Apatient has arrived at the emergency room with a myocardial infarction. what is this patient most likely suffering from? a. hypertension b. coronary disease c. cardiac dysrhythmias d. pulmonary embolism

B.coronary disease

Explanation:

    Myocardial infarction, or heart attack, is the death of cells in a region of the heart muscle due to the formation of a clot that interrupts blood flow suddenly and intensely.  

   The main cause of the infarction is atherosclerosis, a disease in which plaques accumulate inside the coronary arteries, eventually obstructing them. In most cases, myocardial infarction occurs when one of these plaques ruptures, leading to clot formation and interruption of blood flow, leading to decreased oxygenation of cardiac muscle (myocardial) cells.

   Infarction can occur in many parts of the heart, depending on which artery has been blocked. In rare cases, infarction can occur by contracting the artery, disrupting blood flow, or by detaching a clot that originates within the heart and lodges within the vessels.
