Hypertension and psychiatric morbidity: a tertiary care setting experience

Arterial hypertension is one of the most important risk factor for cardiovascular disease, the main cause of death in Brazil. Hypertensive patients that have treated in tertiary care hospitals have shown elevated co-morbidity including psychiatric disturbances. Our objective is to study psychiatric co-morbidity among severe hypertensive patients. This study was performed in an out-patient clinic of tertiary medical care setting. Forty-one patients were enrolled in this research (26 women, 15 men). They were submitted to a clinical interview and answering the PRIME-MD, a specific questionnaire for diagnosis of psychiatric disturbances (by a general practitioner). Frequencies of psychiatric disturbances were different in men and women: 63.4% of the women in this study showed some type of psychiatric disturbance versus 36.6% of men (p=0.012). The majority of the diagnosis were mood disturbances, mainly depression associated or not with anxious disturbances. Mean age of psychiatric disturbance patients was 47.1 years versus 59.3 years in the patients without psychiatric disturbances (p=0.0049), showing the presence of psychiatric disturbances in younger patients. Other factors as systolic arterial blood pressure, diastolic arterial blood pressure and body mass index did not show any differences associated with psychiatric disturbance. We conclude that there is a great co-morbidity between high complexity hospitals hypertensive patients and that this type of disturbance is more frequent in women and in younger patients.
