Risk stratification for free

Cell-free DNA as a promising marker for risk stratification of pulmonary embolism

Arnalich and colleagues reported an interesting clinical study that evaluated cell-free plasma mitochondrial and nuclear DNA concentrations in patients with pulmonary embolism (PE) [1]. They found increased circulating mitochondrial and nuclear DNA levels, as well as alterations in other cardiac biomarkers (heart-type fatty acidbinding protein and troponin I) in patients with massive PE compare...

Risk Stratification for Cardiac Arrhythmia Patients

Risk stratification for adult congenital heart surgery.

OBJECTIVE At this moment, no risk stratification models are available for adult congenital cardiac surgery. This study aims to identify a suitable stratification tool for the adult congenital heart surgery population. Pediatric congenital cardiac surgery score models were therefore tested in an adult congenital population. In addition, an age component was added to these models and performance ...

Myocardial perfusion imaging for preoperative risk stratification.

This review considers the changing nature of surgical risk assessment and the definition of risk; discusses the pathophysiology of perioperative myocardial infarction in relation to tests of coronary flow reserve; surveys the extensive literature on preoperative myocardial perfusion imaging (MPI) and outlines key trends; presents practical points on image interpretation; addresses the needs of ...

Ambulatory blood pressure for cardiovascular risk stratification.

Ambulatory blood pressure (ABP) monitoring is increasingly recognized as a valuable tool to refine prediction of cardiovascular risk related to blood pressure (BP).1 After the first landmark study published by Perloff and colleagues 24 years ago,2 several longitudinal event-based studies provided unequivocal evidence of an independent association between ABP and risk of cardiovascular disease. ...
