  abstract  = {AIM To determine the prevalence of depression and its risk factors among patients with coronary heart disease (CHD) treated in German primary care practices. METHODS Longitudinal data from nationwide general practices in Germany (n = 1072) were analyzed. Individuals initially diagnosed with CHD (2009-2013) were identified, and 59992 patients were included and matched (1: 1) to 59992 controls. The primary outcome measure was an initial diagnosis of depression within five years after the index date among patients with and without CHD. Cox proportional hazards models were used to adjust for confounders. RESULTS Mean age was equal to 68.0 years (SD = 11.3). A total of 55.9\% of patients were men. After a five-year follow-up, 21.8\% of the CHD group and 14.2\% of the control group were diagnosed with depression (P < 0.001). In the multivariate regression model, CHD was a strong risk factor for developing depression (HR = 1.54, 95\% CI: 1.49-1.59, P < 0.001). Prior depressive episodes, dementia, and eight other chronic conditions were associated with a higher risk of developing depression. Interestingly, older patients and women were also more likely to be diagnosed with depression compared with younger patients and men, respectively. CONCLUSION The risk of depression is significantly increased among patients with CHD compared with patients without CHD treated in primary care practices in Germany. CHD patients should be routinely screened for depression to ensure improved treatment and management.},

  abstract  = {Background: The goal of this study was to estimate the prevalence of and risk factors for diagnosed depression in heart failure (HF) patients in German primary care practices. Methods: This study was a retrospective database analysis in Germany utilizing the Disease Analyzer (R) Database (IMS Health, Germany). The study population included 132,994 patients between 40 and 90 years of age from 1,072 primary care practices. The observation period was between 2004 and 2013. Follow-up lasted up to five years and ended in April 2015. A total of 66,497 HF patients were selected after applying exclusion criteria. The same number of 66,497 controls were chosen and were matched (1:1) to HF patients on the basis of age, sex, health insurance, depression diagnosis in the past, and follow-up duration after index date. Results: HF was a strong risk factor for diagnosed depression (p < 0.0001). A total of 10.5\% of HF patients and 6.3\% of matched controls developed depression after one year of follow-up (p < 0.001). Depression was documented in 28.9\% of the HF group and 18.2\% of the control group after the five-year follow-up (p < 0.001). Cancer, dementia, osteoporosis, stroke, and osteoarthritis were associated with a higher risk of developing depression. Male gender and private health insurance were associated with lower risk of depression. Conclusions: The risk of diagnosed depression is significantly increased in patients with HF compared to patients without HF in primary care practices in Germany.},

  abstract  = {Objective: To estimate the prevalence and the type of antidepressant medication prescribed by German psychiatrists to patients with depression and cardiovascular diseases (CVD). Methods: This study was a retrospective database analysis in Germany using the Disease Analyzer Database (IMS Health, Germany). The study population included 2,288 CVD patients between 40 and 90 years of age from 175 psychiatric practices. The observation period was between 2004 and 2013. Follow-up lasted up to 12 months and ended in April 2015. Also included were 2,288 non-CVD controls matched (1 : 1) to CVD cases on the basis of age, gender, health insurance coverage, depression severity, and diagnosing physician. Results: Mean age was 68.6 years. 46.2\% of patients were men, and 5.9\% had private health insurance coverage. Mild, moderate, or severe depression was present in 18.7\%, 60.7\%, and 20.6\% of patients, respectively. Most patients had treatment within a year, many of them immediately after depression diagnosis. Patients with moderate and severe depression were more likely to receive treatment than patients with mild depression. There was no difference between CVD and non-CVD in the proportion of patients treated. Nonetheless, CVD patients received selective serotonin reuptake inhibitors / serotonin-noradrenaline reuptake inhibitors (SSRIs/SNRIs) significantly more frequently. Conversely, patients without CVD were more often treated with TCA. Conclusion: There was no association between CVD and the initiation of depression treatment. Furthermore, CVD patients received SSRIs/SNRIs more frequently.},
