cardiac arrest (aOR = 0.86, 95% CI = 0.8-0.98, p = 0.05). Conclusions Adults with thoracic malignancies who were treated with RT have higher odds of developing chronic pericarditis, acute pericarditis, constrictive pericarditis, conduction disorders, coronary artery disease, heart failure, and valvular heart disease while similar odds of developing cardiac arrest or acute myocardial infarction compared to the general adult population.

A Rare First Presentation of Hodgkin's Lymphoma: Symptomatic Pericardial Effusion

Symptomatic pericardial effusion occurring as the initial manifestation of Hodgkin's lymphoma is exceedingly uncommon, and there are limited documented instances in the available literature. Pericardial effusion can present various differential diagnoses, and among these, malignancy is an important yet less frequently encountered cause. A heightened level of suspicion is crucial for establishing an accurate diagnosis, particularly when the patient's clinical course deviates from the anticipated trajectory. Through this case, we aim to emphasize the significance of considering lymphoproliferative diseases as a pertinent possibility in the differential diagnosis of pericardial effusion. Additionally, we underscore the importance of promptly reaching a diagnosis, as it can help prevent severe complications and enhance the patient's prognosis.

Cardiac magnetic resonance imaging of pericardial diseases: a comprehensive guide

Cardiac magnetic resonance (CMR) imaging has been established as a valuable diagnostic tool in the assessment of pericardial diseases by providing information on cardiac anatomy and function, surrounding extra-cardiac structures, pericardial thickening and effusion, characterization of pericardial effusion, and the presence of active pericardial inflammation from the same scan. In addition, CMR imaging has excellent diagnostic accuracy for the non-invasive detection of constrictive physiology evading the need for invasive catheterization in most instances. Growing evidence in the field suggests that pericardial enhancement on CMR is not only diagnostic of pericarditis but also has prognostic value for pericarditis recurrence, although such evidence is derived from small patient cohorts. CMR findings could also be used to guide treatment de-escalation or up-titration in recurrent pericarditis and selecting patients most likely to benefit from novel treatments such as anakinra and rilonacept. This article is an overview of the CMR applications in pericardial syndromes as a primer for reporting physicians. We sought to provide a summary of the clinical protocols used and an interpretation of the major CMR findings in the setting of pericardial diseases. We also discuss points that are less well clear and delineate the strengths and weak points of CMR in pericardial diseases.

A Case of Pure Pericarditis Associated With COVID-19: Application of Classical Clinical Evaluation for Differential Diagnosis

Pericarditis of varying severity is being recognized as a rare complication of the COVID-19 infection. We present a patient with an electrocardiogram (EKG) and physical exam findings that initially seemed to most likely be pericarditis related to the COVID-19 infection. The differential diagnosis was a bit difficult because it included ST-segment elevation myocardial infarction (STEMI) due to some EKG changes and early repolarization changes that were rather robust. Treatment options for STEMI could cause severe harm if the process turned out to be pericarditis. Treatment options for pericarditis could cause severe harm if the process turned out to be STEMI. And treatment options for early repolarization might be no treatment at all, which could cause harm if the process turned out to be STEMI or pericarditis. In this case, a correct diagnosis was very important to ensure a good clinical outcome. We would like to share our thought processes in the management of this case.

COVID-19 Vaccine-Induced Myocarditis: A Systemic Review and Literature Search

Myocarditis is one of the complications reported with COVID-19 vaccines, particularly both Pfizer-BioNTech and Moderna vaccines. Most of the published data about this association come from case reports and series. Integrating the geographical data, clinical manifestations, and outcomes is therefore important in patients with myocarditis to better understand the disease. A thorough literature search was conducted in Cochrane library, PubMed, ScienceDirect, and Google Scholar for published literature till 30 March 2022. We identified 26 patients eligible from 29 studies; the data were pooled from these qualifying case reports and case series. Around 94% of patients were male in this study, the median age for onset of myocarditis was 22 years and 85% developed symptoms after the second dose. The median time of admission for patients to hospitals post-vaccination was three days and chest pain was the most common presenting symptom in these patients. Most patients had elevated troponin on admission and about 90% of patients had cardiac magnetic resonance imaging (CMR) that showed late gadolinium enhancement. All patients admitted with myocarditis were discharged home after a median stay of four days. Results from this current analysis show that post-mRNA vaccination myocarditis is mainly seen in young males after the second dose of vaccination. The pathophysiology of vaccine-induced myocarditis is not entirely clear and late gadolinium enhancement is a common finding on CMR in these patients that may indicate myocardial fibrosis or necrosis. Prognosis remains good and all patients recovered from myocarditis, however further studies are advisable to assess long-term prognosis of myocarditis.

A Delayed Case of Pericarditis Following Recovery From COVID-19 Infection

Pericarditis is a rare cardiac complication of coronavirus 19 (COVID-19) infection. Recent case reports describe severe sequelae of pericarditis, including cardiac tamponade, developing within days of initial COVID-19 symptoms. We present a case of pericarditis with slower onset and milder symptoms, developing over a period of a few weeks in an immunocompetent male who recovered from COVID-19 several months earlier. A 65-year-old male presented to an emergency department several times for one week of worsening chest and neck symptoms, along with fever. He had been symptom-free after a three-day course of cough, myalgias, and fever with positive COVID-19 testing, approximately 70 days earlier. He was ultimately admitted for fever and pericarditis with an associated pericardial effusion and positive PCR testing for COVID-19. Pericarditis should be considered in the differential diagnosis for patients with COVID-19 and unexplained persistent chest symptoms. The possibility of recurrent or atypical latent infection should additionally be considered in the months following the initial COVID-19 infection. Bedside ultrasound may facilitate early diagnosis and management of COVID-19 associated pericarditis.

Age- and sex-based differences in patients with acute pericarditis

BACKGROUND

Acute pericarditis has a wide spectrum of clinical presentations largely depending on underlying aetiologies. We assessed the role of age and sex in the clinical features and outcome of acute pericarditis.

MATERIALS AND METHODS

A total of 240 consecutive patients hospitalized with a first episode of acute pericarditis were included. At baseline demographics, clinical features, laboratory and imaging findings and medical therapy were recorded. Patients were followed up for at least 18 months for complications. Data comparisons were performed according to sex and age (≤60 or >60 years).

RESULTS

The male/female ratio was 1.42, and 56% of patients were >60 years. Younger patients depicted more often chest pain (P = .001), fever and rubs (P < .001 for both), ST elevation and PR depression (P = .032 and .009, respectively), higher CRP values (P = .009) and less often dyspnoea (P = .046) and pericardial effusion (P = .036). Moreover, they received less often glucocorticoids (P < .001) and depicted less atrial fibrillation (P = .003) and a higher rate of recurrent pericarditis (P = .013). After multivariate adjustment for confounders, age >60 years remained an independent predictor for a lower risk of recurrent pericarditis (hazard ratio 0.60, 95% CI: 0.39-0.96, P = .033). Regarding sex, females were older (P = .007), showed less often ST elevation and PR depression (P < .001 and .002, respectively) and had a higher baseline heart rate (P = .02). Sex was not associated with recurrent pericarditis risk.

CONCLUSIONS

Patients with acute pericarditis have distinct presenting clinical, biochemical and prognostic features according to age and sex. Awareness of such differences is important for clinical decision-making.

Rapidly Developing Methicillin-Resistant Staphylococcus Aureus Pericarditis and Pericardial Tamponade

Methicillin-resistant staphylococcus aureus (MRSA) pericarditis is a rare life-threatening infection. A 46-year-old female with hypertension, acquired immunodeficiency syndrome (AIDS) and recurrent neck abscesses, presented with a neck abscess and sepsis. Bloody purulent drainage from the abscess was found and antibiotics were started. Drainage was positive for MRSA. Four days after, course was complicated by acute pericarditis and pericardial tamponade; pericardial fluid was drained and was positive for MRSA. Vancomycin was continued, and aspirin and colchicine were started. Two days later, there was a recurrent pericardial fluid collection with loculation. Surgery was thought to be dangerous in the setting of CD4 count of 12. She was managed conservatively thereafter, with vancomycin, aspirin and colchicine, and was successfully discharged from the hospital.

Etiology of Pericardial Effusion and Outcomes Post Pericardiocentesis in the Western Region of Saudi Arabia: A Single-center Experience

Background Pericardial effusion is the accumulation of blood or excess fluid in the cavity between the heart and the pericardium sac. Pericardial effusion can be caused by several etiologies, including malignant and non-malignant causes. Pericardiocentesis is the gold standard assessment method for pericardial effusion etiology. The aim of this study was to identify the long-term outcome of patients who presented with massive pericardial effusion and underwent pericardiocentesis at King Abdulaziz Medical City, Jeddah, a large tertiary hospital in the western part of Saudi Arabia. Methods This is a single-center retrospective cross-sectional study conducted at King Abdulaziz Medical City Jeddah, Saudi Arabia, between January 2013 to December 2018. Data were collected from patient's charts; the clinical and echocardiographic findings, alongside with pericardial fluid analysis, were collected. Procedure and patients outcomes were obtained and reported. Results Of the 107 patients with pericardial effusion, 39 patients had moderate to severe pericardial effusion requiring pericardiocentesis. The mean age was 52 years, and 56.4% were females. The most common chronic disease was hypertension and the presence of metastasis. The most common cause of pericardial effusion was a malignancy. A majority of patients had severe pericardial effusion. Many patients had tamponade (69.6%). Patients with malignant pericardial effusion had a median survival of 54 days. Conclusion Etiologies of pericardial effusion requiring drainage depend on the population studied. Patients with malignant effusions have worse outcomes than non-malignant effusion. Pericardiocentesis is required to ascertain the cause and risk-stratify patients.

Recent advances in the management of pericardial diseases

Pericardial diseases are relatively common in clinical practice either as isolated diseases or part of an underlying or systemic disease. Recent advances in the diagnosis and treatment have greatly improved the clinical management and lead to consensus documents on multimodality imaging and new guidelines on the diagnosis and therapy of pericardial diseases. The aim of the present paper is to summarize available evidence in order to provide an updated and comprehensive review on the recent advances in the management of pericardial diseases.
