Wong et al examined the prevalence and adequacy of treatment and control of hypertension (HTN) in persons with cardiovascular comorbidities in 4646 adults (projected to 192 million) in the US National Health and Nutrition Examination Survey (2003-2004). Among persons with cardiovascular comorbidities, prevalence of HTN ranged from 52% to 82%, compared with 23% in those without these conditions. Despite HTN treatment rates for patients with diabetes, stroke, heart failure, and coronary artery disease being higher (83%-89%) compared with those without these conditions (66.5%), control rates on treatment remained poor (35%-62%). Isolated systolic HTN was the most common hypertensive subtype in those with cardiovascular comorbidities. Nearly three-fourths of adults with cardiovascular comorbidities have HTN, which further compromises their already high cardiovascular disease risk.
