Overall, 14\u2009297 individuals (1.19 per 1000) were readmitted within 6\u2009months postpartum with cardiovascular SMM, of whom 5912 (41.4%) had a hypertensive diagnosis at delivery. Hypertensive diagnoses were associated with increased odds for 6 months postpartum cardiovascular SMM readmission (aOR 2.8 95% CI 2.7\u20133.0). Evaluating individual diagnoses, superimposed preeclampsia (aOR 4.3, 95% CI 3.8\u20134.8), chronic hypertension (aOR 3.2, 95% CI 2.9\u20133.5), preeclampsia without severe features (aOR 3.1, 95% CI 2.8\u20133.5), preeclampsia with severe features (aOR 3.0, 95% CI 2.7\u20133.3) and gestational hypertension (aOR 2.1, CI 1.9\u20132.3) were all associated with significantly higher odds for postpartum cardiovascular SMM readmission compared to the absence of hypertensive diagnoses. In ancillary analysis restricted to patients with hypertensive disorders, delivery &lt;\u200934\u2009weeks was associated with higher odds for 6\u2010month cardiovascular SMM postpartum readmission (aOR 1.4, 95% CI 1.2\u20131.6).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Hypertensive diagnoses were associated with significantly increased odds for 6\u2010month postpartum cardiovascular SMM readmission, with individual diagnoses demonstrating distinct odds. Among patients with hypertensive disorders, delivery &lt;\u200934\u2009weeks was particularly associated with increased odds. Hypertensive disorders are important risk factors for adverse cardio\u2010obstetric outcomes postpartum and represent important factors to identify patient risk and improve the quality of postpartum
