Parameter inference in a computational model of hemodynamics in pulmonary hypertension [PDF]
arXiv, 2021 Pulmonary hypertension (PH), defined by a mean pulmonary arterial pressure (mPAP) $>$ 20 mmHg, is characterized by increased pulmonary vascular resistance and decreased pulmonary arterial compliance. There are few measurable biomarkers of PH progression, but a conclusive diagnosis of the disease requires invasive right heart catheterization (RHC ...

Murottal and Clasical Music Therapy Reducing Pra Cardiac Chateterization Anxiety
South East Asia Nursing Research, 2019 The high incidence of patients with coronary heart disease is directly proportional to the increase in cardiac catheterization. Many patients who experience anxiety pre heart catheterization will need nursing action.

Anesthetic management of neonates undergoing diagnostic and therapeutic cardiac catheterization: a systematic literature review [PDF]
Revista Brasileira de AnestesiologiaBackground: Several interventional cardiology procedures are required in neonates with congenital heart disease. Interventional cardiology procedures have a higher risk of cardiac arrest compared to other interventions.

Testing Biased Randomization Assumptions and Quantifying Imperfect Matching and Residual Confounding in Matched Observational Studies [PDF]
arXiv, 2021 One central goal of design of observational studies is to embed non-experimental data into an approximate randomized controlled trial using statistical matching. Despite empirical researchers' best intention and effort to create high-quality matched samples, residual imbalance due to observed covariates not being well matched often persists.

Frontiers in Cardiovascular MedicineBackgroundWhile several studies have explored the outcomes of transcatheter interventions for modified Blalock–Taussig shunts (MBTSs) in a broad range of congenital heart diseases, none have specifically examined the interventions in patients with ...

Variable Selection for Causal Inference via Outcome-Adaptive Random Forest [PDF]
arXiv, 2021 Estimating a causal effect from observational data can be biased if we do not control for self-selection. This selection is based on confounding variables that affect the treatment assignment and the outcome. Propensity score methods aim to correct for confounding. However, not all covariates are confounders.

Covariate-adaptive randomization inference in matched designs [PDF]
arXiv, 2022 It is common to conduct causal inference in matched observational studies by proceeding as though treatment assignments within matched sets are assigned uniformly at random and using this distribution as the basis for inference. This approach ignores observed discrepancies in matched sets that may be consequential for the distribution of treatment ...
