Matters of the Heart: Case-Crossover Analysis of Myocardial Infarction on Valentine's Day
We studied the risk of myocardial infarction on Valentine's Day. We conducted a case-crossover study of 51,450 adults with myocardial infarctions in February, 1989-2019. The exposure was Valentine's Day, and the 2 days before and after Valentine's Day. We estimated odds ratios (OR) to...

We estimated odds ratios (OR) to compare days when myocardial infarction occurred with neighboring control days. Compared with other days, Valentine's Day was associated with lower odds of myocardial infarction the following day for men (OR 0.91, 95% confidence interval 0.85-0.98), but not for men and women combined (OR 0.95, 95% confidence interval 0.91-1.01). Risk of myocardial infarction in men is lower the day after Valentine's Day. Résumé: Nous avons étudié le risque de subir un infarctus du myocarde le jour de la Saint-Valentin. Nous avons réalisé une étude selon la méthode cas-croisé portant sur 51 450 adultes ayant subi un infarctus du myocarde en février entre 1989 et 2019. La période d'exposition était le jour de la Saint-Valentin ainsi que les 2 jours précédant et suivant celui-ci. Nous avons estimé les rapports de cotes (RC) pour comparer les jours où étaient survenus des infarctus du myocarde et les jours témoins voisins de cette date. Comparativement aux autres jours, le jour de la Saint-Valentin était associé à une probabilité plus faible d'infarctus du myocarde le lendemain chez les hommes (RC 0,91, intervalle de confiance à 95 % : de 0,85 à 0,98), mais pas chez les hommes et les femmes analysés ensemble (RC 0,95, intervalle de confiance à 95 % : de 0,91 à 1,01).
