Heart Bypass Surgery

Currently in technologically sophisticated hospitals, the success rate of heart bypass surgery is about 98%. All major and minor surgeries have risks, and it is a question of whether the benefits outweigh the risks or the disadvantages outweigh the benefits of not having heart bypass surgery in this case, which is even more risky. Here is a detailed description of heart bypass surgery, take a look, it should help.

Cardiac bypass surgery

Bypass surgery, as the name suggests, is to take the patient's own blood vessels (such as the internal thoracic artery, the saphenous vein in the lower limbs, etc.) or vascular substitutes, the distal end of the stenotic coronary artery and the aorta are connected to the narrowed part of the coronary artery, so that the blood is spared the narrowed part, to reach the ischemic parts of the ischemic parts of the heart muscle to improve the blood supply, which will help alleviate the symptoms of angina pectoris, improve the heart function and improve the patient's quality of life and prolong life expectancy. The procedure, known as coronary artery bypass grafting, creates a smooth path between the root of the aorta, which is full of arterial blood, and the ischemic heart muscle, and is therefore imaginatively referred to as "bridging the gap" between the heart and the arteries, commonly known as "bypass grafting".

Coronary heart disease is caused by atherosclerosis of the coronary arteries, resulting in narrowing or blockage of the lumen, leading to myocardial ischemia, hypoxia caused by heart disease, including chronic myocardial ischemia syndrome (stable angina, etc.) and acute coronary syndrome (ACS). As a group of clinical syndromes caused by acute myocardial ischemia, ACS is divided into unstable angina (UA), non-ST-segment elevation myocardial infarction (NSTEMI) and ST-segment elevation myocardial infarction (STEMI). Currently, there are two major approaches to the medical treatment of ACS in the clinic, namely, coronary stenting (PCI), cardiac bypass grafting (CABG), and antiplatelet, anticoagulant, and thrombolytic medications.

Now, coronary heart disease is the number one killer of human health, coronary heart disease mortality accounts for 10% to 20% of all heart disease deaths. Happily, at present, the domestic and foreign medical treatment of coronary heart disease is more and more advanced, more and more clever, high-tech methods to make the world many patients with coronary heart disease to regain a new life. Cardiac stent surgery, cardiac bypass and other technologies flourish very quickly, extracorporeal circulation technology has also made great strides in the advanced, cardiac arrest, cardiac non-stop bypass, as well as minimally invasive surgery has been commonly practiced in the clinical and less traumatic, faster recovery. However, some coronary heart patients do not know whether they should be operated? Some patients do not know whether they should choose coronary stent surgery or heart bypass surgery?

The indications for coronary artery disease surgery are given below

Indications for cardiac stenting intervention (PCI) (1-2 stenoses and easy to put a stent in)

1. Acute myocardial infarction

2. Angina pectoris (stable and unstable) medication is ineffective, and coronary artery angiography suggests that the vessel has a stenosis of more than 75%. .

Indications for emergency coronary artery bypass grafting (CABG)

1. Left main stem lesion

2. Left main stem plus three branches lesion

3. Acute myocardial infarction within 6-8 hours, vascular anatomy is suitable to receive coronary artery bypass grafting

4. Acute myocardial infarction with complications such as papillary muscle rupture and ventricular free wall rupture

< p>5. Acute myocardial infarction with intractable arrhythmia, ineffective active medical treatment, and vascular anatomy suitable for receiving coronary artery bypass grafting

6. Diagnostic or medical treatment for PCI with entrapment, cardiac or vascular dissection, pericardial tamponade, etc.

Indications for Elective Coronary Artery Bypass Grafting (cardiac bypass grafting surgery)

1. Left main stem lesion

2. Most two- and three-branch vasculopathies involving the proximal left anterior descending end

3. Three-branch vasculopathies with left cardiac insufficiency

4. Combinations of significant valvulopathies, ventricular wall aneurysms, and other pathologies

5. Combinations of multibranch vasculopathies with diabetes mellitus

6. Chronic complete occlusion of some one- and two-branch lesions

Reminders to the inoperative population:

1. p>

1. Should take medication for a long time or even for life to reduce the probability of reoccurrence.

2. Weight control, moderate exercise, smoking cessation and alcohol restriction, lowering blood pressure and fat.

3. Regularly review the electrocardiogram, blood lipids, etc., and seek immediate medical attention in case of discomfort.
