"Every day, Americans are dying from cardiovascular disease that we know how to prevent and treat — and too often the barrier isn't the medicine; it's access to a clinician who can guide the care," ADVOCATE Program Manager Dr. Haider Warraich, a practicing cardiologist, said in a statement. ARPA-H said the program could generate an estimated $28 billion in annual cost savings across the heart failure population and reduce preventable hospitalizations. Nearly half of U.S. counties have no cardiologist, the agency said.
