Occurrence and Classification of Cerebrovascular Events after Isolated Bioprosthetic Surgical Aortic Valve Replacement: A Competing Risk Analysis of the CAREAVR Study
<p><b>Background:</b> The long-term incidence of stroke and the proportion of cardioembolic events after bioprosthetic surgical aortic valve replacement (SAVR) remain largely unknown.</p><p><b>Methods:</b> The CAREAVR study ...
Occurrence of Postpericardiotomy Syndrome: Association With Operation Type and Postoperative Mortality After Open-Heart Operations
<h3>Background</h3><p>Postpericardiotomy syndrome (PPS) is a common complication after cardiac surgery. However, large‐scale epidemiological studies about the effect of procedure type on the occurrence of PPS and mortality ...
Atrial Fibrillation Detection via Accelerometer and Gyroscope of a Smartphone
<p>Atrial Fibrillation (AFib), which utilizes the built-in accelerometer and gyroscope sensors (Inertial Measurement Unit, IMU) in the detection. Depending on the patient’s situation,it is possible to use the developed ...
Assessment of myocardial viability with [15O]water PET: A validation study in experimental myocardial infarction
<p>Background: Assessment of myocardial viability is often needed in patients with chest pain and reduced ejection fraction. We evaluated the performance of reduced resting MBF, perfusable tissue fraction (PTF), and ...
Contemporary radiation doses in interventional cardiology: a nationwide study of patient doses in Finland
<p>The amount of interventional procedures such as percutaneous coronary intervention (PCI), transcatheter aortic valve implantation (TAVI), pacemaker implantation (PI) and ablations has increased within the previous decade. ...
Comprehensive Analysis of Cardiogenic Vibrations for Automated Detection of Atrial Fibrillation Using Smartphone Mechanocardiograms
<p>Atrial fibrillation (AFib) is the most common sustained heart arrhythmia and is characterized by irregular and excessively frequent ventricular contractions. Early diagnosis of AFib is a key step in the prevention of ...
Postpericardiotomy syndrome after cardiac surgery
Postpericardiotomy syndrome (PPS) is a well-known complication after cardiac surgery. The syndrome results in prolonged hospital stay, readmissions, and invasive interventions. Previous studies have reported inconsistent ...
Automated Detection of Atrial Fibrillation Based on Time-Frequency Analysis of Seismocardiograms
<p>In this paper, a novel method to detect atrial fibrillation from a seismocardiogram (SCG) is presented. The proposed method is based on linear classification of the spectral entropy and a heart rate variability index ...
