AI Article Synopsis
- The study analyzed nearly 50,000 case reports to investigate the causes and outcomes of heart failure, identifying a significant portion linked to non-cardiovascular diseases.
- Among the 2,893 relevant cases studied, 67.5% had cardiovascular issues while 32.5% stemmed from non-cardiovascular conditions, with a higher mortality rate observed in the latter group (17.8% vs. 10.8%).
- Diseases like pulmonary tumor thrombotic microangiopathy, multiple myeloma, and amyloidosis were highlighted as major contributors to heart failure deaths, emphasizing the need for cardiologists to consider broader internal medicine contexts.
Article Abstract
Objective To examine case reports presented at the Regional Meeting of the Japanese Society of Internal Medicine in order to clarify the underlying disease and prognosis of heart failure, which is often caused by non-cardiovascular diseases. Methods We examined 49,693 case reports from the Japanese Society of Internal Medicine database. A total of 2,893 reports were included after excluding 46,022 reports that did not include the term "heart failure" and 778 reports with no indications of symptoms of heart failure. We assessed each patient's basal disease, and according to the abstracts, we reported their prognosis as dead or alive. Results Of the 2,893 reports included, 1,952 (67.5%) and 941 (32.5%) had cardiovascular and non-cardiovascular diseases as the causes, respectively; these cases were attributed to 725 different diseases, 196 (27.0%) and 529 (73.0%) of which were cardiovascular and non-cardiovascular diseases, respectively. In addition, 91 different side effects were identified. The percentage of cases of heart failure-related mortality was significantly higher among the patients with non-cardiovascular diseases than in those with cardiovascular diseases (17.8% vs. 10.8%; p <0.001). Of the diseases reported as causes of heart failure in more than 10 reports, pulmonary tumor thrombotic microangiopathy (87%), multiple myeloma (50%), and amyloidosis (47%) accounted for the highest percentages of heart failure-related mortality. Conclusion Because heart failure is often caused by non-cardiovascular diseases, a broad study of case reports on internal medicine is important for cardiologists.

Metabolic dysfunction-associated fatty liver disease (MAFLD) is a major cause of liver-related morbidity and mortality, contributing to both cardiovascular and non-cardiovascular deaths. The Body Roundness Index (BRI) and Systemic Immune-Inflammation Index (SII) have emerged as predictors of adverse outcomes in metabolic diseases. This study investigates the association between BRI, SII, and mortality risk in MAFLD patients.

Background And Objectives: Over the last two decades, reductions in cardiovascular (CV) and cerebrovascular events for patients with atrial fibrillation (AF) have been observed, but the non-cardiovascular rates have increased. Early initiation of oral anticoagulation helps reduce AF complications; however, the impact of delayed cardiology care after referral by a Primary Care Physician (PCP) is unknown. The aim of our study is to investigate the association between the elapsed time to cardiology care following a PCP referral and one-year outcomes among patients with AF and analyses gender-specific differences in these outcomes.

Reactive oxygen species (ROS) are generated predominantly during cellular respiration and play a significant role in signaling within the cell and between cells. However, excessive accumulation of ROS can lead to cellular dysfunction, disease progression, and apoptosis that can lead to organ dysfunction. To overcome the short half-life of ROS and the relatively small amount produced, various imaging methods have been developed, using both endogenous and exogenous means to monitor ROS in disease settings.

Methods: This retrospective analysis was conducted on 71 patients with end-stage kidney disease who underwent hemodialysis at Beilun District People's Hospital from September 2021 to September 2022. The patients were divided into two groups based on the occurrence of CEs: a cardiovascular event group and a non-cardiovascular event group.

Purpose Of Review: Heart failure (HF) is often accompanied by a constellation of comorbidities, leading to diverse patient presentations and clinical trajectories. While traditional methods have provided valuable insights into our understanding of HF, network medicine approaches seek to leverage these complex relationships by analyzing disease at a systems level. This review introduces the concepts of network medicine and explores the use of comorbidity networks to study HF and heart disease.
