All participants should have a follow-up visit within 7-14 days of hospital discharge. Heart rate and systolic blood pressure will be assessed at this clinical visit. For participants randomized to predischarge initiation of ivabradine and on ivabradine 5mg BID, the heart rate may be used to adjust the dose the dose to 2.5mg BID or 7.5mg BID. For participants randomized to usual care, ivabradine may be initiated at the provider's discretion. All participants will have a second follow-up study visit 6 weeks (42 +/- 14 days) post-discharge. Heart rate, systolic blood pressure and quality of life (KCCQ and PGA) will be assessed. For participants already taking ivabradine in either treatment group, the heart rate may again be used to adjust the dose of ivabradine. For participants not yet receiving ivabradine, it may be initiated at the provider's discretion. All participants will receive a 90 (+/-7) day post-discharge phone call by site to assess for event status and tolerability of ivabradine. All participants will have a final study visit at 180 (+/-14) days post-discharge. Heart rate, systolic blood pressure and quality of life (KCCQ and PGA) will be assessed. The attending physician may initiate ivabradine per usual care clinical practice.
