Cardiology is the branch of medicine that deals with disorders of the heart and blood vessels. It encompasses a wide range of conditions, including coronary artery disease, heart failure, and arrhythmias. Cardiologists are specialized doctors who diagnose and treat these conditions, often using advanced technology and procedures. In addition to treating heart diseases, cardiology also focuses on preventive measures to maintain heart health. This includes lifestyle changes, such as diet and exercise, as well as medications to manage risk factors like high blood pressure and cholesterol. Regular check-ups with a cardiologist can help individuals stay informed about their heart health and prevent serious complications.
