Abstract: Despite the fact that obesity has long been recognized as a risk factor for cardiovascular disease, the mortality rate of heart failure (HF) patients with cachexia is still high. Several studies have been conducted to investigate the association between cachexia and mortality in HF patients. However, the research results vary, as do the diagnostic criteria employed to assess cachexia. This meta-analysis aimed to conclusively summarize the association between cachexia and mortality in HF patients. The data were obtained from prospective or retrospective cohort studies with full texts in English or Indonesian and keywords related to "cachexia," "heart failure," and/ or "mortality". Studies that did not assess mortality in HF patients with cachexia and had no full text accessible were omitted. A literature search was conducted through four databases (PubMed, Web of Science, Scopus, and SAGE Journals) using keywords, reference searches, and/ or other methods on April 2022 in accordance with the Preferred Reported Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data from the selected studies were presented and analyzed using qualitative and quantitative synthesis methods. The Newcastle-Ottawa Scale (NOS) was used to assess the risk of bias in the selected cohort studies. The qualitative synthesis contained nine studies, whereas the quantitative synthesis (meta-analysis) included six studies. Cachexia was found in 16.0% of the 4,697 patients studied. During the 180-1,876-day follow-up period, 33.0% of the patients died, with a mortality rate of 38.8% among the patients with cachexia. The pooled analysis revealed cachexia to be a significant predictor of mortality in HF patients (hazard ratio (HR)=3.84; 95% CI=2.28-6.45; p<0.00001), but with significant heterogeneity (p<0.00001; I2=88%). In conclusion, cachexia worsens HF prognosis.
