ALLHAT Heart Failure With Preserved And Impaired Systolic Left Ventricular Function In ALLHAT JB Kostis, B Davis, L Simpson, H Black, W Cushman, P Einhorn, M Farber, C Ford, D Levy, B Massie, S Nawaz For The ALLHAT Collaborative Research Group
ALLHAT AntihypertensiveTrial Design • Randomized, double-blind, multi-center clinical trial • Determine whether occurrence of fatal CHD or nonfatal MI is lower for high-risk hypertensive patients treated with newer agents (CCB, ACEI, alpha-blocker) compared with a diuretic • 42,418 high-risk hypertensive patients ≥ 55 years
ALLHAT Randomized Design of ALLHAT BP Trial 42,418 High-risk hypertensive patients Consent / Randomize Amlodipine Chlorthalidone Doxazosin Lisinopril Follow until death or end of study (4-8 years, mean 4.9 years)
ALLHAT Rationale for the Heart Failure Validation Study: Background • Early termination of the doxazosin arm February 2000, due to: • 25% higher risk of CVD events in doxazosin compared to chlorthalidone, mostly driven by two-fold increase in HF • a very low probability of finding a significant difference for the primary outcome by the scheduled trial end • Higher risk of HF in amlodipine and lisinopril arms compared with chlorthalidone • ALLHAT DSMB recommended that this study be done
ALLHAT Heart Failure Validation Study: Design and Methods • Protocol developed in collaboration with heart failure experts. • Additional documentation collected for all hospitalized heart failure events. • Documentation reviewed by cardiology fellows (blinded to treatment assignment), for signs, symptoms, past history, concomitant conditions, procedures, treatments. • Analyses performed using computer algorithm to determine whether each case met ALLHAT or Framingham criteria.
HF With Preserved And Impaired Systolic Left Ventricular Function ALLHAT Introduction • Heart failure developing in patients with hypertension is associated either with preserved or with impaired left ventricular systolic function. • ALLHAT provides the to examine occurrence and differences in symptoms, signs and case fatality of heart failure with preserved or impaired left ventricular systolic function.
ALLHAT HF With Preserved And Impaired Systolic Left Ventricular Function Methods • To verify the heart failure outcomes of ALLHAT, all available hospitalized heart failure events reported by ALLHAT Investigators were systematically reviewed. • Estimate of left ventricular ejection fraction by contrast ventriculography, echocardiography or radionuclide study was available in 928 (66%) of 1,300 first hospitalized heart failure events meeting ALLHAT criteria.

HF With Preserved And Impaired Systolic Left Ventricular Function ALLHAT Conclusions • Heart Failure with preserved left ventricular systolic function is common in treated patients with hypertension (compared to heart failure with impaired systolic function). • Heart Failure with preserved left ventricular systolic function is associated with more edema while heart failure with impaired left ventricular systolic function is associated with signs of ventricular dilatation. • Heart Failure with preserved left ventricular systolic function is associated with lower case fatality (than heart failure with impaired systolic function).
