RESUMEN
BACKGROUND: Non-vitamin K oral anticoagulants have become the standard therapy for preventing stroke and ischemic thromboembolism in most patients with atrial fibrillation (AF). The effectiveness and safety of non-vitamin K oral anticoagulants in patients on hemodialysis is not well known. METHODS: From June 2017 through May 2022, AXADIA-AFNET 8 (Compare Apixaban and Vitamin K Antagonists in Patients With Atrial Fibrillation and End-Stage Kidney Disease), an investigator-initiated PROBE (prospective randomized open blinded end point) outcome assessment trial, randomized patients with AF on chronic hemodialysis to either apixaban (2.5 mg BID) or the vitamin K antagonist (VKA) phenprocoumon (international normalized ratio, 2.0 to 3.0). The composite primary safety outcome was defined by a first event of major bleeding, clinically relevant nonmajor bleeding, or all-cause death. The primary efficacy outcome was a composite of ischemic stroke, all-cause death, myocardial infarction, and deep vein thrombosis or pulmonary embolism. Our hypothesis was that apixaban is noninferior to VKA. RESULTS: Thirty-nine sites randomized 97 patients (30% women; mean age 75 years; mean CHA2DS2-VASc [congestive heart failure, hypertension, age ≥75 years, diabetes, stroke or transient ischemic attack, vascular disease, age 65 to 74 years, female sex] score, 4.5; baseline characteristics balanced between groups): 48 to apixaban and 49 to VKA. The median follow-up time was 429 days (range, 37 to 1370) versus 506 days (range, 101 to 1379), respectively. Adherence to apixaban was >80% in 44 of 48 patients; the median time in therapeutic range on VKA was 50.7%. Composite primary safety outcome events occurred in 22 patients (45.8%) on apixaban and in 25 patients (51.0%) on VKA (hazard ratio, 0.93 [95% CI, 0.53-1.65]; Pnoninferiority=0.157). Composite primary efficacy outcome events occurred in 10 patients (20.8%) on apixaban and in 15 patients (30.6%) on VKA (P=0.51; log rank). There were no significant differences regarding individual outcomes (all-cause mortality, 18.8% versus 24.5%; major bleeding, 10.4% versus 12.2%; and myocardial infarction, 4.2% versus 6.1%, respectively). CONCLUSIONS: In this randomized trial comparing apixaban and VKA in patients with AF on hemodialysis with long follow-up, no differences were observed in safety or efficacy outcomes. Even on oral anticoagulation, patients with AF on hemodialysis remain at high risk of cardiovascular events. Larger randomized trials are needed to determine the optimal anticoagulation regimen for patients with AF on hemodialysis. REGISTRATION: URL: https://www.

BACKGROUND: Significant age and sex differences have been reported at each stage of the stroke pathway, from risk factors to outcomes. However, there is some uncertainty in previous studies with regard to the role of potential confounders and selection bias. Therefore, using German nationwide administrative data, we aimed to determine the magnitude and direction of trends in age- or sex-specific differences with respect to admission rates, risk factors, and acute treatments of ischemic and hemorrhagic stroke. METHODS: We obtained and analyzed data from the Research Data Centres of the Federal Statistical Office for the years 2010 to 2020 with regard to all acute stroke hospitalizations, risk factors, treatments, and in-hospital mortality, stratified by sex and stroke subtype. This database provides a complete national-level census of stroke hospitalizations combined with population census counts. All hospitalized patients ≥15 years with an acute stroke (diagnosis code: I60-64) were included in the analysis. RESULTS: Over the 11-year study period, there were 3â 375â 157 stroke events; 51.2% (n=1â 728â 954) occurred in men. There were higher rates of stroke admissions in men compared with women for both ischemic (378.1 versus 346.7/100â 000 population) and hemorrhagic subtypes (75.6 versus 65.5/100â 000 population) across all age groups. The incidence of ischemic stroke admissions peaked in 2016 among women (354.0/100â 000 population) and in 2017 among men (395.8/100â 000 population), followed by a consistent decline from 2018 onward. There was a recent decline in hemorrhagic stroke admissions observed for both sexes, reaching its nadir in 2020 (68.9/100â 000 for men; 59.5/100â 000 for women). Female sex was associated with in-hospital mortality for both ischemic (adjusted odds ratio, 1.11 [1.09-1.12]; P<0.001) and hemorrhagic stroke (adjusted odds ratio, 1.18 [95% CI, 1.16-1.20]; P<0.001). CONCLUSIONS: Despite improvements in stroke prevention and treatment pathways in the past decade, sex-specific differences remain with regard to hospitalization rates, risk factors, and mortality. Better understanding the mechanisms for these differences may allow us to develop a sex-stratified approach to stroke care.

BACKGROUND: Atherosclerotic cardiovascular disease (ASCVD) is the most common cause of death in Europe. Although the 2019 European Society of Cardiology/European Atherosclerosis Society Guidelines for the management of dyslipidaemias claim a target low-density lipoprotein cholesterol (LDL-C) value of <55 mg/dL for very high-risk patients by use of lipid-lowering therapy (LLT) and lifestyle adaptations, the target level achievement is not satisfactory. We examined LLT use in ASCVD patients exceeding LDL-C target levels at admission and its adaptations at discharge. METHODS AND RESULTS: Between January 2017 and February 2020, 1091 patients with LDL-C >100 mg/dL and ASCVD defined as diagnosis of angina pectoris (AP, n = 179), acute myocardial infarction (AMI, n = 317), chronic ischemic heart disease (CHD, n = 195), or peripheral artery disease (PAD, n = 400) were extracted from hospital records. LLT use on admission and discharge as well as recommendations on lifestyle and nutrition were analysed. On admission, 51% of the patients were not taking LLT. At discharge, 91% were prescribed statins and 87% were advised on lifestyle adaptation and/or pharmacological treatment. High-intensity statin use at discharge was present in 63% of the AP-group, 92% of the AMI-group, 62% of the CHD-group and 71% of the PAD-group. Ezetimibe was present in 16% and proprotein convertase subtilisin/kexin 9 inhibitors (PCSK9i) in 1%. However, of those on high-intensity statin, 25% remained on insufficient statin dosage. CONCLUSION: Switch to high-intensity statins and use of ezetimibe and PCSK9i was low in chronic ASCVD patients. Even though statin intake was high in high-risk patients, target levels were still not reached.

Background: Peripheral artery disease (PAD) frequently leads to hospital admission. Sex related differences in in-patient care are a current matter of debate. Patients and methods: Data were provided from the German national in-patient sample provided by the Federal Bureau of Statistics (DESTATIS). Trends on risk profiles, therapeutic procedures, and outcomes were evaluated from 2014 until 2019 stratified by sex and PAD severity. Results: Two-thirds of an annual >191,000 PAD in-patient cases applied to male sex. Chronic limb-threatening ischemia (CLTI) was recorded in 49.6% of male and 55.2% of female cases (2019). CLTI was as a major risk factor of in-hospital amputation (OR 229) and death (OR 10.5), whereas endovascular revascularisation (EVR) with drug-coated devices were associated with decreased risk of in-hospital amputation (OR 0.52; all p<0.001). EVR applied in 47% of CLTI cases compared to 71% in intermittent claudication (IC) irrespective of sex. In-hospital mortality was 4.3% in male vs. 4.8% in female CLTI cases, minor amputations 18.4% vs. 10.9%, and major amputation 7.5% vs. 6.0%, respectively (data 2019; all p<0.001). After adjustment, female sex was associated with lower risk of amputation (OR 0.63) and death (OR 0.96) during in-patient stay. Conclusions: Male PAD patients were twice as likely to be admitted for in-patient treatment despite equal PAD prevalence in the general population. Among in-patient cases, supply with invasive therapy did not relevantly differ by sex, however is strongly reduced in CLTI. CLTI is a major risk factor of adverse short-term outcomes, whereas female sex was associated with lower risk of in-patient amputation and/or death.

OBJECTIVE: Chronic limb threatening ischaemia (CLTI) has a devastating prognosis with high rates of lower limb amputation (LLA) and deaths. This is an illustration of contemporary management and the long term fate of patients after ischaemic LLA, particularly with respect to sex, using real world data. METHODS: This was a multisectoral cross sectional and longitudinal analysis of health claims data from the largest German health insurance database (AOK). Data of 39 796 propensity score matched patients hospitalised for ischaemic LLA between 2010 and 2018 were analysed for cardiovascular comorbidities, treatment, and for subsequent cardiovascular and limb events, with a distinct focus on sex. Matching was performed, to ensure that the rate of major amputations and the age distribution were equal in both groups (in both sexes). An observation period of two years before index and a follow up (FU) period until 2019 were included. RESULTS: Before index amputation, 68% of patients had received any kind of peripheral revascularisation. The use of statins (37.0% vs. 42.6%) and antithrombotic substances (54.9% vs. 61.8%) was lower in women than in men (p < .001). During two year FU, cardiovascular and limb events occurred among women and men as follows: limb re-amputation (26.7% vs. 31.2%), myocardial infarction (10.9% vs. 14.5%), stroke (20.8% vs. 20.7%), and death from any cause (51.0% vs. 53.3%, p < .001 except for stroke). After adjustment for cardiovascular comorbidities and vascular procedures, female sex was associated with a higher probability of death (HR 1.04, 95% CI 1.04 - 1.04). CONCLUSION: Patients undergoing ischaemic LLA still have a poor prognosis marked by high rates of recurrent cardiovascular and limb events resulting in a > 50% mortality rate within two years. The continuous lack of guideline recommended therapies, particularly in women, may be associated with the persisting poor outcome, necessitating urgent further investigation.

BACKGROUND: Cardiovascular disease is often associated with chronic kidney disease (CKD), resulting in an increased risk for poor outcome. We sought to determine short-term mortality and overall survival in ST-elevation myocardial infarction (STEMI) patients with different stages of CKD. METHODS: In our retrospective cohort study with health insurance claims data of the Allgemeine Ortskrankenkasse (AOK), anonymized data of all STEMI patients hospitalized between 2010 and 2017 were analyzed regarding presence and severity of concomitant CKD. RESULTS: A total of 175,187 patients had an index-hospitalisation for STEMI (without CKD: 78.6% patients, CKD stage 1: 0.8%, CKD stage 2: 4.8%, CKD stage 3: 11.7%, CKD stage 4: 2.8%, CKD stage 5: 0.7%, CKD stage 5d: 0.6%). Patients with CKD were older and had more co-morbidities than patients without CKD. With increasing CKD severity, patients received less revascularization therapies (91.2%, 85.9%, 87.0%, 81.8%, 71.7%, 76.9% and 78.6% respectively, p < 0.001). After 1 year, guideline-recommended medications were prescribed less frequently in advanced CKD (83.4%, 79.3%, 81.5%, 74.7%, 65.0%, 59.4% and 53.7%, respectively, p < 0.001). CKD stages 4, 5 and 5d as well as chronic limb threatening ischemia (CLTI) were associated with decreased overall survival [CKD stage 4: hazard ratio (HR) 1.72; 95% CI 1.66-1.78; CKD stage 5: HR 2.55; 95% CI 2.37-2.73; CKD stage 5d: 5.64; 95% CI 5.42-5.86; CLTI: 2.06; 95% CI 1.98-2.13; all p < 0.001]. CONCLUSIONS: CKD is a frequent co-morbidity in patients with STEMI and is associated with a worse prognosis especially in advanced stages. Guideline-recommended therapies in patients with STEMI and CKD are still underused.

AIMS: The prevalence of chronic limb-threatening ischaemia (CLTI) is increasing and available data often derive from cohorts with various selection criteria. In the present study, we included CLTI patients and studied sex-related differences in their risk profile, vascular procedures, and long-term outcome. METHODS AND RESULTS: We analysed 199 953 unselected patients of the largest public health insurance in Germany (AOK: Local healthcare funds), hospitalized between 2010 and 2017 for a main diagnosis of CLTI. A baseline period of 2 years before index hospitalization to assess comorbidities and previous procedures, and a follow-up period until 2018 were included. Female CLTI patients were older (median 81.4 vs. 73.8 years in males; P < 0.001) and more often diagnosed with hypertension, atrial fibrillation, chronic heart failure, and chronic kidney disease. Male patients suffered more frequently from diabetes mellitus, dyslipidaemia, smoking, cerebrovascular disease, and chronic coronary syndrome (all P < 0.001). Within hospitalized CLTI patients, females represent the minority (43% vs. 57%; P < 0.001) and during index hospitalization, women underwent less frequently diagnostic angiographies (67 vs. 70%) and revascularization procedures (61 vs. 65%; both P < 0.001). Moreover, women received less frequently guideline-recommended drugs like statins (35 vs. 43%) and antithrombotic therapy (48 vs. 53%; both P < 0.001) at baseline. Interestingly, after including age and comorbidities in a Cox regression analysis, female sex was associated with increased overall-survival (OS) [hazard ratio (HR) 0.95; 95% confidence interval (CI) 0.94-0.96] and amputation-free survival (AFS) (HR 0.84; 95% CI 0.83-0.85; both P < 0.001). CONCLUSION: Female patients with CLTI were older, underwent less often vascular procedures, and received less frequently guideline-recommended medication. Nevertheless, female sex was independently associated with better OS and AFS during follow-up.

Background: The quality of vascular care has significantly improved in part by the expansion of endovascular techniques for the treatment of symptomatic peripheral artery disease (PAD) in recent years. In Germany these are primarily provided by the three disciplines of vascular surgery, angiology, and interventional radiology (IR). However, the relative contribute of angiologists to the total number of cases performed is unknown. Patients and methods: In the present study, we analysed the respective contribution of vascular surgery, angiology, and IR to the delivery of endovascular revascularisations in symptomatic PAD in Germany based on the legally mandatory quality reports representative for the reporting year 2018. Results: Vascular surgery is the most common speciality reporting procedures in German hospitals (n=579; 25.1%), followed by IR (n=264; 11.5%), angiology (n=189; 8.2%) and cardiology (n=17; 0.7%). The combination of vascular surgery and IR was reported in 202 (8.8%), vascular surgery and angiology in 167 (7.2%) and angiology and IR in 65 (2.8%) hospitals, and 63 (2.7%) hospitals reported the combination of all three disciplines. Not every department performed catheter interventions. The analysis of procedures per centre revealed that angiology centres provided the highest numbers for both basic procedures and more complex techniques such as atherectomy, rotational thrombectomy, lithoplasty, selective thrombolysis or the use of re-entry devices. In total, angiology centres provided 24.4% of the total procedures or 23.9% of the so-called basic procedures as a surrogate for patient numbers. Conclusions: While each of the disciplines contribute significantly to the endovascular procedures, angiology centres perform more procedures per centre and more complex procedures than the other disciplines highlighting the important quantitative and qualitative contribution of angiology specialists to the care of vascular patients. The inpatient catheter interventional care of patients with PAD is still too rarely carried out in a multi-disciplinary manner in Germany.

AIM OF THE STUDY: The aim of our study was to analyse sex-specific differences in diagnosis and treatment of patients with lower extremity artery disease (LEAD) at Rutherford stage (RF) 1-3, based on secondary data. Furthermore, we focussed on the influence of the biological sex on short- and long-term outcome. METHODS: The GenderVasc project is carried out in cooperation with the AOK Research Institute (WIdO). As data basis, anonymized routine data from all insured patients of the AOK were used. All patients hospitalized due to a main diagnosis of LEAD at RF 1-3 were included and in addition to the multisectoral cross-sectional analysis, longitudinal analysis (follow-up of up to 10 years) of the health claims data was performed and evaluated. RESULTS: Our secondary data analysis of 42,197 patients with intermittent claudication (IC, LEAD at RF 1-3) showed that male patients were more often hospitalized due to LEAD, while women were older at time-point of index hospitalisation (female: 72.6 vs. male: 66.4 years). Fewer vascular procedures (diagnostic angiography and revascularisation) were carried out in females. Moreover, the prescription of guideline-recommended medications (statins and antithrombotic therapy) was lower in women compared to men. Multivariable Cox regression showed, after adjusting for age, cardiovascular risk profile and performed vascular procedure, that female sex was protective with respect to overall survival and progression of LEAD (progress to chronic limb-threatening ischemia or ischemic amputation). CONCLUSION: In Germany, female LEAD patients were older and less likely to receive guideline-recommended therapy, while female sex is protective in terms of overall survival and progression of LEAD. The extent to which increased age or the presence of other comorbidities influence the decision for or against a vascular procedure can only be assumed from a secondary data analysis. Furthermore, the prescription of drugs in multimorbid patients is challenging and the compliance of the patients with prescribed medication intake is not part of our analysis. Nevertheless, targeted analysis, as in the GenderVasc project, are urgently needed to identify and describe differences in the medical care between the sexes.

Background: Sex-related differences may influence the outcome of endovascular revascularization (EVR) in patients with lower extremity arterial disease (LEAD) even under optimized healthcare supply. Patients and methods: LEAD patients who underwent EVR at the Department of Cardiology I - Coronary and Peripheral Vascular Disease, Heart Failure, University Hospital Muenster, Germany between 2014 and 2016 were included into the retrospective study. Detailed information on risk factors and co-morbidities, medication, LEAD related measures, and interventional parameters were assessed. Outcome defined as technical success rate, complications, and mortality was analyzed up to 12 months follow-up. Results: In total, 165 female and 437 male LEAD patients were included. Women and men presented with comparable severity of LEAD in terms of critical limb threatening ischemia (46.2%), wound status (34.9%), and amputation rate (9.6%, all n.s.) at index. Intake of platelet inhibitors (65.8% female vs. 70.0% male), oral anticoagulants (21.3% vs. 25.4%), and statins (65.6% vs. 76.0%) was observed less frequently in female patients. Against the background of high technical success (85%), in-hospital death (0.8%), severe adverse cardiac (MCE; 1.7%), and limb events (MALE; 6.1%) occurred at low rates in either sex. Adjusted long-term mortality was not affected by patients' sex (female HR 0.755; p=0.312). Conclusions: Despite critical LEAD stages in every second patient, EVR was performed safe with high technical success rates in female and male patients. Long-term outcomes were observed at comparatively low rates in both sexes at the specialized vascular center. During aftercare, supply with statin therapy turned out improvable particularly in female LEAD patients.

BACKGROUND: Peripheral arterial occlusive disease (PAOD) is an atherosclerotic vascular disease with high morbidity and mortality. A consistent medication-based secondary prevention is part of the essential and evidence-based treatment of PAOD. The aim of this study was to ascertain the status quo of medicinal secondary prevention based on submitted prescriptions. METHODS: In the time period from 2014 to 2017 patients with a confirmed PAOD coding (I70.2-/I73.9-) were identified based on secondary data of the Association of Statutory Health Insurance Physicians Westphalia-Lippe (KVWL). The prescriptions submitted with respect to platelet inhibitors, oral anticoagulants, lipid lowering therapy (LLT) and angiotensin-converting enzyme (ACE) inhibitors in the fourth quarter year after diagnosis coding were collated. RESULTS: In the diagnosis period 2014/2015 a total of 238,397 patients had PAOD in the catchment area of the KVWL. The proportion of submitted prescriptions in the fourth quarter year after diagnosis was 25.9% for LLT, 13.6% for acetylsalicylic acid, 4.5% for clopidogrel, 5.5% for vitamin K antagonists (VKA), 3.5% for non-vitamin Kdependent oral anticoagulants (NOAC) and 26.8% for ACE inhibitors. Over the course of the 3 years (nâ¯= 241,375 patients with PAOD 2016/2017) the proportion of submitted prescriptions for all substances except VKA increased (pâ¯< 0.001), whereby the largest relative increase was noted for NOAC (relative increase of 81.7%). CONCLUSION: The guideline-conform medicinal secondary prevention in patients with PAOD in Germany is still in need of improvement. A consistent implementation of evidence-based medicinal secondary prevention harbors a great potential for improvement of the overall prognosis in patients with PAOD.

Background: Patients with chronic critical limb-threatening ischemia (CLTI) are at high risk of amputation and death. Despite the general recommendation for revascularization in CTLI in the guidelines, the underlying evidence for such a recommendation is limited. The aim of our study was to assess the outcome of patients with CLTI depending on the use of revascularization in a retrospective real-world cohort. Patients and methods: Administrative data of the largest German Health insurance (BARMER GEK) were provided for all patients that were hospitalized for the treatment of CLTI Rutherford category (RF) 5 and 6 between 2009 and 2011. Patients were followed-up until December 31st, 2012 for limb amputation and death in relation to whether patients did (Rx +) or did not have (Rx -) revascularization during index-hospitalization. Results: We identified 15,314 patients with CLTI at RF5 (n = 6,908 (45.1%)) and RF6 (n = 8,406 (54.9%)), thereof 7,651 (50.0%) underwent revascularization (Rx +) and 7,663 (50.0%) were treated conservatively (Rx -). During follow-up (mean 647 days; 95% CI 640-654 days) limb amputation (46.5% Rx- vs. 40.6% Rx+, P < 0.001) and overall mortality (48.2% Rx- vs. 42.6% Rx+, P < 0.001) were significantly lower in the subgroup Rx+. Conclusions: In a real-world setting, only half of CLTI were revascularized during the in-hospital treatment. Though, revascularization was associated with significantly better observed short- and long-term outcome. These data do not allow causal conclusion due to lack of data on the underlying reason for applied or withheld revascularization and therefore may involve a relevant selection bias.

Chronic kidney disease (CKD) is associated with increased cardiovascular morbidity and mortality but there are few studies available about atrial fibrillation, the most frequent arrhythmia in CKD, and the applied treatment. Based on the prospective German Competence NETwork on Atrial Fibrillation, data of 3138 patients with atrial fibrillation were analyzed and categorized by their estimated glomerular filtration rate (stages 1-3 and 4 plus 5). With advanced CKD, significantly more patients suffered from a more severe form of atrial fibrillation. Despite significantly higher CHADS2 scores in advanced CKD, oral anticoagulation was not prescribed more frequently while antiarrhythmic drugs and catheter ablations were used significantly less often, in contrast to more pacemaker implantations. However, in multivariate hierarchical logistic regression analyses of in-hospital treatments and complications, only hemorrhages and pacemaker implantations turned out to be independently and significantly associated with higher CKD stages. This nationwide study shows that patients with CKD and atrial fibrillation suffer from a markedly higher comorbidity. Thus, while CKD patients have received cardioversions, ablations, antiarrhythmic, or anticoagulation drugs significantly less often in their history, current treatments were not different if adjusted for multiple comorbidities. This might indicate an improvement in the often reported therapeutic nihilism in CKD.

Chronic kidney disease (CKD) is associated with an increased risk of heart failure (HF). Elevated plasma concentrations of soluble Flt-1 (sFlt-1) have been linked to cardiovascular disease in CKD patients, but whether sFlt-1 contributes to HF in CKD is still unknown. To provide evidence that concludes a pathophysiological role of sFlt-1 in CKD-associated HF, we measured plasma sFlt-1 concentrations in 586 patients with angiographically documented coronary artery disease and renal function classified according to estimated glomerular filtration rate (eGFR). sFlt-1 concentrations correlated negatively with eGFR and were associated with signs of heart failure, based on New York Heart Association functional class and reduced left ventricular ejection fraction (LVEF), and early mortality. Additionally, rats treated with recombinant sFlt-1 showed a 15 % reduction in LVEF and a 29 % reduction in cardiac output compared with control rats. High sFlt-1 concentrations were associated with a 15 % reduction in heart capillary density (number of vessels/cardiomyocyte) and a 24 % reduction in myocardial blood volume. Electron microscopy and histological analysis revealed mitochondrial damage and interstitial fibrosis in the hearts of sFlt-1-treated, but not control rats. In 5/6-nephrectomised rats, an animal model of CKD, sFlt-1 antagonism with recombinant VEGF121 preserved heart microvasculature and significantly improved heart function. Overall, these findings suggest that a component of cardiovascular risk in CKD patients could be directly attributed to sFlt-1. Assessment of patients with CKD confirmed that sFlt-1 concentrations were inversely correlated with renal function, while studies in rats suggested that sFlt-1 may link microvascular disease with HF in CKD.

Background: Specifically young women are at risk for a poor outcome after ST-elevation myocardial infarction (STEMI). We aimed to investigate sex- and age-specific differences in outcome and associate these results with adherence to a guideline-directed optimal medical therapy (OMT). Methods: Administrative insurance data (≈26 million insured) were screened for patients aged 18-60 years with STEMI. Patient demographics, details on in-hospital treatment, adherence to OMT and its effect on mortality were assessed. Adherence to OMT was analyzed using multistate models and an association of those with death was fitted using multivariable Cox regression models with time-dependent co-variables. Results: Overall, 59,401 patients (19.3% women), median age 52 (interquartile range 48, 56) presented with STEMI. Female sex was associated with a poor outcome early after STEMI (90-day mortality: odds ratio 1.22, 95% confidence interval (CI) 1.12-1.32, p < 0.001). Overall survival was reduced in women compared to same-aged men. The ten-year survival rate was 19.7% (18.1-21.2%) versus 19.6% (18.9-20.4%) in men (p < 0.001). Although long-term drug adherence was low, its intake was associated with a better outcome. Specifically younger women showed a markedly lower mortality when on OMT (hazard ratio (HR) 0.22 (95% CI 0.19-0.26) versus HR 0.31 (95% CI 0.28-0.33) in men, pint < 0.001). Conclusions: Specifically young women were at risk for a poor outcome in the early phase after STEMI. Although long-term adherence to OMT was low, it was generally associated with a lower mortality, specifically in women. Our findings emphasize on early and long-term preventive measures in all patients after STEMI.
RESUMEN
BACKGROUND: During the past 10 years, chronic kidney disease (CKD) has been recognized as a major global health problem. Factors leading to decreased renal function are closely related to cardiovascular disease and vice versa. Cardiovascular morbidity and mortality are substantially increased in patients with CKD, even in those with only mild or moderate renal impairment. A better understanding of pathogenesis, risk factors, and genetic conditions is strongly required for more specific treatment strategies in CKD because until now, knowledge is very limited. METHODS: The German CAD-REF registry is a prospective observational multicenter national registry. It aims at including >3,300 white patients with angiographically documented coronary artery disease (coronary artery disease [CAD]; ≥50% stenosis in at least 1 coronary artery) being enrolled at 32 centers and assigned to 6 different groups according to their estimated glomerular filtration rate and/or proteinuria. Baseline characteristics, treatment data, and biomaterial including serum, plasma, urine, and DNA samples are collected. Follow-ups are performed at 6, 12, 24, 36, 48, and 60 months. CONCLUSIONS: The CAD-REF registry will establish one of the largest ethnically homogeneous cohorts, to date, of clinically and angiographically well-characterized patients with CAD who have all stages of CKD. This approach offers great opportunities for an improved understanding of the underlying pathophysiologic mechanism and clinical impact of CKD in patients with CAD, especially including the identification of clinically relevant risk factors and (genetic and other bio-) markers as a basis to ameliorate future treatment strategies.

BACKGROUND: The impact of the encounter between coronary heart disease (CHD) and cancer, and in particular hematologic malignancies (HM), remains poorly understood. OBJECTIVE: The aim of this analysis was to clarify how HM affects the prognosis of acute coronary syndrome (ACS). We analyzed German health insurance data from 11 regional Ortskrankenkassen (AOK) of patients hospitalized for ACS between January 2010 and December 2018, matched by age, sex and all comorbidities for short- and long-term survival and major adverse cardiac events (MACE). RESULTS: Of 439,716 patients with ACS, 2104 (0.5%) also had an HM. Myelodysplastic/myeloproliferative disorders (27.7%), lymphocytic leukemias (24.8%), and multiple myeloma (22.4%) predominated. These patients were about 6 years older (78 vs. 72 years *). They had an ST-segment elevation myocardial infarction (STEMI, 18.2 vs. 34.9% *) less often and more often had a non-STEMI (NSTEMI, 81.8 vs. 65.1% *). With the exception of dyslipidemia, these patients had more concomitant and previous cardiovascular disease and a worse NYHA stage. They were less likely to undergo coronary angiography (65.3 vs. 71.6% *) and percutaneous coronary intervention (PCI, 44.3 vs. 52.0% *), although the number of bleeding events was not relevantly increased (p = 0.22). After adjustment for the patients' risk profile, the HM was associated with reduced long-term survival. However, this was not true for short-term survival. Here, there was no difference in the STEMI patients, * p < 0.001. CONCLUSION: Survival in ACS and HM is significantly lower, possibly due to the avoidance of PCI because of a perceived increased risk of bleeding.
RESUMEN
Background: Survivors of myocardial infarction have an elevated risk of long-term mortality. We sought to evaluate guideline-directed medical treatment and its impact on long-term mortality in survivors of ST-elevation myocardial infarction (STEMI) according to their chronic kidney disease (CKD) stage. Methods: Using German health insurance claims data, 157 663 hospitalized survivors of STEMI were identified. Regarding different CKD stages, we retrospectively analysed the filled prescriptions of platelet inhibitors (PAI)/oral anticoagulation, statins, beta-blocker and angiotensin-converting enzyme inhibitors/angiotensin II type 1 receptor antagonists (ACE-I/AT1-A) and their association with long-term mortality. Results: Prescription rates for all four guideline-directed drugs were highest in patients without or with mild CKD and lowest in patients on dialysis. They dropped from 73.4% to 39.2% in patients without CKD and from 47.1% to 29% in patients on dialysis within the 5-year follow-up period. Mortality rates were dramatically increased in patients with CKD compared with patients without CKD (5-year mortality: no CKD, 16.7%; CKD stage 3, 47.1%; CKD stage 5d, 69.7%). Filled prescriptions of at least one drug class [one drug: hazard ratio (HR) 0.70, 95% confidence interval (95% CI) 0.66-0.74; four drugs: HR 0.28, 95% CI 0.27-0.30; P < .001 for both] as well as the distinct drug classes (statins: HR 0.55, 95% CI 0.54-0.56; ACE-I/AT1-A: HR 0.68, 95% CI 0.67-0.70; beta-blocker: HR 0.87, 95% CI 0.85-0.90; PAI/oral anticoagulation: HR 0.97, 95% CI 0.95-1.00; all P < .05) improved long-term mortality. Conclusions: An improved long-term guideline-recommended drug therapy after STEMI regardless of renal impairment might lead to beneficial effects on long-term mortality.
RESUMEN
BACKGROUND AND AIMS: Acute myocardial infarction (AMI) is the leading cause of death worldwide. Outcome has improved during the last decades due to secondary prevention and widespread coronary interventions, but recent studies still show sex differences and insufficient drug adherence. We aimed to determine differences in the treatment strategies and outcomes between women and men with ST-elevation myocardial infarction (STEMI) in Germany. METHODS: From the Federal Association of the Local Health Insurance Funds (Allgemeine Ortskrankenkasse), 175,187 patients were identified who were hospitalized due to STEMI in Germany between January 1, 2010 and December 31, 2017. RESULTS: Compared to men, women were older (median 76 vs. 64 years) and had more often diabetes, hypertension, chronic heart failure, and chronic kidney disease (all p <0.001). Women suffered from higher rates of in-hospital complications such as bleeding (9.3 vs. 6.6%), longer hospitalizations (12.2 vs. 11.7 days) and were less likely to undergo percutaneous coronary intervention (75.5 vs. 85.2%). After adjustment for patient's risk profile, female sex was associated with decreased overall survival (HR 1.02, 95% confidence interval (CI) 1.00-1.04; p=0.036). Notably, more men received all four guideline-recommended drugs after STEMI (women 65.7% vs. men 69.8% after 90 days; p <0.001). With increasing number of prescribed drugs, patients benefit even more. This concerned both sexes, but was more pronounced in men (with 4 prescribed drugs: women HR 0.52, 95%CI 0.50-0.55; men HR 0.48, 95% CI 0.47-0.50, pint = 0.014). CONCLUSIONS: In a contemporary nationwide analysis, women with STEMI were older, had more comorbidities, underwent revascularization less often and had an increased risk for major complications as well as overall survival. Guideline-recommended drug therapy was applied less frequently in women although associated with an improved overall-survival.

Lower extremity artery disease (LEAD) affects millions of elderly patients and is associated with elevated cardiovascular morbidity and mortality. Risk factor modification, including the therapy of dyslipidaemia, is mandatory to reduce cardiovascular event rates and to improve survival rates. However, only a minority achieve the recommended low-density lipoprotein cholesterol (LDL-C) target level < 55 mg/dL, according to the current ESC/EAS guidelines on the treatment of dyslipidaemia. This study elucidated the implementation of the lipid-lowering guideline recommendations of 400 LEAD patients with LDL-C > 100 mg/dL and their adherence to treatment adjustment during follow-up. Despite a sustained statin prescription in 93% of the patients, including 77% with high-intensity statins at follow-up, only 18% achieved the target level. Ezetimibe appeared in 21% and LDL-C goals were reached significantly more often with combination therapy. Recurrent revascularization appeared more often (28%) than coronary artery or cerebrovascular disease progression (14%) and 7% died. Despite the frequent use of high-intensity statins and expandable rates of ezetimibe, the progression of cardiovascular events remained inevitable. Only 18% of the patients had received recommendations on lifestyle modification, including dietary adaptations, which is key for a holistic approach to risk factor control. Thus, efforts for both pharmacological and behavioral strategies are needed to improve clinical outcomes and survival rates.
