P-498: Blood pressure at hospital discharge after acute coronary event: Influence on midterm blood pressure control

The difficulty in controlling hypertension in coronary patients has been underlined. The aim of the study was to assess blood pressure profile (BP) at hospital discharge and after 6 months follow-up in a large population of survivors of an acute coronary syndrome. An observational study was conducted in France in 77 cardiological centers. The medical records of all patients admitted in these hospitals on January 1998 for a myocardial infarction or unstable angina and who survived were studied. Clinical characteristics and BP at hospital discharge and after 6 months follow-up were recorded. Patients with blood pressure >= 140/90 mmHg were considered as uncontrolled hypertensives. Data were available in 1126 patients of the 1394 patients recruited. At hospital discharge, 368 (32.68%) were uncontrolled hypertensives (HT). At 6 months follow-up 389 (34.55%) patients were uncontrolled HT whom 283 (72.75%) were previously uncontrolled or had a high normal BP. We observed a strong association between blood pressure level at hospital discharge and the six month blood pressure control. (See Table) BP at hospital discharge n=1126 BP > 140/90 at follow up n=389 (34.55%) Normal BP n=554 106 (19.13 %) High normal BP n=204 81 (39.70 %) Hypertension stade 1 n=293 144 (49.14 %) Hypertension stade 2 and stade 3 n=75 58 (77.33 %)
