Article Synopsis
  • * It found that patients with AF had significantly higher FIB-4I scores compared to those in sinus rhythm, indicating a potential connection between liver health and AF risk.
  • * Low FIB-4I levels (≤1.29) were identified as a strong indicator for the absence of AF, suggesting that monitoring liver fibrosis could help assess the likelihood of AF in individuals undergoing heart evaluations.

Background: Because patients often already have coronary artery disease (CAD) at the time of a coronary artery computed tomography angiography (CCTA) examination, we examined the medications prescribed by medical doctors for lifestyle-related diseases and investigated what possible role pharmacists can play in prescribing.

Methods: Patients (n = 1357) who underwent CCTA examination were divided into two groups according to the presence or absence of lifestyle-related diseases [hypertension (HTN), dyslipidemia (DL) and diabetes mellitus (DM)], and the relationship between the presence or absence of CAD was examined.

Results: The rate of CAD was significantly higher in patients with HTN, DL or DM than in patients without these diseases.

Coronary artery stenosis is often advanced by the time coronary computed tomography angiography (CCTA). Statins are the most important anti-lipidemic medication for improving the prognosis of coronary artery disease (CAD) patients. Although lipid-lowering therapy using statins appears to have been established as a method for preventing CAD, there remains the problem that CAD cannot be completely suppressed.

The utility of telomere G-tail length to predict coronary artery disease (CAD) remains controversial. CAD results from coronary artery narrowing due to cholesterol and lipid accumulation, augmented by inflammatory cells and other factors. This study explored the significance of telomere G-tail length in suspected CAD patients.

Background: Chronic limb-threatening ischemia (CLTI) is the most advanced stage of peripheral artery disease. Therefore, a multidisciplinary approach is necessary to avoid major amputation in CLTI patients. Malnutrition worsens the condition of CLTI patients, and therefore, it may be important to evaluate the nutritional status in patients with CLTI.

  • A study analyzed the levels of apoE-rich HDL in 113 patients to assess the links between metabolic syndrome (MetS) and HDL cholesterol levels.
  • The results showed that participants with MetS had lower apoE-rich HDL cholesterol and a lower ratio of apoE-HDL to total HDL compared to those without MetS.
  • Additionally, lower levels of apoE-HDL were associated with higher visceral fat and plasma triglycerides, indicating that apoE-rich HDL might be a helpful marker for understanding MetS and related cardiovascular issues.
