The impact of a statewide payment reform on transcatheter aortic valve replacement (TAVR) utilization and readmissions.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is an increasingly used but relatively expensive procedure with substantial associated readmission rates. It is unknown how cost-constrictive payment reform measures, such as Maryland's All Payer Model, impact TAVR utilization given its relative expense. This study investigated the impact of Maryland's All Payer Model on TAVR utilization and readmissions among Maryland Medicare beneficiaries. METHODS: This was a quasi-experimental investigation of Maryland Medicare patients undergoing TAVR between 2012 and 2018. New Jersey data were used for comparison. Longitudinal interrupted time series analyses were used to study TAVR utilization and difference-in-differences analyses were used to investigate post-TAVR readmissions. RESULTS: During the first year of payment reform (2014), TAVR utilization among Maryland Medicare beneficiaries dropped by 8% (95% confidence interval [CI]: -9.2% to -7.1%; p < 0.001), with no concomitant change in TAVR utilization in New Jersey (0.2%, 95% CI: 0%-1%, p = 0.09). Longitudinally, however, the All Payer Model did not impact TAVR utilization in Maryland compared to New Jersey. Difference-in-differences analyses demonstrated that implementation of the All Payer Model was not associated with significantly greater declines in 30-day post-TAVR readmissions in Maryland versus New Jersey (-2.1%; 95% CI: -5.2% to 0.9%; p =0.1). CONCLUSIONS: Maryland's All Payer Model resulted in an immediate decline in TAVR utilization, likely a result of hospitals adjusting to global budgeting. However, beyond this transition period, this cost-constrictive reform measure did not limit Maryland TAVR utilization. In addition, the All Payer Model did not reduce post-TAVR 30-day readmissions. These findings may help inform expansion of globally budgeted healthcare payment structures.

Myocardial Injury in Severe COVID-19 Compared With Non-COVID-19 Acute Respiratory Distress Syndrome.

BACKGROUND: Knowledge gaps remain in the epidemiology and clinical implications of myocardial injury in coronavirus disease 2019 (COVID-19). We aimed to determine the prevalence and outcomes of myocardial injury in severe COVID-19 compared with acute respiratory distress syndrome (ARDS) unrelated to COVID-19. METHODS: We included intubated patients with COVID-19 from 5 hospitals between March 15 and June 11, 2020, with troponin levels assessed. We compared them with patients from a cohort study of myocardial injury in ARDS and performed survival analysis with primary outcome of in-hospital death associated with myocardial injury. In addition, we performed linear regression to identify clinical factors associated with myocardial injury in COVID-19. RESULTS: Of 243 intubated patients with COVID-19, 51% had troponin levels above the upper limit of normal. Chronic kidney disease, lactate, ferritin, and fibrinogen were associated with myocardial injury. Mortality was 22.7% among patients with COVID-19 with troponin under the upper limit of normal and 61.5% for those with troponin levels >10 times the upper limit of normal (P<0.001). The association of myocardial injury with mortality was not statistically significant after adjusting for age, sex, and multisystem organ dysfunction. Compared with patients with ARDS without COVID-19, patients with COVID-19 were older and had higher creatinine levels and less favorable vital signs. After adjustment, COVID-19-related ARDS was associated with lower odds of myocardial injury compared with non-COVID-19-related ARDS (odds ratio, 0.55 [95% CI, 0.36-0.84]; P=0.005). CONCLUSIONS: Myocardial injury in severe COVID-19 is a function of baseline comorbidities, advanced age, and multisystem organ dysfunction, similar to traditional ARDS. The adverse prognosis of myocardial injury in COVID-19 relates largely to multisystem organ involvement and critical illness.

Radial versus femoral secondary access for transcatheter aortic valve replacement: A systematic review and meta-analysis.

OBJECTIVES: We aimed to evaluate the risk of procedural complications after TAVR using secondary radial access (RA) versus femoral access (FA) through a systematic review and meta-analysis of the published literature. BACKGROUND: Transcatheter aortic valve replacement (TAVR) entails both large-bore arterial access for device delivery and secondary arterial access for hemodynamic and imaging assessments. It is unknown whether RA versus FA for this secondary access reduces the risk of procedural complications. METHODS: We searched PubMed, Embase, the Cochrane Library, and Web of Science for observational studies comparing TAVR procedural complications in RA versus FA. Event rates were compared via weighted summary odds ratios using the Mantel-Haenszel method. RESULTS: Six manuscripts encompassing 6132 patients were included. Meta-analysis showed that RA reduced the risk of major vascular complications (OR 0.58, 95% CI 0.43-0.77, p < 0.001, I2 0%) and major/life-threatening bleeding (OR 0.46, 95% CI 0.36-0.59, p < 0.001, I2 0%) as compared to FA for secondary TAVR access. We also observed a reduction 30-day mortality (OR 0.55, 95% CI 0.38-0.79, p = 0.001, I2 0%), acute kidney injury (OR 0.45, 95% CI 0.34-0.60, p < 0.001, I2 0%), and stroke and transient ischemic attack (OR 0.43, 95% CI 0.27-0.67, p < 0.001, I2 0%). CONCLUSIONS: RA reduced the risk of major vascular and bleeding complications when compared to FA for secondary access in TAVR. RA is associated with reduced risk of other adverse outcomes including mortality, but these associations may be related to selection bias and confounding given the observational study designs.

Frailty and cardiovascular outcomes in the National Health and Aging Trends Study.

AIMS: Physical frailty is a commonly encountered geriatric syndrome among older adults without coronary heart disease (CHD). The impact of frailty on the incidence of long-term cardiovascular outcomes is not known.We aimed to evaluate the long-term association of frailty, measured by the Fried frailty phenotype, with all-cause-mortality and MACE among older adults without a history of CHD at baseline in the National Health and Aging Trends Study. METHODS AND RESULTS: We used the National Health and Aging Trends Study, a prospective cohort study linked to a Medicare sample. Participants with a prior history of CHD were excluded. Frailty was measured during the baseline visit using the Fried physical frailty phenotype. Cardiovascular outcomes were assessed during a 6-year follow-up.Of the 4656 study participants, 3259 (70%) had no history of CHD 1 year prior to their baseline visit. Compared to those without frailty, subjects with frailty were older (mean age 82.1 vs. 75.1 years, P < 0.001), more likely to be female (68.3% vs. 54.9%, P < 0.001), and belong to an ethnic minority. The prevalence of hypertension, falls, disability, anxiety/depression, and multimorbidity was much higher in the frail and pre-frail than the non-frail participants. In a Cox time-to-event multivariable model and during 6-year follow-up, the incidences of death and of each individual cardiovascular outcomes were all significantly higher in the frail than in the non-frail patients including major adverse cardiovascular event (MACE) [hazard ratio (HR) 1.77, 95% confidence interval (CI) 1.53, 2.06], death (HR 2.70, 95% CI 2.16, 3.38), acute myocardial infarction (HR 1.95, 95% CI 1.31, 2.90), stroke (HR 1.71, 95% CI 1.34, 2.17), peripheral vascular disease (HR 1.80, 95% CI 1.44, 2.27), and coronary artery disease (HR 1.35, 95% CI 1.11, 1.65). CONCLUSION: In patients without CHD, frailty is a risk factor for the development of MACEs. Efforts to identify frailty in patients without CHD and interventions to limit or reverse frailty status are needed and, if successful, may limit subsequent adverse cardiovascular events.

Dual Versus Triple Therapy for Atrial Fibrillation After Percutaneous Coronary Intervention: A Systematic Review and Meta-analysis.

Background: The safety and effectiveness of dual therapy (direct oral anticoagulant [DOAC] plus P2Y12 inhibitor) versus triple therapy (vitamin K antagonist plus aspirin and P2Y12 inhibitor) in patients with nonvalvular atrial fibrillation (AF) after percutaneous coronary intervention (PCI) is unclear. Purpose: To examine the effects of dual versus triple therapy on bleeding and ischemic outcomes in adults with AF after PCI. Data Sources: Searches of PubMed, EMBASE, and the Cochrane Library (inception to 31 December 2019) and ClinicalTrials.gov (7 January 2020) without language restrictions; journal Web sites; and reference lists. Study Selection: Randomized controlled trials that compared the effects of dual versus triple therapy on bleeding, mortality, and ischemic events in adults with AF after PCI. Data Extraction: Two independent investigators abstracted data, assessed the quality of evidence, and rated the certainty of evidence. Data Synthesis: Four trials encompassing 7953 patients were selected. At the median follow-up of 1 year, high-certainty evidence showed that dual therapy was associated with reduced risk for major bleeding compared with triple therapy (risk difference [RD], -0.013 [95% CI, -0.025 to -0.002]). Low-certainty evidence showed inconclusive effects of dual versus triple therapy on risks for all-cause mortality (RD, 0.004 [CI, -0.010 to 0.017]), cardiovascular mortality (RD, 0.001 [CI, -0.011 to 0.013]), myocardial infarction (RD, 0.003 [CI, -0.010 to 0.017]), stent thrombosis (RD, 0.003 [CI, -0.005 to 0.010]), and stroke (RD, -0.003 [CI, -0.010 to 0.005]). The upper bounds of the CIs for these effects were compatible with possible increased risks with dual therapy. Limitation: Heterogeneity of study designs, dosages of DOACs, and types of P2Y12 inhibitors. Conclusion: In adults with AF after PCI, dual therapy reduces risk for bleeding compared with triple therapy, whereas its effects on risks for death and ischemic end points are still unclear. Primary Funding Source: None.

Nonprimary PCI at hospitals without cardiac surgery on-site: Consistent outcomes for all?

BACKGROUND: The CPORT-E trial showed the noninferiority of nonprimary percutaneous coronary intervention (PCI) at hospitals without cardiac surgery on-site (SoS) compared with hospitals with SoS for 6-week mortality and 9-month major adverse cardiac events (MACE). However, target vessel revascularization (TVR) was increased at non-SoS hospitals. Therefore, we aimed to determine the consistency of the CPORT-E trial findings across the spectrum of enrolled patients. METHODS: Post hoc subgroup analyses of 6-week mortality and 9-month MACE, defined as the composite of death, Q-wave myocardial infarction, or TVR, were performed. Patients with and without 9-month TVR and rates of related outcomes were compared. RESULTS: There was no interaction between SoS status and clinically relevant subgroups for 6-week mortality or 9-month MACE (P for any interaction=.421 and .062, respectively). In addition to increased 9-month rates of TVR and diagnostic catheterization at hospitals without SoS, non-TVR was also increased (2.7% vs 1.9%, P=.002); there was no difference in myocardial infarction-driven TVR, non-TVR, or diagnostic catheterization. Predictors of 9-month TVR included intra-aortic balloon pump use, any index PCI complication, and 3-vessel PCI, whereas predictors of freedom from TVR included SoS, discharge on a P2Y12 inhibitor, and stent implantation. CONCLUSIONS: The noninferiority of nonprimary PCI at non-SoS hospitals was consistent across clinically relevant subgroups. Elective PCI at an SoS hospital conferred a TVR benefit which may be related to a lower rate of referral for diagnostic catheterization for reasons other than myocardial infarction.

Alternative access for transcatheter aortic valve replacement in older adults: A collaborative study from France and United States.

BACKGROUND: We examined the outcomes of older adults undergoing nontrans-femoral (non-TF) transcatheter aortic valve replacement (TAVR) procedures including trans-apical (TA), trans-aortic (TAo), trans-subclavian (TSub), and trans-carotid (TCa) techniques. METHODS AND RESULTS: This is an observational study of all consecutive older patients who underwent non-TF TAVR for symptomatic severe AS with Edwards Sapien (ES), Medtronic CoreValve, ES3 or Lotus Valve at three centers in France and the United States from 04/2008 to 02/2017. Baseline characteristics and clinical outcomes were defined according to VARC-2 criteria. Of 857 patients who received TAVR, 172 (20%) had an alternative access procedure. Of these, 45 (26%) were TA, 67 (39%) TAo, 17 (10%) TSub, and 43 (25%) TCa procedures. The preference for non-TF access site was different between the two countries (US: TA 39%, TAo 52%, TSub 9%; TCa 0% vs. France: TA 9%, TAo 23%, TSub 11%, and TCa 57%, P-value < .001). Most patients who underwent TAo TAVR were older women (median age: TA 82, TAo 84, TSub 81, TCa 81, P-value = 0.043; female gender: TA 32 (27%), TAo 30 (55%), TSub 10 (41%), TCa 27 (37%), P-value = .021). The predicted Society of Thoracic Surgery risk of mortality was similar among groups (TA 7%, TAo 7%, TSub 6%, TCa 7%, P-value= .738). No differences were observed in the frequency of para-valvular leak, intra-procedural bleeding, vascular complications, conversion to open-heart surgery, or development of acute kidney injury. The highest in-hospital mortality was observed in the TAo group (TA 2%, TAo 15%, TSub 0%, TCa 2%, P-value = .014). However, hospital length of stay, one-month, and one-year mortality were similar among non-TF techniques. CONCLUSION: Although regional differences exist in the choice of alternative access techniques, centers with high technical expertise can provide a safe alternative to traditional TF TAVR. TAo TAVR was associated with higher in-hospital mortality than other non-TF approaches, and this may have reflected patient rather than procedural factors. All alternative access techniques had similar mortality rates and clinical outcomes at one-year follow-up. Trans-carotid access is safe and feasible compared to other non-TF access techniques.

Influence of radial versus femoral access site on coronary angiography and intervention outcomes: A systematic review and meta-analysis.

OBJECTIVES: Systematic review and meta-analysis of randomized clinical trials (RCT) to compare procedural outcomes between radial access (RA) and femoral access (FA). BACKGROUND: Recent RCTs suggest RA for coronary angiography and percutaneous coronary intervention reduces bleeding complications, but controversy exists regarding other benefits and risks relative to FA. METHODS: Searches of MEDLINE, EMBASE, CENTRAL, LILACS, and major conference abstracts identified relevant studies published from 1985-2016. We qualitatively evaluated study methodology and risk of bias. Quantitative data were abstracted relevant to the primary endpoints of major adverse cardiovascular events (MACE) and major bleeding (MB), and secondary outcomes including vascular complications and procedural failure. RESULTS: We identified 2,098 titles, from which 48 studies with 29,446 patients met inclusion criteria for our analysis. We found there was a significant reduction of MACE with RA versus FA (RR 0.86, 95% CI 0.77-0.95, I2 = 0%), driven by a reduction in death, but not MI or stroke. MB occurred less frequently with RA (RR 0.54, 95% CI 0.44-0.67, I2 = 4%). Vascular complications were also reduced with RA (RR 0.39, 95% CI 0.25-0.59, I2 = 75%), while procedural failure was more common (RR 2.15, 95% CI 1.65-2.82, I2 = 53%), although there was significant statistical heterogeneity for both of these outcomes. Most studies demonstrated low risk of selection and attrition biases, but high risk of detection bias. CONCLUSIONS: Radial access reduces the risk of death, major bleeding, and vascular complications as compared to femoral access but increases the risk of procedural failure. © 2017 Wiley Periodicals, Inc.

Heparin versus bivalirudin for non-primary percutaneous coronary intervention: A post-Hoc analysis of the CPORT-E trial.

OBJECTIVES: To compare bivalirudin to heparin during non-primary percutaneous coronary intervention (PCI). BACKGROUND: The optimal anticoagulant to support PCI remains uncertain. METHODS: We performed a propensity score-based analysis comparing clinical outcomes of patients receiving heparin to those receiving bivalirudin during non-primary PCI. RESULTS: Of 18,867 patients in the Cardiovascular Patient Outcomes Research Team Non-Primary PCI (CPORT-E) trial, we selected 7,913 patients undergoing non-staged PCI of whom 57.3% received heparin and 42.7% received bivalirudin. In-hospital myocardial infarction occurred in 4.4% of patients receiving bivalirudin and 3.0% of patients receiving heparin (relative risk [RR] 1.5, 95% confidence interval [CI] 1.1-2.1, P = 0.022); this difference persisted at 6 weeks (5.0% vs. 3.6%, RR 1.4, 95% CI 1.0-1.8, P = 0.041). There was no difference in all-cause mortality either in-hospital (0.2% vs. 0.1% for heparin vs. bivalirudin, P = 0.887) or at 6 weeks (0.5% vs. 0.7%, P = 0.567). In-hospital bleeding requiring transfusion occurred in 0.9% of patients receiving bivalirudin and 1.9% of patients receiving heparin (RR 0.4, 95% CI 0.3-0.7, P <0.001), but there was no difference at 6 weeks (2.7% for heparin vs. 1.9% for bivalirudin, RR 0.7, 95% CI 0.5-1.0, P = 0.062). CONCLUSIONS: In patients undergoing non-primary PCI at hospitals without on-site cardiac surgery, bivalirudin was associated with a decreased risk of in-hospital bleeding requiring transfusion and an increased risk of in-hospital MI compared to heparin. © 2017 Wiley Periodicals, Inc.

An unusual case of infective endocarditis involving a right coronary artery to superior vena cava fistula.

Coronary artery fistulas (CAFs) are rare and mostly congenital anomalous connections between a coronary artery and a cardiac chamber or great vessel. Most CAFs are small, asymptomatic, and found incidentally during cardiac imaging. However, they can lead to serious complications including myocardial infarction, congestive heart failure, arrhythmias, or fistula rupture. CAFs have been associated with infective endocarditis, but to our knowledge, this complication has never been reported involving an isolated CAF to an otherwise anatomically normal great vessel. We report the first case of this complication in a 49-year-old man with a presumed streptococcus vegetation found within an isolated large, tortuous CAF connecting the right coronary artery to the superior vena cava. After completing antibiotic treatment, transcatheter closure of the CAF was performed. Since then, the patient has remained symptom-free. This case demonstrates that CAF closure is feasible following CAF-associated endocarditis, and that closure may represent a viable strategy for reducing risk of recurrent infection.

Transcatheter aortic valve replacement: historical perspectives, current evidence, and future directions.

Severe aortic stenosis (AS) results in considerable morbidity and mortality without aortic valve replacement and is expected to increase in prevalence with the aging population. Because AS primarily affects the elderly, many patients with comorbidities are poor candidates for surgical aortic valve replacement (SAVR) and may not be referred. Transcatheter aortic valve replacement (TAVR) has emerged as transformative technology for the management of AS over the past decade. Randomized trials have established the safety and efficacy of TAVR with improved mortality and quality of life compared with medical therapy in inoperable patients, while demonstrating noninferiority and even superiority to SAVR among high-risk operative candidates. However, early studies demonstrated an early penalty of stroke and vascular complications with TAVR as well as increased paravalvular leak as compared with SAVR. Two device platforms have been evaluated and approved for use in the United States: the Edwards SAPIEN and the Medtronic CoreValve. Early studies also suggest cost-effectiveness for TAVR. Ongoing studies are evaluating new iterations of the aforementioned TAVR devices, novel device designs, and applications of TAVR in expanded populations of patients including those with lower risk profiles as well as those with comorbidities that were excluded from early clinical trials. Future improvements in TAVR technology will likely reduce periprocedural and long-term complications. Further studies are needed to confirm device durability over long-term follow-up and explore the applicability of TAVR to broader AS patient populations.

Economic Burden of Inpatient Care for Mitral Regurgitation in Maryland.

BACKGROUND: Mitral regurgitation (MR) is the most common valvular disease in the United States and increases the risk of death and hospitalization. The economic burden of MR in the United States is not known. METHODS AND RESULTS: We analyzed inpatient hospitalization data from the 1 221 173 Maryland residents who had any in-state admissions from October 1, 2015, to September 30, 2019. We assessed the total charges for patients without MR and for patients with MR who underwent medical management, transcatheter mitral valve repair or replacement, or surgical mitral valve repair or replacement. During the study period, 26 076 inpatients had a diagnosis of MR. Compared with patients without MR, these patients had more comorbidities and higher inpatient mortality. Patients with medically managed MR incurred average total charges of $23 575 per year; MR was associated with $10 559 more in charges per year and an incremental 3.1 more inpatient days per year as compared with patients without MR. Both surgical mitral valve repair or replacement and transcatheter mitral valve repair or replacement were associated with higher charges as compared with medical management during the year of intervention ($47 943 for surgical mitral valve repair or replacement and $63 108 for transcatheter mitral valve repair or replacement). Annual charges for both groups were significantly lower as compared with medical management in the second and third years postintervention. CONCLUSIONS: MR is associated with higher mortality and inpatient charges. Patients who undergo surgical or transcatheter intervention incur lower charges compared with medically managed MR patients in the years after the procedure.

Outcomes among patients undergoing transcatheter aortic valve replacement with very low baseline gradients.

Background: While there is evidence that patients with low-flow, low-gradient aortic stenosis (AS) benefit from transcatheter aortic valve replacement (TAVR), data are lacking regarding outcomes of patients with a very low gradient (VLG). Methods: In this retrospective, single-center study of patients with severe AS who underwent TAVR, three groups were defined using baseline mean aortic valve gradient: VLG (≤25 mmHg), low gradient (LG, 26-39 mmHg), and high gradient (HG, ≥40 mmHg). The primary outcome was the composite of Kansas City Cardiomyopathy Questionnaire (KCCQ)-12 of <45, decrease in KCCQ-12 of ≥10 compared with baseline, or death at 1 year. Results: One-thousand six patients were included: 571 HG, 353 LG, and 82 VLG. The median age was 82.1 years [interquartile range (IQR) 76.3-86.9]; VLG patients had more baseline comorbidities compared with the other groups. The primary outcome was highest at 1 year in the VLG group (VLG, 46.7%; LG, 29.9%; HG, 23.1%; p = 0.002), with no difference between groups after adjustment for baseline characteristics. At baseline, <30% of VLG patients had an excellent or good (50-100) KCCQ-12, whereas more than 75% and 50% had an excellent or good KCCQ-12 at 30-day and 1-year follow-up, respectively. Conclusion: Although patients with VLG undergoing TAVR have a higher rate of poor outcomes at 1 year compared with patients with LG and HG severe AS, this difference is largely attributable to baseline comorbidities. Patients with severe AS undergoing TAVR have significant improvement in health status outcomes regardless of resting mean gradient.

Hierarchical Development of Physical Frailty and Cognitive Impairment and Their Association With Incident Cardiovascular Disease.

BACKGROUND: Frailty and cognitive impairment (CI) are geriatric conditions that lead to poor health outcomes among older adults with cardiovascular disease. The association between their temporal patterns of development and cardiovascular risk is unknown. OBJECTIVES: This study aims to examine the 5-year cardiovascular outcomes by the pattern of development of frailty and CI in older adults without a history of coronary artery disease. METHODS: We used the National Health and Aging Trends Study, linked to Medicare data. Frailty was measured using the physical frailty phenotype. CI was measured using the AD8 Dementia Screening Interview, measured cognitive performance, or self-report by patient or caregiver for a diagnosis given by a physician. The primary outcome was incident major adverse cardiovascular event at 5 years. RESULTS: Of a total 2,189 study participants aged 65 and older, 38.5% were male. In this study population, 154 (7%) participants developed frailty first, 829 (38%) developed CI first, and 195 (9%) participants developed both simultaneously (frail-CI group). Those who developed frailty and CI simultaneously were older, more likely to be female, and had multiple chronic conditions. The frail-CI group had the highest risk of major adverse cardiovascular event (hazard ratio [HR]: 1.81; 95% CI: 1.47-2.23) followed by frail first (HR: 1.46; 95% CI: 1.17-1.81) and CI first (HR: 1.31; 95% CI: 1.15-1.50). Frailty first was associated with the greater risk of stroke (HR: 1.49; 95% CI: 1.06-2.09) compared to the intact group. CONCLUSIONS: The simultaneous development of frailty and CI is associated with an increased risk of adverse cardiovascular outcomes including death compared with the development of each syndrome alone. Diagnostics to detect frailty and CI are critical in assessment of cardiovascular risk in the older population.

Inequities in Aortic Stenosis and Aortic Valve Replacement Between Black/African-American, White, and Hispanic Residents of Maryland.

Background Racial and ethnic inequities exist in surgical aortic valve replacement for aortic stenosis (AS), and early studies have suggested similar inequities in transcatheter aortic valve replacement. Methods and Results We performed a retrospective analysis of the Maryland Health Services Cost Review Commission inpatient data set from 2016 to 2018. Black patients had half the incidence of any inpatient AS diagnosis compared with White patients (incidence rate ratio [IRR], 0.50; 95% CI, 0.48-0.52; P<0.001) and Hispanic patients had one fourth the incidence compared with White patients (IRR, 0.25; 95% CI, 0.22-0.29; P<0.001). Conversely, the incidence of any inpatient mitral regurgitation diagnosis did not differ between White and Black patients (IRR, 1.00; 95% CI, 0.97-1.03; P=0.97) but was significantly lower in Hispanic compared with White patients (IRR, 0.36; 95% CI, 0.33-0.40; P<0.001). After multivariable adjustment, Black race was associated with a lower incidence of surgical aortic valve replacement (IRR, 0.67; 95% CI, 0.55-0.82 P<0.001 relative to White race) and transcatheter aortic valve replacement (IRR, 0.77; 95% CI, 0.65-0.90; P=0.002) among those with any inpatient diagnosis of AS. Hispanic patients had a similar rate of surgical aortic valve replacement and transcatheter aortic valve replacement compared with White patients. Conclusions Hospitalization with any diagnosis of AS is less common in Black and Hispanic patients than in White patients. In hospitalized patients with AS, Black race is associated with a lower incidence of both surgical aortic valve replacement and transcatheter aortic valve replacement compared with White patients, whereas Hispanic patients have a similar incidence of both. The reasons for these inequities are likely multifactorial.

Physical Frailty Phenotype and the Development of Geriatric Syndromes in Older Adults with Coronary Heart Disease.

BACKGROUND: Frailty, a clinical state of vulnerability, is associated with subsequent adverse geriatric syndromes in the general population. We examined the long-term impact of frailty on geriatric outcomes among older patients with coronary heart disease. METHODS: We used the National Health and Aging Trends Study, a prospective cohort study linked to a Medicare sample. Coronary heart disease was identified by self-report or International Classification of Diseases (ICD) codes 1-year prior to the baseline visit. Frailty was measured using the Fried physical frailty phenotype. Geriatric outcomes were assessed annually during a 6-year follow-up. RESULTS: Of the 4656 participants, 1213 (26%) had a history of coronary heart disease 1-year prior to their baseline visit. Compared to those without frailty, subjects with frailty were older (ages ≥75: 80.9% vs 68.9%, P < 0.001), more likely to be female, and belong to an ethnic minority. The prevalence of hypertension, stroke, falls, disability, anxiety/depression, and multimorbidity were much higher in the frail, than nonfrail, participants. In a discrete time survival model, the incidence of geriatric syndromes during 6-year follow-up including 1) dementia, 2) loss of independence, 3) activities of daily living disability, 4) instrumental activities of daily living disability, and 5) mobility disability were significantly higher in the frail than in the nonfrail older patients with coronary heart disease. CONCLUSION: In patients with coronary heart disease, frailty is a risk factor for the accelerated development of geriatric outcomes. Efforts to identify frailty in the context of coronary heart disease are needed, as well as interventions to limit or reverse frailty status for older patients with coronary heart disease.
