Marchand et al. finds (meta-analysis of self-controlled case series) in tangential & direct support of Ladapo et al., an increased risk of cardiac related mortality; HR =1.06, 95% CI 1.02-1.11, p=.007

the pooled HR suggests that COVID-19 vaccination is associated with an increased risk of cardiac-related mortality (HR = 1.06, 95% CI [1.02, 1.11], p = .007). Subgroup, males greater cardiac deaths

‘Three SCCS were located, totaling approximately 750,000 patients…Regarding cardiac-related mortality, the pooled HR suggests that COVID-19 vaccination is associated with an increased risk of cardiac-related mortality (HR = 1.06, 95% CI [1.02, 1.11], p = .007). Subgroup analysis showed that the male gender is significantly associated with an increased incidence of cardiac-related deaths (HR = 1.09, 95% CI [1.02, 1.15], p = .006). In conclusion, COVID-19 vaccination may be associated with a small increase in cardiac-related mortality, especially among males.’
