RESUMEN
Patients with peripheral artery disease (PAD) experience major cardiovascular and limb events. Antithrombotic strategies including antiplatelets and anticoagulants remain a cornerstone of treatment and prevention. Recent trials have shown heterogeneity in the response to antithrombotic therapies in patients presenting primarily with PAD when compared to those presenting primarily with coronary artery disease. In addition, there is observed heterogeneity with regards to the effects of antiplatelets and anticoagulants with respect to different outcomes including cardiovascular and major adverse limb events. This, coupled with risks of bleeding, requires a patient-centered and holistic assessment of benefit-risk when selecting antithrombotic strategies for patients with PAD. A global multidisciplinary work group was convened to evaluate antithrombotic strategies in PAD and to summarize the current state of the art. Common clinical scenarios around antithrombotic decision making were provided. Finally, insights with regard to implementation future investigation were described.

Venous thromboembolism (VTE) is a common vascular condition. New medications are available to prevent hospital-associated VTE. Strategies are being studied to increase appropriate diagnostic testing utilization. Management of deep vein thrombosis (DVT) and pulmonary embolism (PE) has evolved with the advent of new anticoagulant options and catheter-directed intervention. In light of this, providers are commonly challenged with the decision regarding inpatient versus outpatient management. Which patients require long-term (> 3 months) anticoagulation is challenging and multiple clinical prediction models may be used to help determine the risk-benefit ratio in each patient. The management of VTE is an ongoing area of research and is rapidly evolving.

Management of intermediate and high risk acute pulmonary embolism (PE) is challenging. The role of multidisciplinary teams for the care of these patients is emerging. Herein, we report our experience with a pulmonary embolism response team (PERT). We conducted a retrospective chart review on all patients admitted to the Cleveland Clinic main campus who required activation of the (PERT) from October 1, 2014 to September 1, 2016. We extracted data pertaining to clinical presentation, bleeding complications, and pre- and post-discharge imaging. Patients were classified as low, intermediate or high risk PE. Descriptive and continuous variables were collected and analyzed. There were 134 PERT activations. PE was confirmed by CT-PA in 118 patients. Fifteen (13%) patients were classified as low risk, 80 (68%) intermediate risk PE and 23 (19%) high risk PE. Fourteen (12%) patients were treated with catheter directed rtPA, 6 (5%) received full dose (100 mg rtPA), 16 (13%) received systemic half-dose (50 mg rtPA), 6 (5%) underwent a surgical embolectomy and 4 (3%) underwent mechanical thrombectomy. 65 (55%) patients received anticoagulation only, and 8 (7%) patients were managed conservatively without any anticoagulation or advanced therapy. 11 (9%) patients died while during the hospitalization. Fourteen patients had major bleeding events. There were no bleeding events among patients who received systemic low dose or full dose rtPA. A multidisciplinary approach to cases of intermediate risk and high risk PE can be implemented successfully. We saw a relatively low rate of bleeding events with use of rtPA.

BACKGROUND: We present a case series of upper extremity fibromuscular dysplasia (UE FMD) consisting of 22 patients from two tertiary referral centers focusing on clinical presentation, diagnostic findings, and interventional outcomes. FMD is a noninflammatory, nonatherosclerotic arteriopathy that has a predisposition for middle-aged women. Involvement of the UE is thought to be rare. Patients with UE FMD can present with claudication or ischemia, or they can be incidentally diagnosed. The treatment approach is dictated by clinical presentation. METHODS: Data were collected of patients with UE FMD evaluated at two centers. Demographic data, presenting UE symptoms, UE arteries involved, FMD type, diagnostic method, physical examination findings, management, and outcomes were included. RESULTS: Twenty-two patients (29 limbs) were diagnosed with UE FMD. The brachial artery was most commonly involved (89.7% of affected limbs). More than half of limbs (n = 15 of 29 limbs [51.7%]) were asymptomatic, and of those who presented with symptoms, the most common symptoms were ischemic fingers or hand (31% of all affected limbs) and hand or arm claudication (27.6% of all affected limbs). UE FMD was noted on catheter angiography in 58.6% (n = 17 of 29 limbs), duplex ultrasound in 41.4% (n = 12 of 29 limbs), and computed tomography angiography in 27.6% (n = 8 of 29 limbs). Of the symptomatic limbs (n = 14), the majority were treated solely with medical therapy as the first intervention (57.1%). For symptomatic limbs treated with vascular intervention (n = 5), angioplasty was most commonly performed. Only 4 of the 14 limbs (28.6%) had complete symptomatic relief after the initial first intervention, in which 2 limbs were treated with medical therapy, 1 limb underwent angioplasty, and 1 limb had resolution of symptoms despite deferment of any therapy. Of the 10 limbs with residual symptoms after the first intervention, 6 limbs underwent a second intervention: angioplasty in 2 limbs initially treated medically (33.3%), surgical bypass in 2 limbs initially treated with angioplasty, surgical bypass in 1 limb initially treated with medical therapy, and sympathectomy in 1 limb (16.7%) initially treated with angioplasty. Both surgical bypass and angioplasty as secondary interventions resulted in complete symptom relief. CONCLUSIONS: Presenting symptoms for patients with UE FMD vary in severity from asymptomatic disease to digital ischemia. More than half of symptomatic limbs eventually require at least one invasive intervention for complete relief of symptoms.

Pulmonary embolism (PE) is a common thrombotic event that is variable in its presentation. Depending on the patients' risk for mortality, guidelines provide several treatment strategies including thrombolysis, catheter-directed therapies, pulmonary embolectomy, anticoagulation, and inferior vena cava filters. However, there is considerable disagreement between guidelines regarding the optimal treatment strategy for patients, particularly for those with intermediate-risk PE. In order to provide rapid and individualized care, PE response teams (PERT) have been developed. These teams consist of members from different specialties with a particular interest in PE, varying technical skills, and clinical experience, thereby allowing for a multidisciplinary approach. PERT allows for consensus decision making, and for rapid intervention in patients whose conditions worsen. In this review, we provide an overview of treatment guidelines for PE, and of results from recent clinical trials involving patients with submassive PE. In addition, we discuss an outline of our approach and use of PERT.

OPINION STATEMENT: Fibromuscular dysplasia (FMD) is an arteriopathy of unknown etiology which has traditionally been associated with secondary hypertension; however, it has garnered increased attention in the cardiology field in the recent years because of its potential association with spontaneous coronary artery dissection. Cardiologists should be aware that FMD is a polyvascular disease which can affect any arterial bed and can result in morbid conditions such as chronic headaches, pulsatile tinnitus, stroke from cervical artery dissection, and renal infarction from renal artery dissection and has also been associated with increased prevalence of arterial aneurysm, including brain aneurysm. For these reasons, some experts recommend panvascular imaging from head-to-pelvis upon diagnosis for screening purposes and targeted imaging surveillance after diagnosis. When necessary, endovascular intervention with angioplasty alone is the preferred modality, though there are still situations which require surgical intervention. Patients with FMD may benefit from a multispecialty team approach for optimal treatment.

INTRODUCTION: K201, a 1,4-benzodiazepine derivative, acts on multiple cardiac ion channels and the ryanodine receptor. We tested whether administration of M-II, the main metabolite of K201, would terminate induced atrial flutter (AFL) or atrial fibrillation (AF) in the canine sterile pericarditis model. METHODS: In 6 dogs, electrophysiologic studies were performed at baseline and after drug administration, measuring atrial effective refractory period (AERP), and conduction time from 3 sites during pacing at cycle lengths (400, 300, and 200 milliseconds) on postoperative days 1-4. In 12 induced episodes of sustained AF/AFL (2/10, respectively), M-II was administered intravenously to test efficacy. Five of the AFL episodes were studied in the open chest state during simultaneous multisite atrial mapping. RESULTS: M-II terminated 2/2 AF and 8/10 AFL episodes, prolonged AERP (P < 0.05), significantly increased atrial pacing capture thresholds but did not significantly change atrial conduction time. AFL CL prolongation was largely explained by prolonged conduction in an area of slow conduction in the reentrant circuit. AFL terminated with block in the area of slow conduction. CONCLUSIONS: M-II was very effective in terminating AFL/AF in the canine sterile pericarditis model. AFL terminated due to block in the area of slow conduction of the reentrant circuit.

Patients with chronic inflammatory diseases are at increased risk for heart failure due to ischemic heart disease and other causes including heart failure with preserved ejection fraction. Using rheumatoid arthritis and treated HIV infection as two prototypical examples, we review the epidemiology and potential therapies to prevent heart failure in these populations. Particular focus is given to anti-inflammatory therapies including statins and biologic disease modifying drugs. There is also limited evidence for lifestyle changes and blockade of the renin-angiotensin-aldosterone system. We conclude by proposing how a strategy for heart failure prevention, such as the model tested in the Screening To Prevent Heart Failure (STOP-HF) trial, may be adapted to chronic inflammatory disease.
