Could soluble ST2 levels be used to detect nondipper hypertensive subgroup in newly diagnosed hypertension patients.

Aim: ST2 receptor is a member of toll-like/interleukin-1 receptor family. After the activation of IL-33/ST2 signaling pathway clinically detectable amount of soluble form of ST2 (sST2) is released into the circulation. Previous studies showed that sST2 levels were significantly higher in hypertension patients than in controls.

The association between growth differentiation factor 15 and presence and severity of coronary atherosclerosis.

Purpose: Growth differentiation factor 15 (GDF-15) is a member of the transforming growth factor beta superfamily and is faintly expressed under healthy conditions. GDF-15 is markedly elevated in a variety of diseases, including coronary artery disease (CAD), atrial fibrillation and heart failure. Here, we aimed to investigate the association of GDF-15 with the extent and severity of CAD in patients with stable CAD.

The differences in troponin values among gender in COVID-19 patients.

The aim of this study is to investigate the differences on admission troponin values among gender in hospital outcomes and in the 2-year follow-up period in coronavirus disease (COVID-19) patients. Data of 826 patients with moderate-to-severe COVID-19 disease were analyzed retrospectively. All patients had nasal and oropharyngeal swab samples taken according to Ministry of Health guidelines on admission.

The relationship between Vaspin, Nesfatin-1 plasma levels and presence of fragmented QRS with the severity of coronary atherosclerosis.

Purpose: Despite continuous efforts to address classical risk factors for atherosclerosis, the battle to control the disease is far from over and atherosclerosis is still a major factor in all-cause mortality. To investigate the relations between early diagnosis and severity of coronary atherosclerosis we examined vaspin and nesfatin-1 levels, and the presence of fragmented QRS (fQRS) in admission electrocardiograms.

Materials And Methods: We divided 168 patients into asymptomatic control (18%), <50% coronary artery stenosis (28%), >50% stenosis (31%) and myocardial infarction (MI) (23%) groups.

The impact of daily troponin I and D-dimer serum levels on mortality in COVID-19 pneumonia patients.

Background: Coronavirus disease 2019 (COVID-19) is an infection resulting in very high morbidity and mortality rates globally. Limited data are available on the cardiovascular manifestations in these patients. The aim of this study was to analyse the daily troponin I and D-dimer levels and their impact on the need for intensive care and on mortality rates of COVID-19-infected patients.

De-novo development of fragmented QRS during a six-month follow-up period in patients with COVID-19 disease and its cardiac effects.

Objective: The aim of this study is to examine the probability of de-novo fQRS in patients with mild COVID-19 disease, as an indicator of cardiac injury.

Methods: Data of 256 patients with normal admission electrocardiography and no comorbidities between 1.12.

Significance and usefulness of narrow fragmented QRS complex on 12-lead electrocardiogram in acute ST-segment elevation myocardial infarction for prediction of early mortality and morbidity.

Background: The presence of notched R or S waves without accompanying typical bundle branch blocks, or the existence of an additional wave like RSR' pattern in the original QRS complex (with a duration of <120 ms) has been defined as narrow QRS fragmentation. Persistence of the fQRS found on the admission electrocardiogram (ECG) in patients with acute ST segment elevation myocardial infarction (STEMI) will have prognostic significance in the short term.

Methods: The study was carried out using retrospectively collected data of 296 consecutive patients diagnosed as acute STEMI .

The prognostic significance of narrow fragmented QRS on admission electrocardiogram in patients hospitalized for decompensated systolic heart failure.

Background: Narrow fragmented QRS (fQRS) has recently been recognized as a significant predictor of prognosis in various cardiovascular diseases.

Hypothesis: We hypothesized that the presence of narrow fQRS on admission electrocardiogram (ECG) in patients with decompensated systolic heart failure (HF) of any cause would be associated with long-term prognosis.

Methods: Patients hospitalized for decompensated HF due to ischemic or nonischemic dilated cardiomyopathy (left ventricular ejection fraction <35%) were retrospectively analyzed.
