Cardiac Sciences

Cardiac sciences, or cardiology, is a branch of medicine that deals with illnesses pertaining to heart and circulatory system. These diseases, known as cardiovascular diseases, account for the highest number of deaths in the world. According to the World Health Organization 31 per cent of the global deaths happen due to cardiovascular diseases.

Types of cardiovascular diseases

Various types of cardiovascular diseases are heart attack,

Arrhythmia:Also known as dysrhythmia, is a disease that means your heartbeats run out of rhythm. Arrhythmia produces uneven heartbeats.

Heart failure:A heart failure means your heart is not pumping like usual. It leads to breathing shortness.

Heart valve disease:There are three types of heart valve diseases. A Mitral valve prolapse means the valve that exists between the left-upper and left-lower chambers don’t close properly; an Aortic Stenosismeans the narrowing of your aortic valve; and a Mitral valve insufficiency means your mitral valve doesn’t close as it should.

Coronary artery disease:Also known as CAD, it means hardening of arteries.

Pericardial disease:It is a rare disease. It makes the linings around your heart swell up.

Cardiomyopathy:It means you will have an enlarged heart, failing to pump blood as usual.

Aorta disease:It is caused by a widening or a tear in the aorta, which is the largest artery of the body.

Marfan syndrome:It is a disease that affects the body’s connective tissues.

Congenital heart disease: A disease that develops before birth. It means defect in the structure of heart or blood vessels.

Vascular diseases:It means diseases of the circulatory system that affect the arteries and blood flow to brain.
