Ninety-one cases had abnormal electrocardiogram (ECG) (91%), mainly with ST-T changes (77%). The average interventricular septum was 19.39 \u00b1 6.13 mm by echocardiography (21.75 \u00b1 5.86 mm for obstructive HCM and 18.73 \u00b1 6.08 mm for non-obstructive HCM). The main cardiac complications were maternal death (n = 2, 2%), heart failure (n = 7, 7%), and sustained ventricular tachyarrhythmia (n = 1, 1%). Cardiac complications occur commonly during the third trimester and postpartum period. Three independent risk factors to predict cardiac complications in pregnant women with HCM were obstructive HCM (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.036), New York Heart Association (NYHA) class \u2265II (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.022), and previous history of syncope (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.037).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>HCM increases the risk of maternal death, heart failure, and malignant arrhythmia.
