All patients hospitalized with MI between 2018 and 2022 who underwent coronary angiography were included. For each patient, sociodemographic data, cardiovascular risk factors and history, and clinical and paraclinical presentation were collected at admission. In\u2010hospital outcomes, including major adverse cardiovascular events and mortality, were reported. Among 541 consecutive patients hospitalized with MI, 441 met the definition of type 1 MI or T2MI. T2MI accounted for 14.1% of cases. Patients with T2MI showed a trend toward slightly younger age (54 versus 58\u2009years,\n              <jats:italic toggle=\"no\">P<\/jats:italic>\n              =0.09). Patients with T2MI seemed to have less severe coronary artery disease, with less frequent multivessel disease (\n              <jats:italic toggle=\"no\">P<\/jats:italic>\n              &lt;0.001). Main triggering factors for T2MI were coronary embolism (24.2%), severe hypertension with or without left ventricular hypertrophy (22.6%), and tachyarrhythmia (16.1%).\n            <\/jats:p>\n            <jats:p xml:lang=\"en\">In\u2010hospital event rates were low in both MI types. Although the difference was nonsignificant, death rates for patients with type 1 MI tended to be higher than for patients with T2MI, as well as occurrence of major adverse cardiovascular events.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec id=\"jah39887-sec-0003\" xml:lang=\"en\">\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p xml:lang=\"en\">Our study revealed disparities in clinical characteristics, angiographic features, cause, and in\u2010hospital outcomes in T2MI in our population compared with Western populations.
