1. Heart attack

Heart attack, or myocardial infarction, usually tops the list of cardiovascular diseases in the world. A heart attack in the world happens about every 4 seconds.

A heart attack occurs, when the heart muscle is deprived of oxygen, necessary for work. This happens because, that blood flow, delivering that oxygen, was significantly reduced or completely stopped. This is due to atherosclerosis or slow plaque buildup, which include fat, cholesterol and other substances, in the coronary arteries. Blood clots may form around the plaques, that slow or block blood flow and cause a heart attack.

2. Stroke

Stroke is considered a heart disease, since this condition is associated with impaired blood flow. However, a stroke occurs due to problems with blood flow to the brain., not to the heart. Ischemic strokes up 87 percent of all strokes and occur due to blockage of a blood vessel, delivering blood and oxygen to the brain. Without blood and oxygen, parts of the brain can be damaged or die., if they are not treated quickly. Hemorrhagic strokes may have various causes besides blockage, such as vascular malformations or abnormal growth of blood vessels in the brain.

3. Heart failure

Heart failure, also called congestive heart failure, arises due to, that the heart is not pumping blood properly. It does not mean, that the heart stops beating completely, as the name suggests. The heart continues to pump blood, but not fast enough, for the body to continue to function normally. Fatigue and shortness of breath, which may result from untreated heart failure, can greatly interfere with daily activities, such as walking or climbing stairs.

4. Arrhythmia

Cardiac arrhythmia any abnormal heart rhythm: too slow, too fast, uneven rhythm or tempo. Without the correct rhythm, the heart does not work as efficiently. The heart may not be able to pump enough blood to deliver oxygen and nutrients to other organs..

5. Complications of the heart valve

Like arrhythmias, heart valve complications may include many different anomalies. Stenosis means, that the valves in the heart don't open enough, so that blood can flow normally. Regurgitation occurs, when the heart valves don't close properly, which causes bleeding. Like the arteries in your heart, heart valves also need to work properly, to prevent complications, that will negatively affect your life.
