Major Adverse Cardiovascular Events Following Coronary Artery Stenting by History of Hypertensive Disorder of Pregnancy.

BACKGROUND

A history of hypertensive disorders of pregnancy is associated with at least twice the risk of incident ischemic heart disease. Whether the long-term outcome following treatment with coronary artery stenting is associated to the history of hypertensive disorders of pregnancy is unknown.

METHODS AND RESULTS

We included 8364 women (age ≤65 years) undergoing first coronary artery stenting 2006 to 2022 following their first delivery in 1973 or later, linking nationwide data on percutaneous coronary intervention and delivery history. In total, 1122 women (13.4%) had a history of hypertensive disorders of pregnancy. The main outcome, a major adverse cardiovascular event, was defined as any incident myocardial infarction, ischemic heart disease, cardiac arrest, arrhythmias, angina pectoris, heart failure, cerebral infarction, or sudden death. During a median follow-up time of 5 years, 258 women with a history of hypertensive disorders of pregnancy had a major adverse cardiovascular event, compared with 1465 women without a history of hypertensive disorders of pregnancy (23% versus 20.2%,

CONCLUSIONS

Women with a history of hypertensive disorders of pregnancy have an increased risk of a major adverse cardiovascular event following coronary artery stenting compared with other parous women. A history of hypertensive disorders of pregnancy warrants further attention in the secondary prevention setting of coronary artery disease.
