Active clinical trials for "Myocardial Ischemia"

Cardiac surgery using heart and lung machine produces an inflammatory reaction in the body. This leads in few percent of cases to heart, lung, and kidney disturbances that potentially causes death. White blood cells in contact with the heart and lung machine and external surfaces release mediators partly responsible for this. Blood collected by the suction and the blood remaining in the heart and lung machine after its use, can be cleaned by a cell saver before reinfusion, and this might reduce the inflammatory response.

The main objective of this clinical trial is to evaluate the effectiveness and cost-effectiveness of adding ozone therapy to standard management of patients with advanced ischemic heart disease refractory to medical and surgical treatment.

When a patient is newly diagnosed of systolic dysfunction without obvious etiology (such as rhythmic, ischemic, or valvular disease), most of the time a coronary angiography is performed. In this situation, the investigators aim to evaluate a strategy with CMR as the front line exam, and invasive coronary angiography performed only in case of ischemic scar on CMR

The BIOFLOW-VIII registry is a post-market clinical evaluation of the Orsiro Mission stent in subjects requiring coronary revascularization with Drug Eluting Stents (DES).

The International Study of Comparative Health Effectiveness with Medical and Invasive Approaches (ISCHEMIA) Extended Follow-up (ISCHEMIA-EXTEND) is the long-term follow-up of randomized, surviving participants in ISCHEMIA. ISCHEMIA was an NHLBI-supported trial that randomized 5,179 participants with stable ischemic heart disease to two different management strategies: 1) an initial invasive strategy (INV) of cardiac catheterization and revascularization when feasible plus guideline-directed medical therapy (GDMT), or 2) an initial conservative strategy (CON) of GDMT. The trial did not demonstrate a reduction in the primary endpoint with an initial invasive strategy. There was an excess of procedural myocardial infarction (MI) and a reduction in spontaneous MI in the INV group. Prior evidence suggests that spontaneous MI carries a higher risk of subsequent death than procedural MI. There was a late separation in the cardiovascular (CV) mortality curves over a median of 3.2 years follow-up in ISCHEMIA. The MI incidence curves crossed at approximately 2 years. However, during the trial follow-up phase there were excess non-CV deaths in the invasive strategy. Therefore, it is imperative to ascertain long-term vital status to provide patients and clinicians with robust evidence on whether there are differences between management strategies and to increase precision around the treatment effect estimates for risk of all-cause, CV and non-CV death over the long-term. Overarching Goal: To assess the effect of an initial invasive strategy on long-term all-cause, CV and non-CV mortality compared with an initial conservative strategy in SIHD patients with at least moderate ischemia on stress testing, over 10 years median follow-up.

This study is to evaluation the efficacy and safety of Zotarolimus-Eluting Stent in patients with long coronary artery disease of 25 mm or longer.

Randomized, single-blind, single-center, non-inferiority clinical trial to compare target lesion failure (TLF) at 12 months in high bleeding risk patients undergoing elective coronary percutaneous intervention comparing limus-eluting balloon vs. limus-eluting stents.

Oat fibre has been shown to lower cholesterol and may have cardioprotective effects. However, whether this translates to actual cardiovascular risk reduction is unclear, as there is a lack of controlled human trials. To address this uncertainty, the investigator proposes to use established cardiovascular disease risk scores, such as those recommended by the Canadian Cardiovascular Society and other clinical practice groups, to create composite risk scores in assessing future risk. The data on oat fibre will be collected through a systematic review of controlled trials, composite cardiovascular risk scores will be calculated for each eligible study, and meta-analyses will be conducted to assess the overall effect. The findings generated by this proposed knowledge synthesis will help improve the health of consumers through informing evidence-based guidelines and improving health outcomes by educating healthcare providers and patients, stimulating industry innovation, and guiding future research design.

Randomised placebo-controlled study of efficiency and safety of bone marrow mononuclear cells transplantation by intramyocardial multiple precision injection in ischemic heart failure patients.

The primary objective of this study is to compare the rate of device-oriented composite consisted of cardiac death, myocardial infarction not clearly attributable to a nontarget vessel, and clinically indicated target lesion revascularization among the patients treated with EES, ZES-R, or BES at 24-month clinical follow-up post-index procedure. Trial end points are summarized in Table I. The hypothesis is that BES is equivalent to EES or BES is equivalent to ZES-R at the primary end point.
