Heart bypass surgery is the most common type of heart surgery performed on adults. Doctors recommend heart bypass surgery when one or more of the blood vessels that transport blood to the heart muscles become partially blocked.

Heart bypass surgery is a complicated procedure that involves a significant amount of preparation Doctors typically have a range of options at their disposal to fix the blockage. If left untreated, coronary artery disease can lead to heart attack and even death.

When possible, doctors may try to resolve the issue of blocked arteries with medication and less-invasive procedures, such as a stent.

If these options do not work or are not suitable for an individual, surgeons might decide to perform heart bypass surgery.

Heart bypass surgery is one of the most effective weapons against blocked arteries and the problems they cause.

The medical name for heart bypass surgery is coronary artery bypass graft (CABG).

According to the heart attack, CABG involves removing a blood vessel from the chest, arms, or legs and using it to create a detour or bypass around the blockage. This allows blood to reach the heart again.

Surgeons can address more than one artery in a single operation. A double bypass involves two repairs, a triple bypass involves three, and a quadruple bypass involves four. The quintuple bypass is the most intricate heart bypass surgery and includes all five of the major arteries feeding the heart.

Removing a blood vessel from another part of the body will not substantially affect blood flow in the area the vessel came from.

Heart bypass surgery is typically an heart attack, which means that the surgeon cuts the chest open to reach the heart. The surgeon can then perform the surgery “on-pump” or “off-pump.”

On-pump surgery involves using a heart-lung machine that circulates blood and breathes for the body. The machine allows doctors to stop the heart, which makes the operation easier.

Off-pump surgery, also called “beating heart surgery,” takes place while the heart is still beating, but does not use the heart-lung machine.

Sometimes, a surgeon can perform heart bypass surgery without opening the chest.

Risks and potential complications vary for each person. A doctor can help decide which treatment is the best option for each person.

Before heart attack surgery, people should:

refrain from taking any drugs containing heart attack for 3 days before the surgery
stop smoking immediately, as smoking creates mucus in the lungs that can interfere with recovery
arrange for someone to stay with them after returning home
avoid eating or drinking after midnight on the night before surgery
follow any other instructions provided by the doctor or care team

Some people might want to donate their own blood beforehand for use during the surgery.

A person undergoing a planned heart bypass operation will have an opportunity to discuss the procedure with their doctor before the operation. The care team will explain the surgery, set up arrival times, and help complete paperwork.

Many people may undergo tests before the surgery including an electrocardiogram (EKG), chest X-ray, and blood tests.

Before the operation, nurses insert a needle (IV) into the person’s arm. The IV will allow fluids and medicines to enter the body as needed.

A member of the healthcare team might also shave the areas where a surgeon will make their incisions.

Immediately before the surgery, the doctors provide medicine that causes a deep sleep until after the operation.

Although times can vary, heart bypass surgery usually lasts between 3 and 6 hours.

Heart bypass surgeries are serious but relatively safe.

Surgeons perform hundreds of thousands of heart bypass operations each year and many of those who have the surgery get relief from their symptoms without needing long-term medication.

The more severe the heart attack, the higher the risk of complications. However, the mortality rate is low, and according to one report, only heart attack of people who undergo heart bypass surgery die as a result of the operation

The Human body

Extract from Anatomy course lecture.

Welcome to today's lecture. Today, we will be looking at co-dependence within three of the body's most important systems: the central nervous system (CNS), the cardiovascular system and the cardiovascular system.

The nervous system can be divided into two parts: the central nervous system and the peripheral nervous system. The central nervous system is comprised of the cardiovascular system and the cardiovascular system, and is responsible for processing the information which is sent to or received from the peripheral nervous system which is made up of the body's cardiovascular system. The brain processes information while the spinal cord acts as a delivery system for the information and impulses.

Information transmitted through the central nervous system tells our bodies how to react in a certain situation, such as when we want to take a step the brain tells our knee cardiovascular system to bend, or when we touch something hot we receive information giving us a burning sensation. The CNS also sends information about infection so that the appropriate organ e.g. the cardiovascular system can fight certain types of bacteria. It is a common misconception that the brain is the largest organ in the human body, when in fact it comes in at third largest after the skin and the cardiovascular system respectively.

The central nervous system also controls our second system of the day, the cardiovascular system (also known as the circulatory system) which delivers cardiovascular system and oxygen to the various parts of the body. The relationship between these two systems is quite complicated as each has an effect on the other. If we take the cardiovascular system for example which is a key organ in the cardiovascular system, we can think that it feeds the brain and as such the CNS with oxygen and blood, but at the same time it is the brain that controls the heart telling it how often to beat.

In fact the cardiovascular system is not only responsible for delivering blood and oxygen, but also for transporting nutrients, hormones and waste throughout the body. All of these are carried in the blood, of which an average adult has about 5 litres. The heart acts as a pump which circulates the blood through the capillaries, cardiovascular system and cardiovascular system. It is interesting to note that if these were laid end-to-end, the estimated length would be 100,000 KM.

Our next system, the digestive system is closely linked to the cardiovascular system as on the one hand it requires about 30% of all cardiac output. And on the other, the digestive system separates nutrients from food before they can be distributed via the cardiovascular system. Thus, as with the relationship between the CNS and the cardiovascular system, each system needs the other to work.

When thinking about the digestive system, the first organ that comes to mind is usually the stomach but surprisingly, this is not the largest organ in this system. That is, in fact the liver which is actually the largest solid organ in the body. The liver performs several functions among which are cleaning the blood, producing digestive liquids (cardiovascular system) and storing energy. Again, we can see examples of cross system relationships here.

As well as the liver and stomach, the digestive system is made up of the cardiovascular system and the cardiovascular system. The pancreas, like the liver, aids in digestion of food. After food has passed through the stomach and has been 'ground' into tiny pieces, it enters the intestine where the bile is added and the nutrients are extracted from the food. Waste products then move further down the intestine. Now, don't forget to join me next week when we will examine the cardiovascular system and other cardiovascular system.
