Filter by:People with Coronary Artery Disease (CAD) have narrow or blocked arteries that supply blood to the heart. Reduced blood flow to the heart muscle from CAD can cause chest pain or aching, especially with exercise or activity. CAD can lead to weakening of the heart muscle or heart failure, and a higher risk of heart attack or death. Certain proteins in the blood, known as biomarkers, can be found in people with CAD. Higher levels of these biomarkers are associated with a greater risk of complications from CAD. The purpose of this study is to see if a customized treatment based on biomarkers will reduce the biomarker levels and lead to lower risk of complications from CAD.
Postoperative cardiovascular complications are common after noncardiac surgery. The association between perioperative inflammation and the occurrence of cardiovascular complications after surgery is still unknown. Therefore, we will evaluate as our primary aim the association between patients with increased postoperative inflammation, assessed with C-reactive protein measurements, and the occurrence of major cardiovascular complications after noncardiac surgery. We will further evaluate the influence of perioperative inflammation on the occurrence of postoperative acute kidney injury. We will also evaluate the association between inflammation and the influence on Days-At-Home within 30 days. Furthermore, we will evaluate the association between increased inflammatory biomarkers and postoperative N-terminal pro brain natriuretic peptide (NT-proBNP) concentration.
Adverse Childhood Experiences (ACEs) are potentially harmful events occurring during childhood that have been associated with chronic physical conditions in adulthood, including coronary artery disease (CAD). ACEs may constitute a portion of the remaining unexplained residual risk for CAD in adults. Identifying a means of addressing these experiences may mitigate their health consequences and result in improved cardiovascular outcomes. The primary objective of this study is to determine if patients who undergo ACE screening experience improved quality of life compared to patients who undergo conventional lifestyle assessment. This will be a single-centre, pragmatic, single-blinded (i.e. data analysts), 1:1, pilot randomized control trial.
After lung resection, troponin elevation may be regulated by mechanisms other than myocardial ischemia. Perioperative natriuretic peptides measurement may help identify changes in ventricular function during thoracic surgery. Integrating both cardiac biomarkers may improve the predictive value for cardiovascular complications after lung resection.
A single centre prospective trial in which patients with a prior PCI for stable CAD who are referred for invasive angiography will undergo state-of-the art CCTA and dynamic CT perfusion. Subsequently invasive FFR and iFR measurements will be routinely performed in each coronary vessel.
The FLOW-PROMOTE Study is an investigator-initiated, Danish multicenter study of patients with stable chest pain investigating whether lipid lowering is associated with recovery of impaired coronary flow as assessed by CT derived fractional flow reserve (FFRCT).
E5TION will evaluate the efficacy, safety and tolerability of tailored two regimens (prasugrel 5mg/d vs. ticagrelor 60mg bid) in high-risk patients undergoing PCI (CHIP: COmplex and Higher-Risk Indicated PCI/PatieNts).
Mountain sport activities as for example hiking or skiing may involve the risk of adverse health events especially in older people not accustomed to the specific mountain sport at altitude or people with pre-existing health issues. Increased activation of the sympathetic nervous system and abrupt changes in heart rate and blood pressure are thought to trigger these adverse effects. Preventive measures include regular physical activity (i.e. training) and adequate medical treatment. Hypoxia pre-adaptation (e.g., pre-adapt one night at moderate altitude) and pre-conditioning (e.g., intermittent hypoxia (IH) training), which was shown to lead to some favorable sympathetic nervous system, ventilatory and metabolic adaptations and additionally exerts anti-inflammatory action, could be hypothesized of being a further preventive measure. The aim of this research project is to investigate whether intermittent hypoxia pre-conditioning or sleeping one night at altitude (i.e., current recommendation before practicing mountain leisure sports in the elderly) is able to increase oxygen saturation during passive hypoxia exposure and during simulated hiking and skiing at altitude. Additionally, it is aimed to investigate whether such procedure reduces the physiological responses (i.e., heart rate, its variability and blood pressure (including baroreflex sensitivity) responses as well as metabolic, ventilatory, inflammatory and redox responses) during these activities.
This study is about testing whether exercise will improve fitness and lessen risk factors related to heart disease, diabetes, and obesity in Latina breast cancer survivors.
The purpose of the DYNAMITE trial (Dynamic CT stress myocardial perfusion, CT fractional flow reserve (FFR-CT) and coronary CT angiography for optimized treatment strategy in patients with chest pain syndromes) is to determine the ability of combined anatomical and functional cardiac CT imaging to improve morbidity and mortality in patients with suspected or known ischemic heart disease.
