Background— Despite a recent American Heart Association (AHA) consensus statement emphasizing the importance of resistant hypertension, incidence and prognosis this condition are largely unknown. Methods Results— This retrospective cohort study in 2 integrated health plans included patients with incident hypertension whom treatment was begun between 2002 2006. Patients were followed up for development based on AHA criteria uncontrolled blood pressure despite use ≥3 antihypertensive...

Patients with resistant hypertension are at risk for poor outcomes. Medication adherence and intensification improve blood pressure (BP) control; however, little is known about these processes or their association outcomes in hypertension. This retrospective study included patients from 2002 to 2006 incident 2 health systems who developed uncontrolled BP despite ≥3 antihypertensive medications. Patterns of treatment, medication (percentage days covered), treatment (increase class dose) were...

Hypertension is an important cause of chronic kidney disease (CKD). Identifying risk factors for progression to CKD in patients with normal function and hypertension may help target therapies slow or prevent decline function. Our objective was identify development incident estimated GFR (eGFR) hypertensive patients.Cox proportional hazards models were used assess the relationship between (defined as eGFR <60 ml/min per 1.73 m(2)) potential from a registry patients.Of 43,305 meeting inclusion...
