Introduction and objective: Cardiovascular diseases are one of the leading causes of death in the world. The most common risk factor for the development of this group of diseases is arterial hypertension (Latin: hypertonia arterialis, HA). HA may affect up to 11 million Poles and this number may increase by half by 2035. The persistence of elevated blood pressure values and the presence of symptoms accompanying HA prompts patients to call the Emergency Medical Service (EMS). Aim: to analyze the symptoms accompanying arterial hypertension during the intervention of EMS. Material and methods: The study used an analysis of the medical documentation of the Emergency Medical Card collected in the period 04.2019-02.2021. The study included 302 patients whose main diagnosis at the time of the Emergency Medical Services visit was disease code I 10: Spontaneous (primary) hypertension according to the ICD-10 classification. Microsoft Excel and Statistica 13 programs were used for statistical analysis of the materials. Results: Women constituted the majority of the analyzed group (n = 208; 68.9%). The mean age of the respondents was 69 years old, and the women were older (72 years vs 64 years). The mean systolic blood pressure was 189mmHg, and the diastolic blood pressure was 100mmHg. The mean systolic blood pressure in women was higher than in men (190.45 mmHG vs 185.65 mmHg). The most common accompanying symptoms were: malaise, headaches and dizziness. Headaches dominated in women, while in men, chest pain and malaise were predominant. Headache occurred in 23.6% of the examined women and in 14.9% of men. In turn, the discomfort/pain in the chest concerned men in 23.4% of cases, and women in 12.5%. Conclusions: EMS interventions due to HA most often refer to elderly women and their systolic blood pressure values are higher than in men. The symptoms associated with high blood pressure are common. Headaches dominate in women and chest pains in men.
