A nurse is reviewing the medical history of a client who has angina. Which of the following findings in the client's medical record should the nurse identify as a risk factor for angina?

A. Seizure disorder is not a direct risk factor for angina. While seizures may affect overall health status and oxygen demand during an event, they do not contribute to atherosclerosis or coronary artery disease, which are the primary causes of angina. B. Hypotension is not a risk factor for angina. In fact, angina is more commonly associated with conditions that reduce coronary perfusion due to narrowed arteries or increased oxygen demand. Hypotension may reduce perfusion overall, but it is not a chronic risk factor for developing coronary artery disease. C. Hyponatremia is not associated with the development of angina. It reflects an electrolyte imbalance often related to fluid status, renal issues, or medication effects, but it does not contribute to coronary artery narrowing or ischemia. D. Hyperlipidemia is the correct answer because it is a major modifiable risk factor for angina. Elevated levels of cholesterol, particularly LDL, contribute to atherosclerotic plaque formation in coronary arteries. This leads to narrowed vessels, reduced blood flow to the myocardium, and increased risk of ischemia and angina.
