INTRODUCTION: Acute severe elevation of blood pressure (BP) is a common clinical event, that can present as hypertensive emergency (HTNE) and hypertensive urgency (HTNU). HTNE results in life-threatening target organ damage, including myocardial infarction, pulmonary edema, stroke, and acute kidney injury. It is associated with high utilization of healthcare and increased cost. HTNU is high BP without acute serious complications.
AIM: The purpose of this review was to examine the clinical-epidemiological characteristics of patients with HTNE and propose a risk stratification framework to differentiate between the two conditions, since prognosis, setting of therapy and treatment is vastly different.
METHODS: Systematic review.
RESULTS: Fourteen full-text studies were included in this review. In comparison with HTNU, patients with HTNE had higher mean systolic (mean difference 2.413, 95% CI 0.477, 4.350) and diastolic BP (mean difference 2.043, 95% CI 0.624, 3.461). HTNE were more prevalent in men (OR 1.390, 95% CI 1.207, 1.601), older adults (mean difference 5.282, 95% CI 3.229, 7.335) and those with diabetes (OR 1.723, 95% CI 1.485, 2.000). Non-adherence to BP medications (OR 0.939, 95% CI 0.647, 1.363) and unawareness of hypertension diagnosis (OR 0.807, 95% CI 0.564, 1.154) did not elevate the risk of HTNE.
CONCLUSIONS: Systolic and diastolic BP are marginally higher in patients with HTNE. Given that these differences are not clinically significant, other epidemiological and medical characteristics (older age, male sex, cardiometabolic comorbidities) as well as patient's presentation should be considered to differentiate between HTNU and HTNE.
