Prognostic Importance of Increased Right Ventricular Afterload in Orthotopic Liver Transplantation Recipients With Endstage Cirrhosis.

BACKGROUND: Severely increased right ventricular (RV) afterload is considered a contra-indication for orthotopic liver transplantation (OLT). This study assesses the effects of mildly increased RV afterload on long-term outcome after OLT in relation to RV function. METHODS: 139 OLT recipients (53±12years, 76% male) were included. Preoperative RV afterload was assessed invasively or, if not available, echocardiographically and categorised as normal, high-normal (mean pulmonary artery pressure [PAP] 20-25mmHg or echocardiographic systolic PAP 35-40mmHg) or mildly elevated (mean PAP 25-35mmHg or systolic PAP 40-50mmHg). The association between level of RV afterload, echocardiographic RV function and postoperative outcome was assessed. RESULTS: Right ventricular afterload was high-normal in 17% and mildly elevated in 12% of patients. Patients with elevated RV afterload had higher echocardiographic RV dimensions and left ventricular filling pressures. RV functional parameters were within normal range and not associated with RV afterload. Increased RV afterload was associated with a higher incidence of postoperative haemodynamic complications (8%, 17%, and 29% for normal, high-normal and mildly elevated RV afterload, respectively, p=0.03) and worse survival (8-year survival 74%, 41% and 37% respectively, p=0.01). Preoperative RV function was not associated with outcome after OLT. CONCLUSIONS: Increased RV afterload was associated with increased haemodynamic complications and worse long-term survival in OLT recipients. Right ventricular function in patients with increased RV afterload was within normal range and not associated with postoperative outcome.

Expectations and perceived barriers to widespread implementation of e­Health in cardiology practice: Results from a national survey in the Netherlands.

INTRODUCTION: Expectations of physicians concerning e­Health and perceived barriers to implementation in clinical practice are scarcely reported in the literature. The purpose of this study was to assess these aspects of cardiovascular e­Health. METHODS: A survey was sent to members of the Netherlands Society of Cardiology. In total, the questionnaire contained 30 questions about five topics: personal use of smartphones, digital communication between respondents and patients, current e­Health implementation in clinical practice, expectations about e­Health and perceived barriers for e­Health implementation. Age, personal use of smartphones and professional environment were noted as baseline characteristics. RESULTS: In total, 255 respondents filled out the questionnaire (response rate 25%); 89.4% of respondents indicated that they considered e­Health to be clinically beneficial, improving patient satisfaction (90.2%), but also that it will increase the workload (83.9%). Age was a negative predictor and personal use of smartphones was a positive predictor of having high expectations. Lack of reimbursement was identified by 66.7% of respondents as a barrier to e­Health implementation, as well as a lack of reliable devices (52.9%) and a lack of data integration with electronic medical records (EMRs) (69.4%). CONCLUSION: Cardiologists are in general positive about the possibilities of e­Health implementation in routine clinical care; however, they identify deficient data integration into the EMR, reimbursement issues and lack of reliable devices as major barriers. Age and personal use of smartphones are predictors of expectations of e­Health, but the professional working environment is not.

Short-term career perspectives of young cardiologists in the Netherlands.

BACKGROUND: Since it was anticipated that the need for doctors would increase due to demographic changes, the number of positions for medical specialty training programs has increased from the year 2000 onwards. However, the number of permanent positions for young cardiologists did not follow that trend leading to concerns about future employment. Therefore, the aim of the current study was to assess short-term career perspectives of young cardiologists in the Netherlands. METHODS: All cardiologists who ended their training between 1 January 2011 and 31 December 2014 were invited to fill in a questionnaire about their first employment status and were followed yearly until the participant had a permanent position. The timespan between the end of training and the moment of permanent employment was assessed. Furthermore, the association between professional profile and short-term career perspectives was investigated. RESULTS: The observed unemployment was 1.6% and lasted less than a year in all cases. Of the participants, 77% started their career with a temporary contract; within four years this was 7%. Of young cardiologists, 46% started their career as a fellow and 24% as an attending physician. A total of 29% of male cardiologists started their career with a permanent contract as compared with 12% of females (p = 0.01). Within two years this difference was no longer observed. CONCLUSIONS: Unemployment is low among young cardiologists. Most cardiologists start their career with a temporary contract. The time to a permanent contract is slightly longer for female cardiologists as compared with males.

Electrocardiographic detection of pulmonary hypertension in patients with systemic sclerosis using the ventricular gradient.

BACKGROUND: Pulmonary hypertension (PH) is a leading cause of death in systemic sclerosis (SSc) patients. The current study assessed the ability of the ECG-derived ventricular gradient (VG-RVPO) to detect PH and predict all-cause mortality in PH patients with subtypes of SSc differing in the extent of multi-organ involvement. METHODS: ECGs were obtained from 196 patients with limited and 77 patients with diffuse SSc included from our screening programme on cardiac complications. The association of the VG-RVPO with (1) the presence of PH, (2) conventional screening parameters and (3) survival in PH patients was assessed. RESULTS: In limited SSc patients an elevated VG-RVPO corresponded with the presence of PH (-5±12 mV.ms vs -22±16 mV.ms, P<0.01), correlated significantly with conventional screening parameters and had a better diagnostic performance than the presence of a right heart axis (AUC 0.81 vs 0.60; P=0.04). These differences were not observed in patients with diffuse SSc. An elevated VG-RVPO was associated with decreased survival in all SSc patients with PH (3 year survival 30% vs 64%, P=0.02). CONCLUSION: An elevated VG-RVPO is associated with PH in limited SSc patients and with decreased survival in all SSc patients with PH.

Randomized comparison of a multidisciplinary team care program with usual care in patients with systemic sclerosis.

OBJECTIVE: To compare the effectiveness of a multidisciplinary team care program with usual outpatient care in patients with systemic sclerosis (SSc; scleroderma). METHODS: We performed a randomized controlled trial comparing a 12-week multidisciplinary team care program (1 day per week; individual treatments, group exercises, and group education) with outpatient clinic care. Outcome measures included the Hand Mobility in Scleroderma (HAMIS) test, grip strength, maximal mouth opening (MMO), 6-minute walk distance (6MWD), maximum aerobic capacity (VO(2max) ), Checklist Individual Strength 20 (CIS-20), SSc Health Assessment Questionnaire (HAQ), and Short Form 36 (SF-36), assessed at 0, 12, and 24 weeks. Statistical comparisons of change scores were done by analysis of covariance. RESULTS: Twenty-eight patients were assigned to the intervention group (mean age 53.9 years, 15 of 28 with diffuse SSc) and 25 were assigned to the control group (mean age 51.7 years, 15 of 25 with diffuse SSc). Twenty-five patients (89%) in the intervention group completed the treatment program. At 12 weeks, there was a significantly greater improvement in grip strength (2.2 versus -1.8 kg; P = 0.001), MMO (1.4 versus -0.9 mm; P = 0.011), 6MWD (42.8 versus 3.9 meters; P = 0.021), and HAQ score (-0.18 versus 0.13; P = 0.025) in the intervention group, whereas differences for the other outcome measures did not reach significance. At 24 weeks, the effect on grip strength persisted. CONCLUSION: In patients with SSc, a 12-week multidisciplinary day patient treatment program was more effective than regular outpatient care with respect to 6MWD, grip strength, MMO, and HAQ score, but not for VO(2max) , HAMIS test, CIS-20, SF-36, and visual analog scale for pain. This study provides a first step in quantifying the effect of a multidisciplinary team care program and warrants the conduct of further intervention studies.

Pulmonary hypertension: the role of the electrocardiogram.

A 54-year-old female was referred to our centre for further evaluation of recently established severe pulmonary hypertension. Six months prior to presentation to the cardiologist of the referring centre, the patient had first experienced exertional dyspnoea. At the time of presentation to the referring cardiologist, the patient's ECG showed signs of an increased right heart load. Interestingly, this patient had undergone a thorough cardiac evaluation in the referring centre seven years before when she presented with severe hyperthyroidism. At that time there were no symptoms or signs of pulmonary hypertension on ECG, echocardiography, or at heart catheterisation. Thorough evaluation in cooperation with the referring centre demonstrated that this patient was suffering from idiopathic pulmonary arterial hypertension, a rare form of pulmonary hypertension. We conclude this report with a discussion on the potential use of the ECG for the diagnosis of increased right heart load. (Neth Heart J 2008;16:250-4.).
