Bypass surgery refers to a surgical procedure that helps in diverting the blood flow around a blocked or partially blocked artery of the heart. It is done to create a new pathway to the heart and improving the flow of blood to the heart muscle. During this surgery, a healthy, well-functioning blood vessel is taken from the arm, chest or leg and then connected to the other arteries in the heart so that the blood can bypass the blocked or the diseased area.
Problems such as shortness of breath and chest pain, due to poor flow of blood tend to improve after a bypass surgery. It may also improve the heart function and reduce the risk of a heart disease.

Individuals more often than not begin to eat and move around not long after the specialist has evacuated the breathing tube carefully. Normal post-surgery meds ordinarily incorporate medications called platelet inhibitors, which help anticipate blood clusters.
Life expectancy after surgery has not. 90% of a group of 1,324 patients worked on somewhere in the range of 1972 and 1984 endure five years after surgery, as indicated by one investigation, and 74 percent endure 10 years. That number has remained generally stable from that point onward. In any case, more seasoned and more broken down patients are getting sidestep medical procedure nowadays, which may influence survival rates.

Enhanced external counterpulsation (EECP) is known as an outpatient procedure which can be performed as an alternative to heart bypass surgery, according to multiple studies. In 2002, it was approved by the Food and Drug Administration (FDA) for use in people with congestive heart failure (CHF).
EECP involves compressing blood vessels in the lower limbs. This increases blood flow to the heart and extra blood is delivered to the heart with every heartbeat. Over time, some blood vessels may develop extra “branches” that will deliver blood to the heart, becoming a sort of natural bypass. EECP is administered daily for a period of one to two hours over the course of seven weeks.
