To investigate the effects sex and age on prehospital delay time (PHDT) in patients with ST-segment elevation myocardial infarction.
Between January 2014 and December 2014, 465 consecutive patients with ST-segment elevation myocardial infarction who were referred to Beijing Anzhen Hospital were analyzed. According to prehospital system delay the patients were categorized into 5 groups <1h group;<2h group;<4h group;<6h group and <12h group. Linear regression models were used to examine median PHDT and individual PHDT over time. Fisher test and chi-square test were applied to analyze data for different sex and the same different respectively.
Of 380 patients with ST-segment elevation myocardial infarction, 125 received EMS and were analyzed. A minority of 27.2% of patients reached hospital within 1 h of patients with ST-segment elevation myocardial infarction. PHDT of female was longer than that of male (322 (72-887 quartiles) min vs. 245 (6-3155) min; p < 0.002). PHDT of younger male (25-54years) was 240 (6-2730) min and mounted to 303 (72-848) min in the oldest female subgroup (65-74 years).
Older female sex was associated with prolonger PHDT. Room for improvement especially in older women was evidenced.
