Final answer:
The proper assessment sequence for suspected cardiovascular issues is blood tests, followed by criteria application, and then imaging with TTE and TEE option (b) if needed. Blood tests typically check for creatine kinase MB and cardiac troponin, while ECGs can show changes indicative of a myocardial infarction.
Step-by-step explanation:
In the context of medical diagnosis for a patient with suspected cardiovascular issues, the correct sequence for assessing the patient is B) Blood Cx, Major and Minor criteria, TTE, and TEE. Typically, a diagnostic workup begins with a blood culture (Blood Cx) to identify any infection, followed by the application of Major and Minor criteria to confirm the diagnosis of conditions such as infective endocarditis.
Subsequently, non-invasive imaging like transthoracic echocardiography (TTE) is performed, and if needed, transesophageal echocardiography (TEE) can provide a more detailed view of the heart's structure and function.
For instance, in the diagnosis of myocardial infarction (MI), common blood tests include creatine kinase MB and cardiac troponin levels. An electrocardiogram (ECG) can reveal alterations in the ST and Q components, which would help differentiate between ST-elevated MI (STEMI) and non-ST-elevated MI (non-STEMI). Other imaging modalities such as cardiac MRI may also be utilized as part of the assessment.
