GARCIA BELLO, Laura Beatriz; PEDERZANI, Lino Marcelo; FRETES, Ariel  and  CENTURION, Osmar Antonio. Clinical characteristics of patients with hypertensive crisis who attend a medical emergency service. Rev. virtual Soc. Parag. Med. Int. [online]. 2020, vol.7, n.1, pp.42-49. ISSN 2312-3893.


Blood pressure levels above normal levels increase the risk of cardiovascular and cerebral diseases. Complications caused by hypertensive crises are very dangerous and often fatal. It is very important to know their clinical characteristics well to try to counteract their evolution.


To describe the behavior of hypertensive crises in 500 patients of the Emergency Service of the Hospital de Clínicas, in the period from January to June 2018.


Descriptive and retrospective study. The reception and emergency classification sheets and the medical records of patients admitted with hypertensive crisis were used. Absolute and relative frequencies (percentage) were used to summarize the information, and tables for presentation.


In the study the male sex prevailed, with 351 (70%) patients, and 149 (30%) of female sex. The age group in which there was a greater prevalence of patients (49%) was 50-59 years old. A predominance of hypertensive urgencies was observed with 399 (79.8%) patients, while only 101 (20.2%) patients developed hypertensive emergencies. The most frequently damaged target organ was the brain in 43 (42.6%) patients with a stroke, followed by acute coronary syndrome in 34 (33.7%) patients. The most frequent electrocardiographic alteration was left ventricular hypertrophy in 187 (37.4%) patients, and in the second place was the ST elevation, which occurred in 111 (22.2%) patients.


The most significant complications and findings in these patients with hypertensive crises were cerebrovascular accidents and acute coronary syndrome, as well as left ventricular hypertrophy and ST-segment elevation within electrocardiographic abnormalities.
