The impact of patient-reported frailty on cardiovascular outcomes in elderly patients after non-ST-acute coronary syndrome. Int J Cardiol 2024; 405:131940. [PMID: 38458385 DOI: 10.1016/j.ijcard.2024.131940] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 02/20/2024] [Accepted: 03/05/2024] [Indexed: 03/10/2024]
Abstract
BACKGROUND As life expectancy increases, the population of older individuals with coronary artery disease and frailty is growing. We aimed to assess the impact of patient-reported frailty on the treatment and prognosis of elderly early survivors of non-ST-elevation acute coronary syndrome (NSTE-ACS). METHODS Frailty data were obtained from two prospective trials, POPular Age and the POPular Age Registry, which both assessed elderly NSTE-ACS patients. Frailty was assessed one month after admission with the Groningen Frailty Indicator (GFI) and was defined as a GFI-score of 4 or higher. In these early survivors of NSTE-ACS, we assessed differences in treatment and 1-year outcomes between frail and non-frail patients, considering major adverse cardiovascular events (MACE, including cardiovascular mortality, myocardial infarction, and stroke) and major bleeding. RESULTS The total study population consisted of 2192 NSTE-ACS patients, aged ≥70 years. The GFI-score was available in 1320 patients (79 ± 5 years, 37% women), of whom 712 (54%) were considered frail. Frail patients were at higher risk for MACE than non-frail patients (9.7% vs. 5.1%, adjusted hazard ratio [HR] 1.57, 95% confidence interval [CI] 1.01-2.43, p = 0.04), but not for major bleeding (3.7% vs. 2.8%, adjusted HR 1.23, 95% CI 0.65-2.32, p = 0.53). Cubic spline analysis showed a gradual increase of the risk for clinical outcomes with higher GFI-scores. CONCLUSIONS In elderly NSTE-ACS patients who survived 1-month follow-up, patient-reported frailty was independently associated with a higher risk for 1-year MACE, but not with major bleeding. These findings emphasize the importance of frailty screening for risk stratification in elderly NSTE-ACS patients.

Abstract
OBJECTIVE We describe the current treatment of elderly patients with non-ST-elevation myocardial infarction (NSTEMI) enrolled in a national registry. METHODS The POPular AGE registry is a prospective, multicentre study of patients ≥ 75 years of age presenting with NSTEMI, performed in the Netherlands. Management was at the discretion of the treating physician. Cardiovascular events consisted of cardiovascular death, myocardial infarction and ischaemic stroke. Bleeding was classified according to the Bleeding Academic Research Consortium (BARC) criteria. RESULTS A total of 646 patients were enrolled between August 2016 and May 2018. Median age was 81 (IQR 77-84) years and 58% were male. Overall, 75% underwent coronary angiography, 40% percutaneous coronary intervention, and 11% coronary artery bypass grafting, while 49.8% received pharmacological therapy only. At discharge, dual antiplatelet therapy (aspirin and P2Y12 inhibitor) was prescribed to 56.7%, and 27.4% received oral anticoagulation plus at least one antiplatelet agent. At 1‑year follow-up, cardiovascular death, myocardial infarction or stroke had occurred in 13.6% and major bleeding (BARC 3 and 5) in 3.9% of patients. The risk of both cardiovascular events and major bleeding was highest during the 1st month. However, cardiovascular risk was three times as high as bleeding risk in this elderly population, both after 1 month and after 1 year. CONCLUSIONS In this national registry of elderly patients with NSTEMI, the majority are treated according to current European Society of Cardiology guidelines. Both the cardiovascular and bleeding risk are highest during the 1st month after NSTEMI. However, the cardiovascular risk was three times as high as the bleeding risk.

Conservative versus Invasive Strategy in Elderly Patients with Non-ST-Elevation Myocardial Infarction: Insights from the International POPular Age Registry. J Clin Med 2023; 12:5450. [PMID: 37685517 PMCID: PMC10487667 DOI: 10.3390/jcm12175450] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 08/15/2023] [Accepted: 08/18/2023] [Indexed: 09/10/2023] Open
Abstract
This registry assessed the impact of conservative and invasive strategies on major adverse clinical events (MACE) in elderly patients with non-ST-elevation myocardial infarction (NSTEMI). Patients aged ≥75 years with NSTEMI were prospectively registered from European centers and followed up for one year. Outcomes were compared between conservative and invasive groups in the overall population and a propensity score-matched (PSM) cohort. MACE included cardiovascular death, acute coronary syndrome, and stroke. The study included 1190 patients (median age 80 years, 43% female). CAG was performed in 67% (N = 798), with two-thirds undergoing revascularization. Conservatively treated patients had higher baseline risk. After propensity score matching, 319 patient pairs were successfully matched. MACE occurred more frequently in the conservative group (total population 20% vs. 12%, adjHR 0.53, 95% CI 0.37-0.77, p = 0.001), remaining significant in the PSM cohort (18% vs. 12%, adjHR 0.50, 95% CI 0.31-0.81, p = 0.004). In conclusion, an early invasive strategy was associated with benefits over conservative management in elderly patients with NSTEMI. Risk factors associated with ischemia and bleeding should guide strategy selection rather than solely relying on age.

Abstract
Abstract
Background/Introduction
Elderly constitute a large though specific group of patients presenting with non-ST elevation myocardial infarction (NSTEMI), as they are at higher risk of adverse cardiovascular events, as well as treatment-related complications. However as they underrepresented in clinical trials, the optimal management strategy for older patients with NSTEMI remains unclear.
Purpose
The aim of this registry was to capture the medical and invasive treatment of elderly NSTEMI patients, find predictors for major adverse cardiovascular events (MACE) and estimate the impact of invasive management and revascularisation.
Methods
The POPular AGE registry is a prospective, observational multicentre study of patients ≥75 years of age presenting with NSTEMI at multiple sites in the Netherlands, United Kingdom and Austria. Management was at the discretion of the treating physician. MACE consisted of cardiovascular death, acute coronary syndrome (ACS) and stroke. Net adverse clinical events (NACE) was defined as composite of all-cause death, ACS, definite stent thrombosis, stroke, or major bleeding (Bleeding Academic Research Consortium [BARC] bleeding 3 or 5). The population was stratified into an invasively treated group defined as patients who underwent coronary angiography (CAG); and a conservatively-treated group with patients who received medical treatment only. The duration of follow-up was one year. Clinical variables were assessed for their predictive value for MACE and bleeding by means of a Cox proportional hazard regression.
Results
The total study population consisted of 1190 elderly patients with NSTEMI (median age 80 years [IQR 77–84], 43% female). Invasive treatment with CAG was performed in 67% of the population, of which 49% underwent PCI and 14% coronary artery bypass grafting (CABG). At discharge, the majority of patients (55%) were treated with dual antiplatelet therapy (DAPT). MACE occurred in 15% and major bleeding occurred in 5% of the total population. Age (HR 1.06, 95% CI 1.03–1.09), diabetes mellitus (HR 1.62, 95% CI 1.16–2.24), reduced LVEF (<50%) (HR 1.51, 95% CI 1.03–2.20), Killip class (HR 1.58, 95% CI 1.07–2.33) and electrocardiogram (ECG) changes at admission (HR 1.67, 95% CI 1.20–2.31) were predictors for MACE. MACE occurred more frequently in conservatively-treated than invasively-treated patients (20% vs. 12%, HR 0.52, 95% CI 0.38–0.70, p<0.001). Revascularization with PCI or CABG was associated with lower risk of MACE (PCI; HR 0.47, 95% CI 0.30–0.75, p=0.001 and CABG; HR 0.31, 95% CI 0.13– 0.73, p=0.008).
Conclusions
In this prospective registry of NSTEMI patients of ≥75 years, MACE and major bleeding were frequent. Age, diabetes mellitus, reduced LVEF, Killip class and ECG changes at admission were independent predictors for MACE. Although subject to selection bias, undergoing CAG and revascularisation, when indicated, were associated with better outcomes.

Cost-effectiveness of clopidogrel versus ticagrelor in patients of 70 years or older with non-ST-elevation acute coronary syndrome. Eur Heart J 2022.

Abstract
Abstract
Background/Introduction
In older patients with non-ST-elevation acute coronary syndrome (NSTEMI) the POPular AGE trial clopidogrel showed superiority to ticagrelor in reducing bleeding risk and non-inferiority in net clinical benefit (all-cause death, myocardial infarction, stroke, and PLATelet inhibition and patient Outcomes; major or minor bleeding).
Purpose
The aim of this analysis was to estimate the long-term cost-effectiveness of clopidogrel compared to ticagrelor in these older patients with NSTEMI and to address the impact on quality of life by both treatment strategies.
Methods
A 1-year decision tree based on the POPular AGE trial in combination with a lifelong Markov model was developed to compare clopidogrel with ticagrelor in terms of clinical outcomes, costs and quality-adjusted life years (QALYs) in elderly patients (above 70 year) with NSTEMI. Cost-effectiveness was assessed from a Dutch healthcare system perspective. Events rates and utility data observed in the POPular AGE trial were combined with lifetime projections to evaluate cost and effects for a fictional cohort of 1000 patients. Deterministic, probabilistic sensitivity analyses and several scenario analyses were performed. The several scenario's included different time horizons, identical prices for P2Y12-inhibitors, different health utilities in the clopidogrel and ticagrelor arm and a prolonged duration of bleeding disutility.
Results
Treatment with clopidogrel instead of ticagrelor led to a cost saving of €1,482,775 (€1,483 per patient) and a decrease of 10,96 quality-adjusted life years (QALY's) (0.011 QALY per patient) in the fictional cohort. In an alternative base case with equal distribution over health states in the first year based on the non-inferiority of the POPular AGE trial, treatment with clopidogrel was the dominant strategy both cost saving and increasing QALY's. In all scenario analyses, treatment with clopidogrel was cost saving. In the scenario with different health utilities in the clopidogrel and ticagrelor arm, the distinct average reported health utilities in both treatment arms were used. In this scenario clopidogrel was the dominant strategy.
Conclusion
This analysis shows that clopidogrel is a cost-saving alternative to ticagrelor in elderly patients after NSTEMI, with a very small negative effect on QALY's. It supports the conclusion of the POPular AGE trial to regard clopidogrel as a favourable alternative to ticagrelor in the elderly patient after a NSTEMI.

Abstract
OBJECTIVE The POPular AGE trial showed that clopidogrel significantly reduced bleeding risk compared with ticagrelor without any signs of an increase in thrombotic events. The aim of this analysis was to estimate the long-term cost-effectiveness of clopidogrel compared with ticagrelor in these patients aged 70 years or older with non-ST-elevation acute coronary syndrome (NSTE-ACS). METHODS AND RESULTS A 1-year decision tree based on the POPular AGE trial in combination with a lifelong Markov model was developed to compare clopidogrel with ticagrelor in terms of clinical outcomes, costs, and quality-adjusted life years (QALYs) in elderly patients (above 70 year) with NSTE-ACS. Cost-effectiveness was assessed from a Dutch healthcare system perspective. Events rates and utility data observed in the POPular AGE trial were combined with lifetime projections to evaluate costs and effects for a fictional cohort of 1000 patients. Treatment with clopidogrel instead of ticagrelor led to a cost saving of €1484 575 (€1485 per patient) and a decrease of 10.96 QALYs (0.011 QALY per patient) in the fictional cohort. In an alternative base case with equal distribution over health states in the first year, treatment with clopidogrel led to an increase in QALYs. In all scenario analyses, treatment with clopidogrel was cost-saving. CONCLUSION Clopidogrel is a cost-saving alternative to ticagrelor in elderly patients after NSTE-ACS, though regarding overall cost-effectiveness clopidogrel was not superior to ticagrelor, as it resulted in a small negative effect on QALYs. However, based on the results of the alternative base case and clinical outcomes of the POPular AGE trial, clopidogrel could be a reasonable alternative to ticagrelor for elderly NSTE-ACS patients with a higher bleeding risk.

Safety considerations with the use of platelet inhibitors for elderly patients with non-ST- elevation acute coronary syndrome. Expert Opin Drug Saf 2021; 20:1545-1552.

Abstract
Introduction: Dual antiplatelet therapy (DAPT) is standard treatment for patients with acute coronary syndrome (ACS). This includes lifelong aspirin combined with a P2Y12 inhibitor for 1 year. The indication for one of the P2Y12 inhibitors (clopidogrel, prasugrel, ticagrelor) is dependent on the treatment strategy; whether patients undergo coronary angiography or are treated medically only. Tailoring antiplatelet therapy to the risk profile of the individual patient is of specific importance to the older patient.Areas covered: In this review, we discuss dual antiplatelet therapy in elderly patients with ACS. We present the options to tailor antiplatelet therapy based on platelet function testing, CYP2C19 genotyping and patients' thrombotic and bleeding risk. Finally, we discuss alternatives for dual antiplatelet therapy.Expert opinion: DAPT in elderly patients with ACS should consist of aspirin with clopidogrel or ticagrelor. Weighing patients' thrombotic and bleeding risk, based on clinical judgment or with use of specific risk scores, is probably the most convenient method to individualize antiplatelet therapy; however, CYP2C19 genotyping can also be used. In elderly patients with an increased bleeding risk, clopidogrel is a safe and effective alternative to ticagrelor. An alternative to 12 months DAPT could be ticagrelor monotherapy after a short period of DAPT.

Clopidogrel in noncarriers of CYP2C19 loss-of-function alleles versus ticagrelor in elderly patients with acute coronary syndrome: A pre-specified sub analysis from the POPular Genetics and POPular Age trials CYP2C19 alleles in elderly patients. Int J Cardiol 2021; 334:10-17. [PMID: 33887342 DOI: 10.1016/j.ijcard.2021.04.029] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2021] [Revised: 04/09/2021] [Accepted: 04/16/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND Patients with acute coronary syndrome (ACS) who are carrying CYP2C19 loss-of-function alleles derive less benefit from clopidogrel treatment. Despite this, in elderly patients, clopidogrel might be preferred over more potent P2Y12 inhibitors due to a lower bleeding risk. Whether CYP2C19 genotype-guided antiplatelet treatment in the elderly could be of benefit has not been studied specifically. METHODS Patients aged 70 years and older with known CYP2C19*2 and *3 genotype were identified from the POPular Genetics and POPular Age trials. Noncarriers of loss-of-function alleles treated with clopidogrel were compared to patients, irrespective of CYP2C19 genotype, treated with ticagrelor and to clopidogrel treated carriers of loss-of-function alleles. We assessed net clinical benefit (all-cause death, myocardial infarction, stroke and Platelet Inhibition and Patient Outcomes (PLATO) major bleeding), atherothrombotic outcomes (cardiovascular death, myocardial infarction, stroke) and bleeding outcomes (PLATO major and minor bleeding). RESULTS A total of 991 patients were assessed. There was no significant difference in net clinical benefit (17.2% vs. 15.1%, adjusted hazard ratio (adjHR) 1.05, 95% confidence interval (CI) 0.77-1.44), atherothrombotic outcomes (9.7% vs. 9.2%, adjHR 1.00, 95%CI 0.66-1.50), and bleeding outcomes (17.7% vs. 19.8%, adjHR 0.80, 95%CI 0.62-1.12) between clopidogrel in noncarriers of loss-of-function alleles and ticagrelor respectively. CONCLUSION In ACS patients aged 70 years and older, there was no significant difference in net clinical benefit and atherothrombotic outcomes between noncarriers of a loss-of-function allele treated with clopidogrel and patients treated with ticagrelor. The bleeding rate was numerically; though not statistically significant, lower in patients using clopidogrel.

Rationale and Design of the Future Optimal Research and Care Evaluation in Patients with Acute Coronary Syndrome (FORCE-ACS) Registry: Towards "Personalized Medicine" in Daily Clinical Practice. J Clin Med 2020; 9:jcm9103173.

Abstract
Diagnostic and treatment strategies for acute coronary syndrome have improved dramatically over the past few decades, but mortality and recurrent myocardial infarction rates remain high. An aging population with increasing co-morbidities heralds new clinical challenges. Therefore, in order to evaluate and improve current treatment strategies, detailed information on clinical presentation, treatment and follow-up in real-world patients is needed. The Future Optimal Research and Care Evaluation in patients with Acute Coronary Syndrome (FORCE-ACS) registry (ClinicalTrials.gov Identifier: NCT03823547) is a multi-center, prospective real-world registry of patients admitted with (suspected) acute coronary syndrome. Both non-interventional and interventional cardiac centers in different regions of the Netherlands are currently participating. Patients are treated according to local protocols, enabling the evaluation of different diagnostic and treatment strategies used in daily practice. Data collection is performed using electronic medical records and quality-of-life questionnaires, which are sent 1, 12, 24 and 36 months after initial admission. Major end points are all-cause mortality, myocardial infarction, stent thrombosis, stroke, revascularization and all bleeding requiring medical attention. Invasive therapy, antithrombotic therapy including patient-tailored strategies, such as the use of risk scores, pharmacogenetic guided antiplatelet therapy and patient reported outcome measures are monitored. The FORCE-ACS registry provides insight into numerous aspects of the (quality of) care for acute coronary syndrome patients.

Abstract
BACKGROUND Approximately 15% of saphenous vein grafts (SVGs) occlude during the first year after coronary artery bypass graft surgery (CABG) despite aspirin use. The POPular CABG trial (The Effect of Ticagrelor on Saphenous Vein Graft Patency in Patients Undergoing Coronary Artery Bypass Grafting Surgery) investigated whether ticagrelor added to standard aspirin improves SVG patency at 1 year after CABG. METHODS In this investigator-initiated, randomized, double-blind, placebo-controlled, multicenter trial, patients with ≥1 SVGs were randomly assigned (1:1) after CABG to ticagrelor or placebo added to standard aspirin (80 mg or 100 mg). The primary outcome was SVG occlusion at 1 year, assessed with coronary computed tomography angiography, in all patients that had primary outcome imaging available. A generalized estimating equation model was used to perform the primary analysis per SVG. The secondary outcome was 1-year SVG failure, which was a composite of SVG occlusion, SVG revascularization, myocardial infarction in myocardial territory supplied by a SVG, or sudden death. RESULTS Among 499 randomly assigned patients, the mean age was 67.9±8.3 years, 87.1% were male, the indication for CABG was acute coronary syndrome in 31.3%, and 95.2% of procedures used cardiopulmonary bypass. Primary outcome imaging was available in 220 patients in the ticagrelor group and 223 patients in the placebo group. The SVG occlusion rate in the ticagrelor group was 10.5% (51 of 484 SVGs) versus 9.1% in the placebo group (43 of 470 SVGs), odds ratio, 1.29 [95% CI, 0.73-2.30]; P=0.38. SVG failure occurred in 35 (14.2%) patients in the ticagrelor group versus 29 (11.6%) patients in the placebo group (odds ratio, 1.22 [95% CI, 0.72-2.05]). CONCLUSIONS In this randomized, placebo-controlled trial, the addition of ticagrelor to standard aspirin did not reduce SVG occlusion at 1 year after CABG.

Abstract
Background We sought to compare long-term follow-up of coronary artery bypass grafting (CABG) with percutaneous coronary intervention (PCI) in elderly patients with left main or multivessel disease, hypothesising that completeness of revascularisation and severity of coronary artery disease are predictors of adverse outcomes. Methods Patients aged ≥75 years with multivessel disease or left main disease who underwent PCI or CABG between 2012–2016 were included in this retrospective cohort study. Baseline characteristics from the index procedure were collected. Severity of coronary artery disease and completeness of revascularisation were assessed. Primary outcome was all-cause mortality, in addition we captured major adverse cardiac and cerebral events, bleedings, recurrent angina and new onset atrial fibrillation. Results A total of 597 patients were included. Median follow-up was 4 years (interquartile range 2.8–5.3 years). At baseline, patients in the PCI group more often had a previous medical history of CABG and more frequently underwent an urgent procedure compared with patients in the CABG group. Mortality at 5‑year follow-up was significantly higher in patients who underwent PCI compared with CABG (39.9% vs 25.4%, p < 0.001). Furthermore, acute coronary syndrome (ACS), repeat revascularisation and recurrent angina occurred more frequently after PCI, while occurrence of bleedings and new onset atrial fibrillation were more frequent after CABG. Neither completeness of revascularisation nor severity of coronary artery disease was a predictor for any of the outcomes. Conclusion Long-term mortality was higher in elderly patients with multivessel disease undergoing PCI compared with CABG. In addition, patients undergoing PCI had a higher risk of ACS, repeat revascularisation and recurrent angina.

Abstract
Elderly patients with an acute coronary syndrome are underrepresented in randomised controlled trials. Neither the European Society of Cardiology nor the American Heart Association/American College of Cardiology acute coronary syndrome guidelines provide specific recommendations for elderly patients. However, elderly patients are at higher thrombotic and bleeding risk compared with younger patients leading to difficulties in choosing the optimal treatment. In this review, we discuss the uncertainties we encounter in treating elderly patients with non-ST-elevation acute coronary syndrome and suggest treatment options based on the existing literature.
