Summary: This study investigates the function of cardiac Rev-erb in heart diseases and the relationship between cardiac molecular clock dysfunction and the progression of naturally occurring human heart diseases. The researchers found that Rev-erb knockout in mice leads to dilated cardiomyopathy and heart failure. They also discovered the role of cardiac molecular clock in the obesity paradox and found altered temporal patterns of cardiac Rev-erb gene expression in human hearts with dilated cardiomyopathy. The findings suggest that targeting myocardial bioenergetics downstream of Rev-erb may be a potential approach for treating heart failure and dilated cardiomyopathy.

Summary: The paradoxical association between high BMI and better outcome in heart failure patients is examined in this study. The researchers found that malnutrition significantly changes the impact of BMI on prognosis, with obese patients who are also malnourished having a worse outcome compared to well-nourished patients with normal weight.

Summary: The myocardium burns a significant amount of ATP within the mitochondria, crucial for its functions. Mitochondrial dysfunction is linked to a wide range of heart diseases and can contribute to the development of heart failure. Targeting mitochondrial function may be a potential treatment strategy for heart failure.

Summary: In dilated cardiomyopathy (DCM), heart failure occurs due to the stretching and thinning of the heart muscle, resulting in an abnormal cardiac metabolism and energetic inefficiency. The optimal metabolic environment for a failing heart is still unknown and debated. Previous studies have shown intriguing findings in increasing glucose oxidation, but none of the drugs have been tested in large-scale clinical trials. Other studies suggest that increasing fatty acid oxidation and raising ketone body levels may benefit the treatment of metabolic dysfunction in heart failure. Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have shown improvement in cardiac function by increasing ketone body levels, and may provide a potential therapeutic approach. This review aims to identify the best metabolic therapeutic approach for DCM patients and explore the effects of different drugs on cardiac metabolism, with a special focus on SGLT2i.

Summary: The study found that nonfailing hearts generally have higher EAT content compared to end-stage failing hearts, and there is no strong correlation between EAT quantity and BMI in both nonfailing and failing hearts. Atrial EAT is closely correlated with ventricular EAT in both nonfailing and failing hearts.

Summary: Cell death is a significant factor in cardiovascular disease pathophysiology. Ferroptosis, a regulated cell death form characterized by iron overload and lipid hydroperoxide accumulation, is closely associated with various diseases and plays critical roles in cardiomyopathy, myocardial infarction, ischemia/reperfusion injury, and heart failure. Targeting ferroptosis may offer potential novel therapeutic strategies for cardiovascular diseases.

Summary: Myocarditis is an inflammatory disease that can lead to sudden death and chronic heart failure. The molecular mechanisms during the post-myocarditis phase are not well understood. This study suggests that ANKRD1, a stress-responsive protein, may play a role in cardiac remodeling after myocarditis.

Summary: This study aimed to investigate the sex and age differences in soluble ST2 (sST2) levels for various cardiovascular diseases (CVDs). Using ELISA kit, sST2 levels were measured in patients with myocarditis, cardiomyopathy, coronary artery disease (CAD), myocardial infarct (MI), and congestive heart failure (CHF) and compared to controls without CVDs. The results showed that myocarditis occurred in younger patients around the age of 40, while other CVDs were more common in individuals around the age of 60. There were significant differences in sST2 levels between sexes in myocarditis and cardiomyopathy, but not in other CVDs.

Summary: This study measured serum carnitine levels in heart failure patients and found that all 25 carnitines were increased in these patients, with 20 being independently associated with heart failure diagnosis. In non-ischemic dilated cardiomyopathy patients, seven carnitines were identified to independently increase the diagnostic probability. Adding isobutyryl-L-carnitine and stearoyl-L-carnitine to clinical factors improved the accuracy of DCM-HF diagnosis. Certain carnitine levels were found to independently predict the risk of death and rehospitalization in heart failure patients. Therefore, serum carnitines can serve as diagnostic, prognostic, and etiological biomarkers in heart failure.

Summary: The obesity paradox refers to the observation that certain chronic diseases show a protective association between body mass index (BMI) and clinical outcomes. However, this association may be influenced by factors such as limitations of BMI, unintended weight loss due to chronic illness, different phenotypes of obesity, and cardiorespiratory fitness levels. Recent evidence suggests that cardioprotective medications, obesity duration, and smoking status also play a role in the obesity paradox.

Summary: This study introduces methods for gene association and variant interpretation that detect clustering of rare missense variants in Mendelian disease genes, which can enhance disease-gene discovery. The statistical methods presented in this study are more powerful and computationally faster than alternative methods, and can effectively integrate ACMG criteria to provide strong evidence of pathogenicity for variants of uncertain significance.

Summary: The study identified 12 genome-wide significant susceptibility loci for HCM, showing a strong polygenic influence, especially for sarcomere-negative HCM. A genetic risk score influenced the odds of HCM and phenotypic severity in carriers of sarcomere variants. Mendelian randomization identified diastolic blood pressure as a key modifiable risk factor for sarcomere-negative HCM.
