Blood pressure and cardiovascular effects of new and emerging antidiabetic agents.

ABSTRACT: Despite remarkable declines in US cardiovascular disease morbidity and mortality over the last several decades, the prevalence of risk factors such as type 2 diabetes and hypertension remains high, associated with increasing obesity rates. Although optimal glycemic control remains a primary focus to decrease the disease burden, the FDA has issued guidance recommendations for documenting cardiovascular disease-related safety with research trials on new antidiabetic agents with more demanding requirements compared to past approval of existing therapies. This review will discuss the public health impact of type 2 diabetes, specifically with comorbid hypertension; mechanisms of action of the newest antidiabetic drug classes; and preliminary findings and potential clinical significance of the favorable blood pressure and body weight effects of the sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide 1 receptor agonists; and additionally discuss two recent large cardiovascular outcome trials with dipeptidyl peptidase-4 inhibitors.

Project description:IntroductionCardiovascular benefits observed with new antidiabetic agents may not extend to chronic kidney disease (CKD) patients. This study performed a systematic review and meta-analysis of cardiovascular outcome trials (CVOTs) using new antidiabetic agents stratified by kidney function.MethodsMEDLINE (via PubMed) and the Cochrane Central Register of Controlled Trials were searched for eligible studies up to November 16, 2020. Data were stratified by the trial entry estimated glomerular filtration rate (eGFR) and albuminuria. Primary major cardiovascular event (MACE) outcomes were extracted, and a meta-analysis with a random effects model was performed to estimate overall risk ratios (RRs).ResultsOur search identified 16 studies for inclusion (glucagon-like peptide-1 [GLP-1] analogues, n = 6; dipeptidyl-peptidase 4 [DPP-4] inhibitors, n = 4; and sodium-glucose cotransporter-2 [SGLT-2] inhibitors, n = 6) with a combined total of 150,816 participants (28.2% with eGFR <60 ml/min per 1.73 m2, n = 42,534). The RR for MACE with GLP-1 analogues with an eGFR ≥60 ml/min per 1.73 m2 was 0.87 (95% confidence interval [CI], 0.77-0.98; P = 0.02) and 0.90 (95% CI, 0.78-1.04; P = 0.14) with an eGFR <60 ml/min per 1.73 m2. The RR for MACE with DPP-4 inhibitors with eGFR ≥60 ml/min per 1.73 m2 was 0.99 (95% CI, 0.92-1.07; P = 0.86) and 0.99 (95% CI, 0.91-1.08; P = 0.86) with an eGFR <60 ml/min per 1.73 m2. The RR for MACE with SGLT-2 inhibitors with an eGFR ≥60 ml/min per 1.73 m2 was 1.01 (95% CI, 0.92-1.10; P = 0.87) and 0.85 (95% CI, 0.75-0.95; P = 0.005) with an eGFR <60 ml/min per 1.73 m2. Most analyses had significant heterogeneity. Sufficient albuminuria data were unavailable to analyze empirically.ConclusionClear evidence for MACE prevention in diabetes patients with an eGFR <60 ml/min per 1.73 m2 currently exists for SGLT-2 inhibitors only. However, similar GLP-1 analogue effect sizes suggest a lack of sufficient power rather than a lack of effect.

Project description:BackgroundThe risk for cardiovascular events increases within hours of near-roadway exposures. We aimed to determine the traffic-related air pollution (TRAP) and biological mechanisms involved and if reducing particulate matter <2.5 µm (PM2.5) inhalation is protective.MethodsFifty healthy-adults underwent multiple 2-hour near-roadway exposures (Tuesdays to Fridays) in Ann Arbor during 2 separate weeks (randomized to wear an N95 respirator during 1 week). Monday both weeks, participants rested 2 hours in an exam room (once wearing an N95 respirator). Brachial blood pressure, aortic hemodynamics, and heart rate variability were repeatedly measured during exposures. Endothelial function (reactive hyperemia index [RHI]) was measured post-exposures (Thursdays). Black carbon (BC), total particle count (PC), PM2.5, noise and temperature were measured throughout exposures.ResultsPM2.5 (9.3 ± 7.7 µg/m3), BC (1.3 ± 0.6 µg/m3), PC (8,375 ± 4,930 particles/cm3) and noise (69.2 ± 4.2 dB) were higher (P values <0.01) and aortic hemodynamic parameters trended worse while near-roadway (P values<0.15 vs. exam room). Other outcomes were unchanged. Aortic hemodynamics trended towards improvements with N95 respirator usage while near-roadway (P values<0.15 vs. no-use), whereas other outcomes remained unaffected. Higher near-roadway PC and BC exposures were associated with increases in aortic augmentation pressures (P values<0.05) and trends toward lower RHI (P values <0.2). N95 respirator usage did not mitigate these adverse responses (nonsignificant pollutant-respirator interactions). Near-roadway outdoor-temperature and noise were also associated with cardiovascular changes.ConclusionsExposure to real-world combustion-derived particulates in TRAP, even at relatively low concentrations, acutely worsened aortic hemodynamics. Our mixed findings regarding the health benefits of wearing N95 respirators support that further studies are needed to validate if they adequately protect against TRAP given their growing worldwide usage.
