Artificial Intelligence in Cardiology—A Narrative Review of Current Status
(2022)Artificial intelligence (AI) is an integral part of clinical decision support systems (CDSS), offering methods to approximate human reasoning and computationally infer decisions. Such methods are generally based on medical ... -
Continuous chest compressions with asynchronous ventilation improve survival in a neonatal swine model of asphyxial cardiac arrest
(2021)Background: Guidelines for neonatal resuscitation recommend a 3:1 compression to ventilation ratio. However, this recommendation is based on expert opinion and consensus rather than strong scientific evidence. Our primary ... -
Determinants of venous return in steady-state physiology and asphyxia-induced circulatory shock and arrest: an experimental study
(2022)Background: Mean circulatory filling pressure (Pmcf) provides information on stressed volume and is crucial for maintaining venous return. This study investigated the Pmcf and other determinants of venous return in dysrhythmic ... -
Diagnosis and management of chronic coronary artery disease
(2007)Coronary artery disease (CAD) usually coexists with atherosclerosis of other arterial trees and is accelerated by several risk factors. It may remain asymptomatic for a long period affecting the vessel wall with no lumen ... -
Diastolic Doppler flow and tissue Doppler velocities during, and in recovery from, low-intensity supine exercise
(2008)Recent studies have reported evidence of both a short-term and a more sustained reduction in left ventricular diastolic function after prolonged strenuous exercise. Interpretation of this data is confounded by alterations ... -
EANM procedural guidelines for PET/CT quantitative myocardial perfusion imaging
(2021)The use of cardiac PET, and in particular of quantitative myocardial perfusion PET, has been growing during the last years, because scanners are becoming widely available and because several studies have convincingly ... -
Effects of anti-inflammatory treatment and surgical intervention on endothelial glycocalyx, peripheral and coronary microcirculatory function and myocardial deformation in inflammatory bowel disease patients: A two-arms two-stage clinical trial
(2021)Sixty inflammatory bowel disease (IBD) patients (45 Crohn disease and 15 ulcerative colitis, 40 ± 13 years, 53% male) were examined at baseline and 4 months after intervention (surgical (35 patients) or anti-TNFa treatment ... -
Impact of renin–angiotensin–aldosterone system polymorphisms on myocardial perfusion: Correlations with myocardial single photon emission computed tomography-derived parameters
(2019)Background: Renin–angiotensin–aldosterone system (RAAS) has an important role in atherosclerosis. We investigated the effects of six RAAS gene polymorphisms on myocardial perfusion. Methods and Results: We examined 810 ... -
Long-term prognostic value of Tc-99m tetrofosmin myocardial gated-SPECT imaging in asymptomatic patients after percutaneous coronary intervention
(2008)PURPOSE: To evaluate the long-term prognostic value of Tc-99m tetrofosmin myocardial gated-SPECT in asymptomatic patients after coronary artery stenting. MATERIALS AND METHODS: We included 246 consecutive patients in the ... -
Personalized physiology-guided resuscitation in highly monitored patients with cardiac arrest—the PERSEUS resuscitation protocol
(2019)Resuscitation guidelines remain uniform across all cardiac arrest patients, focusing on the delivery of chest compressions to a standardized rate and depth and algorithmic vasopressor dosing. However, individualizing ...
