Opisowe badanie krążących genów lub białkowych biomarkerów zapalnych oraz parametrów bioimpedancji w populacji pacjentów hospitalizowanych z powodu niewyrównanej niewydolności serca z zachowaną lub nieznacznie obniżoną funkcją serca (BIOFEVIP)
Profil zapalny u pacjentów hospitalizowanych z powodu niewydolności serca z zachowaną lub lekko obniżoną frakcją wyrzutową oraz jego korelacja z parametrami bioimpedancji i innymi biomarkerami o wartości prognostycznej
The goal of this observational study is to determine whether changes in the inflammatory profile of heart failure patients can help identify those who may have a worse prognosis or who might benefit more from specific treatments. In addition, we aim to explore whether certain genes or gene mutations are related to a higher risk of future cardiovascular problems.
Heart failure continues to be a major cause of hospital admissions and death in our society. Because of this, it is very important for healthcare professionals to identify which patients are at higher risk of complications, so that we can provide the best possible treatment and follow-up. One method we use to help predict how the disease may evolve is the study of biomarkers, which are measurable biological substances that can help detect, monitor, or treat illnesses in a more personalized way.
In this study, the investigators will measure mainly inflammatory biomarkers that will be analyzed from a blood sample taken during hospital stay after being diagnosed with heart failure with preserved or mildly reduced ejection fraction. Any important health events that happen during the next six months after patients are discharged from hospital will also be recorded.
In addition, it is known that more than 2,000 diseases are known to be caused by changes in specific genes. In the case of cardiomyopathies-heart muscle diseases that can lead to heart failure-genetic causes vary depending on the type, and studies suggest that between 10% and 50% of cases may have a genetic origin. Identifying genetic markers linked to heart failure with preserved or mildly reduced ejection fraction may help improve prevention, treatment, and risk assessment, as some genetic changes may be associated with repeated cardiovascular events. By studying not only circulating biomarkers but also genetic factors, the investigators hope to better understand whether certain gene alterations may increase a person's tendency to experience additional heart-related events.
This is an observational study, which means that medical care and treatment will be exactly the same whether patients choose to participate or not. Participation involves allowing researchers to collect relevant information from medical records and agreeing to the collection of two or three small additional blood samples for research purposes. These samples will be used to measure the biomarkers and to analyze genes in the white blood cell fraction obtained from the same tubes.
