Effect of QRS narrowing after cardiac resynchronization therapy on functional mitral regurgitation in patients with systolic heart failure
(Elsevier Inc., 2016)
The determinants of improvement in functional mitral regurgitation (FMR) after cardiac resynchronization therapy (CRT) remain unclear. We evaluated the predictors of FMR improvement and hypothesized that CRT-induced change ...
The effects of preoperative non-invasive cardiac tests on delay to surgery and subsequent mortality in elderly patients with hip fracture
(IOS Press, 2016)
OBJECTIVE: To investigate the effects of preoperative cardiac tests on the surgical treatment plan and subsequent effects on mortality in elderly patients with hip fracture. METHODS: In this retrospective study, 116 patients ...
Measurement of strain imaging, troponin-i and brain natriuretic peptide levels in radiotherapy-induced cardiac injury
(Akad Doktorlar Yayınevi, 2016)
Radiotherapy (RT) of the thorax can damage the pericardium, myocardium, heart valves, and coronary vessels, with the pericardium being the most frequently damaged. The objectives of this study were to evaluate RT-induced ...
QRS prolongation after cardiac resynchronization therapy is a predictor of persistent mechanical dyssynchrony
(Springer, 2016)
Purpose Prolonged QRS duration is the main selection criterion for cardiac resynchronization therapy (CRT) which ameliorates left ventricular mechanical dyssynchrony (MD). However, consequences of post-CRT QRS prolongation ...
Adjusting the QRS duration by body mass index for prediction of response to cardiac resynchronization therapy: Does one QRS size fit all?
(Wiley, 2016)
Background: QRS duration (QRSd) is known to be affected by body weight and length. We tested the hypothesis that adjusting the QRSd by body mass index (BMI) may provide individualization for patient selection and improve ...
Assessment of energy expenditure, physical activity and sleep pattern in patients with frequent symptomatic ventricular ectopic beats
(Masson Editeur, 2016)
Background. Ventricular ectopic beats (VEBs) are considered as benign ventricular arrhythmias in patients without structural heart disease. However, symptomatic frequent VEBs can adversely affect energy metabolism. The ...
Native electrocardiographic qrs duration after cardiac resynchronization therapy: The impact on clinical outcomes and prognosis
(Churchill Livingstone Inc Medical Publishers, 2016)
Background: We investigated whether reversed electrical remodeling (RER), defined as narrowing of the native electrocardiographic QRS duration after cardiac resynchronization therapy (CRT), might predict prognosis and ...
