Objectives: To know the arterial hypertension prevalencia and hypertension control in the patients income by heart failure. Methods: A cross-sectional study of the intaked patients in the Internal Medicine Service in the Hospital Clínico Universitario de Santiago de Compostela between 1999 to 2003. The variables analized were: sex, age, days of hospital stay, number of intaked by failure cardiac, reason for admission (guide symptom), hypertension, diabetes mellitus, cardiac disease, fibrillation atrium, previous treatment with beta-blockers, blood pressure in the admission moment, to make echocardiography, disfunction systolic, etiology, deceased, treatment at the end. The statistical analysis was performed with cualitative and cuantitative measures, chi-cuadrado and t-student, and multivariant analyses. Results: 248 patients were accepted for the study, and 100 were hypertensive patients (41.8%). We observed more women than men in hypertensive group (63.0%) and in non hypertensive group (51.1%). The median age was 77 years old in both groups. The median income was 11 days. The number of patients with diabetes mellitus and ischemic cardiopathy was bigger in hypertension group (43.0 vs. 22.3%), p < 0.001; (38 vs. 21.6%), p = 0.005. The most frequent simptom was the dyspnea (66,9%), in both groups, p = 0.62. The 62.6% of the patients were bad control of blood pressures. The prevalence of bad control in hypertensive patients was bigger tha non-hypertensive patients (76.9 vs. 59.4%, p = 0.01). The pharmacologic treatment more prescribed in hypertensive patients ECAI or AAR-II (62.6 vs. 26.8%, p < 0.001). And the diuretics wee more prescribed in non-hypertensive patients (91.1 vs. 81.1%, p = 0.03). Conclusions: The prevalence of diabetes mellitus is associated with hypertension in the patients. The ECAI prescription was acceptable. The number of echocardiograms practiced to the patients is smaller that the number advised by international associations and smaller to the cardiologist registers. The beta-blockers is smaller too.
