Heart failure is a chronic and progressive condition in which the heart is unable to pump blood effectively, leading to inadequate blood flow to meet the body's needs. This can result from various underlying conditions, including coronary artery disease, hypertension, and cardiomyopathy. Patients often experience symptoms such as shortness of breath, fatigue, and fluid retention, which can significantly impact their quality of life. Advances in heart failure medicine have introduced a wide range of treatment options, including lifestyle modifications, medications such as ACE inhibitors, beta-blockers, and diuretics, as well as innovative therapies like device implantation and heart transplantation. Ongoing research is focused on improving existing treatments and developing new therapies to enhance patient outcomes and manage this complex condition more effectively.
