Development of and recovery from acute kidney injury after cardiac surgery: Randomized phase 2 trial of the hepatocyte growth factor mimetic ANG-3777.

Objectives: To investigate the safety and efficacy of ANG-3777, a hepatocyte growth factor mimetic, in mitigating the risk of acute kidney injury (AKI) in patients undergoing cardiac surgery with cardiopulmonary bypass.

Methods: In this double-blind placebo-controlled study (GUARD), patients were randomized to receive intravenous ANG-3777 2 mg/kg or placebo once daily for 4 days. The primary endpoint was AKI severity, measured by mean area under the concentration-time curve on percent increase in serum creatinine from days 2 to 6.

Syncope as the Sole Presentation of Multi-Vessel Coronary Artery Disease.

Defining the etiology of syncope can be occasionally challenging. We present a case with no history of coronary artery disease (CAD) who presented exclusively with exertional syncope, and was found to have mildly reduced left ventricular systolic dysfunction on echocardiogram and severe multi-vessel CAD with chronic total occlusion (CTO) of the right coronary artery (RCA). Syncope as the initial presentation of advanced CAD in the absence of classic ischemic symptoms is rather an uncommon presentation in clinical practice.

Long-term Outcomes of Acute Myocardial Infarction in Pre-existing Coronary Artery Ectasia: A Systematic Review and Meta-Analysis.

Coronary artery ectasia is associated with an increased risk of acute myocardial infarction. This meta-analysis evaluates outcomes following acute myocardial infarction in patients with pre-existing coronary artery ectasia. A search strategy was designed to utilize PubMed/Medline, EMBASE, and Google scholar for studies including the outcomes of acute myocardial infarction in patients with coronary artery ectasia from inception to February 10, 2022.

Prevalence and Outcomes in STEMI Patients Without Standard Modifiable Cardiovascular Risk Factors: A National Inpatient Sample Analysis.

To evaluate the in-hospital mortality and acute STEMI-related complications in a SMuRF-less STEMI population compared with a SMuRF STEMI population in the United States. The National Inpatient Sample (NIS) Database (2005-2014) was analyzed to identify patients with STEMI using ICD-9. Patients were grouped into SMuRF and SMuRF-less based on the presence of ≥1 SMuRF risk factor.

Teprasiran, a Small Interfering RNA, for the Prevention of Acute Kidney Injury in High-Risk Patients Undergoing Cardiac Surgery: A Randomized Clinical Study.

Background: Acute kidney injury (AKI) affects up to 30% of patients undergoing cardiac surgery, leading to increased in-hospital and long-term morbidity and mortality. Teprasiran is a novel small interfering RNA that temporarily inhibits p53-mediated cell death that underlies AKI.

Methods: This prospective, multicenter, double-blind, randomized, controlled phase 2 trial evaluated the efficacy and safety of a single 10 mg/kg dose of teprasiran versus placebo (1:1), in reducing the incidence, severity, and duration of AKI after cardiac surgery in high-risk patients.

Stroke and outcomes in patients with acute type A aortic dissection.

Background: Stroke is a highly dreaded complication of type A acute aortic dissection (TAAAD). However, little data exist on its incidence and association with prognosis.

Methods And Results: We evaluated 2202 patients with TAAAD (mean age 62 ± 14 years, 1487 [67.

Treatment and outcomes of first troponin-negative non-ST-segment elevation myocardial infarction.

Little is known about non-ST-segment elevation myocardial infarction (MI) in patients with an initial negative troponin finding. The aim of this study was to determine in post hoc analysis of a large regional medical center presenting clinical characteristics, treatment differences, and in-hospital and 6-month outcomes of first troponin-negative MI (FTNMI). In this study, 659 of 1,855 consecutive patients with non-ST-segment elevation MI (35.

Relation of kidney function and albuminuria with atrial fibrillation (from the Heart and Soul Study).

Atrial fibrillation (AF) is common in end-stage renal disease, but the relation between more modest decrements in kidney function or albuminuria with AF is uncertain. Among 956 outpatients with coronary artery disease, kidney function was assessed using 3 methods (cystatin C-based estimated glomerular filtration rate [eGFR(cys)], creatinine-based eGFR [eGFR(Cr)], and the urinary albumin/creatinine ratio [ACR]) and prevalent AF using surface electrocardiography. Multivariate logistic regression was used to evaluated the association of each measure of kidney function with AF.

N-terminal pro-B-type natriuretic peptide as a diagnostic test for ventricular dysfunction in patients with coronary disease: data from the heart and soul study.

Background: N-terminal pro-B-type natriuretic peptide (NT-proBNP) testing is useful for diagnosing acute decompensated heart failure. Whether NT-proBNP can be used to detect ventricular dysfunction in patients with stable coronary heart disease (CHD) and no history of heart failure is unknown.

Methods: We measured NT-proBNP levels and performed transthoracic echocardiography in 815 participants from the Heart and Soul Study, who had stable CHD and no history of heart failure.
