Question

Imbalance between supply and demand of oxygen to myocardium results in

• A. Congestive Heart Failure
• B. Myocardial Infarction
• C. Arrythmia
• D. Atherosclerosis

Answer 1

Answer:

B. Myocardial Infarction

• Myocardial Infarction - Commonly known as a heart attack, this occurs when an imbalance between myocardial oxygen supply and demand causes severe ischemia, leading to necrosis (cell death) of the heart muscle.

• Congestive Heart Failure - A condition where the heart is unable to pump sufficient blood to meet the metabolic demands of the body's tissues.

• Arrhythmia- An abnormality or irregular rhythm in the electrical conduction system of the heart.

• Atherosclerosis -The buildup of fatty deposits, cholesterol, and cellular debris (plaques) inside the arterial walls, which leads to narrowing of the arteries—often the underlying cause of myocardial infarction.
