Young women with acute myocardial infarction (AMI) have a worse prognosis than their male counterparts. We searched for differences in the electrocardiographic presentation of men and women in a large, contemporary registry of young adults with AMI that could help explain gender differences in outcomes. The qualifying electrocardiogram was blindly assessed by a central core lab in 3,354 patients (67% women) aged 18 to 55 years included in the Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients study. Compared with men, women did not have a different frequency of sinus rhythm, and they had shorter PR and QRS intervals and longer QTc intervals. Intraventricular conduction disturbances were not different among genders. Notably, women were more likely than men to have abnormal Q waves in anterior leads and a lower frequency of Q waves in other territories. ST-segment elevation myocardial infarction (STEMI) diagnosis was less frequent in women than in men (44.6% vs 55.1%, p < 0.001). Among patients with STEMI, women had less magnitude and extent of ST-segment elevation than men. In patients with non-STEMI, the frequency, magnitude, and extent of ST-segment depression were not different among genders, but women had anterior ST-segment depression less frequently and anterior negative T waves more frequently compared with men. These differences remained statistically significant after adjusting for baseline characteristics. In conclusion, there are significant gender differences in the electrocardiographic presentation of AMI among young patients. Further studies are warranted to evaluate their impact on gender-related differences in the management and outcomes of AMI., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Background: United States and European cardiovascular society guidelines recommend physicians counsel patients about resuming sexual activity after acute myocardial infarction (AMI), but little is known about patients' experience with counseling about sexual activity after AMI., Methods and Results: The prospective, longitudinal Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients (VIRGO) study, conducted at 127 hospitals in the United States and Spain, was designed, in part, to evaluate gender differences in baseline sexual activity, function, and patient experience with physician counseling about sexual activity after an AMI. This study used baseline and 1-month data collected from the 2:1 sample of women (N=2349) and men (N=1152) ages 18 to 55 years with AMI. Median age was 48 years. Among those who reported discussing sexual activity with a physician in the month after AMI (12% of women, 19% of men), 68% were given restrictions: limit sex (35%), take a more passive role (26%), and/or keep the heart rate down (23%). In risk-adjusted analyses, factors associated with not discussing sexual activity with a physician included female gender (relative risk, 1.07; 95% confidence interval, 1.03-1.11), age (relative risk, 1.05 per 10 years; 95% confidence interval, 1.02-1.08), and sexual inactivity at baseline (relative risk, 1.11; 95% confidence interval, 1.08-1.15). Among patients who received counseling, women in Spain were significantly more likely to be given restrictions than U.S. women (relative risk; 1.36, 95% confidence interval, 1.11-1.66)., Conclusions: Very few patients reported counseling for sexual activity after AMI. Those who did were commonly given restrictions not supported by evidence or guidelines., Clinical Trial Registration Url: http://www.clinicaltrials.gov.
