Usefulness of a Novel Risk Score to Predict In-Hospital Mortality in Patients ≥ 60 Years of Age with ST Elevation Myocardial Infarction.

Numerous algorithms are available to predict short-term mortality in ST elevation myocardial infarction (STEMI) but none are focused on elderly patients or include invasive hemodynamics. A simplified risk score (LASH score) including left ventricular end diastolic pressure > 20 mm Hg, age > 75 years, systolic blood pressure 100 bpm was tested in a retrospective, single-center study of 346 patients ≥ 60 years old who underwent primary percutaneous coronary intervention (PPCI). The median age was 70 years [IQR: 64, 79], 60.1% were men, and 77.8% identified as White. In-hospital all-cause mortality was 10.1%. Patients with a LASH score ≥ 3 (n = 34) had an in-hospital mortality rate of 44.1% compared to 6.4% for LASH score ≤ 2 (p
