Effect of digital tools in outpatient cardiac rehabilitation including home training-results of the EPICURE study.

Introduction: Cardiovascular diseases are the leading cause of death worldwide and are partly caused by modifiable risk factors. Cardiac rehabilitation addresses several of these modifiable risk factors, such as physical inactivity and reduced exercise capacity. However, despite its proven short-term merits, long-term adherence to healthy lifestyle changes is disappointing.

Efficacy of extended, comprehensive outpatient cardiac rehabilitation on cardiovascular risk factors: A nationwide registry.

Aim: Cardiac rehabilitation (CR) is a key component of the treatment of cardiac diseases. The Austrian outpatient CR model is unique, as it provides patients with an extended professionally supervised, multidisciplinary program of 4-6 weeks of phase II (OUT-II) and 6-12 months of phase III (OUT-III) CR. The aim of this analysis was to assess the efficacy of the Austrian outpatient CR model using a nationwide registry.

Pulse waveform characteristics predict cardiovascular events and mortality in patients undergoing coronary angiography.

Objectives: Pulse waveform characteristics (Augmentation Index--AIx and pulse wave transit time) are measures of the timing and extent of arterial wave reflections. Although previous studies reported an independent association with cardiovascular morbidity, it remains to be established that waveform characteristics, derived from noninvasive pulse waveform analysis, predict cardiovascular outcomes independent of and additional to brachial blood pressure.

Methods: We prospectively assessed AIx, heart-rate corrected AIx, and pulse wave transit time, using radial applanation tonometry and a validated transfer function to generate the aortic pressure curve, in 520 male patients undergoing coronary angiography.

Renal function is associated with risk of atrial fibrillation after cardiac surgery.

Background: Atrial fibrillation (AF) frequently occurs after cardiac surgery and is responsible for increased morbidity and resource use. The aim of the present study was to evaluate the association of impaired renal function and the development of postoperative AF.

Methods And Results: Patients undergoing elective cardiac surgery in the absence of significant left ventricular dysfunction (n=253; average age 65+/-11 years) were recruited to the present prospective study.

Ability of neuron-specific enolase to predict survival to hospital discharge after successful cardiopulmonary resuscitation.

Background: Accurate prediction of survival to hospital discharge in patients who achieve return of spontaneous circulation after cardiopulmonary resuscitation (CPR) has significant ethical and socioeconomic implications. We investigated the prognostic performance of serum neuron-specific enolase (NSE), a biochemical marker of ischemic brain injury, after successful CPR.

Methods: In-hospital or out-of-hospital patients with nontraumatic normothermic cardiac arrest who achieved return of spontaneous circulation (ROSC) following at least 5 minutes of CPR were eligible.

Transient left ventricular apical ballooning mimicking acute coronary syndrome in four patients from central Europe.

The syndrome of "apical ballooning" consists of an acute onset of transient extensive akinesia of the apical portion of the left ventricle, without significant stenosis on the coronary angiogram. The syndrome is accompanied by chest symptoms, electocardiographic changes, and limited release of cardiac markers disproportionate to the extent of akinesia. So far, the vast majority of cases with this syndrome have been reported among Japanese population and only a few cases among Caucasian population.

Left ventricular apical ballooning--a novel cardiac disease mimicking acute coronary syndrome: a case report in a Caucasian patient.

The syndrome of "apical ballooning" consists of an acute onset of transient extensive akinesia of the apical portion of the left ventricle, without significant stenosis on the coronary angiogram, accompanied by chest symptoms, ECG changes, and a limited release of cardiac markers disproportionate to the extent of akinesia. So far, the vast majority of cases with this syndrome have been reported from Japanese patients and only a few cases of Caucasian patients have been described. Emotional or physical stress or other preceding triggering factors might play a key role in this cardiomyopathy, but the precise etiology remains unknown.
