AI Article Synopsis
- The study investigates whether midregional pro-adrenomedullin (MR-proADM) levels can predict cardiovascular issues in a general population over a 14-year period.
- MR-proADM was analyzed alongside other natriuretic peptides in a sample of 8,444 individuals, utilizing advanced statistical methods to assess its predictive value.
- Results showed that high MR-proADM levels were linked to increased risks of death, stroke, major adverse cardiac events, and heart failure, and adding MR-proADM to traditional risk factors improved the accuracy of heart failure predictions.
Article Abstract
Introduction: To examine whether midregional pro-adrenomedullin (MR-proADM) plasma concentrations predict incident cardiovascular outcomes in the general population. Natriuretic peptides (N-terminal pro-brain natriuretic peptide (NT-proBNP), B-type natriuretic peptide (BNP), and midregional pro-atrial natriuretic peptide (MR-proANP)) were analyzed for comparison.
Material And Methods: MR-proADM plasma concentrations and those of the natriuretic peptides were determined in 8444 individuals of the FINRISK 1997 cohort. Patients were followed for 14 years (median). Cox regression analyses, discrimination, and reclassification analyses adjusting for Framingham risk factors were performed to evaluate the additional benefit from MR-proADM.
Results: MR-proADM concentrations significantly predicted all-cause death (hazard ratio highest quintile versus lowest 1.18, 95% confidence interval 1.08-1.28), stroke (1.20, 1.05-1.38), major adverse cardiac events (MACE) (1.27, 1.17-1.37), and heart failure (1.67, 1.49-1.87). MR-proADM remained associated with MACE, death, and heart failure even after additional adjustment for NT-proBNP and C-reactive protein. Adding MR-proADM to the Framingham risk factors significantly improved discrimination (P < 0.001 for C-statistics and integrated discrimination improvement) and risk reclassification for heart failure (net reclassification improvement 12.12%, P < 0.001).
Conclusions: In a healthy general population sample of the FINRISK 1997 cohort MR-proADM significantly predicted all-cause death, MACE, and especially heart failure even beyond NT- proBNP. It also improved risk reclassification for heart failure.

Lipid phosphate phosphatase 3 (LPP3) is a membrane-bound enzyme that hydrolyzes lipid phosphates including the bioactive lipid, lysophosphatidic acid (LPA). Elevated circulating LPA production and cellular LPA signaling are implicated in obesity-induced metabolic and cardiac dysfunction. Deletion of LPP3 in the cardiomyocyte increases circulating LPA levels and causes heart failure and mitochondrial dysfunction in mice.

Clarifying the inceptive pathophysiology of hypertensive heart disease helps to impede the disease progression. Through coarctation of the infrarenal abdominal aorta (AA), we induced hypertension in minipigs and evaluated physiological reactions and morpho-functional changes of the heart. Moderate aortic coarctation was achieved with approximately 30 mmHg systolic pressure gradient in minipigs.

Introduction: Heart failure (HF) is a chronic condition with an unpredictable trajectory, making effective communication between patients and healthcare providers crucial for optimizing outcomes. This study aims to investigate and compare the communication needs regarding HF trajectory and palliative care between patients and healthcare providers and to identify factors associated with the communication needs of patients with HF.
Methods: A cross-sectional study design was employed, involving 100 patients with HF and 35 healthcare providers.

Objective: To investigate the association of noncigarette tobacco products with cardiovascular health outcomes.
Design, Setting, And Participants: This cohort study was conducted within the Cross Cohort Collaboration Tobacco Working Group by harmonizing tobacco-related data and conducting a pooled analysis from 15 US-based prospective cohorts with data on the use of at least 1 noncigarette tobacco product ranging between 1948 and 2015.
