What is LAD artery?

The left anterior descending artery (LAD) is the largest coronary artery runs anterior to the interventricular septum in the anterior interventricular groove, extending from the base of the heart to the apex. The LAD gives two sets of branches.

What is LAD in coronary artery disease?

The left anterior descending coronary artery (LAD) is almost always the largest of the 3 epicardial coronary arteries. The LAD typically subtends ≈50% of the left ventricular myocardial mass, or approximately twice as much as either the right or the left circumflex coronary arteries.

What is LAD blockage of heart?

It’s also sometimes referred to as a chronic total obstruction (CTO). The LAD artery carries fresh blood into the heart so that the heart gets the oxygen it needs to pump properly. If it’s blocked, the heart can stop very fast — which is why this type of heart attack is called a “widowmaker.”

What is LAD coronary artery calcification?

Coronary artery calcification is calcium buildup within the walls of the arteries that supply oxygen-rich blood to the heart. This calcium causes the walls to become more hardened, as seen with atherosclerosis.

What is a normal lad score?

A score of 100 to 300 means moderate plaque deposits. It’s associated with a relatively high risk of a heart attack or other heart disease over the next three to five years. A score greater than 300 is a sign of very high to severe disease and heart attack risk.

How long do stents last in LAD?

How long will a stent last? It is permanent. There is just a 2–3 per cent risk of narrowing coming back, and if that happens it is usually within 6–9 months. If it does, it can potentially be treated with another stent.

Is there a relation between glaucoma and NTG?

By contrast, prospective evaluation of patients in the Low-Pressure Glaucoma Treatment Study found no relation between IOP asymmetry and visual field asymmetry. Wide diurnal fluctuations in IOP and nocturnal IOP spikes have also been correlated with NTG .
