Association of the get with the guidelines heart failure risk score with mortality in patients undergoing transcatheter edge-to-edge mitral valve repair

Abstract

Abstract Background Reliable risk scores in patients undergoing transcatheter edge-to-edge mitral valve repair (TMVR) are lacking. Heart failure is common in these patients, and risk scores derived from heart failure populations might help stratify TMVR patients. Methods Consecutive patients from three Heart Centers undergoing TMVR were enrolled to investigate the association of the “Get with the Guidelines Heart Failure Risk Score” (comprising the variables systolic blood pressure, urea nitrogen, blood sodium, age, heart rate, race, history of COPD) with all-cause mortality. Results Among 815 patients with available data 177 patients died during a mean follow-up time of 419 days. Estimated one-year mortality by quartiles of the score (0–37; 38–42, 43–47 and more than 47 points) was 6%, 10%, 23% and 30%, respectively (p<0.001). Every increase of one score point was associated with a 9% increase in the hazard of mortality (95% CI 1.06–1.11%, p<0.001). The score was associated with long-term mortality independently of left ventricular ejection fraction, renal function and LogEuroscore, and was equally predictive in primary and secondary mitral regurgitation. Conclusion The “Get with the Guidelines Heart Failure Risk Score” showed a strong association with mortality in patients undergoing TMVR with additive information beyond traditional risk factors. Given the routinely available variables included in this score, application is easy and broadly possible. Funding Acknowledgement Type of funding source: None
