Electronic alerts to initiate anticoagulation dialogue in patients with atrial fibrillation.

IMPORTANCE: The benefit of an electronic support system for the prescription and adherence to oral anticoagulation therapy among patients with atrial fibrillation (AF) and atrial flutter at heightened risk for of stroke and systemic thromboembolism is unclear. OBJECTIVE: To evaluate the effect of a combined alert intervention and shared decision-making tool to improve prescription rates of oral anticoagulation therapy and adherence. DESIGN, SETTING, AND PARTICIPANTS: A prospective single arm study of 939 consecutive patients treated at a large tertiary healthcare system. EXPOSURES: An electronic support system comprising 1) an electronic alert to identify patients with AF or atrial flutter, a CHA2DS2-VASc score ≥ 2, and not on oral anticoagulation and 2) electronic shared decision-making tool to promote discussions between providers and patients regarding therapy. MAIN OUTCOMES AND MEASURES: The primary endpoint was prescription rate of anticoagulation therapy. The secondary endpoint was adherence to anticoagulation therapy defined as medication possession ratio ≥ 80% during the 12 months of follow-up. RESULTS: Between June 13, 2018 and August 31, 2018, the automated intervention identified and triggered a unique alert for 939 consecutive patients with AF or atrial flutter, a CHA2DS2-VASc score ≥2 who were not on oral anticoagulation. The median CHA2DS2-VASc score among all patients identified by the alert was 2 and the median untreated duration prior to the alert was 495 days (interquartile range 123 - 1,831 days). Of the patients identified by the alert, 345 (36.7%) initiated anticoagulation therapy and 594 (63.3%) did not: 68.7% were treated with a non-Vitamin K antagonist oral anticoagulant (NOAC), 22.0% with warfarin, and 9.3 % combination of NOAC and warfarin. Compared with historical anticoagulation rates, the electronic alert was associated with a 23.6% increase in anticoagulation prescriptions. The overall 1-year rate of adherence to anticoagulant therapy was 75.4% (260/345). CONCLUSION AND RELEVANCE: An electronic automated alert can successfully identify patients with AF and atrial flutter at high risk for stroke, increase oral anticoagulation prescription, and support high rates of adherence.

Contemporary Medical Therapies for Patients with Peripheral Artery Disease and Concomitant Type 2 Diabetes Mellitus: a Review of Current Evidence.

PURPOSE OF REVIEW: The purpose of this review is to highlight the evidence behind landmark trials involving these two novel drug classes in conjunction with a review of long-standing therapies used to improve cardiovascular (CV) outcomes among patients with peripheral artery disease (PAD) patients and type 2 diabetes mellitus (T2DM). RECENT FINDINGS: Recently, societal guideline recommendations have expanded the management of T2DM to incorporate therapies with CV risk factor modification. This is due to CV outcome trials (CVOT) uncovering advantageous cardioprotective effects of several novel therapies, including glucagon-like peptide-1 receptor agonists (GLP-1 RA) and sodium-glucose cotransporter-2 inhibitors (SGLT2i). Providers who manage high-risk patients with T2DM, such as those with concomitant PAD, are expected to incorporate these novel medical therapies into routine patient care. The body of evidence surrounding GLP-1 RA demonstrates a strong benefit in mitigating the innate heightened CV risk among patients with T2DM. Furthermore, SGLT2i not only have a favorable CV profile but also reduce the risk of HF hospitalizations and progression of renal disease. Patients with T2DM and PAD are known to be at a heightened risk for major adverse cardiac and lower extremity events, heart failure, and chronic kidney disease. As such, the use of novel therapies such as GLP-RA and SGLT2i should be strongly considered to minimize morbidity and mortality in this vulnerable population.

Colchicine in Acute Coronary Syndrome: A Systematic Review.

OBJECTIVE: The purpose of this review is to evaluate the efficacy and safety of colchicine after acute coronary syndrome (ACS). DATA SOURCES: English-language searches were made of MEDLINE and EMBASE from database inception through mid-June 2020. STUDY SELECTION AND DATA EXTRACTION: Randomized trials characterizing the effects of colchicine in ACS were considered. Of 627 title and abstracts identified, nine trials were included. Two reviewers extracted data and rated study quality. DATA SYNTHESIS: Four studies showed colchicine did not attenuate C-reactive protein production. Colchicine did modulate the NOD-like receptor family pyrin domain containing 3 inflammasome in 3 studies and reduced production of chemokine ligand 2 (CCL2), CCL5, and C-X3-C motif chemokine ligand 1 in 1 study. Major adverse cardiovascular events (MACE) were not significantly different at 30 days in 3 studies, administered as 1.8 mg preprocedurally or scheduled 1 mg daily. One study found a significant reduction in MACE with colchicine 0.5 mg daily over median 22.6 months (hazard ratio = 0.77; 95% CI = 0.61-0.96). Colchicine is associated with increased gastrointestinal adverse events but was generally well tolerated. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: Colchicine is likely to reduce MACE in an ACS population if administered for greater than 30 days but does not improve MACE when administered only preprocedurally. CONCLUSIONS: Adjunctive colchicine 0.5 mg daily for greater than 30 days is reasonable for an ACS population on guideline-directed medical therapy treated with PCI. Additional studies are needed to validate and determine the durability of these benefits.
