2. Left anterior descending artery - Wikipedia

   en.wikipedia.org/wiki/Left_anterior_descending...

   Even a small amount of plaque in this area can (for a variety of poorly understood reasons) rupture and cause death; bypassing chronic blockages or trying to open them up with angioplasty does not prevent heart attack but it can restore blood flow in case of a sudden blockage or heart attack and if performed within a rapid time period can ...

3. Coronary occlusion - Wikipedia

   en.wikipedia.org/wiki/Coronary_occlusion

   A new heart disease diagnosis approach has led to a 99.1% accuracy in diagnosing heart disease. [18] This new diagnosis approach uses CT-scan imagery to focus on coronary artery diseases and blockages in contrast to angiography. [18] Further research directions in preventing and treating coronary artery disease include: [19]

4. Coronary ischemia - Wikipedia

   en.wikipedia.org/wiki/Coronary_ischemia

   Reduced blood flow to the heart associated with coronary ischemia can result in inadequate oxygen supply to the heart muscle. [6] When oxygen supply to the heart is unable to keep up with oxygen demand from the muscle, the result is the characteristic symptoms of coronary ischemia, the most common of which is chest pain. [6]

5. Infarction - Wikipedia

   en.wikipedia.org/wiki/Infarction

   Infarction occurs as a result of prolonged ischemia, which is the insufficient supply of oxygen and nutrition to an area of tissue due to a disruption in blood supply.The blood vessel supplying the affected area of tissue may be blocked due to an obstruction in the vessel (e.g., an arterial embolus, thrombus, or atherosclerotic plaque), compressed by something outside of the vessel causing it ...

6. Coronary arteries - Wikipedia

   en.wikipedia.org/wiki/Coronary_arteries

   Coronary artery disease (CAD) or ischemic heart disease are the terms used to describe narrowing of the coronary arteries. [8] As the disease progresses, plaque buildup can partially block blood flow to the heart muscle. Without enough blood supply , the heart is unable to work properly, especially under increased stress.

7. Left bundle branch block - Wikipedia

   en.wikipedia.org/wiki/Left_bundle_branch_block

   Left bundle branch block (LBBB) is a conduction abnormality in the heart that can be seen on an electrocardiogram (ECG). [1] In this condition, activation of the left ventricle of the heart is delayed, which causes the left ventricle to contract later than the right ventricle .
