Cardiology is a branch of medicine focused on the study, diagnosis, and treatment of disorders affecting the heart and blood vessels. This field plays a critical role in addressing conditions like coronary artery disease, heart failure, arrhythmias, and congenital heart defects. Cardiologists use advanced diagnostic tools, such as echocardiograms, electrocardiograms (ECGs), and cardiac catheterization, to assess heart health and develop tailored treatment plans. With heart disease being a leading cause of death worldwide, cardiology remains at the forefront of medical innovation, emphasizing preventive care, lifestyle modifications, and cutting-edge therapies to improve cardiovascular health and patient outcomes.
