Cardiac rehabilitation availability and characteristics in Latin America and the Caribbean: A Global Comparison.

BACKGROUND: This study aimed to establish availability and characteristics of cardiac rehabilitation (CR) in Latin America and the Caribbean (LAC), where cardiovascular disease is highly prevalent. METHODS: In this cross-sectional sub-analysis focusing on the 35 LAC countries, local cardiovascular societies identified CR programs globally. An online survey was administered to identified programs, assessing capacity and characteristics. CR need was computed relative to ischemic heart disease (IHD) incidence from the Global Burden of Disease study. RESULTS: ≥1 CR program was identified in 24 LAC countries (68.5% availability; median = 3 programs/country). Data were collected in 20/24 countries (83.3%); 139/255 programs responded (54.5%), and compared to responses from 1082 programs in 111 countries. LAC density was 1 CR spot per 24 IHD patients/year (vs 18 globally). Greatest need was observed in Brazil, Dominican Republic and Mexico (all with >150,000 spots needed/year). In 62.8% (vs 37.2% globally P < .001) of CR programs, patients pay out-of-pocket for some or all of CR. CR teams were comprised of a mean of 5.0 ± 2.3 staff (vs 6.0 ± 2.8 globally; P < .001); Social workers, dietitians, kinesiologists, and nurses were significantly less common on CR teams than globally. Median number of core components offered was 8 (vs 9 globally; P < .001). Median dose of CR was 36 sessions (vs 24 globally; P < .001). Only 27 (20.9%) programs offered alternative CR models (vs 31.1% globally; P < .01). CONCLUSION: In LAC countries, there is very limited CR capacity in relation to need. CR dose is high, but comprehensiveness low, which could be rectified with a more multidisciplinary team.

SARS-CoV 2 Infection (Covid-19) and Cardiovascular Disease in Africa: Health Care and Socio-Economic Implications.

The current pandemic of SARS-COV 2 infection (Covid-19) is challenging health systems and communities worldwide. At the individual level, the main biological system involved in Covid-19 is the respiratory system. Respiratory complications range from mild flu-like illness symptoms to a fatal respiratory distress syndrome or a severe and fulminant pneumonia. Critically, the presence of a pre-existing cardiovascular disease or its risk factors, such as hypertension or type II diabetes mellitus, increases the chance of having severe complications (including death) if infected by the virus. In addition, the infection can worsen an existing cardiovascular disease or precipitate new ones. This paper presents a contemporary review of cardiovascular complications of Covid-19. It also specifically examines the impact of the disease on those already vulnerable and on the poorly resourced health systems of Africa as well as the potential broader consequences on the socio-economic health of this region.

Efficacy and cost-effectiveness of a therapist-assisted web-based intervention for depression and anxiety in patients with ischemic heart disease attending cardiac rehabilitation [eMindYourHeart trial]: a randomised controlled trial protocol.

BACKGROUND: One in five patients with ischaemic heart disease (IHD) develop comorbid depression or anxiety. Depression is associated with risk of non-adherence to cardiac rehabilitation (CR) and dropout, inadequate risk factor management, poor quality of life (QoL), increased healthcare costs and premature death. In 2020, IHD and depression are expected to be among the top contributors to the disease-burden worldwide. Hence, it is paramount to treat both the underlying somatic disease as well as depression and anxiety. eMindYourHeart will evaluate the efficacy and cost-effectiveness of a therapist-assisted eHealth intervention targeting depression and anxiety in patients with IHD, which may help fill this gap in clinical care. METHODS: eMindYourHeart is a multi-center, two-armed, unblinded randomised controlled trial that will compare a therapist-assisted eHealth intervention to treatment as usual in 188 CR patients with IHD and comorbid depression or anxiety. The primary outcome of the trial is symptoms of depression, measured with the Hospital Anxiety and Depression Scale (HADS) at 3 months. Secondary outcomes evaluated at 3, 6, and 12 months include symptoms of depression and anxiety (HADS), perceived stress, health complaints, QoL (HeartQoL), trial dropout (number of patients dropped out in either arm at 3 months) and cost-effectiveness. DISCUSSION: To our knowledge, this is the first trial to evaluate both the efficacy and cost-effectiveness of a therapist-assisted eHealth intervention in patients with IHD and comorbid psychological distress as part of CR. Integrating screening for and treatment of depression and anxiety into standard CR may decrease dropout and facilitate better risk factor management, as it is presented as "one package" to patients, and they can access the eMindYourHeart program in their own time and at their own convenience. The trial holds a strong potential for improving the quality of care for an increasing population of patients with IHD and comorbid depression, anxiety or both, with likely benefits to patients, families, and society at large due to potential reductions in direct and indirect costs, if proven successful. Trial registration The trial was prospectively registered on https://clinicaltrials.gov/ct2/show/NCT04172974 on November 21, 2019 with registration number [NCT04172974].

Cost-effectiveness of ablation of ventricular tachycardia in ischaemic cardiomyopathy: limitations in the trial evidence base.

Objective: Catheter ablation is an important treatment for ventricular tachycardia (VT) that reduces the frequency of episodes of VT. We sought to evaluate the cost-effectiveness of catheter ablation versus antiarrhythmic drug (AAD) therapy. Methods: A decision-analytic Markov model was used to calculate the costs and health outcomes of catheter ablation or AAD treatment of VT for a hypothetical cohort of patients with ischaemic cardiomyopathy and an implantable cardioverter-defibrillator. The health states and input parameters of the model were informed by patient-reported health-related quality of life (HRQL) data using randomised clinical trial (RCT)-level evidence wherever possible. Costs were calculated from a 2018 UK perspective. Results: Catheter ablation versus AAD therapy had an incremental cost-effectiveness ratio (ICER) of £144 150 (€161 448) per quality-adjusted life-year gained, over a 5-year time horizon. This ICER was driven by small differences in patient-reported HRQL between AAD therapy and catheter ablation. However, only three of six RCTs had measured patient-reported HRQL, and when this was done, it was assessed infrequently. Using probabilistic sensitivity analyses, the likelihood of catheter ablation being cost-effective was only 11%, assuming a willingness-to-pay threshold of £30 000 used by the UK's National Institute for Health and Care Excellence. Conclusion: Catheter ablation of VT is unlikely to be cost-effective compared with AAD therapy based on the current randomised trial evidence. However, better designed studies incorporating detailed and more frequent quality of life assessments are needed to provide more robust and informed cost-effectiveness analyses.

High-Need Phenotypes in Medicare Beneficiaries: Drivers of Variation in Utilization and Outcomes.

OBJECTIVES: High-need (HN) Medicare beneficiaries heavily use healthcare services at a high cost. This population is heterogeneous, composed of individuals with varying degrees of medical complexity and healthcare needs. To improve healthcare delivery and decrease costs, it is critical to identify the subpopulations present within this population. We aimed to (1) identify distinct clinical phenotypes present within HN Medicare beneficiaries, and (2) examine differences in outcomes between phenotypes. DESIGN: Latent class analysis was used to identify phenotypes within a sample of HN fee-for-service (FFS) Medicare beneficiaries aged 65 years and older using Medicare claims and post-acute assessment data. SETTING: Not applicable. PARTICIPANTS: Two cross-sectional cohorts were used to identify phenotypes. Cohorts included FFS Medicare beneficiaries aged 65 and older who survived through 2014 (n = 415 659) and 2015 (n = 416 643). MEASUREMENTS: The following variables were used to identify phenotypes: acute and post-acute care use, functional dependency in one or more activities of daily living, presence of six or more chronic conditions, and complex chronic conditions. Mortality, hospitalizations, healthcare expenditures, and days in the community were compared between phenotypes. RESULTS: Five phenotypes were identified: (1) comorbid ischemic heart disease with hospitalization and skilled nursing facility use (22% of the HN sample), (2) comorbid ischemic heart disease with home care use (23%), (3) home care use (12%), (4) high comorbidity with hospitalization (32%), and (5) Alzheimer's disease/related dementias with functional dependency and nursing home use (11%). Mortality was highest in phenotypes 1 and 2; hospitalizations and expenditures were highest in phenotypes 1, 3, and 4. CONCLUSIONS: Our findings represent a first step toward classifying the heterogeneity among HN Medicare beneficiaries. Further work is needed to identify modifiable utilization patterns between phenotypes to improve the value of healthcare provided to these subpopulations. J Am Geriatr Soc 68:70-77, 2019.

Incidence, Predictors, and Outcomes of Acute Ischemic Stroke Following Percutaneous Coronary Intervention.

OBJECTIVES: The aim of this study was to assess temporal trends in the incidence of ischemic stroke among patients undergoing percutaneous coronary intervention (PCI), predictors of post-PCI ischemic stroke, and the impact of post-PCI ischemic stroke on in-hospital morbidity, mortality, length of stay, and cost. BACKGROUND: Data on the incidence and outcomes of ischemic stroke in patients undergoing PCI in the contemporary era are limited. METHODS: The National Inpatient Sample was used to identify patients who underwent PCI between January 1, 2003, and December 31, 2016. The incidence of post-PCI ischemic stroke was calculated, and its predictors were assessed. In-hospital outcomes of patients with and those without post-PCI stroke were also compared. RESULTS: The adjusted incidence of post-PCI ischemic stroke increased during the study period from 0.6% to 0.96% following PCI for ST-segment elevation myocardial infarction, from 0.5% to 0.6% following PCI for non-ST-segment elevation myocardial infarction, and from 0.3% to 0.72% following PCI for unstable angina or stable ischemic disease (ptrend <0.001). Carotid disease, cardiogenic shock, atrial fibrillation, and older age were the strongest predictors of post-PCI ischemic stroke. Post-PCI stroke rates were lower at high-volume versus low- to intermediate-volume centers. Thrombolytics, cerebral angiography, and mechanical thrombectomy use increased over time but remained infrequent. After propensity score matching, in-hospital mortality was higher among patients with post-PCI stroke (23.5% vs. 11.0%, 9.5% vs. 2.8%, and 11.5% vs. 2.4% in the ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, and unstable angina or stable ischemic heart disease cohorts, respectively; p < 0.001). Post-PCI stroke was associated with a >2-fold increase in length of stay, a >3-fold increase in nonhome discharges, and a >60% increase in cost. CONCLUSIONS: The incidence of post-PCI ischemic stroke increased significantly over the past decade, partially because of the increasing complexity of patients undergoing PCI over time. Further studies are needed to systematically assess contributors to this worrisome trend and to identify effective strategies for its mitigation.

The indirect costs of ischemic heart disease through lost productive life years for Australia from 2015 to 2030: results from a microsimulation model.

BACKGROUND: Most studies measure the impact of ischemic heart disease (IHD) on individuals using quality of life metrics such as disability-adjusted life-years (DALYs); however, IHD also has an enormous impact on productive life years (PLYs). The objective of this study was to project the indirect costs of IHD resulting from lost PLYs to older Australian workers (45-64 years), government, and society 2015-2030. METHODS: Nationally representative data from the Surveys of Disability, Ageing and Carers (2003, 2009) were used to develop the base population in the microsimulation model (Health&WealthMOD2030), which integrated data from established microsimulation models (STINMOD, APPSIM), Treasury's population and workforce projections, and chronic conditions trends. RESULTS: We projected that 6700 people aged 45-64 were out of the labour force due to IHD in 2015, increasing to 8100 in 2030 (21 increase). National costs consisted of a loss of AU$273 (US$263) million in income for people with IHD in 2015, increasing to AU$443 ($US426) million (62% increase). For the government, extra welfare payments increased from AU$106 (US$102) million in 2015 to AU$143 (US$138) million in 2030 (35% increase); and lost income tax revenue increased from AU$74 (US$71) million in 2015 to AU$117 (US$113) million in 2030 (58% increase). A loss of AU$785 (US$755) million in GDP was projected for 2015, increasing to AU$1125 (US$1082) million in 2030. CONCLUSIONS: Significant costs of IHD through lost productivity are incurred by individuals, the government, and society. The benefits of IHD interventions include not only improved health but also potentially economic benefits as workforce capacity.

Burden of Disease Attributable to Obesity and Overweight in Colombia.

OBJECTIVES: To estimate the burden of disease attributable to obesity and overweight conditions using disability-adjusted life-years (DALYs) in Colombia. METHODS: The burden of disease was estimated following an adapted methodology published by the World Health Organization. A selection of diseases was performed in which overweight and obesity are risk factors. DALYs were calculated by obtaining the proportion of cases and deaths of every disease that can be attributable to obesity and overweight conditions. The economic impact of obesity was calculated by multiplying the cost of care per patient for each comorbidity by the number of cases attributable exclusively to obesity. RESULTS: A total of 997 371 DALYs were estimated, 45% of which corresponded to men; 81% of DALYs corresponded to years lived with disability. Conditions with greater attributable DALYs are, in order, hypertension (31.6% of the total DALYs), type 2 diabetes mellitus (28.0%), cardiac ischemic disease (14.6%), and lower back pain (11.2%). An estimation of 20.5 DALYs per 1000 inhabitants was made. The economic impact of care for comorbidities associated with obesity could amount to $2158 million. CONCLUSIONS: Obesity and overweight conditions are related to higher mortality and disability than previously estimated; effective interventions aimed at prevention and treatment will have a high impact on quality of life.

Revascularization Rates and Associated Costs in Patients With Stable Ischemic Heart Disease Initiating Ranolazine Versus Traditional Antianginals as Add-on Therapy.

To assess the frequency and costs of revascularization procedures in patients with stable ischemic heart disease (SIHD) initiating ranolazine versus traditional antianginals. Adults (≥18 years) with a diagnosis of SIHD who initiated ranolazine or a traditional antianginal (beta-blocker [BB], calcium channel blocker [CCB], or long-acting nitrate [LAN]) as second or third line therapy between 2008 and 2016, were selected from the IBM MarketScan Databases. Inverse probability weighting based on propensity score was employed to balance the ranolazine and traditional antianginals cohorts on patient clinical characteristics. Outcomes assessed were frequency and total cost of revascularization procedures over a 12-month follow-up. A total of 108,741 patients with SIHD were included. Of these, 18% initiated treatment with ranolazine, 21% received BBs, 24% received CCBs, and 37% were treated with LANs. Revascularization rates were significantly lower in ranolazine patients (11%) than in BB (16%) and LAN (14%) patients (both p <0.001), and more comparable to CCB patients (10%; p = 0.007). Compared with BB and LAN, those in the ranolazine cohort were less likely to have a revascularization procedure during hospitalization and had a shorter length of stay if hospitalized (all p <0.001). The mean healthcare costs associated with revascularization were lower in ranolazine patients ($2,933) than in BB ($4,465) and LAN ($3,609) patients (p <0.001), but similar to CCB patients ($2,753; p = 0.29). In conclusion, ranolazine treatment in patients with SIHD was associated with fewer revascularization procedures and lower associated healthcare costs compared with patients initiating BB or LAN, and comparable to patients initiating CCBs.

PET-Based Imaging of Ischemic Heart Disease.

PET-based cardiac nuclear imaging plays a large role in the management of ischemic heart disease. Compared with conventional single-photon emission CT myocardial perfusion imaging, PET provides superior accuracy in diagnosis of coronary artery disease and, with the incorporation of myocardial blood flow and coronary flow reserve, adds value in assessing prognosis for established coronary and microvascular disease. This review describes these and other uses of PET in ischemic heart disease, including assessing myocardial viability in ischemic cardiomyopathy. Developments in novel PET flow tracers and molecular imaging tools to assess atherosclerotic plaque vulnerability, vascular calcification, and vascular remodeling also are described.

Tailoring Antiplatelet Therapy Intensity to Ischemic and Bleeding Risk.

BACKGROUND: Balancing ischemic and bleeding risk is an evolving framework. METHODS AND RESULTS: Our objectives were to simulate changes in risks for adverse events and event-driven costs with use of ticagrelor or prasugrel versus clopidogrel according to varying levels of ischemic and bleeding risk. Using the validated PARIS risk functions, we estimated 1-year ischemic (myocardial infarction or stent thrombosis) and bleeding (Bleeding Academic Research Consortium types 3 or 5) event rates among PARIS study participants who underwent percutaneous coronary intervention with drug-eluting stent implantation for an acute coronary syndrome and were discharged with aspirin and clopidogrel (n=1497). Simulated changes in adverse events with ticagrelor or prasugrel were calculated by applying treatment effects from randomized trials for a 1-year time horizon. Event costs were estimated using National Inpatient Sample data. Net costs were calculated between antiplatelet therapy groups according to level of ischemic and bleeding risk. After weighting events for quality-of-life impact, we calculated event rates and costs for risk-tailored treatment versus clopidogrel under multiple drug pricing assumptions. One-year rates (per 1000 person-years) for ischemic events were 12.6, 24.1, and 66.1, respectively, among those at low (n=630), intermediate (n=536), and high (n=331) ischemic risk. Analogous bleeding rates were 11.0, 23.9, and 66.2, respectively, among low (n=728), intermediate (n=634), and high (n=135) bleeding risk patients. Mean per event costs were $22 174 (ischemic) and $12 203 (bleeding). When risks for ischemia matched or exceeded bleeding, simulated utility-weighted event rates favored ticagrelor/prasugrel, whereas clopidogrel reduced utility-weighted events when bleeding exceeded ischemic risk. One-year costs were sensitive to drug pricing assumptions, and risk-tailored treatment with either agent progressed from cost incurring to cost saving with increasing generic market share. CONCLUSIONS: Tailoring antiplatelet therapy intensity to patient risk may improve health utility and could produce cost savings in the first year after percutaneous coronary intervention.

Incidence and outcomes of early percutaneous coronary intervention after isolated valve surgery.

BACKGROUND: Coronary ischemia requiring early percutaneous coronary intervention (PCI) is a rare but serious complication of isolated valve surgery. We sought of assess the incidence, predictors and outcomes of early PCI after isolated valve surgery using the national inpatient sample. METHODS: Patients who underwent isolated aortic valve replacement (AVR), isolated mitral valve repair (MVr) or replacement (MVR) between 2003 and 2014 were identified. Patients who had early postoperative PCI were compared with patients who did not require PCI. Primary end point was in-hospital mortality. Secondary endpoints were complications, length-of-stay and cost. RESULTS: Among the 135,611 included patients, 1,074 (0.8%) underwent PCI prior to discharge. Unadjusted in-hospital mortality was higher in patients requiring early PCI following AVR (11.2 vs. 3.1%), MVR (24.1 vs. 5.5%), and MVr (22.4 vs. 2.5%) (P < 0.001) compared with patients not requiring PCI. Postoperative PCI remained independently associated with higher mortality after adjusting for demographics, comorbidities and hospital characteristics (adjusted OR [aOR] = 3.74, 95%CI 2.70-5.17 for AVR, aOR = 6.10, 95%CI 4.53-8.23 for MVR, and aOR = 9.90, 95%CI 7.22-13.58 for MVr). Patients undergoing PCI had higher incidences of stroke, acute kidney injury, infectious complications, higher hospital charges, and longer hospitalizations. Age, robotic-assisted surgery, and chronic renal failure were independent predictors of needing early postoperative PCI. CONCLUSIONS: Early PCI after isolated aortic or mitral valve surgery is rare but is associated with substantial in-hospital morbidity, mortality, and cost. Further studies are needed to identify preventable causes, and optimal management strategies of this serious complication.

Quality of health economic evaluations for the ACC/AHA stable ischemic heart disease practice guideline: A systematic review.

BACKGROUND: The American College of Cardiology/American Heart Association (ACC/AHA) recently published a rigorous framework to guide integration of economic data into clinical guidelines. We assessed the quality of economic evaluations in a major ACC/AHA clinical guidance report. METHODS: We systematically identified cost-effectiveness analyses (CEAs) of RCTs cited in the ACC/AHA 2012 Guideline for the Diagnosis and Management of Patients with Stable Ischemic Heart Disease. We extracted: (1) study identifiers; (2) parent RCT information; (3) economic analysis characteristics; and (4) study quality using the Quality of Health Economic Studies instrument (QHES). RESULTS: Quality scores were categorized as high (≥75 points) or low (<75 points). Of 1,266 citations in the guideline, 219 were RCTs associated with 77 CEAs. Mean quality score was 81 (out of 100) and improved over time, though 29.9% of studies were low-quality. Cost-per-QALY was the most commonly reported primary outcome (39.0%). Low-quality studies were less likely to report study perspective, use appropriate time horizons, or address statistical and clinical uncertainty. Funding was overwhelmingly private (83%). A detailed methodological assessment of high-quality studies revealed domains of additional methodological issues not identified by the QHES. CONCLUSIONS: Economic evaluations of RCTs in the 2012 ACC/AHA ischemic heart disease guideline largely had high QHES scores but methodological issues existed among "high-quality" studies. Because the ACC/AHA has generally been more systematic in its integration of scientific evidence compared to other professional societies, it is likely that most societies will need to proceed more cautiously in their integration of economic evidence.

Medicare Accountable Care Organizations Are Not Associated With Reductions in the Use of Low-Value Coronary Revascularization.

BACKGROUND: Because specialty care accounts for half of Medicare expenditures, improving its value is critical to the success of Medicare accountable care organizations (ACOs) in curbing spending growth. However, whether ACOs have reduced low-value specialty care without compromising use of high-value services remains unknown. METHODS AND RESULTS: Using national Medicare data, we identified 2 cohorts: beneficiaries for whom the value of coronary revascularization is lower (those with ischemic heart disease without angina, congestive heart failure, or recent admission for acute myocardial infarction) and beneficiaries for whom its value is higher (those with recent acute myocardial infarction admission). We then determined the provider groups who cared for the cohorts, distinguishing between those participating (n=298) and those not participating in a Medicare ACO (1329). After measuring the provider groups' use of coronary artery bypass grafting and percutaneous coronary intervention among the 2 cohorts, we fit multivariable models to test the statistical significance of rates of change in low- and high-value revascularization after ACO participation. During the pre-ACO period, participating and nonparticipating provider groups had similar rates of low- and high-value revascularization. Our multivariable model results show that rates of change for low- and high-value coronary revascularization were not altered by a provider group's participation in a Medicare ACO (lower value: difference, -0.04 per year; 95% confidence interval, -0.11 to 0.03; higher value: difference, 0.96 per year; 95% confidence interval, -0.46 to 2.4). CONCLUSIONS: We found no association between provider group participation in a Medicare ACO and use of low- or high-value coronary revascularization.

Job Stress-attributable Burden of Disease in Korea.

BACKGROUND: As job stress is associated with various diseases and psychiatric conditions, we aimed to estimate the job stress-attributable burden of disease in Korea based on the concept of disability-adjusted life years (DALY). METHODS: We selected ischemic heart disease (IHD), stroke, major depressive disorder (MDD), and suicide as health outcomes from job stress, because of the ease of access to data estimating burdens and of important meaning of them in Korean occupational background. RESULTS: Our findings demonstrated that approximately 21% of Korean workers were exposed to high job strain, which was attributable for approximately 6.7% of IHDs, 6.9% of strokes, 13.6% of MDDs, and 4% of suicides. In terms of job stress-attributable DALY, the burdens of disease per 100,000 people were 38 for IHD, 72 for stroke, 168 for MDDs, and 44 for suicides. CONCLUSION: The present findings suggested that one-fifth of Korean workers were suffering from high job strain. Although the figures may not be accurate due to several assumptions, job stress is an important risk factor for health in working environment in Korea.

Cost of illness of ischemic heart disease in Japan: a time trend and future projections.

BACKGROUND: Ischemic heart disease (IHD/ICD10: I20-I25) is the second leading cause of deaths in Japan and accounts for 40% of deaths due to heart diseases. This study aimed to calculate the economic burden of IHD using the cost of illness (COI) method and to identify key factors that drive the change of the economic burden of IHD. METHODS: We calculated the cost of illness (COI) every 3 years from 1996 to 2014 using governmental statistics. We then predicted the COI for every 3 years starting from 2017 up to 2029 using the fixed and variable model estimations. Only the estimated future population was used as a variable in the fixed model estimation. By contrast, variable model estimation considered the time trend of health-related indicators over the past 18 years. We derived the COI from the sum of direct and indirect costs (morbidity and mortality). RESULTS: The past estimation of COI slightly increased from 1493.8 billion yen in 1996 to 1708.3 billion yen in 2014. Future forecasts indicated that it would decrease from 1619.0 billion yen in 2017 to 1220.5 billion yen in 2029. CONCLUSION: The past estimation showed that the COI of IHD increased; in the mixed model, the COI was predicted to decrease with the continuing trend of health-related indicators. The COI of IHD in the future projection showed that, although the average age of death increased by social aging, the influence of the number of deaths and mortality cost decreased.

Troponin T monitoring to detect myocardial injury after noncardiac surgery: a cost-consequence analysis.

BACKGROUND: Myocardial injury after noncardiac surgery (MINS) is a mostly asymptomatic condition that is strongly associated with 30-day mortality; however, it remains mostly undetected without systematic troponin T monitoring. We evaluated the cost and consequences of postoperative troponin T monitoring to detect MINS. METHODS: We conducted a model-based cost-consequence analysis to compare the impact of routine troponin T monitoring versus standard care (troponin T measurement triggered by ischemic symptoms) on the incidence of MINS detection. Model inputs were based on Canadian patients enrolled in the Vascular Events in Noncardiac Surgery Patients Cohort Evaluation (VISION) study, which enrolled patients aged 45 years or older undergoing inpatient noncardiac surgery. We conducted probability analyses with 10 000 iterations and extensive sensitivity analyses. RESULTS: The data were based on 6021 patients (48% men, mean age 65 [standard deviation 12] yr). The 30-day mortality rate for MINS was 9.6%. We determined the incremental cost to avoid missing a MINS event as $1632 (2015 Canadian dollars). The cost-effectiveness of troponin monitoring was higher in patient subgroups at higher risk for MINS, e.g., those aged 65 years or more, or with a history of atherosclerosis or diabetes ($1309). CONCLUSION: The costs associated with a troponin T monitoring program to detect MINS were moderate. Based on the estimated incremental cost per health gain, implementation of postoperative troponin T monitoring seems appealing, particularly in patients at high risk for MINS.

CONTEXTE: Les lésions myocardiques après chirurgie non cardiaque (CNC) sont majoritairement asymptomatiques et fortement associées au risque de mortalité dans les 30 jours; toutefois, dans la plupart des cas, elles ne sont pas détectées en l'absence d'une surveillance systématique de la troponine T. Nous avons évalué les coûts et les conséquences d'une telle surveillance pour détecter les lésions myocardiques après CNC. MÉTHODES: Nous avons mené une analyse coût-conséquence modélisée pour comparer la surveillance systématique de la troponine T aux soins habituels seuls (mesure de la troponine T seulement s'il y a présence de symptômes d'ischémie) sur la fréquence de détection de lésions myocardiques après CNC. Les données ayant servi à l'analyse provenaient des patients canadiens ayant participé à l'étude de cohorte VISION, qui visait à évaluer les complications vasculaires chez les patients de 45 ans et plus ayant subi une CNC. Nous avons mené des analyses de probabilité avec 10  000 itérations et des analyses de sensibilité approfondies. RÉSULTATS: Les données portaient sur 6021 patients (48 % du sexe masculin; âge moyen de 65 ans [écart-type de 12 ans]). Le taux de mortalité dans les 30 jours associé à une lésion myocardique après CNC était de 9,6 %. Nous avons déterminé que le coût marginal de la détection de la présence d'une lésion par surveillance de la troponine T était de 1632 $ (dollars canadiens en 2015). Le rapport coût-efficacité était plus bas pour les sous-groupes de patients à risque élevé de lésion myocardique après CNC, comme les patients de 65 ans et plus ou ceux ayant des antécédents d'athérosclérose ou de diabète (1309 $), que pour leurs pairs. CONCLUSION: Les coûts associés à un programme de surveillance de la troponine T pour détecter les lésions myocardiques après CNC étaient modérés. Le coût marginal estimé par gain de santé indique que la mise en œuvre de ce type de programme pourrait être une option intéressante, surtout pour les patients à risque élevé de lésion myocardique après CNC.

Estimates of Medication Expenditure for Ischemic Heart Disease Accompanying Chronic Obstructive Pulmonary Disease.

Ischemic heart disease (IHD) is a frequent accompaniment of chronic obstructive pulmonary disease (COPD). Co-occurrence of these two diseases is associated with many risk factors, difficulties in implementing appropriate therapies, numerous complications, and high spending for treatment. All these elements significantly reduce the quality of life of patients. The aim of this study was to estimate the expenditure for medications involved with IHD pharmacotherapy in the course of COPD. This retrospective study was based on the review of medical files of 57 patients, 27 women and 30 men, diagnosed with IHD, according to the severity classification, in the course of COPD which was staged according to the GOLD criteria. We found a considerable increase in per capita per year retail spending for drugs. The spending increased with the severity class of IHD; from 27.41 EUR in Class I to 142.30 EUR in Class IV. This spending did not include the treatment cost for the basic disease, i.e., COPD. A high individual cost burden was decreased by a discounting intervention of the National Health Fund. Despite a relatively high drug expenditure, we consider the treatment being cost-effective since we noticed a reduction in the classical risk factors for IHD, related to metabolic disturbances and lifestyle features, as soon as 2 months after treatment initiation. This study confirms that heart disease accompanying COPD is a frequent occurrence, generating high costs of treatment, which relates to the severity of this comorbidity.

Burden of 30-Day Readmissions After Percutaneous Coronary Intervention in 833,344 Patients in the United States: Predictors, Causes, and Cost: Insights From the Nationwide Readmission Database.

OBJECTIVES: This study aimed to examine the 30-day unplanned readmissions rate, predictors of readmission, causes of readmissions, and clinical impact of readmissions after percutaneous coronary intervention (PCI). BACKGROUND: Unplanned rehospitalizations following PCI carry significant burden to both patients and the local health care economy and are increasingly considered as an indicator of quality of care. METHODS: Patients undergoing PCI between 2013 and 2014 in the U.S. Nationwide Readmission Database were included. Incidence, predictors, causes, and cost of 30-day unplanned readmissions were determined. RESULTS: A total of 833,344 patients with PCI were included, of whom 77,982 (9.3%) had an unplanned readmission within 30 days. Length of stay for the index PCI was greater (4.7 vs. 3.9 days) and mean total hospital cost ($23,211 vs. $37,524) was higher for patients who were readmitted compared with those not readmitted. The factors strongly independently associated with readmissions were index hospitalization discharge against medical advice (odds ratio [OR]: 1.91; 95% confidence interval [CI]: 1.65 to 2.22), transfer to short-term hospital for inpatient care (OR: 1.62; 95% CI: 1.38 to 1.90), discharge to care home (OR: 1.57; 95% CI: 1.51 to 1.64), and chronic kidney disease (OR: 1.50; 95% CI: 1.44 to 1.55). Charlson Comorbidity Index score (OR: 1.28; 95% CI: 1.27 to 1.29) and number of comorbidities (OR: 1.18; 95% CI: 1.17 to 1.18) were independently associated with unplanned readmission. The majority of readmissions were due to noncardiac causes (56.1%). CONCLUSIONS: Thirty-day readmissions after PCI are relatively common and relate to baseline comorbidities and place of discharge. More than one-half of the readmissions were due to noncardiac causes.

Risk of Ischemic Heart Disease in Patients With Sjögren's Syndrome.

BACKGROUND: Ischemic heart disease (IHD) has emerged as a major cause of morbidity and mortality in patients with autoimmune conditions such as systemic lupus erythematosus and rheumatoid arthritis, but the risk of IHD in Sjögren's syndrome (SjS) is unknown. To fill this knowledge gap, we estimated the prevalence and risk of IHD with SjS compared to controls from the general population using the Healthcare Cost and Utilization Project National Inpatient Sample 2011 database. MATERIALS AND METHODS: The Healthcare Cost and Utilization Project administrative longitudinal database contains encounter-level information on inpatient stays, emergency department visits and ambulatory surgery in all U.S. hospitals. We conducted a cross-sectional study among the inpatient population diagnosed with SjS and matched 1:4 with controls for age, sex and hospital region. Odds ratio for IHD was calculated as cases compared to controls. The contribution of various risk factors to IHD was also evaluated by logistic regression. RESULTS: Analysis demonstrated that 7,154 of 13,086 cases (54.7%) of SjS had IHD compared to 27,367 of 52,448 controls (52.2%). The adjusted odds ratio for IHD in those with SjS was 0.898 (95% CI: 0.844-0.955). Patients with SjS were significantly more likely to have hypertension, diabetes, apnea and lipid disorders. CONCLUSIONS: To our knowledge, this is the largest population-based study investigating the risk of IHD in patients with SjS. We found a modest, though statistically significant, decrease in the risk of IHD in SjS compared to controls.
