Incident Heart Failure in Patients With Coronary Artery Disease Undergoing Percutaneous Coronary Intervention

Background: The contemporary incidence of heart failure (HF) in patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI) remains unclear. This prospective cohort study was designed to study the incidence and predictors of new-onset HF in CAD patients after PCI (ChiCTR1900023033). Methods: From January 2014 to December 2018, 3910 CAD patients without HF history undergoing PCI were prospectively enrolled. Demographics, medical history, cardiovascular risk factors, cardiac parameters and medication data were collected at baseline. Multivariable adjusted competing-risks regression analysis was performed to examine the predictors of incident HF. Results: After a median follow-up of 63 months, 497 patients (12.7%) reached the primary endpoint of new-onset HF, of which 179, 110 and 208 patients (36.0%, 22.1% and 41.9%) were diagnosed as having HF with reduced ejection fraction (EF) (HFrEF), HF with mid-range EF (HFmrEF) and HF with preserved EF (HFpEF), respectively. Higher B-type natriuretic peptide (BNP) or E/e’ level, lower estimated glomerular filtration rate (eGFR) level and atrial fibrillation were the independent risk factors of new-onset HF. Gender (male) and angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker (ACEI/ARB) prescription were the negative predictors of new-onset HF. Moreover, it was indicated that long-term ACEI/ARB therapy, instead of beta-blockers use, was linked to lower risks of all three HF subtypes (HFrEF, HFmrEF and HFpEF) development. Conclusions: This prospective longitudinal cohort study shows that the predominant subtype of HF after PCI is HFpEF and ACEI/ARB therapy is accompanied with reduced risks of incident HF across three subtypes.
