Prior studies found reduced incidences of cardiovascular diagnoses and treatments in the initial phase of the COVID-19 pandemic. However, these studies included a limited number of outcomes and did not consider pre-pandemic trends. This study aimed to describe trends in the incidence of cardiovascular diagnoses and treatments over the years 2012-2021 in Israel and to compare the two years of the COVID-19 period with the preceding 8 years. In this retrospective, population-based study, carried out within Clalit Health Services, the incidence rates of cardiovascular outcomes were calculated for individuals aged ≥ 25 (~2.7 million adults per year) during the first (Y1, 3/2020-2/2021) and second (Y2, 3/2021-2/2022) years of COVID-19 and the 8 years prior (3/2012-2/2020). Declines were observed in Y1 compared to 2019 in all diagnoses and treatments: STEMI (-16.3%; 95% CI: -16.6, -16.1), non-STEMI (-16.4%; -16.6, -16.2), AF (-14.1%; -14.2, -14.0), CHF (-7.8%; -7.9, -7.7), CVA (-5.0%; -5.0, -4.9), catheterization (-64.7%; -65.2, -64.2), CABG (-77.7%; -79.2, -76.2), ablation (-21.2%; -22.0, -20.4), pacemaker implantation (-39.3%; -40.7, -37.9), and defibrillator insertion (-12.5%; -13.1, -12.0). Compared with expected rates based on pre-pandemic trends, observed rates were within expected ranges (CHF, CVA, and ablation), less than expected (STEMI, non-STEMI, AF, catheterization, CABG, and pacemaker insertion), or more than expected (defibrillator insertion). In Y2, STEMI, catheterization, and CABG returned to expected rates; non-STEMI and AF were lower than expected; and CHF, CVA, ablation, and pacemaker and defibrillator implantations were higher than expected. Several cardiovascular diagnoses and treatment trends were interrupted by COVID-19. The long-term consequences of these changes should be considered by health policymakers.
