To clarify the value of self-monitoring of oral anticoagulation, we did a meta-analysis of individual patient data addressing several important gaps in the evidence, including an estimate of the effect on time to death, first major haemorrhage, and thromboembolism. Methods We searched Ovid versions of Embase (1980-2009) and Medline (1966-2009), limiting searches to randomised trials with a maximally sensitive strategy. We approached all authors of included trials and requested individual patient data: primary outcomes were time to death, first major haemorrhage, and first thromboembolic event. We did prespecified subgroup analyses according to age, type of control-group care (anticoagulation-clinic care vs primary care), self-testing alone versus self-management, and sex. We analysed patients with mechanical heart valves or atrial fibrillation separately. We used a random-effect model method to calculate pooled hazard ratios and did tests for interaction and heterogeneity, and calculated a time-specific number needed to treat. Findings Of 1357 abstracts, we included 11 trials with data for 6417 participants and 12 800 person-years of follow-up. We reported a significant reduction in thromboembolic events in the self-monitoring group (hazard ratio 0.51; 95\% CI 0.31-0.85) but not for major haemorrhagic events (0.88, 0.74-1.06) or death (0.82, 0.62-1.09). Participants younger than 55 years showed a striking reduction in thrombotic events (hazard ratio 0.33, 95\% CI 0.17-0.66), as did participants with mechanical heart valve (0.52, 0.35-0.77). Analysis of major outcomes in the very elderly (age >= 85 years, n=99) showed no significant adverse effects of the intervention for all outcomes. Interpretation Our analysis showed that self-monitoring and self-management of oral coagulation is a safe option for suitable patients of all ages. Patients should also be offered the option to self-manage their disease with suitable health-care support as back-up.}, language = {en} } @article{HuberTreszlReibisetal.2013, author = {Huber, Matthias and Treszl, Andras and Reibis, Rona Katharina and Teichmann, Christopher and Zergibel, Irina and Bolbrinker, Juliane and Scholze, Juergen and Wegscheider, Karl and V{\"o}ller, Heinz and Kreutz, Reinhold}, title = {Genetics of melatonin receptor type 2 is associated with left ventricular function in hypertensive patients treated according to guidelines}, series = {European journal of internal medicine : official journal of the European Federation of Internal Medicine}, volume = {24}, journal = {European journal of internal medicine : official journal of the European Federation of Internal Medicine}, number = {7}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0953-6205}, doi = {10.1016/j.ejim.2013.03.015}, pages = {650 -- 655}, year = {2013}, abstract = {Background: Melatonin exerts multiple biological effects with potential impact on human diseases. This is underscored by genetic studies that demonstrated associations between melatonin receptor type 2 gene (MTNR1B) polymorphisms and characteristics of type 2 diabetes. We set out to test the hypothesis whether genetic variants at MTNR1B are also relevant for other disease phenotypes within the cardiovascular continuum. We thus investigated single nucleotide polymorphisms (SNPs) of MTNR1B in relation to blood pressure (BP) and cardiac parameters in hypertensive patients. Methods: Patients (n = 605, mean age 56.2 +/- 9.4 years, 82.3\% male) with arterial hypertension and cardiac ejection fraction (EF) >= 40\% were studied. Cardiac parameters were assessed by echocardiography. Results: The cohort comprised subjects with coronary heart disease (73.1\%) and myocardial infarction (48.1\%) with a mean EF of 63.7 +/- 8.9\%. Analysis of SNPs rs10830962, rs4753426, rs12804291, rs10830963, and rs3781638 revealed two haplotypes 1 and 2 with frequencies of 0.402 and 0.277, respectively. Carriers with haplotype 1 (CTCCC) showed compared to non-carriers a higher mean 24-hour systolic BP (difference BP: 2.4 mm Hg, 95\% confidence interval (CI): 0.3 to 4.5 mm Hg, p = 0.023). Haplotype 2 (GCCGA) was significantly related to EF with an absolute increase of 1.8\% (CI: 0.45 to 3.14\%) in carriers versus non-carriers (p = 0.009). Conclusion: Genetics of MTNR1B point to impact of the melatonin signalling pathway for BP and left ventricular function.

Abstract Objective Patients who suffered from an acute coronary syndrome (ACS) boast a low exercise capacity (EC). To enhance EC is a core component of cardiac rehabilitation (CR). The aim of the study was to investigate predictors of exercise capacity to optimize the rehabilitation process in untrained subgroups. Method: 47286 patients (mean age 6411.62, 74.5\% male) were enclosed in the TROL registry. All patients underwent a bicycle stress test at admission and discharge. The dependent variable for the univariate analysis and multivariate logistic regression was the increase of EC during CR, with a cutoff of 15 Watts (pre/post design). Furthermore comorbidities and physical activity before the index event were analyzed. Results: Exercise capacity enhancement differs between active and inactive patients significantly (21.84 Watt vs. 16.35 Watt; p<0.001). While a male gender (OR 1.62 [95\% CI: 1.51-1.74]) and physical activity before rehabilitation (OR 1.85 [95\% CI: 1.75-1.97]) were positive, comorbidities and age (OR 0.82 [95\% CI: 0.74-0.90]) were negative predictors. Conclusion: In cardiac rehabilitation settings special exercise training programs for elderly and comorbid patients are needed, to enhance their exercise capacity sufficiently.}, language = {en} } @inproceedings{VoellerSalzwedelReibisetal.2014, author = {V{\"o}ller, Heinz and Salzwedel, Annett and Reibis, Rona Katharina and Kaminski, S. and Buhlert, Hermann and Eichler, Sarah and Wegscheider, Karl}, title = {Age and fitness level are strongest limitations of exercise capacity during inpatient cardiac rehabilitation}, series = {European heart journal}, volume = {35}, booktitle = {European heart journal}, publisher = {Oxford Univ.

The aim was to identify relevant parameters in order to objectively assess the in-patient rehabilitation outcome. Methods: From February 2009 to June 2010 1253 patients (70.9 +/- 7.0 years, 78.1\% men) at 12 rehabilitation clinics were enrolled. Items concerning sociodemographic data, the impairment group (surgery, conservative/interventional treatment), cardiovascular risk factors, structural and functional parameters and subjective health were tested in respect of their measurability, sensitivity to change and their propensity to be influenced by rehabilitation. Results: The majority of patients (61.1\%) were referred for rehabilitation after cardiac surgery, 38.9\% after conservative or interventional treatment for an acute coronary syndrome. Functionally relevant comorbidities were seen in 49.2\% (diabetes mellitus, stroke, peripheral artery disease, chronic obstructive lung disease). In three key areas 13 parameters were identified as being sensitive to change and subject to modification by rehabilitation: cardiovascular risk factors (blood pressure, low-density lipoprotein cholesterol, triglycerides), exercise capacity (resting heart rate, maximal exercise capacity, maximal walking distance, heart failure, angina pectoris) and subjective health (IRES-24 (indicators of rehabilitation status): pain, somatic health, psychological well-being and depression as well as anxiety on the Hospital Anxiety and Depression Scale). Conclusion: The outcome of in-patient rehabilitation in elderly patients can be comprehensively assessed by the identification of appropriate key areas, that is, cardiovascular risk factors, exercise capacity and subjective health.

The aim of a cardiac rehabilitation is to improve overall physical health, psychological well-being, physical function, the ability to participate in social life and help patients to change their habits. Regarding the heterogeneity of these aims measuring of the effect of cardiac rehabilitation is still a challenge. This study recommends a concept to assess the effects of cardiac rehabilitation regarding the individual change of relevant quality indicators. Methods: With EVA-Reha; cardiac rehabilitation the Medical Advisory Service of Statutory Health Insurance Funds in Rhineland-Palatinate, Alzey (MDK Rheinland-Pfalz) developed a software to collect data set including sociodemographic and diagnostic data and also the results of specific assessments. The project was funded by the Techniker Krankenkasse, Hamburg, and supported by participating rehabilitation centers. From 01. July 2010 to 30. June 2011 1309 patients (age 71.5 years, 76.1\% men) from 13 rehabilitation centers were consecutively enrolled. 13 quality indicators in 3 scales were developed for evaluation of cardiac rehabilitation: 1) cardiovascular risk factors (blood pressure, LDL cholesterol, triglycerides), 2) exercise capacity (resting heart rate, maximal exercise capacity, maximal walking distance, heart failure [NYHA classification], and angina pectoris [CCS classification]) and 3) subjective health (IRES-24: pain, somatic health, psychological wellbeing and depression as well as anxiety on the HADS). The study was prospective; data of patients were assessed at entry and discharge of rehabilitation. To measure the success of rehabilitation each parameter was graded in severity classes at entry and discharge. For each of the 13 quality indicators changes of severity class were rated in a rating matrix. For indicators without a requirement for medical care neither at entry nor at discharge no rating was performed. Results: The grading into severity classes as well as the minimal important differences were given for the 13 quality indicators. The result of rehabilitation can be demonstrated in suitable form by means of rating of the 13 quality indicators according to a clinical population. The rating model differs well between clinically changed and unchanged patients for the quality indicators. Conclusion: The result of cardiac rehabilitation can be assessed with 13 quality indicators measured at entry and discharge of the rehabilitation program. If a change into a more favorable category at the end of rehabilitation could be achieved it was counted as a success. The 13 quality indicators can be used to assess the individual result as well as the result of a population - e.g. all patients of a clinic in a specific time period.

HypothesisWith respect to the risk factor pattern and treatment effects during a CR stay, there are important differences between STE-ACS and NSTE-ACS patients. MethodsComparison of 7950 patients by STE-ACS or NSTE-ACS status in the Transparency Registry to Objectify Guideline-Oriented Risk Factor Management registry (2010) who underwent an inpatient CR period of about 3 weeks. ResultsSTE-ACS patients compared to NSTE-ACS patients were significantly younger (60.5 vs 64.4 years, P < 0.0001), and had diabetes mellitus, hypertension, or any risk factor (exception: smoking) less often. At discharge, in STE-ACS compared to NSTE-ACS patients, the low-density lipoprotein cholesterol (LDL-C) <100 mg/dL goal was achieved by 75.3\% and 76.2\%, respectively (LDL-C <70 mg/dL by 27.7\% and 27.4\%), the high-density lipoprotein cholesterol goal of >50 mg/dL in women and >40 mg/dL in men was achieved by 49.3\% and 49.0\%, respectively, and the triglycerides goal of <150 mg/dl was achievedby 72.3\% and 74.3\%, respectively (all comparisons not significant).

We investigated the association of HRQoL and body mass index (BMI) as an indicator for obesity. Design: Secondary longitudinal analysis of the ORBITAL study, an intervention study which included high-risk cardiovascular primary care patients with hypercholesterolemia and an indication for statin therapy. Methods: HRQoL was determined with the generic Short Form (SF)-12 health status instrument. Body weight and height were assessed at baseline and at months 6, 12, 18, 24, 30, and 36. We used a linear and a linear mixed-effects regression model to investigate the association between BMI and SF-12 summary scores at baseline as well as between change in BMI and SF-12 summary scores over 3 years. We adjusted for age, sex, smoking status, and in the longitudinal analysis also for the study arm and its interaction term with time. Results: Of the 7640 participants who completed the baseline questionnaire, 6726 participants (mean age: 61 years) were analyzed. The baseline BMI was inversely associated with physical and mental SF-12 summary scores (beta [95\% CI] per 1 kg/ m(2) : -0.36 [-0.41; -0.30] and -0.05 [-0.11; -0.00], respectively). A significant association between the change in BMI and physical SF-12 summary scores over time was only present in women (-0.18 [-0.27; -0.09]) and only in obese participants (-0.19 [-0.29; -0.10]). A change in BMI was directly associated with mental SF-12 summary scores (0.12 [0.06; 0.19]) in the total population. Conclusion: Increases in BMI were associated with decreases in physical HRQoL, particularly in obese individuals and in women. In contrast, the mental HRQoL seemed to increase with increasing BMI over time. Thus, body weight management with respect to the HRQoL should be evaluated differentially by sex and body weight status.}, language = {en} } @unpublished{ReibisGaedeIlligVoeller2014, author = {Reibis, Rona Katharina and Gaede-Illig, Cathleen and V{\"o}ller, Heinz}, title = {Rehabilitation after Acute Myocardial Infarction}, series = {Die Rehabilitation : Zeitschrift f{\"u}r Praxis und Forschung in der Rehabilitation}, volume = {53}, journal = {Die Rehabilitation : Zeitschrift f{\"u}r Praxis und Forschung in der Rehabilitation}, number = {3}, publisher = {Thieme}, address = {Stuttgart}, issn = {0034-3536}, doi = {10.1055/s-0034-1370119}, pages = {191 -- 201}, year = {2014}, language = {de} }
