REN and heart failure: An unpublished comparison of RACE and RACE-II (Fig. 3) showed that over the 10 years between those two studies sustained rather than interrupted anticoagulation as well as management of high blood pressure and heart failure with renin-angiotensin system inhibition had improved prognosis: less stroke and bleeding, fewer admissions for myocardial infarction or heart failure, and fewer severe side effects of drugs.
