C89 CARDIOLOGICAL HYPERTENSIVE EMERGENCIES: REAL WORD DATA COMPARED TO GUIDELINES INDICATIONS

Abstract

Abstract Background The 2018 ESH guidelines have revised the therapeutic goals of cardiological Hypertensive Emergencies (HE) with an indication for a more intensive (target < 140/90 mmHg) and rapid (immediate) Blood Pressure (BP) reduction. Cardiac acute organ damage during HE includes acute myocardial infarction, pulmonary edema, unstable angina pectoris and aortic dissection. However, how much these indications have been applied in clinical practice to date it’s unknown. Aims The first purpose of our study is to analyze the prevalence and clinical characteristics of cardiological HE in our institution. The second purpose is to compare the year before the release of the 2018 guidelines (2017) with the subsequent years (2019) trying to verify adherence to guidelines. Methods This is a single–center retrospective study conducted at the Niguarda Hospital. All patients aged ≥ 18 years with Systolic BP≥ 180 mmHg and/or a Diastolic BP ≥ 120 mmHg with Cardiological Emergency were enrolled. From the Emergency Department (ED) data clinical, anamnestic, blood pressure, symptoms, drug treatment and target achievement were registered. Results Patients with BP > 180/120 mmHg in 2017 were 706 out of a total of 73795 accesses (0.96%) and 601 over 67273 (0.89%) in 2019. 246 (34.84%) in 2017 were HE of which 144 (58.53%) were cardiological: aortic dissection 1 (0.69%), acute coronary syndrome 52 (36.11%), acute pulmonary edema 35 (24.30%), cardiac decompensation 91 (63.19%). During 2019 similar figures were founded with 286 (47.58%) HE of which 286 (47.58%) were cardiological: aortic dissection 2 (1.43%), acute coronary syndrome 43 (30.93%), acute pulmonary edema 20 (14.39%), cardiac decompensation 76 (54.68%). The reduction in BP obtained in ED was significantly greater in 2017 than in 2019 (44.7±31.4 vs 35.4±24.5 mmHg, p = 0.011) with a lower target reaching in 2019 (28.9 vs 51.4%, p<0.001). Pulmonary edema is the cardiological HE on which a greater pressure reduction is obtained and therefore in which the target set by the guidelines is more frequently reached. Conclusions The recommendation for a more intense and rapid BP reduction in cardiological HE seems to be not accepted from ED clinicians that persist to reduce BP accordingly to previous guidelines.
