A substantial number of patients may experience a systemic inflammatory response syndrome (SIRS) and related adverse events after transcatheter aortic valve implantation and endovascular aortic aneurysm repair. Although a clear etiology has not been established, endothelial disruption and tissue-ischemic response secondary to the foreign material may represent the trigger events. A latency period (0-48 hours) may occur between the initial injury and onset of symptoms mirroring an initial local response followed by a systemic response...

Postoperative atrial fibrillation (POAF) is commonly seen in patients undergoing coronary artery bypass grafting (CABG), increasing the risk of morbidity, mortality and hospital expenses. This study is aimed to evaluate the effect of partial cardiac denervation, which is achieved by cutting off the ligament of Marshall and resecting the fat pad along the Waterston groove, on the prevention of POAF after CABG. Patients planned for CABG at our center will be screened for eligibility for this study. A total of 430 patients will be randomized into intervention (partial cardiac denervation) group and control group...

Recurrent ventricular tachycardia (VT) in patients with prior myocardial infarction is associated with adverse quality of life and clinical outcomes, despite the presence of implanted defibrillators (ICDs). Suppression of recurrent VT can be accomplished with antiarrhythmic drug therapy or catheter ablation. The Ventricular Tachycardia Antiarrhythmics or Ablation In Structural Heart Disease 2 (VANISH2) trial is designed to determine whether ablation is superior to antiarrhythmic drug therapy as first line therapy for patients with ischemic cardiomyopathy and VT...

Background: Recent clinical trials and guideline updates have highlighted the efficacy and safety of sodium-glucose cotransporter-2 inhibitor (SGLT2i) use in patients with type 2 diabetes (T2D) and comorbidities including atherosclerotic cardiovascular disease (ASCVD), chronic kidney disease (CKD), or heart failure (HF). Objective: This study assesses the rates of guideline-based prescribing of SGLT2i in patients with T2D and one or more of the following comorbidities: ASCVD, CKD, or HF, prior to and after the 2022 American Diabetes Association (ADA) guideline publication within the Atrius Health clinical pharmacy, internal medicine, and specialty medicine departments...

The strong association between lipoprotein (a) [Lp(a)] and atherosclerotic cardiovascular disease has led to considerations of Lp(a) being a potential target for mitigating residual cardiovascular risk. While approximately 20 % of the population has an Lp(a) level greater than 50 mg/dL, there are no currently available pharmacological lipid-lowering therapies that have demonstrated substantial reduction in Lp(a). Novel therapies to lower Lp(a) include antisense oligonucleotides and small-interfering ribonucleic acid molecules and have shown promising results in phase 2 trials...

High levels of lipoprotein(a) [Lp(a)] are causal for atherosclerotic cardiovascular disease (ASCVD). Lp(a) is the most prevalent inherited dyslipidemia and strongest genetic ASCVD risk factor. This risk persists in the presence of at target, guideline-recommended, LDL-C levels and adherence to lifestyle modifications. Epidemiological and genetic evidence supporting its causal role in ASCVD and calcific aortic stenosis continues to accumulate, although various facets regarding Lp(a) biology (genetics, pathophysiology, and expression across race/ethnic groups) are not yet fully understood...

OBJECTIVE: To evaluate whether and to what extent changes in cardiovascular health (CVH) based on life's essential 8 (LE8) are associated with incident cardiovascular disease (CVD). METHODS: A total of 7,194 participants were derived from UK Biobank. CVH was evaluated using a modified version of LE8. Participants were classified into three groups according to their LE8 score: high CVH (LE8 score≥80), moderate CVH (50≤LE8 score<80), and low CVH (LE8 score<50)...

Atrial fibrillation was largely ignored by cardiac electrophysiologists until it was first suggested in 1998 that it might be amenable to catheter ablation. In the 25 years since then, a vast literature has emerged, initially reporting the 'hypes and hopes' that ablation was appropriate for all, but more recently acknowledging that not all patients benefit from this approach. The atrial fibrillation 'epidemic' and more holistic understanding of the complex contributors to its development question whether, it is even meaningful, to consider atrial fibrillation a single condition that is always responsive to ablation management...

BACKGROUND: Right ventricular (RV) to pulmonary arterial (PA) coupling describes the ability of the RV to augment contractility in response to increased afterload. Several echocardiographic indexes of RV-PA coupling have been defined; however, the optimal numerator in the coupling ratio is unclear. We sought to establish which of these ratios is best for assessing RV-PA coupling based on their relationships with 6-minute walk distance (6MWD), N-terminal pro-B-type natriuretic peptide (NT-proBNP), and the Kansas City Cardiomyopathy Questionnaire (KCCQ) in aging adults...

Intracardiac echocardiography (ICE) has emerged as an alternative to transesophageal echo (TEE) to guide left atrial appendage occlusion (LAAO). We established a protocol to select patients appropriate for ICE guidance. Patients undergoing LAAO with the Watchman or Watchman FLX device (Boston Scientific, Marlborough, MA) from January 2018-March 2022 at a large United States center were included. The novel protocol prospectively selected TEE or ICE guidance beginning in January 2020; previous LAAO procedures were retrospectively included...

Sudden cardiac death (SCD) represents the most severe complication of hypertrophic cardiomyopathy (HCM). However, the relationship between strain, strain rate, and risk factors in SCD risk stratification remains elusive. The study aimed to assess the attenuation of strain and strain rate in HCM by feature-tracking cardiac magnetic resonance (FT-CMR). All strain and strain rates were obtained automatically by FT, with manual adjustment of endocardial and epicardial borders. Strain indicators included left ventricular (LV) global longitudinal (GLS), circumferential (GCS), radial strain (GRS), peak diastolic-longitudinal (PD-LSR), circumferential (PD-CSR), and radial strain rate (PD-RSR)...

Despite a 30% decline in the rate over the last decade, coronary artery bypass graft (CABG) surgery remains a common major surgical procedure with significant morbidity and mortality. Chronic liver disease (CLD) patients, with increased survival rates due to medical advancements, are now frequently being considered for CABG, bearing higher perioperative risks. This study investigates the association between CLD and in-hospital outcomes in CABG patients using retrospective data from the National Inpatient Sample (NIS) database (2016-2020) including 7,945 CLD patients undergoing CABG that were propensity score matched with an equivalent number of patients with no CLD undergoing CABG...

BACKGROUND: Risk of recurrence after minor ischemic stroke is usually reported with transient ischemic attack. No previous meta-analysis has focused on minor ischemic stroke alone. The objective was to evaluate the pooled proportion of 90-day stroke recurrence for minor ischemic stroke, defined as a National Institutes of Health Stroke Scale severity score of ≤5. METHODS AND RESULTS: Published papers found on PubMed from 2000 to January 12, 2021, reference lists of relevant articles, and experts in the field were involved in identifying relevant studies...

Placebo-controlled trials of sodium-glucose cotransporter-2 inhibitors (SGLT2i) demonstrate kidney and cardiovascular benefits for people with type 2 diabetes (T2D) and chronic kidney disease (CKD). We used real-world data to compare the kidney and cardiovascular effectiveness of empagliflozin to dipeptidyl peptidase-4 inhibitors (DPP4i), a commonly prescribed antiglycemic medication, in a diverse population with and without CKD. Using electronic health record data from 20 large US health systems, we leveraged propensity overlap weighting to compare outcomes for empagliflozin and DPP4i initiators with T2D between 2016 and 2020...

The number of different methodologies of reperfusion therapy to treat venous thromboembolism (VTE) has increased substantially. Nevertheless, investigation of data representativeness and device-level usage in administrative databases has been limited. Using the National Inpatient Sample (NIS) and the PINC AI Healthcare Database (PHD), all hospital encounters with a diagnosis code of VTE were identified between 1/1/2016 and 12/31/2020. Patient demographics and trends in treatment modalities were evaluated over time...
