Background-Randomized trials that studied clinical outcomes after percutaneous coronary intervention (PCI) with bare metal stenting versus coronary artery bypass grafting (CABG) are underpowered to properly assess safety end points like death, stroke, and myocardial infarction. Pooling data from randomized controlled trials increases the statistical power and allows better assessment of the treatment effect in high-risk subgroups. Methods and Results-We performed a pooled analysis of 3051 patients in 4 randomized trials evaluating the relative safety and efficacy of PCI with stenting and CABG at 5 years for the treatment of multivessel coronary artery disease. The primary end point was the composite end point of death, stroke, or myocardial infarction. The secondary end point was the occurrence of major adverse cardiac and cerebrovascular accidents, death, stroke, myocardial infarction, and repeat revascularization. We tested for heterogeneities in treatment effect in patient subgroups. At 5 years, the cumulative incidence of death, myocardial infarction, and stroke was similar in patients randomized to PCI with stenting versus CABG (16.7% versus 16.9%, respectively; hazard ratio, 1.04, 95% confidence interval, 0.86 to 1.27; P = 0.69). Repeat revascularization...

Objectives We evaluated demographic, clinical, and angiographic factors influencing the selection of coronary artery bypass graft (CABG) surgery versus percutaneous coronary intervention (PCI) in diabetic patients with multivessel coronary artery disease (CAD) in the BARI 2D (Bypass Angioplasty Revascularization Investigation in Type 2 Diabetes) trial. Background Factors guiding selection of mode of revascularization for patients with diabetes mellitus and multivessel CAD are not clearly defined. Methods In the BARI 2D trial, the selected revascularization strategy, CABG or PCI, was based on physician discretion, declared independent of randomization to either immediate or deferred revascularization if clinically warranted. We analyzed factors favoring selection of CABG versus PCI in 1,593 diabetic patients with multivessel CAD enrolled between 2001 and 2005. Results Selection of CABG over PCI was declared in 44% of patients and was driven by angiographic factors including triple vessel disease (odds ratio [OR]: 4.43), left anterior descending stenosis >= 70% (OR: 2.86), proximal left anterior descending stenosis >= 50% (OR: 1.78), total occlusion (OR: 2.35), and multiple class C lesions (OR: 2.06) (all p < 0.005). Nonangiographic predictors of CABG included age >= 65 years (OR: 1.43...

Background: Percutaneous coronary intervention (PCI) has increased as the initial revascularization strategy in chronic coronary artery disease. Consequently, more patients undergoing coronary artery bypass grafting (CABG) have history of coronary stent. Objective: Evaluate the impact of previous PCI on in-hospital mortality after CABG in patients with multivessel coronary artery disease. Methods: Between May/2007 and June/2009, 1099 consecutive patients underwent CABG on cardiopulmonary bypass. Patients with no PCI (n=938, 85.3%) were compared with patients with previous PCI (n=161, 14.6%). Logistic regression models and propensity score matching analysis were used to assess the risk-adjusted impact of previous PCI on in-hospital mortality. Results: Both groups were similar, except for the fact that patients with previous PCI were more likely to have unstable angina (16.1% x 9.9%, p=0.019). In-hospital mortality after CABG was higher in patients with previous PCI (9.3% x 5.1%, p=0.034) and it was comparable with EuroSCORE and 2000 Bernstein-Parsonnet risk score. Using multivariate logistic regression analysis, previous PCI emerged as an independent predictor of postoperative in-hospital mortality (odds ratio 1.94, 95% CI 1.02-3.68...

Introdução. A intervenção coronária percutânea (ICP) é um dos tratamentos para pacientes com doença arterial coronária (DAC). Essa intervenção deve ser acompanhada de outras medidas terapêuticas com o intuito de reduzir as incapacidades e o risco de novos eventos coronários; de controlar a progressão da doença; e de melhorar a qualidade de vida. Essas medidas compreendem a prevenção secundária da DAC e estão, principalmente, relacionadas às mudanças no estilo de vida para o manejo de fatores de risco para DAC. O contato por telefone tem sido utilizado por profissionais da área da saúde para o seguimento do paciente e da família no cuidado com diversas condições crônicas, incluindo a DAC. Objetivo. Desenvolver, implementar e avaliar um programa educativo com seguimento por telefone, durante o período de quatro meses após a alta hospitalar, para pacientes submetidos à ICP com o objetivo de melhorar o estado de saúde percebido, a autoeficácia, a adesão aos medicamentos e o estado emocional desses pacientes, bem como comparar desfechos do Programa Educativo com os de serviços de rotina hospitalar. Método. Ensaio clínico controlado e aleatorizado, realizado no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto. A amostra deste estudo foi constituída pelos pacientes submetidos à primeira ICP...

Introdução: Embora a intervenção coronária percutânea esteja associada a baixos índices de complicações, o infarto do miocárdio periprocedimento tem sido apontado como um fator negativo nos resultados clínicos. Os ensaios clínicos randomizados e as revisões sistemáticas recentes confirmaram que uma alta dose de estatina antes da intervenção coronária percutânea eletiva reduz o risco para a ocorrência do infarto do miocárdio periprocedimento. Objetivos: O objetivo desta pesquisa foi aferir a eficácia da pré-administração de uma dose de ataque de rosuvastatina na redução do infarto do miocárdio periprocedimento em pacientes submetidos à intervenção coronária percutânea eletiva com stent coronário. Métodos: De março de 2011 a dezembro de 2013, um total de 528 pacientes portadores de doença coronária estável em uso de estatina (há mais de 7 dias), submetidos à intervenção coronária percutânea eletiva em artéria coronária nativa (e lesão não reestenótica) foram randomizados prospectivamente em único centro, para receberem dose única de ataque de rosuvastatina (40 mg via oral, 2 a 6 horas prévio ao procedimento; grupo rosuvastatina; n=264) versus tratamento padrão (ausência da administração de rosuvastatina; grupo controle; n=264). O objetivo primário foi analisar a incidência intra-hospitalar de infarto do miocárdio periprocedimento (elevação da fração miocárdica da creatina-quinase massa maior que 3 vezes o limite superior do normal). Os objetivos secundários foram analisar a incidência da elevação da fração miocárdica da creatina-quinase massa acima de 1 vez o limite superior do normal e a incidência de eventos adversos graves como infarto agudo do miocárdio com supra desnível do segmento ST...

Background—In the Occluded Artery Trial (OAT), 2201 stable patients with an occluded infarctrelated artery (IRA) were randomized to percutaneous coronary intervention (PCI) or optimal medical treatment alone (MED). There was no difference in the primary endpoint of death, re-MI or heart failure (CHF). We examined the prognostic impact of pre-randomization stress testing. Methods—Stress testing was required by protocol except for patients with single vessel disease and akinesis/dyskinesis of the infarct zone. The presence of severe inducible ischemia was an exclusion criterion for OAT. We compared outcomes based on performance and results of stress testing. Results—598 (27%) patients (297 PCI, 301 MED) underwent stress testing. Radionuclide imaging or stress echocardiography was performed in 40%. Patients who had stress testing were younger (57 vs. 59 years), had higher ejection fractions (49% vs. 47%), and had lower rates of death (7.8% vs. 13.2%), class IV CHF (2.4% vs. 5.5%), and the primary endpoint (13.9% vs. 18.9%) than patients without stress testing (all p<0.01). Mild-moderate ischemia was observed in 40% of patients with stress testing, and was not related to outcomes. Among patients with inducible ischemia, outcomes were similar for PCI and MED (all p>0.1). Conclusions—In OAT...

BACKGROUND: The Occluded Artery Trial (OAT) was a 2,201-patient randomized clinical trial comparing routine stent-based percutaneous coronary intervention (PCI) versus optimal medical therapy alone in stable myocardial infarction (MI) survivors with persistent infarct-related artery occlusion identified day 3 to 28 post MI. Intent-to-treat analysis showed no difference between strategies with respect to the incidence of new class IV congestive heart failure, MI, or death. The influence of PCI failure, procedural hazard, and crossover on trial results has not been reported. METHODS: Study angiograms were analyzed and adjudicated centrally. Factors associated with PCI failure were examined. Time-to-event analysis using the OAT primary outcome was performed by PCI success status. Landmark analysis (up to and beyond 30 days) partitioned early hazard versus late outcome according to treatment received. RESULTS: Percutaneous coronary intervention was adjudicated successful in >87%. Percutaneous coronary intervention failure rates were similar in US and non-US sites, and did not significantly influence outcome at 60 months (hazard ratio for success vs fail 0.79, 99% CI 0.45-1.40, P = .29). Partitioning of early procedural hazard revealed no late benefit for PCI (hazard ratio for PCI success vs medical therapy alone 1.06...

OBJECTIVES: Hyperuricemia is a risk factor for contrast-induced acute kidney injury in patients with chronic kidney disease. This study evaluated the value of hyperuricemia for predicting the risk of contrast-induced acute kidney injury in patients with relatively normal serum creatinine who were undergoing percutaneous coronary interventions. METHODS AND RESULTS: A total of 788 patients with relatively normal baseline serum creatinine (<1.5 mg/dL) undergoing percutaneous coronary intervention were prospectively enrolled and divided into a hyperuricemic group (n = 211) and a normouricemic group (n = 577). Hyperuricemia is defined as a serum uric acid level>7 mg/ dL in males and >6 mg/dL in females. The incidence of contrast-induced acute kidney injury was significantly higher in the hyperuricemic group than in the normouricemic group (8.1% vs. 1.4%, p<0.001). In-hospital mortality and the need for renal replacement therapy were significantly higher in the hyperuricemic group. According to a multivariate analysis (adjusting for potential confounding factors) the odds ratio for contrast-induced acute kidney injury in the hyperuricemic group was 5.38 (95% confidence interval, 1.99-14.58; p = 0.001) compared with the normouricemic group. The other risk factors for contrast-induced acute kidney injury included age >75 years...

OBJECTIVE: To evaluate the effects of percutaneous coronary intervention and thrombolysis after restoration of spontaneous circulation in cardiac arrest patients with ST-elevation myocardial infarction using meta-analysis. METHODS: We performed a meta-analysis of clinical studies indexed in the PUBMED, MEDLINE and EMBASE databases and published between January 1995 and October 2012. In addition, we compared the hospital discharge and neurological recovery rates between the patients who received percutaneous coronary intervention and those who received thrombolysis. RESULTS: Twenty-four studies evaluating the effects of percutaneous coronary intervention or thrombolysis after restoration of spontaneous circulation in cardiac arrest patients with ST-elevation myocardial infarction were included. Seventeen of the 24 studies were used in this meta-analysis. All studies were used to compare percutaneous coronary intervention and thrombolysis. The meta-analysis showed that the rate of hospital discharge improved with both percutaneous coronary intervention (p<0.001) and thrombolysis (p<0.001). We also found that cardiac arrest patients with ST-elevation myocardial infarction who received thrombolysis after restoration of spontaneous circulation did not have decreased hospital discharge (p = 0.543) or neurological recovery rates (p = 0.165) compared with those who received percutaneous coronary intervention. CONCLUSION: In cardiac arrest patients with ST-elevation myocardial infarction who achieved restoration of spontaneous circulation...

OBJECTIVES: Acute ST-segment elevation myocardial infarction patients presenting persistent no-flow after wire insertion have a lower survival rate despite successful mechanical intervention. The neutrophil-to-lymphocyte ratio has been associated with increased mortality and worse clinical outcomes in ST-segment elevation myocardial infarction. We hypothesized that an elevated neutrophil-to-lymphocyte ratio would also be associated with a persistent Thrombolysis In Myocardial Infarction flow grade of 0 after wire insertion in patients undergoing primary percutaneous coronary intervention. METHODS: A total of 644 patients with ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention within 12 hours of symptom onset were included in our study. Blood samples were drawn immediately upon hospital admission. The patients were divided into 3 groups according to their Thrombolysis In Myocardial Infarction flow grade: Thrombolysis In Myocardial Infarction flow grade 0 after wire insertion, Thrombolysis In Myocardial Infarction flow grade 1-3 after wire insertion and Thrombolysis In Myocardial Infarction flow grade 1-3 at baseline. RESULTS: The neutrophil-to-lymphocyte ratio was significantly higher in the group with Thrombolysis In Myocardial Infarction flow grade 0 after wire insertion compared with the group with Thrombolysis In Myocardial Infarction flow grade 1-3 after wire insertion and the group with Thrombolysis In Myocardial Infarction flow grade 1-3 at baseline. The group with Thrombolysis In Myocardial Infarction flow grade 0 after wire insertion also had a significantly higher in-hospital mortality rate. Persistent coronary no-flow after wire insertion was independently associated with the neutrophil-to-lymphocyte ratio. CONCLUSIONS: An increased neutrophil-to-lymphocyte ratio on admission is significantly associated with persistent coronary no-flow after wire insertion in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.

Objectives We sought to assess clinical outcomes of elderly patients (age ≥75 years) undergoing percutaneous coronary intervention (PCI) for acute myocardial infarction (MI) complicated by cardiogenic shock (CS) in a contemporary multicenter PCI registry. Background Although benefits of early PCI have been shown in younger groups, few studies have reported on clinical outcomes in elderly shock patients using current PCI techniques. Methods We analyzed baseline characteristics and procedural and clinical outcomes in 143 consecutive patients presenting with MI and CS who underwent PCI from the Melbourne Interventional Group registry between 2004 and 2007. Results Of the 143 patients, 31.5% (n = 45) were elderly and 68.5% were younger (age <75 years). Elderly patients were more likely to be female (46.7% vs. 22.4%, p < 0.01) and have hypertension (77.8% vs. 46.4%, p < 0.01), previous MI (31.1% vs. 15.5%, p = 0.03), renal failure (24.4% vs. 11.3%, p < 0.05) and multivessel coronary artery disease (93.1% vs. 68.3%, p < 0.01). Stent (86.7% vs. 94.8%, p = 0.09), glycoprotein IIb/IIIa inhibitor (68.9% vs. 65.3%, p = 0.67), and intra-aortic balloon pump (57.8% vs. 58.2%, p = 0.97) use were similar in both groups. In-hospital, 30-day, and 1-year mortality in the elderly group versus the younger group were 42.2% vs. 33.7% (p = 0.32)...

AIMS Percutaneous coronary intervention (PCI) and catheter ablation are well-accepted therapeutic interventions for treatment of coronary artery disease and atrial fibrillation (AF), respectively. We sought to examine temporal trends in the provision of these services over the past decade in Australia. METHODS AND RESULTS A retrospective review of the numbers of PCIs and AF ablations from 2000/01 to 2009/10 was performed on data from three sources: the Australian Institute of Health, Welfare and Aging (AIHW), Medicare Australia database (MA), and local records at a high volume tertiary referral centre (RMH) for AF ablation. Linear regression models were fitted comparing trends in population-adjusted procedural numbers over the 10-year period. There was a 5% per year population-adjusted increment in PCIs over 10 years from both the AIHW and MA sources, respectively (P < 0.001). This was similar to the growth rate of all cardiovascular procedures (AIHW: 5.1 vs. 3.8%/year, P = 0.27). Atrial fibrillation ablations showed a 30.9, 23.2, and 39.8% per year population-adjusted increment over 10 years from the AIHW, MA, and RMH sources respectively (P < 0.001 for all). Growth of AF ablations was significantly higher than PCIs (P < 0.001 for AIHW and MA sources) and all cardiovascular procedures (AIHW: 30.9 vs. 3.8%/year...

Introdução. A dupla antiagregação plaquetária traz benefícios no tratamento do infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMSST). Há variabilidade intra e interindividual no uso do clopidogrel e isso influencia no benefício do seu uso nesse grupo de pacientes. O objetivo desta pesquisa foi avaliar os efeitos de novo antiagregantes plaquetários (prasugrel e ticagrelor) administrados na sala de emergência ("upstream") sobre o resultado angiográfico da angioplastia primária, levando em conta o fluxo coronariano TIMI, o blush miocárdico e a carga de trombo. Métodos. Foi realizado um ensaio clínico, randomizado, cego, com 131 pacientes admitidos com IAMSST. Todos os pacientes receberam ácido acetilsalicílico (AAS). Os pacientes foram randomizados para receber clopidogrel (n=44), prasugrel (n=41) ou ticagrelor (n=46) como dose de ataque ainda na emergência. Todos os pacientes foram submetidos a aspiração manual de trombos. Ao término do procedimento, o resultado angiográfico foi avaliado quanto ao fluxo TIMI, o blush miocárdico e a carga de trombo. Resultados. O fluxo coronariano TIMI >= 1 antes do procedimento foi observado mais frequentemente com o uso de ticagrelor (n = 10, 21,7%) do que com o clopidogrel (n = 1...

Contexte L’occlusion d’une artère du cœur cause un syndrome coronarien aigu (SCA) soit avec une élévation du segment ST (IAMEST) ou sans élévation du segment ST (1). Le traitement des patients avec un IAMEST requiert soit une intervention coronarienne d’urgence (ICP primaire) ou une thérapie fibrinolytique (FL). La thérapie FL peut être administrée soit dans un contexte pré-hospitalier (PHL) ou à l’hôpital. Une prise en charge précoce des patients avec SCA peut être améliorée par un simple indice de risque. Objectifs Les objectifs de cette thèse étaient de : 1) comparer l’ICP primaire et la thérapie FL (2); décrire plusieurs systèmes internationaux de PHL; (3) développer et valider un indice de risque simplifié pour une stratification précoce des patients avec SCA. Méthodes Nous complétons des méta-analyses, de type hiérarchique Bayésiennes portant sur l’effet de la randomisation, d’études randomisées et observationnelles; complétons également un sondage sur des systèmes internationaux de PHL; développons et validons un nouvel indice de risque pour ACS (le C-ACS). Résultats Dans les études observationnelles, l’ICP primaire, comparée à la thérapie FL, est associée à une plus grande réduction de la mortalité à court-terme; mais ce sans bénéfices concluants à long terme. La FL pré-hospitalière peut être administrée par des professionnels de la santé possédant diverses expertises. Le C-ACS a des bonnes propriétés discriminatoires et pourrait être utilisé dans la stratification des patients avec SCA. Conclusion Nous avons comblé plusieurs lacunes importantes au niveau de la connaissance actuelle. Cette thèse de doctorat contribuera à améliorer l’accès à des soins de qualité élevée pour les patients ayant un SCA.; Background Acute occlusion of an artery of the heart results in acute coronary syndromes (ACS)...

We examined the longitudinal changes of VEGF levels after percutaneous coronary intervention for predicting major adverse cardiac events (MACE) in coronary artery disease (CAD) patients. VEGF was measured in 94 CAD patients' serum before revascularization, 1-month and 1-year after. Independently of clinical presentation, patients had lower VEGF concentration than a cohort of healthy subjects (median, IQ: 15.9, 9.0-264 pg/mL versus 419, 212-758 pg/mL; P < 0.001) at baseline. VEGF increased to 1-month (median, IQ: 276, 167-498 pg/mL; P < 0.001) and remained steady to 1-year (median, IQ: 320, 173-497 pg/mL; P < 0.001) approaching control levels. Drug eluting stent apposition and previous medication intake produced a less steep VEGF evolution after intervention (P < 0.05). Baseline VEGF concentration <40.8 pg/mL conveyed increased risk for MACE in a 5-year follow-up. Results reflect a positive role of VEGF in recovery and support its importance in CAD prognosis.

Background: The association of chronic renal insufficiency with outcomes after percutaneous coronary intervention (PCI) in the current era of drug-eluting stents and modern antithrombotic therapy has not been well characterized. Methods and Results: We queried the 2007–2011 Nationwide Inpatient Sample databases to identify all patients aged ≥18 years who underwent PCI. Multivariable logistic regression was used to compare in-hospital outcomes among patients with chronic kidney disease (CKD), patients with end-stage renal disease (ESRD), and those without CKD or ESRD. Of 3 187 404 patients who underwent PCI, 89% had no CKD/ESRD; 8.6% had CKD; and 2.4% had ESRD. Compared to patients with no CKD/ESRD, patients with CKD and patients with ESRD had higher in-hospital mortality (1.4% versus 2.7% versus 4.4%, respectively; adjusted odds ratio for CKD 1.15, 95% CI 1.12 to 1.19, P<0.001; adjusted odds ratio for ESRD 2.29, 95% CI 2.19 to 2.40, P<0.001), higher incidence of postprocedure hemorrhage (3.5% versus 5.4% versus 6.0%, respectively; adjusted odds ratio for CKD 1.21, 95% CI 1.18 to 1.23, P<0.001; adjusted odds ratio for ESRD 1.27, 95% CI 1.23 to 1.32, P<0.001), longer average length of stay (2.9 days versus 5.0 days versus 6.4 days...

As doenças cardíacas estão entre as condições crônicas consideradas como desafio para o setor saúde deste século e, nas próximas décadas, continuarão sendo a principal causa de morte global. Dentre as doenças cardiovasculares, a Doença Arterial Coronariana (DAC) é uma das mais importantes causas de morbimortalidade na população adulta. A Intervenção Coronária Percutânea (ICP) é uma das formas de tratamento da DAC. Deve ser acompanhada de medidas terapêuticas farmacológicas e não farmacológicas com o intuito de controlar a sua progressão e melhorar a qualidade de vida relacionada à saúde (QVRS). Objetivo. Comparar as medidas de QVRS e de sintomas de ansiedade e de depressão um ano após à ICP, de acordo com o tipo de intervenção recebida (rotina do serviço ou programa educativo com seguimento por telefone). Método. Estudo observacional, de delineamento longitudinal no qual acompanhamos a evolução dessas variáveis de interesse em pacientes submetidos à primeira ICP, entre agosto/2011 e junho/2012, atendidos em um hospital universitário do interior do Estado de São Paulo e que participaram de um estudo clínico aleatorizado. No estudo de intervenção, 30 pacientes participaram de um Programa Educativo com seguimento por telefone (grupo intervenção-GI) e outros 30 receberam informações de acordo com a rotina do serviço (grupo controle-GC) antes da realização da ICP. Doze meses após a intervenção...

OBJECTIVES: Hyperuricemia is a risk factor for contrast-induced acute kidney injury in patients with chronic kidney disease. This study evaluated the value of hyperuricemia for predicting the risk of contrast-induced acute kidney injury in patients with relatively normal serum creatinine who were undergoing percutaneous coronary interventions. METHODS AND RESULTS: A total of 788 patients with relatively normal baseline serum creatinine (

Background: Prasugrel is recommended over clopidogrel in poor/intermediate CYP2C19 metabolizers with acute coronary syndrome (ACS) and planned percutaneous coronary intervention (PCI), reducing the risk of ischemic events. CYP2C19 genetic testing can guide antiplatelet therapy in ACS patients. Objective: The purpose of this study was to evaluate the cost-utility of genotype-guided treatment, compared with prasugrel or generic clopidogrel treatment without genotyping, from the US healthcare provider's perspective. Methods: A decision model was developed to project lifetime economic and humanistic burden associated with clinical outcomes (myocardial infarction [MI], stroke and major bleeding) for the three strategies in patients with ACS. Probabilities, costs and age-adjusted quality of life were identified through systematic literature review. Incremental cost-utility ratios (ICURs) were calculated for the treatment strategies, with quality-adjusted life years (QALYs) as the primary effectiveness outcome. Relative risk of developing myocardial infarction and stroke between patients with and without variant CYP2C19 when receiving clopidogrel were estimated to be 1.34 and 3.66, respectively. One-way and probabilistic sensitivity analyses were performed. Results: Clopidogrel cost USD19...

Objectives: We sought to identify predictors of in-hospital and long-term (> 1 year) mortality and major adverse cardiac events (MACE) in elderly patients referred for percutaneous coronary intervention (PCI). Methods: Seventy-three patients (> 80 years) were included. Clinical and interventional characteristics were collected retrospectively. Primary end points were in-hospital and long-term mortality, and a composite of non-fatal myocardial infarction, target vessel revascularization, urgent coronary artery bypass graft surgery, and death (MACE). Results: Eighty-three percent of the patients had acute coronary syndromes, 43% three-vessel disease, and 42% heart failure. In-hospital mortality and MACE were 16.4% and 19%, respectively. Long-term mortality and MACE were 11.3% and 16.4%, respectively. Univariate characteristics associated with in-hospital mortality and MACE were: Killip Class III-IV, heart failure, cardiogenic shock, TIMI 0-2 flow prior and after intervention, diabetes mellitus, contrast nephropathy, and presence of A-V block or atrial fibrillation (AF). Long term predictors for mortality were the presence of heart failure, cardiogenic shock, diabetes mellitus, TIMI flow 0-2 before and after intervention, and A-V block or AF. Conclusion: The identification of the factors previously mentioned may help to predict complications in elderly patients.
