Background: Diabetes is a common comorbid condition in patients with heart failure and is strongly associated with poor outcomes. Patients with heart failure who have diabetes are more likely to be obese than are those without diabetes. Obesity is positively associated with survival in patients with heart failure, but how comorbid diabetes influences the relationship between obesity and favorable prognosis is unclear.
Objective: To explore whether the relationship between body mass index and survival differs between patients with heart failure who do or do not have diabetes.
Methods: The sample consisted of 560 ambulatory patients with heart failure (mean age, 66 years; mean body mass index, 32; diabetes, 41%). The association between body mass index and all-cause mortality was examined by using multivariate Cox proportional hazards regression after adjustments for covariates.
Results: In patients without diabetes, higher body mass index was associated with a lower risk for all-cause mortality after adjustments for covariates (hazard ratio, 0.952; 95% CI, 0.909-0.998). In patients with diabetes, body mass index was not predictive of all-cause death after adjustments for covariates.
Conclusion: Obesity was a survival benefit in heart failure patients without comorbid diabetes but not in those with comorbid diabetes. The mechanisms underlying the difference in the relationship between obesity and survival due to the presence of diabetes in patients with heart failure need to be elucidated.

During qualification for mechanical circulatory support, the comprehensive assessment of a patient's mental state is an integral element of the overall medical evaluation. It encompasses a range of psychosocial issues, and as such provides information helpful in the selection of a suitable candidate for the required treatment, and sometimes identifies contraindications to it. It allows ensuring that the patient meets expectations regarding both mental health stability and adherence to medical recommendations.

Background: Atrial fibrillation (AF) is the most prevalent arrhythmia encountered in clinical practice. Triglyceride glucose index (Tyg), a convenient evaluation variable for insulin resistance, has shown associations with adverse cardiovascular outcomes. However, studies on the Tyg index's predictive value for adverse prognosis in patients with AF without diabetes are lacking.

Aims: To study differences in cardiovascular prevention and hypertension management in primary care in men and women, with comparisons between public and privately operated primary health care (PHC).
Methods: We used register data from Region Stockholm on collected prescribed medication and registered diagnoses, to identify patients aged 30 years and above with hypertension. Age-adjusted logistic regression was used to calculate odds ratios (ORs) with 99% confidence intervals (99% CIs) using public PHC centers as referents.

Background: Obesity is a risk factor for heart failure (HF) development but is associated with a lower incidence of mortality in HF patients. This obesity paradox may be confounded by unrecognized comorbidities, including cachexia.
Methods: A retrospective assessment was conducted using data from a prospectively recruiting multicenter registry, which included consecutive acute heart failure patients.

HFpEF is a prevalent and complex type of heart failure. The concurrent presence of conditions such as obesity, hypertension, hyperglycemia, and hyperlipidemia significantly increase the risk of developing HFpEF. Mitochondria, often referred to as the powerhouses of the cell, are crucial in maintaining cellular functions, including ATP production, intracellular Ca regulation, reactive oxygen species generation and clearance, and the regulation of apoptosis.
