[Prevalence and severity of hypertensive emergencies and outbreaks in the hospital emergency department of CHU Timone at Marseille: Follow-up in three months of hospitalized patients].

Goal: Evaluation of the prevalence and severity of hypertensive emergencies and crisis in an Emergency Service of Timone hospital in Marseille and follow-up of 3 months of hospitalized emergencies.

Methods: This study was conducted in the Emergency Department between April 1 and June 30, 2015. All patients with BP>180 and/or 110mmHg was recorded and classified in true emergencies (presence of visceral pain) and hypertensive isolated crisis. A phone follow-up patients was organized.

Results: During this period, 170 patients were identified: 95 (56%) hypertensive crisis and 75 (44%) hypertensive emergencies: 25 OAP (33%), 18 ischemic stroke (24%), 15 hemorrhagic stroke (20%), 9 angina (12%) and 8 different. The clinical characteristics of hypertensive emergencies are preferentially dyspnea (27%) motor deficit (36%), and chest pain (16%). The BP of hypertensive emergencies at their admission (3 measurements, oscillometric automatic device) is close to the hypertensive crisis (198.17±19.3 to 96.4±21.2mmHg versus 191±31.6 to 96.12±21). The BP controlled after 15minutes of rest is lower for crisis compared to real emergencies (152±47 to 79±28 vs. 174±31 to 86±26). Age emergency is larger (77±14 vs. 67±17), the number of slightly larger drug (1.79 versus 1.67±1±1). Telephone follow-up was performed after an average period of three months. Ninety-nine patients were contacted by telephone: 46 patients who were admitted for hypertensive emergency patients and 53 for a push. Eighteen deaths have been recorded, including 15 among hypertensive emergencies (9 in hemorrhagic stroke, 5 for ischemic stroke, and 1 for OAP) with 5-hospital deaths within 48hours after admission and 10 within 3 months in patients hospitalized with hypertensive emergency or 33%. Seventy-seven patients out of 99 had been reviewed by their attending physicians. A questionnaire was sent by mail to patients who have not answered the phone contacts, and responses are pending.

Conclusion: Hypertensive emergencies hospitalized in Timone Hospital represent 44% of patients hospitalized for emergency HTA. Their gravity is 1/3 since most patients die within three months warranting closer management of these fragile patients by creating a specialized consulting postemergency.
