Single versus dual antiplatelet therapy following percutaneous left atrial appendage closure-A systematic review and meta-analysis.

BACKGROUND: In the last few years, percutaneous LAA occlusion (LAAO) has become a plausible alternative in atrial fibrillation (AF) patients with contraindications to anticoagulation therapy. Nevertheless, the optimal antiplatelet strategy following percutaneous LAAO remains to be defined. METHODS: Studies comparing single antiplatelet therapy (SAPT) versus dual antiplatelet therapy (DAPT) following LAAO were systematically searched and screened. The outcomes of interest were ischemic stroke, device-related thrombus (DRT) and major bleeding. A random-effect meta-analysis was performed comparing outcomes in both groups. The moderator effect of baseline characteristics on outcomes was evaluated by univariate meta-regression analyses. RESULTS: Sixteen observational studies with 3255 patients treated with antiplatelet therapy (SAPT, n = 1033; DAPT, n = 2222) after LAAO were included. Mean age was 74.5 ± 8.3 years, mean CHA2DS2-VASc and HAS-BLED scores were 4.3 ± 1.5 and 3.2 ± 1.0, respectively. At a weighted mean follow-up of 12.7 months, the occurrence of stroke (RR 1.33; 95% CI 0.64-2.77; p =.44), DRT (RR 1.52; 95% CI 0.90-2.58; p =.12), and the composite of stroke and DRT (RR 1.26; 95% CI 0.67-2.37; p =.47) did not differ significantly between SAPT and DAPT groups. The rate of major bleedings was also not different between groups (RR 1.41; 95% CI 0.64-3.12; p =.39). CONCLUSIONS: Among AF patients at high bleeding risk undergoing percutaneous LAAO, a post-procedural minimalistic antiplatelet strategy with SAPT did not significantly differ from DAPT regimens regarding the rate of stroke, DRT and major bleeding.

Continuous stellate ganglion block for ventricular arrhythmias: case series, systematic review, and differences from thoracic epidural anaesthesia.

AIMS: Percutaneous stellate ganglion block (PSGB) through single-bolus injection and thoracic epidural anaesthesia (TEA) have been proposed for the acute management of refractory ventricular arrhythmias (VAs). However, data on continuous PSGB (C-PSGB) are scant. The aim of this study is to report our dual-centre experience with C-PSGB and to perform a systematic review on C-PSGB and TEA. METHODS AND RESULTS: Consecutive patients receiving C-PSGB at two centres were enrolled. The systematic literature review follows the latest Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Our case series (26 patients, 88% male, 60 ± 16 years, all with advanced structural heart disease, left ventricular ejection fraction 23 ± 11%, 32 C-PSGBs performed, with a median duration of 3 days) shows that C-PSGB is feasible and safe and leads to complete VAs suppression in 59% and to overall clinical benefit in 94% of cases. Overall, 61 patients received 68 C-PSGBs and 22 TEA, with complete VA suppression in 63% of C-PSGBs (61% of patients). Most TEA procedures (55%) were performed on intubated patients, as opposed to 28% of C-PSGBs (P = 0.02); 63% of cases were on full anticoagulation at C-PSGB, none at TEA (P < 0.001). Ropivacaine and lidocaine were the most used drugs for C-PSGB, and the available data support a starting dose of 12 and 100 mg/h, respectively. No major complications occurred, yet TEA discontinuation rate due to side effects was higher than C-PSGB (18 vs. 1%, P = 0.01). CONCLUSION: Continuous PSGB seems feasible, safe, and effective for the acute management of refractory VAs. The antiarrhythmic effect may be accomplished with less concerns for concomitant anticoagulation compared with TEA and with a lower side-effect related discontinuation rate.

Impact of statin adherence and interruption within 6 months after ST-segment elevation myocardial infarction (STEMI): Results from the real-world regional registry FAST-STEMI.

BACKGROUND: The impact of statin therapy on cardiovascular outcomes after ST-elevation acute myocardial infarction (STEMI) in real- world patients is understudied. AIMS: To identify predictors of low adherence and discontinuation to statin therapy within 6 months after STEMI and to estimate their impact on cardiovascular outcomes at one year follow-up. METHODS: We evaluated real-world adherence to statin therapy by comparing the number of bought tablets to the expected ones at 1 year follow-up through pharmacy registries. A total of 6043 STEMI patients admitted from 2012 to 2017 were enrolled in the FAST STEMI registry and followed up for 4,7 ± 1,6 years; 304 patients with intraprocedural and intrahospital deaths were excluded. The main outcomes evaluated were all-cause death, cardiovascular death, myocardial infarction, major and minor bleeding events, and ischemic stroke. The compliance cut-off chosen was 80% as mainly reported in literature. RESULTS: From a total of 5744 patients, 418 (7,2%) patients interrupted statin therapy within 6 months after STEMI, whereas 3337 (58,1%) presented >80% adherence to statin therapy. Statin optimal adherence (>80%) resulted as protective factor towards both cardiovascular (0.1% vs 4.6%; AdjHR 0.025, 95%CI 0.008-0.079, p < 0.001) and all-cause mortality (0.3% vs 13.4%; Adj HR 0.032, 95%CI 0.018-0.059, p < 0.001) at 1 year follow-up. Further, a significant reduction of ischemic stroke incidence (1% vs 2.5%, p = 0.001) was seen in the optimal adherent group. Statin discontinuation within 6 months after STEMI showed an increase of both cardiovascular (5% vs 1.7%; AdjHR 2.23; 95%CI 1.37-3.65; p = 0,001) and all-cause mortality (14.8% vs 5.1%, AdjHR 2.32; 95%CI 1.73-3.11; p ã€ˆ0,001) at 1 year follow-up. After multivariate analysis age over 75 years old, known ischemic cardiopathy and female gender resulted as predictors of therapy discontinuation. Age over 75 years old, chronic kidney disease, previous atrial fibrillation, vasculopathy, known ischemic cardiopathy were found to be predictors of low statin adherence. CONCLUSIONS: n our real-world registry low statin adherence and discontinuation therapy within 6 months after STEMI were independently associated to an increase of cardiovascular and all-cause mortality at 1 year follow-up. Low statin adherence led to higher rates of ischemic stroke.

The Intrinsic Cardiac Nervous System: From Pathophysiology to Therapeutic Implications.

The cardiac autonomic nervous system (CANS) plays a pivotal role in cardiac homeostasis as well as in cardiac pathology. The first level of cardiac autonomic control, the intrinsic cardiac nervous system (ICNS), is located within the epicardial fat pads and is physically organized in ganglionated plexi (GPs). The ICNS system does not only contain parasympathetic cardiac efferent neurons, as long believed, but also afferent neurons and local circuit neurons. Thanks to its high degree of connectivity, combined with neuronal plasticity and memory capacity, the ICNS allows for a beat-to-beat control of all cardiac functions and responses as well as integration with extracardiac and higher centers for longer-term cardiovascular reflexes. The present review provides a detailed overview of the current knowledge of the bidirectional connection between the ICNS and the most studied cardiac pathologies/conditions (myocardial infarction, heart failure, arrhythmias and heart transplant) and the potential therapeutic implications. Indeed, GP modulation with efferent activity inhibition, differently achieved, has been studied for atrial fibrillation and functional bradyarrhythmias, while GP modulation with efferent activity stimulation has been evaluated for myocardial infarction, heart failure and ventricular arrhythmias. Electrical therapy has the unique potential to allow for both kinds of ICNS modulation while preserving the anatomical integrity of the system.

De-escalation of dual antiplatelet therapy for patients with acute coronary syndrome after percutaneous coronary intervention: a systematic review and network meta-analysis.

OBJECTIVES: To compare dual antiplatelet therapy (DAPT) de-escalation with five alternative DAPT strategies in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). DESIGN: We conducted a systematic review and network meta-analysis (NMA). Parallel-arm randomised controlled trials (RCTs) comparing DAPT strategies were included and arms of interest were compared via NMA. Partial ranking of each identified arm and for each investigated endpoint was also performed. SETTING AND PARTICIPANTS: Adult patients with ACS (≥18 years) undergoing PCI with indications for DAPT. SEARCH METHODS: A comprehensive search covered several databases (PubMed, Embase, Cochrane Central, MEDLINE, Conference Proceeding Citation Index-Science) from inception to 15 October 2023. Medical subject headings and keywords related to ACS, PCI and DAPT interventions were used. Reference lists of included studies were screened. Clinical trials registers were searched for ongoing or unpublished trials. INTERVENTIONS: Six strategies were assessed: T1 arm: acetylsalicylic acid (ASA) and prasugrel for 12 months; T2 arm: ASA and low-dose prasugrel for 12 months; T3 arm: ASA and ticagrelor for 12 months; T4 arm: DAPT de-escalation (ASA+P2Y12 inhibitor for 1-3 months, then single antiplatelet therapy with potent P2Y12 inhibitor or DAPT with clopidogrel); T5 arm: ASA and clopidogrel for 12 months; T6 arm: ASA and clopidogrel for 3-6 months. MAIN OUTCOME MEASURES: Primary outcome: Cardiovascular mortality. SECONDARY OUTCOMES: bleeding events (all, major, minor), stent thrombosis (ST), stroke, myocardial infarction (MI), all-cause mortality, major adverse cardiovascular events (MACE). RESULTS: 23 RCTs (75 064 patients with ACS) were included. No differences in cardiovascular mortality, all-cause death, recurrent MI or MACE were found when the six strategies were compared, although with different levels of certainty of evidence. ASA and clopidogrel for 12 or 3-6 months may result in a large increase of ST risk versus ASA plus full-dose prasugrel (OR 2.00, 95% CI 1.14 to 3.12, and OR 3.42, 95% CI 1.33 to 7.26, respectively; low certainty evidence for both comparisons). DAPT de-escalation probably results in a reduced risk of all bleedings compared with ASA plus full-dose 12-month prasugrel (OR 0.49, 95% CI 0.26 to 0.81, moderate-certainty evidence) and ASA plus 12-month ticagrelor (OR 0.52, 95% CI 0.33 to 0.75), while it may not increase the risk of ST. ASA plus 12-month clopidogrel may reduce all bleedings versus ASA plus full-dose 12-month prasugrel (OR 0.66, 95% CI 0.42 to 0.94, low certainty) and ASA plus 12-month ticagrelor (OR 0.70, 95% CI 0.52 to 0.89). CONCLUSIONS: DAPT de-escalation and ASA-clopidogrel regimens may reduce bleeding events compared with 12 months ASA and potent P2Y12 inhibitors. 3-6 months or 12-month aspirin-clopidogrel may increase ST risk compared with 12-month aspirin plus potent P2Y12 inhibitors, while DAPT de-escalation probably does not.

Organ perfusion pressure at admission and clinical outcomes in patients hospitalized for acute heart failure.

AIMS: Hypoperfusion portends adverse outcomes in acute heart failure (AHF). The gradient between end-organ inflow and outflow pressures may more closely reflect hypoperfusion than mean arterial pressure (MAP) alone. The aim of this study was to investigate organ perfusion pressure (OPP), calculated as MAP minus central venous pressure (CVP), as a prognostic marker in AHF. METHODS AND RESULTS: The Sodium NItroPrusside Treatment in Acute Heart Failure (SNIP)-AHF study was a multicentre retrospective cohort study of 200 consecutive patients hospitalized for AHF treated with sodium nitroprusside. Only patients with both MAP and invasive CVP data available from the SNIP-AHF cohort were included in this analysis. The primary endpoint was to assess OPP as a predictor of worsening heart failure (WHF), defined as the worsening of signs and symptoms of heart failure leading to intensification of therapy at 48 h. One hundred and forty-six patients fulfilling the inclusion criteria were included [mean age: 61.1 ± 13.5 years, 32 (21.9%) females; mean body mass index: 26.2 ± 11.7 kg/m2; mean left ventricular ejection fraction: 23.8%±11.4%, mean MAP: 80.2 ± 13.2 mmHg, and mean CVP: 14.0 ± 6.1 mmHg]. WHF occurred in 14 (9.6%) patients. At multivariable models including hemodynamic variables (OPP, shock index, and CVP), OPP at admission was the best predictor of WHF at 48 h [OR 0.91 (95% confidence interval 0.86-0.96), P-value = 0.001] with an optimal cut-off value of 67.5 mmHg (specificity 47.3%, sensitivity 100%, and AUC 0.784 ± 0.054). In multivariable models, including univariable significant parameters available at first bedside assessment, namely New York Heart Association functional class, OPP, shock index, CVP, and left ventricular end-diastolic diameter, OPP consistently and significantly predicted WHF at 48 h. CONCLUSION: In this retrospective analysis on patients hospitalized for AHF treated with sodium nitroprusside, on-admission OPP significantly predicted WHF at 48 h with high sensitivity.

Acute Reduction in Left Ventricular Function Following Transcatheter Mitral Edge-to-Edge Repair.

Background Little is known about the impact of transcatheter mitral valve edge-to-edge repair on changes in left ventricular ejection fraction (LVEF) and the effect of an acute reduction in LVEF on prognosis. We aimed to assess changes in LVEF after transcatheter mitral valve edge-to-edge repair for both primary and secondary mitral regurgitation (PMR and SMR, respectively), identify rates and predictors of LVEF reduction, and estimate its impact on prognosis. Methods and Results In this international multicenter registry, patients with both PMR and SMR undergoing transcatheter mitral valve edge-to-edge repair were included. We assessed rates of acute LVEF reduction (LVEFR), defined as an acute relative decrease of >15% in LVEF, its impact on all-cause mortality, major adverse cardiac event (composite end point of all-cause death, mitral valve surgery, and residual mitral regurgitation grade ≥2), and LVEF at 12 months, as well as predictors for LVEFR. Of 2534 patients included (727 with PMR, and 1807 with SMR), 469 (18.5%) developed LVEFR. Patients with PMR were older (79.0±9.2 versus 71.8±8.9 years; P<0.001) and had higher mean LVEF (54.8±14.0% versus 32.7±10.4%; P<0.001) at baseline. After 6 to 12 months (median, 9.9 months; interquartile range, 7.8-11.9 months), LVEF was significantly lower in patients with PMR (53.0% versus 56.0%; P<0.001) but not in patients with SMR. The 1-year mortality was higher in patients with PMR with LVEFR (16.9% versus 9.7%; P<0.001) but not in those with SMR (P=0.236). LVEF at baseline (odds ratio, 1.03 [95% CI, 1.01-1.05]; P=0.002) was predictive of LVEFR for patients with PMR, but not those with SMR (P=0.092). Conclusions Reduction in LVEF is not uncommon after transcatheter mitral valve edge-to-edge repair and is correlated with worsened prognosis in patients with PMR but not patients with SMR.

Sport activity in patients with cardiomyopathies: a review.

Exercise has undisputable benefits and is an important therapy component for most cardiovascular diseases, with a proven role in reducing mortality. On the contrary, exercise may paradoxically trigger sudden cardiac arrest in patients with cardiomyopathies requiring refrain from competitive sports participation. The 2020 European guidelines for patients with cardiovascular disease provided indication for sports participation for patients with cardiac conditions, including cardiomyopathies. Although in some cases, the knowledge of the natural history of the disease and the risk of death during intensive exercise is more robust, in others, the evidence is scarce. Therefore, recommendations are not available for all possible scenarios with several uncertainties. In addition, many patients aspire to continue competitive sports or practise recreational activities after a diagnosis of cardiomyopathy. These aspects generate concern for the physician, who should make complex decisions, and confronts the request to design specific exercise programmes without specific indications. This article will review the available evidence on the sports-related risk of sudden cardiac death or cardiovascular events and the progression of the disease in cardiomyopathies.

Electrical storm management in structural heart disease.

Electrical storm (ES) is a life-threatening condition characterized by at least three separate episodes of ventricular arrhythmias (VAs) over 24 h, each requiring therapeutic intervention, including implantable cardioverter defibrillator (ICD) therapies. Patients with ICDs in secondary prevention are at higher risk of ES and the most common presentation is that of scar-related monomorphic VAs. Electrical storm represents a major unfavourable prognostic marker in the history of patients with structural heart disease, with an associated two- to five-fold increase in mortality, heart transplant, and heart failure hospitalization. Early recognition and prompt treatment are crucial to improve the outcome. Yet, ES management is complex and requires a multidisciplinary approach and well-defined protocols and networks to guarantee a proper patient care. Acute phase stabilization should include a comprehensive clinical assessment, resuscitation and sedation management skills, ICD reprogramming, and acute sympathetic modulation, while the sub-acute/chronic phase requires a comprehensive heart team evaluation to define the better treatment option according to the haemodynamic and overall patient's condition and the type of VAs. Advanced anti-arrhythmic strategies, not mutually exclusive, include invasive ablation, cardiac sympathetic denervation, and, for very selected cases, stereotactic ablation. Each of these aspects, as well as the new European Society of Cardiology guidelines recommendations, will be discussed in the present review.

The Brugada syndrome: pharmacological therapy.

Brugada syndrome is an inherited channelopathy with an increased risk of sudden cardiac death (SCD) due to ventricular arrhythmias (VA) and an increased incidence of supraventricular arrhythmias, as compared with the general population. For the prevention of SCD, the guidelines recommend the implantable cardioverter-defibrillator (ICD); however, ICD does not prevent VA. In this article, we provide a brief review of the literature on the Brugada syndrome pharmacological therapy, mainly focusing on quinidine treatment. The efficacy of quinidine therapy in the prevention of VA in Brugada syndrome has been demonstrated by several small studies in patients with ICD and recurrent shocks or in asymptomatic patients with inducible ventricular fibrillation (VF) at electrophysiological study. Quinidine has also been tested for the prophylaxis of supraventricular arrhythmias, especially atrial fibrillation/flutter, and in paediatric patients. In these studies, quinidine proved highly effective in preventing re-induction of VF and spontaneous recurrences of both ventricular and supraventricular arrhythmias. Unfortunately, this therapy is burdened by a high incidence of side effects, which may lead to drug discontinuation.

Safety and feasibility of angiotensin receptor neprilysin inhibitor in real-world patients with acute decompensated heart failure.

BACKGROUND: The aim of this study was to determine the safety and feasibility of in-hospital sacubitril/valsartan initiation after clinical stabilization in patients with acute decompensated heart failure (ADHF) and reduced ejection fraction (EF). METHODS: This retrospective, multicenter observational study included patients admitted for ADHF in 2 Italian centers between February 2017 and January 2022. Feasibility was evaluated by assessing the proportion of patients discharged on sacubitril/valsartan. Key safety endpoints were the incidences of adverse events during hospitalization and during follow-up planned at 1 month, 3-6 months and 12-18 months after discharge. RESULTS: One hundred and twenty-two patients were included. Median age was 71 (60-78) years, 78% male, 63% New York Heart Association (NYHA) Class III at admission with a median left ventricular ejection fraction (EF) of 25% (20-30). During hospitalization, 94 (77%) patients were treated with intravenous diuretics, 39 (32%) with inotrope/vasopressor, 51 (42%) with continuous positive airway pressure ventilation and 7 (6%) were assisted with an intra-aortic balloon pump. Median time from hospitalization to sacubitril/valsartan initiation was 4 (2-7) days. Sacubitril/valsartan was started at a dosage of 12/13 mg in 52 (43%) patients, 24/26 mg in 61 (50%) patients and 49/51 mg in 8 (7%) patients. Overall, 111 (91%) patients were discharged on sacubitril/valsartan. At 12-18-month follow-up, the vast majority of patients were still on sacubitril/valsartan therapy. CONCLUSIONS: In-hospital initiation of sacubitril/valsartan treatment in real-world ADHF patients may be a safe and feasible treatment option.

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.

Prevalence and predictors of left atrial thrombosis in atrial fibrillation patients treated with non-vitamin K antagonist oral anticoagulants.

BACKGROUND: Few data are available regarding the prevalence of left atrium (LA) thrombi in atrial fibrillation (AF) patients treated with non-vitamin K antagonist oral anticoagulants (NOACs). Methods: We evaluated the prevalence and predictors of LA/LA appendage (LAA) thrombi in non-valvular AF patients treated with NOACs referring to a single centre for a scheduled electrical cardioversion (ECV) or catheter ablation (CA). Transesophageal echocardiography (TEE) was performed within 12 h prior to the index procedure. RESULTS: A total of 352 consecutive patients with non-valvular AF treated with NOACs were included in this analysis (ECV group n = 176 and CA group n = 176) between 2013 and 2018. 85 patients (24.2%) were on dabigatran, 150 (42.7%) on rivaroxaban, 104 (29.6%) on apixaban and 13 (3.7%) on edoxaban. A LA/LAA thrombus was detected by TEE in 27 (7.7%) patients, 18 in the ECV group and nine in the ablation group; 18 (5.1%) patients presented dense LA/LAA spontaneous echo contrast (SEC). Predictors of LA/LAA thrombi were a CHA2DS2-VASc score > 3 (OR 4.54, 95% CI 1.50 - 13.70, p value = .007) and obesity (OR 6.01, 95% CI 1.95 - 18.50, p value = .001). CONCLUSIONS: Among real-world patients with non-valvular AF treated with NOACs, we found a high incidence of LA/LAA thrombi compared to previous reports. The main predictors of LA/LAA thrombosis were a CHA2DS2-VASc score > 3 and obesity.

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.

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.

Outcomes of Transcatheter Edge-to-Edge Repair in Degenerative vs. Functional Mitral Regurgitation.

Current guidelines support the use of transcatheter edge-to-edge repair (TEER) for patients with both primary and secondary mitral regurgitation. We aimed to compare the prognoses of TEER in degenerative mitral regurgitation (DMR) vs. functional mitral regurgitation (FMR). A total of 208 consecutive patients who underwent TEER over a ten-year period were analyzed. Primary endpoints included rates of all-cause death and major adverse cardiac events (MACE: composite of all-cause death, hospitalizations for heart failure, mitral valve surgery, or TEER re-intervention). A total of 148 (71%) patients were identified with FMR, while 60 (29%) were identified with DMR. Patients in the FMR group were younger (77.2 ± 8.4 vs. 80.2 ± 7.2, p = 0.02), suffered more frequently from coronary artery disease (54.1% vs. 10.0%, p = 0.02), and atrial fibrillation/flutter (70.9% vs. 38.3%, p = 0.02). Rates of 1-year death (21.6% vs. 10.0%, p = 0.03) and MACE (41.2% vs. 21.7%, p = 0.02) were higher for the FMR group, as compared to the DMR group. After correcting for variables, FMR independently predicted rates of MACE (HR-1.78, 95% CI 1.23-2.48, p = 0.04) and had a non-significant effect on one-year mortality (HR-1.67, 95%CI 0.98-3.74, p = 0.07). In our experience, worse overall 1-year composite MACE outcomes were observed after TEER in patients with FMR as compared to patients with DMR.
