Filter by:Maintaining physical activity post-cardiac rehabilitation (CR) has a major role in disease progression and patient prognosis, especially given its potential impact on physical condition. Unfortunately, during a nursing interview carried out 6 months after the CR at the Center Hospitalier de Cholet, we find that 40% do not maintain regular physical activity. This observation is in line with the literature since it emerges respectively at 2 months and 1 year post-CR that between 47% and 59% of patients do not comply with the recommendations in terms of physical activity (Guiraud et al, 2012). However, data suggest that during the post-CR follow-up phase at 6 months, there could be a maintenance of the physical condition assessed via the distance at the 6-minutes walk test (Pavy et al, 2012; Racodon et al, 2019). There is a lack of data on the maintenance of physical condition beyond 6 months since no study has evaluated the maintenance of physical condition at 1 year post-CR by 6-minutes walk test.
Coronary Artery Disease (CAD) is the top killer nowadays. Pressure-wire-based Fractional Flow Reserve (FFR) is the gold standard for measuring ischemia in coronary arteries. CFD-based RuiXin-FFR, which is noninvasive, is developed recently. But its accuracy is not verified. This is a multi-center and prospective study to evaluate the sensitivity, specificity, and accuracy of CFD-based RuiXin-FFR compared with wire-based FFR.
The aim of the study is to assess the effect of evolocumab on coronary plaque morphology using intravascular imaging and gene expression analysis of peripheral blood mononuclear cells (PBMC) in patients with stable CAD on maximally tolerated statin therapy. The study combines multi-modality intravascular imaging approaches and transcriptomic based machine learning algorithms to uncover molecular mechanisms responsible for the beneficial changes in atherosclerotic lesions of patients treated with evolocumab. The primary end-points are the changes from baseline to follow-up in (1) the minimal fibrous cap thickness (FCT) assessed by optical coherence tomography (OCT) and (2) maxLCBI4mm assessed by near-infrared spectroscopy (NIRS) after 26 weeks of evolocumab. The secondary endpoints are the changes in (1) the maximal lipid arc, lipid length, lipid volume index, macrophage accumulation and calcification by OCT; (2) PAV and TAV defined by intravascular ultrasound (IVUS) and (3) Changes in PBMC gene expression.
Investigators evaluated the efficacy of a pilot-tested mHealth intervention to improving medication adherence and health outcomes among patients with coronary heart disease.
Large population cross sectional study between 2019-2020 for 4207 new patients that refer to professor Kojuri cardiovascular clinic in shiraz, Iran, was conducted. Patients were undergone selective coronary angiography from radial artery approach by an expert interventional cardiologist. ABI were measured for all patients. ABI ratio was compared with the results of coronary angiography for patients who underwent coronary angiography to measure specificity and sensitivity.
Ischemia-guided revascularization is the cornerstone of contemporary management of coronary artery disease (CAD). Coronary physiological assessment is advocated in the catheter laboratory to guide percutaneous coronary intervention (PCI), and it is widely accepted that an FFR ≤ 0.80 is a good indicator for vessels to benefit from revascularization. Nevertheless, a significant proportion of PCI patients continue to experience adverse events related to both stented segment and/or residual or diffuse disease. Our group recently demonstrated the feasibility of pullback pressure gradient (PPG) derived from virtual Quantitative Flow Ratio (QFR) pullback curve, which is an index of atherosclerosis functional pattern and can be used to epitomize the pathophysiological pattern of CAD as focal or diffuse. In this regard, the current study will investigate the incremental value of PPG added to QFR haemodynamic assessment in ischemia-causing vessels received PCI in predicting adverse outcomes.
Large population cross sectional study, was conducted between 2018-2020 by attendance of 4526 patients in shiraz, Iran. Patients were undergone selective coronary angiography from radial artery approach by an expert interventional cardiologist. 25-hydroxy vitamin D and Hs-CRP levels were measured for all patients
Background: Office blood pressure (OBP) is used for diagnosing and treating hypertension but ambulatory blood pressure measurement (ABPM) associates more accurately with patient outcome. The optimal blood pressure in patients with coronary artery disease (CAD) is still unknown. Our objective was to investigate whether physician awareness of ABP after percutaneous coronary intervention (PCI) improved BP-control. Methods: A total of 201 patients performed ABPM before and after their PCI follow-up visit. Patients were randomized to open (O) or concealed (C) ABPM results for the physician at the follow-up visit. The change in ABP and antihypertensive medication in relation to baseline ABP was compared between the two groups.
