Cardiology is the branch of medicine dedicated to the study, diagnosis, and treatment of disorders related to the heart and circulatory system. Cardiologists, specialized physicians in this field, focus on preventing and managing conditions such as heart disease, heart failure, and arrhythmias. They employ various diagnostic tools, including electrocardiograms (ECGs) and imaging techniques, to assess heart health. Treatment options range from lifestyle interventions and medication to invasive procedures like angioplasty or coronary bypass surgery. Cardiology plays a crucial role in promoting cardiovascular health and addressing conditions that pose significant threats to the well-being of individuals.
