Which condition involves formation of scar tissue in heart muscle due to oxygen deprivation?

The condition that involves the formation of scar tissue in the heart muscle due to oxygen deprivation is indeed infarction. More specifically, this refers to myocardial infarction, commonly known as a heart attack. When blood flow to a part of the heart is obstructed, often by a clot or plaque, the heart muscle cells in that area become deprived of oxygen and nutrients. As a result, these cells can die and are eventually replaced by scar tissue during the healing process. This scar tissue does not contract or function like healthy heart muscle, which can lead to complications such as heart failure or arrhythmias.

The other options, while relevant to cardiovascular health, do not describe the scar tissue formation due to oxygen deprivation. Thrombosis refers to the formation of a blood clot within a blood vessel and does not inherently involve the scar tissue formation process. Arrhythmia pertains to irregular heart rhythms and is not directly related to tissue damage or scarring. Carditis refers to inflammation of the heart and might cause damage, but it does not specifically indicate the scar tissue formation primarily related to oxygen deprivation as seen in infarction.
