What Is Global CV Risk? Treating hypertension to goal is good Addressing all CV risk factors is better Achieve optimal BP level Avoid CV and renal morbidity and mortality Chobanian AV et al, for the NHBPEPCC.

Factors Contributing to Poor Adherence Lack of understanding Dementia/senility Side effects Lack of discharge planning Cost Lack of symptoms Complexity of Rx regimen Poor mobility Little or no support system Modified from: Vermeire E, et al. J Clin Pharm and Ther. 2001;26:331-342; Cheng JWM, et al. Pharmacotherapy. 2001;21:828-841.

Practical Tips to Improve Adherence Talk to your patient Explain the condition and why therapy is important Ask about adherence Involve the patient as a partner in treatment Provide clear written and oral instructions Tailor the regimen to the patient’s lifestyle and needs Use motivational interviewing techniques Look for: Ways to approach patients based on individual attitudes Allies in patient care—family, friends Ways to simplify the regimen Refill dates (no refill = no adherence) Ockene IS et al. J Am Coll Cardiol. 2002;40:630-640.
55
Practical Tips to Improve Adherence Use systematic approaches Disease management programs Periodic review of electronic medical records or manual chart audits Group/shared medical appointments offering care, education, social support Other techniques Follow-up (telephone/mail/e-mail) and reminder cards Signed agreements/contracts Self-monitoring tools (eg, tape measure, pedometer) Patient assistance programs Support when medication costs are a barrier Fonarow GC et al. Am J Cardiol. 2001;87:819-822; Ockene IS et al. J Am Coll Cardiol. 2002;40: 630-640; NCEP ATP III. September 2002. NIH publication no. 02-5215; Pfizer Helpful Answers Web site.

Summary: The Case for Global CV Risk Management CV disease remains the leading cause of death in both men and women in the United States Data from the Framingham Heart Study have demonstrated clustering of risk factors—and that risk of death from CHD and stroke increases further with each added risk factor Hypertension, a pivotal risk factor for CV disease, should prompt the search for the presence of additional risk factors Recent clinical trials have provided evidence supporting a standard of care for the management of global CV risk

PCE Takeaways
64
1. Patients with hypertension often present with multiple cardiac risk factors 2. Be vigilant in your investigation of all clinical indicators 3. Creatively address patient adherence; not everyone responds to the same interventions 4. Clinical inertia is the enemy—don't settle for "close enough"
65
