Rate-dependent effects of lidocaine on cardiac dynamics: Development and analysis of a low-dimensional drug-channel interaction model [PDF]

open access: yes, 2021
State-dependent Na+ channel blockers are often prescribed to treat cardiac arrhythmias, but many Na+ channel blockers are known to have pro-arrhythmic side effects. While the anti and proarrhythmic potential of a Na+ channel blocker is thought to depend on the characteristics of its rate-dependent block, the mechanisms linking these two attributes are ...

Distinct load dependence of relaxation rate and diastolic function in Oryctolagus cuniculus and Ratus norvegicus [PDF]

open access: yes, 2003
This study investigated potential differences on load dependence of relaxation rate and diastolic function between Oryctolagus cuniculus and Ratus norvegicus, which have constitutive differences in the mechanisms involved in myocardial inactivation. Load

Elastic recoil signal on tissue doppler imaging of mitral annulus as a qualitative test to identify left ventricular diastolic function

open access: yesAnnals of Cardiac Anaesthesia, 2023
Introduction: Left ventricular (LV) diastolic dysfunction is common on preoperative screening among patients undergoing surgery. There is no simple screening test at present to suspect LV diastolic dysfunction. This study was aimed to test the hypothesis,

Quantile regression for mixed models with an application to examine blood pressure trends in China [PDF]

open access: yesAnnals of Applied Statistics 2015, Vol. 9, No. 3, 1226-1246, 2015
Cardiometabolic diseases have substantially increased in China in the past 20 years and blood pressure is a primary modifiable risk factor. Using data from the China Health and Nutrition Survey, we examine blood pressure trends in China from 1991 to 2009, with a concentration on age cohorts and urbanicity.

Modern Multiple Imputation with Functional Data [PDF]

open access: yesStat, 2021, 2020
This work considers the problem of fitting functional models with sparsely and irregularly sampled functional data. It overcomes the limitations of the state-of-the-art methods, which face major challenges in the fitting of more complex non-linear models.

Hyperglycemia Has a Greater Impact on Left Ventricle Function in South Asians Than in Europeans [PDF]

open access: yes, 2013
OBJECTIVE Diabetes is associated with left ventricular (LV) diastolic and systolic dysfunction. South Asians may be at particular risk of developing LV dysfunction owing to a high prevalence of diabetes.

Improvement of diastolic dysfunction after percutaneous coronary intervention in patients with ischemic cardiomyopathy

open access: yesJournal of Medicine in Scientific Research, 2018
Introduction Impaired systolic cardiac function in patients with ischemic cardiac disease is well known. Diastolic cardiac dysfunction is also found in these patients, so we aimed to show whether percutaneous coronary intervention (PCI) could improve ...
