Therefore, future research should incorporate the following predictors in the model: demographics such as age, gender, history of diabetes, smoking, and alcohol consumption; physical examination such as BMI, blood pressure, waist, and neck circumference; clinical data such as CRP, infarct location, and heart failure; sleep characteristic such as snoring, stop breathing, and ESS; and symptoms or severity associated with stroke such as dysphagia, nocturia, and NIHSS. This evidence concerns the gene CRP and heart failure.
