Cilostazol in patients with heart failure and preserved ejection fraction-The CLIP-HFpEF trial.

Background And Aims: Patients with heart failure with preserved ejection fraction (HFpEF) tend to have low resting and exercise heart rates. Phosphodiesterase-3 (PDE-3) inhibitors improve heart rates, haemodynamics and symptoms in patients with HFpEF. Cilostazol is an oral PDE-3 inhibitor used in peripheral artery disease.

Barriers and Facilitators to Accessing Opioid Agonist Therapy for Street-involved Adolescents and Young Adults in Vancouver.

Objective: Opioid agonist therapy (OAT) remains the first-line therapy for people with opioid use disorder. Whereas overdose rates among adolescents and young adults (AYAs) remain high, little is known about their access to OAT. Therefore, we sought to evaluate factors that shape access to OAT among AYAs aged 14 to 26 years.

Detection of Coronary Artery Disease With Coronary Computed Tomography Angiography and Stress Testing in Candidates for Liver Transplant.

Cardiac complications are the leading cause of morbidity and mortality in recipients of liver transplant (LT). Previous guidelines recommended stress testing to exclude coronary artery disease (CAD), although recent guidelines recommend coronary computed tomography angiography (CCTA). We aimed to assess the prevalence and predictors of CAD on CCTA and compare CCTA with stress testing in consecutive adult candidates for LT who underwent CAD noninvasive assessment between 2020 and 2023.

Heart Rate Lowering for Coronary CTA with Ivabradine in End-Stage Liver Disease.

In a study of 282 patients with end-stage liver disease undergoing coronary CT angiography, administration of a single dose of ivabradine (up to 15 mg) was found to be safe and effective at heart rate lowering.

Ventricular septal defect following mitral valve replacement.

Mitral valve surgery (MVS), with repair preferred to replacement, is a common procedure for the treatment of severe primary mitral regurgitation related to leaflet prolapse. Structural complications after MVS include left ventricular outflow obstruction, paravalvular leak and atrial septal defect. Intraoperative transoesophageal echocardiography and predischarge transthoracic echocardiography (TTE) specifically screen for these complications.

New-onset postoperative atrial fibrillation after mitral valve surgery: Determinants and the effect on survival.

Objective: Mitral valve surgery (MVS) carries substantial risk of postoperative atrial fibrillation (PAF). Identifying patients who benefit from prophylactic left atrial appendage amputation (LAAA) or maze is ill-defined. To guide such interventions, we determined preoperative predictors of PAF and investigated 3-year survival of patients with PAF.

Clinical characteristics and prognosis of patients with hypertrophic cardiomyopathy and heart failure with preserved ejection fraction.

Background: Whether heart failure with preserved ejection fraction (HFpEF) is associated with an increased risk of developing systolic dysfunction and a poor prognosis in hypertrophic cardiomyopathy (HCM) patients is unknown.

Objective: We aimed to assess risk factors for the development of end-stage (ES) heart failure (HF) (ejection fraction < 50%) and compare the prognosis of different HF phenotypes.

Methods: This retrospective study was conducted on patients with HCM in China between January 2009 and February 2023.

Impact of lung transplantation on diastolic dysfunction in recipients with pretransplant pulmonary hypertension.

Objective: Pulmonary hypertension can cause left ventricular diastolic dysfunction through ventricular interdependence. Moreover, diastolic dysfunction has been linked to adverse outcomes after lung transplant. The impact of lung transplant on diastolic dysfunction in recipients with pretransplant pulmonary hypertension is not defined.

Performance of Computed Tomographic Angiography-Based Aortic Valve Area for Assessment of Aortic Stenosis.

Background A total of 40% of patients with severe aortic stenosis (AS) have low-gradient AS, raising uncertainty about AS severity. Aortic valve calcification, measured by computed tomography (CT), is guideline-endorsed to aid in such cases. The performance of different CT-derived aortic valve areas (AVAs) is less well studied.

Integrated smoking cessation and mood management following acute coronary syndrome: Protocol for the post-acute cardiac event smoking (PACES) trial.

Background: Approximately 400,000 people who smoke cigarettes survive Acute Coronary Syndrome (ACS; unstable angina, ST and non-ST elevation myocardial infarction) each year in the US. Continued smoking following ACS is an independent predictor of mortality. Depressed mood post-ACS is also predictive of mortality, and smokers with depressed mood are less likely to abstain from smoking following an ACS.

Clinical Outcome After Left Ventricular Thrombus Resolution: Who Needs Long-Term or Lifetime Use of Anticoagulants?

Background Patients with left ventricular thrombus (LVT) resolution can have LVT recurrence and risk for thromboembolism. However, these outcomes after LVT resolution are not well known. We aimed to assess the prevalence, risk factors, and clinical outcomes for LVT recurrence in patients with LVT resolution to inform follow-up and treatment.

Incidental coronary calcium in cancer patients treated with anthracycline and/or trastuzumab.

Aims: Cancer patients are at increased risk of cardiovascular disease (CVD) after treatment with potentially cardiotoxic treatments. Many cancer patients undergo non-gated chest computed tomography (NCCT) for cancer staging prior to treatment. We aimed to assess whether coronary artery calcification on NCCT predicts CVD risk in cancer patients.

Impact of pectoralis muscle loss on cardiac outcome and survival in Cancer patients who received anthracycline based chemotherapy: retrospective study.

Introduction: The impact of pectoralis muscle mass index (PMI) on cardiac events is not well studied in cancer patients, especially in those who have received chemotherapy with high potential cardiac toxicity such as anthracyclines.

Methods: Individuals aged ≥18 years with a diagnosis of breast cancer, sarcoma, or lymphoma who received anthracycline-based chemotherapy at the University of Minnesota MHealth Fairview between 2009 and 2014. Eligible patients had to have two CT scans: a baseline CT scan within 6 months prior to chemotherapy and a follow-up CT scan within 2 years after treatment.

A rare case report of severe cardiomyopathy associated with myotonic dystrophy type 2.

Background: Myotonic dystrophies (DM) are multi-systemic diseases characterized by muscle weakness and myotonia. Despite a growing appreciation for the cardiovascular manifestations in myotonic dystrophy type 1 (DM1), cardiac involvement in myotonic dystrophy type 2 (DM2) has been less well characterized. In patients with DM2, cardiomyopathy has rarely been described.

Interplay of CT Coronary Plaque Characteristics and Ischemia to Predict Adverse Outcomes.

In 134 patients with stable coronary artery disease, high-risk plaque features at CT and physiologic stenosis were found to act in a synergistic fashion to predict adverse outcomes.

Prognostic impact of identifying etiology of prosthetic valve dysfunction with CT.

Background: In patients with prosthetic heart valves (PHV), there are distinct treatment implications based on prosthetic valve dysfunction (PVD) etiology. We investigated whether evaluation for PVD etiology on computed tomography (CT) has prognostic value for adverse clinical outcomes.

Methods: Consecutive patients with suspected PVD that had a clinically indicated contrast chest CT and echocardiogram done within 1 year of each other were identified retrospectively from the Prosthetic Heart Valve CT Registry at the University of Minnesota.

Sex Differences in Patients With Suspected Cardiac Sarcoidosis Assessed by Cardiovascular Magnetic Resonance Imaging.

Background: There are few data on sex differences in suspected cardiac sarcoidosis. Methods: Consecutive patients with histologically proven sarcoidosis and suspected cardiac involvement were studied. We investigated sex differences in presenting features, cardiac involvement, and the long-term incidence of a primary composite end point of all-cause death or significant ventricular arrhythmia and secondary end points of all-cause death and significant ventricular arrhythmia.

Variable and Severe Phenotypic Expression of the "Lebanese Allele" in Two Sisters with Familial Hypercholesterolemia.

The "Lebanese allele" { c.2043 C>A (p.cys681X)} is a nonsense mutation in the low-density lipoprotein receptor () gene that results in a truncated non-functioning LDLR protein.

Long-term prognostic value of right ventricular dysfunction on cardiovascular magnetic resonance imaging in anthracycline-treated cancer survivors.

Aims: We aimed to determine the prevalence of right ventricular (RV) systolic dysfunction on cardiovascular magnetic resonance imaging (CMR) and its impact on long-term adverse outcomes in a large cohort of cancer survivors treated with anthracycline-based chemotherapy.

Methods And Results: Consecutive cancer survivors treated with anthracyclines who underwent clinical CMR for suspected anthracycline-related cardiomyopathy were studied. The primary endpoint was a composite of all-cause death or major adverse cardiac events (MACE): heart failure hospitalization, heart transplantation, ventricular assist device implantation, resuscitated cardiac arrest, or life-threatening ventricular arrhythmia.

Prognostic Role of Paravalvular Spread on Computed Tomography in Suspected Prosthetic Valve Endocarditis.

We aimed to assess the prognostic value of computed tomography assessment of paravalvular spread in suspected prosthetic valve endocarditis.

Impact of 2016 SCCT/STR guidelines for coronary artery calcium scoring of noncardiac chest CT scans on lung cancer screening CT reporting.

The 2016 SCCT/STR guideline for coronary artery calcification (CAC) scoring on non-cardiac chest CT (NCCT) scans explicitly calls for the reporting of CAC. Whether the publication of the 2016 SCCT/STR guideline has had any impact on CAC reporting in lung cancer screening (LCS) scans has not been investigated. Consecutive patients with a LCS scan were identified from the University of Minnesota LCS registry and evaluated for CAC reporting in 3 separate cohorts: 6 months before, 6 months after, and 1 year after the publication of the 2016 SCCT/STR guideline.

Experimental and theoretical study of energy transfer in a chromophore triad: What makes modeling dynamics successful?

Simulation of electronic dynamics in realistically large molecular systems is a demanding task that has not yet achieved the same level of quantitative prediction already realized for its static counterpart. This is particularly true for processes occurring beyond the Born-Oppenheimer regime. Non-adiabatic molecular dynamics (NAMD) simulations suffer from two convoluted sources of error: numerical algorithms for dynamics and electronic structure calculations.
