So we will learn about how heart attack is cause and what are the symptoms of heart attack or heart failure.so lets find out all the heart related issues detail.


What are the Functions and How it Works?

The heart pumps blood through the body carrying oxygen and nutrients to all cells in the body so they can survive and do their jobs. The blood also carries waste products from the cells to the organs that get rid of a waste such as your kidneys, your heart is a double pump.

  • The right side pumps blood to your lungs where the blood picks up oxygen and then is returned to the left side of the heart.
  • The left ventricle then pumps blood to your body through the large artery called the aorta. As the blood circulates oxygen is moved from your blood to the cells throughout your body.

Blood that do not has oxygen returns to the right side of the heart through your veins. This process occurs with each heartbeat. The heart itself needs a constant supply of oxygen. The blood richest oxygen is carried through the arteries. These arteries are found on the surface of the heart.

What are the Causes of Heart Attack and Failure?

There are two main arteries main arteries known as coronary arteries


  1. The left main coronary artery
  2. The right coronary artery

These two arteries then divide into many smaller branches that go into the heart muscle. Any coronary artery abnormality can cause reduced flow of oxygen and nutrients to the heart, which may lead to a heart attack and possibly death. This can cause the artery to narrow or become blocked a form of atherosclerosis. This is the most common cause of heart disease. Coronary heart disease also known as coronary artery disease or COPD is a hardening of the arteries caused by the accumulation of fatty deposits, which is often called Plaque. This plaque buildup occurs a lot of the innermost layer of the coronary arteries.

The fatty deposits may produce in childhood and continue to thicken and enlarge during life. As the plaque builds up the artery narrows and blood flow gets low to the heart muscle. When blood flow is decreased you have reduced flow of oxygen and nutrients to the heart. When the narrowing is severe the tissues are at risk for not getting enough oxygen and nutrients. We now know that these plaques that develop can rupture or break open the body then tries to repair the site and forms a blood clot which can block blood flow completely.If this happens and blood flow is not restored the tissues may die which is considered a heart attack.




Our bodies often warn us that the heart is not getting enough oxygen and nutrients. Signs of coronary heart disease will depend on the seriousness of the disease. Some persons with CHD have no symptoms. Some have stages of mild chest pain or angina and some have more chest pain. When symptoms are present, each person may feels them differently. Symptoms of coronary artery disease may have heaviness, tightness, pressure and pain in the chest behind the breastbone pain radiating in the arms, shoulders, jaw, neck, and or back. Shortness of breath, weakness and fatigue, nausea or vomiting may occur as well being aware of your risk factors is very important and controlling your risk of having a heart attack in the future. Risk factors include high LDL cholesterol also known as bad cholesterol high triglyceride levels and low HDL cholesterol which is your good cholesterol high blood pressure also known as hypertension.

It’s important to follow a diet low in saturated fat and high in fiber fruits and vegetables. Make sure your blood sugar is monitored regularly if you have diabetes and treat elevated blood sugar to recommended goals controlling risk factors is the key to preventing illness and death from COPD.Make sure you talk to your doctor if you have any of these risk factors. There are many ways to address and treat these risk factors. Each person should have an individual plan to care for his or her risks.
