Heart failure with preserved ejection fraction (HFpEF) remains a major public health burden with increasing prevalence but only few effective therapies. Endothelial dysfunction and inflammation are identified as pathophysiological drivers of HFpEF disease progression. MicroRNAs are increasingly recognized as key regulators of these pathological processes, while antimiR-based therapies have been emerged as promising therapeutics in mice and humans.

- The study investigates the relationship between triglyceride levels and the cardiovascular benefits of alirocumab compared to placebo in patients with recent acute coronary syndrome (ACS) who are on statin therapy.
- Results showed that higher baseline triglyceride levels were linked to an increased risk of major adverse cardiovascular events (MACE), whereas alirocumab significantly lowered LDL cholesterol and reduced MACE risk.
- While alirocumab led to a notable decrease in triglycerides, the reduction did not correlate with a lower risk of MACE, suggesting baseline triglyceride levels are more important for cardiovascular risk than reductions achieved through treatment.
Hospitalization of Symptomatic Patients With Heart Failure and Moderate to Severe Functional Mitral Regurgitation Treated With MitraClip: Insights From RESHAPE-HF2.

December 2024
Article Synopsis
- - This study analyzes the effects of mitral transcatheter edge-to-edge repair (M-TEER) on hospitalization rates for patients with functional mitral regurgitation (FMR) and symptomatic heart failure (HF), aiming to clarify conflicting results from previous research.
- - The results indicate that patients who underwent M-TEER experienced significantly lower rates of recurrent heart failure hospitalizations and cardiovascular (CV) deaths over a 24-month period, as well as an improved quality of life compared to those in the control group.
- - Specifically, patients in the M-TEER group spent fewer days in the hospital due to HF or CV issues, with a statistically significant reduction in total days lost due to these health complications.
Article Synopsis
- The study examined the effectiveness of transcatheter mitral-valve repair in patients suffering from heart failure and functional mitral regurgitation, comparing it to standard medical therapy.
- In a trial with 505 patients, results showed that those who received the device had significantly lower rates of hospitalizations for heart failure and cardiovascular death compared to those who only received medical therapy.
- Additionally, patients in the device group experienced a greater improvement in health status, as measured by the Kansas City Cardiomyopathy Questionnaire, indicating better outcomes with the transcatheter procedure.
Clonal hematopoiesis of indeterminate potential (CHIP) is caused by somatic mutations in hematopoietic stem cells and associates with worse prognosis in patients with heart failure. Patients harboring CHIP mutations show enhanced inflammation. However, whether these signatures are derived from the relatively low number of cells harboring mutations or are indicators of systemic pro-inflammatory activation that is associated with CHIP is unclear.
