Einstein Health Papers

AIMS: Structural heart disease is often underdiagnosed, and echocardiography is limited by access and referral thresholds. Artificial intelligence electrocardiography (AI-ECG) may identify echocardiographically defined structural heart disease. EchoNext-Mini is a released AI-ECG model, accompanied by a benchmark dataset, that detects a composite structural heart disease outcome and component conditions from 12-lead electrocardiogram waveforms together with age, sex, and electrocardiographic measurements. We assessed its transportability and recalibration.

METHODS AND RESULTS: We linked electrocardiograms from MIMIC-IV to subsequent transthoracic echocardiograms, including adults whose electrocardiogram preceded an eligible echocardiogram within one year, one per patient. Labels were mapped to structured echocardiographic fields using …

Pharmacogenetics In Pediatric Cardiology., Adenike Adenikinju, Jonathan B. Wagner, Mollie Walton

Manuscripts, Articles, Book Chapters and Other Papers

Children with congenital and acquired heart disease frequently require complex and prolonged pharmacotherapy, often involving off-label cardiovascular medications with narrow therapeutic ranges. Consequently, variability in drug response and medication-related adverse events remains a significant clinical challenge in pediatric cardiology. Pharmacogenetics provides a framework to individualize drug selection and dosing by incorporating genetic variability alongside established clinical and developmental factors. This review outlines the current clinical utility and emerging role of pharmacogenetics in pediatric cardiology, emphasizing applications most relevant to day-to-day patient care. Established pharmacogenetic associations with direct implications for pediatric cardiac practice include gene-drug pairs involving tacrolimus (CYP3A5), …

Traumatic brain injury (TBI) is associated with cardiovascular dysfunction that worsens clinical outcomes, yet the underlying mechanisms are poorly under stood. Clinical studies are limited by heterogeneity, highlighting the need for con trolled experimental models. Controlled cortical impact (CCI) provides precise control of injury severity, and invasive pressure- volume (PV) loop analysis allows detailed hemodynamic assessment. Adult male Wistar rats underwent sham op eration or mild or severe CCI- induced TBI. PV- loop assessment and transtho racic echocardiography were performed at 8 or 24 h after TBI or sham. Serum epinephrine (EPI) and norepinephrine (NE) were quantified by ELISA. At …

A Case Report Of Myocardial Infarction Complicated With Blood Pressure Fluctuations Caused By Pheochromocytoma, Huiping Li, Wei Yang, Yu Feng, You Zhang, Gan-Xin Yan, Chuanyu Gao

Department of Medicine Faculty Papers

Pheochromocytoma typically presents with sustained or paroxysmal hypertension, but initial manifestation as acute non-ST-segment elevation myocardial infarction (NSTEMI) is rare. Peri-procedural hemodynamic fluctuations are often dramatic, making diagnosis and management challenging. We report a 51-year-old male admitted with chest tightness for 17 days. Elevated troponin and coronary angiography showing multivessel disease with total occlusion of the mid-left anterior descending artery (LAD) led to a preliminary diagnosis of NSTEMI. During percutaneous coronary intervention, blood pressure surged to 240/130 mmHg; intravenous nitroprusside caused an instantaneous drop to 95/55 mmHg, with rapid rebound to >200 mmHg upon withdrawal, showing no clear temporal relationship …

Recalibrating Risk: A Call For South Asian-Focused Heart Failure Prediction Models, Nandini Nair, Dongping Du, Aiswarya J. Pillai, Swarna Mahesh, Mrudula R. Munagala, Howard J. Eisen, Balakrishnan Mahesh

Division of Cardiology Faculty Papers

Background: Heart failure (HF) represents the final common pathway of diverse cardiovascular disorders, including coronary artery disease, primary myocardial pathology, and abnormalities of cardiac conduction. These conditions arise from an interplay of genetic, environmental, and psychosocial influences, making it essential to understand these determinants to improve risk prediction and prevention. Multiple biological pathways of inflammation, fibrosis, coagulation, oxidative stress, lipid dysregulation, endothelial dysfunction, and metabolic disturbances are shaped by inherited susceptibility and modifiable exposures. Together, these mechanisms drive HF development and progression, though their relative contributions vary across populations. Methods: PubMed and Google Scholar were searched for clinical, biomedical, and …

Risk factors (RF) for permanent pacemaker (PPM) placement in cardiac surgery include valvular operations and redo operations. We aim to identify RF for PPM placement prior to discharge (DC) specifically among redo mitral valvular operations, and to analyze outcomes in this population. Our retrospective review considered 943 patients undergoing redo MV operations between 01/2002 and 12/2021, excluding patients experiencing in-hospital death within 48 hours of their operation and patients with existing PPM or implanted cardiac defibrillator (ICD). Patients (n = 742) were categorized based on whether they received a PPM before DC or not. Of the 742 patients analyzed, 47 …

In Vivo Evidence Of Blood Flow Slippage: Failure Of The No-Slip Boundary Condition Assumption, Alena Jarolímová, Jaroslav Hron, Karel Tůma, Radomír Chabiniok, Josef Málek, Keshava Rajagopal

Division of Cardiology Faculty Papers

The assumption that blood adheres to vessel walls with zero tangential velocity component, the so-called "no-slip" boundary condition, is a foundational premise of cardiovascular fluid dynamics. Whether the no-slip condition holds in vivo, however, remains unknown. Seven healthy adult volunteers underwent cardiovascular magnetic resonance imaging. With four-dimensional flow magnetic resonance imaging of the descending thoracic aorta and modeling blood as a Navier-Stokes fluid, near-wall blood velocities were quantified, and wall shear stress was calculated based on the measured velocity fields. Within the Navier-Stokes data assimilation framework, tangential wall velocities of ∼30-80% of the mean luminal velocity were consistently obtained. These …

Eraso, Paul J. Dimuzio, Dario Pitocco, Massimo Massetti, Antonio Gasbarrini, Andrea Flex

Department of Surgery Faculty Papers

BACKGROUND: Patients with type 2 diabetes mellitus (T2DM) and chronic limb-threatening ischemia (CLTI) undergoing lower extremity revascularization (LER) face high risks of major adverse cardiovascular events (MACE) and major adverse limb events (MALE), despite guideline-directed lipid-lowering therapy. Apolipoprotein B100 (ApoB100), reflecting total atherogenic particle number, may identify residual risk beyond LDL-cholesterol (LDL-C). Therefore, we investigated whether baseline ApoB100 levels independently predict MACE and MALE beyond conventional risk factors in this high-risk population.

METHODS: In this prospective cohort study, 167 T2DM patients with CLTI undergoing LER were followed for 12 months with visits at 1, 3, 6, and 12 months post-procedure. …

Internal Medicine, East Africa

Introduction: hypertension represents the primary modifiable risk factor for cardiovascular disease and poses a public health challenge in sub-Saharan regions, with Kenya experiencing particularly low detection and control rates. Traditional office-based blood pressure measurements often fail to detect key phenotypes, such as white-coat and masked hypertension. Ambulatory Blood Pressure Monitoring (ABPM) offers a comprehensive 24-hour profile that excludes white-coat hypertension and allows for the evaluation of circadian patterns, including nocturnal hypertension and non-dipping status, both of which are recognized as high-risk phenotypes strongly linked to adverse cardiovascular events. This study evaluated ABPM data from Aga Khan University Hospital, Nairobi …
