Final answer:
A combination of a (+) EKG and a (+) blood work can point to a diagnosis of myocardial infarction (MI). A combination of a (-) EKG and a (+) blood work may indicate a non-ST elevated MI (non-STEMI). A combination of a (-) EKG and a (-) blood work may not indicate any significant cardiac issues or abnormalities.
Step-by-step explanation:
The combination of a (+) EKG and a (+) blood work can indicate a diagnosis of myocardial infarction (MI) or a heart attack. An MI can be confirmed by examining the patient's ECG, which frequently reveals alterations in the ST and Q components and by blood tests indicating elevated levels of creatine kinase MB and cardiac troponin. These enzymes are released by damaged cardiac muscle cells.
On the other hand, the combination of a (-) EKG and a (+) blood work can be an indication of a non-ST elevated MI (non-STEMI). This type of MI may not show significant changes on the ECG but still show elevated levels of creatine kinase MB and cardiac troponin in the blood.
Lastly, the combination of a (-) EKG and a (-) blood work may not indicate any significant cardiac issues or abnormalities.
