: The prevalence of patent foramen ovale (PFO) has been found to be increased in patients with cryptogenic stroke, suggesting an association between these two clinical settings. Insulin resistance is a risk factor for the occurrence of stroke. The triglyceride glucose (TyG) index is a biomarker that reflects the IR status of the body.

Background: A score based on age, creatinine level, and ejection fraction as well as hematocrit value and the presence of emergency surgery (ACEF-II) has been proposed to have predictive value for risk stratification in cardiac surgery. This study aimed to evaluate its utility in patients with non-ST-segment elevation myocardial infarction and unstable angina (NSTEMI-ACS) to predict 1-year major adverse cardiac events (MACE).

Methods: In all, 768 patients with NSTEMI-ACS were enrolled in the study.

Article Synopsis
  • Dual antiplatelet therapy (DAPT) is essential for managing acute and chronic coronary syndromes, helping to lower mortality rates and prevent further complications.
  • A study followed 1500 patients on a specific fixed-dose DAPT (ASA + clopidogrel) to evaluate its effectiveness and safety, primarily focusing on hospitalization and bleeding risks.
  • Results indicated that the fixed-dose combination therapy was effective, with low rates of hospitalization for cardiovascular issues and minimal bleeding complications in appropriately selected patients.

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.

Coronary computed tomography angiography can evaluate coronary arterial plaque composition with high resolution. We aimed to determine and compare the values of systemic immune-inflammation index (SII) and systemic inflammation-response index (SIRI) in different plaque types. Highest values of SIRI and SII were found in mixed plaque type followed by non-calcified plaque type.

Coronary artery disease (CAD) is uncommon in young adult patients. However, these patients have different risk factor profiles and high-risk coronary plaques are more common. The aim of this study was to examine the relations between the coronary plaque burden, plaque composition, serum non-high-density lipoprotein cholesterol (non-HDL-C) levels, and triglyceride/high-density lipoprotein cholesterol (TG/HDL-C) ratio in young adults.

Background: Malnutrition reflects the general condition of a patient including physical condition, protein turnover, and immune competence. Contrast-induced acute kidney injury (CI-AKI) is a disorder that adversely affects the prognosis of older adults. In our study, we aimed to show the relationship between CI-AKI and malnutrition status in elderly patients over 65 years of age with chronic coronary artery disease (CAD).

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.

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.

Introduction: In the current literature, several studies show that PAS (pulmonary artery stiffness) is associated with RV (right ventricular) dysfunction, PAH (pulmonary arterial hypertension), and disease severity in subjects with structural cardiac disease, HIV (human immunodeficiency virus), and chronic lung disease. Hence, our main aim was to use PAS to show the early changes in the pulmonary vascular region in subjects with cirrhosis.

Material And Methods: In this prospective cross-sectional study, 39 subjects who were being followed up with cirrhosis and 41 age- and sex-matched healthy subjects were included in this study.

Objectives: Several studies demonstrate the relationship between coronary artery disease and inflammatory parameters. Nevertheless, there is paucity of data regarding the role of high sensitivity (hs)-C-reactive protein (CRP) to albumin ratio (CAR) in patients with ischemia on gated single photon emission tomography (SPECT) myocardial perfusion imaging (MPI). This study was aimed at demonstrating the relationship between CAR and the occurrence of ischemia on gated SPECT MPI.

Introduction: In this study, we aimed to investigate the usefulness of P wave peak time (PWPT), a novel ECG parameter, in patients who were diagnosed with acute ischaemic stroke (IS) and had paroxysmal atrial fibrillation (PAF) on Holter monitoring.

Materials And Methods: In this retrospective cohort study, we included 90 consecutive patients with acute IS who were admitted to our hospital between January 2017 and July 2019. PWPT was described as the time from the beginning of the P wave to its peak, and it was measured from leads DII and VI.

Tuberculosis-associated pericardial disorders are an excessively rare manifestation of extrapulmonary tuberculosis. The patients may present with constrictive pericarditis or pericardial fluid accumulation leading to cardiac tamponade. This paper reports a case of tuberculosis-associated pericardial effusion with dense fibrinous material not causing tamponade in a foreigner presenting with nonspecific symptoms.

Background: Correlation of increased copeptin levels with various cardiovascular diseases has been described. The clinical use of copeptin levels in patients with hypertrophic cardiomyopathy (HCM) has not been investigated before.

Hypothesis: In this study, we aimed to investigate the prognostic value of copeptin levels in patients with hypertrophic cardiomyopathy (HCM).

Objective: To investigate the possible correlation between serum 25-hydroxyvitamin D levels and resistant hypertension (RH).

Subjects And Methods: Patients who had undergone ambulatory blood pressure measurements (ABPM) during outpatient controls were enrolled. Fifty subjects with RH, 50 with controlled hypertension (CHT) and 50 normotensive subjects (NT) were included in the study.

Objective: In this study, we aimed to investigate the relationship between adult degenerative scoliosis (ADS) and the aortic plaques and diameters.

Method: We included 219 patients with ADS and 100 control patients without ADS. Diameters of ascending, arch, descending and abdominal aorta and number, localization and types of the aortic plaques, and the Cobb angles of all patients were measured from computed tomography (CT) images.

Aim: We investigated the association between platelet indices and the severity of coronary artery disease (CAD) in patients with ST-segment-elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PPCI).

Methods: A total of 484 consecutive patients who were routinely referred to coronary angiography for STEMI and 81 age- and gender-matched patients with normal coronary arteries were included in the present study. We analyzed the relation between the platelet distribution width (PDW) and the angiographic severity of CAD.

Background: Hypertrophic cardiomyopathy (HCM) is a common genetic heart disease characterized by ventricular hypertrophy, myocardial fibrosis, and impaired ventricular relaxation. The exact mechanisms by which fibrosis is caused remain unknown.

Hypothesis: Circulating TGF-β is related to poor prognosis in HCM.
