Heart Failure Hospitalization

The goal of this prospective, multicenter, non-randomized observational study is to better identify and understand periprocedural myocardial injury among adults undergoing percutaneous coronary intervention (PCI) for stable coronary artery disease or stabilized non-ST-elevation acute coronary syndrome. The main questions it aims to answer are: * Can a clinical criteria checklist identify patients with an increased likelihood of cardiac biomarker elevation following PCI? * Are positive clinical criteria and different post-PCI levels of troponin I, troponin T, and CK-MB associated with all-cause mortality or hospitalization for heart failure at one year? Researchers will compare participants with a positive clinical criteria checklist with those with a negative checklist to assess differences in post-PCI biomarker elevations and one-year clinical outcomes. Outcomes will also be compared between participants discharged on the same day and those hospitalized overnight. Participants will: * Undergo PCI using commercially approved devices according to local standards of care. * Have blood samples collected before and after PCI to measure cardiac biomarkers. * Have relevant clinical and PCI procedural information collected, including completion of a clinical criteria checklist by the study team before discharge. * Be followed for one year to determine whether they have died from any cause or been hospitalized for heart failure.

Heart failure hospitalization is associated with a high risk of early readmission and mortality. There is an unmet clinical need for low-burden, non-invasive methods to better understand congestion and hemodynamic status during hospitalization. This observational study evaluates the association between non-invasive measurements obtained with the Acorai Device 1.0 and clinical data collected during hospitalization and up to 90 days after discharge in patients admitted with heart failure. The device performs short, non-invasive recordings that collect physiological signals from the thoracic region without influencing clinical care. Participants will undergo daily recordings during hospitalization. Clinical information and outcomes, including heart failure hospitalization and all-cause mortality within 90 days after discharge, will be collected from medical records. The study aims to explore relationships between non-invasive sensor measurements and clinical outcomes in hospitalized heart failure patients.

This clinical trial aims to determine whether a ReDS-guided treatment strategy is superior to the current standard of care for adults hospitalized with heart failure. Additionally, the study will evaluate the safety and cost-effectiveness of this approach. The study seeks to answer the following key questions: 1. Does the ReDS-guided strategy reduce the risk of cardiovascular events during the first month following hospital discharge? 2. What is the safety profile of this treatment strategy? Researchers will compare the ReDS-based strategy against the current standard of care. All participants will: * Undergo daily assessments using the ReDS device throughout their hospitalization. * Attend two follow-up visits post-discharge, scheduled at 2 weeks and 30 days.
