{Abstract}: Background Using contemporary data from NORIC (Norwegian Registry of Invasive Cardiology) we investigated the predictive value of patient age and time from ECG diagnosis to sheath insertion (ECG-2-sheath) in primary percutaneous coronary intervention for ST-segment-elevation myocardial infarction (STEMI). Methods and Results Data from 11 226 patients collected from all centers offering 24/7/365 primary percutaneous coronary intervention service were explored. For patients aged <80 years the mortality rates were 5.6% and 7.6% at 30 days and 1 year, respectively. For octogenarians the corresponding rates were 15.0% and 24.2%. The Cox hazard ratio was 2.02 (1.93-2.11, P value <0.0001) per 10 years of patient age. Time from ECG-2-sheath was significantly associated with mortality with a 3.6% increase per 30 minutes of time. Using achievement of time goal <90 minutes in patients aged >80 years and mortality at 30 days, mortality was 10.5% and 17.7% for <90 or ≥90 minutes, respectively. The number needed to prevent 1 death was 39 in the whole population and 14 in the elderly. Restricted mean survival gains during median 938 days of follow-up in patients with ECG-2-sheath time <90 minutes were 24 and 76 days for patients aged <80 and ≥80 years, respectively. Conclusions Time from ECG-diagnosis to sheath insertion is strongly correlated with mortality. This applies especially to octogenarians who derive the most in terms of absolute mortality reduction.
