RESUMO
Inflammation is involved in initiation and progression of aortic stenosis (AS). However, the role of the complement system, a crucial component of innate immunity in AS, is unclear. We hypothesized that circulating levels of complement factor B (FB), an important component of the alternative pathway, are upregulated and could predict outcome in patients with severe symptomatic AS. Therefore, plasma levels of FB, Bb, and terminal complement complex were analyzed in three cohorts of patients with severe symptomatic AS and mild-to-moderate or severe asymptomatic AS (population 1, n = 123; population 2, n = 436; population 3, n = 61) and in healthy controls by enzyme immunoassays. Compared with controls, symptomatic AS patients had significantly elevated levels of FB (2.9- and 2.8-fold increase in population 1 and 2, respectively). FB levels in symptomatic and asymptomatic AS patients were comparable (population 2 and 3), and in asymptomatic patients FB correlated inversely with valve area. FB levels in population 1 and 2 correlated with terminal complement complex levels and measures of systemic inflammation (i.e., CRP), cardiac function (i.e., NT-proBNP), and cardiac necrosis (i.e., Troponin T). High FB levels were significantly associated with mortality also after adjusting for clinical and biochemical covariates (hazard ratio 1.37; p = 0.028, population 2). Plasma levels of the Bb fragment showed a similar pattern in relation to mortality. We concluded that elevated levels of FB and Bb are associated with adverse outcome in patients with symptomatic AS. Increased levels of FB in asymptomatic patients suggest the involvement of FB from the early phase of the disease.

BACKGROUND: Studies on the effect of high-intensity interval training (HIT) compared with moderate intensity continuous training (MICT) on health-related quality of life (HRQoL) after heart transplantation (HTx) is scarce. No available studies among de novo HTx recipients exists. This study aimed to investigate the effect of HIT vs. MICT on HRQoL in de novo recipients. METHODS: The HITTS study randomized eighty-one de novo HTx recipients to receive either HIT or MICT (1:1). The HIT intervention were performed with 2-4 interval bouts with an intensity of 85-95% of maximal effort. The MICT group exercised at an intensity of 60-80% of their maximal effort with a duration of 25 min. HRQoL was assessed by the Short Form-36 version 2 (SF-36v2) and the Hospital Anxiety and Depression Scale, mean 11 weeks after surgery and after a nine months' intervention. The participants recorded their subjective effect of the interventions on their general health and well-being on a numeric visual analogue scale. Clinical examinations and physical tests were performed. Differences between groups were investigated with independent Student t-tests and with Mann-Whitney U tests where appropriate. Within-group differences were analyzed with Paired-Sample t-tests and Wilcoxon Signed Rank tests. Correlations between SF-36 scores and VO2peak were examined with Pearson's correlations. RESULTS: Seventy-eight participants completed the intervention. Both exercise modes were associated with improved exercise capacity on the physical function scores of HRQoL. Mental health scores remained unchanged. No differences in the change in HRQoL between the groups occurred except for Role Emotional subscale with a larger increase in the HIT arm. Better self-reported physical function was associated with higher VO2peak and muscle strength. CONCLUSION: HIT and MICT resulted in similar mean changes in HRQoL the first year after HTx. Both groups experienced significant improvements in the physical SF-36v2. TRIAL REGISTRATION: ClinicalTrials.gov number: NCT01796379 Registered 18 February 2013.

BACKGROUND AND AIM OF THE STUDY: Aortic valve replacement (AVR) improves survival and quality of life in patients with severe aortic stenosis (AS), but despite clear indications for surgical treatment a significant proportion of patients do not undergo AVR. The study aim was to identify clinical variables associated with the decision to perform AVR, and to assess the prognostic effect of surgery versus medical treatment in patients with severe AS adjusted for significant confounders and effect modifiers. METHODS: A prospective observational study of consenting patients aged >18 years who were under consideration for AVR at the authors' tertiary teaching hospital was conducted. The main outcomes of the study were treatment decisions and survival. RESULTS: Among 480 patients with severe AS who were evaluated, 351 had surgical AVR, 38 had transcatheter AVR, and 91 were declined operative treatment. Typically, non-operated patients were older, were in a lower NYHA class, had fewer symptoms, a lower peak aortic jet velocity, a higher NT-proBNP level, and a lower physical summary score (SF-36). Higher age showed the strongest correlation against AVR (OR 0.91; 95% CI 0.87-0.94). One-, three-, and five-year cumulative survival rates, respectively, were 95%, 87%, and 73% among operated patients, and 82%, 47%, and 27% among non-operated patients. The median survival time was 1,604 days (95% CI 1,554-1,655) in operated patients versus 1,090 days (95% CI 954-1,226) in non-operated patients (p <0.001). The effect of operation on mortality was shown to depend on the interaction with diabetes, when adjusted for significant confounders (i.e., age, atrial fibrillation, NT-proBNP, hs-Troponin T, and NYHA class). An effect of AVR on mortality was found in patients without diabetes (HR 0.29; 95% CI 0.19-0.468; p <0.001), but not among patients with diabetes. CONCLUSIONS: Supplemental and better parameters to improve patient selection are warranted. Surgical AVR shows a greater prognostic effect in patients without diabetes.

PURPOSE: Standard gamble (SG) is the preferred method of assessing preferences in situations with uncertainty and risk, which makes it relevant to patients considered for aortic valve replacement (AVR). The present study assesses SG preferences in patients with severe aortic stenosis (AS). METHODS: All patients >18 years old with severe AS referred for AVR to our institution were invited to enroll in the study. The SG was administered by a clinical research nurse. The SF-36, EQ-5D 3L, Hospital Anxiety and Depression Scale (HADS), and AS symptoms were administered by self-completed questionnaire. We hypothesized that SG utilities would have low-to-moderate correlations with physical and mental aspects of health based on our pathophysiological understanding of severe AS. No correlations were expected with echocardiographic measures of the aortic valve. RESULTS: The response rate for SG was 98 %. SG moderately correlated with physical aspects of SF-36 (PCS, role-physical, vitality), health transition, AS symptoms, and EQ-VAS (ρ S = 0.31-0.39, p < 0.001) and had low correlation with mental aspects of SF-36 and EQ-5D (ρ S = 0.17-0.28, p < 0.001). No correlation was found between SG and HADS, echocardiographic measures, age, gender, or education level (ρ S = 0.01-0.06). CONCLUSIONS: SG is an acceptable and feasible method of assessing preferences in patients with severe AS that has evidence for validity. The inclusion of uncertainty lends the SG face validity in this population as a direct approach to assessing preferences and basis for QALY calculations.

BACKGROUND: The objective was to explore the relationship between left ventricular ejection fraction (LVEF) assessed during hospitalization for acute myocardial infarction (MI) and later health-related quality of life (HRQoL). METHODS: We used multivariable linear regression to assess the relationship between LVEF and HRQoL in 256 MI patients who responded to the Kansas City Cardiomyopathy Questionnaire (KCCQ), the EQ-5D Index, and the EuroQol Visual Analogue Scale (EQ-VAS) 2.5 years after the index MI. RESULTS: 167 patients had normal LVEF (>50%), 56 intermediate (40%-50%), and 33 reduced (<40%). The mean (SD) KCCQ clinical summary scores were 85 (18), 75 (22), and 68 (21) (p <0.001) in the three groups, respectively. The corresponding EQ-5D Index scores were 0.83 (0.18), 0.72 (0.27), and 0.76 (0.14) (p = 0.005) and EQ-VAS scores were 72 (18), 65 (21), and 57 (20) (p = 0.001). In multivariable linear regression analysis age > or = 70 years, known chronic obstructive pulmonary disease (COPD), subsequent MI, intermediate LVEF, and reduced LVEF were independent determinants for reduced KCCQ clinical summary score. Female sex, medication for angina pectoris at discharge, and intermediate LVEF were independent determinants for reduced EQ-5D Index score. Age > or = 70 years, COPD, and reduced LVEF were associated with reduced EQ-VAS score. CONCLUSION: LVEF measured during hospitalization for MI was a determinant for HRQoL 2.5 years later.

OBJECTIVES: This study addressed the assumption of increased morbidity and mortality after surgical aortic valve replacement in patients older than 80 years with severe aortic stenosis. METHODS: This prospective study was performed in consecutive patients referred for aortic valve replacement. The age-dependent change in cognitive and physical function, quality of life and rehospitalization and complication rates during the following year and 5-year all-cause mortality were documented. RESULTS: A total of 351 patients underwent surgical aortic valve replacement. The death risk at 5 years was 10%, 20% and 34% in patients aged <70 years, 70-79 years and ≥80 years, respectively. Patients aged 70-79 years and ≥80 years had a hazard ratio of 1.88 [95% confidence interval (95% CI) 0.92-3.83, P = 0.08] and 2.90 [95% CI 1.42-5.92, P = 0.003] for mortality, respectively, when compared with patients aged <70 years. The length of stay and rehospitalization rate during the following year were similar between the groups. Patients ≥80 years of age experienced more delirium and infections, whereas the risks of new pacemaker, transient ischaemic attack (TIA) or stroke, myocardial infarction and heart failure were comparable between the age groups. All groups exhibited reduced New York Heart Association class, improved physical quality of life and unchanged mental scores without any clinically significant Mini Mental Status reduction. CONCLUSIONS: Elderly patients (≥80 years of age) have important gains in health measures and satisfactory 5-year survival with an acceptable complications rate during the year following surgery. Active respiratory mobilization and the removal of an indwelling urethra catheter can prevent adverse effects, and measures should be taken to prevent delirium and confusion in elderly patients.

OBJECTIVES: Health-related quality of life (HRQoL) is an important outcome after surgical aortic valve replacement (SAVR). To improve interpretation of HRQoL, mean score change and change in terms of minimal important difference (MID) were assessed using validated instruments for measuring patient-reported outcomes in patients with severe aortic stenosis referred for possible SAVR. METHODS: Of the 442 included patients with severe aortic stenosis evaluated for possible SAVR, 351 were referred to SAVR (operated) and 91 to medical treatment (unoperated). At presurgical evaluation and 1 year postoperatively, HRQoL was assessed using SF-36v2 and EQ-5D. Results were compared with outcomes reported in unoperated patients. We explored the association of clinical factors and improvements corresponding to MID. RESULTS: Among the operated patients, statistically significant change was found for EQ-5D scores and SF-36 scale scores for physical functioning, role-physical, bodily pain, general health, vitality and physical summary score. The largest proportion of operated patients achieving change corresponding to at least MID was 61.5% for physical summary score. Change in unoperated patients also related largely to physical scales of the SF-36. However, smaller proportions of unoperated patients reported improvements, and larger proportions reported decline reaching MID. Baseline scores, but no clinical covariates, were consistently associated with improved HRQoL reaching MID across instruments for those referred to SAVR. CONCLUSIONS: This study found improvement in HRQoL 1 year after SAVR for patients with severe aortic stenosis. Results in unoperated patients suggest that HRQoL deteriorates 1 year after evaluation of possible SAVR. CLINICAL TRIAL REGISTRATION: www.clinicaltrials.gov (NCT01794832).

BACKGROUND: Treatment decisions for aortic valve replacement (AVR) should be sensitive to patient preferences. However, we lack knowledge of patient preferences and how to obtain them. METHODS AND RESULTS: We assessed the mortality risk patients were willing to accept when undergoing AVR by using the Standard Gamble method and aimed to show how this risk willingness was affected by level of disease burden. We report findings from 439 patients, aged >18 years with severe aortic stenosis who were referred for evaluation of AVR to our institution. The vast majority of patients accepted a mortality risk regarded as high or prohibitive according to current guidelines. Of the 439 patients, 51% patients were willing to forego surgery with high mortality risk (8-50%) and 19% were willing accept a prohibitive mortality risk (>50%) as defined in current guidelines. However, the risk willingness varied considerably. Acceptance of prohibitive risk willingness (>50%) was associated with reporting of 3 to 5 different restricting symptoms, with an odds ratio of 4.07 (95% CI 1.56-10.59) opposed by increasing score on EuroQol-Visual Analog Scale, with an odds ratio of 0.99 (95% CI 0.97-1.00). The poor ability to predict risk willingness based on available clinical variables and health status suggests that other factors may be important advocating the need for tools for soliciting patient's preferences individually. CONCLUSION: When undergoing AVR, patients were willing to accept considerably higher perioperative risk than what is considered acceptable in current guidelines and practice. Patient preferences varied considerably, and they should be directly assessed and taken into account in decision-making and guidelines. CLINICAL TRIAL REGISTRATION: URL: https://clinicaltrials.gov/.

BACKGROUND: The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a recently developed disease-specific instrument for measuring health-related quality of life (HRQoL) in patients with chronic heart failure (CHF) regardless of aetiology. AIM: To assess the reliability and validity of the KCCQ in patients with previous myocardial infarction (MI). METHODS AND RESULTS: In 754 myocardial infarction patients who were discharged alive, we collected clinical data from the patients' medical records. Two and a half years after the acute myocardial infarction, we mailed a self-administered questionnaire to the 548 patients still alive. The response rate was 74%. Internal consistency reliability, assessed with Cronbach's alpha, ranged 0.66-0.95. Test-retest reliability, tested with an intraclass correlation coefficient (ICC), ranged 0.41-0.83. The pattern of association between similar and dissimilar scales of the KCCQ and Short Form 36 (SF-36) supported the convergent/divergent validity of the KCCQ. Four of the KCCQ scales and the two summary scores discriminated between patients with and without medication for heart failure, and between different levels of left ventricular ejection fraction (LVEF) supporting different groups validity. CONCLUSIONS: The Norwegian version of the KCCQ showed acceptable reliability and cross-sectional validity, which support the use of this questionnaire to measure health-related quality of life after myocardial infarction.

BACKGROUND: Few studies have focused on the association between the sociodemographic characteristics of a patient with the change in health-related quality of life (HRQOL) following invasive coronary procedures, and the results remain inconclusive. The objective of the present study was to measure the temporal changes in HRQOL of patients with coronary heart disease, and assess how these changes are associated with invasive coronary procedures and sociodemographic characteristics. METHODS: This was a prospective study of 254 patients with angina pectoris and 90 patients with acute coronary syndrome. HRQOL was assessed with the multi-item scales and summary components of the SF-36, both 6 weeks and 2 years after baseline hospitalization in 1998. Paired t-tests and multiple regression analyses were used to assess temporal changes in HRQOL and to identify the associated factors. RESULTS: Physical components of HRQOL had improved most during the 2 years following invasive coronary procedures. Our findings indicated that patients with angina pectoris who were younger, male, and more educated were most likely to increase their HRQOL following invasive coronary procedures. When adjusting for baseline HRQOL scores, invasive coronary procedures and sociodemographic characteristics did not explain temporal changes in patients with acute coronary syndrome, possibly due to higher comorbidity. CONCLUSION: Sociodemographic characteristics should be taken into account when comparing and interpreting changes in HRQOL scores in patients with and without invasive coronary procedures.

BACKGROUND: Patient experience has been identified as a national indicator of hospital quality. We describe the changes in patient experiences 1996-2000 for seven Norwegian hospitals. MATERIAL AND METHODS: A patient experience questionnaire was sent to medical and surgical patients in a stratified random sample of hospitals in 1996. The same questionnaire was used in similar surveys in 1998 and 2000. Responses from hospital wards included in all three surveys were compared on ten summated rating scales. Changes were identified by multiple linear regression. RESULTS: Responses from a total of 10 600 patients were analysed. For six scales no change was noted: general satisfaction, information on medication, information on examinations, nursing services, doctor services, and organization. Statistically significant improvement was found for three indices: communication, contact with next-of-kin, and information regarding future complaints. For one scale, scores changed for the worse: hospital and equipment. All changes were small. INTERPRETATION: Patient experiences with Norwegian hospitals did not change much between 1996 and 2000. On some indices, our data indicate slight improvement. Patient assessment of buildings and equipment changed negatively.

BACKGROUND: The role of sex differences in health-related quality of life (HRQoL) after myocardial infarction (MI) remains controversial. METHODS: In total 408 Norwegian patients completed the Short Form 36 (SF-36) questionnaire 2.5 years after MI. We compared HRQoL between sexes and with national norms. Multiple linear regression analysis was used to explore the association of scores on the Physical (PCS) and Mental (MCS) component summary scales with clinical and sociodemographic variables. RESULTS: Women scored lower than norms on the Physical functioning, Role functioning-physical, General health, and Role functioning-emotional scales. Men scored higher on Bodily pain, and lower on the other 7 scales compared to norms. Women <70 years scored lower than men on 3 out of 8 scales and on PCS. Women >/=70 scored lower than men on 5 out of 8 scales and on PCS. Relative to sex- and age-specific norms, there were no sex-differences in SF-36 scores. Age, time since the index MI, chronic obstructive pulmonary disease (COPD), previous MI, and stroke predicted PCS scores in women. Education, COPD, infarct localization, number of indications for cardiovascular medication at discharge, medication for heart failure, and subsequent MI predicted PCS scores in men. Smoking status, education, and Q-wave MI were determinants for MCS scores in men. CONCLUSION: Patients had impaired HRQoL compared to sex- and age-specific norms 2.5 years after MI. Women had lower HRQoL scores than men, but relative to norms HRQoL was equally affected in both sexes. Men and women had different determinants of HRQoL.

BACKGROUND: High mortality rates have been reported in diabetic patients after acute myocardial infarction (AMI). The excess mortality has been attributed to the diabetic state itself. We aimed to investigate how other risk factors along with diabetes per se may predict mortality in an unselected AMI population. METHODS: A representative sample of an unselected AMI population was collected over a three-month period. Data on patients' histories, co-morbidity, presenting features and treatment were collected from medical records. The data sets included outcome variables at discharge, after 6 months and after 2.5 years. Patients with confirmed diabetes on admission to hospital were registered as diabetic patients. RESULTS: Of the 901 patients admitted to hospital with AMI, 121 (14%) were diabetic patients. Compared with the nondiabetic patients significantly fewer of the diabetic patients were alive at discharge (78% vs 86%), after 6 months (64% vs 78%) and after 2.5 years (42% vs 65%). In multiple logistic regression analyses adjusted for age, sex and smoking status, the most important predictor of death at 2.5 years was heart failure, followed by previous MI, diabetes, and angina pectoris. The population attributable risk (PAR) of death after 2.5 years was 7% for diabetes, 17% for previous MI, 13% for heart failure and 12% for angina pectoris. CONCLUSION: Among patients with diabetes suffering an AMI the already established cardiovascular co-morbidities, which previously partly or fully might have been caused by diabetes, contributed more than diabetes per se to high mortality in-hospital and in the follow-up period.

AIMS: To assess the association between patient experiences, aspects of healthcare delivery, and patient characteristics for adult somatic inpatients attending hospitals throughout Norway. METHODS: The Patient Experiences Questionnaire (PEQ) was mailed to 26,938 patients attending inpatient clinics at 62 Norwegian hospitals during 2002 and 2003 within a six-week period. Reminders were mailed at four weeks. Scores for the PEQ were regressed on whether the patient felt that he/she had received incorrect treatment, had spent the night in a corridor bed, had been an emergency or routine admission, his/her number of previous admissions, hospital teaching status, hospital size and location, health status, and sociodemographic variables. RESULTS: A total of 13,700 (50.9%) patients responded. Patients who felt that they had received incorrect treatment had significantly poorer scores for all 10 PEQ dimensions. Those spending the night in a corridor bed had significantly poorer scores for six dimensions. Emergency admissions and the previous number of inpatient stays were significantly associated with poorer experiences for 10 and 7 dimensions respectively. Hospital size and university status had negative relationships with scores for six and four dimensions respectively. CONCLUSIONS: Whether the patient felt that he/she had received the incorrect treatment had by far the strongest association with patient experiences. Future studies of patient experiences and satisfaction should include this variable. As found in previous research, patient experiences were significantly associated with age and health status.

PURPOSE: It has not been decided to what extent the results from statin trials should be transferred to clinical practice in the very old. The aim of the study was to assess the use of cardiovascular drugs after an acute myocardial infarction (MI), with particular focus on statins, in very old patients as compared to younger patients. METHOD: A sample of 901 acute MI patients was drawn from 16 hospitals in 1999/2000; the patients were followed up for 2.5 years. Information on demographic variables and drug therapy was obtained from hospital records, and in the follow-up period by direct patient contact or questionnaire. The main indications for prescribing the various cardiovascular drugs were recorded. RESULTS: At discharge, drug use in patients >or=80 and <80 years, respectively, was as follows: ACE-inhibitors 48 versus 32%, nitrates 55 versus 32%, diuretics 64 versus 26%, aspirin 72 versus 86%, and beta-blockers 67 versus 85%. A striking difference was found for statins: 9% in the very old and 72% in younger patients. The pattern of drug use generally remained unchanged after 2.5 years. Survival rates for patients >or=80 and <80 years: at discharge 72 versus 90%, after 2.5 years 34 versus 73%. CONCLUSIONS: Drug therapy was widely accepted for the indication secondary prevention after MI in patients above 80 years of age. The various cardiovascular drugs were prescribed to about the same extent for very old and younger patients. The exception was lipid lowering drugs which, despite the physicians' recognition of the indication secondary prevention in the very old patients, were prescribed to a limited extent.

The aim of this study was to validate the Norwegian version of the Seattle Angina Questionnaire (SAQ), a self-administered 19-item questionnaire designed to assess health-related quality of life in patients with chest pain or coronary artery disease. In 885 patients with prior myocardial infarction (MI), we abstracted clinical data from the patients' medical records. Two to three years after the MI, we mailed a self-administered questionnaire including the SAQ, the Short Form 36 (SF-36), and questions about current medication, to the 548 patients still alive. The response rate was 74%. Internal consistency reliability of the SAQ, assessed with Cronbach's alpha, ranged 0.75-0.92. Test-retest reliability, tested with an intraclass correlation coefficient, ranged 0.29-0.84. The pattern of association between similar and dissimilar scales of the SAQ and SF-36 mainly supported the construct validity of the SAQ. Four of the five SAQ scales discriminated between patients with different medication regimens as a proxy for severity of angina pectoris. We conclude that the Norwegian version of the SAQ showed acceptable reliability and cross-sectional validity following MI, with properties in line with the original US version.

OBJECTIVE: . To describe the development of the Patient Experiences Questionnaire (PEQ) and to evaluate reliability and validity of constructed summed rating scales. DESIGN: Literature review, focus groups and pilot surveys. Two national cross-sectional studies performed in 1996 and 1998. SETTING: Two postal surveys in a national sample of 14 hospitals stratified by geographical region and hospital size. Subjects. Patients consecutively discharged from surgical wards and wards of internal medicine. The surveys included 36 845 patients and 19 578 responded (53%). RESULTS: We constructed 10 summed rating scales based on factor analysis and theoretical considerations: Information on future complaints, Nursing services, Communication, Information examinations, Contact with next-of-kin, Doctor services, Hospital and equipment, Information medication, Organization and General satisfaction. Eight scales had a Cronbach alpha coefficient of >0.70, the remaining two were >0.60. Repeatability was >0.70 for five scales and >0.60 for the remaining scales. CONCLUSIONS: The PEQ is a self-report instrument covering the most important subjects of interest to hospital patients. Results are presented as 10 scales with good validity and reliability. It emphasizes practicability and comprehensibility while at the same time providing sufficient information about domains applicable to most patients admitted to medical and surgical wards.
