Abstract: 
OBJECTIVE: To identify markers for loss of control of hypertension. DESIGN: Questionnaire administered to patients who had been monitored for 18 months and had had their blood pressure (BP) measured many times. SETTING: Fifty family practices in southeastern Ontario. PARTICIPANTS: Three hundred eighty-five adults with essential hypertension that was initially stable and controlled by medication. MAIN OUTCOME MEASURES: Change in BP (from baseline to mean of three measurements over 18 months) and proportion of patients with BP exceeding threshold values at most follow-up visits. RESULTS: Higher income was associated with an increase in diastolic BP; poor adherence to medication regimens and higher life stress were associated with increases in systolic BP Stress also led to a twofold increase in risk of exceeding BP thresholds. Other factors under study were not related to loss of control. CONCLUSION: Adherence to medication regimens, higher income, and life stress were the only factors associated with elevated BP or loss of control in previously controlled hypertension
