The role of systemic immune-inflammatory index in predicting contrast-induced nephropathy in non-ST-segment elevation myocardial infarction cases.

Systemic immune-inflammation index (SII) is obtained by multiplying the platelets by the ratio of neutrophils to lymphocytes. We aimed to examine the relationship between contrast induced nephropathy (CIN) development and SII in non-ST-segment elevation myocardial infarction (NSTEMI) patients. 1124 NSTEMI patients included and divided into two groups according to the development of CIN.

Prognostic value of pulmonary artery diameter/aorta diameter ratio in patients with acute pulmonary embolism.

Background: The ratio of pulmonary artery diameter (PAD) to ascending aortic diameter (AoD) has been reported to be a prognostic marker in several lung diseases; however, the usefulness of this tool in patients with acute pulmonary embolism (APE) is unknown. Here, we aimed to determine the long-term prognostic value of the PAD/AoD ratio in patients with APE.

Methods: A total of 275 patients diagnosed with APE at our tertiary care center between November 2016 and February 2022 were included in the study.

Evaluation of Naples prognostic score to predict long-term mortality in patients with pulmonary embolism.

The Naples prognostic score (NPS), which reflects the inflammatory and nutritional status of patients, is often used to determine prognosis in cancer patients. The aim of this study was to determine the long-term prognostic value of the NPS in acute pulmonary embolism (APE) patients. Two hundred thirty-nine patients diagnosed with APE were divided into two groups according to their NPS, and long-term mortality was compared.

Effect of ivabradine on ventricular arrhythmias in heart failure patients with reduced ejection fraction.

Background/introduction: Heart failure patients with reduced ejection fraction are at high risk for ventricular arrhythmias and sudden cardiac death. Ivabradine, a specific inhibitor of the If current in the sinoatrial node, provides heart rate reduction in sinus rhythm and angina control in chronic coronary syndromes.

Objective: The effect of ivabradine on ventricular arrhythmias in heart failure patients with reduced ejection fraction patients has not been fully elucidated.

Left Ventricular Mass Index Predicts Pacemaker-Induced Cardiomyopathy in Patients with Dual Chamber Permanent Pacemakers Implanted Due to Complete Atrioventricular Block.

Background: Pacing-induced cardiomyopathy (PICM) occurs as a result of high-burden right ventricular (RV) pacing, which usually develops in patients with complete atrioventricular (AV) block. There is a paucity of data on the association between PICM and pre-implantation left ventricular mass index (LVMI). Thus, the purpose of this study was to analyze the influence of LVMI on PICM in patients who had dual chamber permanent pacemakers (PPMs) implanted secondary to complete AV block.

Cardiac variables associated with atrial fibrillation occurrence and mortality in octogenarians implanted with dual chamber permanent pacemakers.

Background: There is a dearth of data on the predictors of atrial fibrillation (AF) and the association between AF and long-term mortality in octogenarians with dual-chamber permanent pacemakers (PPM). We investigate the occurrence of AF and whether it is associated with overall mortality among octogenarians with dual-chamber PPM implants.

Methods: Three hundred and fifty-four patients with PPM implants were divided into two groups based on their long-term survival status.

Frontal QRS-T angle may predict reverse dipping pattern in masked hypertensives.

Aims: The frontal QRS-T (fQRST) angle is associated with worse cardiovascular outcome. The study aimed to assess the effect of reverse dipping pattern on f(QRST) angle in newly diagnosed masked hypertensive (MH) patients.

Materials And Methods: Newly diagnosed 244 consecutive MH patients were included.

Prognostic value of serum albumin for long-term mortality in patients with dual-chamber permanent pacemakers.

This investigation aims to examine the prognostic utility of albumin concentrations for long-term all-cause mortality in patients undergoing permanent pacemaker implantation. A total of 1798 patients who received permanent pacemaker implantation were divided into quartiles according to serum albumin concentrations. The significance of albumin in predicting long-term mortality was compared in these quartiles.

Heart rate variability and cardiac autonomic functions in post-COVID period.

Background: The heart rate variability (HRV) is a non-invasive, objective and validated method for the assessment of autonomic nervous system. Although acute manifestations of COVID-19 were widely researched, long-term sequela of COVID-19 are still unknown. This study aimed to analyze autonomic function using HRV indices in the post-COVID period that may have a potential to enlighten symptoms of COVID long-haulers.
