Promising Practices Related To The Prevention, Control and Treatment of Hypertension David J. Hyman, MD, MPH Professor of Medicine and Family & Community Medicine Baylor College of Medicine President elect - Texas Chapter of the American Society of Hypertension
Problems Hypertension is an extremely important Risk factor for heart disease, stroke, Renal failure, CHF and all the complications of diabetes Population BP has stopped going down About 35% of people with hypertension are still unaware of it About 35% of people being treated for hypertension are not controlled to target
Non-HispanicMexican- African- whiteAmerican American 27.4% 25.1 % 40.5% Age Standardized Prevalence of Hypertension in the United States National Health and Nutrition Survey (NHANES) (1999-2002)
Prevalence of Hypertension in the United States* *Based on NHANES 19992000 data. Hypertension is defined as blood pressure 140/90 mmHg or antihypertensive treatment. Low reliability due to large relative error. Fields et al. Hypertension. 2004:44;398-404. Hypertension Prevalence Age
% of Treated Controlled 64 Hypertension Control in U.S. - NHANES Ong, Hypertension 2007 % of Treated Controlled 30 % of Treated Controlled 65 % of Treated Controlled 43 % of Treated Controlled 51
Primary Prevention of Hypertension via food supply sodium reduction: A growing international trend that TEXAS should join 1.3 gm average daily decrease will prevent 5mm/HG rise in BP with age and save 150,000 lives year - Most sodium is in processed food - Individual action is extremely difficult - Commercial alternatives exist - Food supply interventions are occurring around the world -Dickinson, AMA council of scientific affairs, archives IM 2007
England Department of Health and Food standards agency goal 2.4 gm sodium by 2010 50 food manufactures have signed on and begun to reduce Ireland Pressuring food industry New Zealand / Australia Strict labeling Industry pressure to reduce sodium has reduced Sodium in breads, cereals, margarine France Goal 20% reduction in 5 years Finland National focus since 1970s Sodium decrease from 4700 to 3300 Population decrease in blood pressure International Efforts
Of the unaware hypertensives… Mexican Americans are very over represented But 90 % of Unaware have insurance 80% have a usual source of care 75% had a BP measurement in the last year 96% had a BP measurement in the last 4 years Mean age 58 Mean BP 148/83 Hyman NEJM 2001
Implication: New screening programs needed Hispanics Low utilizers Education programs needed for health providers and public on appropriate reaction to mild BP elevations New technologies and paradigms for BP measurement may be needed.
Improving control in treated patients Continue public and physician education Appreciate limits on scientific data on achieving goals Educate on the availability of low cost drugs
Hypertension Treatment by Drug Class CCB s ß-Blocker ACE Inhibitors Diuretics ARB s IMS Health NDTI, 1978-2002
Cost of market leaders Norvasc $84 month Valsartan $74 month What you can get for $ 4 per month from Walmart (web 9/07) ACE Benezepril 10-40 Lisinopril 10-20 B blocker Metoprolol (BID) Atenelol Carvedilol (BID) Thiazides* Clonidine* Lovastatin 10,20 Pravastatin 10-40
If BP drugs are cheap… Big pharma cant make any $ on BP Drugs… If big pharma controls the flow of medical information… and big pharma looses interest in Hypertension… The public health community will have to keep blood pressure control on the agenda by our selves!! The population will suffer if we dont.
