The OPTIMUM registry is a minimal risk observational study that uses a prospective cohort design to follow patients who have multivessel or left main coronary artery disease ("surgical anatomy" according to ACC/AHA Appropriateness Criteria for PCI12) and are deemed ineligible for coronary artery bypass surgery. It is anticipated that 20 sites will be selected to participate in the registry from a national network of leading centers across the United States with recognized expertise in both complex PCI and coronary artery bypass surgery. We will invite leading cardiac centers, as defined by US News and World reports rankings for heart care. Additional sites may be added to meet the target enrollment goal.
In the aging population, the prevalence of chronic diseases and multimorbidity has become common. Therefore, the planning and coordination of care have become more important. However, it is not known what kind of treatment plan should be and what kind of patients would benefit most of it. This research focuses on the participatory patient care planning in primary health care. In general, the participatory patient care planning (PPCP) aims to engage patients in self-care, to improve the collaboration between patients and professionals and to improve the use of resources. The present study investigates the feasibility and effectiveness of the PPCP. The specific research questions of the present study are: Does the PPCP have an impact on the patient's quality of life? Does the PPCP improve the quality of care in management of chronic diseases? Does the PPCP improve patient's commitment with self-care? Does the PPCP impact on the use of health care services? The data consists of people aged at least 18 years living in the municipality of Siilinjärvi with diabetes, coronary heart disease or hypertension and who are recorded in in Siilinjärvi Health Care Center electronic patient record. The participating patients are recruited from those who contacts SiiIinjärvi Health Care Center in order to have a follow-up visit because of the treatment of their disease. This study aims to recruit 700 patients. The participants are allocated into the intervention group and into the control group receiving usual care. Intervention consists of the PPCP. This includes the patient activation questionnaire form, a visit to the nurse who conducts the measurements (blood pressure, waist measurement, weight and length) and a visit to the general practitioner who discusses and agrees with the patient about the treatment goals and follow-up resulting in the written PPCP. The main out-come measures are the quality of health related life measured with the 15D; the level of patient's activity in self-care with the Patient Activation Measurement (PAM); life satisfaction, self-rated health, a reduction in productivity with the Work Productivity and Activity Impairment Questionnaire (WPAI: GH), and the disease specific measures (blood pressure, HbA1C, LDL-cholesterol, body mass index and waist measurement). In addition, pain intensity and interference (NRS 0-10), mood (BDI-21), the number of visits and phone calls and referrals are measured.
Coronary artery disease is often treated by implantation of permanent metallic stents.Coronary stents are required in the early healing phase after balloon dilatation but constitute a lifelong foreign body. New bioresorbable stents have been developed and are believed to improve long-term safety. The purpose of this study is to compare the safety and vessel healing after treatment of simple bifurcation lesions with the CE-marked bioresorbable stents Absorb and Desolve.
To compare the MT005 (MiStent) with the XIENCE with respect to target lesion failure (TLF) at 12 months in a non-inferiority trial in a "real world" patient population and to confirm that the domestic extrapolation of the DESSOLVE III study results is valid.
The aim of this study is to analyze metabolomic pattern of patients after cardiac stress in order to detect differences based on the type of stress (physical or pharmacological with adenosine agonists) and result of test (positive or negative for ischemia) and to indentify biochemical markers with prognostic value. Clinical data of enrolled patients regarding demographics, cardiovascular risk factors, pretest probability and previous cardiovascular disease will be recorded. Follow up will be at one, three and five years and will be performed by clinical recordings or phone call when necessary. Blood samples of patients undergoing myocardial perfusion SPECT (Single Photon Emission Computed Tomography) are taken before, immediately after stress and 2h after stress. Serum samples will be analyzed by nuclear magnetic resonance in order to know metabolomic profile.
There are no current alternatives to diagnostic contrast-requiring imaging for patients with an eGFR <30mL/min due to the association of gadolinium-based imaging modalities to nephrogenic systemic fibrosis and iodinated contrast-induced kidney injury. Ferumoxytol-enhanced imaging may offer an alternative approach.
Although current guidelines recommend fractional flow reserve (FFR) to identify haemodynamically relevant coronary lesion(s) in stable patients when evidence of ischaemia is not available (Class I, Level of Evidence: A), no published study has assessed the usefulness of FFR to guide percutaneous coronary intervention (PCI) in ST-elevation myocardial infarction (STEMI) patients with multi-vessel disease (MVD). The main objective of this study is to determine whether, in STEMI patients with MVD amenable to PCI, the use of FFR in addition to angiography will improve cardiovascular outcomes, compared with the current practice of angiography- guided PCI, by improving the appropriateness of revascularisations by assessing the relevance of non-culprit lesions in the context of STEMI with multivessel coronary artery disease. The secondary objective is to assess the safety and the cost-effectiveness of the FFR-guided strategy compared to the angiography-guided strategy.
The Bifurcation ABSORB OCT Trial is a prospective, randomized (1:1) evaluation of the efficacy and performance of single ABSORB everolimus eluting bioresorbable vascular scaffold provisional strategy in the treatment of (a) coronary bifurcation lesion(s) in consecutive subjects with and without fenestration towards the side branch. Patients included in this study will be divided into three different cohorts: - Cohort A (patient 1-20): Angiographic FU with OCT at 12 months. - Cohort B (patient 21-40): Angiographic FU with OCT at 24 months. - Cohort C (patient 41-60): Angiographic FU with OCT at 36 months. All patients will also have telephone FU at 30 days, 12, 24 and 36 months. Inclusion of patients in the BISORB OCT trial stopped in November 2016 after safety concerns of the ABSORB BVS were reported. BISORB OCT included 3 patients, which were all included in the Academic Medical Center
The DuraGraft® Registry is a European registry of patients who have undergone CABG and whose vascular grafts have been treated with DuraGraft. All participating sites will be from countries in Europe. The DuraGraft Registry will collect pre-CABG, intraoperative and post-operative data, major post-CABG cardiovascular adverse events, health economic outcomes and patient reported quality of life over a period of 5 years.
