Objective: This study investigated the clinical significance of coronary artery tortuosity (CAT) in chronic coronary syndrome (CCS) using Gensini scores.

Method: This retrospective single-center study involved 388 patients undergoing coronary angiography for chest pain, excluding those with acute coronary syndromes or prior coronary interventions. Demographic, clinical, and angiographic data were collected and categorized based on the presence or absence of CAT.

Background: Contrast induced nephropathy (CIN) is one of the feared complications of contrast medium-using procedures. Present study was conducted in order to evaluate the value of systemic inflammatory-response index (SIRI) for development of CIN among patients who underwent primary percutaneous intervention.

Methods: Six hundred seventy-six patients with the diagnosis of ST elevation myocardial infarction were included.

Introduction: Increasing evidence supports the view that pro-inflammatory cytokines play a role in fibrosis after myocardial infarction (MI). It has been suggested that interleukin (IL)-12p40, a pro-inflammatory cytokine, can induce interferon γ (IFN-γ) and matrix metalloproteinase (MMP). However, the role of IL-12p40 in adverse cardiac remodeling (AR) after ST-elevation MI (STEMI) is unclear.

Article Synopsis
  • Matrix metalloproteinases (MMPs) influence the extracellular volume (ECV) in the heart, which can indicate how the left ventricle remodels negatively after a heart attack.
  • The study examined 92 patients who had their first heart attack, looking at changes in matrix volume (MVi) and cell volume (CVi) over six months to see how they correlate with MMP-2 levels.
  • Results showed that higher baseline MVi correlated with adverse remodeling, and changes in MVi were better predictors of this adverse remodeling than changes in ECV, potentially linked to increased inflammation from MMP-2.

Aim    In this study, we aimed to investigate the role of sCD163 / tumor necrosis factor-like weak apoptosis-inducing (TWEAK) ratio in cardiac remodeling in non-elderly patients diagnosed with first acute myocardial infarction (MI).Material and Methods    Forty-four patients (age ranges: 40-64 years) diagnosed with first-time acute ST-elevation MI in the emergency department were evaluated with cardiac magnetic resonance (CMR) imaging. Adverse remodeling (AR) was defined the increases of left ventricular end-diastolic volume by ≥12 % by CMR at 6‑month post-MI TWEAK and sCD163 were measured at the first day (baseline), 2 weeks and 6 weeks post-MI.

Aim    Increasing evidence suggests that autonomic dysfunction may be involved in the etiology of white coat hypertension (WCH). The aim of this study was to evaluate cardiac autonomic function by using heart rate recovery (HRR) indices in patients with WCH classified according to their circadian rhythm type of blood pressure (BP).Material and methods    This cross-sectional study included 120 participants over the age of 18 yrs, including 50 patients diagnosed with WCH and 70 healthy controls with normal in- and out-of-office BP and without any known disease.

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.

Introduction: It is known that the levels of tumor necrosis factor-like weak inducer of apoptosis (TWEAK/TNFSF12) increase after myocardial infarction (MI) and that it interacts with sCD163. It has also been argued that TWEAK can induce matrix metalloproteinases (MMPs) in macrophages.

Aim: To investigate the roles of TWEAK, sCD163, and MMPs in left ventricular (LV) adverse remodeling (AR) in the early post-MI period.

Tissue structure in the infarct and remote zone myocardium post-acute myocardial infarction (MI) may offer prognostic information concerning left ventricular remodeling. We aimed to identify or establish a relationship between adverse remodeling (AR) and changes (Δ) in T1, T2 mapping and extracellular volume (ECV) in post MI periods. Fifty-four MI patients underwent 3 Tesla CMR performed 2 weeks (acute phase) and 6 months post-MI.

Contrast-induced acute kidney injury (CI-AKI) can occur after coronary interventions despite protective measures. We evaluated the effect of urinary system contrast blush grading for predicting post-procedure CI-AKI in 486 patients with chronic coronary artery disease. Patient characteristics and blood samples were collected.

Objective: Increased thickness of epicardial adipose tissue (EAT) and the total coronary artery calcium score (TCACS) are independent predictors of atherosclerosis. The aim of this study was to investigate whether EAT thickness, measured using thoracic computed tomography, and TCACS were greater in patients with sarcoidosis.

Methods: This was a retrospective study.

Background: The relation between body mass index (BMI) and coronary artery disease (CAD) extension remains controversial. A new score was developed to estimate body fat percentage (BFP) known as Relative Fat Mass (RFM) Index. This study aimed to evaluate the value of RFM Index in predicting the severity of the CAD, compared with other anthropometric measurements.

Background And Objectives: Chronic venous insufficiency (CVI) is a common pathology of the circulatory system and is associated with a high morbidity for the patients and causes high costs for the healthcare systems. Arterial stiffness has been shown to be a predictor of cardiovascular events and mortality. The relationship between CVI and arterial stiffness using pulse wave velocity (PWV) and augmentation index (Aix) was evaluated in this study.
