Detailed Description:
The standard of care treatment for acute myocardial infarction (AMI) usually includes immediate perfusion, optimal pain relief, oxygen, aspirin or other anti-coagulants, Beta-Blockers, nitrates and Ace-inhibitors. However, because salvaging the viable myocardium is dependent on early reperfusion, only a minority of patients will reach the hospital within the time-window for myocardial rescue. Thus, even if the patient manages their tobacco use, hypertension, lipid levels, diabetes, weight and exercise, many patients will go on to develop Congestive Heart Failure (CHF). Though the medical management for CHF may improve symptoms and slow disease progression, such treatment cannot restore a functioning myocardium. A therapy that could improve the myocardial remodeling process and reduce the incidence or severity of CHF following acute MI would provide a significant benefit. The characteristics and biologic activity of Prochymal®, along with a good safety profile in human trials to date, suggest that Prochymal® may be a good candidate for addressing this unmet medical need.
