Research Protocol for Cardiovascular Diseases
Cardiovascular disease can be modeled as maladaptive cardiac remodeling, where ischemic injury or pressure overload activates inflammatory signaling, fibroblast activation, extracellular-matrix deposition, cardiomyocyte hypertrophy, vascular remodeling, and progressive ventricular dysfunction. The TGF-β/SMAD axis is a central profibrotic pathway after myocardial injury and pressure overload, while innate immune and cytokine pathways regulate leukocyte recruitment, scar formation, and adverse remodeling. Key unresolved questions include which inflammatory signals are reparative versus harmful, when fibrosis is protective versus maladaptive, and whether pathway inhibition improves function without weakening necessary infarct healing or compensatory remodeling.
