Prevalence and 1-year prognosis of transient heart failure following coronary revascularization.

Abstract：

:The occurrence of heart failure during the whole pre-discharge course of coronary revascularization, as far as its influence on subsequent prognosis, is poorly understood. The present study examined the effect of transient heart failure (THF) developing in the acute and rehabilitative phase on survival after coronary artery bypass graft surgery (CABG) and percutaneous coronary intervention (PCI). Patients in the Italian survey on cardiac rehabilitation and secondary prevention after cardiac revascularization (ICAROS) were analyzed for THF, the latter being defined either as signs and symptoms consistent with decompensation or cardiogenic shock. ICAROS was a prospective, multicenter registry of 1,262 consecutive patients discharged from 62 cardiac rehabilitation (CR) facilities, providing data on risk factors, lifestyle habits, drug treatments, and major cardiovascular events (MACE) during a 1-year follow-up. Records were linked to the official website of the Italian Association of Cardiovascular Prevention and Rehabilitation (GICR-IACPR). The overall prevalence of pre-discharge THF was 7.6%, with 69.8% of cases in acute wards, 22.9% during CR, and 7.3% in both settings. THF affected more frequently patients with chronic cardiac condition (42.7 vs. 30.6%; p < 0.05), age ≥75 years (33.3 vs. 23.1%; p < 0.005), COPD (19.8 vs. 12.3%; p < 0.05), and chronic kidney disease (17.7 vs. 7%; p < 0.001). After discharge, THF patients showed good maintenance rates of RAAS modulators (90.6%) and beta-blockers (83.3%), while statin therapy significantly decreased from 81.3 to 64.6% (p < 0.05). The pursuit of secondary prevention targets, as far as self-reported drug adherence, was not different among groups. Patients with THF had increased 1-year mortality (8.3 vs. 1.6%, p < 0.001). Moreover, THF independently predicted adverse outcome with OR for recurrent events (mainly further episodes of decompensation) of 2.4 (CI 1.4-4.3). Patients who experienced THF after coronary revascularization had increased post-discharge mortality and cardiovascular events. Hemodynamic instability, rather than recurrent myocardial ischemia, seems to be linked with worse prognosis.
