The common name for the medical field that studies and treats conditions of the heart is cardiology. Cardiologists specialize in diagnosing, treating, and preventing diseases related to the heart and blood vessels. This field covers a wide range of conditions, including coronary artery disease, arrhythmias, heart failure, and congenital heart defects. Cardiologists perform various diagnostic tests, such as electrocardiograms (ECGs), echocardiograms, and stress tests, to evaluate heart health. They may also manage treatment plans involving medications, lifestyle changes, and, in some cases, surgical interventions. The role of cardiology is crucial, given the high prevalence of heart-related illnesses globally.
