Objectives: The aim of this research was to determine the outcomes of treatment of arterial hypertension in veterans suffering from posttraumatic stress disorder after one year from the diagnosis. Patients and methods: In the examined period from 2008 to 2014. the study included one hundred patients who were first diagnosed with arterial hypertension at the time. Half of the patients had PTSD diagnosis and they do the main group of the examinees, and the other half had no PTSD diagnosis, and they make the control group. Involvement of patients was not at the same time and everyone was followed equally, one year. Results: The mean age at the time of diagnosis in the main group was 55.31 (9.42) years; and in the control group 53.82 (8.84) years. At the time of diagnosis, in the control group, the majority of respondents were employed (44%), while the main group was mostly retired (19%). In the control group, the highest number of subjects was married (n = 40, 80%), and in the test group the most common were also married, but only 54%. PTSD had no influence on the value of systolic and diastolic pressure when setting the diagnosis. The median value based on which the diagnosed arterial hypertension was for systolic pressure of 160 (150-170) mm Hg for both groups, while mean diastolic blood pressure in the test group was 95 (90-100) mm Hg and in control group 100 (90-100) mm Hg. In the largest number of subjects, hypertension was diagnosed by a family medicine practitioner and treatment started with hygienic dietary measures, and the first prescribed drug was ace inhibitor. Patients of the control group came more often to family medicine clinics due to hypertension in the year after diagnosis (7,49 ± 4,38) compared to patients in the test group (6,17 ± 3,24). Patients in the test group spent more medicaments, that were not antihypertension medicaments daily (4 (3+6)), over the control group ((2 (1+1)) per day. In both groups, most of the patients did not change the dose or type of antihypertensive medicament, and no dose or type dependence with PTSD drug was established. Most patients were not on sick leave, and there was no dependence between the use of sick leave and PTSD (p> 0.05) Most of the patients achieved normotension and no dependence on normotensis and PTSD disease (p> 0) was established. Dependence between other diseases and PTSD disease was established where patients with PTSD had a greater number of other diseases compared to the control group (p <0.001). Diabetes mellitus was statistically significantly more prevalent among patients with PTSD. In the second consecutive measurement, systolic pressure was statistically significantly lower in the control group relative to the test group. The conclusion was made on the basis of an empirical p value of 0.035. Conclusion: PTSD had no influence on the pressure value when setting the diagnosis. Respondents from the test group were in a smaller number of marriages than those in the control group. Respondents from the control group were employed in larger number than test subjects. The diagnosis of arterial hypertension has in most cases been made by a family medicine physician. Respondents from the control group visited the family medicine physician more frequently due to the diagnosis of elevated arterial pressure. The first therapy for arterial hypertension was hygienic-dieting measures and the first drug ace inhibitor. PTSD-treated subjects had more comorbidity and took more medications daily than those in the control group. After a one-year period, the systolic pressure in subjects with PTSD was statistically significantly higher in the second consecutive measurement than in the control group. The percentage of normotensive subjects was statistically significantly higher in the control group.
