RESUMO
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 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.

Guidelines recommend transesophageal echocardiography (TEE) before cardioversion in thrombogenic arrhythmias when the requirement of ≥ 3 weeks of anticoagulation is not met. Current data to support this approach, especially with direct oral anticoagulants (DOAC), are scarce. We analyzed consecutive elective pre-cardioversion TEE in a high-volume electrophysiology center for the occurrence of left atrial appendage (LAA) thrombi or reduced LAA flow velocity. Possible predictors were recorded and compared in a multivariate logistic regression analysis. Consecutive pre-cardioversion TEE in 512 patients (148 female, median age 69 years) were included. In all patients, indication for TEE was either intake of anticoagulation < 3 weeks before cardioversion or uncertain adherence to the prescribed anticoagulation regimen. Of the 512 TEE, 19 (3.7%) depicted a LAA thrombus. An additional 41 patients (8.0%) showed either a reduced LAA flow velocity (≤ 20 cm/s), LAA sludge, or both. In a multivariate logistic regression analysis, QRS width on admission 12-lead ECG emerged as a possible predictor of LAA thrombus and reduced LAA flow (p = 0.008). Noteworthy, a high CHA2DS2-VASc score was not associated with an increased risk of reduced LAA emptying velocity and LAA thrombi were even found in patients with a CHA2DS2-VASc score of 0 (n = 1) and 1 (n = 1). The presence of LAA thrombus before an elective cardioversion is a rare event in the age of direct oral anticoagulants. However, LAA thrombi occurred even in supposed low-risk individuals according to the CHA2DS2-VASc score. QRS width may aid in identifying patients at risk of reduced LAA flow velocity.

PURPOSE: To evaluate retinal and optic nerve head (ONH) perfusion in patients with atrial fibrillation (AF) before and after catheter ablation of AF with pulmonary vein isolation (PVI). METHODS: 34 eyes of 34 patients with AF and 35 eyes of 35 healthy subjects were included in this study. Flow density data were obtained using spectral-domain OCT-A (RTVue XR Avanti with AngioVue, Optovue, Inc, Fremont, California, USA). The data of the superficial and deep vascular layers of the macula and the ONH (radial peripapillary capillary network, RPC) before and after PVI were extracted and analysed. RESULTS: The flow density in the superficial OCT-angiogram (whole en face) and the ONH (RPC) in patients with AF was significantly lower compared to healthy controls (OCT-A superficial: study group: 48.77 (45.19; 52.12)%; control group: 53.01 (50.00; 54.25)%; p < 0.001; ONH: study group: 51.82 (48.41; 54.03)%; control group: 56.00 (54.35; 57.70)%; p < 0.001;). The flow density in the ONH (RPC) improved significantly in the study group following PVI (before: 51.82 (48.41; 54.03)%; after: 52.49 (50.34; 55.62)%; p = 0.007). CONCLUSIONS: Patients with AF showed altered ocular perfusion as measured using OCTA when compared with healthy controls. Rhythm control using PVI significantly improved ocular perfusion as measured using OCT-A. Non-contact imaging using OCTA provides novel information about the central global microperfusion of patients with AF.
