Diabetes High Blood Pressure Unstable Angina High Cholesterol Family History of Heart Disease Increasing Age Smoking

When there is decreased blood supply to the coronary arteries, which tissue of the heart is affected first?

Endocardium

This patient has the most likely diagnosis of:

Myocardial Infarction

Is JT's heart rate in the normal range?

No

JT's EKG shows:

STEMI

QT interval prolongation increases the risk of:

Ventricular Arrhythmia

The QRS complex on an EKG helps us evaluate:

Ventricular contraction(depolarization)

Is JT's blood pressure considered high, low, or normal?

low

Does JT possess any predisposing factors that increase her risk of myocardial infarction?

yes

What is the reason for JT's low blood pressure, despite always having high blood pressure (HTN), and high cholesterol?

At this time, JT's heart muscles are not contracting correctly because there is tissue death and therefore, less blood is being pumped out of the ventricles to the body.

If you want to check for consecutive Myocardial Infarction, which lab value is the most effective?

CK-MB
