Cockburn J, Kemp T, Ludman P, et al. - This study offers an octogenarian risk score that could be a beneficial means to ascertain the likelihood of a successful outcome in elderly patients presenting for percutaneous coronary intervention (PCI).

• As octogenarians are a high-risk group presenting for PCI, therefore, this study was conducted to develop a 30-day mortality risk model for octogenarians presenting with both acute coronary syndrome and chronic stable angina, utilizing comprehensive mandatory UK data submissions to the UK National database.

• A predictive score was constructed which comprised the following weightings: age 80–89 (n = 1); age > 90 (n = 2); unstable angina/non-ST-elevation myocardial infraction (NSTEMI) (n = 1); STEMI (n = 2); creatinine >200 mmol/L (n = 1); preprocedural ventilation (n = 1); left ventricular ejection fraction <30% (n = 1); cardiogenic shock (n = 2).

• The patient cohort was split into a derivation (n = 22,072) and a validation dataset (n = 22,071).

• In receiver operating characteristic analyses, an AUC of 0.83, (95% CI 0.80–0.85) was yielded by the scoring system, indicating high sensitivity and specificity.

• Good survival was observed in relation to scores of 1–4 but scores ≥5 were linked with an estimated probability of death within 30 days of ≥40%.
