Active clinical trials for "Coronary Disease"

Low medication adherence in patients with coronary heart disease increases mortality. This study investigates if an intervention of medication review and counselling can improve patients' medication adherence and treatment results.

A single-centre double-blind placebo-controlled crossover randomised controlled trial to determine the physiological basis of glucagon-like peptide-1 receptor activation on exercise haemodynamics, as manifest through specific electrophysiological parameters measured by serial exercise stress testing, in those patients with reversible myocardial ischaemia and obstructive coronary artery disease confirmed by a baseline exercise test and coronary angiography respectively.

It has been well known that moderate and regular levels of physical activity has a favorable effect on many of the established risk factors related to coronary artery disease (CAD). Given that exercise in the morning has a greater potential for inducing sudden cardiac death and myocardial ischemia, it may be sensible for patients with CAD not to take exercise at this time. Our previous study indicated that the protective effect of exercise in the evening was greater than morning. However, which times of day to exercise could achieve the greatest improvements in lipids and inflammatory markers remains unclear. The purpose of the present study was to investigate the responses of lipid profiles and inflammatory markers to walking at different times of day in sedentary patients with CAD.

Low motivation to exercise is one of the barriers to participation in cardiac rehabilitation. Fear of activity after a cardiac event is associated with low levels of physical activity. This study aimed to develop and validate a scale to measure fear of activity in patients with coronary artery disease.

Identifying the critical lesion of coronary artery disease and determining the interventional plan are significant for reducing adverse cardiovascular adverse events. The assessment of critical lesion requires the consideration of plaque morphology, tissue composition, and endometrial stress which leading to rupture. In summary, accurate assessment of critical lesions has high application value. In this study, patients with critical coronary artery disease were divided into two groups: an accurate assessment group and a simple assessment group, with the aim to compare the diagnosis and treatment efficiency as well as prognosis, potential cardiovascular risk, possible "excessive" intervention.

The study is a two-arm, parallel, randomized clinical trial. The purpose of the study is to evaluate the effectiveness of automated mobile phone text message-based intervention for secondary prevention, including lifestyles modification, medication adherence improvement and risk factors control among coronary heart disease (CHD) patients without diabetes. The participants will be randomized into intervention and control groups in a 1:1 ratio. The intervention group will receive 6 pre-designed text messages per week in addition to usual care for 6 months, while the control group will receive usual care.

A cold season involves higher cardiovascular morbidity and mortality. Several epidemiologic studies have implicated that persons with a cardiac disease, such as coronary artery disease (CAD) may be at higher risk for these adverse health events, but the mechanisms are not well established. Because both exercise and cold exposure stimulates cardiac and circulatory functions it is important to study their interaction especially among people with CAD and whose myocardial oxygen supply and function are weakened. The study examines how recommended health-enhancing upper and lower body exercise and warm-up in combination with cold exposure affects cardiovascular functions of people with CAD. The research includes randomized controlled experiments where the participants are 35-75 year old men with CAD (CCS I-II) and recruited from the Oulu University Hospital. Each participant undergoes four different trials in random order where the temperature (+22°C or -15°C) and the form of exercise (brisk walking at 5.5 km/h or upper body exercise at 30 W), and warm-up regime is varied. The used exercise, clothing and exposure resemble an ordinary wintertime exercise event. Novel techniques are used to broadly assess cardiovascular function before, during and in the recovery phase. The obtained information is synthesized and translated to tailored year-round exercise instructions for people with CAD by the research team including experts from sports sciences, physiology, public and occupational health, clinical sciences and with complementary knowledge in physical activity, effective interventions and cardiovascular function. The study has broad national and international impact on the relatively passive aging population having CAD and residing and working in a cold climate. The produced information enables finding means to activate persons with CAD and where appropriate and safe year-round exercise may reduce or prevent adverse health effects. Health care personnel will have an improved possibility to prescribe physical activity programs for their clients and enabling better instructions of healthy and safe exercise as a way to promote health.

To evaluate the effect of oxycodone and sufentanil in preventing cardiovascular responses to tracheal intubation in the patients with coronary heart disease (CHD).

Background Verapamil is traditionally applied prophylactically in transradial procedures to prevent radial artery spasm. However, verapamil may have side effects and is contraindicated in some clinical settings. Methods: During an investigator-initiated, randomized, double-blind trial, we evaluate the need for preventive verapamil administration. After vascular access is established, patients receive either 5 mg verapamil (n=297) or placebo (n=294). We compare the rate of access site conversions as primary end point using a superiority margin of 5%. Occurrence of code breaks (composite of conversions and unplanned use of verapamil), overall verapamil use, procedural and fluoroscopic times, contrast volume, and subjective pain are investigated as secondary end points.

Air pollution is a major cause of cardiorespiratory morbidity and mortality. The exact components of air pollution that underlie the cardiovascular effects are not yet known, but combustion-derived particulate matter is suspected to be the major cause. Epidemiological studies have shown that exposure to air pollution causes exacerbation of existing cardiorespiratory conditions leading to increased hospital admissions and death. The investigators have recently conducted a series of controlled exposure studies to urban particulate matter and diesel exhaust in healthy volunteers and patients with coronary heart disease. The investigators found that controlled exposure to dilute diesel exhaust in patients with prior myocardial infarction induced asymptomatic myocardial ischaemia with an increase in electrocardiographic measures of myocardial ischaemia. Whilst important, further questions remain: (i) does air pollution exposure exacerbate ischaemia and reduce exercise tolerance in patients with symptomatic angina pectoris, (ii) do "real world" exposures as encountered in the urban environment of major cities have similar effects, and (iii) can a simple face mask intervention to reduce exposure to particulate air pollution improve health outcomes in patients with coronary heart disease?
