We conducted an electronic search of the CDC WONDER Online Database with the most recent updates (Underlying Cause of Death, 2018–2021),4 which reports national mortality and population data stratified by ICD-10 codes. Information is based on death certificates for US residents, and mortality data are calculated from official death certificates, excluding nonresidents. Our basic query criteria included the IHD-specific ICD-10 code (I20-I25; Ischemic heart diseases), the year range (from 2018 to 2021), and the day of the week (from Monday to Sunday). A clear decrease in the death rate for IHD from Monday to Sunday was observed. Although this trend slightly failed to become statistically significant in one-way analysis ANOVA (F Statistic: 2.33; p = 0.070), the Pearson's correlation between mortality rate and day of the week was highly statistically significant (r = −0.838; p < 0.001). The Tukey HSD (post-hoc) test also revealed a statistically significant difference in the death rate between Monday and Sunday (p = 0.036). At the same time, all other interactions between days of the week did not reach statistical significance.

Abstract
We conducted an electronic search of the CDC WONDER Online Database with the most recent updates (Underlying Cause of Death, 2018–2021),4 which reports national mortality and population data stratified by ICD-10 codes. Information is based on death certificates for US residents, and mortality data are calculated from official death certificates, excluding nonresidents. Our basic query criteria included the IHD-specific ICD-10 code (I20-I25; Ischemic heart diseases), the year range (from 2018 to 2021), and the day of the week (from Monday to Sunday). A clear decrease in the death rate for IHD from Monday to Sunday was observed. Although this trend slightly failed to become statistically significant in one-way analysis ANOVA (F Statistic: 2.33; p = 0.070), the Pearson's correlation between mortality rate and day of the week was highly statistically significant (r = −0.838; p < 0.001). The Tukey HSD (post-hoc) test also revealed a statistically significant difference in the death rate between Monday and Sunday (p = 0.036). At the same time, all other interactions between days of the week did not reach statistical significance.
