The Predictive Effect of Negative Psychological Emotions of Anxiety and Depression on the Poor Prognosis of CHD Patients with Stent Implantation and the Improvement of Clinical Intervention Measures.

OBJECTIVE: To explore the predictive effect of negative emotions such as anxiety and depression on the poor prognosis of coronary heart disease (CHD) patients with stent implantation and to seek the improvement of clinical intervention measures. METHODS: A total of 303 patients with CHD and PCI were recruited from February 2019 to April 2021. The risk factors of CHD such as anxiety and depression, age, sex, smoking and drinking, BMI, hypertension, diabetes, dyslipidemia, and family history of CHD were collected. Meanwhile, clinical data such as laboratory examination, angiography, diseased vessels, and stent types were collected. The patients were followed up for 1 year, and the medical records, hospitalization records, or death records were checked by telephone interview once a month. Major adverse cardiovascular events (MACE) such as emergency and causes, readmission times and causes, new nonfatal myocardial infarction, stent restenosis, heart failure, arrhythmia, and death were recorded. The incidence of anxiety and depression in patients after PCI was counted, and Cox regression was applied to analyze the influence and prediction of anxiety and depression on MACE in patients with CHD stent implantation and improve clinical intervention measures. RESULTS: Compared with those without MACE, anxiety (56.25% vs 30.63%), depression (62.5% vs 22.88%, P < 0.01), anxiety combined with depression (46.88% vs 15.50%, P < 0.01), and hypertension history (71.8% vs 39.11%, P < 0.01) were more common in patients with MACE. Uncorrected Cox proportional hazard regression found that people with anxiety had a higher risk of developing MACE than those without anxiety (HR 3.181, P < 0.01). Multiple Cox proportional hazard regression analysis of anxiety showed that anxiety was an independent predictor of cumulative MACE (P < 0.01). The risk of developing MACE in patients with anxiety was 3.742 times higher than that in patients without anxiety (P < 0.01). Uncorrected Cox hazard regression analysis showed that people with depression had a higher risk of developing MACE than those without depression (HR 5.434, P < 0.01). Furthermore, the results also uncovered that depression was an independent predictor of cumulative MACE (P < 0.01). The risk of MACE in patients with depression was 3.087 times higher than that in patients without depression (P < 0.01). Cox hazard regression showed that the risk of MACE in patients with anxiety and depression was significantly higher than that in patients without anxiety and depression (HR 4.642, P < 0.01). After screening, it was found that anxiety with depression could predict the occurrence of MACE (P < 0.01). The risk of MACE in patients with anxiety and depression was 3.702 times higher than that in patients without anxiety and depression (P < 0.01). Cox regression analysis showed that the risk of MACE with only anxiety and depression was 2.793 times higher than that without anxiety and depression (95% CI 0.914 8.526), with no statistical significance (P > 0.05), and the risk of MACE with depression without anxiety was significantly higher than that without anxiety and depression (P < 0.01). The risk of MACE in patients with anxiety and depression was 7.303 times higher than that in patients without anxiety and depression (P < 0.01). CONCLUSION: Negative emotions such as anxiety and depression can increase the risk of poor prognosis of patients with CHD. Therefore, in clinical work, in addition to routine treatment and nursing during hospitalization, it is recommended to screen patients with depression in CHD patients. Medical staff should use simple and effective assessment tools in time and take active measures to improve the depression of patients. This trial is registered with ChiCTR2200055645.

Living with ureteric stents: a phenomenological study.

BACKGROUND: patients with ureteric stents (JJ stents) have reported symptoms such as voiding dysfunction, incontinence, depression and sexual dysfunction, which have impacted on their quality of life, since the procedure was first described by Zimskind in 1967. AIM: the aim of this study was to enhance understanding of the lived experience of having a ureteric stent. METHOD: the research design used was hermeneutic interpretive phenomenology, underpinned by Heidegger's interpretive phenomenology. FINDINGS: this phenomenological study found that ureteric stents have an impact on patients' quality of life. The five themes that emerged were: disruption to activities of daily life, burden on my physical body, burden on my mind, influence of time and influence of others. CONCLUSION: urological nurses can enhance the patient's experience of living with a ureteric stent by educating patients regarding stent symptoms and management, giving psychological support and advocating for the patient with adverse stent-related symptoms.

Examination of Physicians' Perception of the Indications of Colorectal Stents in the Management of Malignant Large Bowel Obstruction: A Provincial Survey.

Introduction. Data are conflicting when assessing indications for colorectal self-expandable metallic stents (SEMS) in managing acute malignant large bowel obstruction (MLO). In November 2014, European and American Societies published guidelines to aid in understanding which patients might benefit from colorectal stenting. Yet, there remain marked disparities in clinical practice. Methods. A web-based survey was sent to Gastroenterologists and Surgical Specialists across Quebec to assess physicians' knowledge and adherence to the indications for colonic SEMS placement in the management of MLO using eight clinical scenarios. Results. Out of 112 respondents, 74% preferred surgical intervention in young, healthy individuals with MLO. Advanced age and comorbidities motivated 56.3% (95% CI 47.1-65.5%) of participants to opt for SEMS placement. In palliative settings of patients undergoing chemotherapy including bevacizumab, a minority of respondents followed guidelines, 12.5% (95% CI 6.4-18.6%) for young patients and 25.0% for elderly patients (95% CI 17.0-33.0%). The pooled overall adherence to guidelines was 50.4% (95% CI 40.7-59.3%). Conclusion. This survey suggests that guidelines recommendations are not being implemented by at least half of specialists involved in the care of patients with MLO. Future studies should attempt to identify possible barriers responsible for this impaired knowledge translation and tailored educational initiatives planned accordingly.

Effect of mobile phone reminder messages on adherence of stent removal or exchange in patients with benign pancreaticobiliary diseases: a prospectively randomized, controlled study.

BACKGROUND: Plastic and covered metal stents need to be removed or exchanged within appropriate time in case of undesirable complications. However, it is not uncommon that patients do not follow the recommendation for further stent management after Endoscopic Retrograde Cholangiopancreatography (ERCP). The effect of short message service (SMS) intervention monthly on the stent removal/exchange adherence in patients after ERCP is unknown at this time. METHODS: A prospective, randomized controlled study was conducted. After receiving regular instructions, patients were randomly assigned to receive SMS reminding monthly (SMS group) for stent removal/exchange or not (control group). The primary outcome was stent removal/exchange adherence within appropriate time (4 months for plastic stent or 7 months for covered stent). Multivariate analysis was performed to assess factors associated with stent removal/exchange adherence within appropriate time. Intention-to-treat analysis was used. RESULTS: A total of 48 patients were randomized, 23 to the SMS group and 25 to the control. Adherence to stent removal/exchange was reported in 78.2 % (18/23) of patients receiving the SMS intervention compared with 40 % (10/25) in the control group (RR 1.98, 95 % CI 1.16-3.31; p = 0 · 010). Among patients with plastic stent insertion, the median interval time from stent implantation to stent removal/exchange were 90 days in the SMS group and 136 days in the control respectively (HR 0.36, 95 % CI 0.16-0.84, p = 0.018). No difference was found between the two groups regarding late-stage stent-related complications. The rate of recurrent abdominal pain tended to be lower in SMS group without significant difference (8.7 vs 28 %, p = 0.144). Multivariate logistic regression analyses revealed that SMS reminding was the only factor associated with adherence of stent removal/exchange (OR 6.73, 95 % CI 1.64-27.54, p = 0.008). CONCLUSION: This first effectiveness trial demonstrated that SMS reminding monthly could significantly increase the patient adherence to stent removal/exchange after ERCP. TRIAL REGISTRATION: The study was respectively registered on July 10 in 2016 at ClinicalTrials.gov ( NCT02831127 ).

[Informed consent for aortic pathology].

Obtaining informed consent from patients and their families before surgery, particularly for aortic pathology, is a necessary, and very important, step. This is because, although the risk of death from asymptomatic disease is underestimated in many cases, surgery for aortic pathology is generally associated with higher risks of mortality and morbidity than that in other fields. The importance of informed consent is the same in principle even in emergency cases. The surgeon must faithfully provide accurate medical information to the patient and family members, including a summary of the patient's condition, the purposes and necessity of treatment, alternatives, details of the procedure, risks, and possible postoperative complications. Extra consideration should be given to offering explanations at a level appropriate for the individual patient, according to factors such as age-group, philosophy, and comprehension ability, to ensure that patients fully understand and are in a position to make a decision of their own volition. The process of giving information and obtaining informed consent offers a prime opportunity to build a strong surgeon-patient relationship.

[Perceived health status and pharmacological adherence of patients who underwent percutaneous coronary intervention]. / Estado de saúde percebido e adesão farmacológica em pacientes submetidos à intervenção coronária percutânea.

The objectives of this study were to evaluate the perceived health status and pharmacological adherence, and to verify the correlation between these measures in patients who underwent percutaneous coronary intervention, after hospital discharge. It was a cross-sectional study carried out from May 2011 to July 2012. The instruments used were: SF-86 and Measurement of Adherence to Treatment, with 101 patients, 54 (53.5%) of which were men; average age of 59.5 +/- 10.3; and 32 (32.7%) with previous cardiac treatment. All study participants were using antihypertensive drugs; the majority 99 (98%) used antiplatelet drugs; 98 (97%) used cholesterol reducers, and 59 (58.4%) used coronary vasodilators. The average number of drugs used was 6.8 +/- 2.1. Pharmacological adherence was observed in 98 (97%) patients. The participants presented best perceived health status in Social Functioning and Physical Functioning. Positive correlations of moderate magnitude were found between measurements of pharmacological adherence and Physical Functioning, General Health and Social Functioning. There was correlation between pharmacological adherence and perceived health status.

The effect of white matter lesions on cognition after carotid revascularization.

BACKGROUND: Cerebral white matter lesions (WML) are associated with cognitive impairment, and carotid revascularization with cognitive worsening or improvement. We assessed the relation between WML severity and changes in cognition after carotid endarterectomy or stenting. METHODS: Patients with symptomatic carotid artery stenosis, enrolled in the International Carotid Stenting Study (ISRCTN25337470), underwent detailed neuropsychological examinations (NPEs) before and after 6 months. Cognitive results were standardized into z-scores, from which a sum score was calculated. The primary outcome was the mean difference (MD) in sum score between baseline and follow-up. Changes in sum score were related to WML severity with the 'age-related white matter changes' score, assessed on baseline MRI-FLAIR. Three groups were formed based on this score. RESULTS: Eighty-nine patients had both baseline MRI and NPE, of these 77 had a calculable cognitive difference score. The cognitive sum score at six months was worse than at baseline: MD, -0.21; 95% CI, -0.32 to -0.09. The change in sum score did not depend on WML load: MD for no-to-mild WML, -0.15; 95% CI, -0.39 to 0.09, for moderate WML, -0.27; 95% CI, -0.48 to -0.06; and for severe WML, -0.21; 95% CI, -0.40 to -0.04. This did not change essentially after adjustment for baseline factors. CONCLUSION: Cognitive functioning deteriorated after carotid revascularization, regardless of baseline WML burden.

Impact of palliative urinary diversion by percutaneous nephrostomy drainage and ureteral stenting among patients with advanced cervical cancer and obstructive uropathy: a prospective cohort.

AIM: Obstructive uropathy is a recognized complication in advanced cervical cancer. Urinary diversion is commonly used to bypass the obstruction and improve renal function. The degree of survival benefit that diversion offers is not well established and its impact on quality of life (QoL) is uncertain. This study considered these factors in order to inform treatment decisions. METHODS: This study examined a prospective cohort of patients with advanced cervical cancer and obstructive uropathy in Manila, Philippines. Age, cancer treatment status, comorbidities, serum creatinine level, degree of obstructive uropathy and QoL were recorded at baseline. Patients with creatinine values >150 µmol/L, or who were being considered for radiotherapy or nephrotoxic chemotherapy or manifesting uncontrolled or recurrent uropathy-related urinary tract infection, were offered diversion. Follow-up data collection was at 3, 6, 9 and 12 months from cohort entry. RESULTS: Of the 230 patients invited, 205 patients joined the cohort. Complete data were available for 198, of whom 93 underwent diversion, 56 required diversion but elected not to receive it, and 49 did not require it. Although survival at 12 months among those who underwent diversion was no greater than among those who required but elected not to receive the procedure, diversion was associated with significantly improved chance of survival in the shorter term. There was no significant difference in the QoL between the groups throughout the study. CONCLUSION: With no evidence of an impact on QoL, the decision to offer diversionary surgery might be based solely on a survival benefit, which is modest but potentially important to patients.

Predictors of survival in patients with malignant gastric outlet obstruction: a patient-oriented decision approach for palliative treatment.

BACKGROUND: Gastrojejunostomy and stentplacement are the most commonly used treatments for malignant gastric outlet obstruction (GOO). The preference for either treatment largely depends on the expected survival. Our objective was to investigate predictors of survival in patients with malignant GOO and to develop a model that could aid in the decision for either gastrojejunostomy or stentplacement. METHODS: Prognostic factors for survival were collected from a literature search and evaluated in our patient population, which included 95 retrospectively and 56 prospectively followed cases. All 151 patients were treated with gastrojejunostomy or stentplacement. RESULTS: A higher WHO performance score was the only significant prognostic factor for survival in our multivariable analysis (HR 2.2 95%CI 1.7-2.9), whereas treatment for obstructive jaundice, gender, age, metastases, weight loss, level of obstruction and pancreatic cancer were not. A prognostic model that includes the WHO score was able to distinguish patients with a poor survival (WHO score 3-4, median survival: 31 days) from those with a relatively intermediate or good survival (WHO score 2, median survival: 69 and WHO score 0-1, median survival: 139 days, respectively). CONCLUSIONS: Only the WHO score is a significant predictor of survival in patients with malignant GOO. A simple prognostic model is able to guide the palliative treatment decision for either gastrojejunostomy (WHO score 0-1) or stentplacement (WHO 3-4) in patients with malignant GOO.

Response shift in the assessment of quality of life among people attending cardiac rehabilitation.

OBJECTIVES: To examine whether any response shift in quality of life (QoL) assessment over the course of a cardiac rehabilitation (CR) programme could be explained by changes in individuals' internal standards (recalibration), values (reprioritization), and/or conceptualization of QoL and the extent to which any response shift could be explained by health locus of control, optimism, and coping strategy. DESIGN: Longitudinal survey design. METHODS: The schedule for evaluation of individual QoL-direct weighting (SEIQoL-DW) was administered at the beginning and end of a CR programme. At the end of the programme, the SEIQoL-DW then-test was also administered to measure response shift. A total of 57 participants completed these measures and other measures to assess health locus of control, optimism, and coping. RESULTS: Response shift effects were observed in this population mainly due to recalibration. When response shift was incorporated into the analysis of QoL a larger treatment effect was observed. Active coping as a mechanism in the response shift model was found to have a significant positive correlation with response shift. CONCLUSION: This study showed that response shift occurs during CR. The occurrence of response shift in QoL ratings over time for this population could have implications for the estimation of the effectiveness of the intervention.

Chest symptoms following coronary stenting in the first 10 weeks of recovery.

BACKGROUND: Most patients experience the benefits of PTCA and stent quickly, with reduction in symptoms and improvement in functional status, however many patients experience chest symptoms post-procedure. OBJECTIVE: To describe the pattern and characteristics of post-stent chest symptoms in cardiac rehabilitation participants. METHODS: A prospective descriptive study assessing the pattern and presence of chest symptoms in coronary artery stent recipients (N=129) four and ten weeks post-procedure. Patients were interviewed at cardiac rehabilitation or by the phone using a specifically developed questionnaire which incorporated the McGill Pain Questionnaire. RESULTS: Most participants were male, aged on average 60.5 years and received two stents, most often drug eluting. Post-stent chest symptoms were common, experienced by two thirds of patients (68%) at some time during the 10 weeks post-discharge. Chest symptoms were recurrent, with 33% having symptoms on both occasions and occurred more often in younger patients (p<.00). Patients described their symptoms as discomforting and used the descriptors dull, tight, sharp, pressing and flickering. Chest symptoms tended to be brief and/or intermittent (65%) lasting from a few seconds to a few minutes (63%). Most patients felt their symptoms were related to their stent (75%) and were unsure what to do. A small number (5%) interpreted their symptoms as ischaemic and presented to the hospital (4%). CONCLUSIONS: Post-stent chest symptoms are frequent and recurrent out to 10 weeks post-discharge. Although symptoms tended to be brief and intermittent, the location and quality of these symptoms may overlap with existing chest pain guidelines, making it difficult for patients to interpret. Cardiac rehabilitation staff are in an ideal position to support and inform stent recipients about appropriate responses to these symptoms.

Indwelling ureteral stents and sexual health: a prospective, multivariate analysis.

PURPOSE: Ureteral stents are common devices in urological practice. However, a stent may provoke lower urinary tract symptoms that severely affect quality of life. We evaluated the relationship between ureteral stents and male erection/female sexuality. MATERIALS AND METHODS: A total of 30 men and 20 women undergoing ureteral stent positioning were considered. Patients affected by risk factors for erectile dysfunction or hormonal and metabolic alterations were excluded. Hystero-ovariectomy and menopause were considered exclusion criteria. Three questionnaires were administered before stenting and 45 to 60 days after stent positioning, including the International Prostate Symptom Score, the International Index of Erectile Function-5 for men and the Female Sexual Function Index for women. RESULTS: Mean age was 45 years in men and 39 years in women. The mean+/-SD International Index of Erectile Function-5 score was 23.2+/-1.27 and the mean Female Sexual Function Index score was 32.15+/-2.71 before stent positioning. No lower urinary tract symptoms were reported before the procedure. After the ureteral stent was indwelling the mean International Index of Erectile Function-5 score was 13.5+/-4.01 and the mean Female Sexual Function Index score was 23.6+/-14.66 (p=0.000 and 0.007, respectively). Of 30 men 25 reported a pathological International Index of Erectile Function-5 score and 6 of 20 women denied any sexual activity due to stent related anxiety, resulting in the minimum Female Sexual Function Index score. In the remaining 14 women sexual life was not significantly impaired by the ureteral stent (p=0.08). CONCLUSIONS: Ureteral stents impaired the quality of sexual life in male and female subjects. In men the most important distress was in regard to erectile function, probably related to lower urinary tract symptoms. Conversely female sexuality appeared to be severely impaired due to stent related psychological concerns.

Clinical life: expectation and the double edge of medical promise.

This article introduces the concept of clinical life to capture a form of life produced in the pursuit and wake of medically achieved longevity. Relying on the retrospective accounts of 28 individuals over age 70 who have undergone cardiac bypass surgery, angioplasty or a stent procedure, as well as interviews with their families and with clinicians, we examine three features of clinical life. First, patients do not distinguish between clinical possibility and clinical promise, and thus assume that life can and will be improved by medical intervention in late life. Rather than anticipating a range of potential treatment outcomes, patients therefore expect the best-case scenario: that medical procedures will reverse aging, disease and the march of time. Second, patients then assess the value of their post-procedure lives in accordance with that expectation. Norms regarding what life 'should be like' at particular ages are continually recalibrated to the horizon of what is clinically possible. And third, the price of living longer entails a double-edged relationship with the clinic--it generates opportunities for bodily restoration and increased self-worth but also creates ambivalence about the value of life. This latter feature of clinical life is rarely publicly acknowledged in an environment that emphasizes medical promise.

Quality of life improves after renal artery stenting.

Although treatment of renal artery stenosis (RAS) with stents has been shown to improve blood pressure (BP) and renal function in some patients, little is known about the effect on health-related quality of life. A composite quality of life survey was administered in a cross-sectional cohort fashion to 149 patients presenting with angiographically and hemodynamically confirmed RAS either before (baseline, n = 37) or after (follow-up, n = 112) stent revascularization. BP, renal function, and antihypertensive medication use were also assessed. Systolic BP was lower in the revascularized patients (166 +/- 23 vs. 153 +/- 26, p < .01). The Short Form-36 Physical Component Summary (PCS) scores were higher (better) in revascularized patients (37 +/- 9 vs. 31 +/- 9, p < .01), whereas Mental Component Summary scores were equivalent (49 +/- 13 vs. 51 +/- 11, p = ns). Sleep dysfunction scores were lower (better) in the revascularized patients (32 +/- 26 vs. 48 +/- 32, p < .001), whereas self-reported appetite was higher (better; 62% +/- 29% vs. 73% +/- 27%,p < .05). After matching for age and gender, Short Form-36 PCS remained higher in the revascularized cohort (37 +/- 8 vs. 32 +/- 8, p < .05). Importantly, in multivariate analysis, revascularization was the most significant determinant of a higher PCS score (r2 = .07, beta = 5.21, p < .01). The current data suggest that renal artery stenting may improve health-related quality of life in patients with renovascular disease.

Moving beyond the cost per quality-adjusted life year: modelling the budgetary impact and clinical outcomes associated with the use of sirolimus-eluting stents.

Restenosis is a major limitation to the long-term success of percutaneous coronary intervention. Drug-eluting stents are the most recent technological advance in restenosis prevention. While they are effective, their use is associated with a significant incremental cost, and a recent economic evaluation performed by the authors suggested that their use is associated with a cost per quality-adjusted life year of $58,721. How should decision-makers react to this value, particularly given that the use of sirolimus-eluting stents appears more attractive in certain patient subgroups, such as those with complex coronary lesions? In the present paper, the authors explore an alternative method of presenting the results of their economic evaluation, rather than the usual cost per quality-adjusted life year rubric, in an attempt to assist decision-makers in deciding whether, and for whom, to fund sirolimus-eluting stents. Several issues that decision-makers and providers may wish to consider when making such funding decisions are discussed.

[Quality of life following percutaneous coronary interventions in octogenarians]. / Perkutane Koronarinterventionen verbessern die Lebensqualität von Patienten nach dem 80. Lebensjahr.

BACKGROUND: Percutaneous coronary interventions (PCI) are increasingly performed in elderly patients. However, it is not known whether PCI leads to symptomatic relief comparable to that in younger patients. PATIENTS AND METHODS: 55 Patients aged 80 years or above with stable angina (82 +/- 2 years, 33 males, 22 females) were prospectively compared with younger patients (62 +/- 8 years) regarding their quality of life following PCI. For psychometric evaluation, the German version of the SF-36 Health Survey was used. RESULTS: Prior to angioplasty, there was significant physical pain, a perception of reduced general health and a significant limitation of physical activity in both groups. The number of diseased vessels was 2.7 +/- 0.6 in octogenarian patients vs. 2.6 +/- 0.7 in control patients; interventions were performed in 1.1 +/- 0.3 vs. 1.0 +/- 0.2 vessels and in 1.3 +/- 0.7 vs. 1.3 +/- 0.5 lesions. Frequency of stent implantation was 0.9 +/- 0.3 per lesion in both groups. Success rates were comparable in both groups (94 % vs. 97 %), as well as complication rates In both groups 6 months after angioplasty, bodily pain had decreased, the perception of general health and the ability to fulfill physical role expectations had improved. The effects on bodily pain and on the ability to fulfill physical role expectations were more pronounced in octogenarian patients. CONCLUSIONS: Our study shows that PCI improves quality of life in octogenarian patients with stable angina without excessive risk. The benefits of PCI were, in some aspects, even more pronounced than in younger patients.

Biomedical and psychosocial predictors of anginal frequency in patients following angioplasty with and without coronary stenting.

This study examined the contribution of biomedical and psychological variables in the report of anginal frequency at 6-week, 6- and 12-month follow-up in patients who received angioplasty with and without stent. Patients (N = 70) completed a battery of standardized questionnaries, including measures of depression, anxiety, and anger. Principal components analysis computed a single factor of negative emotion for use as a predictor in regression analyses. For the 6-week model, only baseline anginal frequency predicted anginal frequency. Negative emotion joined baseline anginal frequency in the prediction model for 6-month anginal frequency, and collectively accounted for 23% of the variance. For the 12-month model, baseline anginal frequency, female sex, and negative emotions remained in the model, accounting for 46% of the variance in anginal frequency. These results highlight the importance of biomedical and psychosocial variables in predicting anginal frequency with psychological variables sustaining predictive value over the course of recovery.
