RESUMO

Although the prevalence of heart failure has been increasing over time, the presentation of heart failure has been shifting, with a greater proportion of preserved ejection fraction and more slowly progressive symptoms that require recognition in the outpatient setting. These shifts have placed more of the diagnostic responsibility onto primary care physicians, who often are challenged to determine the etiology of common symptoms in patients who often have several other potential reasons for these symptoms. Establishing a diagnosis of heart failure requires a step-wise approach that includes physical exam (looking for multiple signs of hypervolemia), labs (B-type natriuretic peptide levels), and echocardiography (structural and functional measures). Diagnostic algorithms are particularly challenging in patients with obesity, which limits the assessment of intravascular volume on exam, the quality of cardiac imaging, and the diagnostic accuracy of B-type natriuretic peptide levels, which may be falsely low. In these challenging patients, the use of risk scores, invasive testing of intravascular volume, or empiric treatment of hypervolemia may be needed to determine whether symptoms are due to heart failure. Once a diagnosis of heart failure is established, several treatments can be beneficial, from diuretics to relieve congestion to various aspects of guideline-directed medical therapy, some of which vary according to the ejection fraction of the patient. In addition, a diagnosis of heart failure may alter the treatment plan for comorbidities, including selection of anti-hypertensive and glucose-lowering medications, and medical or surgical treatments for obesity. While a diagnosis of heart failure may be challenging in many patients with slowly progressive and non-specific symptoms, early recognition and treatment can be extremely effective at preventing hospitalizations, prolonging survival, and improving quality of life.

RESUMO

BACKGROUND: We sought to describe global patterns in achievement of risk factor control for primary prevention in patients with T2D and explore the association of country's GNI/capita with risk factor control. METHODS: The DISCOVER study is a prospective, observational study of patients with T2D from 38 countries enrolled at initiation of second-line glucose-lowering therapy. We examined achievement of risk factor control (glycosylated hemoglobin <7%, blood pressure <140/90 mmHg, prescription of a statin) at 3 years among those without optimal control at baseline. Countries were stratified by gross national income (GNI)/capita, from 2017). We examined the impact of country GNI/capita with achievement of risk factor control. FINDINGS: Our cohort included 9613 patients with T2D and without baseline cardiovascular disease (mean age 57.2 ± 8.7 years, 47.9% women). At baseline, 6354/7646 patients (83.1%) had suboptimal glucose control, 3449/9200 patients (37.5%) had suboptimal BP control, and 2800/4221 patients (66.7%) were not on an appropriate statin (sample sizes differed due to missing covariate data). Optimal control at 3 years of follow-up was achieved in 41% (glucose), 56% (blood pressure), and 29% (statins) of patients. There was significant variability in achievement of risk factor control across countries but no association between country GNI/capita with achievement of risk factor control (p > 0.08 for all). INTERPRETATION: In a global, prospective study of patients with T2D, we found that cardiovascular risk factor control achievement was suboptimal despite 3 years of follow-up in specialized health care systems. Neither country-level nor patient-level socioeconomic factors fully explained this finding.

RESUMO

BACKGROUND: Clinical trials have demonstrated health status benefit of transcatheter mitral valve repair (TMVr) with MitraClip in patients with mitral valve regurgitation. Real-world site-level variability in health status outcomes for TMVr, and factors associated with this variability, are unknown. METHODS: All patients undergoing TMVr procedure with MitraClip between November 2013 and March 2019 in the Transcatheter Valve Therapy Registry were included. Health status was measured at baseline and 30 days with the Kansas City Cardiomyopathy Questionnaire (KCCQ) Overall Summary (OS) score. Site-level variability in 30-day change in KCCQ-OS was examined by calculating the median odds ratio from a hierarchical logistic regression model, with ≥20-point improvement as the dependent variable. To define the extent to which patient characteristics, procedural characteristics (residual mitral valve regurgitation, periprocedural bleeding), site volume, and patients' baseline health status accounted for variability in outcomes, the proportion of variability (R2) explained by sequentially adding these variables to the model was quantified. RESULTS: Across 339 sites, 12 415 patients (mean age 79.0±9.5 years, 46.1%. females, 89.5% White) completed baseline and 30-day health status assessments. Mean KCCQ-OS score was 43.0±24.4 at baseline and 67.0±24.9 at 30-day follow-up. Across sites, the proportion of patients achieving a ≥20-point improvement in KCCQ-OS ranged from 12.5% to 100% and the adjusted median odds ratio was 1.58 (95% CI, 1.46-1.69). The greatest contribution to the variability in health status outcomes was from patients' baseline KCCQ-OS score (R2=25%) with <1% of the variability explained by patient and procedural characteristics, and annual site volume. CONCLUSIONS: There is moderate variation across sites in their patients' achievement of health status benefits from TMVr, with patient's baseline health status accounting for the largest proportion of this variation. This underscores the importance of patient selection in supporting more consistent health status benefit from TMVr.

RESUMO

BACKGROUND: In patients with transthyretin amyloid cardiomyopathy, tafamidis reduces all-cause mortality and cardiovascular hospitalizations and slows decline in quality of life compared with placebo. In May 2019, tafamidis received expedited approval from the US Food and Drug Administration as a breakthrough drug for a rare disease. However, at $225 000 per year, it is the most expensive cardiovascular drug ever launched in the United States, and its long-term cost-effectiveness and budget impact are uncertain. We therefore aimed to estimate the cost-effectiveness of tafamidis and its potential effect on US health care spending. METHODS: We developed a Markov model of patients with wild-type or variant transthyretin amyloid cardiomyopathy and heart failure (mean age, 74.5 years) using inputs from the ATTR-ACT trial (Transthyretin Amyloidosis Cardiomyopathy Clinical Trial), published literature, US Food and Drug Administration review documents, healthcare claims, and national survey data. We compared no disease-specific treatment ("usual care") with tafamidis therapy. The model reproduced 30-month survival, quality of life, and cardiovascular hospitalization rates observed in ATTR-ACT; future projections used a parametric survival model in the control arm, with constant hazards reduction in the tafamidis arm. We discounted future costs and quality-adjusted life-years by 3% annually and examined key parameter uncertainty using deterministic and probabilistic sensitivity analyses. The main outcomes were lifetime incremental cost-effectiveness ratio and annual budget impact, assessed from the US healthcare sector perspective. This study was independent of the ATTR-ACT trial sponsor. RESULTS: Compared with usual care, tafamidis was projected to add 1.29 (95% uncertainty interval, 0.47-1.75) quality-adjusted life-years at an incremental cost of $1 135 000 (872 000-1 377 000), resulting in an incremental cost-effectiveness ratio of $880 000 (697 000-1 564 000) per quality-adjusted life-year gained. Assuming a threshold of $100 000 per quality-adjusted life-year gained and current drug price, tafamidis was cost-effective in 0% of 10 000 probabilistic simulations. A 92.6% price reduction from $225 000 to $16 563 would be necessary to make tafamidis cost-effective at $100 000/quality-adjusted life-year. Results were sensitive to assumptions related to long-term effectiveness of tafamidis. Treating all eligible patients with transthyretin amyloid cardiomyopathy in the United States with tafamidis (n=120 000) was estimated to increase annual healthcare spending by $32.3 billion. CONCLUSIONS: Treatment with tafamidis is projected to produce substantial clinical benefit but would greatly exceed conventional cost-effectiveness thresholds at the current US list price. On the basis of recent US experience with high-cost cardiovascular medications, access to and uptake of this effective therapy may be limited unless there is a large reduction in drug costs.

RESUMO

BACKGROUND: The COAPT trial (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients With Functional Mitral Regurgitation) demonstrated that edge-to-edge transcatheter mitral valve repair (TMVr) with the MitraClip resulted in reduced mortality and heart failure hospitalizations and improved quality of life compared with maximally tolerated guideline-directed medical therapy (GDMT) in patients with heart failure and 3 to 4+ secondary mitral regurgitation. Whether TMVr is cost-effective compared with GDMT in this population is unknown. METHODS: We used data from the COAPT trial to perform a formal patient-level economic analysis of TMVr+GDMT versus GDMT alone for patients with heart failure and 3 to 4+ secondary mitral regurgitation from the perspective of the US healthcare system. Costs for the index TMVr hospitalization were assessed using a combination of resource-based accounting and hospital billing data (when available). Follow-up medical care costs were estimated on the basis of medical resource use collected during the COAPT trial. Health utilities were estimated for all patients at baseline and 1, 6, 12, and 24 months with the Short Form Six-Dimension Health Survey. RESULTS: Initial costs for the TMVr procedure and index hospitalization were $35 755 and $48 198, respectively. Although follow-up costs were significantly lower with TMVr compared with GDMT ($26 654 versus $38 345; P=0.018), cumulative 2-year costs remained higher with TMVr because of the upfront cost of the index procedure ($73 416 versus $38 345; P<0.001). When in-trial survival, health utilities, and costs were modeled over a lifetime horizon, TMVr was projected to increase life expectancy by 1.13 years and quality-adjusted life-years by 0.82 years at a cost of $45 648, yielding a lifetime incremental cost-effectiveness ratio of $40 361 per life-year gained and $55 600 per quality-adjusted life-year gained. CONCLUSIONS: For symptomatic patients with heart failure and 3 to 4+ secondary mitral regurgitation, TMVr increases life expectancy and quality-adjusted life expectancy compared with GDMT at an incremental cost per quality-adjusted life-year gained that represents acceptable economic value according to current US thresholds.

RESUMO

Generalizability of findings from cardiovascular outcomes trials (CVOTs) to patients with type 2 diabetes (T2D) in clinical practice is unknown. We assessed the proportions of patients in the Diabetes Collaborative Registry who would have met enrolment criteria for pivotal CVOTs of sodium-glucose co-transporter-2 inhibitors (SGLT-2is): EMPA-REG OUTCOME, CANVAS, DECLARE and VERTIS CV. In 172 643 patients, mean [standard deviation (SD)] age and HbA1c were 68.1 (11.8) years and 7.8% (2.2), respectively; 56.8% of patients were men and SGLT-2i use was 4.4%. Atherosclerotic cardiovascular disease (ASCVD) prevalence was 64.3% and mean 10-year ASCVD risk was 28.6% in patients without ASCVD. Proportions of patients eligible for CVOTs ranged from 26% (EMPA-REG OUTCOME) to 44% (DECLARE); 48% of patients were ineligible for all CVOTs. Mean (SD) ASCVD risk was 25.4% (22.6), 32.1% (20.6) and 37.7% (19.4) in patients eligible for no, one or two CVOTs, respectively. SGLT-2i use was low in patients eligible for no CVOTs (3.5%) and at least one CVOT (5.2%). In conclusion, applicability of CVOT results to patients with T2D in clinical practice varies based on trial eligibility criteria.

RESUMO

OBJECTIVES: The aim of this study was to describe the costs of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) and the association of complications during CTO PCI with costs and length of stay (LOS). BACKGROUND: CTO PCI generally requires more procedural resources and carries higher risk for complications than PCI of non-CTO vessels. The costs of CTO PCI using the hybrid approach have not been described, and no studies have examined the impact of complications on in-hospital costs and LOS in this population. METHODS: Costs were calculated for 964 patients in the 12-center OPEN-CTO (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion Hybrid Procedures) registry using prospectively collected resource utilization and billing data. Multivariate models were developed to estimate the incremental costs and LOS associated with complications. Attributable costs and LOS were calculated by multiplying the independent cost of each event by its frequency in the population. RESULTS: Mean costs for the index hospitalization were $17,048 ± 9,904; 14.5% of patients experienced at least 1 complication. Patients with complications had higher mean hospital costs (by $8,603) and LOS (by 1.5 days) than patients without complications. Seven complications were independently associated with increased costs and 6 with LOS; clinically significant perforation and myocardial infarction had the greatest attributable cost per patient. Overall, complications accounted for $911 per patient in hospital costs (5.3% of the total costs) and 0.2 days of additional LOS. CONCLUSIONS: Complications have a significant impact on both LOS and in-hospital costs for patients undergoing CTO PCI. Methods to identify high-risk patients and develop strategies to prevent complications may reduce CTO PCI costs.

RESUMO

BACKGROUND: Stroke is a serious complication after transcatheter aortic valve replacement (TAVR), yet predictive models are not available. A new risk model for in-hospital stroke after TAVR was developed and used to estimate site-specific performance. METHODS: We included 97,600 TAVR procedures from 521 sites in The Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry from July 2014 to June 2017. Association between baseline covariates and in-hospital stroke was estimated by logistic regression. Discrimination was evaluated by C-statistic. Calibration was tested internally via cross-validation. Hierarchical modeling was used to estimate risk-adjusted site-specific performance. RESULTS: Median age was 82 years, 44,926 (46.0%) were women, and 1,839 (1.9%) had in-hospital stroke. Covariates associated with stroke (odds ratio) included transapical access (1.44), access excluding transapical and transfemoral (1.77), prior stroke (1.57), prior transient ischemic attack (1.50), preprocedural shock, inotropes or mechanical assist device (1.48), smoking (1.28), porcelain aorta (1.23), peripheral arterial disease (1.21), age per 5 years (1.11), glomerular filtration rate per 5 mL/min (0.97), body surface area per m2 (0.55 male; 0.43 female), and prior aortic valve (0.78) and nonaortic valvular (0.42) procedures. The C-statistic was 0.622. Calibration curves demonstrated agreement between observed and expected stroke rates. Hierarchical modeling showed 10 (1.9%) centers with significantly higher odds ratios for in-hospital stroke than their peers. CONCLUSIONS: A risk model for in-hospital stroke after TAVR was developed from The Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry and used to estimate site-specific stroke performance. This model can serve as a valuable resource for quality improvement, clinical decision making, and patient counseling.

RESUMO

BACKGROUND: Readmissions within 30 days after acute myocardial infarction have been used as a performance metric for hospitals. However, evolving concepts of value-based reimbursement have shifted the focus to 90 days after hospital discharge. Tools are needed to determine risk for 90-day readmission to identify patients who might benefit from enhanced transitional healthcare resources. METHODS AND RESULTS: In this cohort study, we identified all Medicare beneficiaries with a primary diagnosis of acute myocardial infarction who were discharged from hospitals participating in National Cardiovascular Data Registry ACTION registry between 2008 and 2014. Among a random 70% sample (derivation cohort), we performed hierarchical proportional hazards regression, accounting for death as a competing risk, to assess predictors of all-cause readmission within 90 days. Models were validated in the remaining 30%. Among 86 849 unique patients, 23 912 (27.5%) were readmitted within 90 days. Of the readmissions, 55% occurred within 30 days and 81% occurred within 60 days. Predictors of readmission included older age and a history of diabetes mellitus or heart failure. Coronary revascularization was associated with a lower risk of readmission. A simple risk score incorporating patient demographic and clinical characteristics known before discharge identified groups of patients with readmission risks ranging from 13.1% to 42.9%. Model discrimination was moderate (C statistic=0.662), and calibration was excellent (slope=0.97, intercept=-0.04). CONCLUSIONS: Readmission within 90 days of hospitalization for acute myocardial infarction can be predicted by variables known before discharge and offers the potential to prospectively design transitional care to the risks of individual patients.

RESUMO

We examined the prevalence of cardio-renal-metabolic (CaReMe) conditions and their combinations among 530 747 adults with type 2 diabetes in a USA-based outpatient registry of 271 primary care, cardiology and endocrinology offices. We evaluated the following CaReMe conditions: hypertension, hyperlipidaemia, coronary artery disease (CAD), chronic kidney disease (CKD), cerebrovascular disease, peripheral artery disease, atrial fibrillation, heart failure, and gout or hyperuricaemia; prevalence estimates were adjusted based on the distribution of diabetes by age in the US population in 2015. We found that it was uncommon for patients to have isolated type 2 diabetes without other CaReMe conditions, with only 6.4% having no other CaReMe conditions and 51% having ≥3 other CaReMe conditions. The most prevalent individual conditions were hypertension (83%), hyperlipidemia (81%), CAD (32%) and CKD (20%), and the most common combinations included various groupings of hypertension, hyperlipidaemia, atherosclerotic cardiovascular disease and CKD. Older age, male sex and tobacco use were each associated with increased numbers of CaReMe conditions. These findings highlight the clinical need for novel treatment strategies for diabetes that address both glycaemia and coexisting disease states.

RESUMO

OBJECTIVES: The aim of this study was to develop and validate a risk adjustment model for 30-day mortality after transcatheter aortic valve replacement (TAVR) that accounted for both standard clinical factors and pre-procedural health status and frailty. BACKGROUND: Assessment of risk for TAVR is important both for patient selection and provider comparisons. Prior efforts for risk adjustment have focused on in-hospital mortality, which is easily obtainable but can be biased because of early discharge of ill patients. METHODS: Using data from patients who underwent TAVR as part of the Society of Thoracic Surgeons/American College of Cardiology TVT (Transcatheter Valve Therapy) Registry (June 2013 to May 2016), a hierarchical logistic regression model to estimate risk for 30-day mortality after TAVR based only on pre-procedural factors and access site was developed and internally validated. The model included factors from the original TVT Registry in-hospital mortality model but added the Kansas City Cardiomyopathy Questionnaire (health status) and gait speed (5-m walk test). RESULTS: Among 21,661 TAVR patients at 188 sites, 1,025 (4.7%) died within 30 days. Independent predictors of 30-day death included older age, low body weight, worse renal function, peripheral artery disease, home oxygen, prior myocardial infarction, left main coronary artery disease, tricuspid regurgitation, nonfemoral access, worse baseline health status, and inability to walk. The predicted 30-day mortality risk ranged from 1.1% (lowest decile of risk) to 13.8% (highest decile of risk). The model was able to stratify risk on the basis of patient factors with good discrimination (C = 0.71 [derivation], C = 0.70 [split-sample validation]) and excellent calibration, both overall and in key patient subgroups. CONCLUSIONS: A clinical risk model was developed for 30-day death after TAVR that included clinical data as well as health status and frailty. This model will facilitate tracking outcomes over time as TAVR expands to lower risk patients and to less experienced sites and will allow an objective comparison of short-term mortality rates across centers.

RESUMO

Importance: Black patients experience worse outcomes than white patients following acute myocardial infarction (AMI). Objective: To examine the degree to which nonrace characteristics explain observed survival differences between white patients and black patients following AMI. Design, Setting, and Participants: This cohort study used the extensive socioeconomic and clinical characteristics from patients recovering from an AMI that were prospectively collected at 31 hospitals across the contiguous United States between 2003 and 2008 for the Prospective Registry Evaluating Myocardial Infarction: Events and Recovery registry and the Translational Research Investigating Underlying Disparities in Acute Myocardial Infarction Patients' Health Status registry. Survival was assessed using data from the National Death Index. Data were analyzed from December 2016 to July 2018. Main Outcomes and Measures: Patient characteristics were categorized into 8 domains, and the degree to which each domain discriminated self-identified black patients from white patients was determined by calculating propensity scores associated with black race for each domain as well as cumulatively across all domains. The final propensity score was associated with 1- and 5-year mortality rates. Results: Among 6402 patients (mean [SD] age, 60 [13] years; 2127 [33.2%] female; 1648 [25.7%] black individuals), the 5-year mortality rate following AMI was 28.9% (476 of 1648) for black patients and 18.0% (856 of 4754) for white patients (hazard ratio, 1.72; 95% CI, 1.54-1.92; P < .001). Most categories of patient characteristics differed substantially between black patients and white patients. The cumulative propensity score discriminated race, with a C statistic of 0.89, and the propensity scores were associated with 1- and 5-year mortality rates (hazard ratio for the 75th percentile of the propensity score vs 25th percentile, 1.72; 95% CI, 1.43-2.08; P < .001). Patients in the lowest propensity score quintile associated with being a black individual (regardless of whether they were of white or black race) had a 5-year mortality rate of 15.5%, while those in the highest quintile had a 5-year mortality rate of 31.0% (P < .001). After adjusting for the propensity associated with being a black patient, there was no significant mortality rate difference by race (adjusted hazard ratio, 1.09; 95% CI, 0.93-1.26; P = .37) and no statistical interaction between race and propensity score (P = .42). Conclusions and Relevance: Characteristics of black patients and white patients differed significantly at the time of admission for AMI. Those characteristics were associated with an approximately 3-fold difference in 5-year mortality rate following AMI and mediated most of the observed mortality rate difference between the races.

RESUMO

BACKGROUND: Although guidelines and performance measures exist for patients with diabetes mellitus, achievement of these metrics is not well known. The Diabetes Collaborative Registry® (DCR) was formed to understand the quality of diabetes mellitus care across the primary and specialty care continuum in the United States. METHODS AND RESULTS: We assessed the frequency of achievement of 7 diabetes mellitus-related quality metrics and variability across the Diabetes Collaborative Registry® sites. Among 574 972 patients with diabetes mellitus from 259 US practices, median (interquartile range) achievement of the quality metrics across the practices was the following: (1) glycemic control: 19% (5-47); (2) blood pressure control: 80% (67-88); (3) angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers in patients with coronary artery disease: 62% (51-69); (4) nephropathy screening: 62% (53-71); (5) eye examination: 0.7% (0.0-79); (6) foot examination: 0.0% (0.0-2.3); and (7) tobacco screening/cessation counseling: 86% (80-94). In hierarchical, modified Poisson regression models, there was substantial variability in meeting these metrics across sites, particularly with documentation of glycemic control and eye and foot examinations. There was also notable variation across specialties, with endocrinology practices performing better on glycemic control and diabetes mellitus foot examinations and cardiology practices succeeding more in blood pressure control and use of angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers. CONCLUSIONS: The Diabetes Collaborative Registry® was established to document and improve the quality of outpatient diabetes mellitus care. While target achievement of some metrics of cardiovascular risk modification was high, achievement of others was suboptimal and highly variable. This may be attributable to fragmentation of care, lack of ownership among various specialists concerning certain domains of care, incomplete documentation, true gaps in care, or a combination of these factors.

RESUMO

Importance: In patients with severe aortic stenosis (AS) at intermediate surgical risk, treatment with transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) results in similar 2-year survival. The effect of TAVR vs SAVR on health status in patients at intermediate surgical risk is unknown. Objective: To compare health-related quality of life among intermediate-risk patients with severe AS treated with either TAVR or SAVR. Design, Setting, and Participants: Between December 2011 and November 2013, 2032 intermediate-risk patients with severe AS were randomized to TAVR with the Sapien XT valve or SAVR in the Placement of Aortic Transcatheter Valve 2 Trial and were followed up for 2 years. Data analysis was conducted between March 1, 2016, to April 30, 2017. Main Outcomes and Measures: Health status was assessed at baseline, 1 month, 1 year, and 2 years using the Kansas City Cardiomyopathy Questionnaire (KCCQ) (23 items covering physical function, social function, symptoms, self-efficacy and knowledge, and quality of life on a 0- to 100-point scale; higher scores indicate better quality of life), Medical Outcomes Study Short Form-36 (36 items covering 8 dimensions of health status as well as physical and mental summary scores; higher scores represent better health status), and EuroQOL-5D (assesses 5 dimensions of general health on a 3-level scale, with utility scores ranging from 0 [death] to 1 [ideal health]). Analysis of covariance was used to examine changes in health status over time, adjusting for baseline status. Results: Of the 2032 randomized patients, baseline health status was available for 1833 individuals (950 TAVR, 883 SAVR) who formed the primary analytic cohort. A total of 1006 (54.9%) of the population were men; mean (SD) age was 81.4 (6.8) years. Over 2 years, both TAVR and SAVR were associated with significant improvements in both disease specific (16-22 points on the KCCQ-OS scale) and generic health status (3.9-5.1 points on the SF-36 physical summary scale). At 1 month, TAVR was associated with better health status than SAVR, but this difference was restricted to patients treated via transfemoral access (mean difference in the KCCQ overall summary [KCCQ-OS] score, 14.1 points; 95% CI, 11.7 to 16.4; P < .01) and was not seen in patients treated via transthoracic access (mean difference in KCCQ-OS, 3.5 points; 95% CI, -1.4 to 8.4; P < .01 for interaction). There were no significant differences between TAVR and SAVR in any health status measures at 1 or 2 years. Conclusions and Relevance: Among intermediate-risk patients with severe AS, health status improved significantly with both TAVR and SAVR through 2 years of follow up. Early health status improvement was greater with TAVR, but only among patients treated via transfemoral access. Longer term follow-up is needed to assess the durability of quality-of-life improvement with TAVR vs SAVR in this population. Trial Registration: clinicaltrials.gov Identifier: NCT01314313.

RESUMO

OBJECTIVES: To assess patients' perspective about factors associated with stent choice. BACKGROUND: Drug eluting stents (DES) markedly reduce the risk of repeat percutaneous coronary intervention (PCI), but necessitate a longer duration of dual anti-platelet therapy (DAPT) as compared with bare metal stents (BMS). Thus, understanding patients' perspective about factors associated with stent choice is paramount. METHODS: Patients undergoing angiography rated, on a 10-point scale, the importance (1 = not important, 10 = most important) of avoiding repeat revascularization and avoiding the following potential DAPT drawbacks: bleeding/bruising, more pills/day, medication costs and delaying elective surgery. The factor, or group of factors, that was rated highest by each patient was identified. RESULTS: Among 311 patients, repeat revascularization was the single most important consideration to 14.4% of patients, while 20.6% considered avoiding one of the DAPT drawbacks as most important. Most patients (65%) considered avoiding at least one DAPT drawback as important as avoiding repeat revascularization. In no subgroup of patients did more than a quarter of patients prefer avoiding repeat revascularization above all other concerns. Among patients undergoing PCI, more than three quarters received a DES, regardless of their stated preferences (DES use among those most valuing DES benefits, avoiding DAPT drawbacks, or both equally were 78.7%, 86.2%, and 85.6%, respectively, P = 0.56). CONCLUSION: Most patients reported that avoiding DAPT drawbacks was as important as avoiding repeat revascularization. Eliciting patient preferences regarding stent type can enhance shared decision-making and allow physicians to better tailor stent choice to patients' goals and values.

RESUMO

Although eliminating angina is a primary goal in treating patients with chronic coronary artery disease (CAD), few contemporary data quantify prevalence and severity of angina across US cardiology practices. The authors hypothesized that angina among outpatients with CAD managed by US cardiologists is low and its prevalence varies by site. Among 25 US outpatient cardiology clinics enrolled in the American College of Cardiology Practice Innovation and Clinical Excellence (PINNACLE) registry, we prospectively recruited a consecutive sample of patients with chronic CAD over a 1- to 2-week period at each site between April 2013 and July 2015, irrespective of the reason for their appointment. Eligible patients had documented history of CAD (prior acute coronary syndrome, prior coronary revascularization procedure, or diagnosis of stable angina) and ≥1 prior office visit at the practice site. Angina was assessed directly from patients using the Seattle Angina Questionnaire Angina Frequency score. Among 1257 patients from 25 sites, 7.6% (n = 96) reported daily/weekly, 25.1% (n = 315) monthly, and 67.3% (n = 846) no angina. The proportion of patients with daily/weekly angina at each site ranged from 2.0% to 24.0%, but just over half (56.3%) were on ≥2 antianginal medications, with wide variability across sites (0%-100%). One-third of outpatients with chronic CAD managed by cardiologists report having angina in the prior month, and 7.6% have frequent symptoms. Among those with frequent angina, just over half were on ≥2 antianginal medications, with wide variability across sites. These findings suggest an opportunity to improve symptom control.

RESUMO

OBJECTIVES: To determine the prognostic value of slow gait in predicting outcomes 1 year after acute myocardial infarction (AMI). DESIGN: Observational cohort with longitudinal follow-up. SETTING: Twenty-four U.S. hospitals participating in the Translational Research Investigating Underlying disparities in recovery from acute Myocardial infarction: Patients' Health status Registry. PARTICIPANTS: Older adults (≥65) with in-home gait assessment 1 month after AMI (N = 338). MEASUREMENTS: Baseline characteristics and 1-year mortality or hospital readmission adjusted using Cox proportional hazards regression in older adults with slow (<0.8 m/s) versus preserved (≥0.8 m/s) gait speed. RESULTS: Slow gait was present in 181 participants (53.6%). Those with slow gait were older, more likely to be female and nonwhite, and had a higher prevalence of heart failure and diabetes mellitus. They were also more likely to die or be readmitted to the hospital within 1 year than those with preserved gait (35.4% vs 18.5%, log-rank P = .006). This association remained significant after adjusting for age, sex, and race (slow vs preserved gait hazard ratio (HR) = 1.76, 95% confidence interval (CI)=1.08-2.87, P = .02) but was no longer significant after adding clinical factors (HR = 1.23, 95% CI=0.74-2.04, P = .43). CONCLUSION: Slow gait, a marker of frailty, is common 1 month after AMI in older adults and is associated with nearly twice the risk of dying or hospital readmission at 1 year. Understanding its prognostic importance independent of comorbidities and whether routine testing of gait speed can improve care requires further investigation.

RESUMO

BACKGROUND: Previous studies of the cost-effectiveness of transcatheter aortic valve replacement (TAVR) have been based primarily on a single balloon-expandable system. OBJECTIVES: The goal of this study was to evaluate the cost-effectiveness of TAVR with a self-expanding prosthesis compared with surgical aortic valve replacement (SAVR) for patients with severe aortic stenosis and high surgical risk. METHODS: We performed a formal economic analysis on the basis of individual, patient-level data from the CoreValve U.S. High Risk Pivotal Trial. Empirical data regarding survival and quality of life over 2 years, and medical resource use and hospital costs through 12 months were used to project life expectancy, quality-adjusted life expectancy, and lifetime medical costs in order to estimate the incremental cost-effectiveness of TAVR versus SAVR from a U.S. RESULTS: Relative to SAVR, TAVR reduced initial length of stay an average of 4.4 days, decreased the need for rehabilitation services at discharge, and resulted in superior 1-month quality of life. Index admission and projected lifetime costs were higher with TAVR than with SAVR (differences $11,260 and $17,849 per patient, respectively), whereas TAVR was projected to provide a lifetime gain of 0.32 quality-adjusted life-years ([QALY]; 0.41 LY) with 3% discounting. Lifetime incremental cost-effectiveness ratios were $55,090 per QALY gained and $43,114 per LY gained. Sensitivity analyses indicated that a reduction in the initial cost of TAVR by ∼$1,650 would lead to an incremental cost-effectiveness ratio <$50,000/QALY gained. CONCLUSIONS: In a high-risk clinical trial population, TAVR with a self-expanding prosthesis provided meaningful clinical benefits compared with SAVR, with incremental costs considered acceptable by current U.S. STANDARDS: With expected modest reductions in the cost of index TAVR admissions, the value of TAVR compared with SAVR in this patient population would become high.

RESUMO

BACKGROUND: In patients with severe aortic stenosis, transcatheter aortic valve replacement (TAVR) improves survival when compared with nonsurgical therapy but with higher in-hospital and lifetime costs. Complications associated with TAVR may decrease with greater experience and improved devices, thereby reducing the overall cost of the procedure. Therefore, we sought to estimate the effect of periprocedural complications on in-hospital costs and length of stay of TAVR. METHODS AND RESULTS: Using detailed cost data from 406 TAVR patients enrolled in the Placement of Aortic Transcatheter Valve (PARTNER) I trial, we developed multivariable models to estimate the incremental cost and length of stay associated with specific periprocedural complications. Attributable costs and length of stay for each complication were calculated by multiplying the independent cost of each event by its frequency in the treatment group. Mean cost for the initial hospitalization was $79 619±40 570 ($50 891 excluding the valve); 49% of patients had ≥1 complication. Seven complications were independently associated with increased hospital costs, with major bleeding, arrhythmia, and death accounting for the largest attributable cost per patient. Renal failure and the need for repeat TAVR, although less frequent, were also associated with substantial incremental and attributable costs. Overall, complications accounted for $12 475 per patient in initial hospital costs and 2.4 days of hospitalization. CONCLUSIONS: In the PARTNER trial, periprocedural complications were frequent, costly, and accounted for ≈25% of non-implant-related hospital costs. Avoidance of complications should improve the cost-effectiveness of TAVR for inoperable and high-risk patients, but reductions in the cost of uncomplicated TAVR will also be necessary for optimal efficiency.
