Ten-year mortality after treating obstructive coronary atherosclerosis with contemporary stents in patients with or without concomitant peripheral arterial disease.

BACKGROUND AND AIMS: Previous studies in percutaneous coronary intervention (PCI) patients showed a higher 3-year adverse event risk, including all-cause mortality, in those with concomitant peripheral arterial disease (PADs). Ten-year data of mortality and causes of death are scarce. This analysis assessed PCI patients, treated with contemporary drug-eluting stents, the impact of concomitant PADs on very long-term mortality, and causes of death. METHODS: We assessed PCI all-comers from our center who participated in the TWENTE and DUTCH PEERS trials (clinicaltrials.gov:NCT01066650, NCT01331707), comparing patients with versus without PADs. Life status was checked in the Dutch Personal Records Database; causes of death were obtained from medical records. RESULTS: Of 2705 study patients, 668 (24.7%) died during follow-up: 88/212 (41.5%) patients with PADs and 580/2493 (23.1%) without PADs. In PADs patients, the 10-year rate of all-cause mortality was about twice as high as in patients without PADs (41.5% vs.23.1%, HR: 2.05, 95%-CI: 1.64-2.57, p<0.001). For both groups, the rates of patients dying from various causes of death were: cardiac (14.1% vs.6.8%), vascular (2.8% vs. 1.1%), non-cardiovascular (17.4% vs. 9.8%), and unclear causes (7.1% vs. 5.3%), without a statistically significant between-group difference. When multivariate analysis was adjusted for between-group differences in cardiovascular risk profile, PADs remained predictor of all-cause mortality (adjusted HR: 1.38, 95%-CI: 1.08-1.75, p=0.01). CONCLUSIONS: The 10-year all-cause mortality rate in PCI patients with concomitant PADs was almost twice as high as in those without PADs. Age and other traditional cardiovascular risk factors were higher in patients with PADs, but after correction for these confounders PADs still accounted for almost 40% increase in mortality.

Use of loop diuretics in patients with chronic heart failure: an observational overview.

INTRODUCTION: This study aimed to evaluate the use and dose of loop diuretics (LDs) across the entire ejection fraction (EF) spectrum in a large, 'real-world' cohort of chronic heart failure (HF) patients. METHODS: A total of 10 366 patients with chronic HF from 34 Dutch outpatient HF clinics were analysed regarding diuretic use and diuretic dose. Data regarding daily diuretic dose were stratified by furosemide dose equivalent (FDE)>80 mg or ≤80 mg. Multivariable logistic regression models were used to assess the association between diuretic dose and clinical features. RESULTS: In this cohort, 8512 (82.1%) patients used diuretics, of which 8179 (96.1%) used LDs. LD use was highest among HF with reduced EF (HFrEF) patients (81.1%) followed by HF with mild-reduced EF (76.1%) and HF with preserved ejection fraction EF (73.8%, p<0.001). Among all LDs users, the median FDE was 40 mg (IQR: 40-80). The results of the multivariable analysis showed that New York Heart Association classes III and IV and diabetes mellitus were one of the strongest determinants of an FDE >80 mg, across all HF categories. Renal impairment was associated with a higher FDE across the entire EF spectrum. CONCLUSION: In this large registry of real-world HF patients, LD use was highest among HFrEF patients. Advanced symptoms, diabetes mellitus and worse renal function were significantly associated with a higher diuretic dose regardless of left ventricular ejection fraction.

Blood Culture-negative Endocarditis Caused by Tropheryma whipplei: Whipple's endocarditis.

CASE DESCRIPTION: A 67-year-old man was admitted with progressive heart failure due to blood culture-negative endocarditis of the aortic valve. Urgent aortic valve replacement was needed. Polymerase chain reaction (PCR) testing of samples of the explanted aortic valve revealed Tropheryma whipplei. The patient received ceftriaxone, followed by long-term co-trimoxazole. Recent arthralgia may have been a diagnostic clue. CONCLUSION: Whipple's endocarditis should be considered in patients with arthralgia and blood culture-negative endocarditis (BCNIE). LEARNING POINTS: Whipple's endocarditis should be considered in patients with symptoms of arthralgia and blood culture-negative endocarditis (BCNIE).Serum polymerase chain reaction is the main diagnostic test.Both physician awareness and multidisciplinary management by regional endocarditis teams are recommended strategies to provide optimal patient care.

Age differences in contemporary treatment of patients with chronic heart failure and reduced ejection fraction.

BACKGROUND: Elderly patients are underrepresented in clinical trials but comprise the majority of heart failure patients. Data on age-specific use of heart failure therapy are limited. The European Society of Cardiology heart failure guidelines provide no age-specific treatment recommendations. We investigated practice-based heart failure management in a large registry at heart failure outpatient clinics. DESIGN AND METHODS: We studied 8351 heart failure with reduced ejection fraction patients at 34 Dutch outpatient clinics between 2013 and 2016. The mean age was 72.3 ± 11.8 years and we divided age into three categories: less than 60 years (13.9%); 60-74 years (36.0%); and 75 years and over (50.2%). RESULTS: Elderly heart failure with reduced ejection fraction patients (≥75 years) received significantly fewer beta-blockers (77.8% vs. 84.2%), renin-angiotensin system inhibitors (75.2% vs. 89.7%), mineralocorticoid receptor antagonists (50.6% vs. 59.6%) and ivabradine (2.9% vs. 9.3%), but significantly more diuretics (88.1% vs. 72.6%) compared to patients aged less than 60 years (Pfor all trends < 0.01). Moreover, the prescribed target dosages were significantly lower in elderly patients. Also, implantable cardioverter defibrillator (18.9% vs. 44.1%) and cardiac resynchronisation therapy device (14.6% vs. 16.7%) implantation rates were significantly lower in elderly patients. A similar trend in drug prescription was observed in patients with heart failure with mid-range ejection fraction as in heart failure with reduced ejection fraction. CONCLUSION: With increasing age, heart failure with reduced ejection fraction patients less often received guideline-recommended medication prescriptions and also in a lower dosage. In addition, a lower percentage of implantable cardioverter defibrillator and cardiac resynchronisation therapy device implantation in elderly patients was observed.

Resultados de los stents Resolute Integrity y Promus Element en el infarto de miocardio: análisis del ensayo aleatorizado DUTCH PEERS (TWENTE II ) / Outcome after myocardial infarction treated with Resolute Integrity and Promus Element stents: insights from the DUTCH PEERS (TWENTE II) randomized trial

Introducción y objetivos: En el infarto agudo de miocardio (IAM), los nuevos stents farmacoactivos (SFA) de alta liberación de fármacos pueden ser de especial utilidad, ya que su diseño flexible podría reducir los traumatismos inducidos por el dispositivo en la lesión culpable. El objetivo del estudio es evaluar la seguridad y la eficacia de las intervenciones coronarias percutáneas con 2 nuevos SFA con recubrimiento de polímero duradero en pacientes con IAM. Métodos: El ensayo multicéntrico prospectivo y aleatorizado DUTCH PEERS (TWENTE II) compara los stents Resolute Integrity y Promus Element en 1.811 pacientes consecutivos no seleccionados (all-comers); a 817 (45,1%) de ellos se los trató por un IAM con o sin elevación del segmento ST y se dispuso de un seguimiento de 2 años del 99,9% de los casos. El objetivo clínico principal es el fallo del vaso diana (FVD), que consiste en la combinación de muerte cardiaca, infarto de miocardio relacionado con el vaso diana y revascularización del vaso diana. Resultados: De los 817 pacientes tratados por un IAM, 421 (51,5%) recibieron un stent Resolute Integrity y 396 (48,5%), un Promus Element. A los 2 años de seguimiento, las tasas de FVD (el 7,4 frente al 6,1%; p = 0,45), revascularización de la lesión diana (el 3,1 frente al 2,8%; p = 0,79) y trombosis del stent definitiva (el 1,0 frente al 0,5%; p = 0,69) fueron bajas en los 2 grupos de stents. En consonancia con estos resultados obtenidos en el conjunto de los pacientes con IAM, los resultados observados con los 2 SFA fueron favorables y similares con ambos dispositivos en 370 pacientes con IAM con elevación del segmento ST (FVD, el 5,1 frente al 4,9%; p = 0,81) y 447 pacientes con IAM sin elevación del segmento ST (FVD, el 9,0 frente al 7,5%; p = 0,56). Conclusiones: Los stents Resolute Integrity y Promus Element fueron seguros y eficaces en el tratamiento de pacientes con IAM. Los datos de seguimiento a 2 años subrayan la seguridad de emplear estos dispositivos en este contexto clínico específico (AU)

Introduction and objectives: In acute myocardial infarction (MI), novel highly deliverable drug-eluting stents (DES) may be particularly valuable as their flexible stent designs might reduce device-induced traumas to culprit lesions. The aim of the study was to assess the safety and efficacy of percutaneous coronary interventions with 2 novel durable polymer-coated DES in patients with acute MI. Methods: The prospective, randomized DUTCH PEERS (TWENTE II) multicenter trial compares Resolute Integrity and Promus Element stents in 1811 all-comer patients, of whom 817 (45.1%) were treated for ST-segment elevation MI or non—ST-segment elevation MI and the 2-year outcome is available in 99.9%. The primary clinical endpoint is target vessel failure (TVF), a composite of cardiac death, target vessel related MI, or target vessel revascularization. Results: Of all 817 patients treated for acute MI, 421 (51.5%) were treated with Resolute Integrity and 396 (48.5%) with Promus Element stents. At the 2-year follow-up, the rates of TVF (7.4% vs 6.1%; P = .45), target lesion revascularization (3.1% vs 2.8%; P = .79), and definite stent thrombosis (1.0% vs 0.5%; P = .69) were low for both stent groups. Consistent with these findings in all patients with acute MI, outcomes for the 2 DES were favorable and similar in both, with 370 patients with ST-segment elevation MI (TVF, 5.1% vs 4.9%; P = .81) and 447 patients with non—ST-segment elevation MI (TVF, 9.0% vs 7.5%; P = .56). Conclusions: Resolute Integrity and Promus Element stents were both safe and efficacious in treating patients with acute MI. The present 2-year follow-up data underline the safety of using these devices in this particular clinical setting (AU)
