Heart failure (HF) often coexists with non-cardiac comorbidities (NCC), but their association with long-term HF re-hospitalizations is not defined. Using the Lombardy Regional Health Database, that includes >10 million residents, we assessed the risk of re-hospitalization for HF after first HF discharge as a function of NCC, employing age- and sex-adjusted Cox proportional-hazard models. Kaplan Meier curves for HF re-hospitalizations were stratified for number of NCC. End of follow-up was June 30th 2021. Between January 1st 2015 to December 31st 2019, 88,528 consecutive patients were discharged from hospital with a primary diagnosis of HF; over 42.8 ± 18.3 months follow-up, 79,533 HF re-hospitalizations occurred (32.94/100 patient/year). Number of NCC, age, and male sex were significantly associated with re-hospitalization risk. Compared to those without NCC, females and males with >4 NCC had a 3.08 (CI 2.73-3.47) and a 2.62 (CI 2.39-2.87) fold higher risk, respectively. Risk of all-cause death increased with number of NCC (hazard ratio (HR): 1.42 (1.38-1.46) for HF patients with 1-2 NCC, HR: 1.90 (1.82-1.98) for patients with 3-4 NCC, HR: 2.20 (2.01-2.40) for those with HF and >4 NCC), as it did the number of days spent in hospital because of HF (from 19.91±19.25 for patients without NCC to 45.35±33.00 days for those with >4 NCC, p < 0.0001). In conclusion, this study shows that in patients hospitalized with HF, HF re-hospitalizations, all-cause mortality, and time spent in hospital increased with number of NCC. NCC associates with a worse clinical trajectory in patients with HF.
Background and aims: Homocysteine (Hcy) levels are elevated in different conditions, including cardiovascular diseases (CVD), diabetes, and metabolic-associated steatotic liver disease (MASLD). In this observational retrospective study, we analyzed Hcy levels in a population of 901 outpatients, considering its putative etiological role in MASLD.
Methods: A total of 901 outpatients underwent physical and biochemical evaluations. Abdominal and carotid ultrasound were performed to assess liver steatosis, carotid intima-media thickness (IMT) and presence of atherosclerotic plaque.
Results: Hyperhomocysteinemia (HHcy) was identified in 140 subjects (16 %). Patients with HHcy showed glucose metabolism impairment (p < 0.001), altered lipid profile (p < 0.001), low Vitamin D levels (p < 0.0001), increased cardiovascular risk (p < 0.001). We then investigated the relationship between Hcy and MASLD (OR=3.6, p < 0.0001), finding that the relationship remained significant also when accounting for confounding variables (age, sex) (OR=3.2, p < 0.0001). Hcy values were significantly higher (p < 0.0001) in patients with MASLD (n = 78, 29.4 ± 10.1μmol/l) compared to those without MASLD (20.4 ± 4.8 1μmol/l). Furthermore, in MASLD patients we found a direct correlation between Hcy level and waist circumference (r = 0.3, p < 0.001) and an inverse correlation with both HDL-c (r=-0.4, p < 0.001) and Vitamin D levels (r=-0.24, p < 0.05).
Conclusions: Our data suggest an intriguing scenario whereby HHcy is present in patients with MASLD and is associated to lower vitamin D and altered glucose and lipid profile. Thus, considering Hcy levels may help clinicians with the management of patients with increased MASLD risk.
