This project will evaluate the clinical and cost effectiveness of a novel, multidisciplinary approach to identify and treat pre-clinical cardiac dysfunction (PCCD) in asymptomatic hypertensive patients identified in a single center urban emergency department. Premature onset of pressure-related cardiac complications of hypertension (especially heart failure) has important implications for long-term survival, quality of life and healthcare costs. This project will target patients who have already developed pressure-related cardiac structural abnormalities yet remain symptom free. These individuals are at tremendous risk for progression to clinically overt heart failure and its associated consequences. We hypothesize that detection and treatment of patients with hypertension who have pre-clinical structural cardiac damage will enable forestallment of the disease process and offer the opportunity to reduce the burden of cardiac morbidity associated with hypertension. This project will implement a program to prospectively identify PCCD (using echocardiography) and provide treatment. At present, the optimal blood pressure goal for patients with PCCD is unknown so this study will randomize patients to 2 levels of blood pressure control: "normal", which is consistent with current national guidelines and "intensive", which will aim for a markedly lower blood pressure (< 120/80). Enrolled patients will receive active treatment and follow-up for 1 year. At the end of 1 year, we will evaluate: 1) the ability of this program to achieve blood pressure goals; 2) the cost effectiveness; and 3) the proportion in each blood pressure group who have evidence of disease regression on echocardiography.

Arms | Assigned Interventions |
---|---|
Treatment 1: Active Comparator
This arm will target a blood pressure of < 140/90 mmHg (or < 130/90 mmHg for diabetics or those with chronic kidney disease) as indicated by the 7th Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure.

Behavioral: Exercise
Blood pressure (BP) target of < 140/90 mmHg (or < 130/80 mmHg for diabetics or with chronic kidney disease) as recommended by the 7th Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC 7). BP control efforts will be open-label and will include a combination of recommended life-style modifications (i.e., exercise, weight loss, low sodium diet, smoking cessation), and pharmaceutical therapy based on JNC 7 protocol driven guidelines with the following adaptations: 1) use of a diuretic that is appropriate to renal function (eGFR< 40 ml/min/1.73 m2: a loop diuretic; eGFR> 40 ml/min/1.73 m2: a thiazide); 2) use of automated reminders if BP exceeds target for > 4 weeks without a medication titration; 3) use of a second diuretic when taking 4 or more anti-hypertensives without adequate achievement of BP target level; and 4) automated alerts to study personnel for potential drug interactions.
Behavioral: Weight Loss
Blood pressure (BP) target of < 140/90 mmHg (or < 130/80 mmHg for diabetics or with chronic kidney disease) as recommended by the 7th Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC 7). BP control efforts will be open-label and will include a combination of recommended life-style modifications (i.e., exercise, weight loss, low sodium diet, smoking cessation), and pharmaceutical therapy based on JNC 7 protocol driven guidelines with the following adaptations: 1) use of a diuretic that is appropriate to renal function (eGFR< 40 ml/min/1.73 m2: a loop diuretic; eGFR> 40 ml/min/1.73 m2: a thiazide); 2) use of automated reminders if BP exceeds target for > 4 weeks without a medication titration; 3) use of a second diuretic when taking 4 or more anti-hypertensives without adequate achievement of BP target level; and 4) automated alerts to study personnel for potential drug interactions.
Behavioral: Low Sodium Diet
