AimsThe objective of the present study is to assess the prognostic value of acute kidney injury (AKI) in the evolution of patients with heart failure (HF) using real-world data. Methods and results Patients with a diagnosis of HF and with serial measurements of renal function collected throughout the study period were included. Estimated glomerular filtration rate (GFR) was calculated with the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration). AKI was defined when a sudden drop in creatinine with posterior recovery was recorded. According to the Risk, Injury, Failure, Loss, and End-Stage Renal Disease (RIFLE) scale, AKI severity was graded in three categories: risk [1.5-fold increase in serum creatinine (sCr)], injury (2.0-fold increase in sCr), and failure (3.0-fold increase in sCr or sCr > 4.0 mg/dL). AKI incidence and risk of hospitalization and mortality after the first episode were calculated by adjusting for potential confounders. A total of 30 529 patients with HF were included. During an average follow-up of 3.2 years, 5294 AKI episodes in 3970 patients (13.0%) and incidence of 3.3/100 HF patients/year were recorded. One episode was observed in 3161 (10.4%), two in 537 (1.8%), and three or more in 272 (0.9%). They were more frequent in women with diabetes and hypertension. The incidence increases across the GFR levels (Stages 1 to 4: risk 7.6%, 6.8%, 11.3%, and 12.5%; injury 2.1%, 2.0%, 3.3%, and 5.5%; and failure 0.9%, 0.6%. 1.4%, and 8.0%). A total of 3817 patients with acute HF admission were recorded during the follow-up, with incidence of 38.4/100 HF patients/year, 3101 (81.2%) patients without AKI, 545 (14.3%) patients with one episode, and 171 (4.5%) patients with two or more. The number of AKI episodes [one hazard ratio (HR) 1.05 (0.98-1.13); two or more HR 2.01 (1.79-2.25)] and severity [risk HR 1.05 (0.97-1.04); injury HR 1.41 (1.24-1.60); and failure HR 1.90 (1.64-2.20)] increases the risk of hospitalization. A total of 10 560 deaths were recorded, with incidence of 9.3/100 HF patients/year, 8951 (33.7%) of subjects without AKI episodes, 1180 (11.17%) of subjects with one episode, and 429 (4.06%) with two or more episodes. The number of episodes [one HR 1.05 (0.98-1.13); two or more HR 2.01 (1.79-2.25)] and severity [risk 1.05 confidence interval (CI) (0.97-1.14), injury 1.41 (CI 1.24-1.60), and failure 1.90 (CI 1.64-2.20)] increases mortality risk. Conclusions The study demonstrated the worse prognostic value of sudden renal function decline in HF patients and pointed to those with more future risk who require review of treatment and closer follow-up.

The specific management of infective endocarditis (IE) in elderly patients is not specifically addressed in recent guidelines despite its increasing incidence and high mortality in this population. The term “elderly” corresponds to different ages in the literature, but it is defined by considerable comorbidity and heterogeneity. Cancer incidence, specifically colorectal cancer, is increased in older patients with IE and impacts its outcome. Diagnosis of IE in elderly patients is challenging due to the atypical presentation of the disease and the lower performance of imaging studies. Enterococcal etiology is more frequent than in younger patients. Antibiotic treatment should prioritize diminishing adverse effects and drug interactions while maintaining the best efficacy, as surgical treatment is less commonly performed in this population due to the high surgical risk. The global assessment of elderly patients with IE, with particular attention to frailty and geriatric profiles, should be performed by multidisciplinary teams to improve disease management in this population.

AimsTo assess the impact of anticoagulant treatment on risk for stroke and all-cause mortality of patients with atrial fibrillation using real-world data (RWD).MethodsPatients with prevalent or incident atrial fibrillation were selected throughout a study period of 5 years. Stroke, transitory ischemic attack, hemorrhagic stroke, and all-cause mortality were identified in the claims of the electronic health records (EHRs). Subjects were classified according to the anticoagulant treatment in four groups: untreated, vitamin K antagonists (VKAs), New Oral Anticoagulants (NOACs), and antiplatelet (AP). Risk of events and protection with anticoagulant therapy were calculated by Cox proportional hazard models adjusted by potential confounders.ResultsFrom a total population of 3,799,884 patients older than 18,123,227 patients with incident or prevalent atrial fibrillation (AF) were identified (mean age 75.2 ± 11.5 years old; 51.9% women). In a follow-up average of 3.2 years, 17,113 patients suffered from an ischemic stroke and transitory ischemic attack (TIA), 780 hemorrhagic stroke, and 42,558 all-cause death (incidence of 46, 8, 2, and 120 per 1,000 patients/year, respectively). Among CHA2DS2, VASc Score equal or >2, 11.7% of patients did not receive any anticoagulant therapy, and a large proportion of patients, 47%, shifted from one treatment to another. Although all kinds of anticoagulant treatments were significantly protective against the events and mortality, NOAC treatment offered significantly better protection compared to the other groups.ConclusionIn the real world, the use of anticoagulant treatments is far from guidelines recommendations and is characterized by variability in their use. NOACs offered better protection compared with VKAs.

Objective: To assess the impact of hypertension in the risk of cardiovascular events and mortality in a population of diabetic patients from a Mediterranean population based in Real World Evidence. Design and method: The sample was recruited from beneficiaries of the Valencian Health Agency's health care system, with a population of 3799884 people older than 25 years in 2012. The observational study was undertaken as part of routine clinical practice from January 2012 to December 2016. Diabetes was defined as a non-fasting glucose higher or equal to 200 mg/dl, a recorded physician diagnosis, medication use or an HbA1c higher or equal to 6.5%. Hypertension was defined by a recorded physician diagnosis or antihypertensive medication use. Estimated glomerular filtration rate (eGFR) was calculated from calibrated creatinine, age and sex using the CKD-EPI and CKD was defined when eGFR < 60 ml/min/1.73m2. Vital status was determined by matching records and death certificates from the Spanish National Death Index. Results: Among the total population of 3799884, DM was present in 510922 (13%) patients (12% in women and 15% in men), Average of HbA1c was 6.9% + 1.4%. Hypertension was recorded in 387590 (75%) with a rate of BP < 140/90 mmHg of 45% and CKD in 125441 (24%). The incidence rates for DM, with and without diagnostic of HTN, of acute myocardial infarction, heart failure and stroke, as well all-cause mortality by age and sex rates are in the figure, in which the times of increment of risk due to the presence of HTN is presented. Conclusions: Presence of HTN in patients of diabetes largely increases the risk of MI, stroke, HF and all-cause mortality. The impact even it is higher in more younger patients, it still until the last decade of life.
