Psychological distress is independently related to new coronary events at 8 years' follow-up in elderly primary care patients with hypertension.

OBJECTIVE: Occurrence of psychological distress in hypertensive patients could have a negative synergistic effect on future cardiovascular events (CVEs). The aim of this study was to determine the association between anxiety or depressive symptoms in elderly hypertensive primary care patients and the development of new CVEs and all-cause mortality. METHODS: A prospective cohort study was conducted in five Dutch general practices between June 2010 and January 2012. Patients with primary care managed hypertension, aged 60-85 years, were included and completed the GAD-7 and PHQ-9, measuring anxiety and depressive symptoms respectively. The incidence of new CVEs (coronary event, cerebrovascular disease, atrial fibrillation and heart failure) and all-cause mortality at 8 years' follow-up was recorded by data extraction of the digital information systems. RESULTS: Among the 555 included participants (mean age 70 ± 6.6 years; 56% female), 29 (5.2%) had a new coronary event, 42 (7.6%) a cerebrovascular disease, 57 (10.3%) atrial fibrillation, 22 (4%) heart failure and 68 (12.3%) died. Elevated anxiety and depression scores increased the risk of a coronary event independently and significantly by 12% (HR 1.12; 95% CI [1.04-1.22], p = 0.005) and 18% (HR 1.18; 95% CI [1.08-1.28], p < 0.0001), respectively, adjusted for relevant (Framingham) baseline covariates. No associations were found with regard to other CVEs and all-cause mortality. CONCLUSION: In a random sample of elderly primary care hypertension patients there was a significant association between psychological distress and the occurrence of new coronary events after 8 years' follow-up but not with other CVEs and all-cause mortality.

Beta-blockers and depression in elderly hypertension patients in primary care.

BACKGROUND AND OBJECTIVES: Previous findings regarding a possible association between beta-blocker use and depression are mixed. To our knowledge there have been no studies investigating the association of beta-blockers with depression in primary care hypertension patients without previous myocardial infarction. The aim of this study was to determine the relation between lipophilic beta-blocker use and depression in elderly primary care patients with hypertension. METHODS: This was a cross-sectional study in primary care practices located in the South of The Netherlands. Primary care hypertension patients without previous myocardial infarction or heart failure (n=573), aged between 60 and 85 years (mean age=70±6.6), were included. All patients underwent a structured interview that included a self-report questionnaire to assess depression (PHQ-9), which was divided in four groups (PHQ-9 score of 0, 1--3, 4--8, 9 or higher). RESULTS: A PHQ-9 score of 0 was more prevalent in non-beta-blocker users versus lipophilic beta-blocker users (46% versus 35%), a PHQ-9 score of 4--8 was less prevalent in non-beta-blocker users as compared with lipophilic beta-blocker users (14% versus 25%). A chi-squared test showed that lipophilic beta-blocker users as compared to non-beta-blockers users were more likely to be in a higher depression category. Ordinal regression showed a significant relationship between use of lipophilic beta-blockers and depression (OR=1.60, 95% CI=1.08--2.36) when adjusting for potential confounders. CONCLUSIONS: Our findings show that primary care hypertension patients who use a lipophilic beta-blocker are more likely to have higher depression scores than those who do not use a lipophilic beta-blocker.
