to assess the evolution of fragmented QRS (fQRS) and NT-proBNP levels during myocardial infarction (MI). Among 511 patients, 205 (40.1%) had fQRS, with 54 (26.3%) developing de novo fragmentation during hospitalization. NT-proBNP levels were significantly higher in the fQRS+ group compared with the fQRS- group (1555 vs. 796 pg/ml, p < 0.001). NT-proBNP levels were higher in patients with de novo fragmentation than in those without (2852 vs. 1370 pg/ml, p = 0.011). The incidence of major adverse cardiovascular events was notably higher in fQRS+ patients compared with fQRS- patients (p = 0.001). In acute MI, there was a significant association between fQRS and NT-proBNP levels, with higher NT-proBNP levels observed in those with de novo fQRS compared with those without.

Pro-adrenomedullin as an independent predictive biomarker for heart failure in atrial fibrillation and flutter.
ESC Heart Fail

Department of Cardiology, Beijing Anzhen Hospital, Capital Medical University, National Clinical Research Center for Cardiovascular Diseases, Beijing, China.
Aims: This study aimed to investigate potential biomarkers for predicting incident heart failure (HF) in patients with atrial fibrillation and flutter (AF and AFL), utilizing proteomic data from the UK Biobank Pharma Proteomics Project (UKB-PPP).
Methods: This study analysed data from AF and AFL patients, split into discovery (n = 1050) and replication (n = 305) cohorts. Plasma biomarkers were screened using a multivariable-adjusted Cox proportional hazards model.
DESCRIPTION OF THE CLINICAL AND RADIOLOGICAL CHARACTERISTICS OF PULMONARY EMBOLISM IN COVID-19 VERSUS NON COVID-19 PATIENTS: A MULTICENTRIC CROSS-SECTIONAL STUDY OVER A 24-MONTH PERSPECTIVE.

Medicine II Unit, ASST Santi Paolo e Carlo, Department of Health Sciences, University of Milan, Milan.
Background: COVID-19 is associated with intense systemic inflammation and abnormal coagulation profile leading to an increased incidence of pulmonary embolism (PE). This study investigates whether PE in COVID-19 patients has different clinical, laboratory and radiological characteristics when compared to traditional PE in COVID negative patients.
Methods: We conducted an observational, multicentric, cross-sectional study on consecutive patients diagnosed with PE at admission or during hospital stay from February 21 2019 to February 20 2021.
Predicting Heart Rate at the Anaerobic Threshold Using a Machine Learning Model Based on a Large-Scale Population Dataset.

Department of Cardiovascular Medicine, Sakakibara Heart Institute, Tokyo 183-0003, Japan.
For effective exercise prescription for patients with cardiovascular disease, it is important to determine the target heart rate at the level of the anaerobic threshold (AT-HR). The AT-HR is mainly determined by cardiopulmonary exercise testing (CPET). The aim of this study is to develop a machine learning (ML) model to predict the AT-HR solely from non-exercise clinical features.

Background: Micronutrient deficiencies are common and play a significant role in the prognosis of many chronic diseases, including heart failure (HF), but their prevalence in HF is not well known. As studies have traditionally focused on causes originating within the intestines, exocrine pancreatic insufficiency (EPI) has been overlooked as a potential contributor. The exocrine pancreas enables the absorption of various (fat-soluble) micronutrients and may be insufficient in HF.

Hypertension is a major risk factor of various cardiac complications, including hypertensive heart disease (HHD). This condition can lead to a number of structural and functional changes in the heart, such as left ventricular hypertrophy, diastolic dysfunction, and, eventually, systolic dysfunction. In the management of hypertensive heart disease, early diagnosis and appropriate treatment are crucial for preventing the progression to congestive heart failure.
