Cardiovascular problems or diseases (CVDs) are the conditions that affect the structures and function of the heart.

CVDs usually include a wide spectrum of diseases, such as:

• Angina, pain in the chest
• Arrhythmia, irregular heartbeat, or heart rhythm
• Congenital heart diseases
• Coronary artery disease, which affects the arteries that supply oxygen-rich blood to the heart muscle
• Heart attack
• Heart failure, unusual contraction, and relaxation of the the heart
• Dilated cardiomyopathy
• Hypertrophic cardiomyopathy
• Mitral regurgitation
• Mitral valve prolapse, in which part of the mitral valve grows into the left atrium of the heart leading to mitral regurgitation
• Rheumatic heart disease is an inflammation of the heart
• Pulmonary stenosis, in which narrowing of the artery results in an impaired blood flow from the right ventricle to the pulmonary artery
• A narrowing of the heart valve results in blockage to the blood flow leaving the heart, called Aortic stenosis
• Common radiation also induces heart diseases
