After myocardial infarction, serum glucose levels and free fatty acids are both increased. What type of physiologic changes are these?
A) electrophysiologic
B) Hematologic
C) Mechanical
D) Metabolic
After myocardial infarction, the increase in serum glucose levels and free fatty acids are examples of D) Metabolic changes. These changes reflect the body's response to the stress of a heart attack and its attempt to provide the necessary energy for recovery.
The increase in serum glucose levels and free fatty acids after a myocardial infarction (heart attack) are metabolic changes. During a heart attack, the heart muscle is deprived of oxygen, which leads to a decrease in energy production via aerobic metabolism. As a result, the body switches to anaerobic metabolism, which produces more glucose and free fatty acids to provide energy to the heart and other tissues. The increase in serum glucose levels and free fatty acids reflects this metabolic shift.

Cardiac tamponade
Occlusive arterial disease
hemophilia
Raynaud's phenomenon
Heart Failure
Thrombophlebitis
DIC
Sickle cell disease
Bleeding, blood clots, bruising, and drop in blood pressure can result from various conditions. Atrial fibrillation, myocardial infarction, and heart failure can lead to blood clots and alterations in blood pressure due to irregular heartbeats and compromised heart function.
Cardiac tamponade may cause a drop in blood pressure as fluid accumulation around the heart impairs its ability to pump blood effectively. Occlusive arterial disease, thrombophlebitis, and disseminated intravascular coagulation (DIC) can cause blood clots in the arteries and veins, leading to decreased blood flow and increased pressure. Hemophilia is a genetic disorder that impairs blood clotting, leading to excessive bleeding and bruising. Sickle cell disease can cause blood clots due to the abnormal shape of red blood cells, which can obstruct blood vessels and compromise circulation. Raynaud's phenomenon affects blood vessels in the extremities, causing them to narrow in response to cold or stress. This can lead to reduced blood flow and, in severe cases, may cause blood clots.
