Coronary artery bypass surgery - Statistics, "for" and "against"

coronary artery bypass surgery mortality statisticsSince, as has been held the first coronary artery bypass grafting, Mortality statistics has constantly been in the field of view of doctors. It is found that the death after primary CABG is in the range of 1-5%. The bulk of the mortality attributable to acute heart failure. In general, the risk factors are easily divided into two main categories:

  1. Factors preoperative period - the age of the patient, presence of chronic diseases in history, the degree of myocardial ischemia.
  2. Other components - expertise of the operating surgeon, resectable year intervention, the need to support the activities of the heart muscle and so forth.

According to Professor D. Nobel, observation of CABG mortality statistics showed from 1967 to 1980 decreasing. It has been studied more than 58,000 patient records. On the facts of death subsided every year. However, recently there has been the growth indicators. This is due to the fact that the increased age of the operated patients. Above was the degree of severity of the condition is issued for operation patients.

The study showed that the survival rate of people undergoing CABG high. A year later figure is 95% in 5 years - 88% in 15 years - 60%. Studying the results of bypass surgery, it was found that sudden cardiac arrest in the postoperative period - is extremely rare. Mortality statistics in the Bypass includes data on the 10% of heart failure, as a factor provoking death.

Coronary artery bypass surgery - mortality statistics and forecast

Considering for coronary artery bypass grafting, and against, the operation efficiency should be noted. In most cases, the intervention of an experienced surgeon is neutralized angina and increases the degree of portability to the body loads. But the most common manifestation of coronary disease after surgery remains angina. During its restoration after CABG at the time of the return to normal stress it is more likely that coronary blood flow was restored not fully. Second probable reason is early graft occlusion. Similar changes in the later period is called:

  • stenosis;
  • exacerbation of atherosclerosis in coronary arteries;
  • occlusion of shunts due to thrombosis or embolism;
  • combinatorial combination of the above characteristics.

Reliable indicator of the results of CABG is the patient's state of health, which is difficult to express in measured units. Argue about the good condition of the patient may be on the general health, absence of dyspnea, angina. Speaking about the effectiveness of the procedure no complications.

If performed bypass surgery, statistics show that 5 years after the operation state of health of the former surgical patients gradually deteriorates with the appearance of angina. However, the data demonstrate that the negative state within 5 years absent in 75-80% of people undergoing coronary artery bypass grafting in 10 years - at 65-70%. 15 years after bypass surgery mortality statistics show an interesting picture - up to 20% of patients are alive and are not subject to attacks of angina.

Coronary artery bypass surgery - statistics of changes

When you drill results demonstrate the change CABG patient. As a result, normalized blood flow to the myocardium:

  • neutralized stenokardicheskie attacks;
  • observed improvement of physical condition;
  • reduced risk of myocardial infarction;
  • improved performance, increases the amount of physical activity;
  • pharmacological care is minimized.

Most importantly - increased life expectancy, reduced the likelihood of sudden cardiac arrest after undergoing surgery. Testimonials show improvements in most cases. Doctors conducting coronary artery bypass surgery, give it a favorable prognosis. Specialists return the patient to a normal life, makes available to seriously ill ordinary human happiness.

CABG statistics show neutralizing frightening health problems in 80% of cases. In 85% of the time there is no re-occlusion of vessels. In many patients, there are concerns about the short duration of life after surgery. The unequivocal answer to this question does not exist. Much depends on the co-factors - lifestyle, age-related parameters, addictions. The average service life of the shunt is determined by a 10-year period, it can be increased in young patients. At the end of the period it is recommended to perform repeated CABG.

The efficiency of the operation proved today by the world scientific community, however, is not always coronary artery bypass surgery has a favorable prognosis. Like any operable one intervention procedure gives complications. In clinical practice, noted: heart attack, stroke, infection of the cut vein thrombosis. Often the patients themselves to blame for the lack of improvements. This is due to unfounded fears for his life, fear of death, stress and "looping" on the disease. Patients are encouraged to rehabilitation recovery with a psychologist. To reduce the risk of adverse effects should be addressed to the professional doctors are highly skilled and successful practice operations.

It decides whether the operation the patient. For informed choice requires a comprehensive assessment of all risks. Doctors warn about them at the stage of examination, make recommendations for further treatment. CABG mortality statistics has minimal value. Today the operation is carried out, even in difficult cases, and in the elderly. This is a chance to extend the life and improve their own health.
