A Critical Review of Icosapent Ethyl in Cardiovascular Risk Reduction.

Icosapent ethyl (IPE) was the first fish oil product the US Food and Drug Administration (FDA) approved to reduce the risk of atherosclerotic cardiovascular disease (ASCVD) in adults. IPE is an esterified version of eicosapentaenoic acid (EPA) and acts as a prodrug in the body to exert its effects. IPE affects the body primarily through triglyceride (TG) reduction and was initially indicated for hypertriglyceridemia in addition to statin therapy or for patients with statin intolerances. Various studies have investigated this agent, and multiple subanalyses have been conducted since the FDA approval. These subanalyses have assessed factors such as sex, statin therapy, high-sensitivity C-reactive protein levels (hs-CRP), and various inflammatory biomarkers in groups of patients taking IPE. This article aims to provide a critical review of the clinical data available regarding cardiovascular benefits of IPE in patients with ASCVD and its value as a treatment option for patients with elevated TG levels.

A Review of the Clinical Pharmacology of Pelacarsen: A Lipoprotein(a)-Lowering Agent.

Patients with genetically associated elevated lipoprotein(a) [Lp(a)] levels are at greater risk for coronary artery disease, heart attack, stroke, and peripheral arterial disease. To date, there are no US FDA-approved drug therapies that are designed to target Lp(a) with the goal of lowering the Lp(a) level in patients who have increased risk. The American College of Cardiology (ACC) has provided guidelines on how to use traditional lipid profiles to assess the risk of atherosclerotic cardiovascular disease (ASCVD); however, even with the emergence of statin add-on therapies such as ezetimibe and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, some populations with elevated Lp(a) biomarkers remain at an increased risk for cardiovascular (CV) disease. Residual CV risk has led researchers to inquire about how lowering Lp(a) can be used as a potential preventative therapy in reducing CV events. This review aims to present and discuss the current clinical and scientific evidence pertaining to pelacarsen.

Stenting and angioplasty with protection in patients at high-risk for endarterectomy: SAPPHIRE Worldwide Registry first 2,001 patients.

BACKGROUND: Previously, the Stenting and Angioplasty with Protection of Patients with High Risk for Endarterectomy (SAPPHIRE) randomized trial showed that carotid artery stenting (CAS) was not inferior to carotid endarterectomy (CEA) in the treatment of high-surgical risk patients. OBJECTIVE: The primary objective of the SAPPHIRE Worldwide Registry is to evaluate 30-day major adverse events (MAE) after CAS performed by physicians with varied experience and utilizing a formal training program. Data will be analyzed on the overall patient population and by high-risk inclusion criteria. METHODS: SAPPHIRE Worldwide is a multicenter, prospective, postapproval registry to evaluate CAS with distal protection in patients at high-risk for surgery using the Cordis PRECISE Nitinol Stent and ANGIOGUARD XP/RX Emboli Capture Guidewire. Participating physicians are encouraged to treat patients according to their standard of practice and consistent with current Food and Drug Administration-approved labeling. RESULTS: Enrollment began in October 2006. Data are available on the first 2,001 patients enrolled and followed to 30 days. Of these patients, the mean age was 72.2 +/- 9.75 yr; 62% were male; and 27.7% were symptomatic. Entry criteria for surgical high-risk included anatomic (n = 716), physiologic (n = 918), or both risk factors (n = 327). At 30-day follow-up, the MAE was 4.4% (death 1.1%, stroke 3.2%, MI 0.7%) for the overall population. Patients with anatomic risk had a significantly lower 30-day MAE than patients with physiologic risk (2.8% vs. 4.9%, P = 0.0306), respectively. CONCLUSIONS: While the number of physicians performing CAS continues to increase, MAE rates seen in this registry (4.4%) are well within an acceptable range, as was first seen in the SAPPHIRE randomized trial (4.8%). A significant decrease in MAE was seen in patients with anatomic risk compared with physiologic risk factors. The SAPPHIRE Worldwide Registry supports the use of CAS as an alternative to CEA in patients who are at high-risk for surgery due to anatomic risk factors.
