Yet, whether invasive pneumococcal disease (IPD) increases the risk of AMI remains unclear. We examined whether laboratory-confirmed IPD was associated with the risk of AMI. Methods We conducted a self-controlled case series analysis among adult Tennessee residents with evidence of a first AM I hospitalization (2003-2019). Patient follow-up started 1 year prior to the earliest AMI and continued through the date of death, 1 year after AMI or end of study (12/2019). Periods for AMI assessment included the 7 to 1 days before IPD-specimen collection (pre IPD detection), day 0 through day 7 after IPD-specimen collection (current IPD), the 8 to 28 days after IPD-specimen collection (post IPD), and a control period (all other follow-up time). We used conditional Poisson regression to calculate incidence rate ratios and 95% confidence intervals (CI) for each risk period compared to control periods using within-person comparisons. Results We studied 324 patients hospitalized for AMI with a laboratory-confirmed IPD within 1 year before or after the AMI hospitalization. The incidence of AMI was significantly higher during the pre-IPD detection period (IRR:10.29; CI:6.33-16.73) and current IPD (IRR: 92.95; CI:72.17-119.71) periods, but non-significantly elevated in the post -IPD risk period (IRR: 1.83; CI:0.86-3.91) compared to control periods. An elevated AMI incidence was also observed in the post-IPD control period (29 to 364 days after IPD) [IRR: 2.95; CI:2.01-4.32]. Conclusions Hospitalizations with AMI were strongly associated with laboratory-confirmed IPD. View on Web
