MedicalResearch.com Interview with: Prof. Michele Emdin, MD, PhD, FESC Associate Professor of Cardiovascular Medicine Director, Cardiology & Cardiovascular Medicine Division Fondazione Toscana Gabriele Monasterio per la Ricerca Medica e di Sanità Pubblica CNR-Regione Toscana with the collaboration of Dr. Alberto Aimo, MD Institute of Life Sciences Scuola Superiore Sant'Anna - Sant'Anna School of Advanced Studies Pisa, Italy MedicalResearch.com: What is the background for these meta-analyses? Response: Soluble suppression of tumorigenicity 2 (sST2) is a novel and promising biomarker of heart failure (HF). It has been extensively studied in both stable chronic (CHF) and acute HF (AHF), demonstrating substantial potential as a predictor of prognosis in both settings (Dieplinger et al., 2015). An International Consensus Panel (Januzzi et al., 2015) and latest American College of Cardiology Foundation/American Heart Association (ACCF/AHA) guidelines (Yancy et al., 2013) support the use of sST2 assay for risk stratification in both CHF and AHF patients. By contrast, European Society of Cardiology guidelines do not provide specific recommendations on sST2 (Ponikowski et al., 2016). Because of ambiguity due to discordant conclusions and to the absence of a thorough revision of the literature and of rigorous meta-analyses of published studies up-to-date, we felt it worthwhile to carefully examine and meta-analyze evidence supporting measurement of sST2, in order to assess the prognostic role of this biomarker in CHF and AHF. Most of the groups originally publishing on the topic all over the world and representing the Gotha of clinical research on cardiovascular biomarker, accepted to directly contribute allowing the main Authors to achieve novel information by a guided statistical reappraisal, The final results furnish clinically significant support to the use of sST2 as a risk stratification tool either in the acute or in the chronic heart failure setting.

MedicalResearch.com: Orly Vardeny, PharmD, MS Associate Professor of Pharmacy and Medicine University of Wisconsin-Madison MedicalResearch.com What are the main findings of the study? Answer: We performed a post-hoc analysis of the RALES study to assess rates of hyperkalemia and hypokalemia among African American (AA) and non-AA study participants, and examined clinical outcomes by race. We found that AA had less overall increases in potassium compared to non-AA, and exhibited less hyperkalemia with spironolactone. AA subjects were also found to have higher rates of hypokalemia, even among those randomized to spironolactone. Moreover, AA participants appeared to derive less clinical benefit from spironolactone. While non-AA demonstrated reduced risk for death and the combined endpoint of death or heart failure hospitalizations when randomized to spironolactone, African Americans did not derive benefit, and the risk of these outcomes were not different between spironolactone and placebo among AA.

MedicalResearch.com Interview with: Andrew Brenyo MD Electrophysiologist Greenville University Health System Greenville SC MedicalResearch.com: What are the main findings of the study? Dr. Brenyo: We found that BNP values at the time of CRT implant and during follow up predict response to CRT and subsequent risk of heart failure admission and death. BNP at implant and at subsequent times was strongly correlated with echocardiographic response to CRT-D along with predicting clinical outcome. (more…)
