Filter by:Clinical study: - Methods: observational transversal two-arm cohort study including adults living with HIV (PLHIV) and HIV negative subjects (HIV-) at intermediate cardiovascular risk. No study specific interventions were performed. - Participants: consecutively recruited at two large public hospitals in Paris and Annecy, France where participants were referred for routine cardiac risk stratification. - Recruitment: was from June 2013 until April 2016. - Data: anonymous study data were collected during the ambulatory visit. No follow-up was conducted. Study objectives: - Primary: compare coronary artery calcification (CAC) score between PLHIV and HIV- in order to bridge gaps in current knowledge. - Secondary: assess parameters linked to CAC score including predictors and their prevalence, association with carotid/femoral atherosclerosis, and cardiovascular risk scores (ASCVD and HEART score). Study hypotheses: - Primary: CAC scores would not be different between PLHIV and HIV- - Secondary: prevalence of traditional CV risk factors would be lower in PLHIV but that HIV-related nontraditional CV risk factors (including lower grade chronic inflammation, immune dysregulation, and ARV exposure duration) would be associated with higher CAC scores and higher CV risk scores Study Rational: - PLHIV have an increased risk of atherosclerotic cardiovascular events compared to the general population. Primary prevention for PLHIV is important but challenging as traditional cardiovascular risk scores do not account for HIV-related factors. - Computed tomography coronary artery calcium (CAC) score using the Agatston score is useful for detecting and quantifying coronary calcifications. In the general population, CAC score is predictive of future cardiovascular events.
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.
Previous studies have suggested that restenosis (RS) after stenting is mainly due to smooth muscle cell proliferation and migration, but recent evidence suggests that in-stent restenosis（ISR） is associated with a number of factors. Coronary artery calcification is an independent predictor of ischaemia-mediated revascularisation 1 year after percutaneous coronary intervention (PCI) following RS.The characteristics of new neointima in patients with in-stent restenosis of calcified lesions are important issues to explore
Does an educational intervention for untreated COPD and cardiovascular disease which is integrated in an existing lung cancer screening program improve guideline concordant medication adherence at 12 months
Coronary artery narrowings interfere with blood flow to the heart which can cause chest pain and heart attacks. Cardiologists can treat these narrowings with balloons and stents. However, some narrowings can become very calcified and hard making treatment with balloons and stents difficult. Rotational atherectomy is a tool to treat calcific coronary disease. It uses an ablative drill to break down the hardened plaques inside the coronary arteries facilitating subsequent treatment with balloons and stents. However, during this procedure patients can experience a slow heart rate which may compromise procedural safety. Cardiologists may use a temporary pacemaker that is inserted by separately accessing the heart through a large vein usually from the leg. This maintains a safe heart rate throughout the procedure. However, inserting the temporary pacemaker is associated with additional complications. We have developed and propose an alternative strategy to provide a temporary safety pacemaker during rotational atherectomy without the need for inserting an additional pacemaker.
Percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation has become the dominant treatment strategy for patients with acute and chronic coronary artery disease (CAD) requiring revascularization. Nonetheless, PCI with stent implantation has some limitations and especially patients with severely calcified coronary lesions (approximately 10-20% of all patients with CAD) have an elevated risk for adverse outcomes, including target lesion failure (TLF) and stent thrombosis (ST). Several dedicated PCI devices have been developed for treatment of severely calcified lesions. Whereas especially two of them have shown promising results in smaller, prospective studies. First, the super high-pressure NC PCI balloon (OPN™ NC, SIS Medical AG, Frauenfeld, Switzerland) has been shown to represent an effective and safe device for lesion preparation. Second, the lately introduced Shockwave intravascular lithotripsy (IVL)™ balloon catheter (Shockwave Medical, Santa Clara, CA, USA) appears to be a safe and efficient alternative device for treatment of calcified coronary lesions. However, it remains unknown, if the OPN™ NC balloon is non-inferior to to IVL regarding lesion preparation and completeness of stent expansion in severely calcified lesions.
Calcified lesions are very frequent among coronary artery disease stenotic lesions. The prevalence of calcifications ranges from 30 to 40% (by angiography evaluation) but is higher when analyzed by intra coronary imaging. Calcified lesions are very frequent among coronary artery disease stenotic lesions. The prevalence of calcifications ranges from 30 to 40% (by angiography evaluation) but is higher when analyzed by intra coronary imaging. The presence of calcifications increases the risk of adverse evolution after PCI , including stent restenosis, thrombosis and need for repeat revascularisation. Specific and appropriate tools can be used for calcified lesions management , including high pressure non compliant balloons, intravascular lithotripsy and rotablator. Intra vascular OCT has a high sensitivity and specificity for calcium detection among coronary artery lesions. Compared to IVUS, OCT allows a better quantification of calcium sheets (depth extension ) . Several intra coronary imaging based calcified lesions management algorithms have been proposed , but none have been validated in clinical practice.
The aim of the study is to compare ESC recommendations on cardiovascular (CV) risk stratification with the achievement of a CAC (Coronary Artery Calcification). The development of a CAC, currently not systematically offered to these patients to refine CV risk, could make it possible to offer more intensive management of CV risk facors for patients who objectively have a high CV risk as evidenced by a high coronary calcium score. LDL target recommandations have become more aggressive with a very high level of evidence in type 2 diabetic patients but low in type 1 diabetic patients because there is no specific CV intervention study for T1D patients. These recommendations have far-reaching consequences because they would justify introducing in young type 1 diabetic patients, considered from the outset to be at moderate cardiovascular risk (young T1DM <35 years old) or even at high cardiovascular risk (duration of diabetes > 10 years) or very high cardiovascular risk (duration of diabetes > 20 years), treatment with statins or even aspirin, based only on the length of time they have had diabetes. The realization of a CAC, currently not systematically offered to these patients to refine CV risk, could make it possible to propose a more intensive management of CV risk factors for patients with objectively high CV risk attested by a high coronary calcium score. In this case the introduction of treatment with statins would be indicated.
The purpose of this study is to examine the effect of menaquinone-7 (MK-7) supplementation on cardiovascular, metabolic, and bone health.
The IVL-Dragon Registry was a multicenter study that enrolled consecutive patients with stent underexpansion treated with IVL in high-volume PCI centers. The primary efficacy endpoint was clinical success, defined as a reduction of stent underexpansion to <30% with no evidence of in-hospital device-oriented composite end point (DOCE) (defined as a composite of cardiac death, target lesion revascularization, and target vessel myocardial infarction).
