In contrast, for patients with an existing diagnosis of HF at trial enrollment, we believe added prospective data collection at baseline is imperative to best explore the impact of therapy in various HF subsets based on EF, baseline HF therapy, and severity of disease. fraction, or HF therapy at time of incident HF diagnosis. HF hospitalization data were available in 15 trials, but only 2 included a HF-related event within the primary composite endpoint. This systematic review highlights gaps in HF data capture within cardiovascular outcome trials of glucose lowering therapies and outlines rationale and strategies for improving HF characterization. Reporting of HF KR2_VZVD antibody prevalence, definition for pre-existing HF, ejection fraction (EF), New York Heart Association (NYHA) class (data provided for patients or referenced in study selection criteria), NP level, and baseline HF therapy (including diuretic therapy). Ascertainment of new-onset HF, definition for new-onset HF, adjudication of new-onset HF, reporting of information at the time of new HF diagnosis (care setting of diagnosis, EF, NP level, HF therapies received), and clinical event reporting subsequent to new HF diagnosis. Reporting of fatal HF events, HF hospitalizations, emergency department visits for HF, outpatient worsening HF, inclusion of a HF event within Nisoxetine hydrochloride the primary composite trial outcome, and adjudication of reported HF events. Data Analysis As appropriate, descriptive analyses were performed, ranges were presented, and proportions were assessed. In circumstances where rates of baseline or incident HF for the overall study population were not provided, these rates were manually calculated from the raw trial data, when available. Analyses were performed using STATA version 14.0 (Stata Corporation, College Station, TX). RESULTS Studies The initial query yielded a total of 8,447 potentially relevant abstracts, of which 4,478 remained after removing duplicates. Based on manual screen of each of the remaining articles, 4,457 articles did not meet the systematic review eligibility criteria and were excluded. The remaining 21 articles were included in the systematic review which included a total of 152,737 patients. Figure 1 shows a PRISMA flow chart outlining the search strategy. SGLT-2 inhibitors and DPP- 4 inhibitors were studied by 3 trials each, while peroxisome proliferator-activated receptor modulators and GLP-1 receptor agonists were studied by 4 trials each. Remaining trials evaluated other drug therapies (including insulin regimens) or the role of intensive glycemic control. Baseline Heart Failure Of the 21 trials, prevalence of baseline HF was reported in 14 (67%) studies (Table 1). One study, the ORIGIN (Outcome Reduction with an Initial Glargine Intervention) trial, listed HF as an exclusion criterion. LEADER (Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results) and SUSTAIN-6 (Trial to Evaluate Cardiovascular and Other Long-term Outcomes with Semaglutide in Subjects with Type 2 Diabetes) included NYHA class IICIII HF as trial eligibility criteria in patients above the age of 50 years.(21,22) Excluding ORIGIN, all trials not providing baseline HF prevalence were published prior to 2010. Among studies reporting baseline HF, prevalence ranged from 0.5% in the RECORD (Rosiglitazone Evaluated for Cardiovascular Outcomes in Oral Combination Therapy for Type 2 Diabetes) trial to 27.9% in the EXAMINE (Examination of Cardiovascular Outcomes with Alogliptin versus Standard of Care) trial (15,23). Table 1 Reporting of baseline heart failure among cardiovascular outcomes trials of glucose lowering medications HF at baseline, and b) evaluation of safety and/or efficacy signals among those prevalent HF at baseline. As such, subgroup analysis by presence or absence of baseline HF should be standard and adequate enrollment of both subgroups should be ensured to allow for meaningful analysis. Although dedicated trials of glucose lowering therapies among patients with established HF will likely remain necessary for purposes of drug labeling and changing HF guidelines, we believe that accurately defining and characterizing HF within CV outcome trials is critical Nisoxetine hydrochloride for successful application of safety and efficacy findings to routine clinical practice. Moreover, and perhaps underappreciated, we believe that CV outcome trials may have the important potential to inform HF prevention strategies and potentially change prevention guidelines (although dedicated trials would likely be required for class I recommendations). Acknowledgement of these 2 discrete objectives sets a framework for specific strategies aimed at improving HF characterization in future CV outcome trials of glucose lowering therapies. To define the CV profile of these brokers more comprehensively, we propose a modified approach in emerging CV outcome trials of glucose lowering therapies focused on the following elements: Population Enrolled: CV outcome trials should routinely enroll sufficient number of patients with baseline HF to.Although differences in local laboratory assays could impede interpretation of NP data collected at the time of HF events, data reflecting levels in relation to local upper reference limits could be considered. incident HF diagnosis.
