Duration and kind of dual antiplatelet therapy for acute coronary syndrome patients: a network meta-analysis.

INTRODUCTION: For acute coronary syndrome (ACS) patients treated with percutaneous coronary intervention (PCI), the choice of the duration and kind of dual antiplatelet therapy (DAPT) offering the most accurate balance between ischemic and bleeding risk remains unknown. EVIDENCE ACQUISITION: A network meta-analysis was performed including all Randomized Controlled Trials (RCTs) comparing different DAPT regimens and duration in ACS patients undergoing PCI. Trial-defined MACE and major bleedings were the primary endpoints. Stroke, stent thrombosis (ST), all-cause and cardiovascular death, myocardial infarction (MI) represented secondary endpoints. EVIDENCE SYNTHESIS: 13 RCTs encompassing 46145 patients were included. Mean age was 62 (61-64) years old, 42% being admitted with STEMI, 33% with NSTEMI and 25% with UA. The competitive arms were: clopidogrel and aspirin for 12 months (6 arms/18183 patients), clopidogrel and aspirin for 6 months (4/3329), clopidogrel and aspirin >12 months (3/2238), ticagrelor and aspirin for 12 months (6/12942) and prasugrel and aspirin for 12 months (3/9453). Trial-defined MACE and major bleedings, stroke and death were similar among the different arms. DAPT with prasugrel and aspirin for 12 months reduced MI compared to aspirin and clopidogrel for 12 months (OR 0.71, 95% CI: 0.54.0.94) and reduced the risk of ST compared to ticagrelor (OR 0.66, 95% CI: 0.49-0.90). Both prasugrel and ticagrelor reduced ST as compared to clopidogrel and aspirin for 12 months. CONCLUSIONS: Different DAPT strategies yield similar risk of MACE, major bleeding, death and stroke in ACS patients. Prasugrel and aspirin for 12 months proved to be the most effective strategy regarding ST and MI.

Comparing benefits from sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists in randomized clinical trials: a network meta-analysis.

INTRODUCTION: Glucagon-like peptide 1 receptor agonists (GLP1-RA) and sodium-glucose cotransporter-2 inhibitors (SGLT2i) were individually proven to reduce major adverse cardiovascular events (MACE) in type 2 diabetes mellitus (T2DM) patients, but the relative magnitude of benefits from these two drug classes is debated. We aimed to review current available data on GLP1-RA and SGLT2i in T2DM patients and compare their efficacy and safety in this population. EVIDENCE ACQUISITION: We systematically searched MEDLINE/PubMed, the Cochrane Library, Google Scholar, Embase, www.tctmd.com, www.clinicaltrials.gov, www.clinicaltrialresults.org, from inception to September 17, 2020 for randomized controlled trials (RCTs) comparing the effects of GLP1-RA vs. SGLT2i vs. optimal medical therapy (OMT) in adult T2DM patients. Three authors independently screened references and extracted data using a predefined data collection form. Outcomes were analyzed using an indirect comparison meta-analysis of aggregate study-level data. The primary combined efficacy outcome comprised cardiovascular death, nonfatal myocardial infarction (MI), or nonfatal stroke. Secondary efficacy outcomes included all-cause mortality, cardiovascular mortality, non-fatal MI, non-fatal stroke, heart failure hospitalizations (HFH), and worsening renal function (WRF). EVIDENCE SYNTHESIS: Eleven RCTs enrolling a total of 98572 patients were included; 56004 (57%) patients were derived from GLP1-RA RCTs and 42568 (43%) from SGLT2i RCTs. At a median follow-up of 3.0±1.3 years, compared with OMT, both GLP1-RA and SGLT2i similarly reduced the rate of the composite primary outcome (risk ratio [RR] 0.88; 95% confidence interval [95% CI] 0.83-0.93 and RR 0.88, 95% CI: 0.82-0.95, respectively) with no difference between the drug classes (RR 1.00, 95% CI: 0.92-1.10). Both classes similarly reduced MI rate, cardiovascular and all-cause mortality compared with OMT; stroke reduction was only observed with GLP1-RA with no difference in the indirect comparison with SGLT2i; conversely, only SGLT2i were effective in preventing HFH. Both GLP1-RA and SGLT2i were protective against WRF, with a major efficacy of SGLT2i in the indirect comparison. CONCLUSIONS: This meta-analysis report that GLP1-RA and SGLT2i reduced with a similar efficacy not only MACE as MI, but also cardiovascular mortality and all-cause mortality at a median 3-year follow-up. SGLT2i were more protective in HFH and WRF than GLP1RA. These new data highlight the efficacy of SGLT2i not only in HF and chronic kidney disease (CKD) but also in ischemic heart diseases (IHD), with a homogeneity among the class, whereas the results observed with GLP1-RA are heterogenous. These findings will help clinical's decisions to optimize therapeutic strategies for diabetic patients.

In-hospital outcomes in nonagenarian patients undergoing primary percutaneous coronary intervention.

BACKGROUND: The aim of the present analysis was to evaluate the incidence and predictors of in-hospital adverse outcomes in nonagenarian patients undergoing primary percutaneous coronary intervention (pPCI) for ST-segment elevation myocardial infarction (STEMI). METHODS: Consecutive nonagenarian patients undergoing pPCI for STEMI from 2009 to 2019 were retrospectively included in an international multicenter registry. In-hospital all-cause death was the primary outcome. RESULTS: A total of 308 patients were included (mean age 92.5±2.5 years, 65.6% female). Mean systolic blood pressure (SBP) at hospital admission was 130.7±33.5 mmHg, 46 (17%) patients presented with a Killip class III-IV, mean left ventricle ejection fraction (LVEF) was 40.0±11.5% and 147 (58%) patients were independent in everyday activities. In-hospital death occurred in 99 patients (32%). After multivariate adjustment, lower LVEF (OR per unit reduction 1.08, 95% CI: 1.03-1.11, P value <0.001), lower SBP (OR 1.02 per mmHg reduction, 95% CI: 1.01-1.03, P value 0.001) and being not independent at home (OR 2.56, 95% CI: 1.25-5.26, P value 0.01) resulted independent predictors of in-hospital mortality. A sensitivity analysis performed in final TIMI 3 flow population confirmed the prognostic role of LVEF and independency on in-hospital mortality. CONCLUSIONS: Nonagenarian patients presenting with STEMI and undergoing pPCI have high in-hospital mortality. Independency in everyday life is a strong independent predictor of survival to hospital discharge.

How to fill the GAPS-I in secondary prevention: application of a strategy based on GLP1 analogues, antithrombotic agents, PCSK9 inhibitors, SGLT2 inhibitors and immunomodulators.

The continuous progress in cardiovascular risk prevention strategies has led to an impressive reduction in mortality and recurrent ischemic events in patients with coronary artery disease (CAD). However, the control of several cardiovascular risk factors remains suboptimal in many CAD patients, with a high rate of recurrent events, underlying the need for more new prevention strategies. The GAPS-I (glucagon-like peptide 1 analogues, antithrombotic agents, proprotein convertase subtilisin/kexin type 9 inhibitors, sodium glucose cotransporter type 2 inhibitors and immunomodulators) strategy offers a promising potential in patients with a high-residual cardiovascular risk, who are frequently encountered in daily practice, by offering an individualized and structured approach to addressing their individual risk factors. The current review summarizes the evidence to date on each of its components, with respect to clinical outcomes and economic feasibility. The current evidence points to an efficacy of GAPS-I in reducing major adverse cardiovascular events and mortality, without a compromise on safety, albeit with the need for longer follow-up data.

Echocardiographic estimation of right ventricular wall tension: haemodynamic comparison and long-term follow-up.

Prognosis in pulmonary hypertension is strictly linked to right ventricle failure, which results from uncoupling between right ventricle function and its afterload. This study sought to describe how to estimate with echocardiography right ventricular wall tension, its correlation with right ventricle haemodynamics and its prognostic role. A total of 190 patients without overt right ventricle failure but with suspected pulmonary hypertension on a previous echocardiogram underwent right heart catheterization and nearly-simultaneous echocardiography. Right ventricular wall tension was estimated according to Laplace's law as right ventricle length × tricuspid regurgitation peak gradient and it was correlated with right ventricle haemodynamic profile; its potential prognostic impact was tested along with canonical right ventricle function parameters. Right ventricular wall tension correlated significantly with invasive estimation of right ventricle end-diastolic pressure (R: 0.343, p < 0.001) and with several other haemodynamic variables, such as mean pulmonary artery pressure, pulmonary artery compliance, transpulmonary gradient, pulmonary vascular resistance, right atrial pressure and right ventricle stroke work index (all p < 0.001). At a mean follow-up of five years and three months, only right ventricular wall tension was associated to all-cause mortality (p = 0.036), while tricuspid annular plane systolic excursion (p = 0.536), right ventricle fractional area change (p = 0.383), right ventricle fractional area change (p = 0.076), tricuspid regurgitation peak gradient (p = 0.107) and tricuspid annular plane systolic excursion/tricuspid regurgitation peak gradient (p = 0.181) could not. We identified a novel bedside echocardiographic predictor of altered right ventricle haemodynamics, which is precociously altered in patients without overt right ventricle failure and is associated to all-cause mortality at a long-term follow-up. Further studies are needed to confirm its role in pulmonary hypertension patients.
