Cardiovascular disease (CVD) is the most common cause of mortality in the United States. Women have unique risk factors for CVD, including pregnancy, hormones, autoimmune disorders, and psychological stress. Most risk calculators underestimate the risk of CVD in women; therefore, it is essential that physicians have a heightened awareness of risk-enhancing factors. A thorough history of adverse pregnancy conditions, hormonal factors, autoimmune diseases, and psychological stress, including adverse social determinants of health, should be documented in the electronic health record. A risk assessment using the Atherosclerotic Cardiovascular Disease Risk Calculator should be routinely performed, and those with borderline (5% to less than 7.5%) and intermediate (7.5% to less than 20%) risk should undergo lifestyle modification counseling and shared decision-making regarding the initiation of a statin, aspirin, or antihypertensive therapy. Women with gestational diabetes mellitus should be screened at four to 12 weeks postpartum with a two-hour oral glucose tolerance test, and, if normal, the test should be repeated every one to three years. Women with hypertensive disorders of pregnancy should be assessed within three months of delivery, and CVD risk assessment should occur annually thereafter. Because women with a history of adverse pregnancy conditions have higher rates of traditional CVD risk factors that emerge at younger ages, earlier and more frequent monitoring should be considered. Optimizing management of mood disorders, traditional CVD risk factors, and autoimmune diseases and considering the effects of social determinants of health are essential. Lifestyle modification counseling should include guidance to adhere to a plant-based diet that is mostly vegetables, fruits, legumes, nuts, whole grains, and fish; 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity exercise weekly; and tobacco cessation.
Although cardiovascular disease (CVD) remains the most common cause of death in the United States, CVD mortality rates have decreased over the past 40 years.1 The greatest gains were in men and women older than 65 years. However, women younger than 55 years experienced the smallest decline in mortality and an increase in hospitalizations for acute myocardial infarction from 2000 to 2009.2 Women are largely underrepresented in research studies, and data on prevention strategies are derived from studies in men, possibly explaining why the decline in the rate of CVD mortality in men is greater than that in women.1,3 Although terminology is not consistent and is used interchangeably, most studies refer to the term woman as sex assigned at birth and compared women with men.3 When counseling patients, physicians recognize traditional CVD risk factors but may be uncertain about how to account for the unique stages across a woman’s life span that can increase CVD risk, including factors related to pregnancy, hormones, autoimmune disorders, psychological stress, and social determinants of health. These risk factors are summarized in Table 1.4–23
WHAT’S NEW ON THIS TOPIC

| In a systematic review including more than 3 million women, a history of gestational diabetes mellitus doubled the risk of cardiovascular events in the first 10 years after pregnancy, with an NNH of 200. |
| Women who had preeclampsia during pregnancy have a higher risk of future hypertension (NNH = 6 over 11 years), ischemic heart disease (NNH = 333 over 12 years), and stroke (NNH = 666 over 10 years) than those who did not. |
| Compared with menopause onset at 55 years or older, cardiovascular events occur more often in those with earlier onset, with 2.6 events per 1,000 person-years for onset between 45 and 49 years of age, 3 events per 1,000 person-years for onset between 40 and 45 years of age, and 4 events per 1,000 person-years for onset before 40 years of age. [corrected] The median time from menopause to development of cardiovascular disease is 12 years. |
| In an 18-year longitudinal cohort study, women diagnosed with depression at enrollment had double the incidence of coronary heart disease after adjusting for traditional risk factors. |
