As the name implies, heart bypass is to take the patient's own blood vessels (such as internal thoracic artery and great saphenous vein of lower limbs). ) 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". ?
Indications of emergency cardiac bypass surgery
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 cardiac 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. Long-term or even life-long medication reduces 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.
I hope the above reply is helpful to you.
