Introduction:
Many patients with heart failure (HF) suffer from coronary artery
disease (CAD) simultaneously, with estimated prevalence ranging from
50% to 65% [1]. Recent data indicate that CAD has become the most
common cause of HF, surpassing hypertension and valvular heart disease
[2]. Moreover, CAD substantially increases the risk for developing
HF, whether it is with reduced or preserved ejection fraction [3].
Despite the somewhat limited evidence regarding the risk of all-cause
and cardiovascular mortality, 2021 Expert Consensus Pathway for
Optimization of Heart Failure Treatment has recommended coronary
revascularization in appropriate patients [4]. Regardless of whether
percutaneous coronary intervention (PCI) or coronary artery bypass
surgery (CABG) is preferred option, patients with complex coronary
occlusions are increasingly not surgical candidates and are referred for
hemodynamic-supported complex percutaneous revascularization.
