This study aimed to examine the associations of daily air pressure and APCN with the onset of AMI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p xml:lang=\"en\">A time\u2010stratified case\u2010crossover study was conducted using data from 473\u2009599 patients with AMI recorded in the Beijing Cardiovascular Disease Surveillance System between 2007 and 2021. The associations between daily air pressure and APCN with AMI onset were assessed using conditional logistic regression and distributed lag\u2010nonlinear models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">Both low and high air pressure were significantly associated with an increased risk of AMI, with odds ratios (ORs) of 1.06 (95% CI, 1.01\u20131.12) and 1.16 (95% CI, 1.11\u20131.20), respectively. Patients with comorbidities of heart failure and hypertension exhibited increased vulnerability to extremely high air pressure. Moreover, the effects of both extremely low and high air pressure were amplified on days with higher levels of particulate matter &lt;2.5 \u03bcm in aerodynamic diameter and temperature. A negative APCN was associated with an elevated risk of AMI, with an OR of 1.19 (95% CI, 1.12\u20131.25) for an extremely negative APCN (\u22129.74 hPa) compared with no change in air pressure. Negative APCN risk was notably higher in older adults, women, and individuals with hypertension or diabetes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n
