Severe Obesity and Heart Failure

American Registry of Ambulatory or acutely decompensated heart failure (AMERICCAASS Registry): First 1000 patients

“…However, the rate of obesity is much lower, which could be related to most of the large cohorts being in North America, where obesity levels exceed those of the general population. 15,16 HF is associated with a high burden of cardiac and noncardiac complications, even higher in patients with diabetes mellitus. 17 This comorbidity has a prevalence that varies in different registries; in our study, it was found to be 28%, which is close to that reported by large multinational studies, such as the "Global Study of Congestive Heart Failure" (G-CHF), which reports a prevalence of diabetes mellitus of 31% in the population with HF 18 and the "International Registry to Evaluate Medical Practice with Longitudinal Observation for the Treatment of Heart Failure" (REPORT-HF), which described a prevalence of 31% in Central and South America.…”

Nutritional management during critical illness in those with previous obesity surgery

“…This condition is mostly related to decreased intake of protein, but triggering factors such as vomiting and dysphagia, as well as a small alimentary limb (<250-300 cm) are also associated risk factors [11]. In obese patients with cardiac failure, the excess weight was directly correlated with cardiogenic shock and length of hospital stay, as well as, with increased hospital costs [12]. General obese critically ill patients also present worse outcomes.…”

“…Although the literature has claimed the obese paradox to explain better survival under several conditions, such as renal and cardiac failure, this might only be a surrogate of better nutritional conditions for those who still had not lost most of their previous weight, as body mass index was the predicting variable alone. In a recent study, Aguillar-Gallardo et al [12] presented the results of a retrospective cohort of hospitalized adults for heart failure, and they showed that among over two million patients, there was a decreased mortality in nonsevere obesity, while, in the severe obese mortality was increased, but when other outcomes such as cardiogenic shock and length of hospital stay were considered there was a linear correlation between all levels of obesity and negative outcomes. In this regard, it is of utmost importance to highlight that BMI indicates only total body mass, which under several disease conditions, particularly those with acute inflammation, may be marked by severe loss of muscle mass and poor muscle quality due to fat deposits, hampering poor prognosis.…”

Is time‐restricted eating (8/16) beneficial for body weight and metabolism of obese and overweight adults? A systematic review and meta‐analysis of randomized controlled trials

“…Furthermore, novel data indicate that obesity and impaired metabolic health are important risk factors for severe coronavirus disease 2019 (Stefan, 2022;Stefan et al, 2021). Obesity has a high global prevalence, and it is not an exaggeration to call it an epidemic (Aguilar-Gallardo et al, 2022).…”

“…Furthermore, novel data indicate that obesity and impaired metabolic health are important risk factors for severe coronavirus disease 2019 (Stefan, 2022; Stefan et al, 2021). Obesity has a high global prevalence, and it is not an exaggeration to call it an epidemic (Aguilar‐Gallardo et al, 2022). A study by Ward et al (2019) suggested that by 2030, nearly one in every two US adults will have obesity, and severe obesity is estimated to be found in close to 25% of US adults.…”
