RESUMEN
BACKGROUND: Early studies on transcatheter aortic valve replacement (TAVR) outcomes showed that female sex was associated with better survival. With increased use of new-generation valves, the impact of sex on contemporary TAVR outcomes is less well known. METHODS: Retrospective analysis using institutional National Cardiovascular Data Registry STS/ACC TVT data was performed on all patients undergoing TAVR at Yale New Haven Hospital from July 2012 to August 2019. New-generation valves were Evolut PRO, Evolut R, and SAPIEN 3. Old-generation valves were CoreValve, SAPIEN, and SAPIEN XT. Log-rank test and Kaplan-Meier curves were used to compare sex differences in survival up to 1 year after TAVR. Cox modeling was used to adjust for baseline and procedural characteristic differences. RESULTS: 927 consecutive patients (41.4% women) underwent TAVR. Women were older (82.8 vs 80.6 years old; p < 0.001) with higher STS mortality scores compared with men (7.6% vs 6.4%; p < 0.001) despite lower prevalence of cardiovascular comorbidities including coronary artery disease, peripheral artery disease, and smoking. Most cases used transfemoral access (90.5%) and new-generation devices (72.3%). Women received smaller valves compared with men (20-26 mm: 78.0% vs 32.9%; 29-34 mm: 22.1% vs 67.1%; overall p < 0.0001). There were no statistically significant differences between sexes in both unadjusted and adjusted 1-year mortality. CONCLUSION: Our data show no significant difference in 1-year survival between sexes using primarily new generation valves. Further studies should reassess the impact of sex on TAVR outcomes and whether newer technologies like new valve design and sizes, and CT imaging may have eliminated sex-based disparities.

Background: Transcatheter aortic valve replacement (TAVR) is known to increase the incidence of conduction disturbances compared to surgical aortic valve replacement; however, there are limited data on the impact and duration of these conduction disturbances on longer term outcomes. Objective: To determine the differential impact of persistent versus nonpersistent new-onset conduction disturbances on TAVR-related complications and outcomes. Methods: This is a single-center retrospective analysis of 927 consecutive patients with aortic stenosis who underwent TAVR at Yale New Haven Hospital from July 2012 to August 2019. Patients with new-onset conduction disturbances within 7 days following TAVR were selected for this study. Persistent and nonpersistent disturbances were, respectively, defined as persisting or not persisting on all patient ECGs for up to 1.5 years after TAVR or until death. Results: Within 7 days after TAVR, conduction disturbances occurred in 42.3% (392/927) of the patients. Conduction disturbances persisted in 150 (38%) patients and did not persist in 187 (48%) patients, and 55 (14%) patients were excluded for having mixed (both persistent and nonpersistent) disturbances. Compared with nonpersistent disturbances, patients with persistent disturbances were more likely to receive a PPM within 7 days after the TAVR procedure (46.0% versus 4.3%, p < 0.001) and had a greater unadjusted 1-year cardiac-related and all-cause mortality risk (HR 2.54, p=0.044 and HR 1.90, p=0.046, respectively). Conclusion: Persistent conduction disturbances were associated with a greater cardiac and all-cause mortality rate at one year following TAVR. Future research should investigate periprocedural factors to reduce persistent conduction disturbances and outcomes beyond one year follow-up.

OBJECTIVE: To evaluate the effect of colchicine and high-intensity rosuvastatin in addition to standard of care on the progression of COVID-19 disease in hospitalised patients. DESIGN: A pragmatic, open-label, multicentre, randomised controlled trial conducted from October 2020 to September 2021. Follow-up was conducted at 30 and 60 days. The electronic medical record was used at all stages of the trial including screening, enrolment, randomisation, event ascertainment and follow-up. SETTING: Four centres in the Yale New Haven Health System. PARTICIPANTS: Non-critically ill hospitalised patients with COVID-19. INTERVENTIONS: Patients were randomised 1:1 to either colchicine plus high-intensity rosuvastatin in addition to standard of care versus standard of care alone. Assigned treatment was continued for the duration of index hospitalisation or 30 days, whichever was shorter. PRIMARY AND SECONDARY OUTCOME MEASURES: The prespecified primary endpoint was progression to severe COVID-19 disease (new high-flow or non-invasive ventilation, mechanical ventilation, need for vasopressors, renal replacement therapy or extracorporeal membrane oxygenation, or death) or arterial/venous thromboembolic events (ischaemic stroke, myocardial infarction, deep venous thrombosis or pulmonary embolism) evaluated at 30 days. RESULTS: Among the 250 patients randomised in this trial (125 to each arm), the median age was 61 years, 44% were women, 15% were Black and 26% were Hispanic/Latino. As part of the standard of care, patients received remdesivir (87%), dexamethasone (92%), tocilizumab (18%), baricitinib (2%), prophylactic/therapeutic anticoagulation (98%) and aspirin (91%). The trial was terminated early by the data and safety monitoring board for futility. No patients were lost to follow-up due to electronic medical record follow-up. There was no significant difference in the primary endpoint at 30 days between the active arm and standard of care arm (15.2% vs 8.8%, respectively, p=0.17). CONCLUSIONS: In this small, open-label, randomised trial of non-critically ill hospitalised patients with COVID-19, the combination of colchicine and rosuvastatin in addition to standard of care did not appear to reduce the risk of progression of COVID-19 disease or thromboembolic events, although the trial was underpowered due to a lower-than-expected event rate. The trial leveraged the power of electronic medical records for efficiency and improved follow-up and demonstrates the utility of incorporating electronic medical records into future trials. TRIAL REGISTRATION: NCT04472611.

BACKGROUND/PURPOSE: The prevalence of dementia and aortic stenosis (AS) increases with each decade of age. Transcatheter aortic valve replacement (TAVR) is a definitive treatment for AS, but there are scarce data on morbidity, mortality, and readmission risk after TAVR in patients with dementia. METHODS/MATERIALS: We identified all admissions for TAVR in patients with AS in the National Readmissions Database in 2017-2018 and stratified them according to the presence or absence of a secondary diagnosis of dementia. Inpatient outcomes were compared using logistic regression. Cox proportional-hazards models were used to compare 30-, 60-, and 90-day readmissions. RESULTS: A total of 48,923 index hospitalizations for TAVR were identified, of which 2192 (4.5 %) had a secondary diagnosis of dementia. Presence of dementia was associated with higher odds of delirium, pacemaker placement, acute kidney injury, and fall in hospital. The hazard of 30-day readmission was not significantly different between patients with and without dementia, but patients with dementia experienced a higher hazard of 60-day readmission (HR 1.15, 95 % CI 1.03-1.26, p = 0.011) in the unadjusted model and higher hazard of 90-day readmission in both unadjusted (HR 1.18, 95 % CI 1.08-1.30, p < 0.001) and adjusted models (aHR 1.14, 95 % CI 1.04-1.25, p = 0.004). CONCLUSIONS: Patients with dementia who undergo TAVR are at higher risk of in-hospital adverse outcomes and 60- and 90-day readmissions compared with patients without dementia. These estimates should be integrated into shared decision-making discussions with patients and families.

OBJECTIVES: We sought to examine readmission rates and predictors of hospital readmission following TAVR in patients with ESRD. BACKGROUND: End-stage renal disease (ESRD) is associated with poor outcomes following transcatheter aortic valve replacement (TAVR). METHODS: We assessed index hospitalizations for TAVR from the National Readmissions Database from 2017 to 2018 and used propensity scores to match those with and without ESRD. We compared 90-day readmission for any cause or cardiovascular cause. Length of stay (LOS), mortality, and cost were assessed for index hospitalizations and 90-day readmissions. Multivariable logistic regression was performed to identify predictors of 90-day readmission. RESULTS: We identified 49,172 index hospitalizations for TAVR, including 1,219 patients with ESRD (2.5%). Patient with ESRD had higher rates of all-cause readmission (34.4% vs. 19.2%, HR 1.96, 95% CI 1.68-2.30, p<0.001) and cardiovascular readmission (13.2% vs. 7.7%, HR 1.85, 95% CI 1.44-2.38, p<0.001) at 90 days. During index hospitalization, patients with ESRD had longer length of stay (mean difference 1.9 days), increased hospital cost (mean difference $42,915), and increased in-hospital mortality (2.6% vs. 0.9%). Among those readmitted within 90 days, patients with ESRD had longer LOS and increased hospital charge, but similar in-hospital mortality. Diabetes (OR 1.86, 95% CI 1.31-2.64) and chronic pulmonary disease (OR 1.51, 95% CI 1.04-2.18) were independently associated with higher odds of 90-day readmission in patients with ESRD. CONCLUSION: Patients with ESRD undergoing TAVR have higher mortality and increased cost associated with their index hospitalization and are at increased risk of readmission within 90 days following TAVR.

Isolated coronary artery ectasia (CAE) is a relatively rare clinical entity, the pathogenesis of which is poorly understood. More and more evidence is accumulating to suggest a critical inflammatory component. We aimed to elucidate any association between neutrophil to lymphocyte ratio and coronary artery ectasia. A systematic MEDLINE database, ClinicalTrials.gov, medRxiv, Scopus and Cochrane Library search was conducted: 50 studies were deemed relevant, reporting on difference in NLR levels between CAE patients and controls (primary endpoint) and/or on high-sensitive CRP, IL-6, TNF-a and RDW levels (secondary endpoint), and were included in our final analysis. (PROSPERO registration number: CRD42021224195). All inflammatory biomarkers under investigation were found higher in coronary artery ectasia patients as compared to healthy controls (NLR; SMD = 0.73; 95% CI: 0.27-1.20, hs-CRP; SMD = 0.96; 95% CI: 0.64-1.28, IL-6; SMD = 2.68; 95% CI: 0.95-4.41, TNF-a; SMD = 0.50; 95% CI: 0.24-0.75, RDW; SMD = 0.56; 95% CI: 0.26-0.87). The main limitations inherent in this analysis are small case-control studies of moderate quality and high statistical heterogeneity. Our findings underscore that inflammatory dysregulation is implicated in coronary artery ectasia and merits further investigation.
RESUMEN
Background: The Supreme healing-targeted drug-eluting stent (DES) is designed to promote endothelial healing to reduce stent-related adverse events. This may be particularly relevant among complex lesions that have a higher rate of adverse events. We sought to compare 1-year outcomes of percutaneous coronary intervention in complex lesions between the Supreme DES and contemporary durable-polymer, everolimus-eluting stents (DP-EES). Methods: PIONEER III was a multicenter, prospective, single-blind clinical trial, randomizing 1629 patients with either an acute or chronic coronary syndrome in a 2:1 ratio to the Supreme DES or DP-EES. Complex lesions (American College of Cardiology/American Heart Association type B2/C) were found in 1137 patients. Outcomes were also compared for specific parameters of lesion complexity: severe calcification, long length (>20 âmm), and severe tortuosity. The primary end point was target lesion failure at 1 âyear. Results: At 1 âyear, there was no difference in target lesion failure between the Supreme DES and DP-EES: (5.7% vs 5.6%; hazard ratio 1.00, 95% confidence interval 0.59-1.68, P = .99). Similarly, there were no differences in the secondary end points of lesion success (99.7% vs 99.4%, P = .41), device success (97.0% vs 98.5%, P = .14), target vessel failure (6.5% vs 7.4%, P = .50), major adverse cardiac events (7.8% vs 8.5%, P = .64), or stent thrombosis (0.7% vs 1.1%, P = .48). A trend was observed toward a higher rate of target lesion revascularization with the Supreme DES (2.5% vs 0.9%, P = .06). Conclusions: This study suggests that the Supreme DES is as effective and safe at 1 âyear compared with the standard DP-EES across a broad spectrum of lesion complexity.
RESUMEN
BACKGROUND: Despite improvement in the standard of care (SOC) for hospitalized COVID-19 patients, rates of morbidity and mortality remain high. There continues to be a need for easily available and cost-effective treatments. Colchicine and rosuvastatin are both safe and well-studied medications with anti-inflammatory and other pleiotropic effects that may provide additional benefits to hospitalized COVID-19 patients. METHODS AND RESULTS: The Colchicine/Statin for the Prevention of COVID-19 Complications (COLSTAT) trial is a pragmatic, open-label, multicenter, randomized trial comparing the combination of colchicine and rosuvastatin in addition to SOC to SOC alone in hospitalized COVID-19 patients. Four centers in the Yale New Haven Health network will enroll a total of 466 patients with 1:1 randomization. The trial will utilize the electronic health record (Epic® Systems, Verona, Wisconsin, USA) at all stages including screening, randomization, intervention, event ascertainment, and follow-up. The primary endpoint is the 30-day composite of progression to severe COVID-19 disease as defined by the World Health Organization ordinal scale of clinical improvement and arterial/venous thromboembolic events. The secondary powered endpoint is the 30-day composite of death, respiratory failure requiring intubation, and myocardial injury. CONCLUSIONS: The COLSTAT trial will provide evidence on the efficacy of repurposing colchicine and rosuvastatin for the treatment of hospitalized COVID-19 patients. Moreover, it is designed to be a pragmatic trial that will demonstrate the power of using electronic health records to improve efficiency and enrollment in clinical trials in an adapting landscape.

The global burden of atrial fibrillation (AF) is constantly increasing, necessitating novel and effective therapeutic options. Sodium glucose co-transporter 2 (SGLT2) inhibitors have been introduced in clinical practice as glucose-lowering medications. However, they have recently gained prominence for their potential to exert substantial cardiorenal protection and are being evaluated in large clinical trials including patients with type 2 diabetes and normoglycemic adults. In this review we present up-to-date available evidence in a pathophysiology-directed manner from cell to bedside. Preclinical and clinical data regarding a conceivable antiarrhythmic effect of SGLT2 inhibitors are beginning to accumulate. Herein we comprehensively present data that explore the potential pathophysiological link between SGLT2 inhibitors and AF. With regard to clinical data, no randomized controlled trials evaluating SGLT2 inhibitors effects on AF as a pre-specified endpoint are available. However, data from randomized controlled trial post-hoc analysis as well as observational studies point to a possible beneficial effect of SGLT2 inhibitors on AF. Meta-analyses addressing this question report inconsistent results and the real magnitude of AF prevention by SGLT2 inhibition remains unclear. Still, while (i) pathophysiologic mechanisms involved in AF might be favorably affected by SGLT2 inhibitors and (ii) emerging, yet inconsistent, clinical data imply that SGLT2 inhibitor-mediated cardiorenal protection could also exert antiarrhythmic effects, the argument of whether these novel drugs will reduce AF burden is unsettled and mandates appropriately designed and adequately sized randomized controlled studies.

Colchicine's medical evolution is historically bound to the Mediterranean basin, since remarkable researchers from this region underscored its valuable properties. With the passing of years colchicine became an essential pharmaceutical substance for the treatment of rheumatologic and cardiovascular diseases. In light of recent findings, the therapeutic value of colchicine has grown. In clinical practice, colchicine remains underutilized in view of its proven efficacy and safety. Its complex pharmacokinetics and multifaceted anti-inflammatory role remain under investigation. The current review addresses the safe administration of colchicine in view of key drug to drug interactions. Finally, we are briefly presenting colchicine's future potential applications.
RESUMEN
Atrial fibrillation (AF) and diabetes mellitus (DM) are commonly encountered in clinical practice. Although, the long term macrovascular and microvascular sequela of DM are well validated, the association between the less prevalent type 1 DM (T1DM) and atrial arrhythmogenesis is poorly understood. In the present review we highlight the current experimental and clinical data addressing this complex interaction. Animal studies support that T1DM, characterized by insulin deficiency and glycemic variability, impairs phosphatidylinositol 3kinase (PI3K)/protein kinase B signaling pathway. This pathway holds a central role in atrial electrical and structural remodeling responsible for arrhythmia initiation and maintenance. The molecular ''footprint'' of T1DM in atrial myocytes seems to involve a state of increased oxidative stress, impaired glucose transportation, ionic channel dysregulation and eventually fibrosis. On the contrary only a few clinical studies have examined the role of T1DM as an independent risk factor for AF development, and are discussed here. Further research is needed to solidify the real magnitude of this association and to investigate the clinical implications of PI3K molecular signaling pathway in atrial fibrillation management.

BACKGROUND: Acute myocardial infarction (MI) is a major clinical manifestation of coronary artery disease. Post-MI morbidity and mortality can be reduced by lifestyle changes and aggressive risk factor modification. These changes can be applied more effectively if the patient is actively involved in the process. The hypothesis of this study was that an educational programme in post-MI patients could lead to reduced incidence of cardiovascular events. METHODS: Post-MI patients were prospectively randomised into two groups. Patients in the intervention arm were scheduled to attend an 8-week-long educational programme on top of usual treatment, while controls received optimal treatment. The primary endpoint was the composite of all-cause death, MI, cerebrovascular event and unscheduled hospitalisation for cardiovascular causes. Endpoint adjudication was blinded. RESULTS: 329 patients (238 men) were included, with a mean follow-up time of 17±4 months. In the primary analysis, mean primary end point-free survival time was 597 days (95% CI 571 to 624) in controls, compared with 663 days (95% CI 638 to 687) in the intervention group (p<0.001). The HR in the univariate Cox regression analysis was 0.48 (95% CI 0.32 to 0.73; p=0.001). The raw rates of the primary endpoint were 20.8% (6 deaths, 13 MIs, 2 strokes and 14 hospitalisations) vs 36.6% (8 deaths, 22 MIs, 7 strokes and 22 hospitalisations), respectively (OR 0.46, 95% CI 0.28 to 0.74; p=0.002). CONCLUSION: These results suggest that a relatively short adult education programme offered to post-MI patients has beneficial effects, resulting in reduced risk of cardiovascular events.

Importance: Severe acute respiratory syndrome coronavirus 2 infection has evolved into a global pandemic. Low-dose colchicine combines anti-inflammatory action with a favorable safety profile. Objective: To evaluate the effect of treatment with colchicine on cardiac and inflammatory biomarkers and clinical outcomes in patients hospitalized with coronavirus disease 2019 (COVID-19). Design, Setting, and Participants: In this prospective, open-label, randomized clinical trial (the Greek Study in the Effects of Colchicine in COVID-19 Complications Prevention), 105 patients hospitalized with COVID-19 were randomized in a 1:1 allocation from April 3 to April 27, 2020, to either standard medical treatment or colchicine with standard medical treatment. The study took place in 16 tertiary hospitals in Greece. Intervention: Colchicine administration (1.5-mg loading dose followed by 0.5 mg after 60 min and maintenance doses of 0.5 mg twice daily) with standard medical treatment for as long as 3 weeks. Main Outcomes and Measures: Primary end points were (1) maximum high-sensitivity cardiac troponin level; (2) time for C-reactive protein to reach more than 3 times the upper reference limit; and (3) time to deterioration by 2 points on a 7-grade clinical status scale, ranging from able to resume normal activities to death. Secondary end points were (1) the percentage of participants requiring mechanical ventilation, (2) all-cause mortality, and (3) number, type, severity, and seriousness of adverse events. The primary efficacy analysis was performed on an intention-to-treat basis. Results: A total of 105 patients were evaluated (61 [58.1%] men; median [interquartile range] age, 64 [54-76] years) with 50 (47.6%) randomized to the control group and 55 (52.4%) to the colchicine group. Median (interquartile range) peak high-sensitivity cardiac troponin values were 0.0112 (0.0043-0.0093) ng/mL in the control group and 0.008 (0.004-0.0135) ng/mL in the colchicine group (P = .34). Median (interquartile range) maximum C-reactive protein levels were 4.5 (1.4-8.9) mg/dL vs 3.1 (0.8-9.8) mg/dL (P = .73), respectively. The clinical primary end point rate was 14.0% in the control group (7 of 50 patients) and 1.8% in the colchicine group (1 of 55 patients) (odds ratio, 0.11; 95% CI, 0.01-0.96; P = .02). Mean (SD) event-free survival time was 18.6 (0.83) days the in the control group vs 20.7 (0.31) in the colchicine group (log rank P = .03). Adverse events were similar in the 2 groups, except for diarrhea, which was more frequent with colchicine group than the control group (25 patients [45.5%] vs 9 patients [18.0%]; P = .003). Conclusions and Relevance: In this randomized clinical trial, participants who received colchicine had statistically significantly improved time to clinical deterioration. There were no significant differences in high-sensitivity cardiac troponin or C-reactive protein levels. These findings should be interpreted with caution. Trial Registration: ClinicalTrials.gov Identifier: NCT04326790.

OBJECTIVE: Colchicine has been utilized safely in a variety of cardiovascular clinical conditions. Among its potential mechanisms of action is the non-selective inhibition of NLRP3 inflammasome which is thought to be a major pathophysiologic component in the clinical course of patients with COVID-19. GRECCO-19 will be a prospective, randomized, open-labeled, controlled study to assess the effects of colchicine in COVID-19 complications prevention. METHODS: Patients with laboratory confirmed SARS-CoV-2 infection (under RT PCR) and clinical picture that involves temperature >37.5 oC and at least two out of the: i. sustained coughing, ii. sustained throat pain, iii. Anosmia and/or ageusia, iv. fatigue/tiredness, v. PaO2<95 mmHg will be included. Patients will be randomised (1:1) in colchicine or control group. RESULTS: Trial results will be disseminated through peer-reviewed publications and conference presentations. CONCLUSION: GRECCO-19 trial aims to identify whether colchicine may positively intervene in the clinical course of COVID-19. (ClinicalTrials.gov Identifier: NCT04326790).

BACKGROUND: Recent reports describe increases in the case volume of surgical aortic valve replacement (SAVR) after centers establish a transcatheter aortic valve replacement (TAVR) program. We investigate contemporary temporal trends in SAVR and TAVR case volumes and risk profiles at a high volume academic medical center. METHODS: We conducted a retrospective, descriptive evaluation of consecutive patients who underwent TAVR (n = 538) or SAVR (n = 657) in 2011-2016. The STS predicted risk of mortality (PROM) for isolated SAVR was used to calculate PROM for both SAVR and TAVR patients. Patients were stratified based on STS PROM as follows: low risk (<4%), intermediate risk (4-8%), and high risk (≥8%). Temporal changes in patient risk-profile were characterized descriptively. RESULTS: Median STS PROM for the study period was 6.3% and 2.0% for TAVR and SAVR cohorts, respectively (P < 0.001). Since 2011, TAVR volume consistently increased, while SAVR volume increased initially, peaking in 2013 and steadily declined. The STS PROM for SAVR remained stable during the entire study period, while that for TAVR showed a steady decline. The proportions of intermediate and low STS PROM patients undergoing TAVR increased. Proportions of each risk category in SAVR cohort remained stable over time. CONCLUSIONS: SAVR volume increased initially but declined eventually following the implementation of TAVR program. The distribution of the STS PROM in TAVR cohort changed dramatically with increasing proportion of patients in lower risk categories. These findings suggest the converging patient populations in TAVR and SAVR, which may be associated with the decline in the overall SAVR volume.

OBJECTIVES: The present study was designed to assess whether the incidence and outcomes of VSR-AMI have changed in the era of timely primary PCI. BACKGROUND: Ventricular septal rupture (VSR) is a rare but frequently fatal complication of acute myocardial infarction (AMI). METHODS: We conducted a retrospective cohort study of all Medicare fee-for-service beneficiaries from 1999 to 2014 to examine trends in the incidence, surgical and percutaneous repair, and 30-day and 1-year mortality of VSR-AMI. RESULTS: The annual incidence of VSR-AMI hospitalization declined by 41.6% from 197 patients per 100,000 AMIs in 1999 to 115 patients per 100,000 AMIs in 2014 (P < 0.001). The 30-day VSR-AMI repair rate decreased from 49.9% in 1999 to 33.3% in 2014 (P < 0.001). In 2014, 82.9% of repairs were performed surgically and 17.1% percutaneously. VSR-AMI mortality rates were high (60.2% at 30 days; 68.5% at 1 year) and changed minimally over the study period with adjusted 30-day mortality per year Odds Ratio (OR) 0.99 (95% confidence interval [CI] 0.98-1.01) and adjusted 1-year mortality per year OR 0.98 (95% CI 0.97-1.00). Across the 16 years of data, unadjusted mortality rates were lower in patients undergoing repair than in unrepaired patients at 30 days (mean 51.7% and 65.7%, P ≤ 0.01) and 1 year (mean 62.0% and 72.8%, P < 0.01). CONCLUSIONS: In the era of increased timely primary PCI, the incidence of VSR-AMI hospitalization declined but its associated mortality rate remained high. Rates of VSR repair decreased from 1999 to 2014 despite increased use of percutaneous repair.

Peripheral arterial disease is a major cause of morbidity and disability and has been consistently associated with an adverse overall prognosis. Oxidative stress has been linked to vascular disease, with several suggested pathogenetic mechanisms, leading to various insults of the arterial wall and, ultimately, to atherothrombotic disease. Considering that the pathophysiological background is quite compelling, attenuation of oxidative processes by means of various substances with antioxidant properties has been conceived as a promising therapeutic target. However, clinical results have been mostly disappointing and 'antioxidant' therapies are still far from being integrated into treatment algorithms for vascular disease.
