Background: The overall effect of long-term variability in physiological measures on cardiovascular health of older adults and the underlying mechanic pathway remain uncertain.
Methods: We constructed a composite score (0 ~ 3) of variability in physiological measures, including blood pressure, pulse rate, and body mass index, in older adults from the China Health and Retirement Longitudinal Study (CHARLS) 2011 ~ 2015, the Health and Retirement Study (HRS) 2006/2008 ~ 2014/2016, and the UK Biobank 2006 ~ 2019. The associations of the composite score with incident risks of heart disease and stroke were assessed. The mediation roles of several biomarkers were explored.
Results: A higher composite score was related to increased incident risk of heart disease in older adults from the US and the UK and increased incident risk of stroke in all three cohorts. Upon pooling the results, each 1-point increment in the composite score was associated with a 19% (hazard ratio: 1.19; 95% confidence interval: 1.14, 1.30) and a 23% (1.23; 1.12, 1.35) increments in incident risks of heart disease and stroke, respectively. The composite score also exhibited an inverse relationship with grip strength while displaying positive associations with C-reactive protein, glycosylated hemoglobin Alc (HbAlc), and cystatin C. Reduced grip strength, elevated HbAlc, and elevated cystatin C significantly mediated the composite score-associated elevated risks of heart disease and stroke.
Conclusions: Long-term variability in physiological measures was associated with increased incident risks of heart disease and stroke, and the associations were partially mediated through deteriorated biomarkers of muscle strength, hyperglycemia, and kidney function.

Background: The obesity paradox refers to lower mortality rates among overweight or obese individuals within certain populations. However, whether this paradox is applicable to patients undergoing percutaneous coronary intervention (PCI) remains unclear.
Methods: A total of 5,427 patients with coronary artery disease (CAD) who underwent successful PCI between 2005 and 2015 were enrolled.

Background: Atrial fibrillation (AF) increases the risks of stroke and mortality. It remains unclear whether rhythm control reduces the risk of stroke in patients with AF concomitant with hypertrophic cardiomyopathy (HCM).
Methods: We identified AF patients with HCM who were ≥ 18 years old in the Taiwan National Health Insurance Database.

Background: The occurrence of immune-related adverse events (irAEs) seemed to be associated with better outcomes in advanced gastric cancer (AGC) patients. However, research focusing on the impact of the single-organ irAE (uni-irAE) or multi-organ irAEs (multi-irAEs) on the AGC outcome is relatively limited. In this study, we investigated individually the impact of the different irAEs on AGC survival as well as the co-occurrence patterns of multi-irAEs.

Background: Heart failure (HF) is a leading cause of morbidity and mortality worldwide. Various factors can exacerbate disease progression in patients with HF and negatively impact treatment outcomes. This study aims to evaluate the pooled prevalence and contributing factors associated with poor heart failure treatment outcomes in Ethiopia.

Background: An increasing number of patients with congenital heart disease (CHD) engage in physical activities and may exercise at high altitudes (HA). The physiological adaptations required at HA and their implications on individuals with CHD, especially during exercise, remain underexplored. This systematic review aims to investigate cardiopulmonary exercise responses to short-term HA exposure in individuals with CHD.
