This text will discuss on a surgery named coronary artery bypassgraft, and several complication that may arise due to this surgery. Thisoperation is considered as one of the most popular in America and more than400,000 people underwent this surgery during the 2004. When a person has ablocked arteries or their narrowing in the heart this surgery is performed. Ithelps by making the blood flow pass more easily and when this is doneheartmuscles will have the nutrients and oxygen they need. Coronary artery condition is created whenatherosclerotic plaque gathers in the blood supplying artery wall. Activitieslike smoking and conditions such as diabetes, cholesterol and blood pressureproblem help with the gathering of the plaque. This gathering is also verycommon among old people with some heart problems in the family, and cholesterol isthe main component of this plaque. When narrowing occurs the usual suspect isthe atherosclerosis process. When the blood doesn't reach the final destination along with other important things, oxygen in not supplied either. If thenarrowing is considerate, 50-70%, this problem can be very grave and serious.
One quarter of persons experiencing this problem do not developchest pain, but others do. Chest pain happens when oxygen is not delivered.Complete blockage of the artery can occur if a blood clot is made on theplaque. There is a risk of heart attack for the individuals with angina, whichalso depends on the narrowing because the extreme narrowing produce angina at restand accelerated angina. There is also the possibility of unstable anginaproduction. When talking about the recovery period, seven toten days will take for a patient to leave the hospital after the surgery.Support stocking will be needed for the first five to six weeks. Patients willhave to avoid lifting heavy items and driving the car but after six weeks theycan return to their work. Patient will have to attend a program called cardiacrehabilitation program which lasts for 12 weeks and includes some exercises,like stress exercises. Also a patient will have to eliminate smoking, lowerblood cholesterol maintain blood pressure and diabetes, and decrease dietaryfat and weight.
Risks include heart attack (5 to 10 %), death (3to 4 %), bleeding (5 %) and stroke (1 to 2 %, especially in old people) but lungcomplications and chest infection are also possible problems after this surgery. Ifa person has more than 70 years, diabetes, chronic kidney failure and lungdisease, problem with left main coronary artery and poor heart muscle function,that person has the greatest chances for developing coronary artery disease.Women are more affected by this disease and they are affected approximately tenyears before men.
