Atrial fibrillation is often asymptomatic and intermittent making its detection challenging. A photoplethysmography (PPG) provides a promising option for atrial fibrillation detection. However, the shapes of pulse waves vary in atrial fibrillation decreasing pulse and atrial fibrillation detection accuracy. This study evaluated ten robust photoplet...

Background Atrial fibrillation (AF) is the major cause of stroke since approximately 25% of all strokes are of cardioembolic‐origin. The detection and diagnosis of AF are often challenging due to the asymptomatic and intermittent nature of AF. Hypothesis A wearable electrocardiogram (ECG)‐device could increase the likelihood of AF detection. The a...

Comprehensive management of coronary artery disease (CAD) includes physical exercise as a part of daily lifestyle therapy. Still CAD patients generally have low physical activity (PA) and high sedentary behaviour (SB). This review summarizes the effect of exercise training and habitual PA and SB on physical fitness and quality of life (QoL) as well...

Objectives Atrial fibrillation is the most common arrhythmia occurring after cardiac surgery. Less attention has been focused on preoperative atrial fibrillation and anaemia as risk factors for mortality after cardiac surgery. The aim of this study was to determine preoperative risk factors for 30-d mortality after open-heart surgery. Design. The s...
Article
Objectives Postoperative atrial fibrillation (POAF) is the most common arrhythmia after cardiac surgery with an incidence between 15‐50 % and pathophysiology not fully known. By choosing the method of extracorporeal circulation with focus on the reduction of systemic inflammatory response, one can potentially decrease the risk of POAF. In this pros...

Introduction Personalized intervention to increase physical Activity and reduce sedentary behaviour in rehabilitation after Cardiac Operations (PACO) is a smartphone-based and accelerometer-based eHealth intervention to increase physical activity (PA) and reduce sedentary behaviour (SB) among patients recovering from cardiac surgery. Design Prospe...

Objective: Minimal invasive extracorporeal circulation may decrease the need of packed red blood cell transfusions and reduce hemodilution during cardiopulmonary bypass. However, more data are needed on the effects of minimal invasive extracorporeal circulation in more complex cardiac procedures. We compared minimal invasive extracorporeal circula...

Purpose: Cardiac surgery and conventional extracorporeal circulation (CECC) impair the bioavailability of drugs administered by mouth. It is not known whether miniaturized ECC (MECC) or off-pump surgery (OPCAB) affect the bioavailability in similar manner. We evaluated the metoprolol bioavailability in patients undergoing CABG surgery with CECC, M...

Objectives We investigated differences in objectively measured sedentary behaviour (SB) and physical activity (PA) levels in subjects with cardiovascular disease (CVD) diagnosis or high CVD risk compared with healthy controls. Methods The present study includes a subsample (n=1398, Health 2011 Study) of participants, who attended health examinatio...
Article
Objectives: New onset postoperative atrial fibrillation (POAF) after cardiac surgery is associated with increased risk for thromboembolic complications. Compliance with anticoagulation treatment is prerequisite for successful outcome after POAF. We hypothesized that a disciplined anticoagulation protocol initiated instantly after POAF secures a lo...

The time-frequency balanced spectral entropy of the EEG is a monitoring technique measuring the level of hypnosis during general anesthesia. Two components of spectral entropy are calculated: state entropy (SE) and response entropy (RE). Transcatheter aortic valve implantation (TAVI) is a less invasive treatment for patients suffering from symptoma...
Article
The optimal treatment for severe accidental hypothermia is cardiopulmonary bypass because this offers the most rapid rate of rewarming. However, cardiopulmonary bypass therapy is not available in every hospital. In these circumstances, rewarming has to be achieved with other methods. We present a patient who was successfully rewarmed with thoracic...

Atrial fibrillation is a common arrhythmia after cardiac surgery. It increases morbidity, length of hospital stay, and costs of operative treatment. Beta-blockers, sotalol, amiodarone, corticosteroids, and biatrial pacing have been shown to be efficient in the prevention of postoperative atrial fibrillation. The aim of this study was to find out ho...
Article
Introduction: Novel postoperative atrial fibrillation (AF) is a significant problem after cardiac surgery. However, the impact of AF on late morbidity and mortality is unclear. The aim of our study was to assess the predictive value of postoperative AF for the incidence of death, stroke, myocardial infarction (MI) and late AF. Material and methods:...

Background and aims: Atrial fibrillation (AF) is the most common arrhythmia after coronary artery bypass surgery (CABG). Intravenous metoprolol and biatrial pacing have been reported to be effective in AF prophylaxis after cardiac surgery. The purpose of this trial was to compare the efficacy of intravenous metoprolol versus biatrial pacing combin...
Article
Current guidelines recommend β-blockers as the first-line preventive treatment of atrial fibrillation (AF) after cardiac surgery. Despite this, 19% of physicians report using amiodarone as first-line prophylaxis of postoperative AF. Data directly comparing the efficacy of these agents in preventing postoperative AF are lacking. To determine whether...
Article
We conducted a prospective, double-blind, randomized, multicenter study among 241 patients who underwent their first on-pump coronary artery bypass graft (CABG) surgery, aortic valve replacement (AVR), or combined CABG and AVR surgery to determine whether the use of hydrocortisone prevents atrial fibrillation after cardiac surgery. Results showed t...
Article
Atrial fibrillation is the most common arrhythmia occurring after heart surgery. Its prevalence after coronary artery bypass surgery is 17-33%. Atrial fibrillation requires additional treatment, lengthens hospitalization and increases the overall expenses of cardiac surgery. Atrial fibrillation can cause hemodynamic problems, predispose to congesti...

Atrial fibrillation (AF) is the most common arrhythmia to occur after cardiac surgery. An exaggerated inflammatory response has been proposed to be one etiological factor. To test whether intravenous corticosteroid administration after cardiac surgery prevents AF after cardiac surgery. A double-blind, randomized multicenter trial (study enrollment...
Article
Atrial fibrillation (AF) is the most common arrhythmia to occur after cardiac surgery, with an incidence of 20% to 40%. AF is associated with postoperative complications, including increased risk of stroke and need of additional treatment, as well as prolonged hospital stay and increased costs. It has been shown that prophylactic oral administratio...
