Background Hypertension is among the most common chronic condition in middle-aged and older adults. to $37,408 in older individuals with ISH. The incremental cost of the Homoharringtonine supplier 5 yr NNT was lower to treat older individuals in the very high CVD risk group relative to individuals in the lower CVD risk group, ranging from $456 to $15,511. Compared to the cost of the 5 yr NNT of additional commonly prescribed antihypertensive drugs, the cost of SHEP-based therapy is the least expensive. The incremental costs of the 5 yr NNT would be higher if additional agents were used, ranging from $6,372 to $38,667 to prevent one CVD event relative to SHEP-based drug therapy. Summary Antihypertensive therapy that is diuretic-based and that includes either low-dose reserpine or atenolol is an effective and relatively inexpensive strategy to prevent cardiovascular events in older adults with isolated systolic hypertension. Use of the diuretic-based therapy is the most cost-effective in individuals at high risk for developing cardiovascular disease. Background Hypertension is among the most common chronic conditions in middle-aged and older adults. Approximately 50 million People in america are currently diagnosed with this condition, and more than $18.7 billion is spent on hypertension management, including $3.8 billion for medications. Treatment of hypertension can significantly decrease the risk of developing CVD [2,3]. The SHEP and additional studies have shown the great potential of antihypertensive treatments to significantly reduce the quantity of cardiovascular events in elderly individuals [4-10]. This, in turn, may reduce the costs associated with this chronic condition. Based on the SHEP study, it is estimated that 24,000 strokes, 44,000 major cardiovascular events, and 84,000 admissions to the hospital could be prevented over a 5-yr period . Currently, primary care physicians can choose from several pharmacological agents to treat hypertension. The popular antihypertensive drug classes include diuretics, beta-blockers, angiotensin-converting enzyme (ACE) inhibitors, alpha-blockers, and calcium channel blockers. Selection of an evidence-based therapy with shown efficacy, security, and low cost has important economic implications. The purpose of this study was to: 1) assess cost of the SHEP-based antihypertensive treatment to prevent adverse events associated with CVD, including death, stroke, myocardial infarction, and heart failure; and 2) to compare cost of the SHEP-based treatment to the costs of additional popular antihypertensive agent treatments. Method The SHEP trial is definitely a randomized, double-blind, placebo-controlled medical trial sponsored from the National Heart, Lung, and Blood Institute and the National Institute on Ageing that tested the effectiveness of diuretic-based stepped-care antihypertensive drug treatment of isolated systolic hypertension (ISH) to prevent strokes . Study Population The study subjects consisted of community-dwelling men and women 60 years and older who experienced isolated systolic hypertension, defined as an average systolic blood pressure (SBP) 160 mm Hg and an average diastolic blood pressure (DBP) < 90 mm Hg over 2 baseline appointments. The primary endpoint of the trial was combined nonfatal and Homoharringtonine supplier fatal stroke over a 5-yr period. Secondary endpoints included nonfatal myocardial infarction (MI) plus Homoharringtonine supplier fatal coronary heart disease (CHD) and major cardiovascular disease (CVD) morbidity and mortality. A total of 2,365 and 2,371 individuals were randomized into the treatment and placebo group of the study respectively. Subjects who met the preliminary blood pressure (BP) eligibility criteria at the initial contact visit were referred to SHEP clinics for the baseline appointments. In the baseline appointments, subject's demographics, medical conditions, health behaviours, and cardiovascular risk factors were obtained. Methods of these measurements have been reported4. Fasting blood samples were analyzed at a central laboratory, including serum glucose, lipid levels, creatinine, uric acid, sodium, and potassium. Of the 4,736 SHEP participants, 4,189 were included in this analysis. The 547 participants were excluded either because of missing data concerning CVD risk factors (n = 283) or with earlier CHD or stroke (n = 264). Itgax These 547 excluded subjects had similar age, sex, race, and additional characteristics as those who were included in this analysis. Treatment A stepped-care treatment approach was used, with the goal for individuals with SBP >180 mm Hg to Homoharringtonine supplier reduce to Homoharringtonine supplier <160 mm Hg and for those with SBP between 160 and 179 mm Hg to have a reduction of at least 20 mm Hg. All participants were given chlorthalidone, 12.5 mg/d, or coordinating placebo (step 1 1 and dose 1 medication). Drug dosage (step 1 1 and dose 2 medication) was doubled, 25 mg/d, for participants failing to.
