Long-term hemodynamic responses and reverse remodeling after pharmacotherapy in HFpEF versus HFrEF: a systematic review and meta-analysis.

The acute response to therapeutic afterload reduction differs between heart failure with preserved (HFpEF) versus reduced ejection fraction (HFrEF), with larger left ventricular (LV) stroke work augmentation in HFrEF compared to HFpEF. This may (partially) explain the neutral effect of HFrEF-medication in HFpEF. It is unclear whether such differences in hemodynamic response persist and/or differentially trigger reverse remodeling in case of long-term afterload reduction.

Targeting Soluble TGF-β Factors: Advances in Precision Therapy for Pulmonary Arterial Hypertension.

Pulmonary arterial hypertension (PAH) is a rare progressive disease characterized by pulmonary artery vascular remodeling, increased vascular resistance, and subsequent right ventricular hypertrophy and right heart failure. It is triggered by disrupted transforming growth factor (TGF)-β signaling, including loss-of-function mutations in the bone morphogenetic protein (BMP) receptor 2. Emerging treatments aim to inhibit elevated TGF-β levels or enhance diminished endothelial BMP signaling.

Anti-pyroptosis biomimetic nanoplatform loading puerarin for myocardial infarction repair: From drug discovery to drug delivery.

Pyroptosis is a critical pathological mechanism implicated in myocardial damage following myocardial infarction (MI), and the crosstalk between macrophages and pyroptotic cardiomyocytes presents a formidable challenge for anti-pyroptosis therapies of MI. However, as single-target pyroptosis inhibitors frequently fail to address this crosstalk, the efficacy of anti-pyroptosis treatment post-MI remains inadequate. Therefore, the exploration of more potent anti-pyroptosis approaches is imperative for improving outcomes in MI treatment, particularly in addressing the crosstalk between macrophages and pyroptotic cardiomyocytes.

Association between physical activity and mortality in patients with osteoporosis: a cohort study of NHANES.

Unlabelled: We utilized data from the NHANES to investigate the impact of physical activity on mortality in osteoporotic patients. Our study suggests that osteoporotic patients may require higher volumes of physical activity to reduce mortality risk compared to the general population. In osteoporotic patients, the dose-response relationships between physical activity volumes and both all-cause and cardiovascular mortality were linear.
