Filter by:Calcification artery calcium (CAC) scoring is a valuable tool for determining the risk of major adverse cardiac events. It was found that CAC can be quantitatively assessed, by manual scoring or using deep-learning, on low-dose non ECG-gated, contrast-enhanced or non-enhanced CT scans performed in association of PET acquisition, with a good agreement with standard scans. The purpose of this study is to determine the impact of a systematic coronary artery calcification evaluation in patients undergoing 18F-FDG PET/CT imaging to improve primary prevention of cardiovascular diseases. A visual CAC assessment will be made for each patient, dividing them into four groups: none, mild, moderate or heavy CAC. When possible, a CAC score will be computed. Each patient will complete a questionnaire to collect risk factors, history of cardiovascular diseases and medications.
The study objective is to compare standard CABG to a hybrid revascularization strategy (RA-MIDCAB + PCI) in patients who have multi-vessel CAD and an indication for surgery, but who have a slightly higher risk of post-operative complications.
The goal of this interventional is to assess advantages of the ultrasound examination of the lungs in the early postoperative period in cardiac surgical patients after heart surgeries requiring cardiopulmonary bypass. Evaluation of pulmonary complications and outcomes during mid-term follow-up, as well as comparison of ultrasound examination and traditional roentgenologic methods (X-ray examination and CT of the chest) will be performed. The main question[s] it aims to answer are: - Is ultrasound examination of the lungs a more specific and sensitive method in identification of early postoperative pulmonary complications after on-pump cardiac surgical procedures, in comparison with traditional X-ray methods. - Does early identification of interstitial pulmonary edema (based on number of visualised B-lines in the early postoperative period), influences mid-term outcomes in this cohort of patients Participants will undergo ultrasound examination of the lungs on postoperative day 1, 3, 5 and 7 after heart surgery. Based on ultrasound findings and degree of interstitial pulmonary edema, medical (diuretics, anti-inflammatory, e.t.c) therapy will be modified. Researchers will compare this group of patients with control group, in which ultrasound examination will be performed in the same time frames, but no changes in medical management based on ultrasound findings will be made to see if timely administered medical therapy, based on ultrasound findings, can significantly improve symptoms, hospital lengths of stay and outcomes of this patients.
The objective of HeartFlow's DECIDE Registry is to collect observational data about the management of patients before and after HeartFlow Artificial Intelligence-Quantitative Coronary Plaque Analysis (AI-QCPA).
Patients undergoing coronary angiography for stable or acute coronary disease presentations and eligible for percutaneous coronary intervention (PCI) will be imaged with OCT-NIRAF at baseline and with CCTA 12 months apart to demonstrate that: 1. NIRAF coronary artery signal level (patient, artery, lesion basis) is correlated with the severity of coronary artery disease. 2. NIRAF coronary artery signal level is a predictor of plaque progression on a per patient, per artery, or per lesion basis.
Socioeconomically disadvantaged populations with multiple chronic conditions have high rates of nonadherence to essential chronic disease medications after hospital discharge. Medication nonadherence after hospital discharge is significantly associated with increased mortality and higher rates of readmissions and costs among these patients. Major patient-reported barriers to essential medication use after hospital discharge among low-income individuals are related to social determinants of health (SDOH) and include: 1) financial barriers , 2) transportation barriers, and 3) system-level barriers. Although, medication therapy management services are important during care transitions, these services have not proven effective in improving medication adherence after hospital discharge, highlighting a critical need for innovative interventions. The Medication Affordability, Accessibility, and Availability in Care Transitions (Med AAAction) Study will test the effectiveness of a pharmacy-led care transitions intervention versus usual care through a pragmatic randomized controlled trial of 388 Medicaid and uninsured hospital in-patients with MCC from three large healthcare systems in Tennessee. The intervention will involve: 1) medications with zero copay, 2) bedside delivery then home delivery of medications, and 3) care coordination provided by certified pharmacy technicians/health coaches to assist with medication access, medication reconciliation, and rapid and ongoing primary care follow-up. We will examine the impact of the intervention during 12 months on 1) medication adherence (primary outcome) and 2) rapid primary care follow-up, 30-day readmissions, hospitalizations and emergency department visits, and costs. We will conduct key informant interviews to understand patient experience with the acre received during and after care transitions. By examining effectiveness of the intervention on outcomes including medication adherence, health care utilization, costs, and patient experience, this study will provide valuable results to health systems, payers, and policymakers to assist in future implementation and sustainability of the intervention for socioeconomically disadvantaged populations.
The objective of the study is to compare angiographic outcomes of Selution sirolimus coated balloon (MedAlliance) versus SeQuent Please Neo paclitaxel coated balloon (Bbraun) for the treatment of de novo coronary artery lesions in medium size vessels (>2.00 mm and ≤3.00 mm) with respect to Net Gain (mm) at 12 months follow-up.
This is a multicenter, prospective observational study. Will be collecting data from 90 consecutive patients (aged 25- 60 years ) with and without migraine admitted at our Hospital. Primary aim of the study will be to assess the correlation between migraine and proteomic profiling of plasma and their possible correlation with known cardio and cerebrovascular disease and CV risk factors.
The clinical trial is intended to evaluate the efficacy, safety and economic benefit of coronary lithotripsy compared to other additional procedures (cutting or super high pressure balloon angioplasty, ablative procedures) in lesion preparation and interventional treatment of severely calcified coronary stenoses.
Ischaemic heart disease (IHD) and degenerative brain disease are two major sources of death and disability affecting all countries. While the consequences of obstructive disease in major vessels supplying blood to both organs have been widely documented, less attention has been paid to disease processes affecting the microcirculation that may affect cardiac and cerebral function. Yet, over the last decade significant progress has been made in understanding the substrate of microvascular disease in both organs. In the heart, arteriolar thickening and capillary rarefaction that reduce the conductance of the microvasculature and its ability to vasodilate in response to increased myocardial oxygen demands constitute the leading cause of coronary microvascular dysfunction (CMD). In the brain, concentric hyaline thickening of deep penetrating small arteries (arteriolosclerosis) with associated fibrosis of the vessel wall constitutes the most frequent substrate for cerebral small vessel disease (CSVD). Of note, both CMD and CSVD share common risk factors, such as age, hypertension, and diabetes.3 These factors might have a common effect on the microvascular domain of cardiac and cerebral vascular beds. Although a potential link between both conditions has been hypothesized based on the similarities between pathological changes and risk factors, advance in knowledge exploring this has been hampered by lacking objective evidence of CMD and pathological brain changes indicative of CSVD in prior research studies. Thus, the relationship between CMD and CSVD is unknown. The main objective of this study was to analyse the relationship between cerebrovascular disease and CMD in patients with atherosclerotic coronary artery disease (CAD).
