A white female client is admitted to an acute care facility with a diagnosis of cerebrovascular accident (CVA). Her history reveals bronchial asthma, exogenous obesity, and iron deficiency anemia. Which history finding is a risk factor for CVA?
A. Caucasian race
B. Female sex
C. Obesity
D. Bronchial asthma
Correct Answer: C. Obesity
Obesity is a risk factor for CVA. Other risk factors include a history of ischemic episodes, cardiovascular disease, diabetes mellitus, atherosclerosis of the cranial vessels, hypertension, polycythemia, smoking, hypercholesterolemia, oral contraceptive use, emotional stress, family history of CVA, and advancing age.
Option A: Of all the risk factors, hypertension is the most common modifiable risk factor for stroke. Hypertension is most prevalent in African-Americans and also occurs earlier in life. According to JNC8, the recommended blood pressure targets in patients with stroke should be less than 140/90 mm Hg.
Option B: One-third of the adults in the USA have elevated low-density lipoprotein (LDL), leading to plaque formation in the intracerebral vasculature. Eventually, due to the excessive plaque build-up thrombotic strokes occur.
Option D: Ischemic etiologies can further be divided into embolic, thrombotic, and lacunar. In general, the common risk factors for stroke include hypertension, diabetes, smoking, obesity, atrial fibrillation, and drug use.
