Sex Differences in Cardiac Risk Factors, Perceived Risk, and Health Care Provider Discussion of Risk and Risk Modification Among Young Patients With Acute Myocardial Infarction The VIRGO Study

AbstractBackgroundDifferences between sexes in cardiac risk factors, perceptions of cardiac risk, and health care provider discussions about risk among young patients with acute myocardial infarction (AMI) are not well studied.ObjectivesThis study compared cardiac risk factor prevalence, risk perceptions, and health care provider feedback on heart disease and risk modification between young women and men hospitalized with AMI.MethodsWe studied 3,501 AMI patients age 18 to 55 years enrolled in the VIRGO (Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients) study in U.S. and Spanish hospitals between August 2008 and January 2012, comparing the prevalence of 5 cardiac risk factors by sex. Modified Poisson regression was used to assess sex differences in self-perceived heart disease risk and self-reported provider discussions of risk and modification.ResultsNearly all patients (98%) had ≥1 risk factor, and 64% had ≥3. Only 53% of patients considered themselves at risk for heart disease, and even fewer reported being told they were at risk (46%) or that their health care provider had discussed heart disease and risk modification (49%). Women were less likely than men to be told they were at risk (relative risk: 0.89; 95% confidence interval: 0.84 to 0.96) or to have a provider discuss risk modification (relative risk: 0.84; 95% confidence interval: 0.79 to 0.89). There was no difference between women and men for self-perceived risk.ConclusionsDespite having significant cardiac risk factors, only one-half of young AMI patients believed they were at risk for heart disease before their event. Even fewer discussed their risks or risk modification with their health care providers; this issue was more pronounced among women
