Cardiac fibrosis is a pathological condition characterized by the excessive accumulation of collagen fibers in the heart tissue, leading to increased stiffness and impaired function of the heart. This condition often results from prolonged or chronic cardiovascular diseases, such as hypertension or chronic inflammation. As the collagen deposits replace normal heart tissue, the heart's ability to pump blood efficiently is compromised, potentially leading to heart failure. Cardiac fibrosis is a significant concern in the field of cardiology, as it represents a key factor in the progression of various heart disorders. Understanding the molecular mechanisms underlying cardiac fibrosis is crucial for developing targeted therapeutic interventions aimed at preventing or reversing this detrimental process and preserving heart function. Ongoing research in this area seeks to unravel the complexities of cardiac fibrosis, paving the way for innovative treatments to mitigate its impact on cardiovascular health.
