AI Article Synopsis

  • Inflammation is crucial in heart changes after a heart attack (MI), and the monocyte to high-density lipoprotein-cholesterol (MHR) ratio is being studied as a marker of this inflammation.
  • A study of 231 patients showed that a higher MHR (greater than 1.6) at hospital admission significantly predicts adverse cardiac remodeling (AR) and increases the risk of mortality, with 23.8% of patients showing AR after 6 months.
  • The findings suggest that measuring MHR upon admission can help identify patients at higher risk for heart failure and death after a heart attack.

Article Abstract

Background: Inflammation plays a critical role in cardiac remodeling after myocardial infarction (MI). Monocyte to high-density lipoprotein-cholesterol (HDL-C) ratio (MHR) has emerged as a potential indicator of inflammation.

Objectives: The study aimed to investigate the prognostic role of MHR at the time of hospital admission in late cardiac remodeling and subsequent 1-year mortality in an academic training and research hospital.

Methods: This prospective multicenter study included 231 patients with acute ST-elevation MI. Left ventricular (LV) functions and volumes were assessed by cardiac magnetic resonance (CMR) imaging at 2 weeks and 6 months post-MI. The definition of adverse cardiac remodeling (AR) was based on the increase of LV end-diastolic volume by ≥ 12% at 6 months post-MI. All patients were followed for survival for 1 year after the second CMR imaging measurements.

Results: At 6 months post-MI, 20 patients (23.8%) exhibited AR. The median MHR was higher in the AR group compared to the group without AR (2.2 vs. 1.5, p < 0.001). A positive correlation was found between MHR and infarct size in the groups with and without AR. High MHR was an independent predictor of AR (OR: 3.21, p = 0.002). The cut-off value of MHR in predicting AR was found to be >1.6 with 92.7% sensitivity and 70.1% specificity (AUC ± SE: 0.839 ± 0.03, p < 0.001). Mortality risk was 5.62-fold higher in the group with MHR of >1.6 (HR: 5.62, p < 0.001).

Conclusions: These results indicate that admission MHR is a useful tool to predict patients with AR who are at risk of progression to heart failure and mortality after MI.

Doxorubicin, a representative drug of the anthracycline class, is widely used in cancer treatment. However, Doxorubicin-induced cardiotoxicity (DIC) presents a significant challenge in its clinical application. Mitochondrial dysfunction plays a central role in DIC, primarily through disrupting mitochondrial dynamics.

Background: Left ventricular (LV) myocardial contraction patterns can be assessed using LV mechanical dispersion (LVMD), a parameter closely associated with electrical activation patterns. Despite its potential clinical significance, limited research has been conducted on LVMD following myocardial infarction (MI). This study aims to evaluate the predictive value of cardiac magnetic resonance (CMR)-derived LVMD for adverse clinical outcomes and to explore its correlation with myocardial scar heterogeneity.

Mitochondria, commonly referred to as "energy factories"of cells, play a crucial role in the function and survival of cardiomyocytes. However, as research on cardiac fibrosis has advanced, mitochondrial dysfunction(including changes in energy metabolism, calcium ion imbalance, increased oxidative stress, and apoptosis)is now recognized as a significant pathophysiological pathway involved in cardiac remodeling and progression, which also negatively affects the function and structure of the heart. In recent years, research focusing on targeting mitochondria has gained significant attention, offering new approaches for treating cardiac fibrosis.

Background: Diastolic wall strain (DWS), also referred to as right ventricular (RV) dysfunction, is a significant predictor of pulmonary embolism (PE) and heart failure (HF). Rooted in linear elastic theory, DWS reflects decreased wall thinning during diastole, indicating reduced left ventricular (LV) compliance and increased diastolic stiffness. Elevated diastolic stiffness is associated with worse outcomes, particularly in PE and HF with preserved ejection fraction (HFpEF).

Robust preclinical models of asymmetric ventricular loading in late gestation reflecting conditions such as hypoplastic left heart syndrome are lacking. We characterized the morphometry and microvascular function of the hypoplastic left ventricle (LV) and remaining right ventricle (RV) in a sham-controlled late gestation fetal lamb model of impaired left ventricular inflow (ILVI). Singleton fetuses were instrumented at ∼120 days gestational age (dGA; term is ∼147 days) with vascular catheters, an aortic flow probe and a deflated left atrial balloon.
