Filter by:The CLIMATE Observational Study examines to what extent chronically ill patients experience adverse health effects because of heat and whether the patients' specific efforts, somatosensory amplification, self-efficacy, health literacy and commitment to the GP, degree of urbanisation of the patients' administration district and characteristics of the patients' neighborhood are associated with these effects.
SUSPECT is a prospective, single-center, cohort study of 250 military aircrew at the Center for Man in Aviation, Royal Netherlands Air Force. All asymptomatic aircrew (≥40 years) are asked to undergo a coronary CT scan on a voluntary basis, following the exercise electrocardiograms performed at their routine aeromedical examination. Coronary Artery Calcium score (CACS) and CCTA findings are reported.
Randomized, single-blind, single-center, non-inferiority clinical trial to compare target lesion failure (TLF) at 12 months in high bleeding risk patients undergoing elective coronary percutaneous intervention comparing limus-eluting balloon vs. limus-eluting stents.
The use of intra coronary physiological assessment with fractional flow reserve (FFR) is nowadays the standard approach to define ischemia-inducing stenosis and guide myocardial revascularization strategy in patients with coronary artery disease. Further, FFR has been shown to be a strong and independent predictor of major adverse cardiac events after stent implantation. A lower value of FFR after stent implantation is associated with a worse clinical prognosis, without a clearly defined threshold above which clinical follow up are similar for all FFR values. Among 750 patients in the Fractional Flow Reserve Post-Stent Registry, the event rate was 29.5% in patients with FFR<0.80 compared to 9 4.9% in patients with FFR>0.95 (p<0.001). However, FFR remains poorly adopted in many cathlabs, partly because of procedural time, discomfort or sides effect during hyperemia, non-uniform adenosine response and economical constraints. This leads to the validation of resting indices (instantaneous wave-free ratio (iFR), diastolic pressure ratio (dPR), and resting full-cycle ratio (RFR) among others). Those indices evaluate coronary physiology without the use of maximal hyperemia and have 15 slightly different threshold compared to FFR (≤0.89 vs 0.80, for iFR and RFR, and FFR 16 respectively).In the VALIDATE RFR study, a head-to-head comparison of RFR and iFR from a retrospective analysis, diagnostic accuracy of RFR was 97.4% with an area under the curve 1 (AUC) of 99.6%. In the more recent RE-VALIDATE RFR study, 431 patients with 501 lesions 2 were prospectively evaluated for the diagnostic performance of RFR in all-comers patients. Compared to iFR, RFR achieved high diagnostic accuracy, sensitivity and specificity. These are the reasons why we designed a prospective, non-randomized, clinical trial, to better 18 explore the value of RFR before and after PCI in real live and after optimization by post dilation 19 in all-comers patients with coronary artery disease in the Middle East region..
This clinical trial will explore the efficacy and safety of GCSF-mobilized autologous CD34+ cells for the treatment of CMD in adults currently experiencing angina and with no obstructive coronary artery disease. Eligible subjects will receive a single administration of CLBS16 or placebo.
The purpose of this study is to investigate the effects of dapagliflozin therapy on myocardial perfusion reserve (MPR) using dynamic SPECT examination in prediabetic patients with stable CAD. Dapagliflozin therapy versus lifestyle modification improves myocardial perfusion reserve in prediabetic patients with stable CAD.
This observational study will follow participants who completed follow-up in the FOURIER OUTCOMES trial to evaluate the long-term effects of evolocumab treatment. Long-term post-trial (legacy) beneficial effects have been reported with statins, niacin, hypoglycemic therapy and fibrates. Whether similar effects are seen after LDL cholesterol (LDL-c) lowering by PCSK9 inhibition is currently unknown. Evolocumab therapy causes a profound reduction in LDL cholesterol of approximately 60%. Statins have shown legacy effects over 5 years post-trial, including a 7% reduction in total mortality in meta-analysis and 12% reduction in coronary mortality. It would therefore be hypothesized that additional effects beyond the trial period would be conferred by previous evolocumab treatment. It is also important to assess the long-term safety of prior evolocumab treatment.
CHORAL Flow is a randomised, double blinded, placebo-controlled trial of the effects of evolocumab on coronary flow at 12 weeks.
The purpose of the study is to see whether the antibiotic combination of 100mg doxycycline, 500mg azithromycin and 300mg rifabutin is a safe and effective treatment for coronary artery disease which has not responded to 'standard treatment'. Coronary artery disease is the process of plaque build up within the walls of the arteries responsible for supplying the heart with oxygen and nutrients. plaque is usually made up of fatty deposits, minerals and various amounts of tissue and white cells which eventually narrows the artery, reducing blood flow to the heart. The resulting damage and build up of fat leads to inflammation of the arterial wall and eventually the arteries narrow. The researchers involved in this study consider that a pathogen called Chlamydophila pneumoniae, which can live inside cells may cause this inflammation of the arterial wall. The purpose of this study is to see if treatment with this antibiotic combination in patients with CHD is safe and effective in reducing disease severity measured at coronary angiography and improving quality of life. Approximately 60 patients will be involved in this trial. the treatment period is 90 days with a further 90 day follow up period.
In systemic lupus erythematosus (SLE), cardiac manifestations, e.g. coronary artery disease (CAD) and myocarditis are leading causes of morbidity and mortality. The prevalence of subclinical heart disease in SLE is unknown. We studied whether a comprehensive cardiovascular magnetic resonance (CMR) protocol may be useful for early diagnosis of heart disease in SLE patients without known CAD
