Cardiovascular risk stratification in primary care patients with arterial hypertension: Results from the Swiss Hypertension Cohort Study (HccH).

AIMS: Few data are available on cardiovascular risk stratification in primary care patients treated for arterial hypertension. This study aimed at evaluating the cardiovascular risk profile of hypertensive patients included into the Swiss Hypertension Cohort Study according to the 2013 European Society of Hypertension/European Society of Cardiology Guidelines. METHODS: The Swiss Hypertension Cohort Study is a prospective, observational study conducted by the Centre for Primary Health Care of the University of Basel from 2006 to 2013. Patients with a diagnosis of arterial hypertension (office blood pressure measurement ≥140/90 mmHg) were enrolled. Office blood pressure measurement, cardiovascular risk factors, subclinical organ damage, diabetes mellitus, and established cardiovascular and renal disease were recorded at baseline and at an annual interval during routine consultations by general practitioners in Switzerland. RESULTS: In total, 1003 patients were eligible for analysis (55.6% male, mean age: 64.0 ± 13.2 years). At baseline, 78.5% of patients presented with either more than three additional cardiovascular risk factors, diabetes mellitus or subclinical organ damage, while 44.4% of patients had a high or very high overall cardiovascular risk. Cardiovascular risk factors and information about diabetes mellitus, established cardiovascular disease and renal disease were recorded mostly completely, whereas substantial gaps were revealed regarding the assessment of subclinical organ damage. CONCLUSION: The present findings demonstrate that the majority of primary care patients with arterial hypertension bear a substantial number of additional cardiovascular risk factors, subclinical and/or established organ damage. This emphasizes the need for continuous cardiovascular risk stratification and adequate treatment of arterial hypertension in Switzerland.

Arterial hypertension is a leading problem in general practice. Nevertheless, reliable epidemiological and outcome data on hypertensive patients obtained directly from GPs are scarce. We report some results of our GP cohort "HccHs" of the Institute of general practice Basel. Swiss GPs fill in relevant baseline and follow-up data of their own hypertensive patients in an internnn based questionnaire The first results show a good blood pressure control. 94% of 950 patients receive antihypertensive drug treatment. 24-hour-blood pressure-measurement is helpful for baseline diagnosis and in drug treated hypertensive patients. 24-hour-blood pressure-measurement identifies patients with elevated office but normal 24-hour blood pressure with good prognosis.

High prevalence of newly detected hypertension in hospitalized patients: the value of inhospital 24-h blood pressure measurement.

OBJECTIVE: Screening for hypertension in hospitalized patients could reduce the number of individuals with unrecognized hypertension. We hypothesized that 24-h blood pressure monitoring is an adequate tool to detect unrecognized hypertension among inpatients. METHODS: Clinically stable inpatients in the Department of Internal Medicine, Department of Visceral Surgery and Department of Orthopaedics were included in the cross-sectional study. Every patient underwent inhospital 24-h blood pressure measurement. Previously unknown hypertension was defined as 24-h blood pressure of at least 125/80 mmHg in the absence of known hypertension. Forty-two patients had an additional 24-h blood pressure measurement after discharge, to compare mean inhospital and outpatient 24-h blood pressure values. RESULTS: In 314 consecutive inpatients, 24-h blood pressure measurement was performed. Among 139 patients without known hypertension, 53 were hypertensive. The mean routine and 24-h blood pressures in these patients were 135/77 and 137/82 mmHg, respectively. Thirty-seven of these patients had normal routine blood pressure and could be detected only by 24-h blood pressure measurement. Patients with unknown hypertension had a marked cardiovascular risk profile, 26 being at high or very high cardiovascular risk. However, documented cardiovascular disease was present in only seven patients, suggesting that effective treatment could prevent a considerable number of cardiovascular events. The agreement between inhospital and outpatient 24-h blood pressure measurement in 42 patients was good. CONCLUSIONS: By performing inhospital 24-h blood pressure measurement, a considerable number of patients with previously unknown hypertension can be detected.
