Objectives: The purpose of this study was to examine the association of increased telemedicine use on rates of timely follow-up and unplanned readmission after acute cardiovascular hospital encounters.

Methods: We examined hospital encounters for acute coronary syndrome, arrhythmia disorders, heart failure (HF), and valvular heart disease from a large U.

Association of Myocardial Blood Flow Reserve With Adverse Left Ventricular Remodeling in Patients With Aortic Stenosis: The Microvascular Disease in Aortic Stenosis (MIDAS) Study.

Importance: Impaired myocardial flow reserve (MFR) and stress myocardial blood flow (MBF) on positron emission tomography (PET) myocardial perfusion imaging may identify adverse myocardial characteristics, including myocardial stress and injury in aortic stenosis (AS).

Objective: To investigate whether MFR and stress MBF are associated with LV structure and function derangements, and whether these parameters improve after aortic valve replacement (AVR).

Design, Setting, And Participants: In this single-center prospective observational study in Boston, Massachusetts, from 2018 to 2020, patients with predominantly moderate to severe AS underwent ammonia N13 PET myocardial perfusion imaging for myocardial blood flow (MBF) quantification, resting transthoracic echocardiography (TTE) for assessment of myocardial structure and function, and measurement of circulating biomarkers for myocardial injury and wall stress.

Virtual optimization of guideline-directed medical therapy in hospitalized patients with heart failure with reduced ejection fraction: the IMPLEMENT-HF pilot study.

Aims: Implementation of guideline-directed medical therapy (GDMT) for heart failure with reduced ejection fraction (HFrEF) remains incomplete. Non-cardiovascular hospitalization may present opportunities for GDMT optimization. We assessed the efficacy and durability of a virtual, multidisciplinary 'GDMT Team' on medical therapy prescription for HFrEF.

Accelerating massively parallel hemodynamic models of coarctation of the aorta using neural networks.

Comorbidities such as anemia or hypertension and physiological factors related to exertion can influence a patient's hemodynamics and increase the severity of many cardiovascular diseases. Observing and quantifying associations between these factors and hemodynamics can be difficult due to the multitude of co-existing conditions and blood flow parameters in real patient data. Machine learning-driven, physics-based simulations provide a means to understand how potentially correlated conditions may affect a particular patient.

Fewer Hospitalizations for Acute Cardiovascular Conditions During the COVID-19 Pandemic.

Background: Although patients with cardiovascular disease face excess risks of severe illness with coronavirus disease-2019 (COVID-19), there may be indirect consequences of the pandemic on this high-risk patient segment.

Objectives: This study sought to examine longitudinal trends in hospitalizations for acute cardiovascular conditions across a tertiary care health system.

Methods: Acute cardiovascular hospitalizations were tracked between January 1, 2019, and March 31, 2020.

Isolated surgical left atrial appendage closure: Revisiting utility and indications in a burgeoning era of percutaneous therapy.

Background And Aim: Oral anticoagulation (AC) and percutaneous left atrial appendage (LAA) occlusion are the primary treatment modalities for stroke prevention in atrial fibrillation (AF), but there remains a subset of patients in whom these approaches present excess risk and isolated surgical LAA excision should be considered. We describe a 63-year-old female with AF and recurrent thromboembolic events who presented with an acute intraparenchymal hemorrhage and was found to have an intracardiac thrombus.

Methods: Given contraindications to AC and LAA occlusion, an isolated LAA surgical excision was pursued.

Hypertensive coronary microvascular dysfunction: a subclinical marker of end organ damage and heart failure.

Aims: Hypertension is a well-established heart failure (HF) risk factor, especially in the context of adverse left ventricular (LV) remodelling. We aimed to use myocardial flow reserve (MFR) and global longitudinal strain (GLS), markers of subclinical microvascular and myocardial dysfunction, to refine hypertensive HF risk assessment.

Methods And Results: Consecutive patients undergoing symptom-prompted stress cardiac positron emission tomography (PET)-computed tomography and transthoracic echocardiogram within 90 days without reduced left ventricular ejection fraction (<40%) or flow-limiting coronary artery disease (summed stress score ≥ 3) were included.

Coronary microvascular dysfunction, left ventricular remodeling, and clinical outcomes in aortic stenosis.

Background: We investigated role of coronary microvascular disease (CMD) in maladaptive LV remodeling and prognosis in patients with aortic sclerosis or stenosis and no overt CAD.

Methods: This was a retrospective cohort study of patients with aortic sclerosis or stenosis, normal myocardial perfusion and LV ejection fraction (EF) > 50% (n = 43) and matched controls without AS (n = 43). PET and echocardiograms were performed within 1 year of each other.

A Comparison of Whole Genome Sequencing to Multigene Panel Testing in Hypertrophic Cardiomyopathy Patients.

Background: As DNA sequencing costs decline, genetic testing options have expanded. Whole exome sequencing and whole genome sequencing (WGS) are entering clinical use, posing questions about their incremental value compared with disease-specific multigene panels that have been the cornerstone of genetic testing.

Methods And Results: Forty-one patients with hypertrophic cardiomyopathy who had undergone targeted hypertrophic cardiomyopathy genetic testing (either multigene panel or familial variant test) were recruited into the MedSeq Project, a clinical trial of WGS.

Non-functional tricuspid valve disease.

Only 75% of severe tricuspid regurgitation is classified as functional, or related primarily to pulmonary hypertension, right ventricular dysfunction, or a combination of both. Non-functional tricuspid regurgitation occurs when there is damage to the tricuspid leaflets, chordae, papillary muscles, or annulus, independent of right ventricular dysfunction or pulmonary hypertension. The entities that cause non-functional tricuspid regurgitation include rheumatic and myxomatous disease, acquired and genetic connective tissue disorders, endocarditis, sarcoid, pacing, RV biopsy, blunt trauma, radiation, carcinoid, ergot alkaloids, dopamine agonists, fenfluramine, cardiac tumors, atrial fibrillation, and congenital malformations.

Objectives: The purpose of this study was to determine the extent to which effectiveness of cardiac and diabetes treatment strategies varies by patient age.

Background: The impact of age on the effectiveness of revascularization and hyperglycemia treatments has not been thoroughly investigated.

Methods: In the BARI 2D (Bypass Angioplasty Revascularization Investigation in Type 2 Diabetes) trial, 2,368 patients with documented stable heart disease and type 2 diabetes were randomized to receive prompt revascularization versus initial medical therapy with deferred revascularization and insulin sensitization versus insulin provision for hyperglycemia treatment.

Sex, clinical symptoms, and angiographic findings in patients with diabetes mellitus and coronary artery disease (from the Bypass Angioplasty Revascularization Investigation [BARI] 2 Diabetes trial).

Previous studies have reported differences in presenting symptoms and angiographic characteristics between women and men undergoing evaluation for suspected coronary artery disease (CAD). We examined the relation between symptoms and extent of CAD in patients with type 2 diabetes mellitus and known CAD enrolled in the Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial. Of 1,775 patients (533 women, 30%, and 1,242 men, 70%), women were more likely than men to have angina (65% vs 56%, p <0.

Safety and efficacy of bone marrow-derived autologous CD133+ stem cell therapy.

The Phase I clinical study was designed to assess the safety and feasibility of a dose escalating intracoronary infusion of autologous bone marrow (BM)-derived CD133+ stem cell therapy to the patients with chronic total occlusion (CTO) and ischemia. Nine patients were received CD133+ cells into epicardial vessels supplying collateral flow to areas of viable ischemic myocardium in the distribution of the CTO. There were no major adverse cardiac events (MACE), revascularization, re-admission to the hospital secondary to angina, or acute myocardial infarction (AMI) for the 24-month period following cellular infusion.

Background: The Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial in 2368 patients with stable ischemic heart disease assigned before randomization to percutaneous coronary intervention or coronary artery bypass grafting strata reported similar 5-year all-cause mortality rates with insulin sensitization versus insulin provision therapy and with a strategy of prompt initial coronary revascularization and intensive medical therapy or intensive medical therapy alone with revascularization reserved for clinical indication(s). In this report, we examine the predefined secondary end points of cardiac death and myocardial infarction (MI).

Methods And Results: Outcome data were analyzed by intention to treat; the Kaplan-Meier method was used to assess 5-year event rates.

Is chronic kidney disease comparable to diabetes as a coronary artery disease risk factor?

Background: Chronic kidney disease (CKD) is one of the known risk factors for coronary heart disease (CHD). Though electrocardiograms (ECGs) have limited accuracy in determining the true prevalence of CHD, we wondered whether CKD and diabetes mellitus (DM) controlled for hypertension (HTN), had similar prevalences of ECG abnormalities that could reflect underlying coronary heart disease.

Method: Data were collected for 5,942 men and women aged 30 to 69 years in the Tehran Lipid and Glucose Study (TLGS), a crosssectional phase of a large epidemiologic study first initiated in 1999.
