Heart failure patients who live in communities affected by fracking are at increased risk for hospitalization, according to a study published in the Journal of the American College of Cardiology today. The study looked at the environmental exposure risk of thousands of heart failure patients across Pennsylvania. Heart failure is a lifelong condition that affects over 5.7 million Americans. Heart failure makes it harder for the heart to pump enough blood and oxygen to meet the body’s needs. The two main heart failure phenotypes, reduced ejection fraction (HFrEF) or preserved ejection fraction (HFpEF), can lead to worsening cardiac health and reduced blood flow to critical organs. In turn, heart failure patients are at higher risk for hospitalizations and death.
