  abstract = {{O}bjectives: {T}here are concerns about the potential effect of social distancing used to control {COVID}-19 on the incidence of cardiovascular diseases ({CVD}).{S}tudy design: {R}etrospective cohort study.{M}ethods: {W}e examined the association between lockdown and {CVD} incidence in a {Z}ero-{COVID} country, {N}ew {C}aledonia. {I}nclusion criteria were defined by a positive troponin sample during hospitalization. {T}he study period lasted for 2 months, starting {M}arch 20, 2020 (strict lockdown: first month; loose lockdown: second month) compared with the same period of the three previous years to calculate incidence ratio ({IR}). {D}emographic characteristics and main {CVD} diagnoses were collected. {T}he primary endpoint was the change in incidence of hospital admission with {CVD} during lockdown compared with the historical counterpart. {T}he secondary endpoint included influence of strict lockdown, change in incidence of the primary endpoint by disease, and outcome incidences (intubation or death) analyzed with inverse probability weighting method.{R}esults: {A} total of 1215 patients were included: 264 in 2020 vs 317 (average of the historical period). {CVD} hospitalizations were reduced during strict lockdown ({IR} 0.71 [0.58-0.88]), but not during loose lock -down ({IR} 0.94 [0.78-1.12]). {T}he incidence of acute coronary syndromes was similar in both periods. {T}he incidence of acute decompensated heart failure was reduced during strict lockdown ({IR} 0.42 [0.24-0.73]), followed by a rebound ({IR} 1.42 [1-1.98]). {T}here was no association between lockdown and short-term outcomes.{C}onclusions: {O}ur study showed that lockdown was associated with a striking reduction in {CVD} hospi-talizations, independently from viral spread, and a rebound of acute decompensated heart failure hos-pitalizations during looser lockdown.(c) 2023 {T}he {R}oyal {S}ociety for {P}ublic {H}ealth. {P}ublished by {E}lsevier {L}td. {A}ll rights reserved.},
