What's the difference between heart bypass and stent?

What's the difference between heart bypass and stent? The differences between cardiac stents and cardiac bypass are described in detail as follows:

Percutaneous coronary intervention

Cardiac stent implantation is a new technique for treating coronary heart disease in recent 20 years. Simply put, the process of cardiac stent surgery is to puncture the blood vessel, make the catheter advance in the blood vessel and reach the opening of the coronary artery, use a special delivery system to transport the stent to the place where it needs to be placed, place and take out the catheter, and end the operation.

Heart bypass surgery

As the name implies, bypass surgery is to take the patient's own blood vessels (such as internal thoracic artery, great saphenous vein of lower limbs, etc.). ) or vascular substitutes connect the distal end of the narrow coronary artery with the aorta, so that the blood bypasses the narrow part and reaches the ischemic part, improving the blood supply to the myocardium, thereby achieving the purposes of relieving angina symptoms, improving cardiac function, improving the quality of life of patients and prolonging life. This operation is called coronary artery bypass grafting, which establishes a smooth path between the aortic root filled with arterial blood and ischemic myocardium. Therefore, some people call it "bridging" in their hearts, commonly known as "bridging". ?

At present, coronary heart disease is the number one killer threatening human health, and the mortality rate of coronary heart disease accounts for 10%~20% of all heart disease deaths. It is gratifying that at present, the methods of treating coronary heart disease at home and abroad are more and more advanced and precise, and high-tech methods have revived many patients with coronary heart disease all over the world. Techniques such as cardiac stent surgery and bypass surgery have developed rapidly, and cardiopulmonary bypass technology has also made great progress. Cardiac arrest, beating heart bypass surgery and minimally invasive surgery are widely used in clinic because of their minimal trauma and quick recovery. But some people with coronary heart disease don't know if they should have surgery. Some patients don't know whether to choose coronary stent surgery or heart bypass surgery.

The indications for coronary heart disease surgery are as follows.

Indications of percutaneous coronary intervention (PCI) (1-2 is narrow and easy to place stents).

1. Acute myocardial infarction

2. Angina pectoris (stable and unstable) is not effective, and coronary angiography shows that the vascular stenosis is more than 75%.

Indications of emergency coronary artery bypass grafting

1. Left main lesion

2. Lesions in the left trunk and three branches

3. Within 6~8 hours of acute myocardial infarction, the vascular anatomy is suitable for coronary artery bypass grafting.

4. Complications such as papillary muscle rupture and ventricular free wall rupture occurred in acute myocardial infarction.

5. Intractable arrhythmia occurred in acute myocardial infarction, and active medical treatment was ineffective. Vascular anatomy is suitable for coronary artery bypass grafting.

6. Anatomy, heart or blood vessel rupture, pericardial tamponade, etc. It happened at 6. PCI diagnosis or drug therapy.

Indications of selective coronary artery bypass grafting (heart bypass surgery)

1. Left main lesion

2. Most bi-vascular and tri-vascular diseases involve the proximal left anterior descending branch.

3. Three-vessel disease of left ventricular dysfunction

4. Combined with meaningful valvular disease, ventricular aneurysm and other lesions.

5. Diabetes complicated with multi-vessel disease.

6. Partial single-branch and double-branch lesions of chronic total occlusion

Remind people who have not operated:

1. Take the medicine for a long time or even for life to reduce the recurrence probability.

2. Restrain weight, exercise moderately, quit smoking and limit alcohol, and lower blood pressure and blood lipid.

3. Check ECG and blood lipid regularly, and seek medical advice immediately if you feel unwell.
