RESUMEN

BACKGROUND: Regarding adjustments to warfarin dosage, numerous studies have shown that computerized methods are superior to those based on personal experience. OBJECTIVES: To report the efficacy of a computer-based warfarin management system (WMS) in the Iranian population. METHODS: By utilizing the existing dosing algorithms and obtaining expert opinions, we developed a computer-based WMS at a large tertiary cardiovascular center. The time in therapeutic range (TTR) and the number of international normalized ratio (INR) tests of clinic patients were compared before and after the implementation of WMS. RESULTS: Overall, 803 patients with 5407 INR tests were included in the before phase and 679 patients with 4189 INR tests in the after phase. The mean TTR was 57.3% before and 59% after WMS implementation (mean difference, 1.64, 95% CI: -1.12 to 4.40). In the before phase, the mean number of INR tests was 6.7, which dropped to 6.1 tests in the after phase (mean difference, -0.61, 95% CI: -0.97 to -0.24). Only 54.5% of the warfarin dosing prescriptions were consistent with the dosing recommendations of the WMS, and adherence to the WMS was poorest in the highest INR target range. CONCLUSIONS: For the first time in Iran, we demonstrated that a computerized system was as effective as a traditional experience-based method to monitor INR in VKA-anticoagulated patients. Furthermore, it could reduce both the number of INR tests and that of visits.

RESUMEN

Fibrinolytic agents catalyze the conversion of the inactive proenzyme plasminogen into the active protease plasmin, degrading fibrin within the thrombus and recanalizing occluded vessels. The history of these medications dates to the discovery of the first fibrinolytic compound, streptokinase, from bacterial cultures in 1933. Over time, researchers identified two other plasminogen activators in human samples, namely urokinase and tissue plasminogen activator (tPA). Subsequently, tPA was cloned using recombinant DNA methods to produce alteplase. Several additional derivatives of tPA, such as tenecteplase and reteplase, were developed to extend the plasma half-life of tPA. Over the past decades, fibrinolytic medications have been widely used to manage patients with venous and arterial thromboembolic events. Currently, alteplase is approved by the U.S. Food and Drug Administration (FDA) for use in patients with pulmonary embolism with hemodynamic compromise, ST-segment elevation myocardial infarction (STEMI), acute ischemic stroke, and central venous access device occlusion. Reteplase and tenecteplase have also received FDA approval for treating patients with STEMI. This review provides an overview of the historical background related to fibrinolytic agents and briefly summarizes their approved indications across various thromboembolic diseases.

RESUMEN

Balancing the safety and efficacy of antithrombotic agents in patients with gastrointestinal disorders is challenging because of the potential for interference with the absorption of antithrombotic drugs and for an increased risk of bleeding. In this Review, we address considerations for enteral antithrombotic therapy in patients with cardiovascular disease and gastrointestinal comorbidities. For those with gastrointestinal bleeding (GIB), we summarize a general scheme for risk stratification and clinical evidence on risk reduction approaches, such as limiting the use of concomitant medications that increase the risk of GIB and the potential utility of gastrointestinal protection strategies (such as proton pump inhibitors or histamine type 2 receptor antagonists). Furthermore, we summarize the best available evidence and potential gaps in our knowledge on tailoring antithrombotic therapy in patients with active or recent GIB and in those at high risk of GIB but without active or recent GIB. Finally, we review the recommendations provided by major medical societies, highlighting the crucial role of teamwork and multidisciplinary discussions to customize the antithrombotic regimen in patients with coexisting cardiovascular and gastrointestinal diseases.

RESUMEN

For most patients, direct oral anticoagulants (DOACs) are preferred over vitamin K antagonists for stroke prevention in atrial fibrillation and for venous thromboembolism treatment. However, randomized controlled trials suggest that DOACs may not be as efficacious or as safe as the current standard of care in conditions such as mechanical heart valves, thrombotic antiphospholipid syndrome, and atrial fibrillation associated with rheumatic heart disease. DOACs do not provide a net benefit in conditions such as embolic stroke of undetermined source. Their efficacy is uncertain for conditions such as left ventricular thrombus, catheter-associated deep vein thrombosis, cerebral venous sinus thrombosis, and for patients with atrial fibrillation or venous thrombosis who have end-stage renal disease. This paper provides an evidence-based review of randomized controlled trials on DOACs, detailing when they have demonstrated efficacy and safety, when DOACs should not be the standard of care, where their safety and efficacy are uncertain, and areas requiring further research.

RESUMEN

OBJECTIVE: The objective of this report is to identify and characterize the relative likelihood of women and racially minoritized pharmacy faculty being promoted, advancing within leadership roles, and earning comparable salaries. METHODS: Data from the 2010-2021 American Association of Colleges of Pharmacy Profile of Pharmacy Faculty surveys were analyzed to compare odds ratios for promotion, leadership roles, and salary gaps of pharmacy faculty according to race and gender. Changes in the odds ratios over time were characterized by linear regression and predictions about when and if equality would be achieved according to current trends were calculated. RESULTS: Compared to White male counterparts, faculty identifying as women, Black, Hispanic, or Asian had a significantly lower odds ratio of promotion to associate or full professor. Women and Asian faculty also had a lower likelihood of promotion from assistant to associate or Chief Executive Officer (CEO) dean. No demographics studied were more likely than White men to advance in rank or attain associate or CEO dean leadership positions. Furthermore, negative salary gaps for women emerge after promotion from assistant professor, becoming significant and continuing to widen at the associate (-$20,419) and CEO dean (-$37,495) level. CONCLUSION: Despite attention to matters of diversity, equity, and inclusion, female and racially minoritized faculty continue to experience lower rates of promotion, leadership advancement, and wages compared to White male colleagues. These results have negative consequences for recruiting and retaining talented faculty and students, and compromise the benefits that a diverse faculty is known to provide on student learning outcomes.

RESUMEN

BACKGROUND: Interleukin-1 blockade with anakinra reduces C-reactive protein (CRP) levels and prevents heart failure (HF) events after ST-segment myocardial infarction (STEMI). The effectiveness of anakinra according to the degree of systemic inflammation in STEMI has not been addressed. METHODS: We analyzed 139 patients from three Virginia Commonwealth University Anakinra Response Trial randomized clinical trials to assess whether CRP levels predicted HF hospitalization or death in patients with STEMI, and if CRP levels influenced the effects of treatment with anakinra. RESULTS: CRP cut-off levels for prediction of the composite of death or HF hospitalization for CRP at admission, 3 and 14 days were, respectively 6.45 mg/L (100% of sensitivity and 66.1% specificity), 26 mg/L (100% of sensitivity and 78% specificity) and 9.56 mg/L (100% of sensitivity and 80% specificity). More patients with elevated CRP levels died or had a HF hospitalization (5/47 [11%] vs 0/82 [0%], p = 0.004 for CRP at admission; 5/32 [15.6%] vs 0/92 [0%], p < 0.001 for day 3 and 5/26 [19%] vs 0/89 [0%], p < 0.001 for day 14). A greater number of patients treated with anakinra had low CRP levels at 3 and 14 days compared to placebo (Odds Ratio 0.11 [95% IC 0.04-0.28], p < 0.0001 and OR 0.35 [95% CI 0.14-0.86], p = 0.02, respectively). Anakinra significantly prevented death or HF hospitalization in patients with high inflammatory burden (p = 0.04 for admission, p = 0.24 for day 3, and p = 0.05 for day 14). CONCLUSION: Patients with elevated CRP had higher incidence of HF hospitalization or death. Anakinra reduced the number of patients with elevated CRP levels and prevented death or HF hospitalization in patients with elevated CRP levels.

RESUMEN

BACKGROUND: Interleukin-1 blockade with anakinra reduces high-sensitivity C-reactive protein (hsCRP) levels and prevents heart failure (HF) events after ST-segment myocardial infarction (STEMI). Sex-based differences in STEMI patients have been reported, but no data are available regarding response to anakinra. METHODS: We analyzed the systemic inflammation and composite end-point of new-onset HF or death in women and men with STEMI treated with anakinra from three different Virginia Commonwealth University Anakinra Response Trial (VCUART) randomized clinical trials. RESULTS: We analyzed 139 patients, 29 (21%) were women while 110 (79%) were men. Baseline hsCRP was higher in women compared to men (8.9 [5.2-13.5] vs. 4.2 [2.1-7.7] mg/L, P<0.001). Eighty-four patients were treated with anakinra (22 [75%] women and 62 [56%] men). The area under the curve of hsCRP (hsCRP-AUC) after 14 days was numerically lower in patients receiving anakinra versus placebo both in men (86 [37-130] vs. 223 [119-374] mg day/L) and in women (73 [46-313] vs. 242 [102-988] mg day/L) (P<0.001 for multiple groups, P for interaction 0.22). The incidence of the composite endpoint was also numerically lower in the anakinra group compared to placebo, both in men (4 [6.4%] vs. 14 [29.1%]) and in women (3 [13.6%] vs. 2 [28.5%]) (P=0.019 for multiple groups, P for interaction 0.44). There were no statistically significant differences between women and men in hsCRP-AUC and death or HF events when comparing separately the anakinra and placebo groups (all P>0.05). CONCLUSIONS: Women were underrepresented in the VCUART trials, they appeared to have higher hsCRP levels at time of presentation, yet to benefit similar to men by treatment with anakinra in STEMI.

RESUMEN

The 1-year incidence of heart failure (HF) after anterior wall ST-elevation acute myocardial infarction (STEMI) remains difficult to determine because of inconsistencies in reporting, definitions, and adjudication. The objective of this study was to evaluate the 1-year incidence of HF after anterior wall STEMI in a real-world data set using a variety of potential criteria and composite definitions. In a retrospective cohort study, anonymized patient data was accessed through a federated health research network (TriNetX Limited Liability Company (LLC)) of 56 US healthcare organizations (US Collaborative Network). Patients were identified based on the International Classification of Diseases, Tenth Revision criteria for anterior wall STEMI during the 10-year period from 2013 to 2022 and the absence of prespecified signs or symptoms of HF. Values for 1-year incidence were calculated as 1 minus Kaplan-Meier survival at 12 months after anterior wall STEMI. Univariate Cox proportional hazard ratio was calculated to compare risk associated with potential risk factors. The analysis utilized 5 different types of definition criteria for HF: Diagnosis codes, Signs and symptoms, Laboratory/imaging, Medications, and Composites. A total of 34,395 patients from the US Collaborative Network met eligibility criteria and were included in the analysis. The 1-year incidence of HF varied from 2% to 30% depending upon the definition criteria. Although no single criteria exceeded a 1-year incidence of 20%, a simple composite of HF diagnosis (International Classification of Diseases, Tenth Revision-I50) or use of loop diuretic produced a 1-year incidence 26.1% that was used as the benchmark outcome for evaluation of risk factors. Age ≥65 years, Black race, low-density lipoprotein ≥100 mg/100 ml, elevated hemoglobin A1c (7% to 9% and >9%), and body mass index≥35 kg/m2 were also associated with increased risk of HF. In conclusion, patients with anterior wall STEMI continue to be at high risk for new-onset HF. In the absence of structured, prospective, systematically adjudicated diagnostic criteria, composite definitions are more likely to yield accurate estimates of HF incidence.

RESUMEN

AIMS: Interleukin-1 (IL-1) blockade may improve exercise capacity in patients with heart failure (HF) patients. The extent of the improvement and its persistence beyond discontinuation of IL-1 blockade is unknown. METHODS AND RESULTS: The primary objective was to determine changes in cardiorespiratory fitness and cardiac function on-treatment with IL-1 blocker, anakinra, and off-treatment, after treatment cessation. We performed cardiopulmonary exercise testing, Doppler echocardiography, and biomarkers in 73 patients with HF, 37 (51%) females, 52 (71%) Black-African-American, before and after treatment with anakinra 100 mg daily. In a subset of 46 patients, testing was also repeated after treatment cessation. Quality of life was assessed in each patient using standardized questionnaires. Data are presented as median and interquartile range. Treatment with anakinra for 4 [2-12] weeks was associated with a significant improvement in high-sensitivity C-reactive protein (from 6.2 [3.3-15.4] to 1.4 [0.8-3.4] mg/L, P < 0.001), peak oxygen consumption (VO2peak , from 13.9 [11.6-16.6] to 15.2 [12.9-17.4] mL/kg/min, P < 0.001). Ventilatory efficiency, exercise time, Doppler-derived signs and biomarkers of elevated intracardiac pressures, and quality-of-life measures also improved with anakinra. In the 46 patients in whom off-treatment data were available 12 [4-12] weeks later, many of the favourable changes seen with anakinra were largely reversed (from 1.5 [1.0-3.4] to 5.9 [1.8-13.1], P = 0.001 for C-reactive protein, and from 16.2 [14.0-18.4] to 14.9 [11.5-17.8] mL/kg/min, P = 0.017, for VO2peak ). CONCLUSIONS: These data validate IL-1 as an active and dynamic modulator of cardiac function and cardiorespiratory fitness in HF.

RESUMEN

Lipoprotein(a), or Lp(a), is structurally like low-density lipoprotein (LDL) but differs in that it contains glycoprotein apolipoprotein(a) [apo(a)]. Due to its prothrombotic and proinflammatory properties, Lp(a) is an independent risk factor for atherosclerotic cardiovascular disease (ASCVD) and aortic valve stenosis. Lp(a) levels are genetically determined, and it is estimated that 20%-25% of the global population has an Lp(a) level ≥50 mg/dL (or ≥125 nmol/L). Diet and lifestyle interventions have little to no effect on Lp(a) levels. Lipoprotein apheresis is the only approved treatment for elevated Lp(a) but is time-intensive for the patient and only modestly effective. Pharmacological approaches to reduce Lp(a) levels and its associated risks are of significant interest; however, currently available lipid-lowering therapies have limited effectiveness in reducing Lp(a) levels. Although statins are first-line agents to reduce LDL cholesterol levels, they modestly increase Lp(a) levels and have not been shown to change Lp(a)-mediated ASCVD risk. Alirocumab, evolocumab, and inclisiran reduce Lp(a) levels by 20-25%, yet the clinical implications of this reduction for Lp(a)-mediated ASCVD risk are uncertain. Niacin also lowers Lp(a) levels; however, its effectiveness in mitigating Lp(a)-mediated ASCVD risk remains unclear, and its side effects have limited its utilization. Recommendations for when to screen and how to manage individuals with elevated Lp(a) vary widely between national and international guidelines and scientific statements. Three investigational compounds targeting Lp(a), including small interfering RNA (siRNA) agents (olpasiran, SLN360) and an antisense oligonucleotide (pelacarsen), are in various stages of development. These compounds block the translation of messenger RNA (mRNA) into apo(a), a key structural component of Lp(a), thereby substantially reducing Lp(a) synthesis in the liver. The purpose of this review is to describe current recommendations for screening and managing elevated Lp(a), describe the effects of currently available lipid-lowering therapies on Lp(a) levels, and provide insight into emerging therapies targeting Lp(a).

RESUMEN

PURPOSE OF REVIEW: This review describes the discovery and development of ACE inhibitors as antihypertensive agents, compares their efficacy, tolerability, and safety to ARBs, and highlights the contemporary issues surrounding ACE inhibitor use for HTN. RECENT FINDINGS: Angiotensin-converting enzyme (ACE) inhibitors are commonly prescribed medications for the management of hypertension (HTN) and other chronic conditions including heart failure and chronic kidney disease. These agents inhibit ACE, the enzyme that is responsible for converting angiotensin (AT) I to AT II. Inhibiting the synthesis of AT II causes arterial and venous vasodilation, natriuresis, and a decrease in sympathetic activity, resulting in the reduction of blood pressure. ACE inhibitors are first-line therapy in HTN management along with thiazide diuretics, calcium channel blockers, and angiotensin receptor blockers (ARB). Along with inhibiting AT II synthesis, inhibition of ACE causes accumulation of bradykinin, increasing the risk of bradykinin-mediated side effects like angioedema and cough. Since ARBs do not work on ACE in the renin-angiotensin system, the risk of angioedema and cough are lower with ARBs. Recent evidence has also suggested ARBs may have neuroprotective effects compared to other antihypertensives, including ACE inhibitors; however, this warrants further study. Currently, ACE inhibitors and ARBs have an equal class of recommendation for first-line treatment for the management of HTN. Recent evidence has shown ARBs to be just as effective as ACE inhibitors for HTN but with improved tolerability.

RESUMEN

INTRODUCTION: No current guidance exists to inform the content area credit hours for doctor of pharmacy (PharmD) programs in the United States (US). METHODS: Public websites were accessed for all Accreditation Council for Pharmacy Education (ACPE) accredited PharmD programs in the US to record the credit hours devoted to drug therapy, clinical skills, experiential learning, scholarship, social and administrative sciences, physiology/pathophysiology, pharmacogenomics, medicinal chemistry, pharmacology, pharmaceutics, and pharmacokinetics/pharmacodynamics in the didactic curricula. Due to the high prevalence of programs that integrate drug therapy, pharmacology, and medicinal chemistry into a single course, we subdivided programs based upon whether drug therapy courses were "integrated" or "non-integrated." A regression analyses was conducted to explore the relationship between each content area and North American Pharmacist Licensure Examination (NAPLEX) pass rates and residency match rates. RESULTS: Data were available for 140 accredited PharmD programs. Drug therapy had the highest credit hours in programs with both integrated and non-integrated drug therapy courses. Programs with integrated drug therapy courses had significantly more credit hours in experiential and scholarship and fewer credit hours in stand-alone courses for pathophysiology, medicinal chemistry, and pharmacology. Credit hours in content areas did not predict NAPLEX pass rate nor residency match success rate. CONCLUSIONS: This is the first comprehensive description of all ACPE accredited pharmacy schools with credit hours broken down by content areas. While content areas did not directly predict success criteria, these results may still be useful to describe curricular norms or inform the design of future pharmacy curricula.

RESUMEN

BACKGROUND: Interleukin-1 blockade with anakinra leads to a transient increase in eosinophil blood count (eosinophils) in patients with acute myocardial infarction. We aimed to investigate the effect of anakinra on changes in eosinophils in patients with heart failure (HF) and their correlation with cardiorespiratory fitness (CRF). METHODS: We measured eosinophils in 64 patients with HF (50% females), 55 (51-63) years of age, before and after treatment, and, in a subset of 41 patients, also after treatment cessation. We also evaluated CRF, measuring peak oxygen consumption (VO2) with a treadmill test. RESULTS: Treatment with anakinra significantly and transiently increased eosinophils, from 0.2 [0.1-0.3] to 0.3 [0.1-0.4] × 103 cells/µL (p < 0.001) and from 0.3 [0.2-0.5] to 0.2 [0.1-0.3] × 103 cells/µL, with suspension (p < 0.001). Changes in eosinophils correlated with the changes in peak VO2 (Spearman's Rho = +0.228, p = 0.020). Eosinophils were higher in patients with injection site reactions (ISR) (n = 8, 13%; 0.5 [0.4-0.6] vs. 0.2 [0.1-0.4] × 103 cells/µL, p = 0.023), who also showed a greater increase in peak VO2 (3.0 [0.9-4.3] vs. 0.3 [-0.6-1.8] mLO2·kg-1·min-1, p = 0.015). CONCLUSION: Patients with HF treated with anakinra experience a transient increase in eosinophils, which is associated with ISR and a greater improvement in peak VO2.

RESUMEN

Ischemia reperfusion injury can lead to further myocardiocyte damage in patients with ST-elevation myocardial infarction (STEMI). Pentoxifylline is a methylxanthine derivative with known anti-inflammatory, antioxidant, vasodilator, and rheological properties which can be a promising agent in preventing reperfusion injury. PENTOS-PCI is a single-center, randomized, double-blind, placebo-controlled trial which evaluated the efficacy and safety of preprocedural administration of intravenous pentoxifylline in patients undergoing primary percutaneous coronary intervention (PCI). Patients with acute STEMI who were eligible for PCI were randomized to receive either 100-mg intravenous infusion of pentoxifylline or placebo, prior to transferring to catheterization laboratory. Overall, 161 patients were included in our study of whom 80 patients were assigned to pentoxifylline and 81 to the control groups. Per-protocol analysis of primary endpoint indexing PCI's success rate as measured by thrombolysis in myocardial infarction (TIMI) flow grade 3 was not significantly different between pentoxifylline and placebo (71.3% and 66.3% respectively, P = 0.40). In addition, pentoxifylline could not improve secondary angiographic endpoints including myocardial blush grade 3 (87.5% and 85.2%, P = 0.79) and corrected TIMI frame count (22.8 [± 9.0] and 24.0 [± 5.1], P = 0.33) in the intervention and placebo groups respectively. The rates of major adverse cardiac and treatment emergent adverse effects were not significantly different between the two groups. Administration of intravenous pentoxifylline before primary PCI did not improve the success rate of the procedure in patients with STEMI. Intravenous administration of pentoxifylline was well tolerated, and there were no significant differences regarding adverse drug reactions in the two groups. Panel A, background: pentoxifylline is a methylxanthine derivative with known anti-inflammatory, antioxidant, vasodilator, and rheological properties which can be a promising agent in preventing reperfusion injury. Panel B: study design and main results of the PENTOS-PCI trial. cTFC corrected TIMI frame count, ED emergency department, IRI ischemia reperfusion injury, MBG myocardial blush grade, PCI percutaneous coronary intervention, PPCI primary PCI, PTX pentoxifylline, ROS reactive oxygen species, SD standard deviation, STEMI ST-elevation myocardial infarction, TIMI thrombolysis in myocardial infarction.

RESUMEN

Anakinra is a recombinant human interleukin-1 receptor antagonist approved for the treatment of inflammatory diseases. Kineret is available as a solution prepared in a borosilicate glass syringe. For implementing a placebo-controlled double-blind randomized clinical trial, anakinra is commonly transferred into plastic syringes. However, there is limited data on anakinra's stability in polycarbonate syringes. We described the results of our previous studies on the use of anakinra in glass (VCUART3) versus plastic syringes (VCUART2) compared with placebo. These studies were conducted in patients with ST-segment elevation myocardial infarction (STEMI), and we assessed the anti-inflammatory effects of anakinra versus placebo by comparing the area under the curve for high-sensitivity cardiac reactive protein (AUC-CRP) levels during the first 14 days of STEMI, its clinical effects on heart failure (HF) hospitalization, cardiovascular death, or new diagnosis of HF as well as adverse events profile between groups. The levels of AUC-CRP were 75 (50-255 mg·day/l) for anakinra in plastic syringes versus 255 (116-592 mg·day/l) in placebo and 60 (24-139 mg·day/l) and 86 (43-123 mg·day/l) for anakinra once and twice daily in glass syringes, respectively, compared with placebo 214 (131-394 mg·day/l). The rate of adverse events was also comparable between groups. There were no differences in the rate of HF hospitalization or cardiovascular death in patients who received anakinra in plastic or glass syringes. Fewer cases of new-onset heart failure occurred in patients receiving anakinra in plastic or glass syringes compared with placebo. Anakinra stored in plastic (polycarbonate) syringes provides comparable biologic and clinical effect to glass (borosilicate) syringes. SIGNIFICANCE STATEMENT: Anakinra (Kineret) 100 mg administered subcutaneously in patients with ST-segment elevation myocardial infarction (STEMI) for a duration of up to 14 days appears to have comparable safety and biological efficacy signals when delivered in prefilled glass or transferred into plastic polycarbonate syringes. This may have important implications for the feasibility of designing clinical trials in STEMI and other clinical conditions.

RESUMEN

BACKGROUND: In the INSPIRATION-S trial, atorvastatin versus placebo was associated with a nonsignificant 16% reduction in 30-day composite of venous/arterial thrombosis or death in intensive care unit (ICU) patients with COVID-19. Thrombo-inflammatory response in coronavirus disease 2019 (COVID-19) may last beyond the first 30 days. METHODS: This article reports the effects of atorvastatin 20 mg daily versus placebo on 90-day clinical and functional outcomes from INSPIRATION-S, a double-blind multicenter randomized trial of adult ICU patients with COVID-19. The main outcome for this prespecified study was a composite of adjudicated venous/arterial thrombosis, treatment with extracorporeal membrane oxygenation (ECMO), or all-cause mortality. Functional status was assessed with the Post-COVID-19 Functional Scale. RESULTS: In the primary analysis, 587 patients were included (age: 57 [Q1-Q3: 45-68] years; 44% women). By 90-day follow-up, the main outcome occurred in 96 (33.1%) patients assigned to atorvastatin and 113 (38.0%) assigned to placebo (hazard ratio [HR]: 0.80, 95% confidence interval [CI]: 0.60-1.05, p = 0.11). Atorvastatin in patients who presented within 7 days of symptom onset was associated with reduced 90-day hazard for the main outcome (HR: 0.60, 95% CI: 0.42-0.86, p interaction = 0.02). Atorvastatin use was associated with improved 90-day functional status, although the upper bound CI crossed 1.0 (ORordinal: 0.64, 95% CI: 0.41-1.01, p = 0.05). CONCLUSION: Atorvastatin 20 mg compared with placebo did not significantly reduce the 90-day composite of death, treatment with ECMO, or venous/arterial thrombosis. However, the point estimates do not exclude a potential clinically meaningful treatment effect, especially among patients who presented within 7 days of symptom onset (NCT04486508).
