Why the study?
Does elevated resting heart rate predict incident heart failure and left ventricular dysfunction in an asymptomatic multi-ethnic population?
Does elevated resting heart rate predict incident heart failure and left ventricular dysfunction in an asymptomatic multi-ethnic population?
Elevated resting heart rate is an independent predictor of incident heart failure and progressive left ventricular dysfunction in asymptomatic individuals.
No takes yet. Share an insight, caveat, or question.
May flag higher HF risk in asymptomatic adults; extends observational data but remains hypothesis-generating without randomized confirmation.
Opdahl et al. (2014) studied this question.
