CHF associated with high mortality risk in malnourished patients: Study
In malnourished patients, chronic heart failure (CHF) is associated with increased mortality risk, according to a new study published in the Plos one.
Malnutrition has a high occurrence in patients with chronic heart failure (CHF). The prevalence of malnutrition and its impact on all-cause mortality in patients with chronic heart failure (CHF) were assessed using a meta-analysis. Heart failure (HF) is an aggregate clinical syndrome, where various structural or functional diseases lead to ventricular filling and/or ejection dysfunction. The heart is unable to maintain sufficient cardiac output to fulfill the requirements of energy metabolism and adapt to the amount of venous return. Therefore, HF is the end stage of various cardiovascular diseases.
PubMed, Embase, the Cochrane Library, Web of Science, Medline, CBM, CNKI, WANFANG DATA, and VIP databases were searched to collect cross-sectional and cohort studies on malnutrition, and the prevalence and all-cause mortality of patients with chronic heart failure (CHF) were determined. The time of retrieval was from the database establishment to May 2021. Two researchers independently performed screening of the literature, data extraction and assessed the risk of bias in the included studies. Then Stata 16.0 software was used for meta-analysis.
