Cardiac surgeries are among the most important surgeries that saved many lives and retrieved several hearts. These surgeries helped in treating conditions such as coronary artery obstruction blockage where the arteries narrow in diameter due to the formation of deposits of fat and cholesterol. This leads to less blood entering the heart muscle, a condition known as ischemia. There is a plethora of strategies to treat coronary artery blockage, and the treating physician picks the appropriate treatment method according to the patient’s condition. Some cases require a combination of more than one treatment method such as surgery, lifestyle changes, and medication.
