Influence of individualized prevention recommendations after one year on the control of hypertension in 3,868 follow-up participants of the ELITE study.

OBJECTIVES: The ELITE study (German acronym for "Nutrition, lifestyle and individual information for prevention of heart attack, stroke and dementia") prospectively collects data on hypertension, cardiovascular risk factors (RF), dietary habits, physical activity, cognitive function, and quality of life in North-West Germany, which will then be improved through targeted individual information. The aim of the study is to improve the health of the participants in the long term and to identify reasons for a lack of implementation of prevention measures. METHODS: Of 4,602 included subjects, 3,868 could be studied so far at one-year follow-up. Blood pressure (BP) was measured according to the guidelines at admission and blood pressure history, premedication, sports behaviour and BMI were recorded by means of questionnaires and compared with the data collected in the follow-up examination after one year. RESULTS: The participants were evaluated in 4 groups (G): G1 - normotensive patients (n = 1,558), G2 - controlled hypertensive patients (n = 502), G3 - untreated uncontrolled hypertensive patients (n = 1,080), G4 - treated uncontrolled hypertensive patients (n = 728). In G1 blood pressure (RR) remained unchanged from 126.3/77.8 to 127.8/78.5, in G2 there was a significant (p < 0.001) RR increase from 128.1/77.0 to 134.9/79.8. In G3 and G4 RR decreased significantly (p < 0.001) from 149.9/90.0 to 143.5/86.9 and from 153.1/87.5 to 146.2 84.1 mmHg, respectively. In G3 and G4, RR decreased in 56.1% and 56.3% of subjects and increased in 18% and 21%, respectively. In contrast, RR increase was found more frequently in G1 and G2 (34.3% and 51%, respectively), and RR decrease less frequently (25.4 and 20.7%, respectively). The main reasons for RR decrease were weight loss, more exercise, and more antihypertensives. Frequently, improved compliance and dietary changes were given as reasons. As expected, the opposite often led to RR increase. CONCLUSION: 56% of the hypertensive participants succeeded in lowering their blood pressure, whereas there was a significant increase in blood pressure, especially in those who were well controlled with antihypertensives. This underlines the need to further motivate normotensive patients to maintain their normotension. The results show that the combination of individual written education and lifestyle interventions are an effective tool for the public health sector to combat hypertension. In our participants, lifestyle interventions have a significant impact on BP change. It should be noted critically that there are still too many patients who have not been reached.

Influence of cardiovascular risk factors on arterial hypertension and mild cognitive impairment in 4602 participants of the ELITE study.

BACKGROUND: In ELITE (Ernährung, Lebensstil und individuelle Information zur Verhinderung von Herzinfarkt, Schlaganfall und Demenz; german for: Nutrition, Lifestyle and Individual Information for the Prevention of Heart Attack, Stroke and Dementia) data on cardiovascular risk factors, cognitive function and quality of life are prospectively collected, which will be improved through targeted individual information. The aim is to improve the health of the participants and identify the reasons for the lack of implementation. METHODS: Risk factors of 4602 participants were linked to (controlled) hypertension and mild cognitive impairment (MCI). Blood pressure was measured according to the guidelines and the DEMTECT- test was used to detect MCI. RESULTS: The most common risk factor was hypertension (60%). Hypertensive patients were older (56.1 and 44.7 years), had a higher BMI (28 and 24.8 kg/m), frequently physical inactive (26 and 32.4%), diabetes (9.3 and 1.3%), higher LDL (134.7 and 124.1 mg/dl), higher triglycerides (169.6 and 124.8 mg/dl) and lower HDL (57.9 and 65.5 mg/dl) compared with normotensives (P < 0.001). Controlled hypertensive patients are less common men (46.1 and 52.1%, P < 0.001), have a lower BMI (28.3 and 29.1 kg/m, P < 0.001), lower LDL (129.0 and 135.6 mg/dl, P = 0.004) and lower triglycerides (162.5 and 182.3 mg/dl, P = 0.001) compared with treated uncontrolled hypertensive patients. Antihypertensives per person (2.015; 2.017) do not differ. The prevalence of MCI is highly significantly associated with the number of risk factors. in participants without risk factors, the prevalence is 3.9%, in participants with 4 risk factors, 16.3%. In hypertensive patients, the frequency is 11.8% compared with 4.8% for normotensives (P < 0.001). The occurrence of MCI depends significantly from age, blood pressure and diabetes CONCLUSION:: The frequency of MCI is highly significantly associated with the number of cardiovascular risk factors, regardless of age. The prevalence was particularly high among hypertensive patients, which is not often described. The occurrence of MCI depends significantly from age, blood pressure and diabetes. The metabolic syndrome and lack of exercise complicate blood pressure control.
