Accurately predicting patients' risk for specific medical outcomes is paramount for effective healthcare management and personalized medicine. While a substantial body of literature addresses the prediction of diverse medical conditions, existing models predominantly focus on singular outcomes, limiting their scope to one disease at a time. However, clinical reality often entails patients concurrently facing multiple health risks across various medical domains.

Urban environments contribute substantially to the rising burden of cardiometabolic diseases worldwide. Cities are complex adaptive systems that continually exchange resources, shaping exposures relevant to human health such as air pollution, noise, and chemical exposures. In addition, urban infrastructure and provisioning systems influence multiple domains of health risk, including behaviors, psychological stress, pollution, and nutrition through various pathways (eg, physical inactivity, air pollution, noise, heat stress, food systems, the availability of green space, and contaminant exposures).

Curr Cardiol Rep

June 2024

DeBakey Heart & Vascular Center, Houston Methodist Hospital, 6550 Fannin St, Smith Tower Suite 1901, Houston, TX, 77030, USA.

Purpose Of Review: The study of adults with congenital heart disease (ACHD) is a rapidly growing field; however, more research is needed on the disparities affecting outcomes. With advances in medicine, a high percentage of patients with congenital heart disease (CHD) are advancing to adulthood, leading to an increase in the number of ACHD. This creates a pressing need to evaluate the factors, specifically the social determinants of health (SDOH) contributing to the outcomes for ACHD.

Medicare beneficiaries' healthcare spending varies across geographical regions, influenced by availability of medical resources and institutional efficiency. We aimed to evaluate whether social vulnerability influences healthcare costs among Medicare beneficiaries. Multivariable regression analyses were conducted to determine whether the social vulnerability index (SVI), released by the Centers for Disease Control and Prevention (CDC), was associated with average submitted covered charges, total payment amounts, or total covered days upon hospital discharge among Medicare beneficiaries.

Convolutional Neural Networks to Study Contrast-Enhanced Magnetic Resonance Imaging-Based Skeletal Calf Muscle Perfusion in Peripheral Artery Disease.

Am J Cardiol

June 2024

Penn State Heart and Vascular Institute, Pennsylvania State University College of Medicine, Hershey, Pennsylvania; Section of Cardiovascular Research, Department of Medicine, Baylor College of Medicine, Houston, Texas. Electronic address:

Peripheral artery disease (PAD) is associated with impaired blood flow in the lower extremities and histopathologic changes of the skeletal calf muscles, resulting in abnormal microvascular perfusion. We studied the use of convolution neural networks (CNNs) to differentiate patients with PAD from matched controls using perfusion pattern features from contrast-enhanced magnetic resonance imaging (CE-MRI) of the skeletal calf muscles. We acquired CE-MRI based skeletal calf muscle perfusion in 56 patients (36 patients with PAD and 20 matched controls).

Article Synopsis
  • The study compares the 5-year rates of valve reintervention after transcatheter aortic valve replacement (TAVR) using CoreValve/Evolut versus surgical aortic valve replacement (SAVR).
  • It found that TAVR had a higher overall reintervention rate (2.2%) compared to SAVR (1.5%), particularly within the first year.
  • Evolut TAVR showed significantly fewer reinterventions than CoreValve TAVR, but its rates were comparable to SAVR, indicating varying risks associated with different valve types.

Structural heart disease interventions rely heavily on preprocedural planning and simulation to improve procedural outcomes and predict and prevent potential procedural complications. Modeling technologies, namely 3-dimensional (3D) printing and computational modeling, are nowadays increasingly used to predict the interaction between cardiac anatomy and implantable devices. Such models play a role in patient education, operator training, procedural simulation, and appropriate device selection.

Spectrum of Ischemic Heart Disease Throughout a Woman's Life Cycle.

Methodist Debakey Cardiovasc J

March 2024

Methodist DeBakey Cardiology Associates.

Ischemic heart disease (IHD) is the leading cause of morbidity and mortality in both genders; however, young women fare the worst, likely reflecting the more complex spectrum of IHD in women when compared to men. Substantial sex-based differences exist in the underlying risk factors, risk enhancers, presentation, diagnosis, and pathophysiology of IHD that are mainly attributed to the influence of female sex hormones. This article reviews the spectrum of IHD including obstructive epicardial coronary artery disease (CAD), myocardial infarction with no obstructive coronary artery disease, ischemia with no obstructive coronary artery disease, spontaneous coronary artery dissection, coronary microvascular dysfunction, vasospastic angina, and coronary thrombosis/embolism that occur in women throughout various stages of their life cycle.
