A 65-year-old woman with history of type 2 diabetes mellitus for the last 8 years dies in a hospital She had no other significant medical history. Which of the following is the most likely cause of her death?
**Core Concept**
Diabetic patients are at increased risk of cardiovascular disease due to chronic hyperglycemia-induced vascular damage and inflammation. This can lead to atherosclerosis, myocardial infarction, and other cardiovascular events.
**Why the Correct Answer is Right**
The most common cause of death in diabetic patients is cardiovascular disease. In this case, the patient's 8-year history of type 2 diabetes mellitus has likely led to the development of atherosclerosis, which can cause myocardial infarction (heart attack). The patient's age and comorbid condition also increase the risk of cardiovascular disease. The pathophysiology involves chronic hyperglycemia-induced damage to the blood vessels, leading to the formation of atherosclerotic plaques, which can rupture and cause a myocardial infarction.
**Why Each Wrong Option is Incorrect**
**Option A:** While diabetic patients are at increased risk of infections, there is no indication in the scenario that the patient had an infection that would have led to her death.
**Option B:** Diabetic patients can develop kidney disease, but there is no indication in the scenario that the patient had end-stage renal disease or an acute kidney injury that would have led to her death.
**Option C:** While diabetic patients can develop neuropathy, there is no indication in the scenario that the patient had a severe neuropathic complication that would have led to her death.
**Option D:** Diabetic patients can develop retinopathy, but there is no indication in the scenario that the patient had a severe visual impairment or blindness that would have led to her death.
**Clinical Pearl / High-Yield Fact**
Diabetic patients are at increased risk of cardiovascular disease, and it is essential to manage their risk factors, including hypertension, hyperlipidemia, and smoking, to prevent cardiovascular events.
**Correct Answer:** C. Myocardial infarction.
