Cardiac disease also called Heart and blood vessel disease — includes numerous problems, many of which are related to a process called atherosclerosis. Atherosclerosis is a condition that develops when a substance called plaque builds up in the walls of the arteries. This buildup narrows the arteries, making it harder for blood to flow through. If a blood clot forms, it can stop the blood flow. This can cause a heart attack or stroke.

heart attack occurs when the blood flow to a part of the heart is blocked by a blood clot. If this clot cuts off the blood flow completely, the part of the heart muscle supplied by that artery begins to die.

Heart failure: This doesn't mean that the heart stops beating.means the heart isn't pumping blood as well as it should. The heart keeps working, but the body's need for blood and oxygen isn't being met. 

Arrhythmia: This is an abnormal rhythm of the heart. There are various types of arrhythmias. The heart can beat too slow, too fast or irregularly. Bradycardia is when the heart rate is less than 60 beats per minute. Tachycardia is when the heart rate is more than 100 beats per minute.

Heart valve problems: When heart valves don't open enough to allow the blood to flow through as it should, it's called stenosis. When the heart valves don't close properly and allow blood to leak through, it's called regurgitation. 

Preventing heart disease (and all cardiovascular diseases) means making smart choices now that will pay off the rest of your life. Lack of exercise, a poor diet and other unhealthy habits can take their toll over the years. Anyone at any age can benefit from simple steps to keep their heart healthy during each decade of life.

What You Can Do to Prevent Heart Disease (For All Age Groups):-

Choose a healthy eating plan. The food you eat can decrease your risk of heart disease and stroke. As part of a healthy diet, eat plenty of fruits and vegetables,fiber-rich grains, fish, nuts and seeds and try eating some meals without meat. Select lower fat dairy products and poultry.

Be physically active. You can slowly work up to at least 2½ hours of some aerobic physical activity, e.g. brisk walking, jogging, running playing sports, etc. Children should get at least 1 hour of activity every day.
