Coronary heart disease (CHD) is a condition that affects the heart's blood vessels. Synonyms for CHD include coronary artery disease, ischemic heart disease, atherosclerotic heart disease, and coronary heart syndrome. These terms refer to the same illness that causes blockages in the coronary arteries, leading to chest pain, shortness of breath, and other symptoms. While there are medical treatments for CHD, lifestyle changes such as diet and exercise can also be effective in managing the condition. It is important to recognize the various synonyms for CHD to ensure that patients understand their diagnosis and receive accurate information about their health.
