Final answer:
Ischemic cardiomyopathy patients presenting with VT may require cardioversion or defibrillation if severe. Diagnosis of MI involves ECG and blood tests for creatine kinase MB and cardiac troponin. Long-term management includes lifestyle changes and medications, with coronary bypass surgery as a potential option.
Step-by-step explanation:
Patients with ischemic cardiomyopathy who present with ventricular tachycardia (VT) should be considered for a variety of treatments depending on the severity and stability of their condition. Those who have severe symptoms or are unstable may need urgent treatment with a controlled electric shock in the form of cardioversion or defibrillation.
For patients with myocardial infarction (MI), the confirmation typically involves an ECG revealing alterations in the ST segment and Q wave, with an elevation of the ST segment often seen in patients with an acute MI. Common blood tests, indicating damage such as elevated levels of creatine kinase MB and cardiac troponin, are also used for diagnosis.
In the long term, patients may need to consider lifestyle changes and a medicine regime to lower blood pressure, cholesterol, lipids, and reduce clotting. Surgical options such as coronary bypass surgery can also be considered, although this procedure does not necessarily increase longevity, and its advisability depends on the individual's overall cardiac capacity and health status.
