With aging of the population, cardiovascular conditions (CC) are increasingly common in individuals undergoing PCI for stable angina pectoris (AP). It is unknown if the overall burden of CCs associates with diminished symptom improvement after PCI for stable AP. We prospectively administered validated surveys assessing AP, dyspnea, and depression to patients undergoing PCI for stable AP at our institution, 2016-2018. The association of CC burden and symptoms at 30-days post-PCI was assessed via linear mixed effects models. Included individuals (N = 121; mean age 68 ± 10 years; response rate = 42%) were similar to non-included individuals. At baseline, greater CC burden was associated with worse dyspnea, depression, and physical limitations due to AP, but not AP frequency or quality of life. PCI was associated with small improvements in AP and dyspnea (p ≤ 0.001 for both), but not depression (p = 0.15). After multivariable adjustment, including for baseline symptoms, CC burden was associated with a greater improvement in AP physical limitations (p = 0.01) and depression (p = 0.002), albeit small, but not other symptom domains (all p ≥ 0.05). In patients undergoing PCI for stable AP, increasing CC burden was associated with worse dyspnea, depression, and AP physical limitations at baseline. An increasing number of CCs was associated with greater improvements, though small, in AP physical limitations and depression. In conclusion, the overall number of cardiovascular conditions should not be used to exclude patients from PCI for stable AP on the basis of an expectation of less symptom improvement.

BACKGROUND:While survival after acute myocardial infarction has improved substantially, older adults remain at heightened risk for hospital readmissions and death. Evidence for the role of cognitive impairment in older myocardial infarction survivors' risk for these outcomes is limited. METHODS:3041 patients aged ≥75 years hospitalized with acute myocardial infarction (mean age 82 ± 5 years, 56% male) recruited from 94 US hospitals. Cognition was assessed using the Telephone Interview for Cognitive Status; scores of <27 and <22 indicated mild and moderate/severe impairment, respectively. Readmissions and death at 6 months post-discharge were ascertained via participant report and medical record review. Associations between cognition and outcomes were evaluated with multivariable-adjusted logistic regression. RESULTS:Mild and moderate/severe cognitive impairment were present in 11% and 6% of the cohort, respectively. Readmission and death at 6 months occurred in 41% and 9% of participants, respectively. Mild and moderate/severe cognitive impairment were associated with increased risk of readmission (odds ratio [OR] 1.36; 95% confidence interval [CI], 1.08-1.72 and OR 1.58; 95% CI, 1.18-2.12, respectively) and death (OR 2.19; 95% CI, 1.54-3.11 and OR 3.82; 95% CI, 2.63-5.56, respectively) in unadjusted analyses. Significant associations between moderate/severe cognitive impairment and death (OR 1.69; 95% CI, 1.10-2.59) persisted after adjustment for demographics, myocardial infarction characteristics, comorbidity burden, functional status, and depression, but not for readmissions. CONCLUSIONS:Moderate-to-severe cognitive impairment is associated with heightened risk of death in older acute myocardial infarction patients in the months after hospitalization, but not with readmission. Routine cognitive screening may identify older myocardial infarction survivors at risk for poor outcomes who may benefit from closer oversight and support in the post-discharge period.

Background Racial disparities in age-associated functional impairments, which are powerful predictors of readmission and mortality after acute myocardial infarction (AMI), have not been described in older AMI patients. Given an aging population and growing recognition of the prognostic value of functional impairments, this is an important knowledge gap. Methods We analyzed data from SILVER-AMI, a prospective cohort study that enrolled patients aged >=75 hospitalized for AMI at 94 sites across the US. Patients were assessed for functional impairments during hospitalization. Patients completed an in-person Telephone Interview for Cognitive Status, a Timed Up and Go test of mobility and a grip strength test. Vision and hearing impairments were self-reported. Patients also reported their prehospital independence in activities of daily living (bathing, dressing, ambulating, rising from a chair). We evaluated racial disparities in functional impairments using Pearson's chi-squared test with Yates' continuity correction. Results Of 3,041 patients, 2,668 (87.7%) identified as white and 325 (10.7%) identified as another race (250 Black, 40 Asian, 15 American Indian or Alaskan Native, 8 Native Hawaiian or Pacific Islander, 12 two or more races). Nonwhite patients were younger (80.9 yr. vs. 81.7 yr.; p<0.01), less likely to have a college degree (35.7% vs. 43.5%; p<0.05) and more often female (59.7% vs. 42.5%; p<0.001). Cognitive impairment was more common among nonwhite patients (35.1% vs. 14.5%; p<0.001), as was mobility impairment (64.3% vs. 54.6%; p<0.001). Weak grip was similarly prevalent in both groups (63.1% vs. 59.4%; p=0.29). Vision impairment was more common among nonwhite patients (50.2% vs. 35.7%; p<0.001), while hearing impairment was less common (38.5% vs. 55.7%; p<0.001). Nonwhite patients were more likely to report a disability in one or more activities of daily living (21.2% vs. 13.0%; p<0.001). Conclusion In this well-characterized AMI cohort, nonwhite patients had a more "geriatric" phenotype despite a younger age, with more functional impairments (cognition, mobility, vision) and a higher rate of disability in one or more activities of daily living.

Background Cardiac rehabilitation (CR) is increasingly being prescribed for adult congenital heart disease (ACHD) patients after cardiac procedures or for reduced exercise tolerance. We aim to describe the functional capacity improvements of ACHD patients in CR. Methods This retrospective study included ACHD patients at NYU Rusk Cardiac Rehabilitation from 2013-2019. We collected data on patient characteristics, number of sessions attended, and exercise testing results. Paired sample t-tests were used to assess for changes between pre- and post-CR exercise time and metabolic equivalents (METs). Results In total, 76 ACHD patients (mean age 38.2 years, 56.6% female, 89.5% moderate or complex conditions by anatomic classification) participated in CR. Referral indication was reduced exercise tolerance for 43.4% and was post-cardiac procedure (transcatheter or surgical) for the remainder. Among 37 patients (48.7%) who finished all 36 CR sessions, complete exercise testing data was available for 29 of them. Exercise time increased by 83.8 seconds (95% CI, 43.9 - 123.8; baseline mean 520.7), METs increased by 1.2 (95% CI, 0.6 - 1.8; baseline mean 8.1), and both parameters increased for 72.4% of these patients. These statistically significant improvements were observed across referral indications. Conclusion On average, CR benefits ACHD patients who complete the program, regardless of referral indication. Efforts to increase CR referral and retention would allow more patients to benefit. [Formula presented]

PURPOSE OF REVIEW:The utility of aspirin and statins for primary prevention of atherosclerotic cardiovascular disease remains ambiguous in older adults. Current guidelines and recent data are vague and inconclusive. This review seeks to summarize the landscape of primary prevention of cardiovascular disease in older adults and explore the role of shared decision making. RECENT FINDINGS:Observational data suggest potential benefit of statin therapy in older adults. Aspirin is presently not recommended for primary prevention based on evidence from recent clinical trials. The implementation of shared decision making and decision aids in routine clinical practice remains challenging but may rise in coming years. Clinical trial data on the horizon may aid in solidifying guideline therapy for statin use. However, in the face of uncertainty, shared decision making between provider and patient should be utilized to determine whether pharmacotherapy may benefit older adults. Decision aids are an effective tool to guide this process.

BACKGROUND:We sought to examine whether people with a diagnosis of cardiovascular disease (CVD) experienced a greater incidence of subsequent cognitive impairment (CI) compared to people without CVD, as suggested by prior studies, using a large longitudinal cohort. METHODS:We employed Health and Retirement Study (HRS) data collected biennially from 1998 to 2014 in 1305 U.S. adults age ≥ 65 newly diagnosed with CVD vs. 2610 age- and gender-matched controls. Diagnosis of CVD was adjudicated with an established HRS methodology and included self-reported coronary heart disease, angina, heart failure, myocardial infarction, or other heart conditions. CI was defined as a score < 11 on the 27-point modified Telephone Interview for Cognitive Status. We examined incidence of CI over an 8-year period using a cumulative incidence function accounting for the competing risk of death. RESULTS:Mean age at study entry was 73 years, 55% were female, and 13% were non-white. Cognitive impairment developed in 1029 participants over 8 years. The probability of death over the study period was greater in the CVD group (19.8% vs. 13.8%, absolute difference 6.0, 95% confidence interval 2.2 to 9.7%). The cumulative incidence analysis, which adjusted for the competing risk of death, showed no significant difference in likelihood of cognitive impairment between the CVD and control groups (29.7% vs. 30.6%, absolute difference - 0.9, 95% confidence interval - 5.6 to 3.7%). This finding did not change after adjusting for relevant demographic and clinical characteristics using a proportional subdistribution hazard regression model. CONCLUSIONS:Overall, we found no increased risk of subsequent CI among participants with CVD (compared with no CVD), despite previous studies indicating that incident CVD accelerates cognitive decline.

BACKGROUND/UNASSIGNED:ADAPTABLE (Aspirin Dosing: A Patient-centric Trial Assessing Benefits and Long-Term Effectiveness) is a pragmatic clinical trial examining high-dose versus low-dose aspirin among patients with cardiovascular disease. ADAPTABLE is leveraging novel approaches for clinical trial conduct to expedite study completion and reduce costs. One pivotal aspect of the trial conduct is maximizing clinician engagement. METHODS/RESULTS/UNASSIGNED:Clinician engagement can be diminished by barriers including time limitations, insufficient research infrastructure, lack of research training, inadequate compensation for research activities, and clinician beliefs. We used several key approaches to boost clinician engagement such as empowering clinician champions, including a variety of clinicians, nurses and advanced practice providers, periodic newsletters and coordinated team celebrations, and deploying novel technological solutions. Specifically, some centers generated electronic health records-based best practice advisories and research dashboards. Future large pragmatic trials will benefit from standardization of the various clinician engagement strategies especially studies leveraging electronic health records-based approaches like research dashboards. Financial or academic "credit" for clinician engagement in clinical research may boost participation rates in clinical studies. CONCLUSION/UNASSIGNED:Maximizing clinician engagement is important for the success of clinical trials; the strategies employed in the ADAPTABLE trial may serve as a template for future pragmatic studies.

BACKGROUND:Oldest-old patients (≥85 years) constitute half the acute myocardial infarction hospitalizations among older adults and more commonly have atypical presentation, under-treatment and functional impairments. Yet this group has not been well characterized. OBJECTIVES/OBJECTIVE:We characterized differences in presentation, functional impairments, treatments, health status, and mortality among middle-old (75-84 years) and oldest-old patients with myocardial infarction. METHODS:We analyzed data from the ComprehenSIVe Evaluation of Risk Factors in Older Patients with AMI (SILVER-AMI) study that enrolled 3041 patients ≥75 years of age from 94 hospitals across the US between 2013-2016. We performed Cox proportional hazards regression to examine the association between the oldest-old (n=831) and middle-old (n=2210) age categories with post-discharge 6-month case fatality rate adjusting for socio-demographic and clinical variables, and mobility impairment. RESULTS:The oldest-old were less likely to present with chest pain (52.7% vs. 57.7%) as their primary symptom or to receive coronary revascularization (58.1% vs. 71.8) (p<0.01 for both). The oldest-old were more likely to have functional impairments and had higher 6-month mortality compared with the middle-old patients (HR 1.78, 95% CI 1.39-2.28). This association was substantially attenuated after adjusting for mobility impairment (HR 1.29, 95% CI 0.99-1.68). CONCLUSIONS:There is considerable heterogeneity in presentation, treatment and outcomes among older patients with myocardial infarction. Mobility impairment, a marker for frailty, modifies the association between advanced age and treatments as well as outcomes.

OBJECTIVE:To develop a 180-day readmission risk model for older adults with acute myocardial infarction (AMI) that considered a broad range of clinical, demographic and age-related functional domains. METHODS:We used data from ComprehenSIVe Evaluation of Risk in Older Adults with AMI (SILVER-AMI), a prospective cohort study that enrolled participants aged ≥75 years with AMI from 94 US hospitals. Participants underwent an in-hospital assessment of functional impairments, including cognition, vision, hearing and mobility. Clinical variables previously shown to be associated with readmission risk were also evaluated. The outcome was 180-day readmission. From an initial list of 72 variables, we used backward selection and Bayesian model averaging to derive a risk model (N=2004) that was subsequently internally validated (N=1002). RESULTS:Of the 3006 SILVER-AMI participants discharged alive, mean age was 81.5 years, 44.4% were women and 10.5% were non-white. Within 180 days, 1222 participants (40.7%) were readmitted. The final risk model included 10 variables: history of chronic obstructive pulmonary disease, history of heart failure, initial heart rate, first diastolic blood pressure, ischaemic ECG changes, initial haemoglobin, ejection fraction, length of stay, self-reported health status and functional mobility. Model discrimination was moderate (0.68 derivation cohort, 0.65 validation cohort), with good calibration. The predicted readmission rate (derivation cohort) was 23.0% in the lowest quintile and 65.4% in the highest quintile. CONCLUSIONS:Over 40% of participants in our sample experienced hospital readmission within 180 days of AMI. Our final readmission risk model included a broad range of characteristics, including functional mobility and self-reported health status, neither of which have been previously considered in 180-day risk models.
