Acute coronary syndrome (ACS) is the most common cause of heart failure (HF) world-wide. Primary percutaneous coronary intervention (PCI) has deeply improved short and long-term survival after ACS, but his impact on incidence of downstream heart failure still remains unclear and heart failure after ACS represents the major driver of late morbidity, mortality and healthcare cost.~Many predictors and determinant of heart failure after MI have been evaluated, however, to date, the optimal combination of parameters to predict heart failure after MI needs to be defined and very little is known about the prognostic markers in unstable angina setting~The aim of this retrospective study:~to show the incidence of heart failure after acute coronary artery syndrome, and the relation between the type of ACS and following incidence of HF.~to clarify which features could be routinely identified as prognostic markers. This study is a multi-center non-randomized, single-cohort retrospective study including consecutive patients with acute coronary syndrome treated by percutaneous coronary intervention between 2017 and 2019, without known previous heart failure (baseline EF > 40% and no medical therapy with loop diuretics), with at least 12 months of follow-up.~It is possible to anticipate that the main findings of the present study will fill fundamental knowledge gaps regarding incidence of heart failure following coronary events.~Among this, the study could suggest specific clinical and epidemiological features related to the risk of development of HF, leading to a better medical treatment and reducing risk for further hospitalizations.
