Active clinical trials for "Coronary Artery Disease"

Ambulation following surgery has been found to be beneficial for patients; however, nurses and doctors struggle with getting post-operative, hospitalized patients to walk on their own. One promising strategy to address this might be an ambulation orderly, an employee whose single responsibility is to assure that patients walk 3-4 times per day. However, the effect of the ambulation orderly on post-operative physical activity has not yet been described. It is important to quantify what the ambulation orderly does in order to assess if this is an effective method for helping patients walk. As a result, the investigators will perform a pilot randomized controlled trial to test the effects of an ambulation orderly in patients hospitalized with recent cardiac surgery. Half of the patients will be assigned to walk with the ambulation orderly 3-4 times/day and the control group will be given standard nursing encouragement and assistance and encouragement to walk. The investigators will evaluate the average total daily step counts (over the hospital course, usually 4-7 days) and the change in walking distance between a baseline and a final 6 minute walk test. The investigators will also evaluate exercise physiologic parameters (heart rate, oxygen saturation) during ambulation, patient functional independence, and patient satisfaction.

This is a prospective interventional study to assess the effect of sarpogrelate compared with aspirin in Korean type 2 diabetic patients with atherosclerosis.

Using a randomized clinical trial with 3 groups, the investigators will conduct a head-to-head evaluation of two different theoretically-based interventions, SystemCHANGE and CHANGE+, as compared to Usual Care to improve the adoption and maintenance of exercise in older cardiac patients. SystemCHANGE, a novel intervention that focuses on environmental change uses System Improvement strategies to increase exercise, will be compared to CHANGE+ (an intervention based contemporary cognitive behavioral strategies). Study questions are: (1) Is there a difference between SystemCHANGE, CHANGE+ and Usual Care in exercise adoption when controlling for covariates (age, race, functional capacity, body fat, co-morbidity, muscle or joint pain, exercise experience, home and neighborhood environment, and depression), for individuals following a cardiac rehabilitation program (CRP)? (2) Is there a difference between SystemCHANGE, CHANGE+, and Usual Care in exercise maintenance when controlling for covariates? (3) Do system changes, social support for exercise, problem-solving skills, motivation, health beliefs, and exercise self-efficacy mediate the effects of SystemCHANGE, CHANGE+, or Usual Care on exercise adoption? (4) Do system changes, social support for exercise, problem-solving skills, motivation, health beliefs, and exercise self-efficacy mediate the effects of SystemCHANGE, CHANGE+ and CHANGE+ interventions in terms of health care spending, labor force participation and earnings, and household productivity? Older persons (N=420) recovering from cardiac events will be randomly assigned to the three groups. Measures of exercise adoption and maintenance (# of metabolic equivalents {METS} expended, and whether or not a subject remains exercising) will be taken for 1 year after completion of a CRP using heart rate wristwatch monitors, exercise diaries, and 7-Day Recall Survey. The effect of covariates also will be assessed. Mechanisms by which the interventions achieve their effects will be determined. Multivariate analyses will examine and compare the effects of the interventions over time. A cost-effectiveness analysis also will be conducted.

The aim of this study is to prove that using a CytoSorb(TM) filter in the cardiopulmonary circuit attenuates the inflammatory response to extracorporeal circulation in patients undergoing cardiac surgery. The hypothesis is that removing cytokines from patients' blood by the CytoSorb device significantly improves circulation and outcome in patients undergoing on-pump cardiac surgery.

The primary objective of the BIODEGRADE study is to evaluate clinical efficacy of the Orsiro drug-eluting stent compared with Biomatrix drug-eluting stent, both of which have biodegradable polymer for the treatment of all-comers' coronary artery diseases.

The purpose of this clinical research study is the design of a novel modular hybrid system extracorporeal circulation circuit for open heart procedures that could easily be converted from a closed to a semi-closed circuit according to the indication. This could expand the potential of minimal extracorporeal circulation and could ultimately become the new standard circuit in performing every type of cardiac surgery.

Assess the pharmacodynamic effect of ticagrelor vs. Clopidogrel in American Indian patients with stable coronary artery disease.

The ABSORB III RCT is a prospective randomized, single-blind, multi-center trial. It is the pivotal trial to support the US pre-market approval (PMA) of Absorb™ Bioresorbable Vascular Scaffold (BVS). The ABSORB III includes additional two trials i.e. ABSORB III PK (pharmacokinetics) sub-study and ABSORB IV RCT trial which are maintained under one protocol because both trial designs are related, ABSORB IV is the continuation of ABSORB III and the data from ABSORB III and ABSORB IV will be pooled to support the ABSORB IV primary endpoint. Both the trials will evaluate the safety and effectiveness of Absorb BVS.

Tongxinluo is a kind of Chinese patent drug,which could promote blood circulation.Recent reports suggested that tongxinluo's effectiveness in reducing the thrombin activity.In this prospective randomized study,all patients in control group will receive blank placebo ,all patients in test group will receive tongxinluo.All patients will be followed up for one year.

Individuals with serious mental illnesses (SMI) face high rates of medical comorbidity as well as challenges in managing these conditions. A growing workforce of certified peer specialists is available to help these individuals more effectively manage their health and health care. However, there is little existing research examining the effectiveness of peer-led medical self-management programs for this population. in this trial, participants were randomized to either the Health and Recovery Peer program (HARP), a medical disease self-management program led by certified peer specialists, or to care as usual. Assessments were conducted at baseline, 3 months, and 6 months.
