Cardiac rehabilitation for heart failure: Do older people want to attend and are they referred?

Purpose Uptake of cardiac rehabilitation services by older people is suboptimal. Offering suitable services may increase participation. This study investigated older heart failure patients' preferences between hospital, community and home-based service models and sociodemographic and clinical factors associated with these preferences. Rates of referral were examined. Methods Cross-sectional survey of patients aged 65 years and older consecutively admitted to elderly care, cardiology and general medicine wards in a large UK hospital with confirmed heart failure between March-December 2009. A 57-item interview schedule incorporating open and closed questions and standard measures was developed enabling both quantitative and qualitative analysis. Associations between patients' preferences and characteristics including disease severity (New York Heart Association [NYHA] classification) and comorbidity (Charlson comorbidity score) were analysed using Chi-squared tests and one-way ANOVA. Results One hundred and six interviews were completed (mean age 77.8 ± 7.3, 62% male, 47% lived alone). Most patients had moderate-severe heart failure (55% NYHA class III; 34% class II) and co-morbidities (mean Charlson score 3.3 ± 1.7). Most opted for cardiac rehabilitation (72%), preferring hospital to community classes. Those preferring hospital programmes were younger (mean 5.1 years, 95% CI -10.1 to -0.1, P = 0.043) than those preferring not to participate. Neither disease severity nor comorbidity was associated with preferences. Only 21% were referred to any cardiac rehabilitation service. Conclusion Most of these older heart failure patients wanted to attend cardiac rehabilitation, but few were referred. Age was related to preferring certain cardiac rehabilitation service models but not to an overall preference to attend. Referral processes need urgent improvement and offering choice of service models may increase participation. © 2014 Elsevier Masson SAS and European Union Geriatric Medicine Society

Stress doppler echocardiography in systemic sclerosis : evidence for a role in the prediction of pulmonary hypertension

OBJECTIVE: Patients with systemic sclerosis (SSc) in whom pulmonary hypertension (PH) is not suspected have been reported to develop an inappropriate increase of pulmonary artery systolic pressure as estimated by Doppler echocardiography under conditions of exercise (pulmonary artery systolic pressure under exercise). We undertook this study to investigate whether this increase or any other parameter detectable by stress Doppler echocardiography has utility in predicting the development of PH in SSc. METHODS: We enrolled a total of 170 patients with SSc previously investigated using standard and stress Doppler echocardiography and tissue Doppler imaging. Each patient was evaluated at baseline and yearly for skin and internal organ involvement. Right-sided heart catheterization was carried out when PH was suspected. The baseline Cochin Risk Prediction Score was calculated retrospectively. RESULTS: During followup, 6 patients (3.5%) developed PH. Compared with patients without any feature suggesting PH, the Cochin Risk Prediction Score was higher in this group (mean \ub1 SD 4.2 \ub1 0.9 versus 3.4 \ub1 0.9; P < 0.05), as was the difference between pulmonary artery systolic pressure under exercise and pulmonary artery systolic pressure (\u394pulmonary artery systolic pressure) (18.2 \ub1 7 mm Hg versus 9.4 \ub1 6.5 mm Hg; P < 0.001), even when adjusted for cardiac index changes. In multivariate analysis, \u394pulmonary artery systolic pressure (hazard ratio [HR] 3.4 [95% confidence interval 1.4-8], P < 0.01) and Cochin Risk Prediction Score within the fifth quintile of the values registered in our series (HR 9.3 [95% confidence interval 1.4-63.7], P < 0.05) were the only factors independently predictive of PH during followup. A \u394pulmonary artery systolic pressure cutoff of >18 mm Hg, identified by receiver operating characteristic curve analysis, had a sensitivity of 50% and a specificity of 90% for the development of PH during followup. CONCLUSION: An inappropriate response to exercise among patients with SSC is detectable by stress Doppler echocardiography. Independently of other clinical associations, increased \u394pulmonary artery systolic pressure heralds PH. Stress Doppler echocardiography may represent an additional screening tool for this severe complication

Standardizing clinical care measures of rheumatic heart disease in pregnancy: A qualitative synthesis

© 2019 Wiley Periodicals, Inc. Background: Rheumatic heart disease (RHD) is a preventable cardiac condition that escalates risk in pregnancy. Models of care informed by evidence-based clinical guidelines are essential to optimal health outcomes. There are no published reviews that systematically explore approaches to care provision for pregnant women with RHD and examine reported measures. The review objective was to improve understanding of how attributes of care for these women are reported and how they align with guidelines. Methods: A search of 13 databases was supported by hand-searching. Papers that met inclusion criteria were appraised using CASP/JBI checklists. A content analysis of extracted data from the findings sections of included papers was undertaken, informed by attributes of quality care identified previously from existing guidelines. Results: The 43 included studies were predominantly conducted in tertiary care centers of low-income and middle-income countries. Cardiac guidelines were referred to in 25 of 43 studies. Poorer outcomes were associated with higher risk scores (detailed in 36 of 41 quantitative studies). Indicators associated with increased risk include anticoagulation during pregnancy (28 of 41 reported) and late booking (gestation documented in 15 of 41 studies). Limited access to cardiac interventions was discussed (19 of 43) in the context of poorer outcomes. Conversely, early assessment and access to regular multidisciplinary care were emphasized in promoting optimal outcomes for women and their babies. Conclusions: Despite often complex care requirements in challenging environments, pregnancy provides an opportunity to strengthen health system responses and address whole-of-life health for women with RHD. A standard set of core indicators is proposed to more accurately benchmark care pathways, outcomes, and burden

Clinical Evaluation of Targeted Arterial Infusion of Verapamil in the Interventional Chemotherapy of Primary Hepatocellular Carcinoma

This study evaluates the clinical effectiveness of targeted arterial infusion of verapamil in interventional treatment of primary hepatocellular carcinoma. For this purpose, in 273 patients with middle- or late-stage primary hepatocellular carcinoma, verapamil, IL-2, and chemotherapeutic agents were infused into the target tumor vasculature through femoral artery using Seldinger technique. The medications were infused as serial dilutions, and effectiveness was evaluated after two treatment cycles. Among these 273 patients, 76 cases showed clinical cure or significant improvement, 119 cases improved, 64 cases stabilized, while 14 cases progressed or deteriorated. In 238 patients, KPS score and body weights were stabilized. Regarding side effects, 99 patients (36.3%) developed leukopenia; 160 patients had gastrointestinal reactions (58.6%); 80 patients (29.3%) presented with elevated ALT/AST profile; and 65 cases (23.8%) had pyrexia; however, these side effects abated quickly. No elevations in BUN/Cr and/or allergic reactions were observed. Pre- and post-intervention cardiac function did not change in all the patients. No significant change was observed in ECG. Liver function was also improved after two cycles of treatment. It was concluded that verapamil management via targeted arterial infusion could effectively reverse the multidrug resistance in cancer cells in primary hepatocellular carcinoma patients and therefore enhanced the efficacy of chemotherapy

A grounded theory study: Exploring health care professionals decision making when managing end stage heart failure care

Aim: To explore how healthcare professionals in an acute medical setting make decisions when managing the care of patients diagnosed with end stage heart failure, and how these decisions impact directly on the patient's end of life experience. Design: A constructivist grounded theory approach was adopted. Method: A purposive sample was used to recruit participants that included 16 registered nurses, 15 doctors and 16 patients. Data were collected using semi-structured interviews and focus groups over a 12-month period of fieldwork concluding in 2017. The interviews were recorded and transcribed and the data were analysed using constant comparison and QSR NVivo. Findings: Four theoretical categories emerged from the data to explain how healthcare professionals and patients negotiated the process of decision making when considering end of life care. These were: signposting symptoms, organizing care, being informed and recognizing dying. The themes revolved around a core category ‘a vicious cycle of heart failure care’. Conclusion: Healthcare professionals need to engage in informed decision making with patients to break this ‘vicious cycle of care’ by identifying key stages in the terminal phase of heart failure and correctly signposting the patient to the most suitable healthcare care professional for intervention. Impact: This study provides a theoretical framework to explain a ‘vicious cycle of care’ for patients diagnosed with end stage heart failure. This theory grounded in data demonstrates the need for both acute and primary care to design an integrative end of life care pathway for heart failure patients which addresses the need for early shared decision making between the healthcare professional, family and the patient when it comes to end of life conversations

Aortic stiffness as a marker of cardiac function and myocardial strain in patients undergoing aortic valve replacement

Background: Cardiac function and myocardial strain are affected by cardiac afterload, which is in part due to the stiffness of the aortic wall. In this study, we hypothesize that aortic pulse wave velocity (PWV) as a marker of aortic stiffness correlates with conventional clinical and biochemical markers of cardiac function and perioperative myocardial strain in aortic valve replacement (AVR). Methods: Patients undergoing AVR for aortic stenosis between June 2010 and August 2012 were recruited for inclusion in this study. PWV, NYHA class and left ventricular (LV) function were assessed pre-operatively. PWV was analysed both as a continuous and dichotomous variable according to age-standardized reference values. B-type natriuretic peptide (BNP) was measured pre-operatively, and at 3 h and 18-24 h after cardiopulmonary bypass (CPB). NYHA class, leg edema, and LV function were recorded at follow-up (409 ± 159 days). Results: Fifty-six patients (16 females) with a mean age of 71 ± 8.4 years were included, with 50 (89%) patients completing follow-up. The NYHA class of PWV-norm patients was significantly lower than PWV-high patients both pre- and post-operatively. Multiple logistic regression also highlighted PWV-cut off as an independent predictor of NYHA class pre- and post-operatively (OR 8.3, 95%CI [2.27,33.33] and OR 14.44, 95%CI [1.49,139.31] respectively). No significant relationship was observed between PWV and either LV function or plasma BNP. Conclusion: In patients undergoing AVR for aortic stenosis, PWV is independently related to pre- and post-operative NYHA class but not to LV function or BNP. These findings provisionally support the use of perioperative PWV as a non-invasive marker of clinical functional status, which when used in conjunction with biomarkers of myocardial strain such as BNP, may provide a holistic functional assessment of patients undergoing aortic valve surgery. However, in order for PWV assessment to be translated into clinical practice and utilised as more than simply a research tool, further validation is required in the form of larger prospective studies specifically designed to assess the relationship between PWV and these functional clinical outcomes

IVC CLAMP: infrahepatic inferior vena cava clamping during hepatectomy - a randomised controlled trial in an interdisciplinary setting

<p>Abstract</p> <p>Background</p> <p>Intraoperative haemorrhage is a known predictor for perioperative outcome of patients undergoing hepatic resection. While anaesthesiological lowering of central venous pressure (CVP) by fluid restriction is known to reduce bleeding during transection of the hepatic parenchyma its potential side effects remain poorly investigated. In theory it may have negative effects on kidney function and tissue perfusion and bears the risk to result in severe haemodynamic instability in case of profound intraoperative blood loss. The present randomised controlled trial evaluates efficacy and safety of infrahepatic inferior vena cava (IVC) clamping as an alternative surgical technique to reduce CVP during hepatic resection.</p> <p>Methods/Design</p> <p>The proposed IVC CLAMP trial is a single-centre randomised controlled trial with a two-group parallel design. Patients and outcome-assessors are blinded for the treatment intervention. Patients undergoing elective hepatic resection due to any reason are enrolled in IVC CLAMP. All patients admitted to the Department of General-, Visceral-, and Transplant Surgery, University of Heidelberg for elective hepatic resection are consecutively screened for eligibility and written informed consent is obtained on the day before surgery. The primary objective of this trial is to assess and compare the amount of blood loss during hepatic resection in patients receiving surgical CVP reduction by clamping of the IVC as compared to anaesthesiological CVP without infrahepatic IVC clamping reduction. In addition to blood loss a set of general as well as surgical variables are analysed.</p> <p>Discussion</p> <p>This is a randomised controlled patient and observer blinded two-group parallel trial designed to assess efficacy and safety of infrahepatic IVC clamping during elective hepatectomy.</p> <p>Trial registration</p> <p>ClinicalTrials NCT00732979</p
