RESUMEN
Perioperative cardiovascular complications are important causes of morbidity and mortality associated with non-cardiac surgery, especially in patients with recent percutaneous coronary intervention (PCI). We aimed to illustrate the types and timing of different surgeries occurring after PCI, and to evaluate the risk of thrombotic and bleeding events according to the perioperative antiplatelet management. Patients undergoing urgent or elective non-cardiac surgery within 1 year of PCI at a tertiary-care center between 2011 and 2018 were included. The primary outcome was major adverse cardiac events (MACE; composite of death, myocardial infarction, or stent thrombosis) at 30 days. Perioperative bleeding was defined as ≥ 2 units of blood transfusion. A total of 1092 surgeries corresponding to 747 patients were classified by surgical risk (low: 50.9%, intermediate: 38.4%, high: 10.7%) and priority (elective: 88.5%, urgent/emergent: 11.5%). High-risk and urgent/emergent surgeries tended to occur earlier post-PCI compared to low-risk and elective ones, and were associated with an increased risk of both MACE and bleeding. Preoperative interruption of antiplatelet therapy (of any kind) occurred in 44.6% of all NCS and was more likely for procedures occurring later post-PCI and at intermediate risk. There was no significant association between interruption of antiplatelet therapy and adverse cardiac events. Among patients undergoing NCS within 1 year of PCI, perioperative ischemic and bleeding events primarily depend on the estimated surgical risk and urgency of the procedure, which are increased early after PCI. Preoperative antiplatelet interruption was not associated with an increased risk of cardiac events.

Since its introduction in 1977, percutaneous coronary intervention has become one of the most commonly performed therapeutic procedures worldwide. Such widespread diffusion, however, would have not been possible without a concomitant evolution of the pharmacotherapies associated with this intervention. Antithrombotic agents are fundamental throughout the management of patients undergoing coronary stent implantation, starting from the procedure itself to the long-term prevention of cardiovascular events. The last 40 years of interventional cardiology have seen remarkable improvements in both drug therapies and device technologies, which largely reflected a progressive understanding of the pathophysiological mechanisms of coronary artery disease, as well as procedure- and device-related adverse events. The purpose of this article is to provide an overview of the important milestones in antithrombotic pharmacology that have shaped clinical practice of today while also providing insights into knowledge gaps and future directions.

BACKGROUND: Long-term outcomes in patients at high bleeding risk (HBR) undergoing percutaneous coronary intervention with a drug-eluting stent are unclear. Therefore, we aimed to evaluate long-term adverse events in HBR patients undergoing percutaneous coronary intervention with cobalt-chromium everolimus-eluting stent implantation. METHODS: We analyzed stratified data from 4 all-comers postapproval registries. Patients with at least 1 of the following criteria were categorized as HBR: age ≥75 years, history of major bleeding (MB), history of stroke, chronic oral anticoagulant use, chronic kidney disease, anemia, or thrombocytopenia. Additionally, in a separate analysis, patients were categorized according to the recently published Academic Research Consortium HBR criteria. The Kaplan-Meier method was used for time-to-event analyses. Coronary thrombotic events (CTE) included myocardial infarction or definite/probable stent thrombosis. MB was defined according to the TIMI (Thrombolysis in Myocardial Infarction) or GUSTO (Global Use of Strategies to Open Occluded Coronary Arteries) scales. Impact of CTE and MB on subsequent risk of mortality was assessed using multivariable Cox regression with MB and CTE included as time-updated covariates. RESULTS: Of the total 10 502 patients included, 3507 (33%) were identified as HBR. Compared with non-HBR patients, those at HBR had more comorbidities, higher lesion complexity, and a higher risk of 4-year mortality (Hazard Ratio [HR] 4.38 [95% CI, 3.76-5.11]). Results were qualitatively similar when using Academic Research Consortium criteria to define HBR. Risk of mortality was increased after CTE (HR 5.02 [95% CI, 3.93-6.41]), as well as after MB (HR 4.92 [95% CI, 3.82-6.35]). Of note, this effect was consistent across the spectrum of bleeding risk (P-interaction test 0.97 and 0.06, respectively). CONCLUSIONS: Compared with the non-HBR population, HBR patients experienced worse 4-year outcomes after percutaneous coronary intervention with cobalt-chromium everolimus-eluting stent. Both CTE and MB had a significant impact on subsequent risk of mortality irrespective of bleeding risk.

BACKGROUND: Data examining the safety and efficacy of the bioabsorbable polymer (BP) drug-eluting stent (DES) as compared with durable polymer (DP) DES in high-risk patients undergoing percutaneous coronary intervention (PCI) remain limited. METHODS: We conducted a pre-specified analysis among patients enrolled in the TWILIGHT trial treated with the SYNERGY BP-DES or a DP-DES. Following successful PCI and 3 months of ticagrelor plus aspirin, patients were randomized to aspirin or placebo for 1 year; DES choice was at physician discretion. The primary endpoint was target lesion failure (TLF) [composite of cardiac death, target vessel myocardial infarction (MI), clinically driven target lesion revascularization (TLR) or definite/probable stent thrombosis (ST)]. RESULTS: Among enrolled participants (N = 9,006), 653 were treated exclusively with the SYNERGY BP-DES and 6,404 with a comparator DP-DES. Over 15 months, TLF rates were 6.4 and 6.1% among those receiving a SYNERGY BP-DES and a DP-DES, respectively (adjusted HR 0.93; 95% CI 0.64-1.35; p = .72). The effect of ticagrelor monotherapy on Bleeding Academic Research Consortium (BARC) type 2, 3, or 5 bleeding and the composite of all-cause death, MI or stroke was uniform across DES groups (both pint > .10). CONCLUSIONS: The safety and efficacy profile of the SYNERGY BP-DES is comparable to that of contemporary DP-DES in high-risk patients undergoing PCI. Compared to ticagrelor plus aspirin, the effect of ticagrelor monotherapy is consistent among patients receiving SYNERGY BP-DES or DP-DES.

OBJECTIVE: It is still debated if benefits associated with radial versus femoral access for coronary angiography and percutaneous coronary interventions (PCI) are due to the access site selection itself, operator expertise or other underlying mechanisms. METHODS: We searched PubMed, Embase, and meeting abstracts for randomized trials comparing radial versus femoral access site for coronary angiography and PCI. Primary safety endpoint was major bleeding. Coprimary efficacy endpoints were stroke and myocardial infarction (MI). This study is registered with PROSPERO. RESULTS: We identified 31 trials (30,096 patients, PCI performed in 21,225 patients). Radial compared to femoral access was associated with a significant risk reduction in major bleeding (OR 0.53, 95%CI 0.42-0.66, I2 = 3.3%). Findings were consistent regardless of clinical characteristics or whether coronary angiography was performed with or without PCI. The benefit of radial access was significantly increased in studies published before 2010 and in patients with chronic coronary syndrome. Risk for stroke (OR 1.11, 95%CI 0.76-1.64, I2 = 0%) and MI (OR 0.90, 95%CI 0.79-1.04, I2 = 0%) were comparable between the groups. Risk for mortality and vascular complications were significantly lower with radial than femoral access. CONCLUSION: In patients undergoing coronary angiography and PCI, radial access is associated with a significant risk reduction in bleeding, vascular complications, and mortality compared to femoral access. The risk of stroke or MI were comparable in patients with radial or femoral access.

BACKGROUND: Women with acute coronary syndrome (ACS) generally present with more comorbidities and experience worse clinical outcomes compared with males. However, it is unclear whether this represents genuine sex-related difference or stems from clinical, procedural and socioeconomic factors. METHODS: We analyzed consecutive patients undergoing percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI), non-STEMI or unstable angina at a single tertiary-care center. Exclusion criteria were unknown sex, age < 18 years and PCI with bare metal stent or without stent placement. The study population was stratified according to sex. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE) defined as the composite of death, spontaneous myocardial infarction, or stroke at 1 year. Secondary endpoints were individual components of MACCE, target vessel revascularization (TVR) and clinically significant bleeding. RESULTS: Of the 7362 patients included, 5031 (68.3%) were men and 2331 (31.7%) women. Women were older and presented with a higher burden of comorbidities while men had more complex coronary anatomy. The incidence of 1 year MACCE was significantly higher among women (8.0% versus 5.6%; p < 0.01) compared to men. Women also experienced a higher rate of bleeding (2.3% vs. 1.4%; p = 0.02) while there were no differences between groups in terms of TVR (8.1% vs. 7.8%; p-value = 0.83). Differences in outcomes were attenuated after multivariable adjustment. Findings were consistent across ACS subgroups. CONCLUSIONS: In a contemporary ACS population treated with drug-eluting stents, women experienced a higher crude rate of 1-year MACCE. This was no longer apparent after accounting for baseline imbalances.

OBJECTIVE: To investigate the impact of ischemic and bleeding risk factors on long-term clinical outcomes of patients with diabetes mellitus (DM) undergoing percutaneous coronary intervention (PCI) with everolimus-eluting stents. BACKGROUND: Second-generation drug-eluting stents have substantially improved outcomes after PCI in the general population; however, DM patients continue to experience high rates of ischemic and bleeding complications. METHODS: DM patients from the pooled XIENCE V registry were divided into high or low bleeding and ischemic risk groups (HBR, LBR, HIR, and LIR) based on established bleeding (age ≥ 75 years; chronic kidney disease; anemia; prior stroke; oral anticoagulation; thrombocytopenia; prior major bleeding) and ischemic (acute coronary syndrome; prior myocardial infarction [MI]; ≥3 stents implanted; ≥3 vessels treated; ≥3 lesions treated; stent length > 60 mm; bifurcation treated with ≥2 stents; chronic total occlusion) risk factors. The primary outcomes were major adverse cardiac events (MACE; cardiac death, MI, or stent thrombosis) and major bleeding at 4-year follow-up. RESULTS: A total of 3,704 DM patients were divided into four groups (21.5% LBR/LIR; 39.0% LBR/HIR; 15.6% HBR/LIR; 23.9% HBR/HIR). Compared with LBR/LIR patients, those at HBR/HIR and HBR/LIR had a significantly higher risk of MACE (HR (95% CI) 2.7 (1.9-3.9) and 2.2 (1.5-3.2), respectively) and major bleeding (2.7 (1.6-4.8) and 2.6 (1.4-4.7), respectively), while LBR/HIR patients did not. CONCLUSIONS: Among DM patients undergoing PCI, presence of bleeding risk factors was associated with a higher risk of both ischemic and bleeding events, whereas commonly used features of ischemic risk did not impact long-term clinical outcomes.

BACKGROUND: High-sensitivity C-reactive protein (hsCRP) predicts outcomes after percutaneous coronary intervention (PCI). OBJECTIVE: We studied the prevalence and prognostic impact of hsCRP elevation according to age in men and women undergoing PCI. METHODS: We included patients undergoing PCI at our center from 2010 until 2017, excluding those with myocardial infarction (MI) on presentation, neoplastic disease and hsCRP >10 mg/L at baseline. Elevated hsCRP was defined as >3 mg/L. The outcome of interest was major adverse cardiac events (MACE) consisting of all-cause death, MI and target vessel revascularization. The association between hsCRP elevation and outcomes was assessed using adjusted Cox models. RESULTS: 10,432 men and 4,345 women were included. Elevation of hsCRP was present in 25.7% of men and 37.0% of women (p < .01). In men, prevalence of hsCRP elevation was stable across age strata (ptrend = .42). In women, hsCRP elevation was most prevalent in patients <50 years (44.6%) and decreased stepwise with increasing age (ptrend < .001). After stratifying the population into age quartiles (Q1: <59 years, Q2: 59-66 years, Q3: 67-74 years, Q4: ≥75 years), hsCRP elevation was associated with increased risk of MACE across all age groups in men (HR [95% CI] Q1: 1.49 [1.12-1.98]; Q2: 1.51 [1.21-2.06]; Q3: 1.76 [1.27-2.51]; Q4: 1.43[1.03-1.97]). In women, hsCRP elevation was associated with increased risk of MACE only among older patients (HR [95% CI] Q1: 1.08 [0.64-0.82]; Q2: 1.52 [0.93-2.46]; Q3: 1.65 [1.08-2.50]; Q4: 1.52 [1.02-1.28]). CONCLUSION: Among patients undergoing PCI, prevalence and prognostic value of hsCRP elevation were age-dependent exclusively in women.

OBJECTIVES: To describe the incidence, predictors, and clinical impact of permanent pacemaker insertion (PPI) following transcatheter aortic valve replacement (TAVR) in women. BACKGROUND: Data on pacemaker insertion complicating TAVR in women are scarce. METHODS: The Women's International Transcatheter Aortic Valve implantation (WIN-TAVI) is a prospective registry evaluating the safety and efficacy of TAVR in women. We included patients without preprocedural pacemakers and divided them into two groups: (1) PPI and (2) no-PPI. We identified PPI predictors using logistic regression and studied its clinical impact on the Valve Academic Research Consortium (VARC)-2 efficacy and safety endpoints. RESULTS: Out of 1019 patients, 922 were included in the analysis. Post-TAVR PPI occurred in 132 (14.3%) patients. Clinical and procedural characteristics were similar in both groups. Pre-existing right bundle branch block (RBBB) was associated with a high risk of post-TAVR PPI (OR 3.62, 95% CI 1.85-7.06, p < 0.001), while implantation of balloon-expandable prosthesis was associated with a lower risk (OR 0.47, 95% CI 0.30-0.74, p < 0.001). Post-TAVR PPI prolonged in-hospital stay by a median of 2 days (11 [9-16] days in PPI vs. 9 [7-14] days in no-PPI, p = 0.005), yet risks of VARC-2 efficacy and safety endpoints at 1 year were similar in both groups (adj HR 0.95, 95% CI 0.60-1.52, p = 0.84 and adj HR 1.22, 95% CI 0.83-1.79, p = 0.31, respectively). CONCLUSION: Pacemaker implantation following TAVR is frequent among women and is associated with pre-existing RBBB and valve type. PPI prolongs hospital stay, albeit without any significant impact on 1-year outcomes.

OBJECTIVES: To assess the impact of anemia on clinical outcomes in female patients enrolled in the Women's InterNational transcatheter aortic valve implantation (WIN-TAVI) registry. BACKGROUND: Anemia is highly prevalent among females who constitute half of TAVI candidates, yet, its clinical significance remains poorly investigated. METHODS: Patients were divided into three groups according to preprocedural hemoglobin (Hb) level: (1) no anemia (Hb ≥12 g/dl), (2) mild-to-moderate anemia (10 ≤ Hb <12 g/dl), and (3) severe anemia (Hb <10 g/dl). The primary outcome was the occurrence of Valve Academic Research Consortium (VARC)-2 efficacy endpoint, a composite of mortality, stroke, myocardial infarction (MI), hospitalization for valve-related symptoms or heart failure or valve-related dysfunction at 1-year follow-up. RESULTS: Hemoglobin level was available in 877 (86.1%) patients: 412 (47.0%) had no anemia, 363 (41.4%) had mild-to-moderate anemia, and 102 (11.6%) had severe anemia. The latter group had a higher prevalence of cardiovascular risk factors. Compared with patients without anemia, severe anemia was associated with a greater risk of VARC-2 efficacy endpoint (adj HR 1.71, 95% CI: 1.02-2.87, p = .04), all-cause death (adj HR 2.36, 95% CI: 1.31-4.26, p = .004) and a composite of death, MI or stroke (adj HR 1.88, 95% CI: 1.10-3.22, p = .02) at 1 year. Moreover, an increased risk of late mortality (adj HR 1.15, 95% CI: 1.02-1.30, p = .03) was observed with every 1 g/dl decrease in hemoglobin level. CONCLUSION: Severe anemia in females undergoing TAVI was independently associated with increased rates of VARC-2 efficacy endpoint and mortality at 1 year.

PURPOSE: The COMBO biodegradable polymer sirolimus-eluting stent includes endothelial progenitor cell capture (EPC) technology for rapid endothelialization, which may offer advantage in acute coronary syndromes (ACS). We sought to analyze the performance of the COMBO stent by ACS status and ACS subtype. METHODS: The COMBO collaboration (n = 3614) is a patient-level pooled dataset from the MASCOT and REMEDEE registries. We evaluated outcomes by ACS status, and ACS subtype in patients with ST segment elevation myocardial infarction (STEMI) or non-STEMI (NSTEMI) versus unstable angina (UA). The primary endpoint was 1-year target lesion failure (TLF), composite of cardiac death, target vessel myocardial infarction, or clinically driven target lesion revascularization. Secondary outcomes included stent thrombosis (ST). RESULTS: We compared 1965 (54%) ACS and 1649 (46.0%) non-ACS patients. ACS presentations included 40% (n = 789) STEMI, 31% (n = 600) NSTEMI, and 29% (n = 576) UA patients. Risk of 1-year TLF was greater in ACS patients (4.5% vs. 3.3%, HR 1.51 95% CI 1.01-2.25, p = 0.045) without significant differences in definite/probable ST (1.1% vs 0.5%, HR 2.40, 95% CI 0.91-6.31, p = 0.08). One-year TLF was similar in STEMI, NSTEMI, and UA (4.8% vs 4.8% vs. 3.7%, p = 0.60), but definite/probable ST was higher in STEMI patients (1.9% vs 0.5% vs 0.7%, p = 0.03). Adjusted outcomes were not different in MI versus UA patients. CONCLUSIONS: Despite the novel EPC capture technology, COMBO stent PCI was associated with somewhat greater risk of 1-year TLF in ACS than in non-ACS patients, without significant differences in stent thrombosis. No differences were observed in 1-year TLF among ACS subtypes.

Data on ischemic and bleeding outcomes after percutaneous coronary intervention (PCI) in high bleeding risk (HBR) patients with chronic kidney disease (CKD) are scarce. We aimed to evaluate the association between CKD and ischemic and bleeding outcomes in HBR patients who underwent PCI. Among 10,502 patients in the four post-approval registries evaluating patients undergoing PCI, 2,300 patients presented with at least one major or two minor ARC-HBR criteria. CKD was defined as eGFR < 60 mL/min/1.73 m2. These HBR patients were divided into 3 groups: eGFR < 30 mL/min/1.73 m2 defined as severe CKD (N = 221), eGFR 30- < 60 mL/min/1.73 m2 defined as moderate CKD (N = 970), eGFR ≥ 60 mL/min/1.73 m2 defined as no CKD (N = 1,109). The primary endpoint was the composite of cardiac death, myocardial infarction, or stent thrombosis, and the safety endpoint was major bleeding up to 4-year follow-up. HBR patients with CKD were more often female and had higher rates of comorbidities compared to those without CKD. Reduced renal function was associated with higher rates of the primary endpoint (severe CKD vs. moderate CKD vs. no CKD: 30.2% vs. 12.5% vs. 9.1%, P < 0.01) as well as major bleeding (10.3% vs. 8.9% vs. 6.4%, P = 0.03). After adjustment, severe CKD and moderate CKD in HBR patients remained independent predictors for the primary endpoint (HR [95%CI] 2.84 [1.94-4.16], P < 0.01, 1.48 [1.10-2.00], P < 0.01) compared to those with no CKD. However, decreased renal function was no longer significantly associated with major bleeding after adjustment. In conclusions, in HBR patients undergoing PCI, CKD has an important impact on major ischemic events after PCI.

OBJECTIVES: This study sought to investigate the clinical outcomes of patients with and without peripheral artery disease (PAD) in the BRAVO-3 trial with respect to the effect of bivalirudin versus unfractionated heparin (UFH). BACKGROUND: PAD is found frequently in patients undergoing transcatheter aortic valve replacement (TAVR) and is reported to confer an increased risk of adverse events. It is unknown whether patients with and without PAD may demonstrate a differential response to bivalirudin versus UFH. METHODS: BRAVO-3 was a randomized multicenter trial comparing transfemoral TAVR with bivalirudin versus UFH (31 centers, n = 802). Major adverse cardiovascular events (MACE) were a composite of 30-day death, myocardial infarction, or cerebrovascular accidents (CVA). Net adverse cardiovascular events (NACE) were a composite of major bleeding or MACE. RESULTS: The total cohort included 119 patients with PAD. Vascular complications occurred significantly more frequently in patients with PAD both in-hospital (25.2 vs. 16.7%; OR 1.68) and at 30 days (29.4 vs. 17.3%; OR 1.99). No significant differences were observed regarding mortality, NACE, MACE, major bleeding or CVA with bivalirudin versus UFH among patients with or without PAD. In patients with PAD, bivalirudin was associated with an increased risk of minor vascular complications at 30 days. CONCLUSIONS: Patients with PAD undergoing transfemoral TAVR did not exhibit an increased risk of any major adverse events, according to the procedural anticoagulant randomization. However, patients treated with Bivalirudin had significantly higher rates of minor vascular complications.

BACKGROUND: Stroke represents a potentially calamitous complication among patients with acute coronary syndrome (ACS) undergoing percutaneous intervention (PCI). Data on the distribution of stroke occurrence post-PCI and its impact on mortality are scarce. OBJECTIVES: We sought to determine the incidence, predictors and impact of stroke on mortality in ACS patients undergoing PCI. METHODS: A total of 19,914 ACS patients underwent PCI in the PROMETHEUS multicenter observational study. We calculated the cumulative stroke incidence at 30 days and 1 year using the Kaplan Meier method. We also compared the distribution of stroke, myocardial infarction (MI), and bleeding across time and evaluated their overlap. Predictors of stroke were identified through multivariable Cox-regression. Stroke, MI, and bleeding were assessed as time-updated covariates to estimate how each impacts subsequent mortality. RESULTS: We found that 244 patients had a stroke within 1 year, a cumulative incidence of 1.5%. Previous cerebrovascular disease was the strongest predictor for post-PCI stroke, followed by ST-elevation MI presentation, hypertension, non-ST-elevation MI presentation, smoking, female sex, and age. Mortality risk was significantly higher among those who had a stroke versus those who did not (adjusted HR 4.84, p < .0001). However, the association attenuated over time with a much larger effect in the first 30 days of its occurrence (adjusted HR 17.7; 95% CI: 12.3-25.4, p < .0001) versus beyond 30 days (adjusted HR 1.22; 95% CI: 0.6-2.46, p = .58). CONCLUSIONS: Stroke occurrence within 1 year was not uncommon for ACS patients undergoing PCI. When compared with MI and bleeding, stroke had a substantial impact on mortality that attenuated rapidly over time.

BACKGROUND: The prevalence of both chronic kidney disease (CKD) and aortic stenosis (AS) increase with age. Although baseline CKD is frequent in patients undergoing transcatheter aortic valve replacement (TAVR), its significance among women is largely unknown. METHODS: Women's INternational Transcatheter Aortic Valve Implantation (WIN-TAVI) is a multinational, prospective registry of women undergoing TAVR for severe AS. We included patients with available baseline estimated glomerular filtration rate (eGFR) and completed 1-year follow-up. Patients were categorized into three groups based on their eGFR: No CKD (normal kidney function to stage 2 CKD: eGFR ≥60 ml/min/1.73 m2 ); (b) mild CKD (stage 3a CKD: eGFR = 45-59 ml/min/1.73 m2 ); and (c) moderate/severe CKD (stage ≥3b CKD: eGFR <45 ml/min/1.73 m2 ). All events were adjudicated according to the Valve Academic Research Consortium (VARC)-2 criteria. RESULT: Out of 852 women undergoing TAVR, 326 (38.3%) had no CKD, 225 (26.4%) had mild CKD, and 301 (35.3%) had moderate/severe CKD. Women with higher stage of CKD at baseline were more likely to have a history of hypertension, diabetes, atrial fibrillation, anemia, chronic lung disease, hemodialysis, prior percutaneous coronary intervention, and pacemaker implantation. After multivariate adjustment, moderate/severe CKD was associated with a greater risk of 1-year VARC-2 safety endpoints [hazard ratio (HR) 1.68, 95% confidence interval (CI): 1.10-2.60], all-cause death (HR 2.00, 95% CI: 1.03-3.90), and composite of death, myocardial infarction, stroke or life-threatening bleeding (HR 1.70, 95% CI: 1.04-2.76). There were no differences in 30-day and 1-year VARC-2 efficacy and 30-day VARC-2 safety outcomes. CONCLUSION: CKD is associated with substantial and independent risk for mortality and morbidity at 1-year follow-up in women undergoing TAVR.

We sought to investigate the utilization of prasugrel and its association with outcomes relative to clopidogrel in three typical subgroups of ACS in a real-world setting. Prasugrel is superior to clopidogrel for reducing risk of ischemic events in acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI), but is associated with an increased risk of bleeding complications. PROMETHEUS was a retrospective multicenter observational study of 19,913 ACS patients undergoing PCI from 8 centers in the United States between 2010 and 2013. Major adverse cardiovascular events (MACE) were defined as a composite of all-cause mortality, myocardial infarction, stroke or unplanned revascularization. The study cohort included 3285 (16.5%) patients with ST-segment elevation myocardial infarction (STEMI), 5412 (27.2%) patients with NSTEMI and 11,216 (56.3%) patients with unstable angina (UA). The frequency of prasugrel use at discharge was highest in STEMI and lowest in UA patients, 27.3% versus 22.2% versus 18.9% (p < 0.001). Use of prasugrel vs clopidogrel was associated with a lower rate of MACE in STEMI, NSTEMI, or UA at 1 year, but the differences were attenuated for all groups except for patients with UA (adjusted HR 0.81, 95% CI 0.69-0.94, p = 0.006) after propensity adjusted analysis. After adjustment, there was no difference in bleeding risk between prasugrel and clopidogrel for all groups at 1 year. STEMI patients were more likely to receive prasugrel compared to NSTEMI and UA patients. Prasugrel was associated with reduced adverse outcomes compared with clopidogrel in unadjusted analyses, findings that were largely attenuated upon adjustment and suggest preferential use of prasugrel in low vs high risk patients.

Ventricular fibrillation (VF) is a common cause of sudden cardiac death in patients with channelopathies, particularly in the young population. Although pharmacological treatment, cardiac sympathectomy, and implantable cardioverter defibrillators (ICD) have been the mainstay in the management of VF in patients with channelopathies, they are associated with significant adverse effects and complications, leading to poor quality of life. Given these drawbacks, catheter ablation has been proposed as a therapeutic option for patients with channelopathies. Advances in imaging techniques and modern mapping technologies have enabled increased precision in identifying arrhythmia triggers and substrate modification. This has aided our understanding of the underlying pathophysiology of ventricular arrhythmias in channelopathies, highlighting the roles of the Purkinje network and the epicardial right ventricular outflow tract in arrhythmogenesis. This review explores the role of catheter ablation in managing the most common channelopathies (Brugada syndrome, congenital long QT syndrome, short QT syndrome, and catecholaminergic polymorphic ventricular tachycardia). While the initial results for ablation in Brugada syndrome are promising, the long-term efficacy and durability of ablation in different channelopathies require further investigation. Given the genetic and phenotypic heterogeneity of channelopathies, future studies are needed to show whether catheter ablation in patients with channelopathies is associated with a reduction in VF, and psychological distress stemming from recurrent ICD shocks, particularly relative to other available therapeutic options (e.g., quinidine in high-risk Brugada patients).
RESUMEN
Cardiorenal syndrome is a condition where is a bidirectional and mutually detrimental relationship between the heart and kidneys. The mechanisms underlying cardiorenal syndrome are multifactorial and complex. Patients with kidney disease exhibit increased cardiovascular risk, presenting as coronary and peripheral artery disease, structural heart disease, arrhythmias, heart failure, and sudden cardiac death, largely occurring because of a systemic proinflammatory state, causing myocardial and vascular remodeling, manifesting as atherosclerotic lesions, vascular and valvular calcification, and myocardial fibrosis, particularly among those with advanced disease. This review summarizes the current understanding and clinical implications of kidney disease in patients with cardiovascular disease.

INTRODUCTION: Antiplatelet therapy is the cornerstone for prevention and management of ischemic complications among patients with coronary artery disease. Over the past decades, advancement in stent technologies and increasing awareness about the prognostic impact of major bleeding have led to evolving priorities in the management of antithrombotic regimens, from exclusive concerns regarding recurrent ischemic events to an individualized equipoise between ischemic and bleeding risk through a patient-centered comprehensive approach. AREAS COVERED: The purpose of this review is to highlight the current evidence that supports the various management strategies for antiplatelet therapy and discuss future directions of pharmacological regimens for coronary syndromes. We will also discuss the rationale behind use of antiplatelet therapy, current guideline recommendations, risk scores for ischemic and bleeding risk evaluation, and tools to help assess treatment response. EXPERT OPINION: While tremendous advancements have been made in antithrombotic agents and regimens, future directions for antiplatelet therapy in patients with coronary artery disease would involve focus on novel therapeutic targets, development of new antiplatelet agents, implementation of more innovative regimens with current agents and further research to validate contemporary antiplatelet strategies.
