Validation of prognostic value of the hemodynamic gain index in different groups of patients undergoing exercise stress testing.

ABSTRACT:

Background

Recently, the hemodynamic gain index (HGI) has shown to be a strong independent predictor of all-cause mortality and associated with metabolic equivalents (METs) in a cohort of male patients. However, the prognostic implications of the HGI have never been externally validated with subgroup analyses based on gender, body mass index (BMI) of 35 kg/m², history of heart failure (HF), coronary artery disease (CAD) and beta-blocker use.

Methods

We identified 126,356 consecutive patients undergoing treadmill exercise testing between January 1st, 1991 and February 27th, 2015. HGI was calculated using the formula: [(SBP_peak × HR_peak) - (SBP_rest × HR_rest)] / (SBP_rest × HR_rest). Cox regression model
