Hypertension represents a major risk factor for myocardial infarction and the most important risk factor for stroke. Two thirds of strokes and half of myocardial infarctions arise from a systolic blood pressure > 115 mmHg. The relationship between blood pressure and cardiovascular diseases is log linear. Hypertension is the leading risk factor of preventable deaths worldwide. High blood pressure accounts for 26% of the total mortality in Germany. The prevalence of hypertension in Germany (55%) is twice the rate in Canada and the USA. Health care indicators such as hypertension awareness, treatment and control in Germany trail behind when compared internationally. Hypertension treatment and control in Germany amount to 26% and 8%, respectively. Concepts for the improvement of health care in patients with high blood pressure are, e.g., improvement of guideline awareness among physicians as well as quality-oriented payment for health care.

Background: Angina pectoris refractory to conventional medical treatment is a common phenomenon in patients with stable coronary artery disease (CAD). Many of these patients suffer from depression and generate substantial costs in the healthcare system. Therefore, the development of new therapeutic concepts is of particular importance. This study investigated whether professional, structured humor training has a positive effect on the symptoms of patients with treatment refractory angina pectoris., Methods: Between 2013 and 2014 a total of 35 patients with stable CAD were included. Enrolment was possible if patients suffered from treatment refractory angina pectoris (Canadian Cardiovascular Society, CCS grades II-IV) despite optimal antianginal medication and exhaustion of options for myocardial revascularization. Previously, 25.8% of the patients had had a myocardial infarction. In this study, a professional humor coaching was conducted with a duration of 7 weeks. In order to evaluate the effects of the coaching, the following examinations were performed before and after the intervention: exercise stress test (treadmill), hair segment cortisol analysis, Beck Depression Inventory (BDI), the Trier Inventory for the Assessment of Chronic Stress (TICS) and the State-Trait-Cheerfulness Inventory (STCI)., Results: Out of the 35 initially recruited patients 31 completed the study. The mean age was 65.5 years and 94.5% were female. There was a significant improvement in cheerfulness (STCI, pre 23.3 ± 5.4, post 27.5 ± 5, p = 0,03). This effect was even stronger in a subgroup analysis in which only female patients were included (pre 23.6 ± 5.5, post 27.7 ± 4.6, p = 0.003). The results of the BDI showed a remarkable improvement in the pre-post analysis (pre 14.6 ± 8.1, post 11.0 ± 6.5, p = 0.064). Analyzing only the female patients, this difference became significant (pre 13.1 ± 6.4, post 9.9 ± 4.6 p = 0,037). The hair segment investigations showed that patients who had a higher cortisol level in the beginning (>25. percentile, n = 22) showed a significant reduction of the cortisol concentration (pre 6.54 pg/mg, 3.78-12.12 pg/mg, post 3.65 pg/mg, 2.82-7.68 pg/mg, p = 0.029)., Conclusion: Patients with refractory angina pectoris and stable CAD benefit from a professional humor coaching. This effect was shown in a) a significant decrease in cortisol concentrations in the hair segment analysis, b) an improvement in cheerfulness in the STCI and c) a significant difference in the BDI between pre-post values.
