Objective: Type I acute myocardial infarction (AMI) is a life-threatening condition. Time of event and rescue procedures, and sex-specific differences may play a crucial role. We aimed to investigate chronobiological patterns and sex-specific differences in a cohort of AMI patients referred to a single hub center in Italy. Patients and methods: We considered all patients consecutively admitted for AMI (STEMI) to the Hospital of the Heart, in Massa, Tuscany (a region of Italy), between 2006 to 2018, who underwent interventional procedures. Sex, age, time of hospital admission, outcome (discharged alive/deceased), main comorbidities, and time between symptom onset and emergency medical service (EMS) activation, were analyzed. Chronobiologic analysis was applied according to hour of day, month, and season of the year. Results: Overall 2,522 patients (mean age 64.6±13.1 years, 73% males) were considered. In-hospital death (IHM) occurred in 96 subjects (3.8%). At univariate analysis, deceased subjects were more likely to be female, older, with longer wait for EMS activation and with interventional procedures during night-time. The multivariate analysis identified female sex, age, history of ischemic heart disease, and night-time interventional procedure as independently associated factors to IHM. Chronobiologic analysis showed a pattern with a main morning peak for total sample, males, and females (p=0.00027; p=0.0006); p=0.0121, respectively). Events showed a higher peak in summer, with no differences by sex, but IHM was higher in winter. Females showed a higher delay for EMS activation, compared to males (p<0.001), but with no effects on prognosis. On the contrary, males with a delay showed higher mortality. Conclusions: Great effort should be spent to reduce patient-related delays in interventional procedures, being this issue crucial in both sexes.

Abstract

Objective: Type I acute myocardial infarction (AMI) is a life-threatening condition. Time of event and rescue procedures, and sex-specific differences may play a crucial role. We aimed to investigate chronobiological patterns and sex-specific differences in a cohort of AMI patients referred to a single hub center in Italy. Patients and methods: We considered all patients consecutively admitted for AMI (STEMI) to the Hospital of the Heart, in Massa, Tuscany (a region of Italy), between 2006 to 2018, who underwent interventional procedures. Sex, age, time of hospital admission, outcome (discharged alive/deceased), main comorbidities, and time between symptom onset and emergency medical service (EMS) activation, were analyzed. Chronobiologic analysis was applied according to hour of day, month, and season of the year. Results: Overall 2,522 patients (mean age 64.6±13.1 years, 73% males) were considered. In-hospital death (IHM) occurred in 96 subjects (3.8%). At univariate analysis, deceased subjects were more likely to be female, older, with longer wait for EMS activation and with interventional procedures during night-time. The multivariate analysis identified female sex, age, history of ischemic heart disease, and night-time interventional procedure as independently associated factors to IHM. Chronobiologic analysis showed a pattern with a main morning peak for total sample, males, and females (p=0.00027; p=0.0006); p=0.0121, respectively). Events showed a higher peak in summer, with no differences by sex, but IHM was higher in winter. Females showed a higher delay for EMS activation, compared to males (p<0.001), but with no effects on prognosis. On the contrary, males with a delay showed higher mortality. Conclusions: Great effort should be spent to reduce patient-related delays in interventional procedures, being this issue crucial in both sexes.
