Contemporary Revascularization Dilemmas in Older Adults

Frailty, age, and treatment effect of surgical coronary revascularization in ischemic cardiomyopathy: a post hoc analysis of the STICHES trial

Frailty is common among older patients with heart failure (HF). The efficacy of coronary artery bypass grafting (CABG) on the risk of mortality among frail patients with ischemic cardiomyopathy and HF is uncertain, and whether frailty burden modifies the treatment benefits of CABG among these patients is unknown. We performed a post hoc analysis of the STICHES trial, a randomized trial of CABG with medical therapy vs medical therapy alone among participants with ischemic cardiomyopathy with ejection fraction ≤ 35%. Baseline frailty was assessed through a Rockwood Frailty Index (FI), and based on FI cut-offs from prior HF studies, participants with FI ≥ 0.311 were classified as more frail, and those with FI < 0.311 were classified as less frail. A multivariable Cox proportional hazard model with multiplicative interaction terms was constructed to evaluate whether frailty status modified the treatment effect of CABG on mortality in the overall trial cohort and among those < 60 vs ≥ 60 years of age. Of 1187 participants (12.4% female, 2.6% Black, median FI = 0.33 [IQR 0.27-0.39]), 678 were characterized as more frail. Frailty burden did not modify the efficacy of CABG on the risk of all-cause death in the overall cohort (Pint CABG × frailty = 0.2). In age stratified analysis, Baseline frailty status did not modify the treatment effect of CABG on the risk of all-cause mortality among younger (< 60 years, Pint CABG × frailty = 0.2) as well as older participants (≥60 years, Pint CABG × frailty = 0.6). In this post hoc analysis of the STICHES trial, baseline frailty status did not modify the efficacy of CABG in the overall cohort as well as among younger or older participants. Frailty alone should not be used as a criterion to determine the utilization of CABG among patients with ischemic cardiomyopathy.

Acute Coronary Syndrome in Elderly Patients: How to Tackle Them?

Elderly patients diagnosed with acute coronary syndromes (ACS) represent a growing demographic population. These patients typically present more comorbidities and experience poorer outcomes compared to younger patients. Furthermore, they are less frequently subjected to revascularization procedures and are less likely to receive evidence-based medications in both the short and long-term periods. Assessing frailty is crucial in elderly patients with ACS because it can influence management decisions, as well as risk stratification and prognosis. Indeed, treatment decisions should consider geriatric syndromes, frailty, polypharmacy, sarcopenia, nutritional deficits, prevalence of comorbidities, thrombotic risk, and, at the same time, an increased risk of bleeding. Rigorous clinical assessments, clear revascularization criteria, and tailored approaches to antithrombotic therapy are essential for guiding personalized treatment decisions in these individuals. Assessing frailty helps healthcare providers identify patients who may benefit from targeted interventions to improve their outcomes and quality of life. Elderly individuals who experience ACS remain significantly underrepresented and understudied in randomized controlled trials. For this reason, the occurrence of ACS in the elderly continues to be a particularly complex issue in clinical practice, and one that clinicians increasingly have to address, given the general ageing of populations. This review aims to address the complex aspects of elderly patients with ACS to help clinicians make therapeutic decisions when faced with such situations.

Antiplatelet Therapy for Elderly Patients with Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention

The elderly represent an increasing proportion of patients presenting with acute coronary syndrome (ACS). Various data have shown that the benefits of percutaneous coronary revascularization are maintained in elderly patients presenting with ACS. Conversely, the management of antiplatelet therapy remains challenging and controversial, because older patients are usually at a high risk of both ischemia and bleeding. Moreover, the recommended ischemic and bleeding risk scores in patients with ACS were developed from studies with a low representation of older patients. New antiplatelet strategies have been developed, but their evidence in elderly patients is limited because they are usually underrepresented in randomized clinical trials due to their clinical complexity. The aim of this review is to summarize the different factors associated with increased ischemic and/or bleeding risk and the scientific evidence about the different antiplatelet strategies in elderly patients presenting with ACS and undergoing percutaneous coronary revascularization.

Cardiovascular Interventions in Patients With Active and Advanced Malignancy: An Updated Review

In the context of active, advanced malignancies, the recommendation for invasive cardiac interventions is grounded primarily in evidence from trials focused on specific cardiovascular conditions. However, the inclusion of individuals with advanced malignancies in these trials has historically been limited, and the intricate interplay between cancer and cardiovascular disease poses unique challenges for treatment decisions. In this comprehensive review, we delve into the complex landscape of invasive cardiac interventions and their applicability in patients with active, advanced cancer. Our analysis encompasses a range of cardiovascular scenarios, including ST-segment elevation myocardial infarction, non-ST-segment elevation acute coronary syndromes, multivessel coronary disease, severe symptomatic aortic stenosis, and cardiomyopathy. We critically examine the available data and evidence, shedding light on the benefits and potential risks associated with invasive cardiac procedures in the presence of advanced malignancies. Acknowledging the competing risk of mortality posed by advanced cancers, we delve into the contemporary survival expectations for patients across various types of active, advanced malignancies. By synthesizing current literature and exploring cardiovascular interventions within these populations, we aim to establish a well-informed framework. Our ultimate goal is to provide clinicians with a rational guide for making nuanced clinical recommendations regarding the utilization of invasive cardiac interventions in the challenging context of active, advanced cancer.

Representation of Older Adults in the ACC/AHA/SCAI Guideline for Coronary Artery Revascularization

This cross-sectional study assesses the generalizability of the American College of Cardiology/American Heart Association/Society for Cardiovascular Angiography and Interventions (ACC/AHA/SCAI) guideline by examining the representation of older adults in studies cited in the guideline.

Predictors of major adverse cardiac and cerebrovascular events after percutaneous coronary intervention in older adults: a systematic review and meta-analysis

AIM

We systematically reviewed and meta-analyzed the predictors of major adverse cardiac and cerebrovascular events (MACE/MACCE) in older adults who underwent PCI.

METHODS

Three databases, PubMed, Embase, and Scopus, were searched for observational studies considering the out-of-hospital MACE/MACCE in adults ≥ 60 years old with coronary artery disease (acute or chronic) who underwent PCI. Studies were eligible if they had determined at least two statistically significant predictors of MACE/MACCE by multivariable analysis. We used the QUIPS tool to evaluate the risk of bias in the studies. Random-effects meta-analysis was utilized to pool the hazard ratios (HRs) of the most reported predictors.

RESULTS

A total of 34 studies were included in the review. Older age (HR = 1.04, 95% Confidence Interval (CI): 1.03-1.06, P-value < 0.001), diabetes (HR = 1.36, 95% CI: 1.22-1.53, P < 0.001), history of myocardial infarction (MI) (HR = 1.88, 95% CI: 1.37-2.57, P < 0.001), ST-elevation MI (STEMI) at presentation (HR = 1.72, 95% CI: 1.37-2.18, P < 0.001), reduced left ventricular ejection fraction (LVEF) (HR = 2.01, 95% CI: 1.52-2.65, P < 0.001), successful PCI (HR = 0.35, 95% CI: 0.27-0.47, P < 0.001), eGFR (HR = 0.99, 95% CI: 0.97-1.00; P-value = 0.04) and left main coronary artery (LMCA) disease (HR = 2.07, 95% CI: 1.52-2.84, P < 0.001) were identified as predictors of MACE.

CONCLUSION

We identified older age, diabetes, history of MI, STEMI presentation, lower LVEF, and LMCA disease increased the risk of MACE/MACCE after PCI in older adults. Meanwhile, higher eGFR and successful PCI predicted lower adverse events risk. Future studies should focus on a more robust methodology and a precise definition of MACE.

Cardiogenic Shock in Older Adults: A Focus on Age-Associated Risks and Approach to Management: A Scientific Statement From the American Heart Association

Cardiogenic shock continues to portend poor outcomes, conferring short-term mortality rates of 30% to 50% despite recent scientific advances. Age is a nonmodifiable risk factor for mortality in patients with cardiogenic shock and is often considered in the decision-making process for eligibility for various therapies. Older adults have been largely excluded from analyses of therapeutic options in patients with cardiogenic shock. As a result, despite the association of advanced age with worse outcomes, focused strategies in the assessment and management of cardiogenic shock in this high-risk and growing population are lacking. Individual programs oftentimes develop upper age limits for various interventional strategies for their patients, including heart transplantation and durable left ventricular assist devices. However, age as a lone parameter should not be used to guide individual patient management decisions in cardiogenic shock. In the assessment of risk in older adults with cardiogenic shock, a comprehensive, interdisciplinary approach is central to developing best practices. In this American Heart Association scientific statement, we aim to summarize our contemporary understanding of the epidemiology, risk assessment, and in-hospital approach to management of cardiogenic shock, with a unique focus on older adults.

The Impact of Geriatric Conditions in Elderly Patients with Coronary Heart Disease: A State-of-the-Art Review

The growing geriatric population presenting with coronary artery disease poses a primary challenge for healthcare services. This is a highly heterogeneous population, often underrepresented in studies and clinical trials, with distinctive characteristics that render them particularly vulnerable to standard management/approaches. In this review, we aim to summarize the available evidence on the treatment of acute coronary syndrome in the elderly. Additionally, we contextualize frailty, comorbidity, sarcopenia, and cognitive impairment, common in these patients, within the realm of coronary artery disease, proposing strategies for each case that may assist in therapeutic approaches.

Factors of Hospital Mortality in Men and Women with ST-Elevation Myocardial Infarction - An Observational, Retrospective, Single Centre Study

Purpose

There are well-known gender differences in mortality of patients with ST-elevation myocardial infarction (STEMI). Our purpose was to assess factors of hospital mortality separately for men and women with STEMI, which are less well known.

Patients and Methods

In 2018-2019, 485 men and 214 women with STEMI underwent treatment with primary percutaneous coronary intervention (PCI). We retrospectively compared baseline characteristics, treatments and hospital complications between men and women, as well as between nonsurviving and surviving men and women with STEMI.

Results

Primary PCI was performed in 94% of men and 91.1% of women with STEMI, respectively. The in-hospital mortality was significantly higher in women than in men (14% vs 8%, p=0.019). Hospital mortality in both genders was associated significantly to older age, heart failure, prior resuscitation, acute kidney injury, to less likely performed and less successful primary PCI and additionally in men to hospital infection and in women to bleeding. In men and women ≥65 years, mortality was similar (13.3% vs 17.8%, p = 0.293).

Conclusion

Factors of hospital mortality were similar in men and women with STEMI, except bleeding was more likely observed in nonsurviving women and infection in nonsurviving men.

Review and Key Takeaways of the 2021 Percutaneous Coronary Intervention Guidelines

The 2021 Percutaneous Coronary Intervention guidelines completed by American College of Cardiology/American Heart Association/Society for Cardiovascular Angiography and Interventions provide a set of guidelines regarding revascularization strategies. With emphasis on equity of care, multidisciplinary heart team use, revascularization for acute coronary syndrome, and stable ischemic heart disease, the guidelines create a thorough framework with recommendations regarding therapeutic strategies. In this comprehensive review, our aim is to summarize the 2021 revascularization guidelines and analyze key points regarding each recommendation.

The impact of on-site cardiac surgical backup on clinical outcomes of acute coronary syndrome-analysis of the ACSIS national registry

Background

The availability of advanced technologies for mechanical support in hospitals with on-site cardiac surgery (CS), along with the ability to perform urgent coronary artery bypass graft (CABG) surgery, may result in improved clinical outcomes in patients with acute coronary syndrome (ACS).

Methods

We conducted a retrospective analysis of the bi-annually Acute Coronary Syndrome Israeli Survey (ACSIS) registry from the year 2000 to 2020, performed in hospitals with and without CS. Mortality rates and major adverse cardiac and cerebrovascular events (MACCE) rates are reported. We evaluated two periods of the study-early (2000-2010) vs. late (2011-2020). Propensity score matching was performed to reduce bias between the two groups.

Results

The study included 16,979 patients (52.3% in the on-site CS group). Patients in the on-site CS group were more likely to undergo percutaneous coronary intervention (PCI), (odds ratio [OR], 1.26 [95% CI, 1.18-1.35]; p < 0.001) and CABG [OR, 1.91 (95%CI, 1.63-2.24); P < 0.001], and patients in hospitals without on-site CS had higher 30-day MACCE [OR, 1.17 (95% CI, 1.07-1.27); p < 0.0005]. Overall, there was no difference in 1-year mortality (hazard ratio [HR], 0.98 [95% CI, 0.89-1.08]; p = 0.71) between the groups. During the late period of the study, patients in the group without on-site CS had lower 30-day mortality [OR, 0.69 (95% CI, 0.49-0.97); P = 0.04], yet with no difference in 1-year mortality [HR, 0.81 (95% CI, 0.65-1.01); p = 0.07].

Conclusions

The availability of on-site CS resulted in variations in treatment modality, yet it did not affect the clinical outcomes of ACS. A trend to a better short-term outcomes was noted in hospitals without CS during the late period of the study, which warrants further investigation.

Prognostic Impact of Percutaneous Coronary Intervention in Older Patients Hospitalized with Acute Myocardial Infarction: Real-World Findings from the Lombardy Health Database

BACKGROUND

Older patients are less likely to receive percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) compared to younger patients. We investigated the prognostic impact of PCI in a large population of patients hospitalized with AMI in the period 2003-2018 by using the administrative Lombardy Health Database (Italy).

METHODS

We considered all patients aged ≥75 years hospitalized with AMI (either STEMI or NSTEMI) from 2003 to 2018 in Lombardy. Patients were grouped according to whether they were treated or not with PCI during the index hospitalization. The primary outcome was in-hospital mortality. The secondary endpoints were 1-year mortality and 1-year re-hospitalization for acute heart failure (AHF) or AMI.

RESULTS

116,063 patients aged ≥75 years (mean age 83 ± 6; 48% males; 46% STEMI) were hospitalized with a primary diagnosis of AMI. Thirty-seven percent of them (n = 42,912) underwent PCI. The in-hospital mortality rate was significantly lower in PCI-treated patients (6% vs. 15%; p < 0.0001). One-year mortality and 1-year re-hospitalization for AHF/AMI were less frequent in PCI-treated patients (16% vs. 41% and 15% vs. 21%, respectively; p < 0.0001). The adjusted risks of the study endpoints were lower in PCI-treated patients: OR 0.37 (95% CI 0.36-0.39) for in-hospital mortality; HR 0.37 (95% CI 0.36-0.38) for 1-year mortality; HR 0.74 (95% CI 0.71-0.77) for 1-year re-hospitalization for AHF/AMI. Similar results were found in STEMI and NSTEMI patients considered separately.

CONCLUSIONS

Our real-world data showed that in patients with AMI ≥ 75 years of age, PCI use is associated with lower in-hospital and 1-year mortality.

Management of Stable Angina in the Older Adult Population

As society ages, the number of older adults with stable ischemic heart disease continues to rise. Older adults exhibit the greatest morbidity and mortality from stable angina. Furthermore, they suffer a higher burden of comorbidity and adverse events from treatment than younger patients. Given that older adults were excluded or underrepresented in most randomized controlled trials of stable ischemic heart disease, evidence for management is limited and hinges on subgroup analyses of trials and observational studies. This review aims to elucidate the current definitions of aging, assess the overall burden and clinical presentations of stable ischemic heart disease in older patients, weigh the available evidence for guideline-recommended treatment options including medical therapy and revascularization, and propose a framework for synthesizing complex treatment decisions in older adults with stable angina. Due to evolving goals of care in older patients, it is paramount to readdress the patient's priorities and preferences when deciding on treatment. Ultimately, the management of stable angina in older adults will need to be informed by dedicated studies in representative populations emphasizing patient-centered end points and person-centered decision-making.

Nonagenarians admission and prognosis in a tertiary center intensive coronary care unit - a prospective study

BACKGROUND

With increasing life expectancy, the prevalence of nonagenarians with cardiovascular disease is steadily growing. However, this population is underrepresented in randomized trials and thus poorly defined, with little quality evidence to support and guide optimal management. The aim of the present study was to evaluate the clinical management, therapeutic approach, and outcomes of nonagenarians admitted to a tertiary care center intensive coronary care unit (ICCU).

METHODS

We prospectively collected all patients admitted to a tertiary care center ICCU between July 2019 - July 2022 and compared nonagenarians to all other patients. The primary outcome was in-hospital mortality.

RESULTS

A total of 3807 patients were included in the study. Of them 178 (4.7%) were nonagenarians and 93 (52%) females. Each year the prevalence of nonagenarians has increased from 4.0% to 2019, to 4.2% in 2020, 4.6% in 2021 and 5.3% in 2022. Admission causes differed between groups, including a lower rate of acute coronary syndromes (27% vs. 48.6%, p < 0.001) and a higher rate of septic shock (4.5% vs. 1.2%, p < 0.001) in nonagenarians. Nonagenarians had more comorbidities, such as hypertension, renal failure, and atrial fibrillation (82% vs. 59.6%, 23% vs. 12.9%, 30.3% vs. 14.4% p < 0.001, respectively). Coronary intervention was the main treatment approach, although an invasive strategy was less frequent in nonagenarians in comparison to younger subjects. In-hospital mortality rate was 2-fold higher in the nonagenarians (5.6% vs. 2.5%, p = 0.025).

CONCLUSION

With increasing life expectancy, the prevalence of nonagenarians in ICCU's is expected to increase. Although nonagenarian patients had more comorbidities and higher in-hospital mortality, they generally have good outcomes after admission to the ICCU. Hence, further studies to create evidence-based practices and to support and guide optimal management in these patients are warranted.

The influence of pressure injury risk on the association between left ventricular ejection fraction and all-cause mortality in patients with acute myocardial infarction 80 years or older

BACKGROUND

We aimed to investigate whether the pressure injury risk mediates the association of left ventricular ejection fraction (LVEF) with all-cause death in patients with acute myocardial infarction (AMI) aged 80 years or older.

METHODS

This retrospective cohort study included 677 patients with AMI aged 80 years or older from a tertiary-level hospital. Pressure injury risk was assessed using the Braden scale at admission, and three risk groups (low/minimal, intermediate, high) were defined according to the overall score of six different variables. LVEF was measured during the index hospitalization for AMI. All-cause death after hospital discharge was the primary outcome.

RESULTS

Over a median follow-up period of 1,176 d (interquartile range [IQR], 722-1,900 d), 226 (33.4%) patients died. Multivariate Cox regression analysis showed that reduced LVEF was associated with an increased risk of all-cause death only in the high-risk group of pressure injury (adjusted hazard ratios [HR]=1.81, 95% confidence interval [CI]: 1.03-3.20; P=0.040), but not in the low/minimal- (adjusted HR=1.29, 95%CI: 0.80-2.11; P=0.299) or intermediate-risk groups (adjusted HR=1.14, 95%CI: 0.65-2.02; P=0.651). Significant interactions were detected between pressure injury risk and LVEF (adjusted P=0.003). The cubic spline with hazard ratio plot revealed a distinct shaped curve relation between LVEF and all-cause death among different pressure injury risk groups.

CONCLUSIONS

In older patients with AMI, the risk of pressure injury mediated the association between LVEF and all-cause death. The classification of older patients for both therapy and prognosis assessment appears to be improved by the incorporation of pressure injury risk assessment into AMI care management.

Strategies for Reducing Vascular and Bleeding Risk for Percutaneous Left Ventricular Assist Device-supported High-risk Percutaneous Coronary Intervention

In patients at high risk for haemodynamic instability during percutaneous coronary intervention (PCI), practitioners are increasingly opting for prophylactic mechanical circulatory support, such as the Impella® heart pump (Abiomed, Danvers, MA, USA). Though Impella-supported high-risk PCI (HRPCI) ensures haemodynamic stability during the PCI procedure, access-related complication rates have varied significantly in published studies. Reported variability in complication rates relates to many factors, including anticoagulation practices, access and closure strategy, post-procedure care and variations in event definitions. This article aims to outline optimal strategies to minimize vascular and bleeding complications during Impella-supported HRPCI based on previously identified clinical, procedural and postprocedural risk factors. Practices to reduce complications include femoral skills training, standardized protocols to optimize access, closure, anticoagulation management and post-procedural care, as well as the application of techniques and technological advances. Protocols integrating these strategies to mitigate access-related bleeding and vascular complications for Impella-supported procedures can markedly limit vascular access risk as a barrier to appropriate large-bore mechanical circulatory support use in HRPCI.

The Aging Heart: A Molecular and Clinical Challenge

Aging is associated with an increasing burden of morbidity, especially for cardiovascular diseases (CVDs). General cardiovascular risk factors, ischemic heart diseases, heart failure, arrhythmias, and cardiomyopathies present a significant prevalence in older people, and are characterized by peculiar clinical manifestations that have distinct features compared with the same conditions in a younger population. Remarkably, the aging heart phenotype in both healthy individuals and patients with CVD reflects modifications at the cellular level. An improvement in the knowledge of the physiological and pathological molecular mechanisms underlying cardiac aging could improve clinical management of older patients and offer new therapeutic targets.

Prognostic value of cardiac magnetic resonance early after ST-segment elevation myocardial infarction in older patients

BACKGROUND

older patients with ST-segment elevation myocardial infarction (STEMI) represent a very high-risk population. Data on the prognostic value of cardiac magnetic resonance (CMR) in this scenario are scarce.

METHODS

the registry comprised 247 STEMI patients over 70 years of age treated with percutaneous intervention and included in a multicenter registry. Baseline characteristics, echocardiographic parameters and CMR-derived left ventricular ejection fraction (LVEF, %), infarct size (% of left ventricular mass) and microvascular obstruction (MVO, number of segments) were prospectively collected. The additional prognostic power of CMR was assessed using adjusted C-statistic, net reclassification index (NRI) and integrated discrimination improvement index (IDI).

RESULTS

during a 4.8-year mean follow-up, the number of first major adverse cardiac events (MACE) was 66 (26.7%): 27 all-cause deaths and 39 re-admissions for acute heart failure. Predictors of MACE were GRACE score (HR 1.03 [1.02-1.04], P < 0.001), CMR-LVEF (HR 0.97 [0.95-0.99] per percent increase, P = 0.006) and MVO (HR 1.24 [1.09-1.4] per segment, P = 0.001). Adding CMR data significantly improved MACE prediction compared to the model with baseline and echocardiographic characteristics (C-statistic 0.759 [0.694-0.824] vs. 0.685 [0.613-0.756], NRI = 0.6, IDI = 0.08, P < 0.001). The best cut-offs for independent variables were GRACE score > 155, LVEF < 40% and MVO ≥ 2 segments. A simple score (0, 1, 2, 3) based on the number of altered factors accurately predicted the MACE per 100 person-years: 0.78, 5.53, 11.51 and 78.79, respectively (P < 0.001).

CONCLUSIONS

CMR data contribute valuable prognostic information in older patients submitted to undergo CMR soon after STEMI. The Older-STEMI-CMR score should be externally validated.

In-hospital risk stratification algorithm of Asian elderly patients

Limited research has been conducted in Asian elderly patients (aged 65 years and above) for in-hospital mortality prediction after an ST-segment elevation myocardial infarction (STEMI) using Deep Learning (DL) and Machine Learning (ML). We used DL and ML to predict in-hospital mortality in Asian elderly STEMI patients and compared it to a conventional risk score for myocardial infraction outcomes. Malaysia's National Cardiovascular Disease Registry comprises an ethnically diverse Asian elderly population (3991 patients). 50 variables helped in establishing the in-hospital death prediction model. The TIMI score was used to predict mortality using DL and feature selection methods from ML algorithms. The main performance metric was the area under the receiver operating characteristic curve (AUC). The DL and ML model constructed using ML feature selection outperforms the conventional risk scoring score, TIMI (AUC 0.75). DL built from ML features (AUC ranging from 0.93 to 0.95) outscored DL built from all features (AUC 0.93). The TIMI score underestimates mortality in the elderly. TIMI predicts 18.4% higher mortality than the DL algorithm (44.7%). All ML feature selection algorithms identify age, fasting blood glucose, heart rate, Killip class, oral hypoglycemic agent, systolic blood pressure, and total cholesterol as common predictors of mortality in the elderly. In a multi-ethnic population, DL outperformed the TIMI risk score in classifying elderly STEMI patients. ML improves death prediction by identifying separate characteristics in older Asian populations. Continuous testing and validation will improve future risk classification, management, and results.

Frailty and cardiac surgery: to operate or not?

PURPOSE OF REVIEW

With an aging cardiac surgery population, prefrail and frail patients are becoming more common. Anesthesiologists will be faced with the decision of how best to provide care to frail patients. Identification, management, and outcomes in frail patients will be discussed in this review.

RECENT FINDINGS

Frailty is associated with a variety of poor outcomes, such as increased hospital length of stay, medical resource utilization, readmission rates, and mortality. Prehabilitation may play a greater role in the management of frail cardiac surgery patients.

SUMMARY

As frailty will likely only increase amongst cardiac surgery patients, it is important to develop multicenter trials to study management and treatment options. Until those studies are performed, the care of frail cardiac surgery patients may be best provided by high-volume surgical centers with expertise in the management of frail patients.

Is the contemporary care of the older persons with acute coronary syndrome evidence-based?

Globally, ischaemic heart disease is the leading cause of death, with a higher mortality burden amongst older adults. Although advancing age is associated with a higher risk of adverse outcomes following acute coronary syndrome (ACS), older patients are less likely to receive evidence-based medications and coronary angiography. Guideline recommendations for managing ACS are often based on studies that exclude older patients, and more contemporary trials have been underpowered and produced inconsistent findings. There is also limited evidence for how frailty and comorbidity should influence management decisions. This review focuses on the current evidence base for the medical and percutaneous management of ACS in older patients and highlights the distinct need to enrol older patients with ACS into well-powered, large-scale randomized trials.

Survival and Prognostic Factors After Carotid Artery Stenting in Patients with Concomitant Coronary Disease

AIM: The aim of the study was to analyze the prognostic factors in patients after carotid artery stenting (CAS). METHODS: In 329 patients after CAS, the median survival (MS) and overall survival (OS) were calculated for a follow-up period of 2–101 months. All patients underwent coronary angiography before carotid stenting and, if indicated, coronary revascularization. Four groups of factors were analyzed: Carotid disease, coronary artery disease (CAD), underlying cardiac pathology, and concomitant diseases. RESULTS: MS in all patients was 86 months, OS at 1, 3, 5, and 9 years was - 94%, 85%, 73%, and 51%, respectively. Event free survival was 85 months. Log Rank-Mantel-Cox analysis demonstrated significantly reduced MS in 21 tested factors, most of them related to CAD. Two-step multifactorial Cox regression analysis defined only 7 of them as independent prognostic factors for the survival of patients after CAS: Left main stenosis, complete revascularization, late myocardial infarction, stroke, age over 70 years, valvular disease, and carotid score. CONCLUSION: Survival of patients after CAS is limited mainly by CAD and underlying cardiac pathology. Staged revascularization treatment strategy may improve the prognosis and survival of patients with both carotid and coronary disease.

Ethical Challenges of Nonreading Older Adult Women's Autonomy in Receiving Percutaneous Coronary Intervention Under Familial Paternalism in Taiwan

In the context of familial paternalism in Taiwan, nonreading older adult women (NOAWs) may passively disengage from treatment and submit to the decisions of their families. The purposes of this case study were to examine the ethical conflicts regarding the autonomy of hospitalized NOAWs receiving percutaneous coronary intervention in a cultural environment of familial paternalism and to propose a theoretical framework based on a literature review to resolve the ethical challenges specific to this cultural context. The proposed framework "Nursing advocacy model for engaging NOAWs with their medical treatment" was established on the basis of relational ethics, nursing advocacy, and shared decision making. Our argument does not question traditional Chinese cultural values. Instead, we advocate for NOAWs to engage with their treatment, express their preferences, and communicate with their families in a decision-making process that incorporates mutual respect and understanding within the context of Chinese culture.

Health Inequality Among Older Adults with Percutaneous Coronary Intervention and Universal Health Coverage in Japan

This study aimed to comprehensively evaluate whether income affects long-term health outcomes for older patients who underwent percutaneous coronary intervention (PCI) provided by a universal health coverage system. Data were from the Latter Stage Elderly Healthcare Insurance database in Fukuoka Prefecture, Japan. A total of 5625 individuals aged ≥65 years who underwent PCI in 2014-2016 were included. Cox proportional hazards models were used to assess the association between income status and the incidence of health outcomes. With a median follow-up of 1095 days, 554 acute myocardial infarction (AMI) cases, 1075 stroke cases, 1690 repeat revascularization cases, and 1094 deaths were observed. Risk of all-cause mortality decreased significantly with increasing income level in both unadjusted and adjusted Cox regression models. Patients in the low-income level had a significantly higher rate of AMI (log-rank P = 0.003), stroke (log-rank P = 0.039), and all-cause mortality (log-rank P = 0.001) compared with patients in the high-income level. Observed rates for repeat revascularization also were high in the first year after PCI. In the Japanese universal health setting, low-income patients had a comparatively higher mortality risk after PCI. Poor long-term outcomes might be attributed to patients' baseline characteristics rather than treatment processes.

Non-ST elevation acute coronary syndromes; clinical landscape, management strategy and in-hospital outcomes: an age perspective

Background

As the elderly represent a substantial proportion of medical care beneficiaries, and there is limited data about age disparity in emerging countries, this study sought to investigate the impact of age on the management in patients with non-ST elevation acute coronary syndromes (NSTE-ACS).

Results

Two hundred patients with NSTE-ACS enrolled prospectively, patients’ data, pharmacotherapy, management strategy as well timing to catheterization were documented. Patients grouped into ≥ 65 years versus < 65 years; 32.5% were ≥ 65-year-old. The older group presented as high GRACE risk (Global Registry of Acute Coronary Events) (67.7% versus 15.6%). Elderly patients were less likely to be referred for catheterization compared with younger counterparts (55.4% versus 76.3%, p = 0.003). Within low risk class patients, none of the elderly versus 9.33% of younger patients were catheterized within 2 h; in the same line, none of the elderly versus 16% of younger patients were catheterized within 24 h. Alternatively, at high risk class, 6.81% of the elderly and none of the younger patients were catheterized within 2 h. On the univariate analysis of variables to predict invasive strategy, presence of history of prior IHD, diabetes, absent in-hospital acute heart failure or atrial fibrillation/flutter, higher haemoglobin and lower creatinine levels predicted the use of invasive strategy, while on multivariate analysis, acute heart failure (95% CI − 0.38 to − 0.41, p = 0.01), lower haemoglobin (95% CI 0.002–0.07, p = 0.03), and atrial fibrillation/flutter (95% CI − 0.48 to − 0.02, p = 0.03) predicted conservative strategy. The elderly were more likely to have acute heart failure (32.3% versus 14.8%, p = 0.004), same as stroke (3.1% versus none, p = 0.04).

Conclusions

Less-invasive strategy used in the elderly with NSTE-ACS compared with younger counterparts, yet age was not a predictor of catheterization underuse on multivariate analysis. It is crucial to bridge the age gap in the healthcare system in setting of ACS management by grasping the attention of decision makers and emphasizing on the adherence of healthcare providers to the guidelines to improve cardiovascular care and outcomes.

ST-elevation myocardial infarction in nonagenarians: A nationwide analysis of trends and outcomes in the United States

OBJECTIVE

To assess ST elevation myocardial infarction (STEMI) trends and outcomes in nonagenarians undergoing primary percutaneous coronary intervention (pPCI) compared to medical management.

BACKGROUND

Although nonagenarians (age greater than 90 years) represent the fast-growing age decade of the US population, limited evidence is available regarding trends and outcomes of treatment strategies for STEMI in this population cohort.

METHODS

We performed a retrospective analysis using the National Inpatient Sample (NIS) database to identify nonagenarians presenting with STEMI and treated with either pPCI or medical management. In-hospital mortality, in-hospital complications, length of stay and in-hospital costs were analyzed.

RESULTS

Between 2010-2017, 41,042 STEMI hospitalizations were identified in nonagenarians, of which 11, 155 (27.2%) included pPCI whereas 29, 887 (72.8%) included medical management. STEMI hospitalizations among nonagenarians decreased over the study period. Overall unadjusted in-hospital mortality was 21.6%, and the hospitalizations that included pPCI had significantly lower mortality compared to the medical management (13.6% vs. 24.5%, p < .001). After adjusting for baseline characteristics, hospitalizations that included pPCI had 42.1% lower odds of in-hospital mortality (adjusted OR: 0.58, 95% CI: 0.50 to 0.67, p < .001). Altogether, in-hospital cardiac, bleeding and vascular complications, length of stay and in-hospital costs were higher in pPCI hospitalizations.

CONCLUSION

In nonagenarians, STEMI mortality is high, but pPCI is associated with superior outcomes compared to medical management alone. Therefore, pPCI can be considered an acceptable treatment strategy in this population.

Impact of coronary angioplasty in elderly patients with non-ST-segment elevation myocardial infarction

BACKGROUND

As treatment of coronary artery disease improved over the last years, management of elder patients remained a matter of debate since this age group has been underrepresented in most trials. The study aimed to evaluate a population of patients with ≥ 85 years old with non-ST-segment elevation myocardial infarction (NSTEMI) and compare the prognosis according to coronary revascularization execution.

METHODS

We retrospectively studied 324 patients included in a national multicenter registry between October 2010 and October 2018, who underwent coronary angiography and had at least one stenosis ≥ 50%.

RESULTS

In this population, 73.1% of the patients underwent percutaneous coronary intervention (PCI) and 26.9% of the patients underwent optimized medical treatment (OMT). The OMT group had more past history of diabetes, stroke and dementia. On coronary angiography, the PCI group used more often the femoral artery access and single-vessel lesions were also more common. Three-vessel disease was more common in the OMT group. During hospitalization, there were more major bleeding events and death in the PCI group. During the one-year follow-up, there were no significant differences in all-cause mortality rate.

CONCLUSIONS

Very old patients with NSTEMI submitted to OMT had more comorbidities and more three-vessel disease, factors that could have influenced the therapeutic decision. Patients undergoing PCI had more in-hospital major bleeding events and mortality, with no significant differences after one year.
