Quantitative flow ratio (QFR) is a computation of fractional flow reserve (FFR) based on invasive coronary angiographic images. Calculating QFR is less invasive than measuring FFR and may be associated with lower costs. Current evidence supports the call for an adequately powered randomised comparison of QFR and FFR for the evaluation of intermedia...

Background Coronary physiology-guided PCIs are recommended worldwide. However, invasive coronary physiology methods prolong the procedure, make additional risks for the patients, and prolong the fluoroscopy time for an interventional cardiologist. Otherwise, there is a non-invasive coronary physiology evaluation method QFR, which can be safely used...

Stronger oscillations in the local Earth magnetic field may have an impact on the course of ischemic heart disease. This effect is individual for every person and depends on the sex, age, living territory, season, capability to adjust to magnetic field fluctuations and health status. Individuals who already have cardiovascular disease are more sens...

Introduction: The development of interventional cardiology increases the number of invasive procedures which are inevitably associated with increased exposure to ionizing radiation and associated risks. A percutaneous coronary intervention (PCI) substantiated by evaluation of the coronary artery lesion's functional significance is recommended by b...

Background: Geomagnetic storms strongly affect the human cardiovascular system, misbalancing adaptive mechanisms and causing severe adaptive stress responses at all levels of body regulation. Most physiological changes occur after a defined period following geomagnetic climate alterations, this ‘delay period’ lasts for 2-3 days. Methods: In total,...

Estimation of the agreement between Quantitative Flow Ratio (cQFR), a minimally invasive method to compute FFR value from coronary angiograms in accordance with individual speed of contrast flow within coronary artery (CA), in comparison with FFR, a gold standard method for assessment of functional significance of CA stenosis and assessment of the...

Background: The World Health Organization (WHO) Surgical Safety Checklist has fostered safe practice for 10 years, yet its place in emergency surgery has not been assessed on a global scale. The aim of this study was to evaluate reported checklist use in emergency settings and examine the relationship with perioperative mortality in patients who ha...

Objectives: Atrial fibrillation is the most frequent cardiac arrhythmia affecting over 3 percent and appears to be increasing in general population. In addition to widely discussed such risk factor as obesity, arterial hypertension, electrolytes disbalances and dysfunction of thyroid, there is more and more evidence of human heath interactions with...

Objectives: Acute coronary syndrome as an acute oxygenated blood deprivation to the heart muscle due to atherosclerotic plaque rupture in the coronary artery followed by thrombosis is possibly associated with changes in the Earth’s local time varying magnetic field as they strongly influence hormonal and other regulatory systems’ activity. This stu...

Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort stu...

Introduction: As coronary artery disease is the most frequent cause of cardiac arrest, early invasive strategies may be beneficial for such patients. This study analyses the impact of in-hospital treatment on short-term outcomes of out-of-hospital cardiac arrest (OHCA) survivors. Material and methods: Patients admitted to the Cardiac Intensive C...

Dyspnoea is one of the most frequent symptoms, causing patients (pts) to present to the emergency department (ED). It is a subjective symptom and for this reason, physicians have a difficult task—to assess dyspnoea objectively along with respiratory failure signs (respiratory rate higher than 25 breaths per minute, blood oxygen saturation (SaO2) le...
