Multi-Ethnic Study of Atherosclerosis (MESA)
AtherosclerosisCardiovascular Diseases10 moreThe Multi-Ethnic Study of Atherosclerosis (MESA) was initiated to study the correlates, predictors, and progression of subclinical cardiovascular disease (CVD) (disease detected non-invasively before it has produced clinical signs and symptoms) in a diverse population-based sample of men and women aged 45-84 who had no evidence of clinical CVD at baseline (www.mesa-nhlbi.org). During 2000-2002, 6,814 participants were recruited from six field centers (Forsyth County, NC; Northern Manhattan and the Bronx, NY; Baltimore City and Baltimore County, MD; St. Paul, MN; Chicago, IL; and Los Angeles County, CA). The ethnic composition of the recruited cohort was 38% Caucasian, 28% African American, 22% Hispanic, and 12% Chinese. An extensive baseline exam focused on critical CVD risk factors and subclinical disease measures. Five subsequent exams took place through 2018 to assess changes in these measures and to explore new innovative research questions. Cohort members are contacted annually to obtain information about intervening hospitalizations and outpatient cardiovascular-related procedures. Relevant medical records are abstracted and reviewed and clinical endpoints of interest are adjudicated. The study is comprised of one Coordinating Center, six Field Centers and one biospecimen repository.

Comparing TR Band to Statseal in Conjunction With TR Band II
Arterial OcclusionCardiovascular Diseases4 moreThe purpose of this clinical study is to compare how well two different devices for achieving hemostasis perform in patients undergoing transradial procedures. Both devices are approved by the FDA for this use, and have already been used by clinicians on patients undergoing transradial procedures. It is believed that the use of both devices in combination compared to the hemostasis band (TR band) alone will shorten the time that it takes to 'seal' the artery, resulting in a shorter period of time that you would need to wear the hemostasis band.

Singapore Cardiac Longitudinal Outcomes Database
Coronary Artery DiseaseCongestive Heart Failure1 moreThe research project aims to perform data extraction, integration and analysis across multiple clinical, administrative, financial and pharmacy databases in the participating institutions. The key data components will include clinical cardiovascular specific data, procedural data, financial and administrative data (e.g. cost of medications and supplies, length of stay, diagnosis codes etc.), short-to-long term clinical outcomes (including hospital re-admissions, cardiovascular events, death), and quality-of-care indices (e.g. compliance to guideline-recommended therapy and medications). The research project will involve all patients proven and/or suspected with coronary artery disease (CAD), congestive heart failure (CHF) and atrial fibrillation (AF) admitted to National Heart Centre Singapore (NHCS) and NUH.

Comparison of Scoring Balloon and Conventional Balloon Predilation Before Drug Coated Balloon for...
Coronary Artery DiseaseThis study is designed to investigate whether scoring balloon (non-slip element, NSE) predilation compared to non-compliant (NC) balloon predilation for de novo lesion in patients with high bleeding risk and planning to receive drug-coated balloon (DCB) treatment will lead to lower change in minimal lumen area (MLA) at 6 months by intravascular ultrasound (IVUS).

Prognostic Impact of Physical Activity Patterns After Percutaneous Coronary Intervention (PIPAP...
Physical ActivityCoronary Artery DiseasePhysical activity monitoring after coronary bypass grafting and other major surgeries has been found to be predictive for hospital readmission and adverse outcome. In patients after percutaneous coronary intervention (PCI) it has been found that a patient reported activity score is predictive of 3 year major adverse coronary event (MACE). It is not known whether physical activity shortly after discharge from PCI is predictive of one-year MACE. Early identification of patients at increased risk of MACE would facilitate the intensification of preventive strategies in these patients. Primary objective is the quantification of physical activity (daily steps) during the first two weeks after hospital discharge as a predictor for MACE at one year. Secondary objectives are: 1) Comparison between daily steps and objectively measured activity counts (divided in time spent in moderate-to-vigorous activity, light activity and sedentary activity), as well as patient reported activity; 2) Association of daily steps after one year with reaching targets for systolic blood pressure, low-density lipoprotein cholesterol (LDL-C), body mass index (BMI) and glycated haemoglobin (HbA1c); 3) Comparison of daily steps after hospital discharge and MACE between non cardiac rehabilitation (CR), conventional hospital based CR, tele-CR and modular CR participants; 4) Comparison of daily steps at one year after hospital discharge in different CR groups.

Role of Glutamine as Myocardial Protector in Elective On-Pump Coronary Artery Bypass Graft Surgery...
Coronary Artery BypassCardiopulmonary Bypass1 moreCoronary artery disease has the highest mortality rate worldwide and coronary artery bypass grafting (CABG) is the most common cardiac surgery performed in patients with coronary artery disease to revascularize the heart. Despite of improvement in operation techniques, cardioplegia, cardiopulmonary bypass (CPB), myocardial injury related to on-pump CABG is still prominent. In patient with low ejection fraction undergone on-pump CABG, myocardial injury is related to worse outcome and prognosis during peri-operative and post-operative period. On-pump CABG patients with low ejection fraction has increased (up to four times higher) post-operative in hospital mortality rate compared to patient with normal ejection fraction. Administration of intravenous glutamine had been documented in reducing myocardial damage during cardiac surgery and previous studies indicated that glutamine can protect against myocardial injury by various mechanism during ischemia and reperfusion. The purpose of this study to determine whether intravenous glutamine could prevent the decline of plasma glutamine level, reduce myocardial damage, improve hemodynamic profile, and reduce morbidity of on-pump CABG in patients with low ejection fraction.

The Effect of Nicorandil on Left Ventricular Myocardial Strain in Patients With Coronary Chronic...
Coronary Artery DiseaseBackground Nicorandil is recommended as a second-line treatment for stable angina, but randomized-controlled trials (RCTs) to evaluate the benefit of nicorandil for patients with chronic total occlusion (CTO) are still lack. Objective To determine whether nicorandil can improve left ventricular myocardial strain in patients with CTO. Methods Patients with CTO were included and were randomized to the nicorandil group and the control group. Nicorandil was given orally 15 mg/day for 3 months in the nicorandil group. 3-dimentional-speckle tracking echocardiography (3D-STE) and the Seattle angina questionnaire (SAQ) survey were performed at baseline and at 3 months. Participants were randomized according to an IBM SPSS23.0-generated randomization schedule, with a 1:1 allocation to the nicorandil group or the control group.
