What is proximal and Distal LAD Blockage and Treatment l हार्ट ब्लॉकेज और ईलाज
Your left anterior descending (LAD) artery is one of two branches of your left main coronary artery. Anterior means the artery supplies blood to the front portion of your heart. It's the biggest supplier of oxygenated blood to your heart’s lower left pumping chamber or ventricle. It also supplies blood to the septum, the muscular tissue that separates the heart walls.

Your healthcare provider may also refer to this blood vessel as the anterior interventricular branch. A complete blockage of your left anterior descending artery can cause a heart attack, commonly known as a widowmaker. This type of heart attack is often fatal.

LAD is short for left anterior descending coronary artery, an important branch of left main coronary artery, which supplies oxygenated blood to a major portion of the left ventricle. The vessel regions are divided into proximal, mid and distal. Proximal means the initial region near the origin. Distal means the region near the end. Mid naturally indicates the region in between. Distal disease means that narrowing of the vessel is near its terminal region. Hence distal LAD disease is likely to be less dangerous than a proximal LAD disease. Technically, proximal LAD is the region from the origin to the first branch, which could be either a septal (supplying blood to the interventricular septum, separating the right and left ventricles) or a diagonal (supplying blood to the left side wall of the left ventricle). Region between the first branch and the second diagonal branch is called mid LAD. Region beyond the second diagonal branch is known as distal LAD. Distal LAD disease is usually treated medically while proximal and mid LAD disease, if critical, can be treated by angioplasty (balloon inflation within the vessel using special catheters) or bypass grafting (CABG or coronary artery bypass grafting operation).

Myocardium Is middle layer of heart
myocarditis means inflammation of myocardium
most common cause is viral infection


heart attack occur when blood supply of heart muscle is blocked and heart doesn't get oxygen and nutrition.

Permanent pacemaker is electronic device which includes battery and leads which is used for increasing heart beat in patient with complete heart block or AV conduction abnormalities.

Temporary pacemaker is device with a lead and battery which is used in bradycardia and low heart beat .
lead put in right ventricle and stimulate the heart so heart beat is increased.

Angiography is best test for coronary artery blockages diagnosis.

echo is good to identify heart attack, fir this see two things in echo report
1. RWMA or hypokinesia
2. Ejection fraction

in heart attack rwma will be there and ejection fraction will less than normal

4 test for heart attack
1.ecg
2 Troponin test
3 Echocardiography
4 Angiography
