Adipose Stromal Cells Injection in the Myocardium for Induction of Revascularization (ADMIRE)

Study Description
Brief Summary:

Treatment of ischemic myocardium has been the subject of intense research in recent years and stem cell therapy is one of the great promises. The InCor laboratory has studied cells from different backgrounds as candidates for cell therapy in the context of myocardial infarction. Evidence in preclinical studies of the application of stromal (mesenchymal) adipose tissue (hASC) in the ischemic heart by both the InCor group (in the animal model in rodents and pigs) and others in the literature suggest relevant benefits on the decrease of deterioration post-infarction. More recently it has been demonstrated that it arises mainly from the formation of new vessels due to paracrine factors, which are secreted by the injected cells. There are currently no studies in Brazil in which the safety of injecting different doses of hASC cells into the heart has been particularly evaluated. Recently, two studies have demonstrated the clinical applicability of hASC in patients with peripheral ischemic disease and stroke.

Thus, the objective of this work will be to test the hypothesis that the implantation of autologous stromal cells derived from adipose tissue combined with myocardial revascularization surgery in patients with coronary artery disease

Criteria

Inclusion Criteria:

  • signing the Informed Consent Form (TCLE)
  • the patient must be a patient with obstructive atherosclerotic coronary artery disease
  • sex: both men and women are eligible-
  • Age: between 18 and 80 years of age
  • the patient should present clinical evidence (angina pectoris or angina equivalent) OR imaging (stress echocardiography, myocardial perfusion scintigraphy, cardiac magnetic resonance imaging) of myocardial ischemia, invasively stratified with coronary angiography
  • the presence of myocardial ischemia should be confirmed by at least 2 (two) distinct diagnostic methods performed within one year of the patient's inclusion in the study
  • the patient is a candidate for myocardial revascularization surgery but coronary obstructive lesions, in their entirety, are NOT amenable for surgical treatment in the opinion of the surgeon (main surgeon), depending on the anatomical type, extent or distal involvement of the lesions OR, even if they can be treated surgically as a whole, an unsatisfactory surgical outcome is anticipated in terms of functional gain (restoration of myocardial perfusion)

Exclusion Criteria:
