Bypass surgery also is known as Coronary Artery Bypass Surgery or colloquially heart bypass is a surgical procedure to improves blood flow to the heart.

Coronary Heart Disease & Symptoms

Coronary heart disease is a narrowing of the blood vessels that supply blood and oxygen to the heart. The most common symptom of coronary artery disease is angina or chest pain. Angina can be described as a discomfort, heaviness, pressure, aching, burning, fullness, squeezing, or painful feeling in your chest. It can be mistaken for indigestion or heartburn. Angina may also be felt in the shoulders, arms, neck, throat, jaw, or back. Some other symptoms of coronary artery disease include:

  • Sweating
  • A faster heartbeat
  • Shortness of breath
  • Weakness or dizziness
  • Palpitations (Irregular Heartbeats)

Risk factors for Coronary Heart Disease

  • Smoking
  • Diabetes
  • Family history
  • High cholesterol
  • High blood pressure
  • Peripheral artery disease

Diagnosis of Coronary Artery Disease

An investigation like an electrocardiogram, stress tests, ultrasound imaging of the heart muscle, coronary angiography, high-speed CT scan is done to diagnose this disease.

How does Coronary Artery Disease Develop?

PTCA is a treatment of coronary artery disease. In angioplasty, a balloon-tipped catheter is inserted through the skin into a blood vessel and to the clogged portion of the artery. There it is threaded into the blockage and inflated, compressing the plaque (buildup of fat and cholesterol) against the arterial walls. Frequent postoperative reclogging (narrowing of blood vessels) of the treated area has led to the use of stent (sometimes coated with a drug that inhibits narrowing of a blood vessel) designed to hold the plaque back.

What to do after the Procedure

  • Coronary artery disease occurs when plaque (accumulated by fats and cholesterols) builds up in the walls of the arteries.
  • When a blood clot (thrombus) forms on top of this plaque, the artery becomes completely blocked causing a heart attack.
  • The heart muscle becomes starved of oxygen, and patients often experience chest pain when the blood oxygen supply cannot keep up with demand.
  • When coronary arteries narrow more than 50 to 70%, the blood supply beyond the blockage becomes inadequate to meet the increased Oxygen demand.
