High prevalence of preclinical heart failure in the population

According to a recent study of Framingham Study participants, nearly 60 percent of people have prevalent preclinical heart failure (HF) stages A and B. Heart failure occurs when the heart muscle is weakened and cannot pump enough blood to meet the body's needs for blood and oxygen. In addition, individuals with stage B HF had greater circulating concentrations of cardiac stress biomarkers levels, putting them at increased risk for death.
