## Step 1The problem is about diagnosing an acute myocardial infarction (MI), also known as a heart attack. The most accurate tests for diagnosing MI are cardiac troponin (cTnT) and CK-MB. These tests are highly specific for myocardial injury and are considered the gold standard for diagnosing MI.## Step 2AST (Aspartate Aminotransferase) and CK (Creatine Kinase) are also used to diagnose MI, but they are less specific than cTnT and CK-MB. They can also be elevated in other conditions, such as liver disease or muscle damage, which can lead to false positives.## Step 3LD (Lactic Acid Dehydrogenase) is not typically used in the diagnosis of MI. It can be elevated in a variety of conditions, including liver disease, anemia, and kidney disease, which can lead to false positives.## Step 4Given the options, the combination of cTnT and CK-MB (Option C) would be the best choice for diagnosing the sudden onset of MI. This is because these tests are highly specific for myocardial injury and are considered the gold standard for diagnosing MI.
